Discuss the population growth and the pressure of population on the resources in India.

Introduction: India has surpassed China to become the world's most populous nation (~1.43 billion). Rapid population growth places unprecedented ecological, economic, and infrastructural stress on the nation's finite natural resources.

1. Manifestations of Population Pressure on Natural Resources:

• 1. Severe Stress on Freshwater Resources:
  • Per capita water availability plummeted from $sim 5,177 ext{ m}^3$ in 1951 to $sim 1,486 ext{ m}^3$ today (entering water-stressed status), causing critical groundwater depletion across Punjab, Haryana, and peninsular cities.
• 2. Land Degradation & Decreasing Agricultural Land:
  • Average agricultural landholding size has fragmented to less than 1.08 hectares (small/marginal farmers).
  • Over-cultivation and chemical overuse trigger soil erosion, salinization, and loss of soil organic carbon.
• 3. Deforestation & Biodiversity Loss:
  • Encroachment on forests for urban expansion, highways, and mining causes habitat fragmentation and human-wildlife conflict.
• 4. Energy and Mineral Depletion:
  • Surging demands for fossil fuels (coal, crude oil) escalate greenhouse gas emissions, air pollution, and massive import dependency.
• 5. Urban Sprawl & Waste Generation:
  • Proliferation of slums, unmanaged municipal solid waste (62+ million tonnes annually), and severe air quality crises in metropolitan cities.

2. Sustainable Mitigation Strategies:

• Promoting circular economy principles, renewable energy transitions (500 GW non-fossil by 2030), water harvesting (Catch the Rain), and converting population size into a skilled Demographic Dividend.

Conclusion: Aligning population dynamics with sustainable resource carrying capacity is essential for realizing Viksit Bharat @ 2047.
