It is supported by suitable examples and diagrams. The broad chapters included in the book are: Rainfed agriculture: Introduction, types, characteristics, distribution and importance; History of rainfed agriculture & watershed in India; Problems and prospects of rainfed agriculture in India; Soil and climatic conditions prevalent in rainfed areas; Drought: types, effect of water deficit on physio- morphological characteristics of the plants, Mechanism of crop adaptation under moisture deficit condition; Water harvesting: importance, its techniques, Efficient utilization of water through soil and crop management practices, Study of mulches and antitranspirants; Management of crops in rainfed areas; Contingent crop planning for aberrant weather conditions; Concept, objective, principles and components of watershed management, factors affecting watershed management; Integrated watershed development. The need for comprehensive information on rainfed farming relevant to undergraduate and postgraduate students of agriculture has been felt for quite some time. The advanced, diverse and need-based topics have been together for a systematic and comprehensive reading by the students and faculty in agriculture. The materials on subject matter is set forth in such a manner and order as to enable them to better understand and follow to a reasonable degree of uniformity and their approach to the problems of rainfed agriculture.

Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.

This book provides a comprehensive presentation of the realization of improved rainfed agriculture yield in semi-arid and dry land areas. The incentive of watershed programs is to increase the return on investment with over 20% for 65% of the projects that are currently underperforming. Besides techniques to improve the livelihood of the many small-scale farmers in developing countries, it includes examples and case studies for further support. The methods discussed have recently shown to be successful and economically remunerative in India and in various African countries. Intended for professionals (investors, policy makers), researchers and (post) graduate students working on dry land and sustainable agriculture and water and natural resources management. Suited for courses in dry land agriculture, soil and water management and watershed development.

A watershed is simply the geographic area through which water ows across the land and drains into a common body of water, whether a stream, river, lake, or ocean. The watershed boundary will more or less follow the highest ridgeline around the stream channels and meet at the bottom or lowest point of the land where water ows out of the watershed, the mouth of the waterway. Watersheds are important because the surface water features and stormwater runo- within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Management of the environment has been primarily focused on specic issues such as air, land, and water.

Crop water use can be increased by management of surface runoff, groundwater, irrigation, and soil water. Technological innovations to enhance availability of water for agricultural crops depend on soil and site-specific conditions. Devoted to the principles and practices of enhancing water use efficiency, Soil Water and Agronomic Productivity addresses current problems associated with water supplies required for agricultural purposes and food production. Written for professionals and students in agricultural fields, the book focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. It also presents techniques to conserve water in the root zone as well as remote sensing techniques to assess soil water regime and predict drought on a regional scale. Soil water management is crucial to reducing the vulnerability to agronomic drought. There are numerous examples of aquifers that have been severely depleted by misuse and mismanagement. Soil Water and Agronomic Productivity explains the factors and causes of the mismanagement of soil water and proposes options for sustainable and efficient use of scarce water resources. Meeting the global food demand will require careful worldwide management of soil and water resources, and this can only be done by sharing information and knowledge.

The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.
