This report deals with some experiences of a set of irrigation systems situated in the Republic of Niger, along both banks of the Niger River. All these systems draw water from the river through low-lift, electrically powered pumping stations, which have been installed by the Government of Niger over the past 30 years. Irrigation of this kind is not a tradition in Niger. The introduction of this technology caused considerable changes in the way of life of local communities.

A study of the enormous differences in agricultural productivity that exist across farms and regions in Pakistan, where, for example, recent farm-level data from Sindh, indicates that irrigated wheat output per hectare varies from 0.5 to 5.4 tons across farms. Looks at the central goal of agricultural policy in the country, viz. improving and sustaining productivity, narrowing the existing productivity gaps, and enhancing resource use efficiencies to meet food requirements of a rapidly growing population.

More irrigated land is devoted to rice than to any other crop. A method to save water in irrigated rice cultivation is the intermittent drying of the rice fields, known as alternate wet/dry irrigation (AWDI). This report reviews previous studies in AWDI, with a focus on mosquito vector control, water saving, and rice yields. Examples are provided from a number of countries.

This document presents an analysis of experience in irrigation water charging, drawn from published literature and a series of six case studies. These sources provide a broad spectrum of experience from less-developed to more-developed countries. The aim has been to make an assessment of the claims concerning irrigation water charging as a tool for cost recovery (achieving financial sustainability) and demand management (achieving resource sustainability).

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.

Over the past two decades, significant investment has been made into agriculture-related natural resource management research in developing countries. This collection of case studies establishes a methodological foundation for impact assessments of NRMR through a discussion of research conducted by the CGIAR around the world.

Studies the low-cost alternative strategy of selective lining of watercourses to reduce seepage and increase irrigated areas in the Indian subcontinent. Satellite remote-sensing (SRS) is seen as a cost-effective evaluation tool in view of its large area of synoptic and repetitive coverage.

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 nothern 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.

Describes the use of a distributed hydrologic model to evaluate different data scenarios. 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; d) the timing and accounts used for water are changed?
