全球气候变化预示着水的需求和供应的变化，这可能会损害或导致缺水地区的部门间水资源重新分配。本研究调查气候变化对区域水资源需求和供应以及经济的影响，在圣安东尼奥得克萨斯州爱德华兹含水层区域。这是使用一个区域模型，描绘水文和经济活动。总体结果表明，气候条件的变化减少了水资源的可用性，增加了对水的需求。具体而言，气候变化可能导致每年220万至680万美元的区域福利损失。此外，如果要将泉水保持在目前所需的水平，以保护濒危物种，抽水必须减少9-20%，每年额外花费50万至200万美元。
Global climate change portends shifts in water demand and availability which may damage or cause intersectoral water reallocation in water short regions. This study investigates effects of climatic change on regional water demand and supply as well as the economy in the San Antonio Texas Edwards Aquifer region. This is done using a regional model which portrays both hydrological and economic activities. The overall results indicate that changes in climatic conditions reduce water resource availability and increase water demand. Specifically, a regional welfare loss of $2.2–$6.8million per year may occur as a result of climatic change. Additionally, if springflows are to be maintained at the currently desired level to protect endangered species, pumping must be reduced by 9–20% at an additional costof $0.5 to $2 million per year.
