Abstract:

Abstract: One of the severe issues that is well recognized on the planet is the water scarcity. Overexploitation of groundwater and surface water resources is the outcome of population growth, urbanization, and industrial expansion. Due to uneven rainfall, the traditional water sources, such as wells, rivers, and reservoirs, are unable to supply all of the water needed .While a new water source is being investigated by the rainwater gathering system. Utilizing rainwater is the study goal, which is closely related to the idea of protecting the environment. This study examines the Rain Water Harvesting (RWH) system as a substitute for the BBDITM H-block as a source of water. By taking into account nearly all technological aspects, the development system satisfies social requirements and maybe implemented in both urban & rural areas.

Abstract:

Abstract The urban water problem has become one of the most significant problems hindering sustainable urban development. Rainwater harvesting and utilization is a green solution to alleviate the urban water problem. However, existing urban rainwater management pays more attention to flood control and lacks systematic planning for rainwater harvesting in China. In this paper, the calculation methods of rainwater harvesting potential are investigated, and the difference of rainwater harvesting system between the traditional model and sponge model is compared based on the rainwater harvesting mechanism. In addition, the study progress of four representative rainwater harvesting measures (green roofs, bioretention ponds, infiltration wells, and rainwater tanks) is reviewed and four representative optimization tools are listed. Moreover, we summarized the challenge of rainwater harvesting and provided recommendations for future research on the rainwater harvesting system. This review aims to provide theoretical support for the comprehensive utilization of urban rainwater resources to promote the sustainable development of cities.

Abstract:

Climate change and geographic location affect water availability. Coastal areas in Indonesia generally have drinking water problems because the well water is dry due to the dry season and the water is brackish, as is the case in Sawojajar Village in Brebes Regency, Central Java. On the other hand, the potential for rainwater in Sawojajar Village is quite good. The Brebes Regency Government is planning and implementing a rain harvesting (Gama Rain Filter) with an individual type for people who want to install rainwater harvestings in their homes, and a communal type for people who still want communal rainwater harvestings. This applied research aims to compare the two types. The individual type planning method for harvesting rain is carried out in each house and the communal type planning method is carried out in groups of houses. The planning carried out includes checking the quality and quantity of rainwater, calculating the dimensions of the storage tank, design drawings, and planning and implementation budget plans. The results of this applied research are the quality and quantity of rainwater, the design of individual and communal type rainwater harvestings, and the planning costs and implementation costs required. This research resulted in the conclusion that the individual type rain harvesting is more recommended than the communal type because the individual type costs less to plan and construct, is more flexible in placement, easier to manufacture, and maintains operations more securely.

Abstract:

The overall objective of this study is to evaluate the possibility of promotion of rooftop rainwater harvesting in addressing even increasing water scarcity in Kathmandu, Lalitpur and Madhyapur Thimi municipalities. Fifty respondents were taken for questionnaire survey for each municipality. The questionnaire was distributed among friends, relatives, school teachers, publics in hospital and environment exhibitions. They were requested to fill up the questionnaire. Cases of organizations, schools and residences were studied where the rainwater harvesting systems were installed. Interview schedule was carried out with the owner of the houses/schools/organizations where the system was installed. Out of fifty respondents in Kathmandu Metropolitan City, 90% respondents are willing to know about rainwater harvesting system. 52 % respondents already knew about modern rainwater harvesting system. Out of 50 respondents in Lalitpur Metropolitan City, 100% respondents are willing to know about rainwater harvesting system. 52% respondents already know about modern rainwater harvesting system. Out of 50 respondents in Madhyapur Thimi Municipality, 100% respondents are willing to know about rainwater harvesting system. 32% respondents already know about modern rainwater harvesting system. The overall domestic reduction in demand for Kathmandu valley is found to be 24.09% and the overall institutional reduction in demand for Kathmandu valley is found to be 23.99% which indicates that rainwater harvesting system plays an immense role to reduce water demand to some extent. So, there must be massive campaign to motivate people to install rainwater harvesting systems as we are suffering from maximum water scarcity nowadays. This system can replenish the demands of millions of people of Kathmandu valley. If people start using rainwater harvesting system, then the demand of the people will be fulfilled by rainwater. People will feel relief to some extent. They will be free from paying huge bills for tankers every month because rainwater harvesting system is one time investment. So, it proves to be economical in long run as well. So we must start using rainwater harvesting system for fulfilling our great water demand.

