Floods Swamp Scores of Settlements in Russia and Kazakhstan

Floods gripped cities and towns across Russia and Kazakhstan on Wednesday after Europe's third-longest river burst its banks, forcing over 100,000 people to evacuate and swamping parts of the Russian city of Orenburg.

The deluge of melt water overwhelmed scores of settlements in Russia's Ural Mountains, Siberia, Volga and areas of Kazakhstan after major rivers such as the Ural, which flows into the Caspian, rose more 66 centimeters (2.17 ft) beyond its bursting point.

In Orenburg, a city with a population of 550,000 about 1,200 km (750 miles) east of Moscow, hundreds of homes were flooded and at least 7,700 people were evacuated as the Ural river rose swiftly beyond the critical level of 9.3 meters (30 feet).

"The water level in the Ural is rising," said Alexei Kudinov, the first deputy head of Orenburg. Reuters footage showed swathes of areas near the city under water.

Sirens and special television announcements ordered residents in the flood zones to evacuate, though some people decided to stay and were shown remaining in the attics of their houses.

The flood situation was acute in parts of Western Siberia, the largest hydrocarbon basin in the world, where the peak is expected in three to five days, and some areas around the Volga, Europe's largest river, the emergencies ministry said.

Residents in Orenburg said it was the worst flooding in living memory while Russian officials said it was the worst flooding in the area since record began. Kazakhstan said 96,000 people had been evacuated.

Russia said 10,500 houses were flooded across 37 regions, most in the Orenburg region. Upstream on the Ural, which flows into Kazakhstan, floodwaters burst through an embankment dam in the city of Orsk on Friday.

In Kazakhstan, people worked through the night to build up dykes and strengthen embankments.

Pope Francis expressed his sympathy for the victims of the floods.

"I also want to convey to the people of Kazakhstan my spiritual closeness at this time, when a massive flood has affected many regions of the country and caused the evacuation of thousands of people from their homes," Pope Francis said during his Wednesday weekly audience in St Peter's Square.

"I invite everyone to pray for all those who are suffering the effects of this natural disaster."

RECORD FLOODING

Spring flooding is a usual part of life across Russia as the harsh winter snows melt, swelling some of mighty rivers of Russia and Central Asia. This year, though, a combination of factors triggered unusually severe flooding.

Russian emergency officials said the soil was waterlogged before winter and then was frozen under very high snow falls which then melted very fast in swiftly rising spring temperatures and heavy rains.

One Russian official, the Presidential Plenipotentiary in the Urals Region, Vladimir Yakushev, was quoted by Russian media as suggesting that Kazakhstan was to blame for not coordinating the discharge of water more effectively.

President Vladimir Putin spoke to President Kassym-Jomart Tokayev of Kazakhstan about the floods on Tuesday. The Kremlin said the worst was still to come for the Siberian region of Tyumen and the Urals region of Kurgan.

The Kremlin said Putin was getting updated on the situation but had no immediate plans to visit the flood zone as local and emergency officials were doing their best to tackle the deluge.

Sirens in Kurgan, a city on the Tobol river, a tributary of the Irtysh, warned people to evacuate immediately.

Local authorities said they had closed several roads to traffic to quickly deliver soil to strengthen a dam there as water levels in the Tobol River quickly rose 23 centimeters (9 inches). The governor of the Kurgan region said 4,500 people had been evacuated from their homes in the province.

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.
