Toward Sustainable Agricultural Systems in the 21st Century PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309148960
Category : Technology & Engineering
Languages : en
Pages : 598

Book Description
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.

Publisher: World Bank Publications
ISBN: 9780821325100
Category : Technology & Engineering
Languages : en
Pages : 64

Book Description
The productivity growth of farming in Asian countries over the past few decades highlights the high returns on investments in agricultural research and extension made in the region. This publication examines the performance of agricultural research and extension programmes in Asia, including the World Bank's training and visit (TandV) system, the challenges they face, and ways of improving their relevance, responsiveness, and cost- effectiveness. Conclusions reached include the importance of raising agricultural productivity through new technology in order to promote long- term growth and poverty reduction, and the need for less intensive and more environmentally sound agricultural practices.

Languages : en
Pages : 408

Book Description
Learn to integrate molecular genetic techniques with traditional plant breeding methods!This comprehensive book provides the latest authoritative scientific information on improvement of both temperate and tropical crops. Crop Improvement: Challenges in the Twenty-First Century brings together expert plant breeders and geneticists to address issues related to crop adaptability and stability across environments for important food and fiber crops. It emphasizes the need to integrate molecular genetic techniques with traditional plant breeding methods to develop hardier, more productive crops. Crop Improvement includes the latest research on physiological and biochemical responses of plants to drought and heat stress, which should help breeders develop effective strategies for improving resistance to abiotic stresses. In addition, this helpful book elucidates the use of mixed models and best linear unbiased prediction. To make the book comprehensive, chapters discuss stability analysis in crop performance trials and genotype-by-environment interactions.Crop Improvement includes detailed information on breeding specific crops, including: rice tropical maize sorghum common bean sugar beet bananas and plantain cotton Crop Improvement offers both practical information and up-to-date research. It also suggests a vision of new directions and partnerships that are expected to evolve in this century. This book is an essential resource for practicing plant breeders and geneticists at universities, government agencies, and industry. It should also be of use to teachers and students engaged in crop breeding.

Feeding the World

Feeding the World PDF Author: Vaclav Smil
Publisher: MIT Press
ISBN: 9780262692717
Category : Science
Languages : en
Pages : 396

Book Description
A realistic yet encouraging look at how society can change in ways that will allow us to feed an expanding global population. This book addresses the question of how we can best feed the ten billion or so people who will likely inhabit the Earth by the middle of the twenty-first century. He asks whether human ingenuity can produce enough food to support healthy and vigorous lives for all these people without irreparably damaging the integrity of the biosphere. What makes this book different from other books on the world food situation is its consideration of the complete food cycle, from agriculture to post-harvest losses and processing to eating and discarding. Taking a scientific approach, Smil espouses neither the catastrophic view that widespread starvation is imminent nor the cornucopian view that welcomes large population increases as the source of endless human inventiveness. He shows how we can make more effective use of current resources and suggests that if we increase farming efficiency, reduce waste, and transform our diets, future needs may not be as great as we anticipate. Smil's message is that the prospects may not be as bright as we would like, but the outlook is hardly disheartening. Although inaction, late action, or misplaced emphasis may bring future troubles, we have the tools to steer a more efficient course. There are no insurmountable biophysical reasons we cannot feed humanity in the decades to come while easing the burden that modern agriculture puts on the biosphere.

Farming Systems Research into the 21st Century: The New Dynamic

Farming Systems Research into the 21st Century: The New Dynamic PDF Author: Ika Darnhofer
Publisher: Springer Science & Business Media
ISBN: 9400745036
Category : Technology & Engineering
Languages : en
Pages : 488

Book Description
Farming Systems Research has three core characteristics: it builds on systems thinking, it depends on the close collaboration between social and biophysical sciences, and it relies on participation to build co-learning processes. Farming Systems Research posits that to contribute towards sustainable rural development, both interdisciplinary collaborations and local actor engagement are needed. Together, they allow for changes in understanding and changes in practices. This book gives an overview of the insights generated in 20 years of Farming Systems Research. It retraces the emergence and development of Farming Systems Research in Europe, summarises the state-of-the-art for key areas, and provides an outlook on new explorations, especially those tackling the dynamic nature of farming systems and their interaction with the natural environment and the context of action.

Book Description
Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.
