Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture embodies many concepts in its attempt to integrate all the aspects of farming systems into a holistic system. This book explores the processes that occur within the components of a sustainable system and shows where we can build upon our existing knowledge to develop the concepts of sustainable agriculture into the new conventional agriculture. Well-known researchers examine a variety of aspects, including production goals, environmental considerations, and economics, to build a knowledge base that allows readers to see where changes in agriculture must be made and how challenges can be met. They compare existing systems against definitions of sustainability and pinpoint those areas where improvements can be made in current systems to further the concepts of sustainability.

Available in PDF, EPUB and Kindle. Book excerpt: Livestock Play An Important Role In Human Society. Demand For Meat And Milk Is Soaring, And The World S Livestock Sector Is Growing At An Unprecedented Rate. The Greatest Constraint To Livestock Productivity Is The Shortage Of Feeds And Forages. Some Countries Import Cereal Grains In An Effort To Increase Livestock Production Meet The Ever-Increasing Demand For Animal Products. Higher Livestock Productivity, However, Should Be Sought Through Better Use Of Locally Available Feed Resources. Crop Residues, Agro-Industrial By-Products And Animal Wastes, Which Are Available In Appreciable Quantities, Can Play A Significant Role In The Nutrition Of Ruminants. The Purpose Of This Book Is To Assist Researchers In Developing Countries, To Develop Livestock Feeding Systems Based On The Available Resources Which Are Mainly Crop Residues, Dry And/Or Mature Pasutres And Agro-Industrial By-Products.

Download or read book Genetic Enhancement of Sorghum and Millet Residues Fed to Ruminants written by Patricia Kristjanson and published by ILRI (aka ILCA and ILRAD). This book was released on 1999-01-01 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimated present value (US$42 million) of the proposed ILRI/ICRISAT/NARS collaborative research project on genetic improvement of millet and sorghum crop residues indicates fairly attractive returns, even with the cautious assumption made about likely adoption rates and the scope of the benefits (i.e. only meat and milk production in cattle in India). The estimated IRR to this research investment (28%) can be compared to market rates on alternative investments. Most longer-run, low-risk, private-sector investments yield rates of return three times as high as alternative investments. However, this raises the question of what is an appropriate rate of return to expect from 'public'good' type of investment such as the investment in international development oriented research. The same methodological approach was recently used (Kristjanson et al 1999) to estimate potential returns to a similary challenging crop-livestock research area, a vaccine against potential returns to a similarly challenging crop-livestock research area, a vaccine against trypanosomosis (a serious livestock disease that poses the greatest development constraint to mixed livestock-crop systems across Africa). Potential returns to this research were estimated at US$ 118 million, with an IRR of 25%, and a benefit:cost ratio of 15:1. In a comparison of predicted rates of return across 5 crop-livestock related research areas at ILRI, potential research benefits were estimated to outweigh the costs of the research by between 9 and 37 times. Returns of similar magnitudes have also been estimated for other crop improvement research. In an economic analysis of returns to 15 research themes at the Centro International de la Papa (CIP) the NPVs ranged from US$ 1 million to US$ 195 million (average US$ 67 million), with IRRs ranging from 13% to 51% (Walker and Collion 1997). ICRISAT ranked returns to 110 different research areas as part of their research priority-setting process several years ago. The average NPV, net benefit:cost ratio and IRR for the top 20 of those were US$ 61 million (with a range from US$ 8 million to US$ 265 million), 52:1 and 39%, respectively (Kelley et al 1995). Thus it appears that the magnitude of returns predicted in this study are very much in line with returns to similar research investments.
Download or read book Rainfed Farming Systems written by Philip Tow and published by Springer Science & Business Media. This book was released on 2011-09-16 with total page 1324 pages. Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Book excerpt: Recent changes in the Conservation Compliance Plans for farmers shows the need for improved information on the effective management of crop residues. Residue management requires an understanding of the crop, soil, and climate in which the farming system is located. In this volume, the strategies for effective residue management are described for each region of the country to provide a comparison of the regional differences. The chapters not only describe the knowledge in each region but also suggest some of the needed areas of research required to develop an improved understanding of the processes involved in effective residue management.

Download or read book Toward Sustainable Agricultural Systems in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
