Abstract

In the 20th century, the world's population has doubled, while human water consumption has increased five times. Many countries in the world are facing a water crisis. To measure the water supply capacity of a region, we define the water supply capacity index. Then we select 11 important factors according to systematic investigations and assume that the water supply capacity of the 12 chosen regions is only affected by the 11 chosen factors. We use Principal Component Analysis to calculate the principal components of collected data and their contribution rate, then linearly combine the value of them to get the water supply capacity index of the 12 chosen regions. The results reveal that South Asia has the best water supply capacity, Australia and New Zealand, Southern America, Eastern Europe and Russian Federation have a poor water supply capacity.
