Water – How to live without it? Relevance for life and distribution on the Planet Why are there conflicts and disputes for the water? In the XX century, the world population has tripled while the water consumption raised six times. Moreover, this natural resource distribution is not balanced around the planet.
Water around the world United Nation Organization (UNO) has statisticsshowing that each human being living in a community needs roughly 2.5 thousand cubic meters of water/inhabitant/year to perform his/her ordinary social and economic activities. In regions where water availability is below 1.5 thousand cubic meters inhabitant/year, the situation can be considered critical. In critical areas, the availability of water per person is only 3 cubic meters per day. At some regions in Brazilian Northeast, the water availability is 3.8 cubic meters by day. Water comsuption measure (water/inhabitant/day) considered ideal for tropical regions is around 200 liters.
