List three proble

Three problems that arise due to construction of big dams:

(i) Social problems. Due to the construction of high rise dams, a large number of human settlements are submerged in the water of large reservoir formed by the dam and many people are rendered homeless.

(ii) Environmental problems. The construction of high-rise dams leads to deforestation and loss of bio- diversity as vast variety of flora and fauna get submerged in the water of large reservoir formed by the dam and disturbs ecological balance.

(iii) Economic problems. Some people believe that the construction of high-rise dams involves the spending of huge amounts of public money without the generation of proportionate benefits.

Suggestions for these problems. All the people who are displaced from the dam site should be given adequate compensation by the Government for rehabilitation so as to start their life afresh.
