The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contributors include more than fifty expert scientists. They summarize the current state of knowledge on the taxonomy, species richness, and ecology of these fish groups, and provide references to relevant literature for species-level identifications. This richly illustrated guide contains 700 detailed drawings, 190 color photos, and 500 distribution maps, which cover all genera. An extensive and illustrated glossary helps readers with the identification keys. The first complete overview of the fish diversity in the Amazon, Orinoco, and Guianas, this comprehensive guide is essential for anyone interested in the freshwater life inhabiting this part of the world. First complete overview of the fish diversity in the Amazon and Orinoco basins Contributors include more than fifty experts Identification keys and distribution maps for all genera 190 stunning color photos 700 detailed line drawings Extensive and illustrated glossary

For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of integrated planning of storage in both basins. Recommendations are made for improved planning in the future.
