Book Description
The lives of more than a billion people depend on the answer!Thirty years ago, the Green Revolution changed the way agriculture was practiced on the Indo-Gangetic Plain (IGP). This valuable book critically analyzes and discusses the rice-wheat cropping system introduced at that time. The Rice-Wheat Cropping System of South Asia: Trends, Constraints, Productivity and Policy addresses the crucial question, ”Are the sustainability and productivity of this system in a state of decline?” The Rice-Wheat Cropping System of South Asia brings together information gathered from research institutions, government organizations, and farmer surveys. The analysis concentrates on the trends of rice-wheat cropping over time, paying special attention to the evidence of-and reasons for-changes in productivity. It also analyzes the impact of this regional system on soil fertility and water supplies, as well as the increasing demands for new and better fertilizers and pesticides. The Rice-Wheat Cropping System of South Asia looks at the problems that have arisen for both the rice and wheat phases, including: the need for changes in crop establishment techniques for crop diversification declining soil fertility changes in pest populations a host of water-management issues the need for policy redirection to sustain productivity growth the impact of global climate change sustainable improvements in productivityThis informative book is an essential planning tool for agronomists, policymakers, and agroeconomists. It is also a useful reference for anyone interested in the problems of famine and intensive cropping not only in South Asia but in the world.

Book Description
Both wheat and barley are two of the most important food and industrial crops in the world. Wheat and barley cultivation has experienced changes in practices due to factors such as methods of conservation agriculture, cropping systems, wheat varieties, changes in weather patterns, and international trade, necessitating new and different approaches for the successful management of emerging diseases and new pathotypes of pathogens. This valuable volume explores a multitude of new approaches and techniques for the effective management of emerging wheat diseases. This new volume presents the latest literature on management technology of diseases that affect the production of wheat and are capable of reducing grain yields as well as grain quality. These diseases include rusts, smuts, other foliar diseases such as blight, spots, blotch, powdery mildew, bunts, etc., as well as diseases such as Karnal bunt of wheat, which is of importance to international trade. This book will be highly valuable to researchers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat and barley. It also advances our knowledge in the field of plant pathology, plant breeding, and plant biotechnology, agronomy, and grain quality and pesticide industries. The book will serve as a reference on disease management technologies for the containment of losses in wheat and barley yields and will assist in maintaining wheat quality, reducing the cost of cultivation, increasing yield, and thus in helping to ensuring food security on a global level.

Book Description
The world has made enormous progress in the past 50 years toward eliminating hunger and malnutrition. While, in 1960, roughly 30 percent of the world's population suffered from hunger and malnutrition, today less than 20 percent doessome five billion people now have enough food to live healthy, productive lives. Agricultural development has contributed significantly to these gains by increasing food supplies, reducing food prices, and creating new income and employment opportunities for some of the world's poorest people.This book examines where, why, and how past interventions in agricultural development have succeeded. It carefully reviews the policies, programs, and investments in agricultural development that have reduced hunger and poverty across Africa, Asia, and Latin America over the past half century. The 19 successes included here are described in in-depth case studies that synthesize the evidence on the intervention's impact on agricultural productivity and food security, evaluate the rigor with which the evidence was collected, and assess the tradeoffs inherent in each success. Together, these chapters provide evidence of "what works" in agricultural development.

Book Description
This book features review articles that analyze current agricultural issues and knowledge. It also proposes novel, environmentally friendly solutions that are based on integrated information from such fields as agroecology, soil science, molecular biology, chemistry, toxicology, economics and the social sciences. Coverage examines ways to produce food and energy in a sustainable way for humans and their children. Inside, readers will find articles that explore climate change, food security, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. Instead of solving problems using the classical painkiller approach, which seeks only to limit negative impacts, sustainable agriculture treats challenges at their source. Because most societal issues are in fact intertwined, global and fast-developing, sustainable agriculture will bring solutions that have the potential to build a more peaceful world. This book will help scientists, decision-makers, professors, farmers and politicians build safer agriculture, energy and food systems for future generations.

Book Description
Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.
