Climate change and water mismanagement parch Egypt

Climate change and water mismanagement parch Egypt | oAnth's day by day interests - via its scoop.it contacts | Scoop.it

Climate change, a fast growing population, ill-designed infrastructure, high levels of pollution and lack of law enforcement have made Egypt a country thirsty for water — both in terms of quantity and quality.

The River Nile, which is considered poor by many experts and hydrologists, lies at lower altitude than the rest of the country. Massive electric pumps extract the water from the river’s bed and canals and direct it to industry, agriculture and for individual water use.

A significant portion of the water contained in Lake Nasser’s 5,000 square kilometer basin is lost to evaporation, while old networks of leaking pipes also deprive the country of satisfactory access to its most important resource: water.

In order to debate water scarcity in Egypt, its causes, and how climate change makes the issue more pressing than ever, as well as looking to solutions, a panel of experts were invited to participate in the 13th Cairo Climate Talk last week entitled “Growing Thirst: Sustainable Water Solutions for Egypt.”

Tarek Kotb, the First Assistant Minister in the Ministry of Water Resources and Irrigation, and a member of the panel discussion, talked about the dwindling water share per capita with a sense of urgency. “Every year, the Egyptian population grows by 1.8 million, while the annual quota of Nile water allocated to Egypt, 55 billion cubic meters, has remained unchanged since the 1959 Nile Water Agreement,” he says.

While Egyptians in the 1960s could enjoy a water share per capita of 2800 cubic meters for all purposes, the current share has dropped to 660 cubic meters today—below the international standard defining water poverty of 1000 cubic meters.

Kotb estimates that Egypt is gradually going to leave the stage of water scarcity and enter a phase of drastic water stress in the next 40 years, if no sustainable water management is put in place.

“By 2050, there will be about 160 million Egyptians and only 370 cubic meters of water per capita,” he says. While Egypt has other options for its water needs, such as tapping into groundwater basins and desalinating sea-water, the bulk of water is still extracted from the Nile, leading to longstanding tensions with the other Nile basin countries.

Fracking and Shale Oil Won’t Lead to U.S. Energy Independence

Fracking and Shale Oil Won’t Lead to U.S. Energy Independence | oAnth's day by day interests - via its scoop.it contacts | Scoop.it

The United States could see a surge in oil production that could make it the world’s leading oil producer within a decade, according to a new report from the International Energy Agency. But that lead will likely be temporary, and it still won’t allow the United States to stop importing oil. Barring technological breakthroughs in oil production and major reductions in consumption, the United States will need to rely on oil from outside its borders for the foreseeable future.


This week’s IEA report predicts that a relatively new technology for extracting oil from shale rock could make the United States the world’s leading oil producer within a decade, beating the current leader, Saudi Arabia. The idea that the U.S. could overtake Saudi Arabia, even temporarily, is a stunning development after years of seemingly inexorable declines in domestic oil production. U.S. production had fallen from 10 million barrels a day in the 1980s to 6.9 barrels per day in 2008, even as consumption increased from 15.7 million barrels per day in 1985 to 19.5 million barrels per day in 2008. The IEA estimates that production could reach 11.1 million barrels per day by 2020, almost entirely because of increases in the production of shale oil, which is extracted using the same horizontal drilling and fracking techniques that have flooded the U.S. with cheap natural gas.


As of the end of 2011, production had already increased to 8.1 million barrels per day, almost entirely because of shale oil. Production from two major shale resources in the U.S.—the Bakken formation in North Dakota and Montana and the Eagle Ford shale in Texas, now total about 900,000 barrels per day. In comparison, Saudi Arabia is expected to produce 10.6 million barrels per day in 2020.The shale oil resource, however, is limited. The IEA expects production to start gradually declining by the mid-2020s, at which time Saudi Arabia will reclaim the top spot.


Shale oil is creating a surge in U.S. oil production in part because it’s easy to find, says David Houseknecht, a scientist at the U.S. Geological Survey. The oil is spread over large areas, compared to the relatively small pockets of more conventional oil deposits in the United States. So whereas wildcatters drilling for conventional oil might come up empty two-thirds of the time or more, over 95 percent of shale oil wells strike oil.


Just how much shale oil can be produced—and how fast—depends heavily on two factors: the price of oil, and how easy it is to overcome possible local objections to oil fracking, says Richard Sears, a former executive at Royal Dutch Shell and a visiting scientist at MIT. Oil shale costs significantly more to produce than oil in Saudi Arabia and many other parts of the world, so for oil companies to go after this resource, oil prices need to stay relatively high. It’s hard to put a firm number on it, but Sears estimates that $50 to $60 a barrel would be enough, compared to the $85 per barrel price of oil now. Houseknecht puts the cost of production at closer to $70 a barrel. Although costs for producing conventional oil in the Middle East also vary, they typically don’t change more than $10 per barrel.

I really think the U.S. should stop importing so much oil from the middle-east because you never know when they could possibly cut us off due to political differences or something. At least if we were to produce some and import some they'd make the price at the pump go lower for us. Which would boost the economy. But I think that if we are to become a leading producer of oil in the world, I think we should make ourselfs independant in ways of producing energy for ourselves. I think it would just lead to less problems and make it easier for everybody.
