This report analyzes a case from southern Sri Lanka, where the Samanalawewa dam and the Kaltota Irrigation Scheme (KIS) compete for the water of the Walawe river. At the catchment level, it is shown that dam releases are well attuned to the needs of KIS and to the occurrences of natural runoff, and that little of the dam water is "lost" to the river.

his research report discusses ecological aspects of schistosomiasis transmission and options for its control in irrigated areas in Africa through environmental measures. Human schistosomiasis is endemic in 46 African countries.After being infected by larvae emerging from human excreta and urine deposited in the water, freshwater snails act as intermediate hosts.

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.

his report addresses a specific context of massive inequity and unevenness in water allocation and distribution experienced presently by the water users in transitional Central Asian economies, as a result of broad-scale fragmentation of the previously large farms. The report describes action research aimed at making water distribution at the tertiary level more reliable, transparent and equitable.

This report highlights the potentially significant impacts on the hydrologic cycle and the importance of considering secondary effects, particularly with regard to water, resulting from the widespread adoption of global climate change mitigation measures. It is recommended that the implicit hydrologic dimensions of climate change mitigation should be more formally articulated within the international environmental conventions, and recognized within future UNFCCC negotiations on the CDM-AR provisions.

The purpose of this study was to identify risk areas in Thailand where insecticide resistance in malaria mosquitoes might develop as a consequence of crop protection activities in agriculture. The study provides guidelines on how to delineate risk areas. A review of insecticide resistance in disease vectors and the potential role of agricultural insecticides is presented.

The purpose of this paper is to summarize IIMI/IWMI’s past research and interventions related to irrigation management transfer and to document, to the extent possible, the academic, policy, and technical outcomes of these efforts. The application of a range of direct and indirect measurement techniques suggests an overall positive contribution from IWMI to IMT theory and application.

This report presents the findings of a study to assess changes to flows into, and downstream of, the Usangu Wetlands, located in the headwaters of the Great Ruaha River, Tanzania. Hydrological data, in conjunction with remote sensing techniques, were used to provide insights into changes that have occurred to the Eastern Wetland. Results indicate that, between 1958 and 2004, inflows to the wetland declined by about 70 percent in the dry season months (July to November) as a consequence of increased human withdrawals, primarily for irrigation.
