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.

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.

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 resource use.

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.

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.

Do women have effective land rights in practice? Research and policy have only recently begun to engage with the need for women to have independent rights to fields of their own. What needs to be done? Four areas for action are identified with associated strategies: improve women's claims on private land (e. g. through gender equal inheritance laws); improve women's access to public land (e.g. through land reform schemes); improve women's access to land via the market (e.g. through subsidised credit); and improve the viability of women's farming efforts (e.g.
