The Social Ecology of Tropical Forests


Book Description

The Social Ecology of Tropical Forests brings together various analyses from the three major tropical regions-Southeast Asia, the Amazon basin, and Sub-Saharan Africa-and by challenging simplistic correlations, the authors explore the complex relationships between deforestation and migration. The book provides both an historical overview of migration into these regions, and presents contemporary case studies to reveal the complex interplay of factors motivating migration. The scope of the discussion is extensive, covering historical issues such as the impact of the slave trade on Sub-Saharan African forests and communities, and contemporary dilemmas like the over-exploitation of natural forest products in Vietnam. The authors look at the broader picture of intertwining political, social, geographical, environmental, and historical influences, without seeking quick-fix solutions to the social and environmental issues arising from increasing forest cover loss. The analyses are spatially and temporally contextualized, drawing on both qualitative and quantitative data to provide a useful resource for studying the societies of tropical regions and their social ecology.




Tropical Forest Community Ecology


Book Description

Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Tropical Forests: Management and Ecology


Book Description

Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.




Seasonally Dry Tropical Forests


Book Description

Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.




The Political Ecology of Tropical Forests in Southeast Asia


Book Description

Following an interdisciplinary approach to debates about the future of tropical forests in Southeast Asia, the authors - experts in their field - unravel the extent to which the interests of local inhabitants, nation-states and international environmental movements are intertwined. This volume, a joint publication with Kyoto University Press, examines the highly politicized context in which local forestry problems intersect with global market forces, focusing on the social and economic diversity of different tropical forests and their specific historical background. It emphasizes the importance of examining local issues in their own right.




The Social Lives of Forests


Book Description

Forests are in decline, and the threats these outposts of nature face—including deforestation, degradation, and fragmentation—are the result of human culture. Or are they? This volume calls these assumptions into question, revealing forests’ past, present, and future conditions to be the joint products of a host of natural and cultural forces. Moreover, in many cases the coalescence of these forces—from local ecologies to competing knowledge systems—has masked a significant contemporary trend of woodland resurgence, even in the forests of the tropics. Focusing on the history and current use of woodlands from India to the Amazon, The Social Lives of Forests attempts to build a coherent view of forests sited at the nexus of nature, culture, and development. With chapters covering the effects of human activities on succession patterns in now-protected Costa Rican forests; the intersection of gender and knowledge in African shea nut tree markets; and even the unexpectedly rich urban woodlands of Chicago, this book explores forests as places of significant human action, with complex institutions, ecologies, and economies that have transformed these landscapes in the past and continue to shape them today. From rain forests to timber farms, the face of forests—how we define, understand, and maintain them—is changing.




Tropical Forest Ecosystems Structure and Function


Book Description

Tropical forests are vital for social, economic and ecological reasons. They play an important role in ecosystem processes [ such as the biogeochemical and hydrological cycle ] they provide habitat for wildlife and serve as source of biodiversity and they offer protection against soil erosion [Kremen et al., 2000 and Condit et al., 2002]. The forest contains large trees standing, 30 to 50 meters in height, creating continuous canopy of foliage. The enclosed canopy, shades tree forest floor, inhibiting the development of much undergrowth, creating an open forest formation. Piercing into the tree canopy, reveals a multistory appearance of broad leaf, evergreen vegetation. The forest is a treasure trove of different animal and plant species. Forest and woodlands cover nearly 40% of the earth’s land surface and they are the most biologically diverse ecosystems in most part of the world. The tropics consist of a diversity, occurring between the latitudes of the tropic of Cancer and the tropics of Capricon, north and south of the equator. These ecosystems are currently experiencing the highest rates of destruction in the world. More than 90% of dry forests have been destroyed and less than 2% of what remains is protected. Because of the climatic and forest structure, dry forests are easier to clear for agriculture, the soil is more fertile and the land is more suitable for livestock. Forest area has increased slightly since 1980 in industrial countries, but, has declined by almost 10% in developing countries. Tropical deforestation probably exceeds 1,30,000 sq. km a year. Less than 40% of forest globally are relatively undisturbed by human action. Many developing countries today, rely on timber for export earnings, at the same time; millions of people in tropical countries still depend on forests to meet their every need. Since time immemorial, forest has provided a valuable source of economic life for human populations. Yet, the ways in which, forests are used and valued, depends largely on people’s economic needs and priorities in a particular place or at a particular time, balanced against the relative scarcity or abundance of forest resources. Over recent years, a complex array of social, economic and political changes have altered human demands on forest. These changing demands have had devastating impact on forest status and integrity. This book is an outcome of the own work, experience and research on tropical forest for the last 30 years. I hope, this will provide to readers, concise, sufficient and recent information on tropical forest of the world.




Tropical Forests in Transition


Book Description

In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.
