Create a Water Scarcity Climate Change

German scientists calculate how much water reserves are disappearing due to climate change. Agriculture is a sector that is being targeted for water savings.
It's no secret if water resources are shrinking every year . Population growth and the increasing need for food and water was the cause . Climate change also contributed to evaporate the water source .
Scientists at Potsdamer Instut for Climate Change Impact Research reveal how much water is disappearing due to climate change impacts . The researchers used data from five climate simulations and eleven global hydrological simulations to measure the impact of global warming more accurately .
Target of research is to find new methods to prevent water scarcity . " In the future scenarios we need to know how big the role of climate change , " said Jacob Schewe , one of the researchers .

Climate change could be Terminated
The important thing is to know the impact of climate change on the world's water reserves . Because scientists believe humans are still able to stop global warming .
" From the point of natural science , climate change could still be stopped , " said Schewe . "If we run the program a massive climate protection in the next few decades , the rate of warming can be limited in the range of 1.5 degrees Celsius and we were able to prevent the occurrence of water scarcity . "
Recent studies have shown a rise in temperature of the earth by 2.7 degrees Celsius compared to the period before the era of industrialization . Make the Earth's population , the figure is one-tenth of people will suffer from a shortage of drinking water at the end of this century .
Scientists define water scarcity as the level of consumption of 500 cubic meters of water per year for each person . Currently water demand is expected to average 1200 cubic meters per year . The rate of water consumption per person in the industrialized countries is clearly much higher than the population in developing countries .

famineTo prevent water scarcity , scientists urged the agricultural and livestock sectors are looking for new methods . Moreover, farmers will face more frequent droughts or rain and storms bubbling river . The threat to double the risk of famine in poor countries .
Create a German agricultural expert , Rudolf Herren , adaptation in the agricultural sector can not be realized only by relying on technology investments . " The technical solution to conserve water in the agricultural sector will only play a minor role in the next 50 years . Cost is too high , " he said .
The agriculture sector will face two impacts of climate change in the future , said Herren : Drought and floods . According to the two disasters can only be overcome with biological farming systems , " so we can enlarge the capacity of the soil to hold water and to enrich its content and use at the plant . "

adaptation culinary
Ecological agriculture in addition can block the spread of disease and pests without the use of pesticide substances . Pest is believed to be difficult to settle if farmers rotate and enrich the diversity of plants on their land . Monoculture , according to Herren , it serves as a freeway for pests and diseases .
However the efforts of farmers , consumers also have to get used to the different types of food . One is to reduce meat consumption . Besides plants should also be adapted to the geographical conditions .
Corn requires large amounts of water , for example can not be grown in dry areas . Instead of farmers in the region can cultivate millet water very sparingly . Thus food security for the world population of nine billion can be maintained .
" We are at this time was already producing enough food for 14 billion people . So we do not need a larger production capacity , but the quality and diversity . Mainly we have to choose the location of production close to the consumer , " said Herren , so as not to cause emissions additional waste due to food distribution activities .
