Water management policy
Worldwide consequences of poor water management
According to a United Nations report of 2006, there is enough water for everyone, but access has been hampered by corruption and mismanagement.
Over 2,200,000 people died in 2000 as a result of waterborne diseases. 1,200,000 people have no potable water.
Liters per capita per day: According to the World Health Organization, the biological minimum need to human survival is 5 litres in 24 hours. Each habitant has...
- in the USA: 425 l/day
- in Italy: 237 l/day
- in France: 150 l/day
- in Madagascar: 10 l/day
- Estimation of a Western family: 300 l/day
- Estimate of African family: 20 l/day
The poor water management aggravates the effects of drought.
Water is a global and crucial issue, it is, directly and indirectly, the first cause of death and disease on the world. Water is essential for the production of food from agriculture. More than a billion of people do not have access to drinking water, rural and peri urban areas being mostly faced by this issue. More then 30 % of natural catastrophes, 50 % of death, and 31 % of costs are due to floods. Current investments need to be doubled over the next 25 years in order to respond to economic development. Half of the large rivers and lakes suffer pollution, half of humid zones disappeared, biodiversity dramatically decreased in surface waters, groundwater is more and more overexploited and polluted. The demand is increasing but water resources are degrading, with a possible increase of this negative trend.
- Economic consequences: Increase the household expenditure, since the lack of water compelled to buy it
- Political consequences: Existence of numerous armed conflicts in which water is a key factor.
- Social consequences:
- Lack of awareness of the people about the importance of water
- People living in developing countries have increased fatigue and less time to spend with family because they have to travel long distances for water. There are fewer children in school because they have to use part of their time collecting water for her family.
- Aumento de la tensión y disminución de la autostima debido a la preocupacion de agua para vivir (hace falta traducirlo)
It is the policy designed to distribuye and administer water resources. The main cause of poor water management is the overexplotation and pollution of aquifers and wells, the abuse of water and the relationship between water resources, the level of contribution to national economy and population concentration.
One of the most used solution of the goverments is the construction of a desalination plant.
Melting of glaciers and poles
Altered water cycle
Conflicts for water
Our conclusion of this theme is that water is a natural right and that we shouldn’t make a business with it because the only things that we obtain are conflicts. But at the moment water is used as a business.