Abstract:

The problems that commonly occurred in the field of water resources were the lack of clean water in the dry season and excess water in the wet season. Those problems may impact on efforts to fulfil the need for clean water. One of the efforts that can be used to overcome those problems is rainwater harvesting. The purpose of this research was to design a rainwater harvesting system to fulfil the need for clean water during the dry season and groundwater conservation in the wet season. The design of the system includes the roof of the rainwater harvesting building, rainwater harvesting reservoirs, infiltration wells, and rainwater quality treatment equipment. The roof of the rainwater harvesting building was designed with a size of 6.50 m x 5.00 m. The runoff discharge from the roof is 1,084.02 liters/hour. The available rainwater harvesting reservoir has a capacity of 5,300 liters. There were 2 units of infiltration wells that function to absorb abundant rainwater from rainwater harvesting reservoirs, each well is 0.80 m in diameter and 1.35 m deep. Utilization of water from rainwater harvesting reservoirs can be done after going through the process in rainwater quality treatment equipment. The results of this activity can be recommended for widespread application.

Abstract:

Rainwater harvesting to irrigate small-scale gardens enhances food self-sufficiency to overcome rural poverty. So far rainwater harvesting is not encouraged by the Namibian National Water Supply and Sanitation Policy nor supported financially by the Namibian government. This study proposes two rainwater harvesting facilities to irrigate gardens; one collects rain from household roofs with tank storage, the second collects rain on a pond roof with pond storage. The aim of this paper is to assess the benefits of rainwater harvesting-based gardening and to propose policy and financing implications for the Namibian government. We investigate the benefits of rainwater harvesting through a literature review, a cost–benefit analysis, monitoring of project pilot plants and a comparison with the existing irrigation and drinking water infrastructure. The results indicate that rainwater harvesting offers numerous benefits in technological, economic, environmental and social terms. The facilities have a positive net present value under favourable circumstances. However, material investment costs pose a financing problem. We recommend that government fund the rainwater harvesting infrastructure and finance privately garden and operation and maintenance costs. Integrating these aspects into a national rainwater harvesting policy would create the conditions to achieve the benefits of an up-scale of rainwater harvesting based gardening in Namibia.

Abstract:

El aprovechamiento de agua de lluvia, a pesar de ser una antigua técnica para recoger escorrentía para uso doméstico, agricultura y gestión ambiental, no tiene una amplia aplicación. Potencialmente, los sistemas de aprovechamiento de agua de lluvia (RWH) pueden jugar un papel clave en el abastecimiento de la demanda de agua urbana como una alternativa a las tecnologías convencionales de tratamiento de agua como son la desalinización y otras tecnologías costosas Esta tesis doctoral pretende encontrar las configuraciones de RWH más eficientes, primero cuantificando el consumo de recursos e impactos ambientales asociados con RWH en áreas urbanas, y, después, estudiando las diferentes configuraciones para abastecimiento doméstico considerando condiciones climáticas mediterráneas y desérticas. La investigación está motivada por el incremento en la necesidad de encontrar medidas correctoras y preventivas que ayuden a gestionar los problemas de abastecimiento de agua, especialmente considerando los efectos del cambio climático en el área mediterránea y los del abastecimiento de agua en las zonas áridas. En línea con este planteamiento, la hipótesis se basa en el hecho de que el agua pluvial es agua blanda y, por lo tanto, requiere menos detergente y aditivos suavizantes. De ahí que represente un sustituto ventajoso para el agua utilizada en lavandería, especialmente en lugares donde el agua de grifo presenta altos niveles de dureza, así como cuando la disponibilidad de agua es limitada. Para analizar las diferentes configuraciones de RWH, se aplicaron las siguientes metodologías: análisis de exergía y análisis de eficiencia exergética para determinar el consumo de recursos y eficiencia; análisis de ciclo de vida (LCA) para identificar los impactos ambientales; análisis de coste de ciclo de vida (LCC) para encontrar la viabilidad económica, y análisis envolvente de datos (DEA) para identificar la frontera de mejores-prácticas hacia la sostenibilidad. En general, los resultados evidencian que configuraciones en clúster son más eficientes en el uso de recursos que las individuales, en términos exergéticos y económicos. Se encontró que los impactos ambientales son inversamente proporcionales al incremento en el abastecimiento de agua de lluvia. Los escenarios de mejores prácticas son mayoritariamente dependientes al área de recogida. Asimismo, los ahorros en el consumo de aditivos de lavandería resultan en una mejor conducta ambiental y económica en zonas con alta dureza en agua de grifo.<br>Rainwater harvesting, though is an ancient technique to collect run-off rainwater for domestic water supply, agriculture and environmental management, it is not widely applied. Rainwater harvesting (RWH) systems could potentially play a key role in helping cities meet their water demand, as an alternative to conventional water treatment technologies such as desalination and other costly technologies. This doctoral thesis aims to find the most efficient configuration of RWH, first by quantifying the resource consumption and environmental impacts associated to RWH in urban areas and then studying different configurations for domestic water supply considering Mediterranean and desert climate conditions. The query is motivated by the increasing necessity to find preventive and corrective measures that help cope with water supply problems, especially considering climate change effects in the Mediterranean area and water supply problems in arid areas. Along with this, the hypothesis is based on the fact that rainwater is soft water, thus, requires less detergent and softener additives. Therefore, it represents an advantageous substitute for water used for laundry, especially where tap water presents high levels of water hardness and also whenever water availability is limited. To analyze the different RWH configurations, the following methodologies were applied: exergy analysis and exergetic efficiency analysis to find resource consumption and efficiency; life cycle assessment (LCA) to identify environmental impacts; life cycle costing (LCC) to find economic feasibility and; data envelopment analysis (DEA) to identify best-practice frontier towards sustainability. The results evidence that generally cluster configurations are more resource efficient than those in individual configurations, in exergetic and economic aspects. Environmental impacts were found to be inversely proportional to the increase in rainwater supply. Best-practice scenarios were found mostly dependent on the area of rainwater collection. Furthermore, savings from laundry additive consumption result in much improved economic and environmental performances in areas with hard tap water.

