Available in PDF, EPUB and Kindle. Book excerpt: The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.

Download or read book Challenges and Strategies of Dryland Agriculture written by S.C. Rao and published by Scientific Publishers. This book was released on 2011-01-01 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world has made remarkable progress in maintaining adequate food supplies during the past quarter century by introducing yield-increasing technologies such as better genetics, crop protection products, and more efficient use of fertilizers and irrigations. Far more people depend on irrigation in the modern world than during the times of ancient Sumeria. The spread of irrigation has been the key factor in increasing global crop yields. But future scarcity present the single biggest threat to future food production. The shift of water from agriculture to the growing cities and industry almost certainly will impact global food production. This means that dryland agriculture will be increasingly important in meeting food requirement for the growing population. Advaces in plant genetics and agronomic conservation technologies, when considered in concert, continue to provide the greatest opportunities to achieve sustainability and profitability in dryland agriculture and will continue to be the focus of the ARS research program. The ARS is please to join the crop Science Society of America and international center for Agriculture Research in Dry Areas (ICARDA) in sponsoring a symposium “Challenges and strategies for Dryland Agriculture” at the Trisocieties Annual Meeting in November 2002 at Indianapolis, IN. This special publication contains an impressive series of paper by international group of experts on dryland agricultural production, conservation, and policy. The principles, philosophies, and technologies presented in this publication have the potential to contribute to improve food security and livelihoods for the people in dryland regions of the world.
Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Download or read book Global Challenges For Future Food And Agricultural Policies written by David Blandford and published by World Scientific. This book was released on 2019-01-10 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current and future challenges facing the food and agricultural system and their implications for policymaking at the national and international level.The growth in global population and income is expected to result in increasing demand for food and agricultural raw materials, intensifying concerns over food security and increasing pressure on the planet's natural resources. Moreover, climate change — a challenge on its own — is likely to increase the urgency for reforms in the food and agricultural sector. As a substantial contributor to greenhouse gas emissions, the sector will need to participate in efforts to slow global warming and to adjust to the effects of climate change, while ensuring global food security and resource sustainability. These pressures define a new set of priorities for policymaking at the national and international level. They also necessitate changes in the framework of global institutions for effective governance of the food system.Global Challenges for Future Food and Agricultural Policies presents a comprehensive analysis of the inter-related policy challenges of food security, management of natural resources, climate change, and international governance. The book also offers valuable insights into options for effective policymaking with the goal of inducing positive policy changes to the food and agricultural sector.

Download or read book Soil Organic Carbon and Feeding the Future written by Rattan Lal and published by CRC Press. This book was released on 2022-01-18 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) is a highly reactive constituent of the soil matrix because of its large surface area, high ion exchange capacity, enormous affinity for water due to hygroscopicity, and capacity to form organo-mineral complexes. It is an important source and sink of atmospheric CO2 and other greenhouse gases depending on climate, land use, soil and crop management, and a wide range of abiotic and biotic factors, including the human dimensions of socioeconomic and political factors. Agroecosystems are among important controls of the global carbon cycle with a strong impact on anthropogenic or abrupt climate change. This volume of Advances in Soil Sciences explains pedological processes set-in-motion by increases in SOM content of depleted and degraded soils. It discusses the relationship between SOM content and critical soil quality parameters including aggregation, water retention and transport, aeration and gaseous exchange, and chemical composition of soil air. The book identifies policy options needed to translate science into action for making sustainable management of SOM as a strategy for adaptation to and mitigation of climate change. Features: Relates soil organic matter stock to soil processes, climate parameters, vegetation, landscape attributes Establishes relationships between soil organic matter and land use, species, and climate Identifies land use systems for protecting and restoring soil organic matter stock Links soil organic matter stock with the global carbon cycle for mitigation of climate change Part of the Advances in Soil Sciences series, this volume will appeal to agricultural, environmental, and soil scientists demonstrating the link between soil organic matter stock and provisioning of critical ecosystem services for nature and humans.
Download or read book The Future of Drylands written by Cathy Lee and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.

Download or read book Strangers in Paradise written by Daniel Simberloff and published by Island Press. This book was released on 1997-04 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive nonindigenous species -- plants and animals that have been introduced to an ecosystem from someplace else -- are wreaking havoc around the globe. Because they did not co-evolve with species already in the ecosystem, they can profoundly disturb species interactions and ecosystem function.The state of Florida has one of the most severe exotic species problems in the country; as much as a quarter of many taxa in Florida are nonnative, and millions of acres of land and water are dominated by nonindigenous species. Strangers in Paradise provides an in-depth examination of the Florida experience and of the ongoing efforts to eradicate or manage introduced species. Chapters consider: natural disturbance and the spread of nonindigenous species case studies of insects, freshwater invertebrates, fishes, amphibians and reptiles, birds, marine invertebrates and algae, and mammals methods of managing nonindigenous species including ecological restoration, eradication, "maintenance control," and biological control management on public lands the regulatory framework including the role of the federal government as well as state authorities and responsibilities Strangers in Paradise is the first comprehensive volume to address a large, diverse region and the full range of nonindigenous species, the problems they cause, and the methods and impediments to dealing with them. Throughout, contributors emphasize solutions and relate the situation in Florida to problems faced by other states, making the book an important guide for anyone involved with control and management of invasive species.
