"The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons' ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons' environment."--Publisher's description.
Deforestation, soil erosion, desertification, air and water pollution, loss of wildlife habitat, and declining biodiversity are interrelated manifestations of a growing environmental crisis in North Africa that has received relatively little attention from government policymakers and is poorly understood by North African peoples, the international development community, and scholars. In this book a multidisciplinary group of scholars explores the broad range of human activities causing the deterioration of North Africa’s fragile environment, including population pressure and poverty, rapid urbanization, intense competition for land and water, and mismanagement of natural resources. The contributors examine in particular the conflict between economic development and environmental sustainability. They analyze the historical roots of current environmental problems, the underlying socioeconomic causes, potential solutions, and differences in environmental policies among various countries. This is an insightful portrait of a developing region attempting to reconcile traditional methods of land use with growing demands for resources, the exigencies of economic development, and the limitations of its natural resource base.

A derivative of the Encyclopedia of Inland Waters, Lake Ecosystem Ecology examines the workings of the lake and reservoir ecosystems of our planet. Information and perspectives crucial to the understanding and management of current environmental problems are covered, such as eutrophication, acid rain and climate change. Because the articles are drawn from an encyclopedia, the articles are easily accessible to interested members of the public, such as conservationists and environmental decision makers. - Includes an up-to-date summary of global aquatic ecosystems and issues - Covers current environmental problems and management solutions - Features full-color figures and tables to support the text and aid in understanding
