Comments Off on One in four of world’s largest cities under water stress

Cape Town, South Africa is rapidly approaching what has been called “Day Zero,” the moment when the diverse metropolitan area of nearly 4 million runs out of clean drinking water . While Cape Town has taken drastic measures to conserve water , it is simply not enough to avoid the imminent crisis. And now, as government and residents prepare for the worst, it’s important to understand which other major cities around the world are also at risk. Lack of water is truly a global problem; one in four of the world’s largest cities are currently under “water stress,” with that number expected to rise due to climate change, human activity, and population growth. Water shortages have the potential to aggravate already unstable political and economic conditions, which is of particular concern in cities such as Cairo . Currently confronting violent extremism and managing ongoing political tension, Egypt is also rated by the World Health Organization as ranking high among middle-income countries on the number of deaths related to water pollution. This is tied to increasing pollution in the Nile River. The United Nations estimates that Egypt will suffer critical water shortages by 2025, exacerbating the potential for conflict. Similarly, São Paulo and Moscow are plagued by pollution due to poor public policy decisions. Fortunately, this means that the problem may be fixable, however entrenched it might be. Related: Venice’s canals go dry following weeks without rain Coastal cities like Jakarta and Miami are facing unique water problems as both attempt to pull freshwater from aquifers. Due to lack of public access to piped water, residents of Jakarta have dug illegal wells, draining the underlying aquifer and actually causing the land to sink. As a result, about 40 percent of Jakarta now lies below sea level. While Miami may not be sinking, its freshwater reserves are suffering from seawater contamination as a result of rapid sea level rise and wetland habitat destruction. Even cities like London are facing a water-scarce future, with severe shortages expected by 2040. Governments can make the necessary policy changes to solve this problem, but they must act quickly. The water crisis is already upon us in many cities. Via BBC News Images via Depositphotos (1) (2)

South Africa’s has declared a national disaster over the country’s devastating drought . Although Cape Town has pushed back day zero – the day that the city runs out of water – until June 4, the country re-assessed the magnitude of the drought and determined that it has reached disaster proportions.

Related: Cape Town’s water pipes could run dry by April Water consumption in South Africa has declined by about 139 million gallons per day thanks to residents who have worked hard to reduce usage. Residents are asked to use just 13 gallons of water a day. The hospitality industry has also gotten into the fight by asking hotel guests to keep showers under 2 minutes, and restaurants have stopped using linens and glassware to help reduce laundry needs.

There are also fears that the ongoing drought could harm the country’s industrial and agricultural output. Declaring the situation a national disaster allows the central government to take over relief efforts, which also means more money is available to address it.

Scientists Predict California May be Headed for a 100 Year Megadrought

Comments Off on Scientists Predict California May be Headed for a 100 Year Megadrought

Scientists predict that California’s current drought trouble may be just the beginning of a serious 100 year megadrought. Scientist Lynn Ingram has studied the history of drought in the western United States dating back 3,000 years, and the record indicates that California is now in one of its driest periods in over 400 years. With forecasters predicting the return of El Nino this year, it could spell disaster for the state, 95 percent of which is already experiencing drought.

Harvard Team to Convert Earth’s Unused Infrared Energy into Clean Electricity

Comments Off on Harvard Team to Convert Earth’s Unused Infrared Energy into Clean Electricity

Harvard Scientists are working on a new renewable energy system that can harvest the power of infrared energy from the Earth. Our own planet is constantly releasing hundreds of millions gigawatts of infrared radiation (which combines with our atmosphere to produce heat) into space and now physicists at the Harvard School of Engineering and Applied Sciences (SEAS) envision two devices to capture it all. The research team proposed a pair of devices akin to a photovoltaic power system . But instead of capturing incoming visible light, the device would generate direct current electrical power by emitting infrared light.
