The habitants of Baan Chetawaan, Tambon Santiam, Ampher Nanoi, Nan Province used to be farmers for long period. However, due to the change of climate causing long draught period which is unfavorable condition for agriculture in the area, the habitants can only grow corn plants to feed livestock. From this reason, the habitants had to invade more the forest area, to use herbicide and insecticide causing soil damage, and to burn the residual corn cob.

From the mentioned problems, the origin of all was lacking of water resources and this problem can be resolved by constructing the dam to store water for multi-purposes during the drought period.

From 2018 to 2021, the Visawapat student camp has continuously been in the areas with water shortage problem to construct the dam, sediment-trap dam, and water pipe to link agricultural area (total length is 1.4 km). By constructing these dams and water systems, the plantation of corn was reduced from 100 percent to alternative plants such as durian, cacao, and dates.
