Basin-level Use and Productivity of Water
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.

This book provides an in-depth analysis of existing methods of water management and highlights the gaps in the use of water in various river basins. Underlying the futility of 'quick fix' solutions, it puts forward various alternative strategies for water management. Using illustrative case studies, the author lists major challenges in water management: productivity improvement in key-use sectors, inter-sectoral allocation, trans-boundary resource management, and availability in deficient regions. Highlighting the opportunities for improving water productivity in agriculture, he also provides methodologies for generating country- and regional-level water balance scenarios. The volume also discusses the problems involved in allocating water in river basins. Kumar gives a detailed account of some of the widely known economic tools. He examines the institutional and policy measures for ensuring sustainable use of water and economic growth, including the creation of new organizations.
Modeling Water Resources Management at the Basin Level
The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.
