Drought problems in our world
Drought problems and water shortages around our world today!
Today there are 30 cities with more than 10 million citizens, so called MEGA cities. Due 2010 almost every city stood under increased water shortages. UN had calculated that more than 1.8 billion people would suffer of water scarcity due the year 2025, but right now at least 2.7 billion people in 201 river basins faces water scarcity for at least one month each year, according to a new report published in journal PLoS ONE.
UN has also reported that by 2030, almost half of the world’s population will live in water-stressed areas.
The World Economic Forum calculates yearly investments of minimum 772 billion USD.
The American West and Southwest are headed for serious water shortages in the coming decades, US Interior Secretary Ken Salazar has told media. The 10 Western states that depend on the Colorado River and Rio Grande basins will see acute water shortages in the coming years due to the combination of reduced precipitation as a result of climate change and increased demand. Each spring, melted snow and ice from the Rocky Mountains recharge up to 80 percent of the Columbia, Missouri, and Colorado River Basins. Together, these basins form the primary water source for nearly 70 million people in an area plagued by droughts—including Denver, Las Vegas, Los Angeles, and Salt Lake City. More than 1 in 3 counties in the United States could face a “high” or “extreme” risk of water shortages due to climate change by the middle of the twenty-first century; 7 in 10 of the more than 3.100 U.S. counties could face “some” risk of shortages of fresh water for drinking, farming, and other uses. More than 1 in 3 counties in the United States could face a “high” or “extreme” risk of water shortages due to climate change by the middle of the twenty-first century, according to a new study in the American Chemical Society’s (ACS) journal. In USA and the last five years, nearly every region of the country has experienced water shortages. At least 36 states are anticipating local, regional, or statewide water shortages by 2013, even under non-drought conditions. Source: United States Environmental Protection Agency - EPA
In UK there are now up to 20 million households with water restrictions or bans. The Britons are not allowed to watering gardens, cleaning cars and more. Customers face 11.235 SEK/1.000 GBP/1.565 USD/88.000 INR fine if they are caught. For example; By the 2050s, between 27 million and 59 million people in the UK may be living in areas affected by water supply-demand deficits(based on existing population levels). Adaptation action will be needed to increase water efficiency across all sectors and decrease levels of water abstraction in the summer months. Source: UK Climate Change Risk Assessment 2012. In UK up to 20 million households are facing increased water usage; due the drought that researchers are say will be a normal activity in UK.
In France "All the warning lights are either orange or red," Miss Kosciuscko-Morizet said after chairing a high-level panel on drought. "The situation is similar to July in terms of water tables, river flow and snow runoff," she said. "We are now in a state of crisis." More than two-thirds of France's water tables are at below-normal levels, the Office of Geological and Mining Research(BRGM) said separately. Nearly a third of the country's 95 departments, or administrative districts, have imposed water restrictions on part or all of their territory. The worst-hit region is Poitou- Charentes, in the centre west, where restrictions have halved irrigation levels for farmland and outlawed lawn water and the filling of swimming pools.
Of Chinas 664 cities 60 % are suffering of water shortages. 21 % of Chinas water resources are unfit for use as potable water or irrigating. In China the pollution of the environment costs on yearly basis around 8-12 % of the China GDP. China will invest 610 billion USD to clean water resources and to cut down the emissions for the next 10 years. In May 2012 the Chinese Government for the first time spoke out to the public about their Hugh water problems; Underground water in 57% of monitoring sites across Chinese cities have been found to be polluted or extremely polluted, reports the state-run Economic Information Daily, citing figures from the Ministry of Environmental Protection. The ministry statistics also show that 298 million rural residents do not have access to safe drinking water. In the first half of last year, of the seven main water systems in China, only the Yangtze and Pearl rivers had good water quality, and the Haihe river in north China was heavily polluted, with the others all moderately polluted,according to the ministry.
Several countries are facing increased droughts combined with water scarcity such as Spain, Portugal, France, Italy, Greece, Czech Republic, Cyprus and Malta. All most every major city in Australia has restrictions or bans on potable water usage.
The water issue is no longer a poverty problem; it will affect financially strong countries such as England, France, USA, Australia and China among others.
