Oct 5, 2020 · In the US High Plains, which produces more than 50 million tons per year of grain, as much as 90% of irrigation originates from groundwater resources, including the Ogallala aquifer. In parts of the High Plains, groundwater resources are being depleted so rapidly that they are considered nonrenewable, compromising food security. May 4, 2020 · The High Plains Aquifer (HPA) in the United States (US), also known as Ogallala Aquifer, is spread over an area of 450,658 km 2. Being one of the world’s largest aquifers, it serves as the primary source of water for millions of people living in Texas, Oklahoma, Kansas, New Mexico, Nebraska, Colorado, Wyoming, and South Dakota [ 1 ]. The agriculture of the Texas High Plains (THP) region is primarily dependent on groundwater irrigation. Changing weather patterns along with competing demands for water resources and other anthropogenic effects have dramatically increased withdrawals from the Ogallala aquifer. In addition to on-farm changes, policy tools based on off-farm mechanisms are equally indispensable in addressing ...12201 Sunrise Valley Drive, MS 413. Reston, VA 20192-0002.
