Sustainable Management of Natural Resources

• Introduction to Resources

  • Natural Resources: Air, water, soil, forests, wildlife, coal, petroleum
  • Need for Management:
    • Limited availability
    • Growing human population
    • Equitable distribution
    • Long-term availability (sustainability)
  • The 3 R's: Reduce, Reuse, Recycle

• Why Do We Need to Manage Resources?

  • Conservation: Preventing over-exploitation
  • Environmental Protection: Reducing pollution and ecological damage
  • Intergenerational Equity: Saving resources for future generations

• Forests and Wildlife

  • Biodiversity Hotspots: Regions with high species richness
  • Stakeholders:
    • Forest Department: Government authority
    • Local People: Dependence for fuel, fodder, and shelter
    • Industrialists: Use forest produce as raw material
    • Wildlife Conservationists: Protect nature and wildlife
  • Case Studies of Conservation:
    • Chipko Andolan: Grassroots tree-hugging movement in Himalayas
    • Amrita Devi Bishnoi: Sacrifice for Khejri trees in Rajasthan
    • Arabari Forest Range: Successful participatory forest management in West Bengal

• Water for All

  • Importance: Essential for life and agriculture
  • Dams:
    • Advantages: Irrigation, electricity generation, flood control
    • Criticisms: Social problems (displacement), economic drain, environmental problems (deforestation, waterlogging)
  • Water Harvesting:
    • Ancient and local engineering solutions
    • Khadins, tanks, nadis (Rajasthan)
    • Bhandaras, tals (Maharashtra)
    • Ahars, pynds (Bihar)
    • Benefits: Recharges groundwater, provides drinking water, increases crop yield

• Coal and Petroleum

  • Origin: Formed from fossilized remains of ancient biomass over millions of years
  • Concerns:
    • Rapid depletion (limited reserves)
    • Environmental pollution (greenhouse gases, global warming, oxides of sulfur and nitrogen)
  • Judicious Use: Switching to cleaner and renewable alternatives (solar, wind, hydro)

• Overview of Sustainable Management

  • Integration of traditional knowledge with modern science
  • Reducing carbon footprint
  • People's participation as the core of resource conservation
