Question

the problems of jhum cultivation ​

Answer 1

→→Shifting Cultivation: Problems and Prospects: Clearing of jungles is the prerequisite of shifting. The felling of trees and clearing of bushes, however, accelerate soil erosion and accentuate variability of rainfall which may lead either to droughts or floods. The overall impact is the decline in soil fertility.

Answer 2

JHUM CULTIVATION

• For the regeneration of jungle 10 years needed, but now-a-days farmers come back in 4-5 years. Not enough time for regeneration.
• Jhum farming families always suffer from food, fuel and fodder problems, leading to poverty and malnutrition.
• Tons of biomass loss due to burning of trees.
• Tree burning leads to:-

1. Higher CO₂ , NO₂ and other greenhouse gases.
2. Higher run-off of rain water. Hence it causes drought and drinking water shortage.
3. Soil erosion and siltation in dams.
