Background. Lack of water supply and sanitation infrastructure in rural areas affects people’s health, welfare and living conditions, negatively impacts the rural environment, and can stall rural development and prosperity. Improving equitable and sustainable access to safe and improved water supply and sanitation in rural areas is therefore an important national development objective. This article presents to what extend the welfare level of the rural women in Uzbekistan correlates with socio-economic factors such as access to water supply and sanitation services in Uzbekistan. Methods. This article is based on comparative analysis of the gender aspects of welfare of rural women in Bukhara region. The gender aspects assessment of the water supply and sanitation sector identifies that rural women experience the unequal access to infrastructure in comparison with urban population and urban women. The utilizing of the concept of analysis based on identification of inequalities by going “beyond income, beyond averages and beyond today” demonstrates that there is no direct impact of the socio-economic factors on poverty rate of the family [1;6].

Abstract According to the World Bank's collection of development indicators, in 2017 approximately 25% of Malaysia's population were living in rural villages. Some of these villages are currently without electricity from the national grid and public piped water supply. In this study, a solar-powered ultrafiltration membrane water treatment system was installed at a rural village in Perak, Malaysia, to identify its feasibility. The ultrafiltration system was evaluated and compared with a conventional sand/media filtration water treatment system at the same location. Various aspects of both systems such as operational parameters, life-cycle cost and carbon emissions have been analyzed under this study. The distinct advantages of the ultrafiltration system include better filtrate turbidity quality (below 0.4 NTU), and lower operational cost and carbon emission. By utilizing a cross-flow filtration operation mode, the UF system does not require a daily intermittent backwash sequence, unlike the conventional system, to further simplify the daily operational routine. Accessibility of clean water supply for all has been heavily emphasized by the United Nations General Assembly (under sustainable development goal number 6) to ensure public health. This comprehensive study highlights the feasibilities of solar-powered ultrafiltration membrane water treatment systems for rural villages in Malaysia.

A project was designed by Umgeni Water (funded by the Water Research Commission of South Africa) to monitor the implementation of water reticulation in Vulindlela and evaluate the Water Supply Scheme from a community and environmental health perspective. The findings would hopefully contribute toward the development of criteria for Health Impact Assessment on Water Reticulation Projects. One objective of this study was to evaluate the usefulness of diarrhoeal disease as opposed to other health indicators for water-associated diseases. The innovative methodology followed in the study, a “stepped wedge design”, compared four discrete areas of water reticulation implementation in Vulindlela over a 15-month period. Five surveys, including a baseline and four follow-ups at each household, were carried out. Analysis (microbiological, chemical) was carried out of samples from the household drinking water and from the source of the water. Each survey included health questionnaires, the respondent being the head of the household in each case. Overall, there was no direct correlation proved between water quality and diarrhoea per se. However, there was a marked decrease in diarrhoea with the introduction of the new water supply. There was definite correlation between hygiene behaviours and diarrhoea. Diarrhoea would seem to be the health impact associated with water, of choice.

OBJECTIVE: To understand beliefs and attitudes about fluorosis among young people living in a rural area. METHODOLOGICAL PROCEDURES: Qualitative study consisting of semi-structured interviews with 23 adolescents with dental fluorosis, 14 teachers and three health authorities in the city of São Francisco, Southeastern Brazil, in 2002. Content analysis and social representation theory were applied. ANALYSIS OF RESULTS: The organoleptic characteristics of carbonates that affect groundwater (salty flavor, whitish coloration, and turbidity) associated with negative aspects of household use of this water are considered a cause of mottled enamel. Even after contact with researchers who investigated this phenomenon and helped find a solution for this condition, the local population is still unwilling to accept fluoride as the cause of the problem and does not fully agree to use water from other sources because they are afraid of the quality of water. CONCLUSIONS: Misperceptions of the causes of dental fluorosis and water treatment costs compromise the implementation of uncontaminated surface water supplies. Health education strategies are required in parallel with solutions for securing water supply in drought-ravaged areas.

The incidence rate of inflammatory bowel disease (IBD) is becoming a global health problem that could be caused by changes in environmental and lifestyle habits. The study aimed to identify the association between the quality of drinking water, i.e., physiochemical and biological aspects of the phenotype and activity of IBD in Eastern Croatia. The study included 312 patients (63.4% ulcerative colitis, UC, and 36.6% Crohn’s disease, CD) from the area of Eastern Croatia. The data were collected by questionnaires and the analysis of the water safety, based on 65 samples of drinking water by the patient’s water supply method (public supply, rural water supply, and private well). IBD was active in 38.0% patients (34.0% CD and 40.0% UC). Significant differences (p = 0.001) were observed in the distribution of patients, according to counties in which they lived in. The largest deviation was noted in coliform bacteria, Escherichia coli, and enterococci bacteria, Fe, Al, and nitrate in rural water supply and private wells, although, without significant impact on IBD phenotype and activity. The hazard quotient (HQ) simulations showed that children are a sensitive group, regarding exposure to nitrates in drinking water over a long period of time, so there is a need for further monitoring and analysis of this issue.

Growing population, increasing urbanization, and rural to urban migration, coupled with the ongoing climate change, threaten the sustainability of cities, particularly in developing countries. Previous studies indicate numerous deficiencies in the water supply and sewage systems of Islamabad; however, a comprehensive insight into the water security assessment has not been carried out. Therefore, this study is aimed at assessing the urban water security of Islamabad by taking both human and environmental aspects into consideration. In principle, we achieve this objective by implementing the Water Security Assessment Framework, using five distinct parameters to calculate an urban water security index. The water supply dimension incorporates availability, accessibility, affordability, and the quality of drinking water in the city, whereas, sanitation and health dimension measures access to improved drainage systems as well as the state of overall hygiene of the city inhabitants. Furthermore, the water economy dimension includes water productivity and investment aspects in the study area, while the environment and ecosystem dimension looks into the current state of natural water bodies. Similarly, overall management and public support for freshwater resources are measured in the society and governance dimension. In general, we attempt to better comprehend water-security nexus in the federal capital considering it as a prerequisite to ensure a sustainable future for the city dwellers.

Infrastructure development
Infrastructural development is a key requirement for the development of any nation as it is an indispensable tool in facilitating growth and development. The usefulness of infrastructure cuts across many varying sectors relevant to development including health, education, agriculture, telecommunication, power, etc. as well as the sustenance of economic growth and preservation of the environment for sustainable economic development. This article takes a look at the critical areas/aspects of infrastructure for the purpose of judging the level of accomplishment of the Vision 2020. The sectors examined are: power supply, transportation, information communication and technology (ICT), education, health, agriculture, land use management, rural and urban development, water supply and waste management. By and large, Nigeria can not be said to have met her tall, yet laudable goals of the vision 2020, largely as a result of inadequacies in governance, policies and other factors. There is a great need for significant improvement in the political will of the government of the day to commit to the goals and aspirations of the nation for rapid development.

The conventional handpump is the most popular technology choice for improved potable water supplies in rural sub-Saharan Africa. To date, however, it has failed to deliver satisfactory levels of sustainability, largely due to inadequate maintenance capacity. An alternative option to standardised imported handpumps is the locally manufactured rope-pump, which is considerably cheaper and easier to maintain but has been rejected in the past due to fears of impaired water quality. This paper presents the key aspects of a study in northern Ghana which compared the performance of rope-pumps with that of conventional handpumps, to determine whether or not the rope-pump provides a viable alternative for community water supplies across the sub-continent. User interviews, sanitary surveys, water quality analyses and technical performance measurements were used to develop a comparative performance analysis for the two pump types. The findings of the study indicated that the rope-pump out-performed the conventional handpump on the majority of counts and that, contrary to widespread perceptions, there was no significant difference between pump types with respect to the impact on microbiological water quality. Consequently, the rope-pump provides a significant technological opportunity to improve water supply sustainability in Africa.

