According to this article in the Guardian, “mega dams, agribusiness and climate change have all affected water supplies, say grassroots groups.”
Pablo Solon, Bolivia’s former ambassador to the UN in global climate change is quoted as saying “Cities are vulnerable to climate change but government policies are making climate change worse…. “There has been a huge development of extractive industries, like soya, mining and mega dams. There has also been a lot of deforestation. These have all worsened the water situation and made Bolivia, and other Latin American countries, more vulnerable to climate change.”
