ASTANA. KAZINFORM – Overturned fishing skiffs lie abandoned on the shores of what was Bolivia’s second-largest lake. Beetles dine on bird carcasses and gulls fight for scraps under a glaring sun in what marshes remain.<\/p>\n
Lake Poop\u00f3 was officially declared evaporated in December. Hundreds, if not thousands, of people have lost their livelihoods and gone.<\/p>\n
High on Bolivia’s semi-arid Andean plains at 3,700 metres (more than 12,000 feet) and long subject to climatic whims, the shallow saline lake has essentially dried up before only to rebound to twice the area of Los Angeles.<\/p>\n
But recovery may no longer be possible, scientists say.<\/p>\n
“This is a picture of the future of\u00a0climate change,” says Dirk Hoffman, a German glaciologist who studies how rising temperatures from the burning of fossil fuels has accelerated glacial melting in Bolivia.<\/p>\n
As Andean glaciers disappear, so do the sources of Poop\u00f3’s water. But other factors are in play in the demise of Bolivia’s second-largest body of water behind Lake Titicaca.<\/p>\n
Drought caused by the recurrent\u00a0El Ni\u00f1o meteorological phenomenon\u00a0is considered the main driver. Authorities say another factor is the diversion of water from Poopo’s tributaries, mostly for mining but also for agriculture.<\/p>\n
More than 100 families have sold their sheep, llamas and alpaca, set aside their fishing nets and quit the former lakeside village of Untavi over the past three years, draining it of well over half its population. Only the elderly remain.<\/p>\n
“There’s no future here,” says 29-year-old Juvenal Gutierrez, who moved to a nearby town where he has taken a job as a motorcycle taxi driver.<\/p>\n
Record-keeping on the lake’s history goes back only a century, and there is no good tally of the people displaced by its disappearance. At least 3,250 people have received humanitarian aid, the governor’s office says.<\/p>\n
Poopo is now down to 2% of its former water level, regional governor Victor Hugo Vasquez calculates. Its maximum depth once reached five metres (16ft). Field biologists say 75 species of birds are gone from the lake.<\/p>\n
While Poop\u00f3 has suffered El Ni\u00f1o-fuelled droughts for millennia, its fragile ecosystem has experienced unprecedented stress in the past three decades. Temperatures have risen by about 1 degree Celsius while mining activity has pinched the flow of tributaries, increasing sediment.<\/p>\n
Florida Institute of Technology biologist Mark B. Bush says the long-term trend of warming and drying threatens the entire Andean highlands.<\/p>\n
A 2010 study he co-wrote for the journal Global Change Biology said Bolivia’s capital, La Paz, could face catastrophic drought this century. It predicted “inhospitable arid climates” would lessen available food and water this century for the more than 3 million inhabitants of Bolivia’s highlands.<\/p>\n
A study by the German consortium Gitec-Cobodes determined that Poop\u00f3 received 161bn fewer litres of water in 2013 than required to maintain equilibrium.<\/p>\n
“Irreversible changes in ecosystems could occur, causing massive emigration and greater conflicts,” said the study commissioned by Bolivia’s government.<\/p>\n
The head of a local citizens’ group that tried to save Poop\u00f3, Angel Flores, says authorities ignored warnings. “Something could have been done to prevent the disaster.\u00a0Mining\u00a0companies have been diverting water since 1982,” he says.<\/p>\n
President Evo Morales has sought to deflect criticism he bears some responsibility, suggesting Poop\u00f3 could come back.<\/p>\n
“My father told me about crossing the lake on a bicycle once when it dried up,” he said in December after returning from the UN-sponsored climate conference in Paris.<\/p>\n
Environmentalists and local activists say the government mismanaged fragile water resources and ignored rampant pollution from mining, Bolivia’s second export earner after natural gas. More than 100 mines are upstream and Huanuni, Bolivia’s biggest state-owned tin mine, was among those dumping untreated tailings into Poop\u00f3’s tributaries.<\/p>\n
After thousands of fish died in late 2014, the Universidad Tecnica in the nearby state capital of Oruro found Poop\u00f3 had unsafe levels of heavy metals, including cadmium and lead.<\/p>\n
The president of Bolivia’s National Chamber of Mining, Saturnino Ramos, said any blame by the industry was “insignificant compared to climate change.” He said most of the sediment shallowing Poopo’s tributaries was natural, not from mining.<\/p>\n
In hopes of bringing it back, Morales’ government has asked the European Union for $140m for water treatment plants for the Poop\u00f3 watershed and to dredge tributaries led by the Desaguadero, which flows from Lake Titicaca.<\/p>\n
But critics say it may be too late.<\/p>\n
“I don’t think we’ll be seeing the azure mirror of Poop\u00f3 again,” said Milton Perez, a Universidad Tecnica researcher. “I think we’ve lost it.”<\/p>\n