Este trabalho mostra os resultados de uma pesquisa sobre as condições sanitárias de algumas comunidades rurais, situadas no alto trecho do rio Pajeú, semiárido pernambucano. Nos períodos de estiagem, os açudes e poços são as fontes de águas mais utilizadas para o abastecimento das cisternas, equipamento de reservação presente em 100% das residências visitadas. As águas de três dessas fontes foram classificadas como doces, de acordo com a legislação em vigor.A forma de tratamento mais usada para as águas de consumo doméstico foi a aplicação de hipoclorito. Quanto aos resíduos gerados pelas famílias, onde a coleta pública municipal não está presente, o principal destino dos resíduos é a queima a céu aberto. Os dejetos de animais são, em sua maioria, utilizados como fertilizantes, embora tenha sido observada a presença desses resíduos em algumas nascentes. De forma geral, as principais práticas sanitárias encontradas nas comunidades visitadas, em sua maioria, são caracterizadas pela individualidade, devido à ausência de serviços públicos coletivos. Algumas práticas, como a queima de resíduos sólidos é diretamente nociva à saúde das pessoas, além de poder se constituir em uma importante fonte de poluição, à medida que a população e a quantidade de resíduos aumentam. Por outro lado, as famílias entrevistadas apresentaram certo nível de conhecimento quanto à necessidade de descontaminação da água usada para beber e cozinhar, e o aproveitamento agrícola dos nutrientes contidos nos dejetos de animais.Palavras-chave: saneamento básico; comunidades rurais; semiárido. Aspects of Sanitation and Use of Waterin Small Rural Communities of Pernambuco’s Semiarid ABSTRACTThis article shows the results of a research about the health conditions of some rural communities, located on the upper course of Pajeú River, in the semiarid region of Pernambuco State, Brazil. In periods of drought, dams and wells are the most used sources of water for the supply of cisterns, which are tanks or containers, for storing or holding water that are present in 100% of the visited homes. The water from three of those sources was classified as freshwater, according to the legislation. The most widely used form of treatment of water for domestic consumption was the use of hypochlorite. The waste generated by households where the municipal public collection is not available is, most of the time, burned in the open air. Animal manure is commonly used as fertilizer, although its presence has also been observed in some river sources. Overall, the main sanitary practices found in the communities visited are, in their majority, characterized by individuality, due to the absence of collective public services. Some practices, such as burning solid waste, is directly harmful to people's health, and can constitute an important source of pollution, as the population and the amount of waste increase. On the other hand, the families that were interviewed had some level of knowledge on: (i) the need for decontamination ofwater used for drinking and cooking; and (ii) the use of the nutrients contained in animal manure in agriculture.Keywords: sanitation; rural communities; semiarid.

Abstract Three novel and two commercially available low-cost point-of-use (PoU) water treatment technologies were comparatively evaluated using a specialized comparison framework targeted at them. The comparison results and specialized framework have been discussed. The PoU systems were evaluated principally in terms of performance, flow rate and cost per volume of water treated (quantitatively), ease of use, potential acceptability and material availability (qualitatively) with main focus on rural and suburban settings. The three novel systems assessed were developed in an ongoing research project aimed at developing a multibarrier low-cost PoU water treatment system. The comparative evaluation and analysis revealed that the commercially available systems may often produce water free of pathogens (with an apparent 100% removal for Escherichia coli and fecal coliforms) but may not be affordable for application to the poorest groups in much of the developing world. The novel systems, which were principally constructed from local materials, were more affordable, can supply relatively safe water and can be constructed by users with minimal training. Overall, bacterial removal effectiveness, ease of use, flow rate, material availability, cost and acceptability aspects of water were identified as key to potential adoption and sustainability of the evaluated low-cost PoU systems.

Thesis (MTech (Chemical Engineering))--Peninsula Technikon, Cape Town, 2003The monitoring of pesticide contamination in surface and groundwater is an essential aspect of an assessment of the potential environmental and health impacts of widespread pesticide use. Previous research in three Western Cape farming areas found consistent (37% to 69% of samples) pesticide contamination of rural water sources. However, despite the need, monitoring of pesticides in water is not done due to lack of analytical capacity and the cost of analysis in South Africa. The Solid Phase Microextraction (SPME) sampling method has been developed over the last decade as a replacement for solvent-based analyte extraction procedures. The method utilizes a short, thin, solid rod of fused silica coated with an absorbent polymer. The fibre is exposed to the pesticide contaminated water sample under vigorous agitation. The pesticide is absorbed into the polymer coating; the mass absorbed depends on the partition coefficient of the pesticide between the sample phase and the polymeric coating, the exposure time and factors such as agitation rate, the diffusivity of the analyte in water and the polymeric coating, and the volume and thickness of the coating. After absorption, the fibre is directly inserted into the Gas Chromatograph (GC) injection port for analysis. For extraction from a stirred solution a fibre will have a boundary region where the solution moves slowly near the fibre surface and faster further away until the analyte is practically perfectly mixed in the bulk solution by convection. The boundary region may be modelled as a layer of stationary solution surrounded by perfectly mixed solution.

Full textAbstract:
Water is an indispensible and yet a difficult resource to be renewed, thus water scarcity has become one of the major challenges faced worldwide, with the Southern regions of Africa being the most impacted and affected, especially the Eastern Cape Province of South Africa where rural communities depend on receiving waterbodies that are often negatively impacted by wastewater final effluents. This present study was conducted between August and December 2010 to assess the physicochemical and microbial qualities of the final effluents of peri-urban and rural communities based wastewater treatment plants in the Eastern Cape Province. The physicochemical parameters were determined on site and in the laboratory, while bacteriological qualities were determined using culture based techniques. The virological qualities were determined by molecular methods using reverse transcriptase polymerase chain reaction for the target RNA virus and the conventional polymerase chain reaction for the target DNA virus. For both wastewater treatment plants, the physicochemical parameters ranged as follows: chemical oxygen demand (5.95-45 mg/L); total dissolved solids (114.5-187.0 mg/L); salinity (0.12-0.20 psu); temperature (14.2-25.7oC); pH (6.0-7.6); nitrate and nitrites (1.55-6.7 mg/L and 0.023-1.15 mg/L respectively); biological oxygen demand (3.5-7.8 mg/L); turbidity (1.49-6.98 NTU); and chlorine residual (0-2.97 mg/L). Feacal indicator bacteria counts ranged as follows: feacal coliforms (0-1.25×104 cfu/100 ml); total coliforms (0-3.95×104 cfu/100 ml); and enterococci (0-5.0×103 cfu/100 ml). xviii Seventy five percent of the rural community based plant and 80 percent of the peri-urban community based plant were positive for coxsackie A virus, while hepatitis A virus was detected in all the rural community based plant 80 percent of the peri-urban community based plant. This study suggests the need for intervention by appropriate regulatory agencies to ensure regular monitoring of the qualities of final effluents of wastewater treatment facilities in the Eastern Cape Province and ensure compliance to established guidelines.

