Abstract:
Some ten years ago, South Africa's newly elected government inherited huge services backlogs with respect to access to water supply and sanitation. About 15 million people were without safe water supply and over 20 million without adequate sanitation services. Since then, the country has made remarkable progress with regard to accelerating the pace of services provision and restructuring and refocusing the entire water sector. Having ensured access to an additional population of over 10 million people, South Africa is well on track to wipe out the infrastructure backlog for basic water supply by 2008, exceeding the Millennium Development Goals (MDG) target. But first, with respect to sanitation for which the national target is universal access to a functioning facility by 2010, the picture is somewhat different. Second, substantial challenges remain in addressing historical inequalities in access to both water supply and sanitation, and in sustaining service provision over the long term.

Abstract:
The Draft Second National Water Resources Strategy of South Africa, which has been published for comment, has identified the implementation of water use efficiency, conservation and water demand management as a core strategy to ensure sufficient water to meet South Africa's needs going into the future. This, ‘non-negotiable performance area’, it says, must be implemented immediately in all water use sectors, specifically municipalities. ‘In view of water scarcity, it is essential that such water losses must be curtailed, especially in terms of the need to provide for the growing water demands of new socioeconomic development’, the strategy points out. While South Africa's non-revenue water levels compare well internationally, as a water scarce country it needs to do all it can to prevent the unnecessary loss of water. This is one of the main recommendations of a recent study into the state of non-revenue water in South Africa commissioned by the Water Research Commission (WRC). To improve the current situation, the water sector must have a clear indication of the current status of non-revenue water in South African municipalities, more specifically what the actual water losses are and how they are split between physical leakage (real losses) and commercial losses (apparent losses). It is for this reason that the WRC, in collaboration with the Department of Water Affairs, launched the latest investigation into the state of non-revenue water in South Africa, which has now been published. In the most comprehensive and detailed study of its kind, to date, data were gathered from 132 municipalities throughout South Africa representing over 75% of the total volume of municipal water supply. The study follows on from similar WRC assessments undertaken in 2001, 2005 and 2007. This is the first time the country has a single, representative estimate of non-revenue water as opposed to various estimates in previous years. The paper shares in more detail findings from this study which have highlighted on average 38% non-revenue water and provide a deeper insight into the problems and challenges faced in tackling water losses in South Africa.

Abstract:
Consistent access to potable water remains a major challenge among communities in rural areas of Vhembe District Municipality (VDM). This is due to the high frequency of water supply infrastructure breakdown due to obsolete infrastructure and inadequate involvement and participation of rural communities in paying for water and maintenance which affect sustainability of water supply system in VDM. This study assesses current state of water supply, challenges and effectiveness of measures in place in order to propose intervention to improve rural water supply system in VDM. The study followed a mixed method research design, which include both qualitative and quantitative methods. Data was analysed using thematic content analysis and chi-square test. The study established that water is inconsistently supplied in VDM. As about 53.5% of the respondents received water once per week which necessitate intervention to improve the situation. All the respondents from the four local municipalities of Vhembe District were not satisfied with the quantity of water received and distance travelled to collect water. The study recommend intervention strategy which included that local management structure to be established and terms of reference agreed with communities including more water supply sources options to be added

Abstract:
The burden of water-related disease is closely related to both the socio-economic situation and public health issues like access to clean water, sanitation and hygiene services. Poverty eradication, through improved access to water and sanitation, is the South African government's major priority. This is partly achieved through subsidising the cost of water and sanitation provision to the poor in rural areas. Whilst the new policies have made a remarkable impact on improved access to water and sanitation services, a general problem since the new approach in 1994 has been the lack of integration of policies for water and sanitation and health. This paper analyses the policies concerning rural water supply and sanitation in South Africa. It considers the structure of institutions, the division of responsibilities and legislated and financial capacity of the South Africa's water sector. A more integrated approach for the policies aiming at water access, sanitation and health is needed. In addition, as the local government's capacity to implement different programmes is limited, a review of the financing system is necessary.

