Opinion: Keeping Pace with a Succession of Climate Shock Events

Context

• • South Asia is witnessing a succession of climate shock events—floods, landslides, cyclones and droughts—highlighting the region’s growing vulnerability to climate extremes. Recent Rasuwa floods in Nepal, following major floods in Pakistan, India and Sri Lanka, show that climate disasters are becoming a recurring regional challenge. The key concern is not only the frequency of disasters but also the unequal vulnerability of different communities and the absence of a sufficiently coordinated regional response.

Climate Change: Unequal Responsibility, Unequal Vulnerability

• • Nepal contributes only around 0.1% of global greenhouse-gas emissions, yet it faces severe consequences of climate-related disasters.
  • This reflects the principle of Climate Justice:

Historical Responsibility → Global Emissions

Climate Impacts → Disproportionately borne by vulnerable countries

• • Within countries too, vulnerability is unequal.
  • In Sri Lanka, the Malaiyaha Tamil community, particularly tea and rubber estate workers, has historically faced marginalisation and remains highly vulnerable to climate shocks.
  • Thus, climate change is not merely an environmental issue but also a question of social and economic justice.

Why is South Asia Highly Vulnerable?

A. Geographic Vulnerability

• • The region contains:
    • Himalayan ecosystems
    • Floodplains
    • Coastal areas
    • Monsoon-dependent agricultural systems
  • These expose populations to multiple hazards.

B. Socio-economic Vulnerability

• • Poor and marginalised communities often lack:
    • Secure housing
    • Financial savings
    • Insurance
    • Access to healthcare
    • Alternative livelihoods
  • Consequently, the same disaster can have very different impacts on different communities.

C. Repeated Climate Shocks

The region has recently experienced:

Pakistan floods (2022) → Indian floods → Sri Lankan cyclone (2025) → Nepal floods

The succession of events suggests that governments need to prepare not only for individual disasters but for multiple and repeated shocks.

Beyond Disaster Relief: Build Resilience

The Nepal experience demonstrates that post-disaster recovery involves more than rescue.

Challenges include:

• • Temporary displacement
  • Loss of livelihoods
  • Damaged infrastructure
  • Difficulty accessing workplaces
  • Delayed rehabilitation
  • Uncertainty regarding permanent housing

For example, affected communities in Sri Lanka continued to face livelihood and rehabilitation challenges months after the disaster.

Therefore:

Disaster Management must move from relief-centric to resilience-centric governance.

Need for Regional Cooperation

South Asian countries face shared ecological risks and cannot address them entirely in isolation.

A regional approach can focus on:

• • Early-warning systems
  • Climate and disaster data sharing
  • Joint disaster-response mechanisms
  • Cross-border humanitarian assistance
  • Climate-resilient infrastructure
  • Sharing of scientific and technological expertise
  • Regional climate-finance mechanisms

The idea of South Asia as an “ecologically interconnected system” is important because disasters do not respect political boundaries.

Climate Justice and Vulnerable Communities

Climate policies should prioritise communities with high exposure and low adaptive capacity.

Need for:

• • Targeted social protection
  • Climate-resilient livelihoods
  • Insurance and risk-transfer mechanisms
  • Safe housing
  • Accessible healthcare
  • Community-based disaster preparedness
  • Special attention to historically marginalised groups

This would make climate adaptation more inclusive and equitable.

Way Forward

• • Strengthen early-warning systems and last-mile connectivity.
  • Integrate climate risks into development planning.
  • Build disaster-resilient roads, housing and critical infrastructure.
  • Strengthen community-based disaster management.
  • Develop regional South Asian climate-response mechanisms.
  • Ensure adaptation finance reaches the most vulnerable.
  • Shift from post-disaster relief → preparedness → resilience → long-term adaptation.

Conclusion

The succession of climate disasters in South Asia demonstrates that climate change is no longer a distant environmental threat but a present governance and development challenge. The region needs to recognise its ecological interdependence and build a collective, equity-based and resilience-oriented response. “Climate resilience in South Asia requires not only stronger infrastructure, but stronger regional solidarity and climate justice.”
