Experts: Jhum Cultivation Damages Assam’s Kohora River
The Kohora River in Assam is in trouble because of how people have used the land in the past.
Farming practices like 'jhum' cultivation and the growth of bamboo have hurt the soil and the river.
This, along with less rain and pollution, has caused the river to shrink and its water to become less clean.
Scientists and local communities are now working together to fix the river by planting trees and improving the land.
They hope to bring the river back to health for both the people and animals that depend on it.
Jhum cultivation, bamboo growth, and cotton farming have damaged the Kohora River Basin ecosystem.
Water levels in the Kohora River have decreased significantly due to reduced rainfall and deforestation.
Water quality is also affected by household activities and tourism in the area.
Aaranyak is tracking water quantity and quality and is working with the local community on restoration projects.
Restoration efforts include planting native trees and restoring forest floors to improve the river's health.
