FileHumboldt Current 64 Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:11 AM
The Humboldt Current region is located along western South America, stretching from the Ecuadorian-Colombian border (1° N) to the south of Chile (55° S). A feature of the continental area is the Andean Mountain range that extends along the entire region defi ning the catchment of the Humboldt Current region. The countries in the region include parts of Ecuador, Peru, Bolivia, Argentina and the whole of Chile. The impacts of the areas in Bolivia and Argentina on the Humboldt Current region are negligible and therefore these countries are excluded from the report.

FileIndian ocean Islands 45b Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:10 AM
The Indian Ocean Islands region comprises the island states of Comoros, Mauritius, Madagascar and Seychelles which are situated in the Western Indian Ocean (WIO). The combined total Exclusive Economic Zone (EEZ) of the Island States within the region is approximately 4.1 million km2. This provides the approximate limits of the region (between latitudes 5° N and 30° S and extending as far as 70° E). In terms of economic development, Mauritius and Seychelles appear to have met the basic conditions for sustainable human development, but considerable work is required in Madagascar and Comoros.

FileGuinea Current 42 Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:12 AM
GIWA region 42 covers the Guinea Current Large Marine Ecosystem (GCLME) and the basins of the rivers flowing into it. The coastal zone stretches over 5 560 km from the Bissagos archipelago in Guinea-Bissau to the mouth of the Congo River. The region includes 28 international river basins and covers entirely or partially 27 countries with a land area of 8 340 200 km2. In spite of the differences in size and population, the countries share many similarities in socio-economic conditions. First and foremost in relation to demography, culture and history; but also in relation to economy and social conditions, with the World Bank characterising most of the countries of the region as “Least developed countries”.
FileAmazon Basin 40b Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:11 AM
The Amazon Basin is the largest basin on the planet and also one of the least understood. Its drainage area covers more than one third of the South American continent, and its discharge contributes almost one fifth of the total discharge of all rivers of the world. The headwaters of the Amazon River are located about 100 km from the Pacific Ocean and it runs more than 6 000 km before draining into the Atlantic Ocean. In addition, the Amazon has 15 tributaries, including the Tocantins River, that measure more than 1 000 km in length.

FileEast China Sea 36 Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:10 AM
The critical stage of the aquatic environment has become widely more apparent not only for experts and scientist, but also for the general public. Freshwater depletion, pollution, habitat destruction and the unsustainable exploitation of living resources are serious transboundary problems that have developed over a fairly short timeframe. Global climate change will also result in unpredictable transformations that will alter the Earth’s freshwater and marine ecosystems.

This report presents the results of environmental and socio-economic assessment studies of the Yellow Sea (GIWA region 34a) and the associated water body, the Bohai Sea (GIWA region 34b). The studies, which were facilitated through workshops with the participation of international experts, included impact assessments and causal chain analyses to determine the impacts and root causes of the priority GIWA concerns and issues, respectively. Policy options and associated strategic action programmes were also identifi ed as to address the root causes of the priority environmental problem areas of the region based on the impact assessment and causal chain analysis results.

FileGulf of California, Calorado river basin 27 Giwa Regional Assessment by admin — last modified Jan 10, 2014 11:12 AM
The GIWA region 27 covers the Gulf of California and its drainage basins. This report focuses on the Colorado River Basin with emphasis on the delta area. The report presents the results of research, information development and policy analysis. The methodology covers issues such as water availability, regional imbalances, relationships between water use and water quality, and alternative low-cost natural systems for treating wastewater. The papers range from addressing fundamental scientifi c questions regarding the linkages between land use and water quality, to the ecological impacts of excessive water consumption, to the feasibility of applying alternative treatment options.