Abstract:
The Covid-19 pandemic has highlighted the importance of hydropolitics in South Africa. The country remains one of the driest countries in the world with a below average rainfall of 450 mm per annum. The country’s economic hub in the Gauteng province is largely dependent on water from the neighbouring Kingdom of Lesotho. On a geopolitical level the country also shares various water sources with neighbouring states. This is especially relevant due to the dependence on South Africa, as the regional hegemon, for access to markets and income. However, large areas of South Africa experience extreme water scarcity due to a combination of factors that include climate change related drought, urbanisation and government-related water management failures. In many local government municipalities across the country the lack of government capacity to supply water resources and manage waste water have reached crisis proportions. Many towns and communities across South Africa have been left with unreliable access to sustainable water resources. This is mainly due to a combination of corruption, poor management and the lack of institutional capacity at local government level. The institutional incapacity of government is a result of the governing party African National Congress’ ideological approach to government, combined with political factionalism, which has stripped the civil service of expertise and led to the exodus of skilled individuals from both government and the country. The government’s implementation of the communist ? based Leninist democratic centralism, commonly known as a cadre deployment strategy, has resulted in large scale state capture and corruption that has had a devastating impact on the delivery of basic services such as water. Hydropolitical civil unrest has increased to an extent that, in instances such as the Majakeng and Maluti-a-Phofung municipalities, unrest became extremely violent and disrupted businesses and well as state education and health facilities. This article is an ontological investigation into the hydropolitical impact of, and ideological reasons for, state incapacity to manage water resources and deliver safe and sustainable supply of water to the population. While reference will be made to the general situation in the country, the Majakeng and Maluti-a-Phofung municipalities will be used as a case studies for the impact of water insecurity on political stability. On the other hand, the City of Cape Town’s ability to manage water scarcity and avert a drought related “day zero” scenario is used as an example of what can be achieved through sound management. The article will combine ideological considerations with theoretical explanations of ideology and state failure within a hydropolitical context in order to explain the current water crisis at local government level in South Africa and the threat that this poses to the political order in the country. Being a regional hegemon, any political disruptions in South Africa also threaten the geopolitical stability of the entire Southern African region. There remains a great deal of scope for future geopolitical co-operation around water within the Southern African Development Community that can secure a sustainable sources of future water supplies for South Africa and generate further income for the country’s neighbours. The article evaluates the current water situation in the country, explains the water related geopolitical considerations that the country has to take into account, investigates the ideological basis for government policy and institutional strategy and the impact that this has on the capacity of the state to deliver sustainable and reliable water access to local communities, and then evaluates some case studies that include both failures and a success story. This assessment includes various sources of literature that supply a theoretical conceptual basis for terms such as hydropolitics and ideology. These academic concepts provide the basis for the practical considerations that are an integral part of the ideologically ? based hydropolitical ontological assessment. The article concludes with some broad recommendations on how the country could mitigate some of the hydropolitical challenges that it faces.

Abstract:
Households in many cities worldwide consume substantial amounts of water, but increasing aridity will result in serious water supply challenges in the future. In South Africa, droughts are now a common phenomenon, with severe implications on water supply for urban households. Developing interventions to minimise the impacts of drought requires understanding of users’ perceptions of water scarcity, water use practices, and participation in water conservation practices. Using household surveys across different income groups (low, medium, and high) in Makhanda, South Africa, this study investigates households’ perceptions of water scarcity, water use, and conservation practices as a basis for designing pathways for sustainable water use practices. Results indicate that a substantial proportion of households were aware of water scarcity and attributed it to poor municipal planning rather than drought and wasteful use practices. Households reported good water use behaviour, but wasteful practices (e.g., regular flushing of toilets) were evident. Gender, age, education, and environmental awareness influenced water use practices, but the relationships were generally weak. Households participated in water conservation measures but felt the local municipal authority lagged in addressing water supply challenges. The implications of the study are discussed.

Abstract:
South Africa is facing severe water supply and water quality problems as a result of its limited water resources and other complicating factors. Adequately educated and trained water practitioners are needed to address these problems to ensure economic prosperity and a reasonable standard of living for all South Africans. Training and education needs are analysed in this paper and available programmes and initiatives to deliver the water practitioners needed are discussed. The main areas where training and education is needed include education at community level to educate local water committee members and community support personnel; training of technical staff to operate and maintain water treatment and supply schemes; and education of high-level scientists and engineers to develop new technologies, to improve performance, design and management of processes, plant and projects.