Full textAbstract:
In 1998, Western Kentucky University (WKU) worked in collaboration with the Environmental Protection Agency (EPA), Drinking Water Protection Division, to investigate methods to improve source-water quality for rural-water supply systems (RWSS). Through partial funding from the EPA, WKU developed a Technical Assistance Center for Water Quality (TACWQ), which focused resources and expertise toward assisting RWSS in achieving and maintaining capacity development goals and protecting public health. The TACWQ established the Source Water Protection Initiative (SWPI) to assist RWSS in acquiring and monitoring the technical, financial and managerial capacity needed to provide safe drinking water and achieve the public health protection goals of the EPA Safe Drinking Water Act (Technical Assistance Center, July 1998). The SWPI also provided technical assistance toward identifying and reducing source water impacts throughout Kentucky. Monthly sampling during 2000 from seven watersheds in western and south central Kentucky showed that levels of several pesticides and herbicides were elevated above Maximum Contaminant Levels (MCLs) in their source waters. Of the MCL exceedences, three commonly used pesticides (atrazine, alachlor, and simazine) were repeatedly being detected at several sites. Of the three compounds, atrazine, a triazineclass herbicide widely used in Kentucky to control broad leaf and grassy weeds in row crops such as corn, drew the most interest. Atrazine has been classified as a spring use only, "Restricted Use Pesticide due to its potential for groundwater contamination." (EXTOXNET, 1996) It is regulated as a compound with class III (slight) toxicity. In 1994, EPA took atrazine under special review to evaluate the ecological and biological effects it may cause. EPA later deemed atrazine not to significantly increase the risk of cancer in humans and went as far as lifting its use restrictions. Independent researchers still dispute EPA claims. The exceedences of the MCLs by many compounds in source water do not immediately result in violations. The source water must go through treatment processes. Water-supply operators must strive to meet National Primary Drinking Water Standards (EPA, 1999) prior to going to the consumer. However, the fundamental concept driving the SWPI is that the technical and financial challenges faced by RWSS are proportional to the quality of their source water. At several sites, even treated water that was distributed to customers exceeded federally mandated MCLs. Levels of atrazine in finished water reached 17 parts per billion (ppb) in Lewisburg, Kentucky. The MCL for atrazine is currently 3.0 ppb.

Full textAbstract:
Globally, there is still a large number of people without access to safe drinking water; a known health risk. In rural areas of countries like Peru, when potable water systems are built the responsibility for maintaining these systems is given to volunteer water committees. Despite its prevalence as a management model, there is a consensus that community management alone cannot ensure sustainable water service. Therefore, the overall goal of this research is to assess the sustainability of community-managed water systems in rural areas of the department of Amazonas, Peru. Specifically, this research examines two mechanisms that have been shown to improve the sustainability of rural water systems: 1) monitoring for asset management and service delivery, and 2) provision of long-term external support.
In Amazonas, three sustainability assessment tools have been used recently to monitor the service level and management of water systems. These assessment tools are: the Rural Water and Sanitation Information System (SIASAR, in Spanish), Tracers in Rural Water and Sanitation (Trazadores, in Spanish), and the Diagnostic Survey for Water Supply and Sanitation (Diagnostico, in Spanish). The three tools were assessed using a question mapping technique as well as a sustainability assessment tool evaluation matrix. This analysis identified the SIASAR assessment tool to be the most appropriate for ensuring sustainability of rural water supply systems.
This research also used the data collected with the SIASAR and Trazadores assessment tools to assess the state of community-managed rural water systems in Amazonas. The analysis showed that 81% of systems in the SIASAR analysis and 58% of systems in the Trazadores analysis have deficiencies that are beyond the ability of the water committee to overcome.
In recent years, the Peruvian government has prioritized the creation of an office in each district dedicated to providing external technical support to local water committees. This office, called the Área Técnica Municipal de Agua y Saneamiento (ATM), is charged with formalizing and training water committees which are given the name, Juntas Administradoras de los Servicios de Saneamiento (JASS).
In order to examine the provision of long-term external support provided by the ATM to the JASS, field research was conducted in six districts in Amazonas. Valuable anecdotal evidence was provided by the field research that helped to form recommendations for strengthening the capacity of the ATM office at the local municipal level.
The results of this research demonstrate that currently a large number of community-managed rural water systems in Amazonas are not sustainable but that the prioritization of monitoring and external support is an encouraging sign. If these mechanisms continue to be prioritized then it is highly likely that water systems throughout Amazonas and Peru will become more sustainable, bringing benefits to millions of Peruvians in rural areas.

Full textAbstract:
Eighty percent of the 780 million people worldwide that access water from an unimproved source live in rural areas. In rural areas, water systems are often managed by community based organizations and many of these systems do not provide service at the designed levels. The Sustainability Analysis Tool developed in Chapter 2 can inform decision making, characterize specific needs of rural communities in the management of their water systems, and identify weaknesses in training regimes or support mechanisms. The framework was tested on 61 statistically representative geographically stratified sample communities with rural water systems in the Dominican Republic. The results demonstrated the impact that long term support by outside groups to support community management activities can improve sustainability indicators, including financial sustainability which is a significant issue throughout the world.
When analyzing the financial sustainability of water systems, it is important to consider all life-cycle costs including the expenditures made by households. Chapter 3 analyzes financial and economic expenditures on water services in 9 rural and peri-urban communities in Burkina Faso. Data from household and water point surveys were used to determine: socio-economic status, financial and economic expenditures, and service levels received by each household. In Burkina Faso recurrent financial and economic expenditures on water service ranged between US$5 and US$9.5 per person per year, with cumulative costs approximately US$19.5 per person per year. The average expenditures on water in Burkina Faso were well above the affordability threshold used by World Bank demonstrating the need to improve subsidies in the water sector.
The sustainability of water supply systems and the ability to ensure the health benefits of these systems is also influenced by the deficiencies in sanitation infrastructure. Unimproved sanitation can be a source of water contamination and a risk factor in water related disease. Furthermore, the effective management of community water supply infrastructure is not a sufficient condition for ensuring water quality and eliminating health risks to consumers. As a result water treatment technologies, such as ceramic water filters (CWFs), implemented and managed at the household level and combined with safe storage practices are proposed as a means of reducing these risks.
The performance of CWFs in laboratory settings has differed significantly from field studies with regard to microbial treatment efficacy and also hydraulic efficiency. Chapter 4 presents a 14 month field study of two locally manufactured CWFs conducted in a rural community in the Dominican Republic. Each of the 59 households in the community received one filter. The CWFs in this study performed poorly with regard to water quality and hydraulic performance. Focus group meetings and household survey suggests that flow rate is a major issue for user acceptability. To address the user concerns Chapter 5 presents two mathematical models for improving the hydraulic performance for the frustum and paraboloid designs. The models can be used to predict how changes in user behavior or filter geometry affects the volume of water produced and therefore can be used as tools to help optimize filter performance.

