What problems can arise after a dam is built. How can they be solved?
Problems that arise after a dam is built include:
(1) Flooding of land that was once home to animals and people, forcing them to leave their homes and relocate.
(2) Disruption of natural river flow and damage to river ecosystems.
(3) Harm to forests and wildlife habitats that get submerged.
(4) Impact on fish migration and aquatic life.
Solutions to these problems include:
(1) Proper rehabilitation and resettlement of displaced people with fair compensation.
(2) Creating wildlife sanctuaries and protected areas elsewhere to conserve displaced animals.
(3) Building fish ladders or passages to allow fish migration.
(4) Careful planning before construction to minimise environmental damage.
(5) Involving local communities in decision-making about dam projects.
Explanation
The chapter explains that while dams store water and help people during dry seasons for drinking, growing crops, and making electricity, they also cause significant problems. A dam is like a giant wall that blocks the river's flow and stores water in a reservoir, which floods land that was once home to animals and people. Many have to leave their homes and shift elsewhere when dams are built. The chapter emphasises the importance of using water wisely because of the many sacrifices made to provide it.
