Iraq's 'Pearl of the South' Lake Sawa Dry amid Water Crisis

Hussam al-Aqouli remembers the exact spot along southern Iraq’s Lake Sawa where his two daughters once dipped their feet into clear waters. Now he stands there two years on and the barren earth cracks beneath him.

This year, for the first time in its centuries-long history, the lake dried up. A combination of mismanagement by local investors, government neglect and climate change has ground down its azure shores to chunks of salt.

Lake Sawa is only the latest casualty in this broad country-wide struggle with water shortages that experts say is induced by climate change, including record low rainfall and back-to-back drought. The stress on water resources is driving up competition for the precious resource among businessmen, farmers and herders, with the poorest Iraqis counting among the worst hit amid the disaster.

“This lake was known as the pearl of the south,” said al-Aqouli, 35, a native of the nearby city of Samawa, looking out onto the dry cavernous emptiness. “Now it is our tragedy.”

Between the capital Baghdad and the oil-rich heartland of Basra, Muthanna is among Iraq’s poorest provinces. The number of those living under the poverty line in the province is almost three times the national average.

Desert expanses dominate the landscape with a narrow ribbon of farmland along the Euphrates River in the north. Economic development was hindered by the country’s turbulent history, neglect by the Baath party regime since the 1980s, then later by wars and sanctions.

Locals call the area surrounding Lake Sawa “atshan” — or simply “thirsty” in Arabic, The Associated Press reported.

Al-Aqouli spent his childhood frequenting the lake with his family. He hoped he could do the same when he started a family, he said. Instead he spends his days on social media writing long blog posts and urging Iraqis to take action. Often, he feels hopeless.

The lake rises 5 meters above sea level and is about 4.5 kilometers long and 1.8 kilometers wide.

Experts said the lake has not dried up for good but its disappearance this year is a concerning consequence of the thousands of illegal wells dug by businessmen in nearby cement factories and manufacturing zones, a result of drought and decreasing waters along the nearby Euphrates.

By early June, some water began to reappear because farmers, done with the harvest season, stopped diverting underground water.

Mounds of salt line the road to the river in Muthanna province and are overseen by enterprising locals who extract it by diverting groundwater and digging wells. The salt is used as a raw material in various industries in the area.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