Full textAbstract:
Water, sanitation and hygiene-related diseases are responsible for 7% of all deaths and 8% of all disability adjusted live years (DALYs), as well as the loss of 320 million days of productivity in developing countries. Though laboratory and field trials have shown that household water treatment (HWT) technologies can quickly improve the microbiological quality of drinking water, questions remain about the effectiveness of these technologies under real-world conditions. Furthermore, the value that rural communities attach to HWT is unknown, and it is not clear why, in spite of the fact that rural African households need household water treatment (HWT) most, they are the least likely to use them. The primary objective of this multi-level study was to assess the post-implementation effectiveness of selected HWT technologies in the Nyanza and Western Provinces of Kenya. The study was carried out in the rainy season between March and May, 2011 using a mixed method approach. Evidence was collected in order to build a case of evidence of HWT effectiveness or ineffectiveness in a post-implementation context. A quasi-experimental design was used first to conduct a Knowledge, Attitudes and Practices (KAP) survey in 474 households in ten intervention and five control villages (Chapter 3). The survey assessed the context in which household water treatment was being used in the study villages to provide real-world information for assessing the effectiveness of the technologies. An interviewer-administered questionnaire elicited information about the water, sanitation and hygiene-related KAP of the study communities. A household water treatment (HWT) survey (Chapter 4) was carried out in the same study households and villages as the KAP study, using a semi-structured questionnaire to gather HWT adoption, compliance and sustained use-related information to provide insight into the perceived value the study households attach to HWT technologies, and their likelihood of adoption of and compliance with these technologies. The drinking water quality of 171 (one quarter of those surveyed during KAP) randomly selected households was determined and tracked from source to the point of use (Chapter 5). This provided insights into HWT effectiveness by highlighting the need for HWT (as indicated by source water quality) and the effect of the study households’ KAP on drinking water quality (as indicated by the stored water quality). Physico-chemical and microbiological water quality of the nineteen improved and unimproved sources used by the study households was determined, according to the World Health Organisation guidelines. The microbiological quality of 291 water samples in six intervention and five control villages was determined from source to the point-of-use (POU) using the WHO and Sphere Drinking Water Quality Guidelines. An observational study design was then used to assess the post-implementation effectiveness of the technologies used in 37 households in five intervention villages (Chapter 6). Three assessments were carried out to determine the changes in the microbiological quality of 107 drinking water samples before treatment (from collection container) and after treatment (from storage container) by the households. The criteria used to assess the performance of the technologies were microbial efficacy, robustness and performance in relation to sector standards. A Quantitative Microbial Risk Assessment (QMRA) was then carried out in the HWT effectiveness study households to assess the technologies’ ability to reduce the users’ exposure to and probability of infection with water-borne pathogens (Chapter 7). The KAP survey showed that the intervention and control communities did not differ significantly in 18 out of 20 socio-economic variables that could potentially be influenced by the structured manner of introducing HWT into the intervention villages. The majority of the intervention group (IG) and the control group (CG) were poor or very poor on the basis of household assets they owned. The predominant level of education for almost two-thirds of the IG and CG respondents was primary school (completed and non-completed). Though very few were unemployed in IG (8.07%) and CG (14.29%), the two groups of respondents were predominantly engaged in subsistence farming — a low income occupation. With regard to practices, both groups had inadequate access to water and sanitation with only one in two of the households in both IG and CG using improved water sources as their main drinking water source in the non-rainy season. One in ten households in both study groups possessed an improved sanitation facility, though the CG was significantly more likely to practice open defecation than the IG. The self-reported use of soap in both study groups was mainly for bathing and not for handwashing after faecal contact with adult or child faeces. Despite the study groups' knowledge about diarrhoea, both groups showed a disconnection between their knowledge about routes of contamination and barriers to contamination. The most frequent reason for not treating water was the perceived safety of rain water in both the IG and CG.The HWT adoption survey revealed poor storage and water-handling practices in both IG and CG, and that very few respondents knew how to use the HWT technologies correctly: The IG and CG were similar in perceived value attached to household water treatment. All HWT technologies had a lower likelihood of adoption compared to the likelihood of compliance indicators in both IG and CG. The users’ perceptions about efficacy, time taken and ease of use of the HWT technologies lowered the perceived value attached to the technologies. The assessment of the drinking water quality used by the study communities indicated that the improved sources had a lower geometric mean E. coli and total coliform count than the unimproved sources. Both categories of sources were of poor microbiological quality and both exceeded the Sphere Project (2004) and the WHO (2008) guidelines for total coliforms and E. Coli respectively The study communities’ predominant drinking water sources, surface water and rainwater were faecally contaminated (geometric mean E. coli load of 388.1±30.45 and 38.9±22.35 cfu/100 ml respectively) and needed effective HWT. The improved sources were significantly more likely than the unimproved sources to have a higher proportion of samples that complied with the WHO drinking water guidelines at source, highlighting the importance of providing improved water sources. The lowest levels of faecal contamination were observed between the collection and storage points which coincided with the stage at which HWT is normally applied, suggesting an HWT effect on the water quality. All water sources had nitrate and turbidity levels that exceeded the WHO stipulated guidelines, while some of the improved and unimproved sources had higher than permissible levels of lead, manganese and aluminium. The water source category and the mouth type of the storage container were predictive of the stored water quality. The active treater households had a higher percentage of samples that complied with WHO water quality guidelines for E. coli than inactive treater households in both improved and unimproved source categories. In inactive treater households, 65% of storage container water samples from the improved sources complied with the WHO guidelines in comparison to 72% of the stored water samples in the active treater households. However the differences were not statistically significant. The HWT technologies did not attain sector standards of effective performance: in descending order, the mean log10 reduction in E. coli concentrations after treatment of water from unimproved sources was PUR (log₁₀ 2.0), ceramic filters (log₁₀ 1.57), Aquatab (log₁₀ 1.06) and Waterguard (log₁₀ 0.44). The mean log10 reduction in E. coli after treatment of water from improved sources was Aquatab (log₁₀ 2.3), Waterguard (log₁₀ 1.43), PUR (log₁₀ 0.94) and ceramic filters (log₁₀ 0.16). The HWT technologies reduced the user’s daily exposure to water-borne pathogens from both unimproved and improved drinking water sources. The mean difference in exposure after treatment of water from unimproved sources was ceramic filter (log₁₀ 2.1), Aquatab (log₁₀ 1.9), PUR (log₁₀ 1.5) and Waterguard (log₁₀ 0.9), in descending order. The mean probability of infection with water-borne pathogens (using E.coli as indicator) after consumption of treated water from both improved and unimproved sources was reduced in users of all the HWT technologies. The difference in reduction between technologies was not statistically significant. The study concluded that despite the apparent need for HWT, the study households’ inadequate knowledge, poor attitudes and unhygienic practices make it unlikely that they will use the technologies effectively to reduce microbial concentrations to the standards stipulated by accepted drinking water quality guidelines. The structured method of HWT promotion in the intervention villages had not resulted in more hygienic water and sanitation KAP in the IG compared to the CG, or significant differences in likelihood of adoption and compliance with the assessed HWT technologies. Despite attaching a high perceived value to HWT, insufficient knowledge about how to use the HWT technologies and user concerns about factors such as ease of use, accessibility and time to use will impact negatively on adoption and compliance with HWT, notwithstanding their efficacy during field trials. Even though external support had been withdrawn, the assessed HWT technologies were able improve the quality of household drinking water and reduce the exposure and risk of water-borne infections. However, the improvement in water quality and reduction in risk did not attain sector guidelines, highlighting the need to address the attitudes, practices and design criteria identified in this study which limit the adoption, compliance and effective use of these technologies. These findings have implications for HWT interventions, emphasising the need for practice-based behavioural support alongside technical support.