Abstract:

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2009.<br>Includes bibliographical references (leaves 93-96).<br>This study assesses the current state of rainwater harvesting in the Northern Region of Ghana and makes recommendations regarding if and how rainwater harvesting could be used to address Pure Home Water's goal of reaching 1 million people in the next five years with safe drinking water. Three principal aspects of the water supply are considered: quality, quantity, and cost. Bacteriological water quality is tested to determine the level of risk. Rainwater supplies ranged from low (1 to 10 E.coli CFU/100ml) to intermediate risk (10 to 99 E. coli CFU/100ml.) Time-based reliability is simulated using a simulation model in Microsoft Excel. Reliability ranges from five percent to ninety-nine percent. Unit cost per cubic meter is calculated for surveyed rainwater harvesting systems in Northern Ghana. The unit cost of water from these designs ranged between approximately $1/m3 and $10/m3. Storage-reliability-yield relationship is developed and graphed for the Northern Region. This curve is useful for properly sizing rainwater harvesting systems. The use of a filter to post-treat rainwater before consumption is recommended, both for use with the rainwater, but also for provision of safe water when the users rely on a supplementary unimproved source, usually a dugout or dug well, for water supply. The feasibility of low-cost underground storage should be investigated. The geology and soil conditions in the Tamale region might provide a suitable match for a cheaper storage mechanism using plastic tarps and constructed pits.<br>(cont.) If the cost of storage could be lowered, rainwater harvesting could contribute in a larger way to Pure Home Water's mission and reach more people. Do-it-yourself rainwater harvesting in the Northern Region of Ghana is a fairly widespread. Finding ways to improve the quantity and quality of informal harvesting is a potential means for improving water supply for many low income households in the Northern Region. Currently, rainwater harvesting presents an opportunity to extend water supply to rural dwellers where few other alternatives are available.<br>by David Allen Barnes.<br>M.Eng.

Dissertação apresentada para a obtenção do grau de Mestre em Engenharia do Ambiente, Perfil Engenharia Sanitária<br>With increasing pressure on the environment, particularly on water resources, due to outside forces such as climate change and population growth, water is nowadays a scarce and a valuable resource. With the need to find new alternatives, rainwater harvesting should be seen as an important strategy for better management of water resources, once it constitutes a free source of potable water. Rainwater harvesting systems, which already have a global implementation, are a recognised way for urban buildings to reduce their reliance on the public mains supply. Its applications are predominantly non-potable, namely toilet flushing and gardening. The aim of this report is to produce a comprehensive assessment of rainwater harvesting and its potential use all over the world, as well as the potential economical and environmental benefits. It is provided a description of all the rainwater harvesting system components, as well as water quality requirements according to the water final purpose. A case study is presented, which main object is to evaluate the feasibility of rainwater harvesting for gardening, applied to the University Campus of the Faculty of Sciences and Technology of Universidade Nova, Lisbon (FCT/UNL). A detailed characterization of the existing irrigation system on campus is provided, as well as its potential ability to collect rainwater. According to the supply and demand balance, several scenarios are presented in order to provide the necessary information for the decision-makers to evaluate the best solution for the desired application. For such, all the available information was analyzed, in order to determine the environmental, technical and economical viability of the project.

