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 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.

Download or read book Voice of the Marketplace written by Joseph A. Pratt and published by Texas A&M University Press. This book was released on 2002 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Petroleum Council (NPC) emerged out of the close cooperation between the petroleum industry and the federal government during World War II. An industry-financed advisory committee designed to work closely with the Department of the Interior, it enjoyed a remarkable independence from political or financial pressures. Including representatives of all phases of the petroleum business, the NPC could reach deep within the industry for information on vital issues. In the last fifty-plus years, the Council has evolved into a voice of the marketplace, analyzing conditions in the petroleum industry at the request of the government and publishing its findings in reports widely considered authoritative and useful. Three uniquely qualified historians here chronicle the development and contributions of the NPC to both the energy industry and the American market. While technological advances, skyrocketing world demand, the rise of OPEC, and far-reaching regulatory initiatives have fundamentally transformed the petroleum industry's structure and operating environment, the National Petroleum Council has remained a reliable source of authoritative information. Joseph A. Pratt, William H. Becker, and William McClenahan, Jr., analyze the choices and strategies that have given the Council the adaptability and resilience to survive and remain important. The authors look also at the actual reports generated by the Council--more than two hundred studies to date--and the impact they have had on both government and business. They examine the NPC's ability to tap information and personnel from all sectors of the industry and to fund from industry resources studies that would have exceeded the pockets of the federal government. They consider the way the Council has managed to encompass the varied viewpoints within a diverse, highly competitive industry, and particularly to bridge the sharp historical division between the "majors" and the "independents." Finally, the authors analyze the one political concern that has remained constant for the industry: antitrust. This engagingly written book not only sheds light on the petroleum industry and its regulatory context, but also addresses the larger questions of the U.S. government's relations with the industries it regulates.

Download or read book Rural Wealth Creation written by John L. Pender and published by Routledge. This book was released on 2014-06-05 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the role of wealth in achieving sustainable rural economic development. The authors define wealth as all assets net of liabilities that can contribute to well-being, and they provide examples of many forms of capital – physical, financial, human, natural, social, and others. They propose a conceptual framework for rural wealth creation that considers how multiple forms of wealth provide opportunities for rural development, and how development strategies affect the dynamics of wealth. They also provide a new accounting framework for measuring wealth stocks and flows. These conceptual frameworks are employed in case study chapters on measuring rural wealth and on rural wealth creation strategies. Rural Wealth Creation makes numerous contributions to research on sustainable rural development. Important distinctions are drawn to help guide wealth measurement, such as the difference between the wealth located within a region and the wealth owned by residents of a region, and privately owned versus publicly owned wealth. Case study chapters illustrate these distinctions and demonstrate how different forms of wealth can be measured. Several key hypotheses are proposed about the process of rural wealth creation, and these are investigated by case study chapters assessing common rural development strategies, such as promoting rural energy industries and amenity-based development. Based on these case studies, a typology of rural wealth creation strategies is proposed and an approach to mapping the potential of such strategies in different contexts is demonstrated. This book will be relevant to students, researchers, and policy makers looking at rural community development, sustainable economic development, and wealth measurement.