Full textAbstract:
The demand-driven and participatory approach to water resource development and management in Tanzania has been both praised and criticized; some see progress where others see increased inequalities. This study focuses on one progressive, demand-driven NGO which has a participatory approach to water resource development and management. This NGO, MSABI, is active in Kilombero Valley in southern Tanzania, and can be considered successful as it manages to keep 91 % of its water points functional, whilst the national average for pump functionality is just above 50 %. To study the performance of MSABI from a user perspective, it was decided that two sites in Kilombero Valley should be investigated in terms of users’ views on water access and quality. The identification of sites is based on population density and landcover change, so that the issues of scale and urban bias, as well as changes in the landscape affecting hydrological processes, are accounted for. In total, 29 interviews were conducted (October to November 2014), 15 at the Ifakara study site, the more densely populated location, and 14 at the Mchombe Ward study site. The interviews were semi-structured, using a participatory approach, focusing on users’ perspectives on water sources and the access to and quality of those water sources in dry and rainy seasons. The information gathered was used to construct definitions for water access and quality. These definitions, as well as the two locations and categorization of participants according to socio-economic status, were then used to sort and analyse the collected material. The results show that MSABI does not manage to make water accessible in an equitable way because of its demand-driven and participatory approach to water resource development and management. However, MSABI offers the only improved water source at the Mchombe Ward study site, except for one improved open well. MSABI manages to counter urban-bias better than any of the other water resource development and management facilitators encountered at the two study sites. The seasons influence water access, especially at the more peripheral locations, where improved water sources are less common and, as open water sources, are more prone to drought and contamination. When participants in Ifakara seasonally migrate for farming, during 4-5 months per year, the majority’s access to improved water sources is lost. At the distant seasonal fields, open water sources are more common and few report that they treat the unsafe water. The migration to peripheral farmlands coincides with the rainy season, causing open water sources to have their lowest water quality when seasonal migrants utilize them. This underlines the importance of securing safe water supply for people at remote locations, and the important role MSABI plays as water resource developer at those locations. In conclusion, if the current demand-driven and participatory approach to water resource development and management is to be retained, regardless of the heavy criticism it has received with regards to equity, this study suggests that the practices of MSABI should be spread further based on MSABI’s ability to increase safe water access at remote locations. Another recommendation is to further look into the effects of seasonal migration on access to safe water. The effect seasonal migration has on water access in Kilombero could exist in other areas in Tanzania or in other countries. The aspect of seasonal migration might show that water access statistics are misleading, as the seasonal water consumption in remote locations risks being omitted in official statistics.

Saneamento ambiental é um dos mais importantes meios de controle da prevenção de doenças, de conservação do meio ambiente e de promoção da saúde. Porém, não é uma realidade em todas as partes do mundo, principalmente nos países em desenvolvimento, onde ainda se pode encontrar áreas urbanas densamente povoadas com precárias condições de saneamento, representando uma grande preocupação para os profissionais da área de saúde pública. Essa problemática revela-se particularmente importante para as pessoas que estão mais expostas a possíveis riscos de contaminação, devido à falta de infra-estrutura de saneamento, principalmente nos ambientes rurais. Este estudo teve como objetivo verificar a condição da qualidade da água utilizada para consumo humano, na comunidade da zona rural de Fortaleza de Minas - MG, por meio da identificação da origem, captação, tratamento, armazenamento e distribuição da água consumida e da análise dos seus parâmetros microbiológicos, físicos e químicos. Visou também levantar a percepção da população em relação à qualidade da água consumida. O estudo foi desenvolvido na Comunidade Rural do Bairro Chapadão do município, tendo sido utilizada a técnica de Tubos Múltiplos para as análises microbiológicas; para a identificação e quantificação dos metais, empregou-se a técnica de Espectrometria de Emissão Atômica - ICP-AES e, para os agrotóxicos, a técnica de cromatografia líquida de alta eficiência. Também foram feitas entrevistas com 15 sujeitos da comunidade rural, incluídos neste estudo. Foi detectada a presença de Escherichia coli e Coliformes Totais em todas as amostras de água investigadas, acima do valor permitido pela Portaria do Ministério da Saúde - MS no 518/2004. Foram detectados valores acima do máximo permitido para turbidez, cor aparente e pH, previstos pela Portaria MS no 518/2004. A presença dos metais arsênio, cádmio, chumbo, cobre, cromo, ferro e manganês, em algumas amostras de água, apresentaram valores acima do permitido pela Portaria MS no 518/2004. Os agrotóxicos α e β-endossulfam e metalaxil não foram identificados nas amostras de água. O método de validação desenvolvido para análise dos agrotóxicos α e β-endossulfam e metalaxil foi considerado eficiente, podendo ser empregado em futuras análises para o monitoramento de α e β-endossulfam e metalaxil em água para consumo humano. Quanto à percepção dos sujeitos sobre a qualidade da água, foi levantado que 66,67% dos entrevistados não utilizavam nenhum tipo de tratamento para a água consumida, e o mesmo percentual referiu armazenar a água em caixas de amianto. Quando perguntados sobre a qualidade da água consumida, mesmo os 46,67% dos sujeitos que referiram considerar a água de boa qualidade, também destacaram não saber se a mesma continha \"veneno\". Os resultados evidenciam a importância do tratamento da água para consumo da população deste estudo, em conformidade com as normas contidas na Portaria MS no 518/2004, que estabelece procedimentos para controle e vigilância da qualidade da água para consumo humano, visando manter um padrão de potabilidade. Também revelam a necessidade de que as políticas públicas na área da saúde e meio ambiente encontrem medidas intersetoriais voltadas para as populações da zona rural, no que se refere ao saneamento ambiental, que é uma das principais bases da promoção da saúde humana.Environmental sanitation is one of the most important means to control the prevention of diseases, the conservation of the environment, and the promotion of health. However, is not a reality in every part of the world, especially in the developing countries, where densely inhabited urban areas with precarious sanitation conditions can still be found, which represents a great concern to the professionals of public health. This problem revels itself particularly important to the people who are more exposed to possible risks of contamination, due to the lack of sanitation infrastructure, especially on rural environments. The purpose of this study is to verify the quality of the water used for human intake on the rural community if Fortaleza de Minas - MG, through the identification of the origin, captivation, treatment, storing and distribution of the water consumed, and the analysis of its microbiological, physical and chemical parameters. It also aimed to increase the population perception with regards to the quality of the consumed water. The study was developed in the Rural Community of the Chapadão neighborhood, using the Multiple Tubes technique for the microbiological analysis; for the identification and quantification of metals, the Spectrometry Atomic Emission - ICP-AES technique was used; and for the agro toxics, the high efficiency liquid chromatography technique was used. Interviews were made with 15 individuals from the rural community included in the study. The presence of Escherichia coli and Total Coliforms forms were detected in all the samples of the investigated water, above the permitted by the law 518/2004 of the Health Ministry - MS. Values above the permitted by the law 518/2004 of the Health Ministry were detected for turbidity, visible color and pH. The presence of the metals arsenic, cadmium, lead, copper, chromium, iron and manganese in same of the water samples, were higher than the values permitted by the law 518/2004 of the Health Ministry. The agro toxics α and β-endossulfam and metalaxil were not identify in the water samples. The validation method developed for the analysis of the agro toxics α and β-endossulfam and metalaxil was considered efficient, allowing it to be used in future analysis for the monitoring of α and β-endossulfam and metalaxil in human consumed water. In regards to the perception of the individuals about the quality of the water, it was verified that 66,67% of the interviewed people did not used any kind of treatment for the water consumed, and the same percentage preferred to store the water in asbestos boxes. When asked about the quality of the water consumed, even the 46,67% of the individuals that preferred to consider the water of \"good quality\", emphasized not knowing if it contained \"poison\". The results show the importance of the treatment of the water for consume of this study population, jointly with precept contain in the Health Ministry law nº 518/2004, that establish procedures to control and watch the quality of the water for human consume, aiming to keep the pattern of potability. It also revel the necessity for public politics in the health and environmental departments to find joint measures focused on the countryside population, concerning the environmental sanitation, which is one of the bases for the promotion of human health.

