Water Resources Management In Argentina
Water resources management (WRM) functions in Argentina are handled by multiple institutions operating at the national, provincial, and river basin level, with a variety of functions and jurisdictions. On the national level, the ''National Institute for Water and the Environment (INA)'' and the ''National Water and Sanitation Utility (AySA)'' are charged with the duties of researching, water resources preservation, developing services, and implementing water projects. Connectivity to water in urban settings is quite good in Argentina, but rural communities lag far behind that of less developed nations. This problem is made worse by one of the highest levels of per capita usage in the world at around 500 L/day. Large rivers and aquifers represent the main source of drinking water supplies and they are facing serious water pollution problems from industrial effluents, urbanization, and harmful agriculture practices. Many other challenges persist throughout the country and most are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Río Negro (Argentina)
Río Negro (; ''Black River'') is the main river of Patagonia in terms of the size of its drainage basin, its associated agricultural produce and population living at its shores. In eastern Patagonia it is also the largest by flow rate. The river flows through the Argentine province of Río Negro which is named after it. Its name comes from the literal translation of the Mapuche term ''Curu Leuvu'', although the water is more green than black. Formerly, it was also known as "river of the willows" because of the big number of weeping willows that grow along the bank. It is 635 km in length. It originates from the junction of the Limay River and Neuquén River at the border with the Neuquén Province, and flows southeast incised through steppes to the Atlantic Ocean at , near El Cóndor beach resort some downstream from Viedma, Río Negro province's capital. The river allows the Río Negro province to produce 70% of the pears and 72% the apples of Argentina. The main area o ...

Patagonia
Patagonia () refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.Manuel Enrique Schilling; Richard WalterCarlson; AndrésTassara; Rommulo Vieira Conceição; Gustavo Walter Bertotto; ...

Dry Pampas
The Semi-arid Pampas, also known as the Dry Pampas, is a temperate grassland ecoregion of central Argentina. Setting The Semi-arid Pampas cover an area of , including western Buenos Aires Province, southern Cordoba and San Luis Provinces and most of La Pampa Province. The area is, in all, home to no more than a million people, who generally enjoy some of the nation's lowest poverty rates. The Humid Pampas grassland lies to the east, while the drier Argentine Espinál (thorny) grassland lies to the west. The soil tends to be sandier in this region than to the east, though both regions are characterized by their mostly minimal incline and frequent finger lakes. Generally more similar than not, these two biomes are mostly distinguished by their contrasting rainfall quantities, soil quality and land use; this section of the pampas typically sees about a third less rainfall (700 mm, 27 in) than the humid pampas. Flora Not unlike the more humid pampas to the east, thi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Endorheic Basin
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'wit ...

Futaleufú River
The Futaleufú River, located in northern Patagonia, is one of the premier whitewater rivers in the world. One of only two rivers to cross the 5,308 kilometer Chile-Argentina border, the Futaleufú headwaters can be found in the glacial snow melt of the UNESCO protected Los Alerces National Park in Argentina. The river gorge drops as low as below the surrounding glaciated peaks. The name Futaleufú is an indigenous Mapuche word meaning "Big River.” Locals refer to the valley as "un paisaje pintado por Dios"—a landscape painted by God. Geography The Futaleufú River is fed by a chain of lakes in the Los Alerces National Park in Chubut Province, Argentina. The name, Futaleufú, is given to the river below the Futaleufú Dam and Amutui Quimey Reservoir. The watershed drains the Southern Andes Mountains from Argentina into Chile and drains into Yelcho Lake. From this point the river is renamed Rio Yelcho and continues to its mouth at the Pacific Ocean. From its source in Argen ...

Uruguay River
The Uruguay River ( es, Río Uruguay, ; pt, Rio Uruguai, ) is a major river in South America. It flows from north to south and forms parts of the boundaries of Brazil, Argentina, and Uruguay, separating some of the Argentine provinces of La Mesopotamia from the other two countries. It passes between the states of Santa Catarina and Rio Grande do Sul in Brazil; forms the eastern border of the provinces of Misiones, Corrientes, and Entre Ríos in Argentina; and makes up the western borders of the departments of Artigas, Salto, Paysandú, Río Negro, Soriano, and Colonia in Uruguay. Course The river measures about in length and starts in the Serra do Mar in Brazil, where the Canoas River and the Pelotas River are joined, at about above mean sea level. In this stage the river goes through uneven, broken terrain, forming rapids and falls. Its course through Rio Grande do Sul is not navigable An unusual feature of the Uruguay River is a submerged canyon. This canyon fo ...

Water Scarcity
Water scarcity (closely related to water stress or water crisis) is the lack of fresh water Water resources, resources to meet the standard water demand. There are two types of water scarcity: physical or economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function effectively. Desert climate, Arid areas for example Central and West Asia, and North Africa often suffer from physical water scarcity. On the other hand, economic water scarcity is caused by a lack of investment in infrastructure or technology to draw water from rivers, aquifers, or other water sources, or insufficient human capacity to satisfy the demand for water. Much of Sub-Saharan Africa has economic water scarcity. The essence of global water scarcity is the geographic and temporal mismatch between fresh water demand and availability. At the global level and on an annual basis, enough freshwater is available to meet such ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
