As a species we expanded on the margins of large rivers; we took from them the water we drink, cook, bathe and manufacture several products. Part of our electricity comes from their water power; but our relationship with rivers became predatory, lethal in most of the times. Will we be able to improve it someday?
A recent study by researchers in the Americas, Europe and Australia shows that deforestation and large use of soil for cattle pastures and crops have increased the flows of sediments in many rivers. Road construction has caused erosion of surfaces and landslides in different regions of the planet.
The video, produced with images taken by NASA's Terra satellite, shows the progression of deforestation in Rondônia state (Brazil) between 1975 and 2012.
These dams also cause losses to populations and drastic changes in ecosystems where they are installed; therefore many activists and researchers question governments around the world on how clean would be the energy produced by hydroelectric plants.
In Brazil, the Belo Monte plant is object of wide political and environmental controversy; the plant is being built in the Xingu River around Altamira, north of Pará, where more than 500 families were displaced to vacate the land for the dam construction.
The project that provides for the construction of five plants in Tapajós River – Tapajós Complex in the State of Pará – has also generated a lot of stress between the Munduruku people and the Brazilian Government. In August 2016, the IBAMA – Brazilian Institute of Environment and Renewable Natural Resources – shelved the granting of environmental licensing of the Complex; besides being environmentally unfeasible, the works would flood an entire Munduruku village – which is prohibited by the Brazilian Constitution that allows the removal of indigenous peoples from their lands only in case of natural disasters or epidemics.