Full textAbstract:
The Green Drop Certification Programme, launched in 2008 alongside the Blue Drop Certification Programme, aims to provide the Department of Water Affairs with a national overview of how municipalities and their individual wastewater treatment works (WWTW) are complying with licence conditions set by the National Water Act (NWA) (No. 36 of 1998; DWAF 1998) and the Water Services Act (No. 108 of 1997; DWAF 1998). By publishing the results of each municipality’s performance, the programme aims to ensure continuous improvement in the wastewater treatment sector through public pressure. The programme has been identified by this project as a necessary linking tool between the NWA and the Water Services Act to ensure protection and sustainable use of South Africa’s natural water resources. It does this through assisting municipalities to improve their wastewater treatment operations which in theory will lead to discharged effluent that is compliant with discharge licence conditions. These discharge licences form part of the NWA’s enforcement tool of Source Directed Controls (SDC) which help a water resource meet the ecological goals set for it as part of Resource Directed Measures (RDM). The link between meeting the required SDC and achieving the RDM goals has never been empirically tested. This project aimed to determine the present ecological condition of the Uie River, a tributary of the Sundays River which the Sundays River Valley Municipality (SRVM) discharges its domestic effluent into. It then determined whether the SRVM’s WWTW was complying with the General Standard licence conditions and what the impact of the effluent on the river was through the analysis of monthly biomonitoring, water chemistry and habitat data. Lastly, the project examined the effectiveness of the Green Drop Certification Programme in bringing about change in the SRVM’s wastewater treatment sector, which previously achieved a Green Drop score of 5.6 percent. It wanted to examine the underlying assumption that a WWTW which improves its Green Drop score will be discharging a better quality effluent that will help a water resource meets the RDM goals set for it. The Kirkwood WWTW did not have a discharge licence at the time of assessment and was thus assessed under the General Standard licence conditions. It was found that the Kirkwood WWTW was not complying with the General Standard discharge licence conditions in the Uie River. This was having a negative impact on the river health, mainly through high concentrations of Total Inorganic Nitrogen (TIN-N), orthophosphate and turbidity. The SRVM should see an improvement in its Green Drop score for the Kirkwood WWTW. However, the municipality showed no implementation of necessary programmes. Implementation of these programmes would help the SRVM meet the General Standard licence conditions (part of SDC) which would help the Uie River meet the RDM goals set for it.

AbstractExtreme climate change events such as frequent and prolonged droughts or floods associated with climate change can be very disruptive to peoples’ livelihoods particularly in rural settings, where people rely on the immediate environment for livelihood. Shocks in the people’s livelihoods can trigger diverse responses that include migration as a coping or adaption strategy. Migration takes many forms depending on the context and resources availability. Very few studies in Kenya have used qualitative analysis to bring up women’s voices in relation to gender, climate change, and migration, especially along hydrological gradient. This chapter presents results of qualitative research conducted from 58 participants in 2018 in three counties in Kenya, namely, Kiambu County, Machakos, and Makueni. The study sought to examine gender perceptions related to climate-induced migration, that is: whether climate change is perceived to be affecting women’s livelihood differently from that of men; examine in what ways experiences of climate induced migration differed for men and women; explore perceptions on the county government efforts to cope with climate-induced migration; and examine perceptions of the role of nongovernmental agencies in helping citizens cope with climate change. From the results obtained on ways in which climate change affected women livelihoods more than men had four themes: (1) women exerted more strain in domestic chores, child/family care, and in the farm labor; (2) women also experienced more time demands. The sources of water and firewood were getting more scarce leading to women travel long distances in search to fetch water and firewood; (3) reduced farm yields, hence inadequate food supply; and (4) the effects of time and strain demands on women was a contributory factor to women poor health and domestic conflicts. Several measures that the county government could take to assist women to cope with climate change-induced migration had five themes which include the following: (1) developing climate change mitigations, and reducing deforestation; (2) increasing water harvesting and storage; (3) develop smart agriculture through the use of drought-resistant crops and drought mitigation education; (4) encourage diversification of livelihoods; and finally (5) providing humanitarian assistance to the most vulnerable populations such as orphans and the very poor. Thirdly, the measures mentioned that NGO’s could take to assist rural communities to cope with climate change-induced migration did not vary significantly from those mentioned for county government, except probably for a new theme of increasing advocacy for climate adaption policies.

Digital health is the intersection of information, computer, and medical science and healthcare, which focusses on adopting information technology (IT) within clinical and healthcare processes. In this chapter, a maturity measurement framework of digital health in China is developed. The framework is applied to contextualize different aspects of the recent progress, opportunities, and challenges of digital health in China; more specifically, to identify its potential in improving the quality and delivery of healthcare (SDG3) and the way health information is shared through new value chains in the health system. The demand of quality education, digital health literacy, and expansion of complementary skills among health professionals, patients, and the general population will become more important to ensure inclusive and equitable education and to promote lifelong learning (SDG4). Transforming health service supply through digitization (automating processes) as well as digitalization (changing to new model of care deliveries) will enable better access in rural regions and help prevent the urban–rural divide faced by many people. Progress in digital health can facilitate equality between populations and reduce inequality among different groups of population by location, health, or economic status (SDG10). This chapter discusses the recent establishment of the Chinese National Health Information Platform, also known as the 4631-2 project, and then takes a system perspective to assess the impacts by covering four dimensions: translation, education, transformation, and technology. Finally, the chapter provides future projections on the basis of the literature synthesis, including opportunities and challenges for a sustainable digital health system in China.