Abstract:

Rainwater harvesting (RWH) in the UK has seen a low level of uptake relative to similar settings such as Australia and Germany. The relatively low cost of municipal water in the UK limits the financial savings associated with RWH systems, especially in a domestic setting. Although financial benefits can be relatively low (in terms of reduced water bills), academic and practitioner studies have demonstrated the potential for RWH to significantly reduce potable water demands at typical UK houses. Hence, increased uptake of RWH has potential to contribute to mitigating droughts in water scarce regions. Stormwater management in the UK is receiving increasing attention at all levels; from grass-roots sustainable drainage systems (SuDS) such as downpipe disconnections and raingardens; through to implementation of urban realm attenuation schemes and continued development of guidance from UK policy makers. The public realm nature of most SuDS presents a need for partnership approaches to be fostered between infrastructure mangers and the general public. The application of RWH as a technology within the SuDS management train has been limited in the UK as policy makers have taken the view that RWH tanks may be full at the start of a design storm, and thus the potential for attenuation and peak discharge reduction has been largely ignored. However, in the last few years there has been a shift in emphasis; from RWH perceived purely as a water demand management technology to a focus on its wider benefits e.g. mitigating surface water flooding through improved stormwater management. RWH systems examined in this thesis are now available which offer multiple benefits to both end-users and water service providers. The application of RWH in a dual purpose configuration (to displace potable water demands and control stormwater discharges) has seen increasing interest during the development of this thesis. However, the successful design of RWH as a stormwater management tool requires a series of calculations to be completed. To date, practitioners have frequently relied upon low-resolution heuristic methods which lead to a small range of configurations being deployed, with minimal demonstrable stormwater control benefits. In this thesis, full details of novel and traditional RWH technologies were identified and described. Empirical data was collected, both in laboratory conditions and at field sites, to identify the real world operating characteristics of a range of RWH configurations. Additionally a new time series evaluation methodology was developed to enable RWH systems to be designed and analysed. This method quantifies water demand benefits and also focusses on stormwater management metrics (i.e. largest annual discharge and total discharge volume per year). The method was developed to enable a range of RWH configurations to be evaluated at a given site. In addition, a decision support tool (RainWET) was developed and tested which enabled the methods to be deployed in real world settings. The application of the RainWET software allowed a UK-wide, time series analysis of RWH configurations to be completed and the holistic benefits of a range of dual purpose RWH systems to be analysed and described. Evidence from the UK study suggests that a traditional RWH installation (3000l storage, 300l/day demand and 60m2 roof) installed at a house in a water scarce region (London, SAAR 597mm) was able to fully mitigate stormwater overflows over a 20 year analysis whilst providing a mean water saving of 31,255l/annum. An equivalent system located in the wettest region studied (Truro, SAAR 1099mm) saw mean reductions in the largest annual storm of 62% (range 35-86%) whilst satisfying a mean rainwater demand of 50,912l/annum. The study concluded that suitably designed dual purpose RWH systems offered better stormwater management benefits than those designed without a stormwater control device. In addition, the integration of smart RWH controls were shown to maximise stormwater control benefits with little or no reduction in a system’s ability to satisfy non-potable water demands.

Abstract:

