Regional Water Demand Scenarios, 2005-2050Conducted by SIU Carbondale on behalf of CMAP, this study reveals important consequences of population growth for the region by the year 2050. It generates three water demand scenarios by major water user sectors and geographical subareas within the region. The scenarios represent water withdrawals under a current trends or "baseline" scenario (CT scenario) as well as under a less resource intensive (LRI) scenario and a more resource intensive (MRI) scenario. While the CT scenario assumes a continuation of recent trends for the variables modeled, resulting in a 36% overall increase in water withdrawals by 2050, the region's public water supply needs could grow up to 55 percent by 2050 under the MRI scenario.
