Explain the physical processes responsible for the occurrence of flash droughts. Analyse their impact on agriculture and water resources. Suggest measures for effective drought risk management.

Topic: changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes.

Q2. Explain the physical processes responsible for the occurrence of flash droughts. Analyse their impact on agriculture and water resources. Suggest measures for effective drought risk management. (15 M)

Difficulty Level: Medium

Reference: DTE

Why the question

Flash droughts are emerging as a major climate hazard due to rising temperatures and changing rainfall patterns. Recent studies from Maharashtra highlight the need to understand their geographical processes and impacts.

Key Demand of the question

The question requires explaining the physical processes responsible for flash drought formation, analysing their impacts on agriculture and water resources, and suggesting suitable measures for effective drought risk management.

Structure of the Answer:

Introduction

Briefly define flash drought and highlight its growing significance as a rapidly intensifying hydro-climatic hazard under climate change.

Body

  • Physical processes: Explain the geographical and atmospheric processes responsible for flash drought occurrence.
  • Impact on agriculture and water resources: Analyse the consequences for crop production, irrigation, groundwater and overall water security.
  • Drought risk management: Suggest technological, institutional and ecosystem-based measures for reducing flash drought risk.

Conclusion

Highlight the need for science-based early warning systems and climate-resilient resource management to enhance drought preparedness.
