Q

Factors leading to forest depletion

A
  1. Colonial era: expansion of railways, agriculture, commercial and scientific mining and forestry
  2. Post independence: agricultural land
  3. Enrichment plantation: teak, chir pine
  4. Dolomite mining: buxa tiger reserve in WB (had blocked migration routes)
  5. Large scale developmental projects: Narmada Sagar Project in MP
  6. Grazing + fuelwood collection: most is via lopping and not felling

Q

Social impacts of biological loss

A
  1. Marginalise and impoverish indigenous communities that depend on forests for livelihoods, medicine, culture, spirituality etc
  2. Women, typically assigned the job of collecting firewood, fodder and water in rural families, are worst affected by depletion of resources as they are forced to walk great distanced. Leads to health issues and neglect of children
  3. Environmental crises like floods and droughts affect the poor the hardest and directly cause poverty

Q

Why do we need conservation

A
  • preserves ecological diversity
  • preserves our life systems: air, water, soil
  • preserves genetic diversity for better growth of species and breeding
    ex: agriculture dependent on traditional crop varieties, fisheries
