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.

The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Niño, and La Niña. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins ́ Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.

This book reviews the frameworks and implementation of marine, fishery and coastal laws and policies in Chile, Mexico and Peru. Chile, Mexico and Peru share biodiverse coastal and marine environments which are being affected by unregulated and informal developments, and thus share similar challenges. Each country is currently at a different stage of advancement in their institutional response to these complex challenges. By providing a comparison of the frameworks, approaches and overall implementation of policies and laws, this book acts as a tool to influence and inform further efforts in conservation and sustainable use of marine resources, particularly fisheries, in these countries and others in Latin America and the Caribbean. A broad range of issues are covered including food security, tourism, fisheries, oil and mineral extraction from the seabed, wind power, coastal and marine pollution and endangered species conservation. The chapters compare how each country addresses these issues from an institutional, legal and policy perspective. The book concludes by identifying common lessons, reoccurring challenges and develops scalable recommendations applicable to the case study countries and the wider region. The book will be of interest to advanced students, policy makers and researchers in marine and fishery science, law and policy.

Latin America and the Caribbean (LAC) region is exceptionally biodiverse. It contains about half of the world’s remaining tropical forests, nearly one-fifth of its coastal habitats, and some of its most productive agricultural and marine areas. But agriculture, fishing and other human activities linked to rapid population and economic growth increasingly threaten that biodiversity. Moreover, poverty, weak regulatory capacity, and limited political will hamper conservation. Given this dilemma, it is critically important to design conservation strategies on the basis of the best available information about both biodiversity and the track records of the various policies that have been used to protect it. This rigorously researched book has three key aims. It describes the status of biodiversity in LAC, the main threats to this biodiversity, and the drivers of these threats. It identifies the main policies being used to conserve biodiversity and assesses their effectiveness and potential for further implementation. It proposes five specific lines of practical action for conserving LAC biodiversity, based on: green agriculture; strengthening terrestrial protected areas and co-management; improving environmental governance; strengthening coastal and marine resource management; and improving biodiversity data and policy evaluation.
