It is worrisome that we would be talking of water crisis, scarcity or problems when two-third of our world is composed of water. Of the whole bulk of water on earth, only 2.5 per cent is fresh and suitable for human and agricultural use. This makes usable water a finite resource. Of this 2.5 percent, 99 per cent is held up in icebergs, glaciers or underground. Only 1 per cent of freshwater is therefore available to the nearly 7 billion human population and a countless other forms of life.
This tiny fraction of freshwater is unevenly distributed throughout the world. So, some people have much, while others have almost none. In some countries like Nigeria and Mali, quantity is not a problem, but distribution and quality are. This is commonly so in developing nations.
Each year, about 3.575 million people die from water-related disease. Million of people die globally from poor sanitation and contaminated water. Ninety per cent of the victims are children. Over a third of the world's population is seriously affected by water and sanitation crisis.
While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold. Within the next fifty years, the world population will increase by another 40 to 50 %. This population growth, coupled with industrialization and urbanization, will result in an increasing demand for water and will have serious consequences on the environment. Thus, the water crisis would continue to heighten.
People Lacking Water
More than one out of six people lack access to safe drinking water, namely 1.1 billion people, and more than two out of six lack adequate sanitation, namely 2.6 billion people 3900 children die every day from water borne diseases. One must know that these figures represent only people with very poor conditions. In reality, these figures should be much higher.
As the resource is becoming scarce, tensions among different users may intensify, both at the national and international level. Over 260 river basins are shared by two or more countries. In the absence of strong institutions and agreements, changes within a basin can lead to trans-boundary tensions. When major projects proceed without regional collaboration, they can become a point of conflicts, heightening regional instability. The Parana La Plata, the Aral Sea, the Jordan and the Danube may serve as examples. Due to the pressure on the Aral Sea, a good proportion of the water has disappeared
Towards A Way to Improve the Situation
The water crisis witness today is not about having too little water to satisfy our needs but rather a crisis of bad management of water.
With the current state of affairs, corrective measures still can be taken to check the worsening situation. There is an increasing awareness that our freshwater resources are limited and need to be protected both in terms of quantity and quality. This water challenge affects not only the water community, but also decision-makers and every human being.
Whatever the use of freshwater (agriculture, industry, domestic use), huge saving of water and improving of water management is possible. Almost everywhere, water is wasted, and as long as people are not facing water scarcity, they believe access to water is an obvious and natural thing. With urbanization and changes in lifestyle and attitude, water consumption is bound to increase. However, changes in food habits, for example, may reduce the problem, knowing that growing 1kg of potatoes requires only 100 litres of water, whereas 1kg of beef requires 13 000 litres.
Trans-boundary Cooperation
As far as trans-boundary conflicts are concerned, regional economic development and cultural preservation can all be strengthened by states cooperating on water-related issues. Instead of a trend towards war, water management can be viewed as a trend towards cooperation and peace. Many initiatives are launched to avoid crises. Institutional commitments like in the Senegal River are created.
Water Crisis Facts
43% of water-related deaths are due to diarrhea.
84% of water-related deaths are in children ages 0 - 14.
98% of water-related deaths occur in the developing world.
884 million people, lack access to safe water supplies, approximately one in eight people.
The water and sanitation crisis claims more lives through disease than any war claims through guns.
At any given time, half of the world's hospital beds are occupied by patients suffering from a water-related disease.
