    A guide to technology selection and planning for village water supplies utilising groundwater and spring water sources
    (1989) Wiseman, Keith
    Providing a clean, potable supply of water is a critical problem in remote or underdeveloped rural areas. Water is needed for drinking, cooking, washing and bathing, but is often only available from traditional sources such as springs, rivers or ponds. These water sources are in most cases contaminated by livestock and cattle, and situated far from homesteads. During dry periods they often dwindle or dry up completely.

    Capacity building in analytical tools for estimating and comparing costs and benefits of adaptation projects
    (2005) Nkomo, Jabavu C; Sparks, Debbie; Callaway, John M; Hellmuth, Molly; Louw, Daniel; Gomez, Bernard E; Jallow, Bubu P; Njie, Momodou; Droogers, Peter
    The broad objective of AIACC project 47 was to develop the capacity to estimate and compare the benefits and costs of projects in natural resource sectors that reduce the expected damages from climate change in Southern and West Africa. There are two parts to this project. The first consists of using well-established principles from economic benefit-cost analysis to develop a framework to estimate the economic benefits and costs associated with the expected climate change damages avoided by a development project that does not take climate change into account. Then, these benefits and costs can be compared to the case where planners incorporate expected climate change into the project assessment. The second part consists of demonstrating this methodology in two project case studies, one in The Gambia and the other in South Africa. The South African case study examines the benefits and costs of avoiding climate change damages through structural and institutional options for increasing water supply in the Berg River Basin in the Western Cape Province. The Gambian study, on the other hand, focuses on the agricultural sector, particularly on millet, the predominant crop in the country. To facilitate analysis, the Gambian study uses a detailed water–crop model, defines and explores adaptation strategies with the model and uses the results to carry out an economic analysis. The South African project develops and applies a Berg River Dynamic Spatial Equilibrium Model as a water planning and policy evaluation tool to compare benefits and costs and economic impacts of alternatives for coping with longterm water shortages due to climatic change. Results from the study will contribute to the development of international climate change policies and programs, particularly in regard to adaptation activities in developing countries under the United Nations Framework Convention on Climate Change (UNFCCC).

    Knowledge and attitudes in the rural Western Cape towards pesticides in water sources
    (2004) Dalvie, Mohamed A; London, Leslie; Mbuli, Simphiwe; Cairncross, Eugene
    There is a need for pesticide water monitoring in South Africa and for community awareness with regard to chemical contamination of rural water sources. The results of two descriptive studies in the rural Western Cape are reported. One assessed water usage and the knowledge, attitudes and practices in relation to water of farm residents (229 participants from 60 farms) in the Slanghoek Valley, Hex River Valley and Grabouw (KAP) and the other (monitoring capacity survey), investigated water usage and the capacities of rural communities (63 farm residents from 16 farms in three local authorities and 8 environmental health officers (EHOs) from 7 local authorities) to conduct monitoring of pesticides in rural water sources. Most farm residents in both surveys identified protected sources such as groundwater from springs and boreholes (30 to 60%), and water from mountain dams (40 to 65%), as the most important sources for drinking and other domestic purposes. Many (> 40%), however, also reported farm dams. For use in the field (both drinking and other), potentially contaminated sources (river, subsurface drains, dams) were more frequently reported. Forty-eight percent of participants also reported swimming in farm dams. Other water sources reported included municipal, rain and canal water. In the monitoring capacity survey, 27 % reported using untapped water. About a third of respondents in the KAP survey reported living within 10 m of the nearest site of spraying and many used pesticides at home for pest control (41%) and in the garden (33%). While almost all participants (> 90%) in both surveys were aware that pesticides and polluted water could be harmful, many did not identify health effects (20%) especially chronic effects (91%) or reported no training (37%) in health effects. In all 7 districts surveyed in the monitoring capacity survey, water sources on farms are tested by EHOs. Only 3 (37%) respondents felt that there were enough persons conducting water monitoring in their area. Only 1 respondent reported that pesticides were monitored, and only in request to a complaint. Three state laboratories, that did not have the analytical capacity to conduct routine pesticide water monitoring at low (< 0.1 mg/l) detection limits, were identified as conducting water analyses. The study found that farm residents in the Western Cape are potentially exposed to pesticides through various environmental routes including water. This emphasises the need to monitor water for pesticides in the Western Cape, but in order to do this, human and laboratory resources and capacities to conduct routine pesticide water monitoring need to be increased.

    Water and sociality in Khayelitsha: an ethnographic study
    (2022) Kongo, Minga Mbweck; Nyamnjoh, Francis; Chitonge, Horman
    This study examines forms of social relationships created around unequal municipal water distribution in South Africa. Using the case of Khayelitsha, the study investigates residents' use of water to sustain their livelihood and build personhood. Water mobilises the formation of relationships in myriad ways. How residents, collectively and individually, imagine, negotiate and construct their future pathways around resources available to them in a social group is explored. Ethnographic tools are used to address how social formations are created around municipal water in Khayelitsha. The study looks into how inequalities related to access to water in Cape Town are produced with inequitable development patterns. Using incompleteness and conviviality as framework, the study seeks to understand how ideas of social formation, belonging, marginality, and physical and social mobility are produced, reproduced and contested around water. By focusing on the strategies deployed by residents, this study also seeks to describe the challenges of inadequate water access experienced by residents in less- provisioned areas. The multiple relations with, and complexities of, municipal water are chronicled, as well as how Khayelitsha residents think about, relate and respond to water. The empirical data reveal several structural issues characterising the formation of social relations: incompleteness, impoverishment, marginalisation, water access and minimal opportunities. Despite many challenges, frustration, and heavy reliance on communal taps, tanks, water trucks, and hydrants, shack dwellers particularly cherish an ideal of self-sufficiency with the limited amount of water they access. In this quest, they maintain social relations and resistance to the political economy of water. They achieve this by mobility from one settlement to another, maintaining a strong sense of community, belonging, social relationships, and household interdependence, connected to a sense of incompleteness and, to a more considerable extent, Ubuntu. This social practice is manifested in various forms: neighbourliness, water usage at communal points, land occupations, and strikes, amongst others. By combining the structural issues and aspects of social practices provided above, water is seen as a substance that constructs social formations through the phenomena of incompleteness and conviviality. The data were collected during several field visits between February 2020 and March 2021 through observation of interactions and participation in residents' social activities and formal and informal interviews and group discussions with a representative sample of residents in Khayelitsha.
