Unusually heavy rainfall, climate change, deforestation and two dams across the border in Brazil were cited by sources who spoke to IPS as the causes of the heaviest flooding in Bolivia's Amazon region since records have been kept.
Environmental organisations are discussing the possibility of filing an international legal complaint against the Jirau and Santo Antônio hydroelectric dams built by Brazil, which they blame for the disaster that has already cost 59 lives in Bolivia and material losses of 111 million dollars this year, according to the Fundación Milenio.
Bolivian President Evo Morales himself added his voice on Wednesday Apr. 2 to the choir of those who suspect that the two dams have had to do with the flooding in the Amazon region. "An in-depth investigation is needed to assess whether the Brazilian hydropower plants are playing a role in this," he said.
The president instructed the foreign ministry to lead the inquiry. "There is a preliminary report that has caused a great deal of concern…and must be verified in a joint effort by the two countries."
Some 30,000 families living in one-third of Bolivia's 327 municipalities have experienced unprecedented flooding in the country's Amazon valleys, lowlands and plains, and the attempt to identify who is responsible has become a diplomatic and political issue.
Environmentalists argue that among those responsible are the dams built in the Brazilian state of Rondônia on the Madeira river, the biggest tributary of the Amazon river, whose watershed is shared by Brazil, Bolivia and Peru.
