Answer: Built dams on rivers
Explanation:
Drought is a condition in which the region experience very low precipitation. This results in making the environment hot and dry.
Dams are the constructions over the rivers and other fast flowing water bodies. Dams are the ways to meet the demand for water, specifically when the region receives very low precipitation and runoff patterns are fluctuated due to climate change. The dams usually makes a boundary around the water body and the flow of the water body is utilized by the dams to generate electrical energy. This process conserves the water of the water body against over-exploitation by human society and restricting the flow of water so that flood can be prevented.
On the basis of the above description, built dams on rivers is the correct option.
