This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

The paper analyzes several aspects of the operation and effects of the T & V extension system. Specific questions related to the supply of, and demand for, extension agents (VEW) visits, the presence or absence of farm size bias in VEW visits, seasonal and longer-term variations in the pattern of VEW visits, the relative importance of the VEW as a source of information to farmers, and the crop yields obtained by farmers in relation to their main sources of agricultural advice are addressed in detail. The paper draws the following main conclusions. Most (85 percent) contact farmers are visited regularly, and the majority of noncontact farmers also have some interaction with VEWs, suggesting that the supply of extension services is adequate. VEWs appear to be more active in the dry season than in the rainy season, which may be attributable to an emphasis on irrigated crop technology. As experience with the T & V system increases, contact farmers appear to receive fewer visits from VEWs, but visits to noncontact farmers increase. VEWs play a more important role as a disseminators of information in areas operating the T & V system than in areas relying on the older community development system of extension.
