Book excerpt: November 2000 The introduction of green revolution technologies in wheat and rice production in Pakistan's Punjab province reversed the country's food crisis and stimulated rapid agricultural and economic growth. But resource degradation through intensification, monocropping, and mismanagement of water resources has offset much of the productivity effect of technological change. The introduction of green revolution technologies in wheat and rice production in Asia in the mid-1960s reversed the food crisis and stimulated rapid agricultural and economic growth. But the sustain-ability of this intensification strategy is being questioned in light of the heavy use of external inputs and growing evidence of a slowdown in productivity growth and degradation of the resource base. Ali and Byerlee address the critical issue of long-term productivity and the sustainability of Pakistan's irrigated agriculture. To estimate changes in total factor productivity in four production systems of Punjab province, they assemble district-level data on 33 crops, 8 livestock products, and 17 input categories. They find that average annual growth in total factor productivity was moderately high (1.26 percent) for both crops and livestock for the period 1966-94, but observe wide variation in productivity growth by cropping system. A second, disaggregated data set on soil and water quality reveals significant resource degradation. The authors use the two data sets to decompose the effects of technical change and resource degradation through application of a cost function. They find that continuous and widespread resource degradation (as measured by soil and water quality variables) has had a significant negative effect on productivity, especially in the wheat-rice system, where resource degradation has more than offset the productivity effects of technological change. Degradation of the health of the agro-ecosystem was related in part to modern technologies, monocropping, and mismanagement of water resources. The results call for urgent analysis of technology and policy options to arrest the degradation of resources. This paper--a joint product of the Rural Development Department and the Asian Vegetable Research and Development Center--is part of a larger effort to support the development of sustainable intensification of irrigated agricultural systems. The study was funded by the Bank's Research Support Budget under the research project "Total Factor Productivity Growth in Post-Green Revolution Agriculture of Pakistan and Northwest India."

Available in PDF, EPUB and Kindle. Book excerpt: This article attempts to determine the long-term productivity and sustainability of irrigated agriculture in the Indian and Pakistan Punjabs by measuring trends in total factor productivity for production systems in both states since the advent of the Green Revolution. These measurements over time and across systems have resulted in three major findings. First, there were wide spatial and temporal variations between the two Punjabs. Although output growth and crop yields were much higher in the Indian Punjab, productivity growth was higher by only a small margin. Moreover, the lowest growth in productivity took place during the initial Green Revolution period (as opposed to the later intensification and post-Green Revolution periods) and in the wheat-rice system in both states. The time lag between adoption of Green Revolution technologies and realization of productivity gains is related to learning-induced efficiency gains, better utilization of capital investments over time, and problems with the standard methods of productivity measurement that downwardly bias estimates, particularly during the Green Revolution period. Second, input growth accounted for most of the output growth in both Punjabs during the period under study. Third, intensification, especially in the wheat-rice system, resulted in resource degradation in both Punjabs. Data from Pakistan show that resource degradation reduced overall productivity growth from technical change and from education and infrastructure investment by one-third. These findings imply the need for policies that promote agricultural productivity and sustainability through public investments in education, roads, and research and extension; and that reduce resource degradation by decreasing or eliminating subsidies that encourage intensification of inputs.

Available in PDF, EPUB and Kindle. Book excerpt: Back cover blurb Rising agricultural productivity has driven improvements in living standards for millennia. Today, redoubling that effort in developing countries is critical to reducing extreme poverty, ensuring food security for an increasing global population, and adapting to changes in climate. This volume presents fresh analysis on global trends and sources of productivity growth in agriculture and offers new perspectives on the drivers of that growth. It argues that gains from the reallocation of land and labor are not as promising as believed, so policy needs to focus more on the generation and dissemination of new technologies, which requires stepping up national research efforts. Yet, in many of the poorest nations, a serious research spending gap has emerged precisely at the time when the challenges faced by agriculture are intensifying. The book focuses on how this problem can be redressed in the public sector, as well as on reforms aimed at mobilizing new private sector actors and value chains, particularly creating a better enabling environment, reforming trade regulations, introducing new products, and strengthening intellectual property rights. On the demand side, the book examines what recent research reveals about policies to reduce the barriers impeding smallholder farmers from adopting new technologies. Harvesting Prosperity is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers. “As rightly argued by the authors, growth in agricultural productivity is the essential instrument to promote development in low-income agriculture-based countries. Achieving this requires research and development, upgrading of universities, reinforcement of farmer capacities, removal of constraints to adoption, and the development of inclusive value chains with interlinked contracts. As important, such efforts also need to be placed within a context of comprehensive agricultural, rural, and structural transformations. However, in many countries implementation of the requisite policies has been lagging. This book, with contributions from many top experts in the field, provides the most up-to-date presentation of this argument and explains in detail how to successfully put its ideas into practice. Governments, the private sector, and civil society organizations need to study it carefully to turn the promise of agriculture for development into a reality.“ Alain de Janvry and Elisabeth Sadoulet Professors of the Graduate School, University of California at Berkeley

