The map illustrates the development of a region between 1980 and 1990. The first map shows the are before the construction of a hydroelectric dam. The second map depicts the same area the dam was completed.
In 1980, there was a river flowing from north to south among the mountains. On the left side of the river, there was a forest, which was located in north of some structure architecture. Furthermore, some rare plants and animals were there near these structure. While, on the right side of the bank, the piece of irrigated land was spread along the river, near a village.
Now looking into future, the place experienced a significant change. In addition, the forests and structure architecture were removed. On the other hand, Irrigated land was replaced by hotel, the villages were shifted to the southeast. Moreover, a hydroelectric dam was also constructed in the south of the river. As a result the river was enlarge and finishing could be done there. Some electrical towers were made towards the south of the dam.
Overall, the place become modern and more functional for the people. However, some biodiversity had to be sacrificed.