Abstract:
Balancing water demand and supply in South Africa involves high levels of uncertainty. The Department of Water and Sanitation (DWS) is responsible for making decisions to either increase water supply or decrease water demand so as to ensure that sufficient water is available, when and where it is needed. However, no retrospective analyses of such decisions have been found. One way to assess such decisions is to evaluate the associated costs and benefits thereof. Therefore the primary aim of this study is to evaluate the costs and benefits of selected water supply options, and of the decision-making associated with those options. In order to achieve this purpose, four case studies were analysed within a mixed-methods research paradigm, which used both quantitative and qualitative methods, including unit reference value (URV) analysis, inter- and intra-case analysis and content analysis to examine the success of the decisions made. The four case studies were conducted on the Inyaka, Nandoni, Berg and De Hoop dams and their catchments. Firstly, estimated and actual project costs were compared using unit reference analysis and inter-case analyses. Secondly, the reduction of mean annual runoff (MAR) caused by invasive alien plants (IAPs) and the cost of clearing them in the dam catchments were evaluated using inter-case analyses. Information thus gathered was used together with data from DWS documentation and the results of interviews with ten key specialists, to analyse the decision-making process that led to the decision to build De Hoop Dam (the most recent case study). The rational decision-making model (RDMM) was used as a framework within which to analyse and evaluate this decision-making process. This study has also demonstrated how the RDMM can be used to assess decision-making associated with water supply development. The results of this study show that there is considerable variation of estimated costs (at the time that the decision to build the dam was taken) in relation to the actual costs of building the dams and that Ministers were not put in a position to understand the full long-term costs or the opportunity costs of the proposed dams. Furthermore, the most recent IAP data (2008) shows that the impact on water security by IAPs could not offset the water security resulting from building each of the four dams. However, if IAP management is not continued in these catchments, the projected reduction of MAR by IAPs will compromise water security within 45 years. Given the almost exponential spread and densification of IAPs, together with their long-term impact on MAR and increased costs of controlling them, it is clear that IAP management should have been factored into water supply decision-making from the outset. In the analysis of the decision to build the De Hoop Dam, the results show that while the decision-making process that culminated in the decision to build the dam did not follow the steps of the RDMM, DWS appears to have followed a somewhat similar approach. It was found that while there was a need for the provision of additional water in the Olifants catchment, this need was overstated and the resulting overestimation caused the scale and size of the dam to be larger than it could and probably should have been. Additionally, it appears that DWS‘s decision to build the De Hoop Dam themselves, rather than having it built by the private sector, may have been less than optimal. It is recommended that, in future decision-making, DWS needs to incorporate multiple alternative options into the same solution, and to ensure that decision-makers are put into a position to make informed decisions, including adequate consideration of externalities. Furthermore, DWS needs to employ decision-making models such as the RDMM to facilitate retrospective analyses to improve their institutional knowledge. Keywords: water resources management, dams, invasive alien plants, decision-making, unit reference values, rational decision-making model.

Abstract:
In recent years South Africa has experienced numerous service delivery protests. These protests are a result of the lack of delivery of basic services such as water and sanitation (amongst others). To address this, local governments have taken part in benchmarking initiatives (National Benchmarking Initiative, Municipal Benchmarking Initiative) and regulation programmes (BlueDrop,GreenDrop) in an effort to improve the quality of potable water and sanitation services. The latter of these focuses on the quality of the water services delivered and neither focus on the efficiency with which this delivery is achieved. This study uses both nonparametric (data envelopment analysis) aswell as parametric (stochastic frontier) methods to assess the efficiency of water service provision in South Africa over a six year period from 2005 to 2010. Subsequently, the method which is most suited for use in the South African context is proposed. In addition, this study demonstrates how these methods can be used to determine the effectiveness of benchmarking initiatives, namely the National Benchmarking Initiative, in improving the efficiency of water service provision. Furthermore, additional insight into the selection ofm in them out of n bootstrap procedure for efficiency evaluations is established through a simulation study. The inclusion of efficiency evaluations into South African benchmarking initiatives provides new and important insight into the standard of water service delivery. As such, the techniques used in this study illustrate how efficiency analysis can enhance benchmarking initiatives in South Africa.

