adverse effect on the fertility of soil: due to the construction of dams there are no annual floods in the river and because of this the soil of the downstream region does not get nutrient rich silt this decreases the fertility of the soil
adverse impact on aquatic life: due to the construction of dams on the river the fish in the downstream area do not get sufficient nutrient material regulating and damming of rivers affect the natural flow of water causing post sediment flow downward and excessive sedimentation at the bottom of the Reservoir resulting in rockier stream beds and poorer Habitat for the rivers aquatic life dams also fragment river making the difficult for aquatic fauna to migrate for spawning
displacement of local communities: the building of large dams result in displacement of local communities the local people often have to give up their land and livelihood and their meager acces control over resources for the greater good of the nation
change in the cropping pattern: the multipurpose projects are responsible for providing assured means of irrigation to farmers due to this most of the farmers have changed the cropping pattern shifting to water intensive and commercial crops that has led to salinization of soil leading to ecological imbalance
