If water is exhausted, it can take hundreds, if you don't want to say thousands of years to recover the water source.Jude Smith, a biologist at the National Wildlife Reserve Mulleshoe outside Muleshoe, Texas , Looking at a large pile of sand gathered after a dust storm. Photo: Ap.In decades, Texas Panhandle (United States) covered by green cotton, corn and wheat. Water wells suck a thousand gallons of water (1 gallon = 3
.78 liters) per minute from Ogallala water floor seemingly bottomless, allowing farmers to cultivate despite frequent drought and summer heat. Now farmers face a difficult situation. The underground water source maintains livelihoods for many generations that are disappearing, which has created a different issue across the delta in the south of America: when there is no rainy or groundwater to germinate crops and land Can be swept away - like it happened during the dust storms (Dust Bowl) in the 1930s
"We have wasted water," said Black Tim, a farmer in the region to speak, remember how people Farmers irrigated when they are small. Black of Black can access water with the following pit excavator. Now, Black lucky sucks 50 gallons per minute from high pressure wells, about 122 meters deep. He bought a water-based water for the family because the wells were salty. Dynamic muscles of water floors, not only happening in Ogallala. California's central valley in central valley until India and China are depleted. But Ogallala is over 280,000 km2 - one of the world's largest storage floors - It is very important for farmers and farm owners in some areas of eight states of plain.amy Kremen, project director at the project Agriculture coordinated with Ogallala countries funded by the USA USDA Ministry of Agriculture, said the region produced nearly 1/3 of US crops and pet goods, affecting other agricultural sectors, small businesses, prices Treatment of land and community tax facilities. But because water is not easily recovered in most areas, if the water is exhausted, it can take hundreds, if not to say thousands of years to recover. In Texas, along with the regions of New Mexico and Oklahoma, the country is disappearing faster than other plaques
Rain is less frequent due to climate change means that regular groundwater is the only option for farmers that make them face difficult choices. Some farmers are planting trees that need less water or head Investing in irrigation systems is more effective. Others, such as Black, are replacing plants with livestock and meadows. Special use of land in place.Nick Bamert, owner of the seed company based in Muleshoe, specializing in native grasses, said: "There is a reason that mothers nature choose such plants in areas there. Native varieties ... will exist because they have experienced the coldest winter and the hottest dry summer ".Black, each grown mainly corn, now planted this grass in the corners of his fields, making copper Grass for livestock is growing and making the cover between wheat and grass products every year. He hopes that the transition to livestock will allow his biggest son, Tyler, survive On the land of Black grandparents who started planning 100 years ago. His small son, Trent is a data analyst near Dallas. "It's too difficult and without water," Black said. Loss of cultivated land dried cracked under his feet when Jude Smith overlooking Mullehoe National Wildlife Reserve, was established in the Great Depression and the period of American-winning storms (Dust Bowl) to Conservation of native grasslands and three lakes with water circuits. In mid-May, everything looks like hardening because there is almost no rain for a year. Smith said: rain may not do a lot of groundwater levels. But draft The original origin will become alive even though it is only dripping rain. In non-indigenous grass died during the drought, the native grass still lives, with a deep root of 4.6 meters to hold the land. In this summer, about 0.4 meters so far. Smith said, the reserve's lakes filled with water and streams began to work again. Meanwhile, the native grass sourses.Black, the owner of Mulleshoe land, said the summer rain does not alleviate long-term concerns about groundwater and drought. It was too late to help the spring crop germic, and farmers continued to water. The Meteorology Brad Rippey of USDA said almost certainly Texas Panhandle will continue to suffer from the prolonged droughts took place Throughout the Southwest area for 20 years. Farmers have called Smith to ask whether the conservation area can buy their land or not despite not allowed. "Everyone knows that ... water will run out Kiet, "Smith said as he drove through abandoned farms, the stumps marked the abandoned houses for a long time and rusted irrigation equipment.
