摘要：Water has shaped nations for centuries. However as populations have expanded and economies grow, the demand for water has increased substantially. Large amounts of water are needed for agriculture, power and daily living. This water is often removed from the downstream hydrologic cycle exacerbating current water shortfalls. There are a variety of means to address water demands. However they are disproportionately placed on urban users as those users are the easiest to measure and regulate. Urban users are asked to curtail water use, convert to alternative sources and can be regulated on per capita water use. Per capital water use is often used to show where there is “wasted” water use, usually in the form of excessive irrigation. Most such communities are distinctly urban-large areas with large and diverse populations, which often include a large tourist contingent. However such a metric may penalize successful communities with diverse economic bases, thereby limiting the potential for these urban communities to grow their economies and forcing local officials into difficult decisions with respect to growth, development and job opportunities for their residents. The issue is particularly significant because urban use is only 12.6% of total water use in the United States.
