Book Description
Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

Book Description
This final volume in the The Conservation Atlas of Tropical Forests covers the Americas. It provides an up-to-date overview of the status of rain forests in South America, Central America, and the Caribbean. Following the format of the two previous volumes The Conservation Atlas of Tropical Forests: Asia and the Pacific (1991) and The Conservation Atlas of Tropical Forests: Africa (1992), the atlas is divided into two parts. Part I introduces and discusses the complex interrelated issues in the regions that are involved in both deforestation as well as conservation of the tropical forests. Included are discussions on the history of the forests, agricultural colonization policies and deforestation, conservation polices for plants and wildlife, protected areas, and the future of the tropical forests. Part II is a detailed and well referenced country-by-country analysis of conservation status and trends. Four-colour maps have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies.

Book Description
"Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.

Book Description
Today, efforts are being made to rehabilitate badly degraded ecosystems and protect areas which have important ecological value, such as national parks, critical fish and wildlife habitats, natural communities and endangered species. Since human values are an integral part of the decisions to protect or rehabilitate-the goals and objectives for such actions are often unclear. Concepts of "health," "integrity" and "diversity" express important values associated with management actions but they do not provide clear guidelines for these actions. The criteria developed and applied in this book provide guidelines and serve as a road map to anyone involved in ecosystem management-scientists, land managers and policy makers.

Book Description
Small-scale fisheries make up a large proportion of world's fisheries, both by catch and participation. Effective management is essential to ensure access to fish for food and income. Covering social and economic aspects of the fishery management and governance challenge, this book provides guidance on innovative and alternative management measures and methods for small-scale fisheries. The book covers key topics such as rights, policy, co-management, communications and trade, and is an important reference for researchers and students in fisheries science and management as well as fisheries re.
