The paper "Anit-Dam Movements" is an outstanding example of an environmental studies research paper. A dam is an artificially constructed barrier across a river with an intention of either to produce hydro-electric power, to store water for irrigation or to control floods during the rainy season. Despite the fact that dam construction is very important to both citizens of the state and economic development of the state, the construction of big dams also has a negative impact on the environment. The researchers interested in finding a solution for global environmental change figured out that large dam has a great negative impact on the environment (Draper, 2003, p.
205). The negative impact of large dams on the environment includes; starving of the river, the distinction of species of aquatic lives, the spread of diseases to the surrounding people, reduction in aquatic animals due to the interference in their migration routes thus blocking them from reaching their breeding regions. In addition to that, dam construction destroys debris and erodes sediment on the downstream of the river thus making it unsuitable for aquatic life.
Lastly, is that water held in the reservoir above the dam structure causes climatic change to the region around the dam making it unsuitable for human life. Based on the above negative impact of the construction of large dams on the environment, many anti-dam construction groups have been formed by nations, international agencies and NGOs to fight against big dam construction. The anti-dam movements that were formed include; The Assam anti-dam government was formerly formed by five ministers, the China Anti-Dam Movement, the anti-dam movement that was formed in Korea to protest against Naerin Stream Dam Construction, The Sarawak PKR chief Baru Bian has also been a supportive person that has protested against the dam construction plan that was put in place by the Sarawak government and has managed to report this activity to the United Nations for help, Greater Anti-Dam Citizens' Committee China. Table of Contents: Introduction: Analysis of different types of dams: Effects that dam construction has on the environment: The Anti-Dam Movements: Reasons for dam construction: Conclusion & Recommendation: References: Introduction: A dam is a barrier constructed across a river to hold water for a number of reasons such as; to control the flow of water downstream, to store water for irrigation purpose, to raise the drop of water for it to drive turbines for hydro-electric power generation, to control flooding of the river during the rainy season.
Despite the importance that dam construction has on the people and the economic growth of the state, it also has negative impacts on the environment (Marsha, 1998, p. 104). This paper would analyze look at the types of dams, the importance of dams to the people and the state in general, negative impact that dam construction has on the environment, the anti-dam movements that have been formed by international and regional agencies, a conclusion and recommendation. Analysis of different types of dams: A dam is an artificially constructed barrier across a river with an intention of; controlling water flow, hydro-electric power generation, flood control downstream during the rainy season, water storage for irrigation purposes.
There are two main categories of dams which are; large dams and small dams. Large dams are like the Grand Canyon Dams, the three (3) Gorges Dam on Yangtze River and the Franklin River Dam.
