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.

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.

This book deals with the development of irrigation in the subcontinent since the beginning of settled agriculture, and its possible connections with the occurrence of salinity and alkalinity in irrigated lands.

Zero tillage (ZT) for wheat is one of the most widely adopted resource-conserving technologies in the rice-wheat systems in northern India. In areas of Haryana with rice-wheat systems, 36.5 percent of all farmers practice ZT on 35 percent of their wheat area. Yet the literature measuring the impact of ZT on farmers’ fields is scarce. This study fills this gap by using the data collected from a random sample of 717 farmers from 50 villages in 10 districts of Haryana. It applies the difference-in-differences method to five-year recall data on wheat yields in ZT and conventionally tilled plots of land to quantify the crop loss due to unseasonal rains right before wheat harvests in March 2015. The results reveal significantly lower wheat yield losses in the ZT plots than in the conventionally tilled plots. On average, farmers suffered yield losses ranging between 3.73 and 4.53 quintals per hectare in 2015 due to unseasonal rains. The loss was lower by 1.05–1.10 quintals per hectare in ZT plots. The analysis clearly shows that adoption of ZT helped in reducing crop loss in wheat by 24–28 percent, valued at 1,523–1,595 Indian rupees (Rs.) per hectare (approximately US$22.50 per hectare). The loss avoided due to ZT is nearly equal to the prevailing rental rate of the ZT machine (Rs. 1,500 per hectare) in Haryana. Climate models suggest that the incidence of short-duration acute hydro meteorological events is likely to increase in years to come. Such events are hard to predict and prepare for, and dealing with them hinges mainly on disaster relief. However, our results show that adoption of ZT is one possible way to reduce potential loss from some of these weather events and that ZT is therefore well characterized as a climate-smart technology.
