Empowerment of Farmer Organizations : The Case of the Farmer Managed Irrigated Agriculture Project, Sind Province Pakistan
(2001) Murray-Rust, Hammond; Memon, Yameen; Talpur, Mustafa
"This paper reviews the conditions and progress towards empowerment of farmer organizations under the Farmer-Managed Irrigated Agriculture Project in the Sindh Province of Pakistan. It discusses the conditions necessary to achieve the goal of an empowered and vitalized farmer organization, the issue of legal status, skill-building activities to build the capacity of the members to manage their own affairs, and institutional issues."
Impact Assessment of Rehabilitation Intervention in the Gal Oya Left Bank
(1998) Amarasinghe, Upali A.; Sakthivadivel, R.; Murray-Rust, Hammond
"Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors."
Modeling Scenarios for Water Allocation in the Gediz Basin, Turkey
(2001) Kite, Geoff; Droogers, Peter; Murray-Rust, Hammond; de Voogt, Koos
"Hydrological models are able to simulate the natural processes involved in translating precipitation to runoff with a reasonable degree of success. When such models are extended to include the nonnatural processes such as dams, reservoirs, diversions and irrigation, then they may be used to simulate the water resources of a basin. Such a model may also be used to evaluate past water resources and to assess the effects of past management decisions. Lessons learnt from the past can be used to predict the impact of future changes in water management. Next, if we believe the model adequately describes the basin processes, we can use it with completely different sets of data to evaluate the effects of alternative conditions such as changed land use, changed climate or changed management decisions on the water resources. Finally, such a model can be used in conjunction with economic models to optimize water use within a basin under different external conditions. "This report describes the use of a distributed hydrologic model to evaluate different data scenarios for the Gediz basin in Turkey. The study attempted to answer questions such as; what will happen to the basin water resources if a) there is a change in climate, b) it is decided that more water must be retained in the river for environmental reasons c) more water is extracted for urban and industrial use, or d) the timing and amounts of water used for irrigation are changed? The effects of such changes were evaluated in terms of their impacts on the yields of irrigated agriculture and on the volume of water discharged at the outlet of the basin."
Modeling Water Allocation between Wetlands and Irrigated Agriculture: Case Study of the Gediz Basin, Turkey
(2000) de Voogt, Koos; Kite, Geoff; Droogers, Peter; Murray-Rust, Hammond
"This report investigates how much water is required to maintain the freshwater reed beds that are the main shelter and breeding place for threatened bird species. The ability of Gediz basin to fulfill this requirement and the effects of this requirement on irrigated agriculture, the major competitor for water in the Gediz basin were subsequently examined."
Remodeling of Outlets in Three Pilot Distributaries Under the Farmer Managed Irrigation Project in Sindh Province, Pakistan
(2000) Lashari, Bakhshal; Murray-Rust, Hammond
"Addresses remodeling of outlets to achieve equitable water distribution where studies have shown considerable inequity. Recommendations are made for the implementation of remodeling that involve the farmer organizations. This process is to be undertaken jointly with the area water board staff."
Water Distribution Equity in Sindh Province, Pakistan
(2001) Murray-Rust, Hammond; Lashari, Bakhshal; Memon, Yameen
"The concept of equity of water distribution is widely used in assessment of irrigation water management performance; but in reality there is considerable confusion between the concepts of equity and equality. This research forms part of a larger study of Farmer Managed Irrigation in Sind Province."
Water Productivity in the Syr-Darya River Basin
(2003) Murray-Rust, Hammond; Abdullaev, Iskandar; ul Hassan, Mehmood; Horinkova, Vilma
"This report analyses water productivity and water-saving initiatives in the Syr-Darya river basin (SRB) of Central Asia. The report presents institutional and political aspects of water management in the basin - particularly a brief description of pre- and post-soviet developments in water management. Water allocation elements principles for different hierarchical levels in the basin are also discussed. The assessment of the performance of irrigation in SRB is presented as an analysis of the water-saving competition, funded by the World Bank (from 1999 to 2000). The competition itself is no longer operational, but the International Water Management Institute (IWMI) and the Scientific Information Center of the Interstate Commission on Water Coordination (SIC) based in Tashkent are funding the collection of data on water use. Water delivery, crop yields (cotton, wheat and rice) and water productivity were used as major indicators of performance for the irrigation system of the basin. The analysis was done for different levels of water use and management - farm, irrigation-system and basin levels were studied. The study was conducted for the head, middle and tail reaches of the basin. This analysis can be used by water managers, policymakers and potential donors as a tool for identifying the hierarchical levels and areas of the basin, where water management needs to be improved and water conservation is a possible solution for the existing water-related environmental problems."