The aim of the research study was to examine and analyse the main constraints faced by the Polokwane Local Municipality in delivery water services to Mabokelele Village. For the researcher to be able to achieve the aim of the study, key research questions were posed which enabled the researcher to gather / collect data that helped shed more light in the research project. Research questions such as what are the constraints faced by the Polokwane Local Municipality in water delivery services, and what strategies are been to address those constraints and how effective are those strategies, were posed to the participants of this research study. The study used the qualitative research design. Respondents were seen as experts of their own life situation. Face to face interviews were used to collect data from the participants. Data analyses was done in the form of content data analysis. The key findings of the research project:- Shortage of skills in financial management, inadequate water service infrastructure, inadequate human resource for water service delivery, lack of co-operation between the Polokwane Municipality and the Mabokelele Induna and lack of community participation and consultation by the Polokwane Local Municipality and long delays caused by the tendering process were identified as the key findings for the study. Recommendations for the study was guided by the findings of the research project. The following served as recommendations for the study : Polokwane Local Municipality should ensure that people with financial management skills and project management are employed to avoid under-spending of the budget. Community participation and consultation should be key when implementing projects to the community, Department of Water Affairs to ensure that enough water service infrastructure is provided so that the Municipality can function properly. Dwarf should speed up the transfer of officials to Polokwane Local Municipality and lastly, the red tapes in the tendering processes should be minimized to avoid long delays in the approval of water projects.

Abstract:
The supply of water to 'disadvantaged' areas of KwaZulu-Natal has in the past received low priority. Local government is now faced with supplying water to large, sometimes dispersed, rural populations. Groundwater has been utilised informally as a water supply for some years, but the impetus provided by the Department of Water Affairs and Forestry's White Paper has compelled those responsible for water supply to seriously consider groundwater as a sustainable option. The development potential or success of groundwater in its role as a reliable water supply is dependent on acceptance of the resource by the communities, appropriate level of service, yield sustainability and safe quality. Apart from the social aspects, the yield and groundwater quality characteristics of the aquifers under consideration must be used to determine the best hydrogeological features to target during exploration. A total of 993 borehole records, from a recent government drought relief programme, were used to compare the yield, water quality and best geophysical exploration and drilling techniques of the main hydrolithologies in rural KwaZulu-Natal. The results of comparative analysis shows that the competent rocks of the Natal Group and Natal Metamorphic Province and the karstic Uloa Formation of the Maputaland Group have the best overall potential for water supply. The unconsolidated sediments of the Maputaland Group also have good potential, but have some salinity problems. The Karoo Supergroup sediments and volcanics have moderate potential, with the argillaceous rocks having the worst potential of the Karoo rocks. The contacts between the Ecca Group shales and sandstone have the best potential of the Karoo Supergroup sedimentary hydrolithologies. Fractures clearly enhance the groundwater potential of most hydrolithologies, with fractured Dwyka Group tillites rated as having one of the best development potentials of all the hydrogeological targets in KwaZulu-Natal, despite the hydrolithology's poor water-bearing characteristics. Dolerite contacts with sedimentary rocks are commonly targeted features in groundwater development. However, the results from this research showed that, apart from the Natal Group's contact with dolerite, these targets have poor development potential. In general, contacts between different hydro lithologies. Health related quality was found to be adversely affected in argillaceous hydrolithologies, such as the majority of Karoo rocks which had high levels of sodium and chloride and Natal Metamorphic Province schists which had elevated sodium, chloride and fluoride. Crystalline and arenaceous hydrolithologies generally exhibited good quality groundwater. A comparison between the different geophysical methods for each target feature indicates that there are appropriate methods to use to detect anomalies related to water-bearing features. The large number of dry boreholes drilled in locations with recorded geophysical anomalies can be either a function of the water-bearing characteristics of the formation, human error or background noise. The cost of using the different geophysical methods vary considerably. The order of increasing cost is magnetics, VLF, EM-34, electrical resistivity profiling followed by vertical electrical sounding. Drilling has a large influence on the development potential of certain aquifers due to the high costs involved. Most of the secondary aquifers will require percussion drilling which is the cheapest method of drilling commonly used. Some very unstable formations within fractured or highly weathered rock may need ODEX drilling to enable drilling to advance. ODEX drilling in these conditions is very costly and can double the cost of drilling compared to air percussion. The unconsolidated sediments of the Maputaland Group can only be drilled by mud rotary or ODEX techniques. The relative costs of these two methods arer very similar with ODEX being slightly cheaper. Because of the high expense of drilling in the sands it is recommended that alternative sources, possibly from shallow hand-dug wells, be considered as appropriate methods of accessing groundwater. The aspects of groundwater yield and quality of aquifers, appropriate geophysical siting and drilling methods, together with social considerations will all contribute to the success of groundwater development in rural KwaZulu-Natal.

