Topic: Distribution of key natural resources across the world (including South Asia and the Indian subcontinent

Q2. Large reservoir projects alter regional geomorphology and hydrological cycles. Discuss the geographical implications and suggest strategies for sustainable development. (10 M)

Difficulty Level: Medium

Reference: TH

Why the question:
Officials of the Revenue and Forest departments are undertaking a survey to ascertain the extent of land that would get submerged owing to the Mekedatu balancing reservoir project proposed near Kanakapura,

Key Demand of the question:
The question requires discussing the geographical implications of reservoir projects on landforms and hydrological cycles, followed by suggesting sustainable strategies to manage these changes.

Structure of the Answer:

Introduction:
Briefly highlight how large reservoirs alter landforms, sediment flow, and regional water cycles, emphasizing their long-term environmental consequences.

Body:

  • Geographical Implications: Discuss impacts like altered river morphology, soil erosion, groundwater fluctuations, microclimatic changes, and biodiversity disruption.
  • Sustainable Development Strategies: Suggest measures like sediment management, environmental flow norms, slope stabilization, community-led conservation, and advanced monitoring systems.

Conclusion:
Emphasize the need for a balanced approach that integrates technological innovations with environmental safeguards to ensure sustainable reservoir development.
