Book Description
This report presents the results of the GIWA assessment of the Oyashio Current region - one of the most productive waters in East Asia. Changes in the hydrological cycle and ocean circulation have affected the productivity of the fisheries whilst overfishing has depleted commercial fish stocks. The past and present status and future prospects are assessed, and the prioritised issues traced back to their root causes. Policy recommendations are presented as contributions to broader policy processes in the region.--Publisher's description.

Book Description
Water circulates continuously and seamlessly on Earth with little regard for the boundaries we draw. There are natural boundaries as between land and ocean and surface and subsurface environments, as well as human or demographic boundaries between nations, cultures, and religions. Although considered necessary by societies, these human-created boundaries disrupt natural water circulation, leading to serious water-related environmental problems. The dilemma of how to manage water beyond our boundaries remains, and nations have different ways and means of controlling each form of water, whether as vapor, surface water, groundwater, or seawater. Recent findings on the interaction of water from land, oceans, and the atmosphere encourage researchers to undertake collaborative work that goes beyond the boundaries of each discipline, be it oceanography, surface and subsurface hydrology, climatology, or glaciology. Drawing on all these fields, the book focuses on two major boundaries: that between surface water and ground water, and that between terrestrial water and ocean water. This comprehensive work is of great value to experts in academia, international organizations, consulting firms, water resources, fisheries, and urban development planning agencies.

Book Description
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.

Book Description
The GIWA Final Report provides a comprehensive review of the most important findings from the GIWA regional reports. It summarises the major transboundary concerns and their environmental and socio-economic impacts. To better understand these concerns and develop solutions to address them, the Report identifies the root causes and draws policy relevant conclusions. It also outlines knowledge gaps which impede the sustainable management of international waters.

Book Description
This report presents the GIWA assessment of the Humboldt Current region, located along western South America, stretching from the Ecuadorian-Colombian border to the south of Chile. The world's largest upwelling area, supporting highly productive fisheries, is located within the boundaries of the region. The economy of the region is primarily based on fisheries, agriculture, oil-related industry, mining and maritime transport. As a result of the activities of these sectors pollution has come to constitute the major environmental and socio-economic concern in the region, followed by unsustainable exploitation of fish and other living resources. In the report the past and present status as well as future prospects of these concerns are discussed and subsequently traced back to their root causes. Policy options to mitigate these problems are proposed and aim to provide solutions to these fundamental issues in order to enhance the management of the regions aquatic environment.--Publisher's description.