ENGLISH ABSTRACT: A vast literature on the incompatibility of socio-economic development and environmental conservation (also referred to as sustainable development) has developed over the past few years. This study takes on the form of a critical, problemdriven discussion and evaluation of the applicability and viability of the concept of capacity-sharing to the current South African water management regime. Within the study, the complexities involved in the shift from a supply- to demandoriented management strategy are examined in depth. This transition in strategy proves to be problematic for water policy makers and managers because of past management regimes and structures, measurement related problems, incorrect or insufficient definition of criteria needed for demand-oriented approaches and the emotional complexities regarding water use. Developments in water policy are currently at a point where problems are experienced regarding the practical implementation of proposed water demand-oriented policy. The concept of capacity-sharing is explained and discussed in detail, leading to the identification of the applicability to three of the most important problems (basic contradiction within the 1998 National Water Act, initial allocation for market adoption and equity within the market) faced within the transition towards a demand-oriented approach. This study found that the concept of capacity-sharing does hold applicability in addressing the above-mentioned three problems towards the transition to a demand-side management approach. Capacity-sharing, therefore, should be part of this timely transition and the state should make use of the advantages of this concept. To support this view, seven studies are proposed for further research to address the problems as mentioned in section 5.2 of the thesis.
AFRIKAANSE OPSOMMING: 'n Uitgebreide literatuur aangaande die onversoenbaarheid van sosio-ekonomiese ontwikkeling en omgewingsbewaring (ook volhoubare ontwikkeling genoem) het oor die afgelope paar jaar ontwikkel. Hierdie studie neem die vorm van 'n kritiese, probleemgedrewe bespreking ten opsigte van die toepasbaarheid en relevansie van die konsep van kapasiteitsdeling binne die orde van huidige Suid Afrikaanse waterbestuur, aan. Die vele aspekte van die klemverskuiwing van 'n aanbod- na 'n vraag-georiënteerde waterbestuur-strategie, word ook beklemtoon. Hierdie oorgang is problematies vir waterbeleid-formuleerders en bestuurders as gevolg van vorige waterbestuur-ordes en strukture, meetbaarheid georiënteerde probleme, foutiewe of onvoldoende definieering van watergebruik-regte en die emosionele kompleksiteite van water. Tans, word probleme rakende die praktiese implementering van voorgestelde vraag-georienteerde waterbeleid ervaar. Die konsep van kapasiteitsdeling word in detail verduidelik en bespreek waarvandaan die toepasbaarheid op drie van die belangrikste probleme (basiese kontradiksie binne die 1998 Nasionale Waterwet, aanvanklike verdeling van water gebruik regte vir opname binne die mark en die kwessie van regverdigheid binne die mark) vir die oorgang na 'n vraaggeoriënteerde strategie geïdentifiseer word. Die studie het bevind dat die konsep van kapasiteitsdeling wel relevansie ten opsigte van die bogenoemde drie probleme tydens die oorgang na 'n vraag-georiënteerde strategie, inhou. Kapasiteitsdeling behoort dus deel te vorm van die oorgangsfase na 'n vraag-georiënteerde water bestuur strategie en die staat behoort gebruik te maak van die konsep se voordele. Ter ondersteuning hiervan word sewe studies voorgestel vir verdere navorsing ten opsigte van die probleme soos geïdentifiseer in afdeling 5.2 van die tesis.