This book was released on 2021-06-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, some countries in Asia have been more successful than others in addressing poverty and malnutrition. The key question is what policies, strategies, legislation and institutional arrangements have led to a transformed agricultural sector, effectively contributing to poverty alleviation and addressing malnutrition. The great majority of national policymakers within and outside the Asia-Pacific region are keen to understand the causes of agricultural development and transformation in successful countries in Asia. A large number of studies have been conducted and some of them link specific public policies and interventions to successful agricultural transformation. However, there seems to be lack of focus on the policy, legislative and institutional environments that have enabled or impeded agricultural transformation in Asia. National policymakers are likely to benefit significantly from adequate and convincing information on successful and relevant experiences in successful transformation. Countries are interested in what their neighbours and peers have done, and why some have achieved impressive results. The main purpose of this study is to take stock of public sector experiences in facilitating and enabling agricultural transformation in selected countries in Asia. The study focuses on key public sector interventions, in particular policies, legislation and institutional innovations, because these areas have so far not been adequately researched.

Book excerpt: Globally, significant work has been done to enhance our current understanding of the nutritional and anti-nutritional properties, processing, storage, bioactivity, and product development of wheat, opening new frontiers for further improvement. Wheat Science: Nutritional and Anti-Nutritional Properties, Processing, Storage, Bioactivity, and Product Development addresses the topics associated with the advances in understanding the wheat biochemical, nutritional, and rheological quality. Improving crop varieties by either conventional breeding or transgenic methods to obtain nutritionally enhanced crops has the advantage of making a one-time investment in research and development to have sustainable products. Features: Includes topics associated with the nutritional composition and anti-nutritional properties Addresses the effects of different processing technologies on flour yield and end products Reviews the effects of storage on nutritional, baking and rheological quality, organoleptic quality, etc. Processing and storage technologies have impacted the nutritional quality and the bioavailability of nutrients in wheat. Due to its peculiar grain protein composition, especially gluten protein, wheat has extensive usage in making numerous end products, eaten round the clock. Researchers have demonstrated a significant effect of alteration of flour-processing technologies on the rheological quality of end products. This book provides a holistic understanding and covers recent developments of wheat science under one umbrella. Emphasis is placed on current trends and advances in nutritional and anti-nutritional properties, processing, storage, bioactivity, and product development. Additionally, efforts have been made to compile the available information on the application of different ingredients of wheat in the industry and pharma sectors.

Available in PDF, EPUB and Kindle. Book excerpt: The majority of the poor and hungry people in the world live on small farms and struggle to subsist on too little land with low input - low yield technologies. At the same time, many other smallholders are successfully intensifying and succeeding as farm businesses, often in combination with diversification into off-farm sources of income. This book examines the growing divergence between subsistence and business oriented small farms, and discusses how this divergence has been impacted by population growth, trends in farm size distribution, urbanization, off-farm income diversification, and the globalization of agricultural value chains. It finds that policy makers need to differentiate more sharply between different types of small farms than they did in the past, both in terms of their potential contributions towards achieving national economic growth, poverty alleviation, and food security goals, and the types of assistance they need. The book distinguishes between smallholders that are business oriented, subsistence oriented, and at various stages of transition to the non-farm economy, and discusses strategies appropriate for assisting each type. The book draws on a wealth of recent experience at IFAD and elsewhere to help identify best practice approaches.
Download or read book Feeding India written by Bill Pritchard and published by Routledge. This book was released on 2013-08-15 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security is one of the twenty-first century’s key global challenges, and lessons learned from India have particular significance worldwide. Not only does India account for approximately one quarter of the world’s under-nourished persons, it also provides a worrying case of how rapid economic growth may not provide an assumed panacea to food security. This book takes on this challenge. It explains how India’s chronic food security problem is a function of a distinctive interaction of economic, political and environmental processes. It contends that under-nutrition and hunger are lagging components of human development in India precisely because the interfaces between these aspects of the food security problem have not been adequately understood in policy-making communities. Only through an integrative approach spanning the social and environmental sciences, are the fuller dimensions of this problem revealed. A well-rounded appreciation of the problem is required, informed by the FAO’s conception of food security as encompassing availability (production), access (distribution) and utilisation (nutritional content), as well as by Amartya Sen’s notions of entitlements and capabilities.
