Book Description
The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.

Book Description
Africa's forests are being depleted at a faster rate than of any other continent. A major increase in the population growth rate began after World War II and it is now running at an annual rate of 2.9 per cent, resulting in massive demands for agricultural land, water, fuelwood and other products. There is no simple answer to environmental degradation and forest conservation must be part of a broader process of managing the landscape. Here to address this topic is the new Conservation Atlas of Tropical Forests: Africa, the first authoritative reference work on this subject. The second in a series this Conservation Atlas follows the format of the acclaimed Conservation Atlas of Tropical Forests: Asia and the Pacific (1991). Part I describes the issues, history of forests and climate, biological diversity, conservation of large mammals, and the peoples of the forests. Included are discussions of the links between population, environment and agriculture, the timber trade, protected areas system and the future for Africa's forests. Part II of the Atlas is a country by country survey of the forests of Africa. Stunning four-color maps, in a 9 x 12 format, have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies. Both maps and text have been prepared and reviewed by a broad spectrum of specialists. The Atlas also includes four-color photographs and sketch maps. They represent the best visual portfolio available of Africa's forests today. For anyone interested in environmental issues, geography, forestry, development, economics, and the African region, this Atlas will be an essential resource.

Book Description
Southeast Asia constitutes one of the world's most extended rainforest regions. It is characterized by a high degree of biodiversity and contains a large variety of endemic species. Moreover, these forests provide a number of important and sin gular ecosystem services, like erosion protection and provision of high quality wa ter, which cannot be replaced by alternative ecosystems. However, various forms of encroachment, mostly those made by human interventions, seriously threaten the continuance of rainforests in this area. There is ample evidence that the rainforest resources, apart from large scale commercial logging, are exposed to danger particularly from its margin areas. These areas, which are characterized by intensive man-nature interaction, have been identified as extremely fragile systems. The dynamic equilibrium that bal ances human needs and interventions on the one hand, and natural regeneration capacity on the other, is at stake. The decrease of rainforest resources is, to a sub stantial degree, connected with the destabilization of these systems. Accordingly, the search for measures and processes, which prevent destabilization and promote stability is regarded as imperative. This refers to both the human and the natural part of the forest margin ecosystem.
