Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka
Provedor de dados: 31
Autores: 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 current and future water resources development in the Lake Tana Basin, Ethiopia
Provedor de dados: 31
Autores: McCartney,   Matthew P.; Alemayehu,   Tadesse; Shiferaw,   Abeyu; Awulachew,   Seleshi Bekele.
Lake Tana, located in the headwaters of the Blue Nile, is valuable for many people including the communities who live around the lakeshore and those who live immediately downstream. The area has been identified as a region for hydropower and irrigation development, vital for economic growth in Ethiopia. A multidisciplinary study was conducted to assess the possible impacts of this development. This study found that current development has benefited some local people but adversely affected others. Future development will exacerbate pressure on the lake. Hard choices must be made about how the water is best utilized. It is important that all stakeholders, including local people, are involved in the decision-making process.

Integrated Management of the Blue Nile Basin in  Ethiopia: Hydropower and Irrigation Modeling
Provedor de dados: 31
Autores: Block,   Paul J.
Ethiopia is at a critical crossroads with a large and increasing population, a depressed national economy, insufficient agricultural production, and a low number of developed energy sources. The upper Blue Nile basin harbors considerable untapped potential for irrigation and hydropower development and expansion. Numerous hydrologic models have been developed to assess hydropower and agricultural irrigation potential within the basin, yet often fail to adequately address critical aspects, including the transient stages of large-scale reservoirs, relevant flow retention policies and associated downstream ramifications, and the implications of stochastic modeling of variable climate and climate change. A hydrologic model with dynamic climate capabilities is...

Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa
Provedor de dados: 31
Autores: 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...

Health impacts of small reservoirs in Burkina Faso.
Provedor de dados: 31
Autores: Boelee,   Eline; Cecchi,   Philippe; Kone,   Andre.
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...

Modeling Water Resources Management at the Basin Level: Methodology and Application to the Maipo River Basin
Provedor de dados: 31
Autores: Cai,   Ximing; Ringler,   Claudia; Rosegrant,   Mark W.
Limited water resources are increasingly constrained by growing water demand for agricultural, industrial, and domestic uses, which in turn exacerbates environmental degradation and water-quality problems. This research report develops and applies a comprehensive decision-support tool for examining these issues at the river-basin level—the natural unit of analysis for water allocation and use. Authors Ximing Cai, Claudia Ringler, and Mark Rosegrant develop an integrated hydrologic– economic river-basin model, simulating water flows, salinity balances, and crop growth under water-allocation scenarios. One of the main advantages of the model is its ability to reflect the dynamic interactions of essential hydrologic, agronomic, and economic components and to...

Minimizing the negative environmental and health impacts of agricultural water resources development in Sub-Saharan Africa
Provedor de dados: 31
Autores: McCartney,   Matthew P.; Boelee,   Eline; Cofie,   Olufunke O.; Mutero,   Clifford M.
This paper provides a synopsis of environmental and health impacts arising from agricultural water development in sub-Saharan Africa and recommends ways to increase the sustainability of investments in irrigation by giving greater prominence to health and environmental concerns. In many places in the region, irrigation is a key means of enhancing agricultural productivity that can reduce poverty and improve livelihoods. However, failure to adequately foresee, plan and manage the negative environmental and health impacts arising from irrigation undermines the sustainability of many schemes and can worsen poverty. To improve sustainability, environmental and health issues must be at the core of future irrigation development with much greater emphasis on the...
