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
Addressing a topic of major importance to the maintenance of world food supplies, this reference identifies knowledge gaps, defines priorities, and formulates recommendations for the improvement of the rice-wheat farming system. The book reveals new systems of rice intensification and management and illustrates the application of no-till and conservation farming to the rice-wheat system. With contributions from 65 international experts, and case studies from India, Nepal, Pakistan, and Bangladesh, Sustainable Agriculture and the International Rice-Wheat System focuses on seeding equipment and residue management, weed control, water and nutrient efficiency, and integrated pest management.

Book Description
This book is addressed to scientists, researchers, development specialists and policy makers who deal with natural resources and agriculture in the developing countries. It aims to (1) provide evidence of the impact of natural resource management research (NRMR) in the CGIAR; (2) establish a methodological foundation for impact assessments of NRMR; and (3) draw up a set of lessons for future impact assessment studies. The book consists of three main parts. Part I (chapters 1-3) provides the definitional, historical, and theoretical background for NRMR impact assessment in the CGIAR. Part II (chapters 4-11) presents the methods and results of seven case studies on the impact of NRMR projects carried out in the CGIAR. Two summary chapters (12 and13) are presented in part III. The book has a subject index.

Book Description
The dramatic increases in food prices experienced over the last four years, and their effects of hunger and food insecurity, as well as human-induced climate change and its implications for agriculture, food production and food security, are key topics within the field of agronomy and agricultural research. Contested Agronomy addresses these issues by exploring key developments since the mid-1970s, focusing in particular on the emergence of the neoliberal project and the rise of the participation and environmental agendas, taking into consideration how these have had profound impacts on the practice of agronomic research in the developing world especially over the last four decades. This book explores, through a series of case studies, the basis for a much needed ‘political agronomy’ analysis that highlights the impacts of problem framing and narratives, historical disjunctures, epistemic communities and the increasing pressure to demonstrate ‘success’ on both agricultural research and the farmers, processors and consumers it is meant to serve. Whilst being a fascinating and thought-provoking read for professionals in the Agriculture and Environmental sciences, it will also appeal to students and researchers in agricultural policy, development studies, geography, public administration, rural sociology, and science and technology studies.

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.
