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.

Migration is not new. In recent decades however, human mobility has increased in numbers and scope and has helped fuel a global shift in the human population from predominantly rural to urban. Migration overall is a livelihood, investment and resilience strategy. It is affected by changes across multiple sectors and at varying scales and is affected by macro policies, transnational networks, regional conditions, local demands, political and social relations, household options and individual desires. Such enhanced mobility, changes in populations and communities in both sending and receiving areas, and the remittances that mobility generates, are key elements of current transitions that have both direct and indirect consequences for forests. Because migration processes engage with rural populations and spaces in the tropics, they inevitably affect forest resources through changes in use and management. Yet links between forests and migration have been overlooked too often in the literature on migration as well as in discussions about forest-based livelihoods. With a focus on landscapes that include tropical forests, this paper explores trends and diversities in the ways in which migration, urbanization and personal remittances affect rural livelihoods and forests.

While deforestation continues at an alarming rate around the world, discussions on the range of underlying causes continue. The premise is that studying successful transitions from deforestation to sustainable forestry ex post in Finland can provide novel insights into how deforestation in the tropics might be reduced in the future. Our fundamental question here is why Finland succeeded to stop deforestation for a century ago and why not the same is feasible in the contemporary tropical countries? This book presents a novel integrated theory within which this case study on Finland and contemporary modeling of underlying causes of tropical deforestation are developed. Finland remains the world’s second largest net exporter of forest products, while maintaining the highest forest cover in Europe. A transition from deforestation to sustainable industrial forestry took place in Finland during the first part of the 20th century. The underlying causes of this transition are compared via our theory with deforestation in 74 contemporary tropical countries. Both appear similar and support our theory. The interaction of public policies and market institutions has appeared to be critical during this transition. The study’s findings suggest that private forest ownership with a continuous increase in the real value of forests and alleviation of poverty under non-corruptive conditions has been a necessary, but not a sufficient, condition for this transition. In a parallel way public policies have also proved to be a necessary, but not sufficient, condition in this transition. The conclusion is that socialistic forestry along with corruption is artificially maintaining too low values in the tropical forests. The opportunity cost of sustainable forestry remains too high and deforestation by extensification of agriculture therefore continues. The prevailing socialistic forestry with dominating public forest ownership is by purpose maintaining administratively set low stumpage prices leading to low value of forests, wide corruption and continuous forest degradation and deforestation. An effective remedy – to raise the value of forests - is found to be within forestry.

Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

Malaysia is one of the world's most biologically diverse regions, but in recent years vast tracts of its forests have been cleared or degraded, with serious human and environmental consequences. Vanishing Rain Forests explores four closely related themes: first it describes the country's forests and the remarkable abundance and diversity of their flora and fauna; secondly, it outlines the processes and policies by which human activity has altered these forests since the early nineteenth century; thirdly, it examines some of the environmental, biological, and cultural consequences of such changes both past and present; and finally, it looks at what has been done to conserve the region's natural wealth and recommends changes that could put Malaysia on the path to a more sustainable future. Throughout the book, the need for a historical perspective is underscored. Environmentalists, biogeographers, botanists and others will find this monograph a cogent assessment of the challenges currently facing rain forest ecology.

In 1972, The Limits to Growth introduced the idea that world resources are limited. Soon after, people became aware of the threats to the world’s rainforests, the biggest terrestrial repositories of biodiversity and essential regulators of global air and water cycles. Since that time, new research and technological advances have greatly increased our knowledge of how rainforests are being affected by changing patterns of resource use. Increasing concern about climate change has made it more important than ever to understand the state of the world’s tropical forests. This book provides an up-to-date picture of the health of the world’s tropical forests. Claude Martin, an eminent scientist and conservationist, integrates information from remote imaging, ecology, and economics to explain deforestation and forest health throughout the world. He explains how urbanization, an increasingly global economy, and a worldwide demand for biofuels put new pressure on rainforest land. He examines the policies and market forces that have successfully preserved forests in some areas and discusses the economic benefits of protected areas. Using evidence from ice core records and past forest cover patterns, he predicts the most likely effects of climate change. Claude Martin brings his wealth of experience as an ecologist, director of the WWF, and advistor to various conservation organizations to bear on the latest research from around the world. Contributions from eight leading experts provide additional insight.
