Book Description
Farming and the Fate of Wild Nature addresses an urgent and complex issue facing communities and cultures throughout the world: the need for heightened land stewardship and conservation in an era of diminishing natural resources. Agricultural lands in rural areas are being purchased for development. Water scarcities are pitting urban and development expansion against agriculture and conservation needs. The farming population is ageing and retiring, while those who remain struggle against low commodity prices, international competition, rising production costs, and the threat of disappearing subsidies. We are living amidst a major extinction crisis--much of it driven by agriculture--as well as an increasing shift toward a global urban populace. The modern diet, driven by a grain-fed livestock industry, is no longer connected with the ecosystems that support it. In international circles, experts are arguing that further intensification of agriculture (through industrialization and genetic modification) will be necessary to both feed an exploding human population and to save what is left of wild biodiversity. This book takes up where its predecessor, the award-winning Farming with the Wild, left off. Featuring a wide range of in-depth essays, articles, and other materials by such authors as Aldo Leopold, Wendell Berry, Michael Pollan, Fred Kirschenmann, and Daniel Imhoff, this book persuasively demonstrates that farm and ranch operations which coexist with wild nature are necessary to sustain biodiversity and beauty on the landscape. In fact, as this invaluable educational resource demonstrates, they are essential in the challenge of building sane, healthy, and hopeful human societies.

Book Description
Although food-production systems for the world's rural poor typically have had devastating effects on the planet's wealth of genes, species, and ecosystems, that need not be the case in the future. In Ecoagriculture, two of the world's leading experts on conservation and development examine the idea that agricultural landscapes can be designed more creatively to take the needs of human populations into account while also protecting, or even enhancing, biodiversity. They present a thorough overview of the innovative concept of "ecoagriculture" - the management of landscapes for both the production of food and the conservation of wild biodiversity. The book: examines the global impact of agriculture on wild biodiversity describes the challenge of reconciling biodiversity conservation and agricultural goals outlines and discusses the ecoagriculture approach presents diverse case studies that illustrate key strategies explores how policies, markets, and institutions can be re-shaped to support ecoagriculture While focusing on tropical regions of the developing world -- where increased agricultural productivity is most vital for food security, poverty reduction, and sustainable development, and where so much of the world's wild biodiversity is threatened -- it also draws on lessons learned in developed countries. Dozens of examples from around the world present proven strategies for small-scale, low-income farmers involved in commercial production. Ecoagriculture explores new approaches to agricultural production that complement natural environments, enhance ecosystem function, and improve rural livelihoods. It features a wealth of real-world case studies that demonstrate the applicability of the ideas discussed and how the principles can be applied, and is an important new work for policymakers, students, researchers, and anyone concerned with conserving biodiversity while sustaining human populations.

Book Description
An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.

Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Their often rich variety of resources makes them highly valuable to the peoples who live With a few exceptions (like the Everglades in the or regularly stay in them. However, access to them United States), the last remaining large wetlands are to be found in developing countries. Perhaps this can is difficult and those unaware of their services be explained by insufficient financial resources, frequently associate wetlands with such nuisances and calamities as mosquitos, disease, floods, impen lower popUlation density or a different concept of etrable wastelands, etc. As a result these areas are development and well-being. Whatever the reasons, often perceived as obstacles to human development many tropical wetlands still exist and support the and well-being. subsistence of many communities. But for how much History reflects these two views. Wetlands may longer? have been the cradle of great civilizations (like the During the last few decades tropical wetlands Maya, Inca, Aztec, Nilotic and Mesopotamian have also been destroyed or considerably altered. Dams and embankments now prevent water from civilizations), but elsewhere their destruction allowed other societies to develop. For example the Nether spreading into the floodplains of several rivers, like lands literally 'emerged from the waters' thanks to the Senegal, Volta and Nile.

Book Description
The conference "Combating Desertification with Plants" was held in Beer Sheva, Israel, from November 2-5, 1999, and was attended by 70 participants from 30 countries and/or international organisations. Desertification - the degradation of soils in drylands - is a phenomenon occurring in scores of countries around the globe. The number of people (in semiarid regions) affected by the steady decline in the productivity of their lands is in the hundred millions. The measures required to halt and reverse the process of desertification fall into many categories - policy, institutional, sociological-anthropological, and technical. Although technical "solutions" are not currently in vogue, the conference organizers felt that perhaps the pendulum had swung too far in the direction of "participatory approaches." Hence IPALAC - The International Program for Arid Land Crops - whose function is to serve as a catalyst for optimizing the contribution of plant germplasm to sustainable development in desertification-prone regions - felt the time was opportune for providing a platform for projects where the "plant-driven" approach to development finds expression. Some 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and Mechanisms of Plant Transfer. The conference was funded by UNESCO (Division of Ecological Sciences), the Ministry of Foreign Affairs of Finland, and MASHAV, Israel's Center for International Development Cooperation.

Book Description
Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.

Book Description
Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.
