This book was released on 2019-11-13 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

Available in PDF, EPUB and Kindle. Book excerpt: The National Research Council's Science and Technology for Sustainability Program hosted two workshops in 2011 addressing the sustainability challenges associated with food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, explored the availability and quality of commonly used indicators for food security and malnutrition; poverty; and natural resources and agricultural productivity. It was organized around the three broad dimensions of sustainable food security: (1) availability, (2) access, and (3) utilization. The workshop reviewed the existing data to encourage action and identify knowledge gaps. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, focused specifically on assuring the availability of adequate food supplies. How can food production be increased to meet the needs of a population expected to reach over 9 billion by 2050? Workshop objectives included identifying the major challenges and opportunities associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Workshop participants discussed long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also examined the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity posed by climate change. This is a report of two workshops.

Book excerpt: First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Available in PDF, EPUB and Kindle. Book excerpt: gricultural science policy in the United States has profoundly affected the growth and development of agriculture worldwide, not just in the A United States. Over the past 150 years, and especially over the second th half of the 20 Century, public investments in agricultural R&D in the United States grew faster than the value of agricultural production. Public spending on agricultural science grew similarly in other more-developed countries, and c- lectively these efforts, along with private spending, spurred agricultural prod- tivity growth in rich and poor nations alike. The value of this investment is seldom fully appreciated. The resulting p- ductivity improvements have released labor and other resources for alternative uses—in 1900, 29. 2 million Americans (39 percent of the population) were - rectly engaged in farming compared with just 2. 9 million (1. 1 percent) today— while making food and fiber more abundant and cheaper. The benefits are not confined to Americans. U. S. agricultural science has contributed with others to growth in agricultural productivity in many other countries as well as the Un- ed States. The world’s population more than doubled from around 3 billion in 1961 to 6. 54 billion in 2006 (U. S. Census Bureau 2009). Over the same period, production of important grain crops (including maize, wheat and rice) almost trebled, such that global per capita grain production was 18 percent higher in 2006.

This book was released on 1977-02-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resource Allocation and Productivity in National and International Agricultural Research was first published in 1977.Agricultural research in developing countries has grown rapidly in recent years. As the research system has expanded, questions about the productivity of research and the allocation of research resources have become important issues for development planners, science managers, donor agencies, and other individuals and institutions concerned with research operations and opportunities.In this volume, forty contributors - natural and social scientists and research administrators - provide a comprehensive analysis of the implications of agricultural science and technology for agricultural development. They examine recent evidence on the returns to investment in national and international agricultural research systems and explore the relevance of social and economic factors for the organization and management of these systems. In a final section they discuss research strategy and management issues that will affect the future productivity and organization of both the international and the national research systems.The material is based on papers given at a conference held at Airlie House, Virginia, sponsored by the Agricultural Development Council. Funding was provided through the U.S. Agency for International Development (USAID), support of the Council's Research Training and Network Program, and by additional assistance from the World Bank.

Available in PDF, EPUB and Kindle. Book excerpt: Agricultural Productivity: Measurement and Sources of Growth addresses measurement issues and techniques in agricultural productivity analysis, applying those techniques to recently published data sets for American agriculture. The data sets are used to estimate and explain state level productivity and efficiency differences, and to test different approaches to productivity measurement. The rise in agricultural productivity is the single most important source of economic growth in the U.S. farm sector, and the rate of productivity growth is estimated to be higher in agriculture than in the non-farm sector. It is important to understand productivity sources and to measure its growth properly, including the effects of environmental externalities. Both the methods and the data can be accessed by economists at the state level to conduct analyses for their own states. In a sense, although not explicitly, the book provides a guide to using the productivity data available on the website of the U.S. Department of Agriculture/Economic Research Service. It should be of interest to a broad spectrum of professionals in academia, the government, and the private sector.

Download or read book Productivity Growth and Resources Degradation in Pakistan's Punjab written by Derek Byerlee and published by World Bank Publications. This book was released on 1999 with total page 38 pages. Available in PDF, EPUB and Kindle. 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."
