Sea turtles are flagship species for the world's oceans. They traverse international boundaries during their migrations, serve as vehicles for marine nutrients to terrestrial habitats, and embody the often tenuous relationship between human action and ecosystem health. The East Pacific Ocean is home to some of the most dynamic marine ecosystems, and the most unique sea turtles. Marine biodiversity within this massive ocean region abounds in mangrove estuaries, seagrass pastures, coral reefs, the open ocean, and many other habitats, with sea turtles often the most conspicuous species present. The distinctive traits of the Eastern Pacific have resulted in the smallest leatherbacks, a singular morph of the green turtle, dark and steeply domed olive ridleys, and the most cryptic hawksbills on the planet. Only now are we beginning to understand how these varieties have evolved. However, the oceanographic conditions that make this an epicenter of sea turtle activity also promote massive artisanal and industrial fishing efforts that, coupled with illegal harvesting of eggs and turtles, have led to declines of several turtle populations in the region. The essays and stories in Sea Turtles of the Eastern Pacific describe for the first time the history of this exploitation, as well as recent sea turtle conservation initiatives and scientific research in the region. The first third of the book considers the biology of the turtles, focusing on general overviews of current ecological management challenges facing the turtles' survival. The second third treats issues of marine policy related to turtle conservation. In conclusion, the book offers six compelling stories of conservation success. By the end, readers will have gained a in-depth view not only of these magnificent creatures, but also the people involved in research and conservation efforts in one of the most remarkable regions of our planet.

This report presents the assessment of the GIWA Eastern Equatorial Pacific region, which includes parts of Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama and Colombia. Pollution in the Southwest Mexico sub-system, freshwater shortage in the Central Equatorial Pacific sub-system, and the unsustainable exploitation of fish and other living resources in the Pacific Colombian sub-system were considered as the priority concerns. The root causes of these water-related problems are identified and policy options are proposed.--Publisher's description.

Despite the central role oceans play in the economic, environmental and social affairs of the planet's 6.7 billion inhabitants, significant gaps exist in our understanding and management of the complex processes at work from the global climate system, to the water cycle and circulation of nutrients, to changes affecting marine habitats. In addition, the vastness of the world's oceans have for far too long been perceived as impervious and indestructible to human impact. To deal with this situation, improved monitoring and observation practices, regular assessments to provide a deeper understanding of the status and trends of environmental changes, and the know-how and ability to prevent, mitigate and adapt to these changes are urgently required. The UN General Assembly in 2005 -- recommended that a regular process for the global reporting and assessment of the state of the marine environment, including its socio-economic aspects (Regular Process), be initiated. The UN Environment Programme (UNEP) and the Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) were asked to serve as the lead agencies in the start-up phase that came to be known as the "Assessment of Assessments" (AoA). Under the AoA, an Expert Group have developed options and a framework for such a Regular Process, which can serve as the mechanism to keep the world's oceans and seas under continuing review.

The "Assessment of Assessments" (AoA) is a start-up phase of a regular process for global reporting and assessment of the state of the marine environment including socio-economic aspects. AoA represents the most comprehensive initiative undertaken to date by the UN system to better coordinate ocean governance. Its central recommendation calls for a mechanism that builds on existing global, regional and national institutions and processes while integrating all available information, including socio-economic data, on how our seas and oceans are actually being used.--Publisher's description.
