This report is based on a review of literature and experience relating to the planning and management of aquaculture development and its integration into coastal area management. It explores in detail how more planned and integrated approaches can be applied to aquaculture development. These approaches range from "enhanced sectorial" initiatives, to incorporation within comprehensive ICM programmes.
Coastal Marine Ecosystems of Latin America

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

This book uses five decades of map data, air photos, and medium to high-resolution satellite imagery to track the expansions of aquaculture and the loss of both estuarine and mangrove land covers in Ecuador. The results are staggering. In some regions, Ecuador has lost almost 50% of its estuarine space and approximately 80% of its mangrove forest. The current estuarine land cover bears no resemblance to the historic estuarine land cover. The analysis is complete from 1968 to 2014. The analysis covers all the major estuaries of mainland Ecuador. The research expands beyond purely land cover into the land use of the estuaries and the implications of the land cover transitions. The author lived in Ecuador's estuarine environments for almost two years studying this area. During this time he conducted mapping workshops with local residents, conducted 100 interviews with local actors, conducted six group discussions with fisherfolk syndicates, conducted eight presentations, worked on a shrimp farm. He was employed by the Ministry of the Environment on a Prometeo fellowship for one-year researching estuarine health and worked on mangrove replanting projects in the estuaries. In addition to the remote sensing data, the author provides a contextual framework to the analysis. It is not just hard numbers that are presented, but a remote sensing analysis tied to local actors that tell a coherent almost 50 -year estuarine story at the national, provincial, and local scales The book is intended for researchers, academics, graduate students, NGOs, and government actors including those who work in development, environment, and policy implementation. It is suitable supplemental reading for students in courses related to the coastal zone, land use change, and remote sensing. The electronically supplementary material includes all the related data to underpin the analysis as well as all the resulting GIS files.

Proceedings of a Conference on Sustainability of Wetlands and Water Resources

| ISBN | : |
The conference focused on recent work in freshwater wetlands [both natural and constructed] with a view toward understanding wetland processes in a watershed context. Since humans have played important roles in watershed dynamics for years, attention was given to the human dimensions of wetland and watershed uses. Contributed sessions were organized on: biogeochemical cycling in wetlands; human health issues related to water; wetland restoration and reforestation; the role of wetlands in agricultural systems; wetlands and USA environmental law; chemical ecology and natural products from wetlands; water and wetlands in science education; and regional water strategies.

Bill Streever, author of Bringing Back the Wetlands and numerous technical articles about wetland restoration and creation, worked for two years to bring together this collection of papers. Authors ranging from private landowners to government managers to scientists present regional overviews, case studies, and discussions of various issues. Regional overviews cover areas as small as the Commonwealth of the Northern Mariana Islands to areas as large as Australia and Africa. Case studies range from relatively small projects, such as rehabilitation of damage caused by wheel ruts in the high arctic, to much larger projects, such as attempts to rehabilitate thousands of hectares of Northern Territory wetlands in Australia. Seedbank ecology, economics, remote sensing, community involvement, the role of the wetland consulting industry, and other issues are discussed. In an effort to synthesize information from around the world, Joy Zedler presents a model that allows comparison of projects and may lead to better predictability of project outcomes. In An International Perspective on Wetland Rehabilitation, authors describe planting, engineered structures, prescribed flooding, excavation, and other rehabilitation methods, from Israel to New Zealand to the Netherlands and elsewhere. For the first time, one volume offers an impression of the magnitude and diversity of the field of wetland rehabilitation around the globe.

This book focuses on the challenges people face in managing agricultural crops, aquaculture, fisheries and related ecosystems in areas of coastal zones in the tropics of Asia, Africa, Australia and South America. Challenges arise from conflicts in the use of natural resources among different stakeholders. Through many case studies, the book discusses the nature of these conflicts and identifies what is known and not known about how to manage them. Case studies include: · trade-offs between enhancing agricultural production and maintenance of rural livelihoods and aquatic biodiversity.· lessons learnt from the conversion of mangrove forests to shrimp farms.