Full textAbstract:
The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the industrial and urban consumers, there is a perennial shortage of power in the agriculture sector. Consequently, there is an emergent need to produce more power in order to fulfil the needs of this sector effectively. One way of accomplishing this is setting up captive, preferably rural based, small power generation plants. In these power plants, instead of water-head, diesel oil or coal, we can use agri-residue to produce electricity. One such power plant (1–2 MW capacity) can satisfy the power need of 25 to 40 nearby villages. The agriwaste like rice straw, sugarcane-trash, coir-pith, peanut shells, wheat stalks & straw, cottonseed, stalks and husk, soyabean stalks, maize stalks & cobs, sorghum. Bagasse, wallnut shells, sunflower seeds, shells, hulls and kernels and coconut husk, wastewood and saw dust can be fruitfully utilized in power generation. This stuff is otherwise a waste and liability and consumes a lot of effort on its disposal; in addition to being a fire and health hazard. Agriwaste stuff which at present is available in abundance and prospects of its utilization in producing energy are enormous. This material can be procured at reasonably low rates from the farmers who will thus be benefited economically, apart from being relieved of the responsibility of its disposal. Agri-residue has traditionally been a major source of heat energy in rural areas in India. It is a valuable fuel even in the sub-urban areas. Inspite of rapid increase in the supply of, access lo and use of fossil fuels, agri-residue is likely to continue to play an important role, in the foreseeable future. Therefore, developing and promoting techno-economically-viable technologies to utilize agri-residue efficiently should be a persuit of high priority. Though there is no authentic data available with regard to the exact quantity of agricultural and agro-industrial residues, its rough estimate has been put at about 350 mt per annum. It is also estimated that the total cattle refuse generated is nearly 250 mt per year. Further, nearly 20% of the total land is under forest cover, which produces approximately 50 mt of fuel wood and with associated forest waste of about 5 mt.(1). Taking into account the utilization of even a portion (say 30%) of this agri-residue & agro-industrial waste as well as energy plantation on one million hectare (mha) of wastelands for power generation through bioenergy technologies, a potential of some 18000 MW of power has been estimated. From the foregoing, it is clear that there is an enormous untapped potential for energy generation from agri-residue. What is required is an immediate and urgent intensification of dedicated efforts in this field, with a view to bringing down the unit energy cost and improving efficiency and reliability of agri-waste production, conversion and utilisation, leading to subsequent saving of fossil fuels for other pressing applications. The new initiatives in national energy policy are most urgently needed to accelerate the social and economic development of the rural areas. It demands a substantial increase in production and consumption of energy for productive purposes. Such initiatives are vital for promoting the goals of sustainability. cleaner production and reduction of long-term risks of environmental pollution and consequent adverse climatic changes in future. A much needed significant social, economic and industrial development has yet to take place in large parts of rural India; be it North, West, East or South. It can be well appreciated that a conscious management of agri-residue, which is otherwise a serious liability of the farmer, through its economic conversion into electric power can offer a reasonably viable solution to our developmental needs. This vision will have to be converted into a reality within a decade or so through dedicated and planned R&D work in this area. There is a shimmering promise that the whole process of harvesting, collection, transport and economic processing and utilisation of agri-waste can be made technically and economically more viable in future. Thus, the foregoing paras amply highlight the value of agri-residue as a prospective source of electric power, particularly for supplementing the main grid during the lean supply periods or peak load hours and also for serving the remote areas in the form of stand-alone units giving a boost to decentralised power supply. This approach and option seems to be positive in view of its potential contribution to our economic and social development. No doubt, this initiative needs to be backed and perused rigorously for removing regional imbalances as well as strengthening National economy. This paper reviews the current situation with regards to generation of agriwaste and its prospects of economic conversion into electrical power, technologies presently available for this purpose, and the problems faced in such efforts. It emphasizes the need for an integrated approach to devise ways and means for generating electrical power from agriwaste; keeping in mind the requirements of cleaner production and environmental protection so that the initiative leads to a total solution.

This paper provides justification for solar-powered electrodialysis desalination systems for rural Indian villages. It is estimated that 11% of India’s 800 million people living in rural areas do not have access to an improved water source. If the source’s quality in regards to biological, chemical, or physical contaminants is also considered, this percentage is even higher. User interviews conducted by the authors and in literature reveal that users judge the quality of their water source based on its aesthetic quality (taste, odor, and temperature). Seventy-three percent of Indian villages rely on groundwater as their primary drinking supply. However, saline groundwater underlies approximately 60% of the land area in India. Desalination is necessary in order to improve the aesthetics of this water (by reducing salinity below the taste threshold) and remove contaminants that cause health risks. Both technical and socioeconomic factors were considered to identify the critical design requirements for inland water desalination in India. An off-grid power system is among those requirements due to the lack of grid access or intermittent supply, problems faced by half of Indian villages. The same regions in India that have high groundwater salinity also have the advantage of high solar potential, making solar a primary candidate. Within the salinity range of groundwater found in inland India, electrodialysis would substantially reduce the energy consumption to desalinate compared to reverse osmosis, which is the standard technology used for village-level systems. This energy savings leads to a smaller solar array required for electrodialysis systems, translating to reduced capital costs.

Abstract Food, energy, and water are the significant factors necessary for the social and economic well-being and prosperity of people, particularly to accelerate rural development. In order to attain sustainable development in off-grid villages, the issues associated with the Food-Energy-Water (FEW) nexus must be addressed with respect to social, economic and environmental aspects. SunMoksha, a socio-technical enterprise, has proposed a model that includes smart technical solutions or intelligent assets, such as, Smart AQUAnet™, Smart Nanogrid™, Smart MEZ™, etc., addressing food, energy and water needs in off-grid villages. Its development model allows for multiple sustainable solutions to be introduced into the rural community, to address specific needs as the community moves up in the development process. In this paper, a method is presented to identify such sustainable smart solutions. The method involves the use of the dilemma triangle and Go/No-Go analysis to address the needs in off-grid Indian villages. We demonstrate the efficacy of the method by first identifying the key issues in an Indian off-grid village from the perspective of the FEW nexus using the dilemma triangle construct. A Go/No-Go analysis is used to select the best feasible solution from a set of possible solutions addressing the dilemmas and issues. Additionally, the needs for sanitation in the village is also considered in the analysis, keeping in mind the health and well-beings of the communities. The method is generic and will support stakeholders/decision-makers in identifying and selecting the best suitable solution from a set of potential solutions. The method is illustrated for an off-grid village to identify an intelligent asset to simultaneously address the sanitation, energy and water needs.

Full textAbstract:
Abstract BB field complex redevelopment is an integrated development under PETRONAS Enhanced Oil Recovery (EOR) project. BB fields are producing fields operated by PETRONAS Carigali Sendirian Berhad (PCSB). The BB fields redevelopment is a project to redevelop both B1 and B2 fields and to enable EOR implementation in the B1 field. The B1 redevelopment includes the EOR implementation through immiscible water alternating gas (IWAG), infill drilling, and safeguarding of no further activity (NFA) production. The B1 redevelopment also incorporates some provisions for the B2 field to secure gas supply for B1 IWAG. The B2 redevelopment focuses on safeguarding B2 NFA production. The redevelopment consists of three main elements, 1) EOR IWAG that involves injector well drilling at a new IWAG injection wellhead platform, 2) infill drilling at existing platforms and 3) safeguarding of NFA. Surface facilities scope includes installing a new Central Processing Platform (CPP) for B1 field, wellhead platforms, and intra-field pipelines. The CPP includes 60 kbpd water injection plant capacity, gas compression, gas-liquid separation, and produced water treatment. Modification in the B2 field is to flow gas from the B2 field to the B1 field. Operational readiness is crucial to ensure that the integrated project is executed smoothly. Two cases for changes are new technology deployment for water injection module (WIM) and people capability. It is a big challenge to achieve an effective start-up with minimum delay. There are some important aspects considered includes operation philosophy, Health Safety and Environment (HSE), and collaborative working environment (CWE) implementation. It is important to ensure improving oil recovery through infill and IWAG. Best practices in operation readiness of an integrated project that have many challenges that include process, people, and technology. These best practices may be replicated in any other projects by other companies/operators.

