Rainfed Agriculture Has A Distinct Place In Indian Agriculture, Occupying 68 Per Cent Of The Total Cultivated Area And Supporting 40 Per Cent Of Human And 60 Per Cent Of Livestock Population. Agriculture In Rainfed Areas Continues To Be A Gamble Because Farmers In The Rainfed Region Face Many Uncertainties. In The Light Of Growing Population And Demand To Increase The Food Production Especially In The Developing Countries With Arid And Csemi-Arid Climate, This Book Mainly Focuses On The Land Use Diversification Involving Multi-Disciplinary Approaches For Sustainability In The Rainfed Regions.The Present Book Consists Of Twenty-Three Articles In All By Experts From Various Central & State Government Organisations, Agricultural Universities And Research Organisations Concerned With Rainfed Agriculture. These Articles, Covering Various Aspects Of Land Use Diversification For Sustainable Rainfed Agriculture, Have Been Arranged Into Five Sections: (A) Diversification: Need Of The Hour, (B) Natural Resources Dynamics, (C) Alternate Land Uses, (D) Case Studies, And (E) Capacity Building. Each Of The Articles Is Highly Informative And It Is Hoped That This Book Will Give An Interesting Insight Into The Varied Rainfed Agriculture Related Problems In India. It Highlights The Possible Measures Sustainable Management Of Land And Water Resources, Land Use Diversification, Alternate Land Uses Based On Climate, Soil And Crop Suitability, Etc. That Would Help Increase The Cropland As Well As Crop And Fodder Production In Rainfed Areas. The Present Book Enriched With Selected Case Studies Will Be Particularly Useful For Students, Teachers, Researchers And Scientists Working In The Area Of Rainfed Agriculture And Agricultural Planning For Sustainable Development.

This book discusses ways of increasing production/unit area by making full use of the soil and water under the harsh climatic conditions of semiarid areas. This leads to improved sustainability, increased availability of fresh produce, which is vital for human health and higher incomes for small and marginal farmers. Arid and semiarid areas account for almost 70 per cent of the total cropped area of India. In these areas physical constraints like low and erratic rainfall, high temperature, high wind velocity, low fertility, poor soil structure, salinity of soil and ground water all limit reliable crop production. In the absence of any type of aggregation, the soils are highly erodible, lack structure and have a very coarse in texture with low water holding capacity. Intensive agricultural practices, increasing population pressure, climatic changes, environmental pollution, loss of biodiversity, soil erosion, salinization and water depletion are all threatening the sustainability of agriculture. In view of the mounting demand for food, it is vital to link enhanced food production with nutritional security, conservation of natural resources, increasing farmers’ incomes, employment generation through agricultural diversification. Horticulture, particularly of fruit trees, can play a major role in solving the problem of nutrition, as fruits are rich source of vitamins and minerals and have antioxidant properties. Fruit trees, which are mostly deciduous, add leaf litter to the soil, and this ultimately helps to improve the condition of the soil. In addition, fruit trees are known to reduce soil erosion and reduce run off. The trees also play a major role in purifying the environment as they are the known carbon sequesters. Fruit-tree cultivation is a profitable preposition. There is no scope to increase the land surface; all increase in productivity therefore has to be from the available land. This means introducing cropping systems that can meet the basic food, fodder and fuel requirement of farming families.

This book is a ready reference on recent innovations in dryland agriculture and reinforces the understanding for its utilization to develop environmentally sustainable and profitable food production systems. It covers the basic concepts and history, components and elements, breeding and modelling efforts, and potential benefits, experiences, challenges and innovations relevant to agriculture in dryland areas around world.

Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.

There are chapters on varied topics covering the major gamut of dryland agriculture. The topics covered by eminent-scientists are : Dryland agricultural research in India - a historical perspective. The eminence of authors and the institutions they represent gives credence to the contents of the book. Research and development workers, all would like to possess this book for ready reference and use.
