DOWNLOAD EBOOKCoastal lagoons and estuaries, lying at the boundary between ocean and land, house a unique mosaic of habitats, giving rise to high species diversity and the creation of ecotones. They are also ecologically and economically important ecosystems that provide many ecosystem services. Yet, these coastal ecosystems are facing a gamut of human-induced threats. This booklet is the fourth in the Coastal Ecosystems Series, published in an attempt to address the lack of information available to the general public regarding the threats to coastal ecosystems.

DOWNLOAD EBOOKWritten by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.

DOWNLOAD EBOOKManagement of artisanal fisheries in coastal lagoons and estuaries is treated in three broad categories -- regulatory management, non-regulatory management, and interactions between fisheries or fishery interests. Regulation of artisanal fisheries in coastal lagoons and estuaries by government authority is hampered for several reasons. Technical and financial constraints on government severely limit enforcement capabilities. Socio-economic considerations, chiefly the lack of alternative employment opportunities for fishermen, preclude the adoption of many of the classical regulatory management techniques. As a means to complement or supplement management by central government authority, revitalization of local traditional authority is advocated. Non-regulatory management, the application of methods which increase capture and culture fishery potential through manipulation of the environment, is illustrated by various kinds of hydraulic engineering, predator control, stocking, artificial nursery areas, and brush-park fisheries. Interactions between fisheries or fishery interests is treated at several levels. Considered are competition between groups of fishermen of different ethnic and economic backgrounds, interactions between artisanal capture fisheries and aquaculture, and competition between artisanal fisheries of coastal lagoons and estuaries and off-shore shore industrial fisheries which fish the same stocks.

DOWNLOAD EBOOKFive chapters are presented which address a number of aspects of riverine and runoff effects on coastal marine systems. Examples are presented and documented in which the apparent effects of runnoff-related nutrient enrichment and consequent eutrophication have been important. Various other aspects, such as sedimentation, etc. are explored. The purpose is to advance the scientific, policy, and political dialogue on issues related to utilization and protection of coastal marine ecosystems. The "Marine Catchment Basin" or "MCB" appears to be the logical scale of policy and management interest wherever terrestrial runoff has substantial impacts on a marine system. The MCB expands the "marine ecosystem" concept to include not only the marine aquatic system, but also the adjacent land areas that drain into it. The MCB concept has been identified primarily with semi-enclosed seas, where effects have been particularly dramatic and where the "catchment basin" retains an easily visualized geological context. However, even along open ocean coasts, hydrodynamic processes act to retain coherent masses of water, together with their contained organisms and materials, against the coast. Thus open coastal areas may exhibit MCB features similar to those of enclosed or semi-enclosed basins
