The area that will be flooded to build the HidroAysén project's five dams represents barely 0.05 percent of the Chilean region of Aysén. But it is made up precisely of the valleys where the majority of the population lives, according to local residents.
The effects of the HidroAysén dam project are already being felt in heightened tensions and severed social ties in Chilean Patagonia communities.
Environmental approval for the construction of five hydroelectric dams in Chile's southern Patagonia region has triggered nationwide protests in Chile, giving rise to a citizen's movement whose focus has gone beyond the question of the dams.
