Book excerpt: This working paper presents the results of the Pakistan Component of the Rice-Wheat Consortium Project on ‘Sustaining the rice-wheat production systems of Asia’. Rice and wheat crops are main nsources of human food and substantially contribute to feeding livestock. The advent of the green revolution in the 1960s resulted in a tremendous increase in the production of these two cereal crops and the rice-wheat cropping system emerged as a very important source of food supply in South Asia. Recent symptoms of stagnant growth rates in productivity and the degradation of the resource base pose serious challenges to future food security and natural resources management in the region. The growing scarcity of water in the region

Available in PDF, EPUB and Kindle. Book excerpt: 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 productivity This 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 excerpt: Progressively erratic monsoon patterns threaten the ability of the rice-wheat system in South Asia’s Eastern Gangetic Plains to provide food and livelihoods for their food insecure and impoverished people. Ongoing research has identified early crop planting and improved irrigation use as key entry-points to overcome these challenges. However, there are critical knowledge gaps on the complex feedback mechanisms of these activities resulting in their low and incomplete adoption. These feedback mechanisms comprise of intertwined factors beyond classic water challenges in the rice-wheat system, including temperature rise, pest and disease pressure, value chains, and policy discrepancies between household and national scales. This thesis investigates and evaluates farmers’ planting and irrigation activities in the rice-wheat system through a socio-ecological systems framework to fill the knowledge gaps – thus identifying constraints and opportunities to overcome water-related challenges for food security and poverty reduction. Empirical data on farmers’ perspectives of planting and irrigation activities were collected and analysed – indicating that farmers and policymakers alike aim to synchronize crop planting with the monsoon onset, but that irrigation use at planting and during in-season dry spells is frequently delayed by uncertainty in weather signals, groundwater availability and availability of other inputs. Simulated crop yield patterns were then used to indicate the potential of synchronizing rice planting with the monsoon onset and fully utilizing irrigation to buffer against drought to contribute to food security. The results suggest that this strategy may indeed increase productivity and resilience in the Eastern Gangetic Plains – but not in the Western Gangetic Plains. However, an analysis of large-scale household survey data on crop production indicate that the poverty reduction potential of productivity increases is limited to the largest farmers, while most farmers need to rely on additional income streams for significantly boosting their incomes. This is followed by a concluding reflection on rice-wheat system contribution to sustainable development, building a framework for managing water and managing time in agroecological systems, and the merits, challenges, and current potential of interdisciplinary mixed methods approaches to tackle complex issues in sustainable agriculture. Lastly, this thesis discusses the implication for irrigation development and management, resilience to climate change and adaptation pathways, the role of the monsoons for sustainable agriculture, and future potential for better targeting of interventions and policies.

Book excerpt: 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.
