Located in the southern region of America, the Rio da Prata Hydrographic Basin (or La Plata Basin and Basin Platinum, as it is also called) encompasses areas from five countries: Argentina, Bolivia, Brazil, Paraguay and Uruguay. With a total area of around 3,100,000 km², it is the second largest on the South American continent, just behind the Amazon Basin.
The Rio da Prata Basin is formed by the Paraná, Paraguay, Uruguay and Prata basins. The total population of the region, in 2015, was around 130 million inhabitants. It is of extreme economic importance for the countries it encompasses due to its hydroelectric potential, the largest in Brazil, and the irrigation of agricultural, livestock and mining activities.
In Brazil, the Rio da Prata Basin covers the states of Minas Gerais, Goiás, Mato Grosso, Mato Grosso do Sul, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul. In total, there are 1.428 million km².
In 1969, through the Silver Basin Treaty, signed that same year by the governments of Argentina, Bolivia, Brazil, Paraguay and Uruguay, the Intergovernmental Coordinating Committee of the La Plata Basin Countries was created (CIC). The agency is responsible for promoting, coordinating and following up on the region's development programs, as well as monitoring and controlling the environmental impact.
