Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka AgEcon
Molle, Francois; Renwick, Mary E..
The Uda Walawe Irrigation and Resettlement Project (UWIRP) located in the Southern dry zone of Sri Lanka was initiated in the early 1950s. The original plan for the UWIRP was a highly ambitious social, economic and physical engineering project aimed at creating a modern, profitable agriculture sector. This report examines the history of water resources development and investment decisions for the UWIRP over a period of 50 years and uncovers underlying processes that shaped the evolution of the project and highlights the limitation of viewing development as a mere set of technical and social engineering endeavors.

Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa AgEcon
McCartney, Matthew P.; Arranz, Roberto.
Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...

Groundwater pollution and emerging environmental challenges of industrial effluent irrigation in Mettupalayam Taluk, Tamil Nadu AgEcon
Mukherjee, Sacchidananda; Nelliyat, Prakash.
Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage based irrigation practices, at least for a developing country like India. The disposal of effluents on land has become a regular practice for some industries. Industries located in Mettupalayam Taluk, Tamil Nadu, dispose their effluents on land, and the farmers of the adjacent farmlands have complained that their shallow open wells get polluted and also the salt content of the soil has started building up slowly. This study attempts to capture the environmental and...

Multiple-use water services to advance the millennium development goals AgEcon
van Koppen, Barbara; Moriarty, Patrick; Boelee, Eline.
This research report presents the findings of the first phase of the action-research project "Models for implementing multiple-use water supply systems for enhanced land and water productivity, rural livelihoods and gender equity." Multipleuse water services, or "mus" in short, is a participatory, integrated and poverty-reduction focused approach in poor rural and peri-urban areas, which takes people's multiple water needs as a starting point for providing integrated services, moving beyond the conventional sectoral barriers of the domestic and productive sectors.

Productivity of water in agriculture: Farmers’ perceptions and practices AgEcon
Mahoo, Henry F.; Mkoga, Zakaria Juma; Kasele, Sydney Stephen; Igbadur, Henry E.; Hatibu, Nuhu; Rao, Karuturi P.C.; Lankford, Bruce A..
Stakeholders in agriculture and water related issues have different perceptions about the productivity of water. This is evident by the different definitions of productivity of water, though most of the definitions hinge around the benefits accrued from water use. The viewpoint of smallholder farmers’ regarding the productivity of water is important in order to promote the concept of productivity of water in a country like Tanzania. This is because 95 percent of the farmers are smallholders. This paper presents the farmers’ understanding of the productivity of water in the Mkoji sub-catchment (MSC) in the Ruaha River Basin in Tanzania. It also presents their practices aimed at increasing the productivity of water in the area. It reveals that the concept of...

Reducing poverty through integrated management of groundwater and surface water AgEcon
International Water Management Institute (IWMI); Global Water Partnership (GWP Advisory Center).
The full poverty-fighting potential of existing irrigation schemes is not being realized—largely because of inequitable water distribution and unsustainable land and water management practices. An integrated water resources management (IWRM) approach reveals opportunities to reduce poverty and improve overall agricultural productivity and sustainability in these systems. Research in India and Pakistan has highlighted one such opportunity—integrated management of surface water and groundwater—that has great potential for water-short systems with variable groundwater resources. By considering groundwater availability and quality when allocating surface water, water managers could improve the situation of millions of poor farmers with inadequate access to...

Spatial variation in water supply and demand across river basins of India AgEcon
Amarasinghe, Upali A.; Sharma, Bharat R.; Aloysius, Noel; Scott, Christopher A.; Smakhtin, Vladimir U.; de Fraiture, Charlotte.
India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.

Taking a multiple-use approach to meeting the water needs of poor communities brings multiple benefits AgEcon
International Water Management Institute (IWMI); International Water and Sanitation Centre; Global Water Partnership (GWP).
This briefing was produced by International Water Management Institute (IWMI), the IRC International Water and Sanitation Centre, the Technical Committee of the Global Water Partnership (GWP) and the GWP Advisory Center at IWMI. It draws primarily on research from the Multiple Use Systems (MUS) project and the Productive Uses of Water Thematic Group (Prodwat) (see references for further reading). The brief complements Catalyzing Change, the GWP handbook for developing IWRM and water efficiency strategies and plans, and the associated policy and technical briefs. Single-use approaches to water development and management do not reflect the realities of poor people’s water use. People use domestic water supplies for activities such as irrigating backyard...
