Book Description
The main subject discussed in this study is the way in which the ancient Maya of Calakmul (modern Mexico), who thrived between 900 B.C. to A.D. 1000, managed their landscape in order to survive in the tropical rainforest. Their lithic technology, the hot, humid climate with a prolonged dry season, the lack of permanent surface sources of fresh water, and thin soils, considered insufficient for sustained agricultural production, are factors that were addressed successfully by the Maya in developing their complex civilization. The author's research begins with landscape, archaeological, and edaphological analyses, after which she explores the areas most advantageous to permanent habitation, suitable agricultural zones, land potential of the region and the capability of the area for supporting population. In addition, a complex agricultural channel irrigation system is explored as a critical factor for managing productive terrain for agriculture in karstic depressions (bajos). Similarly, an impressive rain harvesting system is exposed as an option to optimize hydrological resources for canalizing excessive rain during the wet season and storing water during the dry period. Finally, a reconstruction of the agricultural landscape is proposed.

Book Description
Topics covered include the use and conservation of ethnobotanical information, the potential uses of nontimber forest products from various regions of the Neotropics, the development and use of plants as medicines, and the international marketplace for nontimber forest products and how it can best be created and reached. Because of their special significance, a separate section is devoted to uses and potential uses of palm products. Among the contributors are: Al Gentry, Missouri Botanical Garden; Steven R. King, Shaman Pharmaceuticals; Gary Paul Nabhan, Native Seed/SEARCH; Richard Evans Schultes, Botanical Museum of Harvard University; and others from around the globe. Mark Plotkin is vice president for the program in plant conservation, and Lisa Famolare is a program associate at Conservation International, an organization dedicated to the conservation of ecosystems and biological diversity worldwide.

Book Description
Globally rainforests are under threat on numerous fronts, including clearing for agriculture, harvesting for timber and urban expansion. Yet they have a crucial role in biodiversity conservation, climate change mitigation and providing other ecosystem services. As the term is used in this book, rainforests include both temperate and tropical, although the emphasis is on tropical rainforests. Rainforests are also attractive tourist spaces and where they have been used as a tourism resource have generated significant income for local communities. However not all use of rainforests as a tourism resource has been sustainable. This book argues that sustainability must be the foundation on which tourism use of this complex but ultimately fragile ecosystem must be built upon. It provides a multi-disciplinary perspective, incorporating rainforest science, management and tourism issues. The book is organized into four sections commencing with Rainforest Ecology and Management followed by People and Rainforests, Opportunities for Rainforest Tourism Development and finally Threats to Rainforests. Each major rainforest region is covered, including the Amazon, Central America, Africa, Australia and south-east Asia, in the context of a specific issue. For example rainforests in Papua New Guinea are examined in the context of community-based ecotourism development, while the rainforests in Borneo are discussed in an examination of wildlife issues. Other issues covered in this manner include governance, empowerment issues for rainforest peoples and climate change.

Book Description
Extending from west Africa to Madagascar, from the vast lowland Congo Basin to the archipelago of forest islands on its eastern rim, the African rain forest is surpassed in size only by the Amazon. This book sheds light on the current efforts to understand and conserve the African rain forest, an area in need of urgent action to save its biological wealth, cultural heritage, and economic potential. Written by conservation scientists and practitioners based in the African rain forest, the book offers a multidisciplinary perspective that integrates many biological and social sciences. Early chapters trace the forces--from paleoecological factors to recent human actions--that have shaped the African forest environment. The next chapters discuss the dominant biological patterns of species ranging from the distinctive elephants, gorillas, and okapi to the less well known birds, butterflies, and amphibians. Other chapters focus on how such different groups as hunter-gatherers, forest farmers, bushmeat hunters, recent immigrants, and commercial foresters have used the forests. Several authors stress the need for tighter links between research and conservation action. The final section draws lessons from the collective experience of those working in an Africa wracked by political strife and economic hardship.
