Última Basin-level use and productivity of water: examples from South Asia AgEcon Molden, David J.; Sakthivadivel, Ramasamy; Habib, Zaigham. Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

Ano: 2003 URL: http://purl.umn.edu/118402 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...

Ano: 2003 URL: http://purl.umn.edu/92663 Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia AgEcon Kim, Ungtae; Kaluarachchi, Jagath J.; Smakhtin, Vladimir U.. The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Ano: 2008 URL: http://purl.umn.edu/53025 An assessment of crop water productivity in the Indus and Ganges River Basins: current status and scope for improvement AgEcon Cai, Xueliang; Sharma, Bharat R.; Matin, Mir Abdul; Sharma, Devesh; Gunasinghe, Sarath. The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.

Ano: 2005 URL: http://purl.umn.edu/92245 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...

Ano: 2001 URL: http://purl.umn.edu/92769 The challenges of integrated river basin management in India: issues in transferring successful river basin management models to the developing world AgEcon International Water Management Institute, IWMI-TATA Water Policy Program. The problems that river basin institutions in the developed world successfully address—such as pollution, sediment buildup in rivers and the degradation of wetlands—are not the top priorities for Indian policy makers and people. The items that do top Indian agendas—providing access to water for drinking and growing food, eradicating poverty, and stopping groundwater overexploitation—are either unresolved in the developed world or have become irrelevant due to economic development. This does not mean that India and other developing countries cannot learn valuable lessons from models for Integrated River Basin Management. Loosely structured River Basin Organizations, such as Southeast Asia’s Mekong Commission, can contribute to basin welfare by serving as a...

Ano: 2008 URL: http://purl.umn.edu/118411 The global groundwater situation: overview of opportunities and challenges AgEcon Shah, Tushaar; Molden, David J.; Sakthivadivel, Ramasamy; Seckler, David. Groundwater offers us few but precious opportunities for alleviating the misery of the poor; but it poses many—and daunting—challenges of preserving the resource itself. A big part of the answer is massive initiatives to augment groundwater recharge in regions suffering depletion; but, in the ultimate analysis, these cannot work without appropriate demand-side interventions. The water vision of a world that future generations will inherit will have to be the one in which groundwater plays its full developmental, productive and environmental role but in a sustainable manner; and the framework of action to realize this vision will mean eschewing the current free-for-all in groundwater appropriation and use, and promoting a more responsible management of this...

In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of...

Ano: 2009 URL: http://purl.umn.edu/91869 Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability AgEcon Barry, Boubacar; Kortatsi, Benony; Forkuor, Gerald; Gumma, Murali Krishna; Namara, Regassa E.; Rebelo, Lisa-Maria; van den Berg, Joost; Laube, Wolfram. The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.
