The Shortage Of The Water

  1. 1. The shortage of the water: world problem <ul><li>Where as in many places the clean and fresh water gives itself made, in others it is a scanty resource due to the water lack or the pollution of his sources. Approximately 1.100 millions of persons, that is to say, 18 per cent of the world population, do not have access to sure sources of drinkable water, and more than 2.400 million persons lack suitable reparation </li></ul>
  2. 2. Effects of the problem <ul><li>The quality of the water will deteriorate with the elevation of his temperature and the increase of the indexes of pollution. Already in the last years an important decrease has been demonstrated in his quality. And the most affected continue being the poor, since 50 % of the population of the underdeveloped countries is exposed to the danger that the water sources represent contaminated. </li></ul><ul><li>Other very important problems that appear are those of the quality and the good administration of the water. In the world there are more than 2,2 million persons who die every year due to diseases caused by the drinkable contaminated water and a deficient reparation. A great proportion of these deaths owes to the diseases caused by the water. </li></ul>
  3. 3. The affected more: the children <ul><li>Every day thousands of children spends great part of his time in the waters contaminated with the rivers that cross the poorest countries of the planet. </li></ul><ul><li>Others, on the other hand, plunge to approach the cruises that, loaded with tourists, navigate these rivers full of history and misery. </li></ul><ul><li>If the present appears to small these shaded, the future begins to show even more discouraging. The Earth faces in this beginning of the century twenty-one a serious crisis of the water. </li></ul>
  4. 4. Why scanty the water? The lack of drinkable water owes, principally, to two reasons: CARENCIA DE AGUA EN EL MUNDO falta de inversiones en sistemas de agua mantenimiento inadecuado
  5. 5. THE WORST POLLUTANT: THE AGRICULTURE <ul><li>The agriculture is the sector that more pollution produces, even more that the industries and the municipalities. In practically all the countries in those who apply agricultural fertilizers and pesticides to themselves, aquiferous undergrounds and the surface water have been contaminated. The animal tailing are another persistent pollution source in some zones. </li></ul>In The United States, the chemical products used in the agriculture, the sediments of the erosion and the animal tailing they have dirtied more than 278.000 kilometers of waterways. It is said that the agriculture is responsible for 70 % of the current pollution of the water in the United States.
  6. 6. Shortage of water and water tension The population in countries with shortage of water and water tension, 1995 - 2050 0.46 2.8 4.0 POPULATION Miles de millones
  7. 7. Possible solutions of the shortage of the water <ul><li>These are the fundamental forms of solutions: </li></ul><ul><li>preserve water </li></ul><ul><li>reduce the pollution </li></ul><ul><li>regulate the supply and the demand </li></ul><ul><li>contain the growth of the population. </li></ul><ul><li>To desalinate the water of sea </li></ul>
  8. 8. <ul><li>On March 22 of every year it is celebrated the World Day of the Water </li></ul>Key information on the water: <ul><li>The General Assembly of the United Nations adopted on December 22, 1993 the resolution A/RES/47/193 the one that on March 22 of every year was declared World Day of the Water, to be celebrating from 1993. </li></ul><ul><li>The water quantity that exists in the Earth reaches 1.385 millions of km3. </li></ul><ul><li>1.1 Billion persons lack water in the world </li></ul>
  9. 9. WATER CONSUMPTION IN THE WORLD <ul><li>If the consumption of water resources per capita continues growing to the current pace, in 25 years the man might manage to use more than 90 per cent of the sweet available water, leaving only 10 per cent for the rest of species that populate the planet. </li></ul><ul><li>Nowadays, on a worldwide scale: </li></ul><ul><li>69 % of the annual extraction of water for human use is destined to the agriculture (principally for irrigation) the industry represents 23 %; and the domestic consumption (home, water to drink, reparation) represents approximately 8 %. </li></ul>
