The use of water footprint for water management
As we study in Environment Science Today World subject, we are interested in the Water footprint, which is the instrument for calculating how much water that we used. Nowadays, we know that some countries have floods and others lack of water. This indicates some problems of water management. While there are some problems, there is the use of water footprint for water management.
There are three main factors that indicate the problem of water management. Frist of all, there is limited fresh water in the world. Gleick tells in Water resources, in Encyclopedia of Climate and Weather, in 1996 that surface-water sources, such as river, only constitute about 300 cubic miles that is 1/10000 th of one present of total water, but not all of fresh water that we can consume. We not only face with the limiting fresh water, but we also we face with lacking of clean water for human activities such as drinking, cleaning, agriculture etc. Moreover, we don’t have enough clean water for every part of the world. The http://water.org/ shows that there are some developing country women spend 200 million hours day collecting water for their family consumed, though sometime the water that they found is not pure water that is why many people around the world have diseases or die because of using dirty water and poor sanitation. Lately, the amount of water used by a household, a country or using the production is high. The Global Compact presents that the demand for water among industry and agriculture is increasing significantly due to population growth and economic development. The data from the Water Footprint Network (WFN) shown in 13 January 2013 on water consumption in the world is provided by the United Nations that agriculture accounts for 70% of all water consumption, compared to 20% for industry and 10% for domestic use.
