Water footprint an important gauage

Posted by aqua 2263 days ago in Planning and Management from http://www.contracostatimes.com

Recent research by Hockstra & Chapagain suggests that the water footprint of nations depend on several factors. These include:

1. High per person income and consumption - This partially explains the high water footprint for the U.S., Switzerland, and Italy;

2.High meat consumption - This explains the high water footprint of countries such as the U.S., Canada, France, Spain, Portugal, Italy and Greece. The average meat consumption in the U.S. is three times that of the average worldwide meat consumption;

4. Climate - Countries with high rates of evaporation have high water footprint. These include Senegal, Mali, Sudan, Chad, and Nigeria.

5. Water inefficient agricultural practices - This also partially explains the high water footprint of countries such as Thailand, Cambodia, Sudan, Mali and Nigeria. In Thailand for example, between 1997 and 2001, rice yield was 2.5 tons per hectare compared to the global average of 3.9 tons per hectare.