Rainfall in semi-arid areas is generally insufficient to meet crop water requirements, and above all erratic in distribution. This leads to crop yield fluctuation, which drastically affects food security. Rainwater harvesting technologies have been implemented in these areas in order to mitigate the effect of perennial droughts. The successful adoption of these technologies can contribute to poverty alleviation, and therefore improve the livelihood of resource-poor subsistence farmers. Field trials for testing different rainwater harvesting scenarios are expensive, time consuming and laborious. As a result, crop models must be used to help study these systems, and thereby make prudent water harvesting design choices for specific situations. For this purpose, a simple, one-dimensional soil water balance model (Soil Water Balance-SWB) was modified by incorporating linear runoff estimation models in order to predict the soil water balance and crop yield under different rainwater harvesting design scenarios and to select the design most likely to succeed in a particular locality. Field data collected during the 2007/2008 maize growing season, on sandy clay loam soils, at the Hatfield Experimental Farm of the University of Pretoria, was used to parameterize the different runoff models and to calibrate the SWB crop model. Various rainwater harvesting design scenarios were run for two different semi-arid areas, on different soil types to illustrate the application of the SWB model as a tool to help design the most appropriate rainwater harvesting strategy, taking into account whether arable land is limiting or not limiting for crop production. The SWB model was successfully calibrated. Simulation results reveal that in drier years bigger design ratios (cropping area: runoff area) of the in-field rainwater harvesting technique (IRWH) are most likely to be successful, while in wetter years smaller design ratios of the IRWH technique or even simpler rainwater harvesting strategies such as the tied ridge and the conventional tillage techniques can harvest sufficient rainfall for maximum crop production. Results from field trials conducted in Pretoria, on sandy clay loam soils, confirmed that, in a wet season, maize yield is maximized by a smaller IRWH design (1:1B). The SWB model can be used as a tool to help selecting the most appropriate rainwater harvesting strategy under specific conditions with minimum input requirements.<br>Dissertation (MSc)--University of Pretoria, 2011.<br>Plant Production and Soil Science<br>unrestricted

Abstract:

Thesis (M.Sc.(Agronomy)) --University of Limpopo, 2015<br>The changes in climate, especially poor rainfall patterns and distributions are key issues posing major agricultural challenges for food security and threaten the rural livelihoods of many communities in the Limpopo Province. Rainfall (P) is low and limited. These limited P is mostly lost through runoff and evaporation, which result in low soil moisture availability and possible crop failure. Therefore, techniques that reduce these water losses are important for improving dryland crop production and rainwater productivity (RWP). The objectives of this study were to determine the potential and effectiveness of rainwater harvesting and conservation techniques (RWH&CT’s) to conserve and improve plant available water (PAW) for dryland maize production and also determine the efficiency of the RWH&CT’s to improve dryland maize yield and RWP compared to conventional tillage (CON). The study was conducted over a period of two growing seasons (2008/09; 2009/10) using maize as indicator crop at the Towoomba Research Station of the Limpopo Department of Agriculture in the Limpopo Province of South Africa, on an Arcadia ecotope. The experiment was laid out in a randomized complete block design, with four replications and five treatments. The five treatments used in the study were; conventional tillage (CON), No-till (NT), In-field rainwater harvesting (IRWH), Mechanized basins (MB) and Daling plough (DAL). The IRWH and DL were classified as rainwater harvesting techniques (RWHT’s), whilst MB and NT were classified as water conservation techniques. Two access tubes were installed at each treatment to measure the soil water content (SWC) at four different soil depths of 150, 450, 750 and 1050 mm using the neutron water meter. The data collected included climatic data, soil and plant parameters. The data were subjected to analysis of variance through NCSS 2000 Statistical System for Windows and GENSTAT 14th edition. Mean separation tests were computed using Fisher's protected least significant difference test. The SWC of IRWH, DAL and MB were about 510 and 490 mm higher compared to CON and NT treatment during the 2008/09 and 2009/10 seasons, respectively. The PAWT of the IRWH, MB and DAL was significantly different from the CON treatment during the 2008/09 season. For both seasons the biomass yield of the IRWH treatment was significantly different from the NT treatment, producing 23 and 50% more biomass in the 2008/09 and 2009/10 growing seasons, respectively. The grain yield under IRWH was significantly different from the NT treatment during both 2008/09 and 2009/10 seasons. The highest maize grain yield of IRWH was achieved during the 2009/10 season with 56% higher grain yield than the NT treatment. RWP from various RWHT’s were significantly different from the NT treatment. These results indicate that IRWH and DAL were 12 and 2% more effective in converting rainwater into harvestable grain yield than the CON treatment. R2 values of 68.6 and 78.4% for SWC and transpiration (Ev) were obtained when correlated with maize grain yield respectively. This indicates the importance of moisture conservation for improved dryland maize production under low P areas. Therefore, the use of appropriate RWHT’s by smallscale farmers maybe crucial to improve dryland maize production. IRWH outperformed all other treatments in terms of the soil parameters and plant parameter measured during the period of this study. Therefore, these results suggest IRWH has potential of sustaining maize yields under low rainfall conditions. Key words: Rainwater harvesting, conservation techniques, ecotope, rainwater productivity, maize yield, precipitation use efficiency.

