Stability of Tropical Rainforest Margins


Book Description

Tropical rainforests are disappearing at an alarming rate, causing unprecedented losses in biodiversity and ecosystem services. This book contributes to an improved understanding of the processes that have destabilizing effects on ecological and socio-economic systems of tropical rain forest margins, as well as striving to integrate environmental, technological and socio-economic issues in their solution.




Tropical Forests


Book Description

Large regions of the planet have been transformed from their natural composition into different human-made landscapes (farmlands, forest plantations, pastures, etc.). Such process, called land use change, is one of the major components of the current global change, which has brought the planet into a new geological era: the Anthropocene. Land use change is particularly important in tropical forests, as this ecosystem type is still heavily affected by deforestation for timber extraction, agricultural land creation of urban expansion. Changing land use has important implications for the services that tropical forests provide: production of goods such as timber, food or water; regulation of process such as nutrient cycling, carbon sequestration, local weather or climate extremes; generating the framework for economic and cultural activity, etc. Therefore, keeping ecosystem services when changing the use of the tropical lands is a major challenge in tropical regions. This brief book, by showcasing different research work done in tropical countries, provides a first introduction on this topic, discussing issues such as biodiversity loss, changes in local weather or nutrient cycling patterns, and economic activities around tropical forests, and tools to detect and quantify the importance of land use change.




Managing the Future of Southeast Asia's Valuable Tropical Rainforests


Book Description

This book provides current knowledge about tropical rain forest genetics and its implications for the profitable and sustainable management of forest resources in Southeast Asia. Each chapter covers a major topic in the evolutionary biology of tropical rain forest trees and how management systems interact with these natural dynamics. Authors provide an up-to-date and insightful review of important scientific findings and conclude with practical recommendations for the modern forester in Southeast Asia. Several chapters provide compelling discussions about commonly neglected aspects of tropical forestry, including the impact of historical dynamics of climate change, anthropogenic threats to genetic viability, and the important role of wildlife in maintaining genetic diversity. These discussions will promote a deeper appreciation of not only the economic value of forests, but also their mystery and intangible values. The silvicultural industry in Southeast Asia is a major contributor to the regional economy but the connection between scientific research and the application and development of policy could be improved upon. This book will help bridge that gap. This book will prove beneficial reading for forestry students, professional forest managers, and policy makers, who do not have technical training in genetics. It is also intended for non-specialists who are involved in the tropical timber industry, from the local forest manager to the international timber purchasing agent.




Forests, Water and People in the Humid Tropics


Book Description

Forests, Water and People in the Humid Tropics is a comprehensive review of the hydrological and physiological functioning of tropical rain forests, the environmental impacts of their disturbance and conversion to other land uses, and optimum strategies for managing them. The book brings together leading specialists in such diverse fields as tropical anthropology and human geography, environmental economics, climatology and meteorology, hydrology, geomorphology, plant and aquatic ecology, forestry and conservation agronomy. The editors have supplemented the individual contributions with invaluable overviews of the main sections and provide key pointers for future research. Specialists will find authenticated detail in chapters written by experts on a whole range of people-water-land use issues, managers and practitioners will learn more about the implications of ongoing and planned forest conversion, while scientists and students will appreciate a unique review of the literature.




Changes and Disturbance in Tropical Rainforest in South-East Asia


Book Description

Views on the dynamics of tropical forests are changing rapidly with the recognition that their environment is variable on the decadal to century scale. Fluctuating climatic conditions partly determine tropical forest structure, species composition and dynamics. Tropical communities are also highly contingent in space and time with respect to site and historical factors. Tropical forests have experienced to some degree this disturbance regime in the past, but climatologists are now predicting increasingly frequent extreme events in the new century. The combination of increasing deforestation and land-use conversion by man plus an increasingly variable environment means a situation that could be very difficult to manage.




Tropical Rainforests and Agroforests under Global Change


Book Description

not only for land use systems that depend on the regular supply of rain or irrigation water but also for the future development of natural rainforests as drought stress has been shown to a?ect tree growth and species composition in old-growth forests (Wright 1991, Walsh and Newbery 1999, Engelbrecht et al. 2007). A drought experiment conducted in a cacao agroforestry plantation showed that this plantation was surprisingly resilient to an induced drought of more than a year (Schwendenmann et al. 2009). However, droughts can have a strong impact on household incomes from agriculture, they strongly a?ect the vulnerability to poverty and thus have to be analyzed as important exogenous shocks to households, forcing them to adjust their behaviour and develop strategies to cope with these problems. The stability of rainforest margins is a critical factor in the protection of tropical rainforests (Tscharntke et al. 2007). At present, however, rainf- est margins in many parts of the tropics are far from stable, both in soc- economic and in ecological terms. For example, protected areas may attract, rather than repel, human settlement, which may be due to international donor investment in national conservation programs (Wittemeyer et al. 2008). An alternative hypothesis is that protected areas might be compromised if leakage takes place, that is, if impacts that would take place inside the restricted area are displaced to a nearby, undisturbed area (Ewers and Rodrigues 2008).




Tropical Rain Forest Ecology, Diversity, and Conservation


Book Description

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.




Environmental Change in South-East Asia


Book Description

Environmental Change in South-East Asia brings together scholars, journalists, consultants and NGO activists to explore the interaction of people, politics and ecology. Ostensibly "green" activities - plantation forestry, eco-tourism, hydro-electricity - are revealed as guises used by elites to promote their own political and economic interests. Highlighting fatal flaws in presently exclusive economic and ecological approaches, the authors stress that neither the quest for sustainable development nor the process of environmental change itself can be understood without reference to political processes.
