Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI's long-term research goal: to determine the extent and depth o...
Describes the use of satellite remote sensing and GIs techniques to analyze the agricultural performance and sustainability of the Bhakra Irrigation System in India. Demonstrates the cost-effectiveness of these techniques as diagnostic tools for irrigation system improvement and the advantages of...
Describes the results of an irrigation performance evaluation using remote sensing techniques, GIS procedures, and hydrologic modeling at a regional scale. Demonstrates how advanced information technologies support the analysis of irrigation performance by facilitating an in-depth study of a larg...
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...
The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 20...
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...
Outlines IWMI's external and other comparative performance indicators that allow for analysis of irrigation performance across systems. The purpose of these indicators is to understand the current situation with respect to productive utilization of land and water, to compare relative performance ...
Changes in the way water is used in one part of a river basin often affect how water is used somewhere else in that basin. This report introduces the concept of hydronomic ( hydro water + nomus management) zones that were developed to help untangle some of the complexities of basin-wide water res...