Abstract:
This study explores views behind the failure of water supply projects to achieve sustainability, primarily from the 'users' perspective, and at a secondary level from the perspective of the government/funders. One completed water supply project was selected as a case study for the research project. The overriding principle behind the water infrastructure delivery programme is that the service must be provided in a sustainable manner, and that the community must actively participate and be involved in all the phases of the project. The provision of water is not simply as it might look. In reality it is a complex process, which involves a number of organisations with different, yet important roles and responsibilities. Ongoing collaboration is important among these organisations if the service is to be provided efficiently and in a sustainable manner. In particular, local government has a Constitutional obligation to provide services to all consumers in an efficient, affordable, economical and sustainable manner. The National and Provincial governments, however, have a number of responsibilities in the field of water services. Semi-structured interview method was used to collect data from respondents. Two sets of interview schedules were developed, one for the community/water project committee members, and the other for the government officials. The data collected was analysed both qualitatively and quantitatively. This analysis enabled the researcher to draw findings, make conclusions and propose recommendations. The findings and conclusions of the study point to lack of clarity on roles and responsibilities; gender and cultural constraints; and, poor training and capacity and building of the community as being some of the reasons for the failure of the project. The recommendations proposed entail, inter alia, massive community mobilisation and awareness creation programmes; improvement in levels of the service; adoption of a gender-sensitive approach to project development; and, implementation of a training and capacity building process in the community in order to 'revitalise' the project. The study has merely focussed on one water project and sets the scene for further exploration of the subject. It certainly highlights some critical issues around sustainability of water projects, and hopefully will contribute towards the ongoing debate in this area.

Previous government policy dictated that municipal services should not be distributed equally to all South Africans. Consequently, large inequalities in access to water supply and sanitation services were created along racial and geographic lines. After 1994, government policy sort to rectify this situation, largely through pro-poor service provision policies and programs. Continuous and accurate monitoring and reporting of access statistics is crucial to ensuring that progress is made. Progress within the provinces, however, would not have been equal due to the difficulty with providing services to different regions. As such, large disparities still exist. In order to assess the current inequality, local municipalities were grouped according to access to adequate services and their progress made from 2001, using the statistical method of cluster analysis. It was discovered that provinces, with access to improved services for over 75% of households, had municipalities with similar access to adequate services; this includes Western Cape, Gauteng and Free State. For the other provinces, great inequalities were found between municipalities. Some municipalities showed a decline in access to improved services; this is despite provincial access to improved services increasing for all provinces. Cases emerged where local municipalities in the same district municipality did not show similarly changes in access to improved services. The progress between water supply and sanitation provision was dissimilar, with growth occurring in different timeframes. A large number of municipalities showed negative progress for sanitation for 2007-2011 despite the fact that the Bucket Eradication Programme – aimed at diminishing the number of bucket facilities in the country - was established in 2005. The lag in sanitation progress between 2007 and 2011 could be attributed to the fact that sanitation provision from 2007 was focussed in rural areas, which are demonstrably difficult to deliver services to; that poorly built toilets needed restoration, diverting funds from providing new facilities; and that transferring responsibility of sanitation provision from DWA to DHS in 2009 led to non-efficient functioning of the National Sanitation Programme. More provinces showed a correlation between progress made between 2001 and 2011, and prior access to adequate services for water supply than sanitation. This coupled with the fact that rural municipalities had a greater capital expenditure than other local municipalities for water supply and not for sanitation, indicates that the pro-poor initiatives have been more successful in water supply than in sanitation. This highlights that sanitation provision has been challenging and slow.

Abstract:

The water resources management regime has shifted from one focusing almost exclusively on augmenting supply to one where ensuring access, equity and sustainability are an integral part of the process. A growing demand for water and the fact that the amount of fresh water is constant raises the impression of water scarcity will occur. Indications are that the notion of access to water for basic needs as well as access to productive water underpins perceptions of scarcity. This thesis interrogated perceptions of scarcity in a small rural community in order to understand the role water can play in developing sustainable livelihoods.

