Table of Content

Unit 1: Introduction to environmental studies

  • Multidisciplinary nature of environmental studies
  • Scope and Importance; Need for public awareness.

Unit 2:  Ecosystems

  • What is an ecosystem? Structure and function of ecosystem; Energy flow in an ecosystem: food chains, food webs and ecological succession. Case studies of the following ecosystems:
  • Forest ecosystem
  • Grassland ecosystem
  • Desert ecosystem
  • Aquatic ecosystems (ponds, streams, lakes, rivers, oceans, estuaries)

Unit 3: Natural Resources: Renewable and Non-renewable Resources

  • Land Resources and land use change; land degradation, soil erosion and desertification.
  • Deforestation: Causes and impacts due to mining, dam building on environment, forests, biodiversity and tribal populations.
  • Water: use and over exploitation of surface and ground water, floods, droughts, conflicts over water (international and inter-state).
  • Energy resources: Renewable and non-renewable energy sources, use of alternate energy sources, growing energy needs, case studies.

Unit 4: Biodiversity and Conservation

  • Levels of biological diversity: genetic, species and ecosystem diversity; Biogeographic zones of India; Biodiversity patterns and global biodiversity hot sports.
  • India as a mega-biodiversity nation; Endangered and endemic species of India
  • Threats to biodiversity: Habitat loss, poaching of wildlife, man-wildlife conflicts, biological invasions; Conservation of biodiversity: In-situ and Ex-situ conservation of biodiversity.
  • Ecosystem and biodiversity services: Ecological, economic, social, ethical, aesthetic and informational value.

Unit 5: Environmental Pollution

  • Environmental Pollution: types, causes, effects and controls, Air, water, soil and noise pollution
  • Nuclear Hazard and human health risks
  • Solid waste management: Control measures of urban and Industrial waste

Unit 8: Field work

  • Visit to an area to document environmental assets: river/forest/flora/fauna etc.
  • Visit to local polluted site – Urban/Rural/Industrial/Agricultural
  • Study of common plants, insects, birds and basic principles of identification.

Study of simple ecosystems – pond, river, Delhi ridge etc.
