The arrival of western science and economic interests to the tropics has dramatically changed the tropical environment and its ecology. Environmental Management in the Tropics discusses the ecology of the tropics and examines how it is different from the temperate zone where western science evolved. The author discusses how native people traditionally subsisted in different ecological zones of the tropics and how they rationalized their relationship. The author also takes a critical look at the impact of colonialism in the tropics and how it changed traditional cultures and their relationship with the environment. The current clash between economics and ecology in the tropics is explored in depth. According to the author, we are now able to draw "a line in the sand" and illustrate the consequences of continuing current practices. Environmental Management in the Tropics shows how this situation developed and discusses how the two opposing concepts must be brought back into harmony. The book is one of the few studies to take a truly interdisciplinary approach combining the serious inevitabilities of natural science with the variables of history, culture, politics, and economics. It gives us a new respect for the past and tradition of the tropics and clearly spells out why dramatic changes must occur to prevent further degradation of the tropical environment. Environmental Management in the Tropics is an important reference for ecologists, conservationists, scientists, researchers, environmental consultants, land managers and developers, members of the world regulatory community, and anyone working on projects in tropical regions.

Throughout the world people are concerned about the demise of tropical forests and their wildlife. Hunting by forest-dwelling people has a dramatic effect on wildlife in many tropical forests, frequently driving species to local extinction, with devastating implications for other species and the health of the forests themselves. But wildlife is an important source of protein and cash for rural peoples. Can hunting be managed to conserve biological communities while meeting human needs? Are hunting rates as practiced by tropical forest peoples sustainable? If not, what are the biological, social, and cultural implications of this failure? Answering these questions is ever more important as national and international agencies seek to integrate the development of local peoples with the conservation of tropical forest systems and species. This book presents a wide array of studies that examine the sustainability of hunting as practiced by rural peoples. Comprising work by both biological and social scientists, Hunting for Sustainability in Tropical Forests provides a balanced viewpoint on the ecological and human aspects of this hunting. The first section examines the effects of hunting on wildlife in tropical forests throughout the world. The next section looks at the importance of hunting to local communities. The third section looks at institutional challenges of resource management, while the fourth draws on economic perspectives to understand both hunting and sustainability. A final section provides synthesis and summary of the factors that influence sustainability and the implications for management. Drawing on examples from Ecuador to Congo-Zaire to Sulawesi, Hunting for Sustainability in Tropical Forests will be a valuable resource to policymakers, conservation organizations, and students and scholars of biology, ecology, and anthropology.

Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.

Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

This fully updated third edition of the classic text, widely cited as the most important and useful book for health engineering and disease prevention, describes infectious diseases in tropical and developing countries, and the effective measures that may be used against them. The infections described include the diarrhoeal diseases, the common gut worms, Guinea worm, schistosomiasis, malaria, Bancroftian filariasis and other mosquito-borne infections. The environmental interventions that receive most attention are domestic water supplies and improved excreta disposal. Appropriate technology for these interventions, and also their impact on infectious diseases, are documented in detail. This third edition includes new sections on arsenic in groundwater supplies and arsenic removal technologies, and new material in most chapters, including water supplies in developing countries and surface water drainage.

"Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.