Abstract:
This research study addresses the problem of whether local government can afford free basic water in rural areas. To achieve this objective a comprehensive literature study was performed, which included: · Lessons in water sector approaches from international experience and how these experiences compare with the South African situation. 1.The current basic water supply legislation in South Africa and how this legislation affects the subsidy arrangements and the financing of free basic water. 2.The operation and maintenance cost and the benefits of effective operation and maintenance of water supply schemes. A model was developed that could estimate the cost of rural water supply per household per month from the operation and maintenance data that was collected over a period of twenty-two months from a water supply scheme. As part of the provision of free basic water, a nine-step flow chart was developed to determine rural water operation and maintenance subsidy and a free basic water policy to help local government make informed decisions. The model was tested on different water supply schemes to verify the accuracy of the models estimation of the cost of rural water supply per household per month. The information obtained from the literature and from the test of the model resulted in various recommendations and conclusions.

Abstract:
WFE nexus is an important aspect in building sustainable economies. Water is used in food production while water supply and food processing require energy. Understanding the interrelationships of the nexus components is a growing interest for researchers and policymakers towards sustainable development. This chapter analyses the in-depth meaning of the WFE nexus, its importance, and its involved processes. The chapter also evaluates the effects of climate change on the nexus using case examples in South Africa. It also proposes a road map to facilitate better management of the nexus by recommending useful action plans. These action plans prioritize on baseline data collection, optimization of WFE nexus processes and cooperative management of resources, and climate change adaptation.

Abstract:
Houston began the twentieth century as a small cotton port linked to the Gulf of Mexico by a ship channel. It became an important center of oil production and refining before World War II, a leading producer during the war and its aftermath, and the global capital of energy focusing on technological innovation, refining, and petrochemicals as the world economy globalized. As it grew, the city drew migrants, Anglo- and African-American, from the U.S. South, many from Louisiana, to become a diverse but not simply segregated city. The long-term economic benefits of oil-led development allowed unequal yet shared gains and funded the rise of leading medical centers, sustaining a diversified economy after the 1980s oil bust made it a symbol of a major city built on oil. It expanded employment and improved infrastructure, but economic opportunities and physical growth came with high environmental costs, including health challenges and urban problems ranging from water supply, to pollution, to chronic flooding—as the city grew with a new wave of migration from Mexico into the twenty-first century.

"levels which normally oscillated between 80,000 and 100,000 per year, and which in 1975 had soared up to 118,000 workers, were sharply reduced to 40,000 thereafter [First, 1982]. This mainly affected the southern part of Mozambique by creating massive rural unemployment. The towns had no capacity to absorb this surplus labour since employment was drastically re-duced in the towns as well. The latter process was due to the fall in employ-ment in domestic work (servants) and in the tourist sector (restaurants, hotels, bars, etc.). The exodus of Portuguese settlers and the virtual standstill of tourism (which catered for South Africans and Rhodesians) had amplified the problem of structural employment in the towns. The rural unemployed could not merely fall back on family agriculture since this was heavily dependent on cash income from wage work. Oxen and ploughs, farm implements, water reserves, etc. were normally paid for with wages from mine labour or other wage work. Furthermore, due to this cash inflow from wage income, a more interactive type of division of labour developed within the rural areas of southern Mozambique. Hence, peasants without oxen and plough would rent the services of peasants who did, and pay for it out of wage income. Brick-makers, carpenters, house-builders, tailors, mechanics were to be found among the middle peasantry who relied on these activities (usually acquired through mine labour) to supplement their income from farming. In a similar fashion, local transport and petty com-merce were sidelines of middle peasants stabilised by the influx of wage income. The reduction in mine labour employment deeply affected the viability of this internal division of labour within the rural economy. Finally, the impact of the reduction in mine labour was not evenly spread among the peasantry, since only those who held valid work certificates from the recruitment agency could continue to go to the mines. Other peasants were cut off altogether. This introduced a sharp element of differentiation within the rural econonmy. Those who could continued to go to the mines not only had cash income but also a guaranteed access to commodities (including means of production), while within Mozambique shortages were rapidly turning into a goods famine. However, rural unemployment was not merely a phenomena of the south. In central Mozambique, wage work to Rhodesia dropped sharply with the closure of the border between Mozambique and Rhodesia since 1976, and as a result of the war situation which developed thereafter. As stated in above, the concentration of resources on the state sector further weakened the basis of family agriculture at a time when a considerable part of its cash income through wage labour was cut off. While the colonial situ-ation was characterised by persistent labour shortages within the rural economy and continued state intervention to keep labour cheap (through the imposition of forced labour and forced cultivation of crops as well as by fragmentation of labour markets to avoid competition for labour to drive up the wage levels), the post-independence situation became characterised by rural unemployment and an intensified flow of people from the rural areas to the towns in search of wage work. The priority accorded to investments led to the slow expansion in the supply of consumer goods and in 1981 it actually fell by eight per cent: six per cent."

