Environmental Problems and Degradation

  • Environmental problems are relatively new, arising after population explosion and industrialization
  • Earlier, demand for environmental resources was less than supply, so no environmental crisis occurred
  • Current reversal: increased demand for environmental resources but limited supply due to overuse and misuse

India's Environmental Challenges

  • India has abundant natural resources: fertile soil, rivers, forests, minerals (8% of world's iron-ore reserves)
  • Dichotomy of threats: poverty-induced degradation and pollution from affluence/industrialization
  • Priority issues: (i) land degradation, (ii) biodiversity loss, (iii) air pollution (especially vehicular), (iv) freshwater management, (v) solid waste management

Sustainable Development: Concept and Strategies

  • UNCED definition: 'Development that meets present needs without compromising future generations' ability to meet their needs'
