Positive and Negative impact on water

The positive impacts are demonstrated in the following possible benefits and uses of the multipurpose river valley projects:

  •  Provide work
  • Eliminate flooding
  • Provide power
  • Provide water for human consumption
  • Help to conserve water
  • Provide water for agriculture
  • Provide water for industrial use
  • Provide for a fishery where one may not have existed before
  • Changes the ecology of the region
  • Open new areas to agriculture
Negative impact may include

  • from small tribalThey lead to the displacement of human,plants,animals,chiefly  communities
  • disrupt downstream fisheries
  • Increase the risk of earthquake
  • Submerge forest land
  • Increase the spread of insect-bone diseases;and
  • threaten the fragile regional ecosystem through reducing,the flow of water from the rivers into the seas.
  • These projects initially devastate human lives and biodiversity by inundating thousands of acres of forest and agriculture land
  • They degrade the fertile agriculture soil due the continuous irrigation(rather than the seasonal irrigation which is dependent on the monsoon),and sensitization,making the soil toxic to many plant species.
So here are some pictures of the positive effects of rivers...

Fertile soil...


Industrial uses...

Negative effects of rivers...

Increases the risk of earthquake...

 Disrupt downstream fisheries...

Thank You! ^^