Abstract:
ABSTRACT Located in the eastern end of Niger delta; the Rio Del Rey (RDR) basin has a unique, complex multi-staged geological features and different types of Structures. This study has aimed to better understand the different structural and stratigraphic setting of the fields within the RDR basin and the way they control the hydrocarbon occurrences. To do that, an integrated 2D and 3D seismic interpretation was done targeting the toe thrust boundary, the upper Cretaceous unconformity and four key horizons of different depth levels in the Tertiary formations. Twelve regional profiles of contrastive orientations that cover the whole basin were interpreted to identify the regional structures; well correlation was done to identify the shallower tertiary settings while additional detailed grids of interpretation at the northeastern and southwestern corners and the seismic facies analysis of the whole RDR study area were used to classify the stratigraphic setting at the deeper regions. The results have revealed that the RDR basin is mainly controlled by thrusting, diapirism and detachment fault structures. The major toe thrust zone is found southern of Ngosso and trends in the northeast-southwestern direction. Gravitational tectonism becomes the primary deformation process shaping the structures as the sediments accumulation increases to the south and consequently, several shale ridges were formed. These ridges and their lateral movement from North to South along with the whole sediments increasing have caused a slope instability of the lower ductile Akata shale formation; what caused the forming of the detachment faults zone in the Northern and middle parts of the RDR basin. The Oongue Turbidites of Eocene were deposited in the northeastern part of the basin in deep water fans by the main sediments supply from the North and the East with various sand thicknesses due to the structural system. The hydrocarbon potential accumulations are found in the mid to upper Tertiary formations and the deeper Upper Cretaceous, but most of the oil and gas fields are located in shallower deltaic reservoirs associated with fault-bounded traps related to shale ridges and diapir structures. Considerable amounts of hydrocarbons were also found within the turbidites sands of Oongue (NE) and Isongo (SE).

Abstract:
US and international applications for large onsite cogeneration (steam and power) systems are emerging as a near term market for the PBMR. The South African PBMR demonstration project applies a high temperature (900°C) Brayton cycle for high efficiency power generation. In addition, a number of new applications are being investigated using an intermediate temperature range (700–750°C) with a simplified heat supply system design. This intermediate helium delivery temperature supports conventional steam Rankine cycle designs at higher efficiencies than obtained from water type reactor systems. These designs can be adapted for cogeneration of steam, similar to the design of gas turbine cogeneration plants that supply steam and power at many industrial sites. This temperature range allows use of conventional or readily qualifiable materials and equipment, avoiding some cost premiums associated with more difficult operating conditions. As gas prices and CO2 values increase, the potential value of a small nuclear reactor with advanced safety characteristics increases dramatically. Because of its smaller scale, the 400–500MWt PBMR offers the economic advantages of onsite thermal integration (steam, hot water and desalination coproduction) and of providing onsite power at cost versus at retail industrial rates avoiding transmission and distribution costs. Advanced safety characteristics of the PBMR support the location of plants adjacent to steam users, district energy systems, desalination plants, and other large commercial and industrial facilities. Additional benefits include price stability, long term security of energy supply and substantial CO2 reductions. Target markets include existing sites using gas fired boilers and cogeneration units, new projects such as refinery and petrochemical expansions, and coal-to-liquids projects where steam and power represent major burdens on fuel use and CO2 emissions. Lead times associated with the nuclear licensing process may support early applications in the 2018–2020 timeframe. This paper summarizes the design options likely to shape these emerging steam and cogeneration applications.
