Ausgehend von einer Analyse der Krise der globalen Biosphäre und ihrer Bedeutung für eine nachhaltige Entwicklung leiten die Wissenschaftler Prinzipien für eine erfolgreiche internationale "Biosphärenpolitik" ab. Der Beirat geht von dem Ansatz aus, daß Erhaltung und nachhaltige Nutzung der Biosphäre integriert betrachtet werden müssen. Es wird Politikberatung zu einer breiten Palette von Themen geboten: von der Bioprospektierung bis zu einer nachhaltigen Landnutzung, vom bioregionalen Management bis zum Naturschutz, von der Bekämpfung des Raubbaus an Naturressourcen bis zur Erdsystemanalyse. Besonderes Gewicht liegt auf Empfehlungen zur Weiterentwicklung der Biodiversitätskonvention, der internationalen wissenschaftlichen Politikberatung, der Biosphärenforschung und der finanziellen Rahmenbedingungen für Biosphärenpolitik.

During the next twenty to twenty-five years, the global human population will most likely exceed eight billion. Whether the earth's resources can support this unprecedented population increase remains an open question. The papers collected here examine one facet of this question by assessing the production potential of available land in relation to the predicted demand for food. The authors describe in detail current pressures on land and water resources; the effects of climate on productivity; the need for crop improvement and better management of water, soil and nutrients; economic factors; and environmental limitations. They also provide practical suggestions for guaranteeing adequate supplies of food in the future. The papers were developed from a meeting of the Royal Society in London in December 1996 and a follow-up meeting hosted by the Ciba Foundation in London, and they were previously published as an issue of The Philosophical Transactions of the Royal Society of London.

Agroforestry for soil management

Author: Anthony Young

Publisher: CABI

Agroforestry refers to land use systems in which trees or shrubs are grown in association with agricultural crops, or pastures and livestock. From its inception, it has contained a strong element of soil management. Well-designed and managed agroforestry systems have the potential to control run-off and erosion, maintain soil organic matter and physical properties, and promote nutrient cycling. By these means, agroforestry can make a major contribution to sustainable land use. The previous edition of this book, entitled Agroforestry for Soil Conservation(1989), was based on indirect evidence from agriculture, forestry and soil science. The present work provides a new synthesis, drawing on over 700 published sources dating largely from the 1990s. These include both results of field trials of agronomy systems, and research into the plant-soil processes which take place within them. Soil conservation in its narrower sense, the control of erosion, is treated alongside other equally important aspects of soil management, such as nutrient cycling. The new edition summarizes the present state of knowledge and indicates needs for research. It is essential reading for all concerned with agroforestry, whether as students, research scientists, or for practical purposes of development. It is also of interest to soil scientists, agronomists and foresters.

World population is increasing by some 80 million a year, largely in developing countries. Can the food requirements of this growing population be met? How can the limited resources of available land be sustainably managed? Where are the worst areas of land degradation to be found? Why are soils a major element of the environment? Thin on the Ground seeks to answer these questions by reviewing the successive stages of tropical soils research: soil survey, land evaluation, land use planning, and the evolution of earlier attempts the check soil erosion into the current approach of conservation agriculture. Priorities for today should be soil health monitoring, and linking modern methods of conservation with agricultural advisory services. The author's contention that population policy should be an integral part of agricultural development will not pass unchallenged. Includes 38 photographs, many of historical importance. "An authoritative and informative overview of soil survey activities in the developing world." WOSSAC: World Soil Survey Archive and Catalogue. From reviews of the First Edition: "A well-documented, lively and informative description.....The author has a magnificent capacity to synthesize large amounts of information from different disciplines.....Gives a strong sense of excitement....A remarkable and valuable book for anyone concerned with third world development." Anthony Young has over 40 years experience of all aspects of tropical soils, extending from survey and evaluation to conservation and management. As an early member of the World Agroforestry Centre he was the first to establish the potential of agroforestry in soil management. He has published 15 books, notably the comprehensive review, Land Resources: Now and for the Future, and has been awarded doctorates by the Universities of Sheffield and East Anglia.

In Crossing the Next Meridian, Charles F. Wilkinson, an expert on federal public lands, Native American issues, and the West's arcane water laws explains some of the core problems facing the American West now and in the years to come. He examines the outmoded ideas that pervade land use and resource allocation and argues that significant reform of Western law is needed to combat desertification and environmental decline, and to heal splintered communities. Interweaving legal history with examples of present-day consequences of the laws, both intended and unintended, Wilkinson traces the origins and development of the laws and regulations that govern mining, ranching, forestry, and water use. He relates stories of Westerners who face these issues on a day-to-day basis, and discusses what can and should be done to bring government policies in line with the reality of twentieth-century American life.

Preserving Public Lands for the Future

The Politics of Intergenerational Goods

Comparing national efforts to preserve public lands, William R. Lowry investigates how effectively and under what conditions governments can provide goods for future generations. Providing intergenerational goods, ranging from balanced budgets to space programs and natural environments, is particularly challenging because most political incentives reward short-term behavior. Lowry examines the effect of institutional structure on the public delivery of these goods. He offers a theoretical framework accounting for both the necessary conditions — public demand, political stability, and official commitment to long-term delivery — and constraining factors — the tensions between public agencies and politicians as well as between different levels of government — that determine the ability of a nation to achieve long-term goals. In support of this argument, Lowry evaluates data on park systems from more than one hundred countries and provides in-depth case studies of four — he United States, Australia, Canada, and Costa Rica — to show how and why the delivery of intergenerational goods can vary. For each of the cases, he reviews background information, discusses constraints on agency behavior, and assesses expansion of the park systems and restoration of natural conditions at specific locations. This extensive comparative analysis of the preservation of public lands offers new insights into the capability of nations to pursue long-term goals.
