Book Description
Tests the hypothesis that timely surface cultivation before monsoon or winter rains in semiarid and arid areas will assist reclamation of abandoned saline soils. The effect of surface cultivation, monsoon rains, depth to water table, and ground water salinity on secondary salinity are evaluated using a numerical model, SWAP93.

Book Description
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.

Book Description
This report is based on the results of an action research program in pakistan conducted by the International Water Managament Institute (IWMI). An analysis of empirical data is presented in the light of existing theoretical kmowledge on collective action for natural resources management. the report also highlights the current constraints associated with a wider application of some of these findings, which reflect the difficulties in pursuing large-scale institutional reforms in the rural sector of developing coutries. finally, the report raises some key research issues that need to be explored further.

Book Description
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.
