The impact of domestic water user cultures on water efficiency interventions in the South East of England : lessons for water demand managementKnamiller, C. January 2011 (has links)
The need for a more sustainable approach to water consumption has increasingly gained attention in the last decade. The domestic sector accounts for over half of abstracted water in the UK and, as such, has become a major target for water efficiency interventions. Current research and water efficiency interventions are dominated by a positivist approach, focusing on a limited range of factors that can be quantitatively measured. This thesis questions the dominant approach and argues that a more holistic overview of water efficiency can be achieved through the consideration of socio-technical and behavioural theories. Taking a more constructivist approach, this research draws on four theories from socio-technical and behavioural fields and combines them to create a framework for the analysis of water efficiency interventions. The framework is applied to two case studies, exploring water users' perceptions of water, water supply, personal water use, and their responses to the water efficiency interventions. The case studies were selected to provide examples of current mainstream approaches to water demand management. Research methods used included semi-structured interviews and observation. The research findings support the argument that the current dominant approach to domestic water efficiency interventions is limited and, in some cases, ineffectual. Issues of trust, knowledge, motivation and the relationships between water users and water companies were raised. The thesis concludes that the use of a constructivist perspective could help to provide a more effective approach to understanding and improving water demand management.

Allocation and use of water for domestic and productive purposes: an exploratory study from the Letaba river catchmentMasangu, T.G. January 2009 (has links)
Magister Economicae - MEcon / In this thesis, I explore the allocation and use of water for productive and domestic
purposes in the village of Siyandhani in the Klein Letaba sub-area, and how the
allocation and use is being affected by new water resource management and water
services provision legislation and policies in the context of water reform. This
problem is worth studying because access to water for domestic and productive
purposes is a critical dimension of poverty alleviation.The study focuses in particular on the extent to which policy objectives of greater equity in resource allocation and poverty alleviation are being achieved at local level with the following specific objectives: to establish water resources availability in Letaba/Shingwedzi sub-region, specifically surface and groundwater and examine
water uses by different sectors (e.g. agriculture, industry, domestic, forestry etc.,); to explore the dynamics of existing formal and informal institutions for water resources management and water services provision and the relationship between and among them; to investigate the practice of allocation and use of domestic water; to investigate the practice of allocation and use of irrigation water.The study concludes that there is a problem of water scarcity in the study area and that the water scarcity is caused by the growth in the population, specifically in the Giyani area; these problems are exacerbated by financial and institutional obstacles within local institutions of governance. The water scarcity is not, therefore, natural but anthropogenic in nature.The water scarcity is not felt by all sectors, however: some farmers have access to water for irrigation, while many others face great challenges in their farming activities.Overall, people in Siyandhani and surrounding villages surrounding villages in the Letaba Catchment do not have access to water because of human action, hence the use of the concept of manufactured scarcity. The lack of access to water, it is argued,leads to the violation of the human right to water. This study concludes that water reform, which is widely seen as a priority for South Africa, has not yet reached the villages of the Klein Letaba.

Ecnomic value of water for Agriculture, Hydropower and Domestic Use : A case study of the Lunsemfwa catchment, ZambiaPhiri, Daniel January 2020 (has links)
The Lunsemfwa river catchment is of paramount importance to the Zambian economy, particularly with regards to energy, agricultural and water for domestic, as well as wildlife. Water shortages during dry spells in the area present a huge problem for the various stakeholders in the basin. As the impact of climate variability increases in the basin, water resources managers in the basin are increasing challenged to efficiently allocate decreasing reserves of water resources against increasing levels of demand. This paper attempts to highlight the value of water resources to the earlier mentioned sectors; hydropower, agriculture and households, in order to inform allocation decisions in the Lunsemfwa catchment area of Zambia. The paper uses the SDDP method to investigate the average cost of electricity production, coupled with market electricity prices to ascertain the value of a unit of electricity given reservoir outflow levels. The PF method was used to evaluate the marginal value of water is agriculture, while the value of water for domestic consumers was evaluated using the Contingent Valuation method, particularly the willingness to pay, which essentially uses market prices to represent the consumers’ willingness to pay. A value of US$93/MWh is attached to hydropower produced here, while the marginal value of water in agriculture is estimated to be US$0.068/m3. The willingness to pay for connection to piped water is approximately US$34.13, while the monthly value is US$6.9. The Gross Financial Value (GFV) generated from hydropower, agriculture and domestic water supply is US$24,174,000, US$ 262,083,045.91 and $7,140,000.00 respectively.
