BANGKOK, Thailand, Dec 23 (IPS) – In December 2024, Vanuatu experienced yet another harrowing reminder of its vulnerability to disasters—a powerful 7.4 magnitude earthquake struck the Pacific nation’s capital, Port Vila, leaving 14 dead, over 200 injured, and thousands more affected.
The devastating earthquake, compounded by overnight aftershocks and disrupted essential services, highlights the precarious situation faced by countries already grappling with the impacts of climate change and natural disasters.
Vanuatu is emblematic of the cascading disasters that Pacific Island nations increasingly endure, where frequent earthquakes intersect with the escalating impacts of climate-induced hazards such as cyclones, rising sea levels, and coastal erosion accompanied by staggering loss and damage experienced by vulnerable populations and ecosystems.
With every fraction of a degree of warming, the region’s diverse subregions—from the icy peaks of the Third Pole to the low-lying islands of the Pacific—are encountering unparalleled climate risks.
Recognizing these unique challenges, ESCAP launched the 2024 Asia-Pacific Subregional Disaster Reports to customize the insights and recommendations from the flagship Asia-Pacific Disaster Report 2023 to the distinct vulnerabilities and opportunities within each subregion.
Transformative insights: Shaping climate resilient futures
The 2024 subregional reports reveal escalating disaster risks across Asia and the Pacific, stressing that incremental actions are insufficient against intensifying climate impacts. East and North-East Asia has faced $2 trillion in economic losses and nearly half a million fatalities over five decades, with 2°C warming expected to exacerbate droughts, heatwaves, and floods in China, Mongolia and Korea, threatening urban centers and critical systems.
North and Central Asia faces growing multi-hazard risks in the Aral Sea Basin, where droughts, heatwaves, and floods will endanger agriculture and energy systems. In South-East Asia, nearly 100 per cent of the population is at risk of floods under 2°C warming, with the Mekong River Basin emerging as a persistent multi-hazard hotspot.
Pacific island nations face rising seas and stronger cyclones that erode coastlines, threaten biodiversity, and force communities to relocate, while South and South-West Asia grapples with glacial melt from the Third Pole, jeopardizing water security for 1.3 billion people.
Economic and social costs are mounting, with average annual losses (AAL) projected to rise under warming scenarios. East and North-East Asia’s AAL of $510 billion could increase further under 2°C warming, while the Pacific’s AAL exceeds $20 billion, with small island developing states like Vanuatu and Tonga suffering losses of over 21 per cent of GDP.
Despite these dire projections, the reports emphasize that investments in transformative adaptation—such as early warning systems, resilient infrastructure, and integrated climate policies—can mitigate risks and protect livelihoods across the region.
Early warning systems: A lifeline for resilience
A critical takeaway from the subregional reports is the transformative role of early warning systems (EWS) in disaster risk reduction. By providing timely and actionable information, these systems save lives and reduce economic losses. In South-East Asia, effective EWS could prevent $8.7 billion to $13.1 billion annually, while in the Pacific, they could avert $4 billion to $6 billion in damages each year.
EWS are especially vital in regions with complex multi-hazard risks, such as the Pacific small island developing States, where cyclones, floods, and sea-level rise intersect, and in South-East Asia, where urban flood risks are rapidly escalating.
For EWS to be fully effective, they must encompass four key pillars: risk knowledge, detection and monitoring, dissemination of warnings, and preparedness. Investments in these areas, combined with robust regional cooperation, can ensure that warnings reach the most vulnerable populations in time to act.
The reports highlight examples like impact-based forecasting in South and Southwest Asia and AI-powered risk assessments in China and Japan as transformative advancements in EWS implementation. These systems not only save lives but also help governments and communities reduce disaster recovery costs and safeguard economic stability.
Transboundary solutions: Collaborative action for shared risks
Transboundary risks like ocean-based hazards, inland water stress, and desertification demand collaborative solutions across regions.
1. Ocean-Based Climate Action:
Rising sea levels, intensified cyclones, and coastal erosion require collective efforts such as mangrove restoration and integrated coastal management. In the Pacific SIDS, ASEAN, and South-West Asia, platforms like the Pacific Resilience Partnership and Mekong Basin initiatives foster nature-based solutions to protect ecosystems and livelihoods.
2. Inland Water Systems:
The drying of the Aral Sea Basin in North and Central Asia highlights the importance of transboundary water-sharing agreements to combat drought and degradation. For Third Pole glacial melt, collaboration through the Third Pole Climate Forum is vital to safeguard water security for 1.3 billion people in South, South-West, and East Asia.
3. Desertification and Sand and Dust Storms:
Desertification and sand and dust storms (SDS) are accelerating across Asia. Countries like China, Mongolia, and Iran are advancing afforestation and land restoration, while regional frameworks promote sustainable land management to mitigate downstream impacts.
By prioritizing transboundary cooperation, countries can tackle shared risks, protect vulnerable communities, and build scalable solutions for resilience.
A call for transformative change
The 2024 subregional reports make it unequivocally clear: transformative, not incremental, adaptation is needed to combat the growing threats of climate change and disasters. This means embedding climate resilience in every sector—agriculture, energy, urban planning, and biodiversity conservation—while fostering regional cooperation to address transboundary risks.
By aligning local action with global frameworks like the Sendai Framework for Disaster Risk Reduction and the Paris Agreement, the Asia-Pacific region has an opportunity to lead the way in building a sustainable and resilient future. As ESCAP’s subregional reports demonstrate, the tools and knowledge are at hand. The time to act is now—before the risks become irreversible and the costs unmanageable.
