1. Pollution is when something is added to the envionment that is harmful or poisonous to living things. Smoke in the air from factories is a type of pollution as it is bad for the lungs when breathed in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep or relax.

10. Pollution Micro level dispute Contending Water Uses: Population Growth and Demand THE POTENTIAL CAUSES Dams and Displacement Transboundary dispute Privatisation

11. LESSONS LEARNED: • Water crossing international boundaries can cause tensions between nations that share the basin. While the tension is not likely to lead to warfare, early coordination between riparian states can help ameliorate the issue. • A gradual decrease in water quantity or quality, or both, is more likely than violent conflict. Over time, such water decreases can affect the internal stability of a nation or region, and act as an irritant among ethnic groups, water sectors, or states/provinces. The resulting instability may have effects in the international arena. • The greatest threat of the global water crisis to human security comes from the fact that millions of people lack access to sufficient quantities of water of sufficient quality for their well-being.

12. “But the water problems of our world need not be only a cause of tension; they can also be a catalyst for cooperation…If we work together, a secure and sustainable water future can be ours.” Kofi Annan, February 2002 CONCLUSIONS: 1. An institutional framework for joint management and dispute resolution 2. Early intervention is also beneficial to the process of conflict resolution 3. Water disputes can be resolved through active dialog among disciplines.

13.  Inviting private sector participation in dam and reservoir projects  Opposition to the idea of `privatisation of water'  Privatisation poses a threat to that commitment because once privatised, water will no longer be provided on the basis of need but on the ability to pay