Abstract:

In many developing countries, the stress of rapidly growing populations, mismanagement of resources and changing climate has created a burden on already compromised water resources. In Africa, where a significant proportion of the population is without access to improved water source, the urgency for clean available water sources to sustain healthy and productive human and natural populations has become a priority. As a water scarce country, Kenya has seen an increased investment in rainwater harvesting (RWH) projects to harness the vastly untapped rainwater resource, particularly in rural areas. Most of RWH literature is centered on the potential and implementation of rainwater harvesting systems, however not much focus has been placed on examining the demand satisfaction of these systems. This study investigates the reliability of rooftop rainwater harvesting (RRWH) as a key priority source of water supply for domestic use in three towns in Western Kenya: Kisumu, Nakuru and Lodwar. This was done using two approaches (1) the fraction of time water was available and (2) the fraction of time that a minimum demand was met, with acceptable reliability of 0.95 or higher. Actual rainfall data and RRWH parameters were used to produce supply/demand simulations of the system under Constant-Demand and Responsive-Demand scenarios over ten years. It was observed that all towns achieved acceptable reliability values for RRWH in terms of water availability however Lodwar only achieved demand satisfaction below 0.95. This study concluded that though RRWH cannot satisfy the minimum demand requirement through all days of the year, it is more than able to provide an alternative water supply for the domestic household in periods of long dry spells or when primary water source are inadequate.

Abstract:

Explore the possibilities, difficulties, and benefits of large scale rainwater harvesting using recycled water distribution systems. This paper explores the growing use of recycled water and the possibilities that distribution systems have created. It investigates water quality of rainwater harvesting (RWH) systems and the quality of recycled water and their uses. It examines the amount of rain water available using aproximatly 10% of available roof area in the city and examines the benefits of large scale rainwater harvesting unique to San Antonio. An exhaustive search of published materials was conducted, coupled with communications with the Texas Water Development Board and the San Antonio Water System. Quality standards for recycled water were compared with known test results for harvested rainwater. With the use of mathematical models, a distributed rainwater harvesting systems was compared to a stand alone system. Connection to a distribution system reduces the cost of rainwater harvesting by eliminating the need for large amounts of storage, which can account for 50% of the total costs of a standalone system. With minor filtering and periodic quality checks, large structures may supply sufficient amounts of rainwater to justify being a source of water in a recycled water distribution system.

Abstract:

This case study documents experiences from a 10-year project working with a remote island community along the Furo Grande tributary, just off the coast of Belem in the Amazonian region of Brazil. The residents living along Furo Grande experience extreme poverty and social marginalisation, and mainly use latrines which empty directly into the river, or defecate in the forest, which is dangerous particularly for women and girls at night. Successful programme interventions included community engagement and collaborative processes to build trust and relationships with the people, and enable development of designs that respected local cultures, beliefs and routines of the traditional population. Adaptations included development of ecological toilets and rainwater harvesting systems, redesigning the structure to ensure suitability for high tides and flooding, changes to materials, for example the type of wood to prevent rotting, and adaptations to the construction process to utilise local building techniques. Ongoing monitoring enabled challenges to be identified and rectified, and provision of support to communities to strengthen understanding on how to maintain the new facilities.

Full text

Abstract:

Given knowledge gaps on nature-based solutions (NBS), infectious disease and urbanization, researchers sought to investigate the drivers of infectious disease in a developing city context, the differentiated hazards faced by different groups such as Indigenous and peri-urban communities, and the potential of NBS to reduce hazards while providing ecological and social co-benefits. Key messages In Bharatpur, Nepal, the project survey found one in five households had been affected in the past five years by the mosquito-borne disease dengue fever (18.4%). Skin infections were the second most reported infectious disease, affecting 11.5% of households. Proximity to garbage disposal sites was found to be associated with incidence of both dengue and skin infections, and lack of adequate sanitation and clean water is a hypothesized driver for skin infections. Nature-based solutions (NBS) have potential to reduce hazard from infectious disease through filtering water, mitigating flooding and reducing urban temperatures. Local actors participating in project workshops were particularly interested in applying green streets and rainwater harvesting in Bharatpur. Strengthening solid waste management is recommended as a priority action to reduce hazard from dengue, by increasing collection frequency and ensuring city-wide provision of municipal collection services. Improving piped water supply to peri-urban areas is recommended as a priority action to improve hygiene, reduce skin infections and address critical health inequities among vulnerable populations. The study emphasizes that to improve public health outcomes from infectious disease, NBS cannot substitute for basic urban infrastructure and services.