Full textAbstract:
On February 25, 2009, OCP Ecuador S.A. faced its first incident; an oil spill consisting of 11,700 barrels of heavy crude oil in an area of high biodiversity in eastern Ecuador. An earth movement caused stress in the pipeline causing its breakage. The temporarily impacted area covered 30 hectares of soil and gravel along 180 kilometers of three rivers that form the high watershed of the Amazon River; these rivers are the Santa Rosa, Quijos and the Coca. During the emergency, while workers rallied to contain the spill and clean the affected area, other workers took safety precautions regarding the health of the inhabitants of the area. Consequently, 1,258 residents from the Gonzalo Pizarro and Orellana cantons received medical assistance in order to rule out patients with pathologies related to the oil spill. OCP executed a joint effort with the Emergency Operations Committee (COE) stationed in Coca in order to supply water for the citizens that reside in the affected area. OCP responded to the requirements claimed by residents, all of which were approved by the COE. Communities affected by the event participated in cleaning efforts through the creation of temporary jobs for them. OCP strictly adhered to the regulations passed by the Ministry of the Environment and those of internationally accepted best practices for these types of events. The media and the citizenry were kept continuously abreast of developments. In addition, all corresponding works and reliability tests were performed on March 4 in order to restart pumping activities. On September 30th, 2009, and following a rigorous process of cleaning and remediation (L&Rr—in Spanish) activities, all tasks were completed in all affected areas prior to an inspection and a walking tour of the area performed by governmental authorities, community members and independent observers. For the collective benefit of affected communities, the environment and OCP, local authorities and international auditors recognized the model established during the event. OCP created a taskforce charged with the execution of the Environmental Remediation Program (PRA—in Spanish) and environmental authorities prepared and approved this program. The Environmental Remediation Taskforce (UPRA) covered the following aspects related to the incident: legal, environmental, cleaning and remediation technical aspects, as well as social, environmental, financial, insurance, internal and external communication aspects, along with a rigorous oversight of contractors. The model implemented is the first of its kind deployed in Ecuador. National and international regulations in force validated the methodology used to remediate the soil, riverbanks and surface water contaminated with the oil caused by the incident. The application of this methodology, aptly deployed in response to the distress situation present at the various affected areas, allowed a reduction in a short period, of the total hydrocarbon concentrations established in the environmental standard, to equal or lower values than those previously indicated for sensitive ecosystems. OCP developed and implemented a technical, environmental and economic matrix that allowed the Company to choose and justify the remediation methods used in affected areas.

Full textAbstract:
In the past 40 years, China has experienced the largest and fastest urbanization development in the world. The infrastructure, urban environment and medical services of cities have been improved significantly. The health impacts are manifested in the decrease of the incidence of infectious diseases and the significant increase of the life span of residents. However, the development of urbanization in China has also created many problems, including the increasing pollution of urban environment such as air, water and soil, the disorderly spread of urban construction land, the fragmentation of natural ecological environment, dense population, traffic congestion and so on. With the process of urbanization and motorization, the lifestyle of urban population has changed, and the disease spectrum and the sequence of death causes have changed. Chronic noncommunicable diseases have replaced acute infectious diseases and become the primary threat to urban public health. According to the data published by the famous medical journal The LANCET on China's health care, the economic losses caused by five major non-communicable diseases (ischemic heart disease, cerebrovascular disease, diabetes mellitus, breast cancer and chronic obstructive pulmonary disease) will reach US$23 trillion between 2012 and 2030, more than twice the total GDP of China in 2015 (US$11.7 trillion). Therefore, China proposes to implement the strategy of "Healthy China" and develop the policy of "integrating health into ten thousand strategies". Integrate health into the whole process of urban and rural planning, construction and governance to form a healthy, equitable and accessible production and living environment. China is building healthy cities through the above four strategies. The main strategies from national system design to local planning are as follows. First of all, the top-level design of the country. There are two main points: one point, the formulation of the Healthy China 2030 Plan determines the first batch of 38 pilot healthy cities and practices the strategy of healthy city planning; the other point, formulate and implement the national health city policy and issue the National Healthy City. The evaluation index system evaluates the development of local work from five aspects: environment, society, service, crowd and culture, finds out the weak links in the work in time, and constantly improves the quality of healthy city construction. Secondly, the reform of territorial spatial planning. In order to adapt to the rapid development of urbanization, China urban plan promote the reform of spatial planning system, change the layout of spatial planning into the fine management of space, and promote the sustainable development of cities. To delimit the boundary line of urban development and the red line of urban ecological protection and limit the disorderly spread of urban development as the requirements of space control. The bottom line of urban environmental quality and resource utilization are studied as capacity control and environmental access requirements. The grid management of urban built environment and natural environment is carried out, and the hierarchical and classified management unit is determined. Thirdly, the practice of special planning for local health and medical distribution facilities. In order to embody the equity of health services, including health equity, equity of health services utilization and equity of health resources distribution. For the elderly population, vulnerable groups and patients with chronic diseases, the layout of community health care facilities and intelligent medical treatment are combined to facilitate the "last kilometer" service of health care. Finally, urban repair and ecological restoration design are carried out. From the perspective of people-oriented, on the basis of studying the comfortable construction of urban physical environment, human behavior and the characteristics of human needs, to tackle "urban diseases" and make up for "urban shortboard". China is building healthy cities through the above four strategies. Committed to the realization of a constantly developing natural and social environment, and can continue to expand social resources, so that people can enjoy life and give full play to their potential to support each other in the city.

Full textAbstract:
Abstract The Petroleum Working Group (PWG) of the United Nations Economic Commission for Europe (UNECE) has developed the Petroleum Resource Specifications and Guidelines (PRSG) to facilitate the application of the United Nations Framework Classification for Resources (UNFC) for evaluating and classifying petroleum projects. The UNFC was developed by the Expert Group on Resource Management (EGRM) and covers all resource sectors such as minerals, petroleum, renewable energy, nuclear resources, injection projects, anthropogenic resources and groundwater. It has a unique three- dimensional structure to describe environmental, social and economic viability (E-axis), technical feasibility and maturity (F-axis) and degree of confidence in the resource estimates (G-axis). The UNFC is fully aligned to holistic and sustainable resource management called for by the 2030 Agenda for Sustainable Development (2030 Agenda). UNFC can be used by governments for integrated energy planning, companies for developing business models and the investors in decision making. Internationally, all classification systems and their application continue to evolve to incorporate the latest technical understanding and usage and societal, government and regulatory expectations. The PRSG incorporates key elements from current global petroleum classification systems. Furthermore, it provides a forward-thinking approach to including aspects of integrity and ethics. It expands on the unique differentiator of the UNFC to integrate social and environmental issues in the project evaluation. Several case studies have been carried out (in China, Kuwait, Mexico, Russia, and Uganda) using UNFC. Specifically, PRSG assists in identifying critical social and environmental issues to support their resolution and development sustainably. These issues may be unique to the country, location and projects and mapped using a risk matrix. This may support the development of a road map to resolve potential impediments to project sanction. The release of the PRSG comes at a time of global economic volatility on a national and international level due to the ongoing impact and management of COVID-19, petroleum supply and demand uncertainty and competing national and international interests. Sustainable energy is not only required for industries but for all other social development. It is essential for private sector development, productive capacity building and expansion of trade. It has strong linkages to climate action, health, education, water, food security and woman empowerment. Moreover, enduring complex system considerations in balancing the energy trilemma of reliable supply, affordability, equity, and social and environmental responsibility remain. These overarching conditions make it even more essential to ensure projects are evaluated in a competent, ethical and transparent manner. While considering all the risks, it is also critical to reinforce the positive contribution a natural resource utilization project provides to society. Such an inquiry can focus on how the project contributes to the quality of life, environment, and the economy – the people, planet, and prosperity triad. Such an approach allows consistent, robust and sustainable investment decision making and energy policy development.
