About this eBook

PREFACE Global population was only one billion in 1800 AD, doubled by 1930 and reached three billion mark by 1960. However, it took only 39 years to double itself again by 1999, when it reached to six billion mark. It is estimated that by 2100 it will again double itself to twelve billion mark. Most of the future increase in population will be in developing countries of Asia, Africa and Latin America, where more and more area under agricultural production systems have been developed at the cost of natural eco-systems, which gradually deplete the soils of organic matter, nutrients and water, making them unsuitable in the long-run leading to the question on their sustainability. Sustainability is generally seen as human oriented, long term and involving interaction with natural systems. A sustainable agricultural production system must, therefore, produce economically the needed food, fibre, feed and fuel without depleting the natural resources and without deterrent to environment. It must discourage regional imbalance and encourage gender equality. Through a large amount of information has been generated on various aspects of sustainable agriculture, they are scattered in literatures. Thus, a compilation of available information has been strongly felt keeping in view the requirement of students, teachers, research scientists, administrators and those interested in the subject. The book contains chapters on sustainable agriculture, farming systems, agro-forestry, organic farming and crop and environment. The chapters have been arranged systematically, simple to understand and comprehend in an integrated manner. There may still be some lacuna in the book, which will be corrected in the subsequent editions if these are brought to my knowledge. Any suggestion from readers shall be welcomed for further improvement of the book in future. In writing the book, works of authors quoted and materials incorporated freely from various sources are gratefully acknowledged. Finally, I wish to place on record my appreciation for the perseverance, support and encouragement provided by my wife Kiran, sons Rajnish and
Manish and daughters-in-law Monica and Shweta, which made this book a reality. 2010
