Estimating Productivity of Water at Different Spatial Scales Using Simulation Modeling Summary:

A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Land and Water Productivity of Wheat in the Western Indo Gangetic Plains of India and Pakistan Summary:

The purpose of this study is to analyze variations in wheat yields and to assess the range of factors affecting wheat yields and profitability of wheat production in the selected irrigation systems in India and Pakistan. The study attempts to identify constraints and opportunities for closing the existing yield gaps. It is hypothesized that substantial gains in aggregate yields can be obtained by improved water management practices at the farm and irrigation-system levels.

Poverty Dimensions of Irrigation Management Transfer in Large scale Canal Irrigation in Andra Pradesh and Gujarat India Summary:

A growing body of evidence on the impacts of irrigation management transfer (IMT) shows that IMT risks aggravating rural poverty. For governments that aim to continue irrigation management while ensuring that it contributes to poverty alleviation, a "pro-poor" mode of IMT needs to be designed and implemented. That is, a mode of IMT that benefits poor farmers while benefiting non-poor farmers equally, or perhaps to a lesser degree. The present research explores the scope for pro-poor modes of IMT in canal irrigation, focusing on large-scale canal irrigation schemes in India.

Water Scarcity and Managing Seasonal Water Crisis Summary:

Coping with scarcity of water supply for managing irrigation under uncertain and inadequate conditions has become part and parcel of many irrigation systems in the semiarid tropics of Asia. Based on a case study of the Kirindi Oya Irrigation and Settlement Project (KOISP) in southern Sri Lanka, this report provides evidence of the uncertain and inadequate inflow into the reservoir and its impact on the seasonal planning.

Wells and Welfare in the Ganga Basin Summary:

This report analyzes the history of groundwater development in the eastern Uttar Pradesh region over the 1950-1990 period. Its main conclusion is that the story of groundwater-based livelihood creation in the Ganga basin is one of failed public initiatives and successful adaptive responses by private agents. However, tube-well-induced agrarian dynamism in eastern Uttar Pradesh and north Bihar in recent years can spread to the entire basin if public policy makers learn correct lessons from the experience of these two subregions.

Small Irrigation Tanks as a Source of Malaria Mosquito Vectors Summary:

Thousands of small irrigation reservoirs (tanks) exist in rice ecosystems in malarious regions of south Asia. The potential of these tanks to generate malaria-transmitting mosquitoes has not been adequately evaluated. Through a study of nine small irrigation tanks in north-central Sri Lanka, this report provides an assessment of the capacity of tanks to generate malaria and nuisance mosquitoes, factors that contribute to mosquito generation, and measures that could ameliorate the problem.
