PHOTOS | Why Bolivia's dried up Lake Poopó may never recover

Environmental scientist Dirk Hoffmann says that rapid climate change, mining, and mismanagement of water have caused damage to Lake Poopó, that may be permanent.

Dusty, abandoned, fishing boats and the skeletal imprints of wildlife are all that remain on the parched bed of Bolivia's Lake Poopó. The reservoir was the second largest lake in Bolivia — but now, there's barely any water left.

As Andean glaciers disappear, so do the sources of Poopo's water. Glacial melting and the diversion of water from Poopo's tributaries are to blame, according to authorities.

The Bolivian government has declared the area a disaster zone and many scientists are concerned that Lake Poopó may never recover. Environmentalists charge that government and mining companies mismanaged water supplies, and that has accelerated the devastating effect of climate change.

"It's a huge area and that has now fallen completely dry," Dirk Hoffmann tells As It Happens host Carol Off.

"Seeing it completely dry, this is something completely new, we haven't seen that for the past decades," Hoffmann says. "People here are indeed shocked by what has happened."

People who have depended on the lake for income are being forced to find alternative livelihoods. Hoffmann says scientists are still trying to gauge the full damage to the ecosystem.

"What we know is that the lake itself held a lot of aquatic fauna and flora and that has completely died," Hoffman explains. "This is one of the main things worrying about recuperating the lake. Even if you brought back water to the lake, you wouldn't bring back flora and fauna to its original state, so this is really serious."

"With the winnings from fishing I have payed for my children's education and have been able to feed them well. Now we are very sad that the lake has dried up. I do not know what is going to happen to our children and grandchildren? How are they going to survive? But we have to come up with imaginative solutions." said Rojas. (Juan Karita/AP)

​Hoffmann admits the lake has dried up before but cautions not to confuse natural, cyclical climate variations with what's happening now. Increased mining and irrigation operations have depleted the river sources that feed the lake to unprecedented levels and along with global warming — the effect is likely irreversible.

"What people are still not getting very much is that climate change holds for a different future. It's not like the past being extrapolated into the future. Climate change will make things new." Hoffmann explains. "The combination of human interference and the ongoing global warming will make it very, very difficult to restore the ecosystem."
