Vulnerability to Sea Level Rise Index Score (0-1)

The Sea Level Rise Vulnerability Index measures the susceptibility of countries to rising sea levels, a critical consequence of climate change. This dataset ranks nations based on their exposure, highlighting regions at high risk and those with better adaptive capacity.

Which countries are most vulnerable to sea level rise?

Netherlands leads the rankings with a vulnerability index score of 0.5541, followed by Bahrain (0.3717) and Vietnam (0.1547). These countries face significant risks due to their low-lying geography and heavy dependence on coastal infrastructure.

Top 10 countries most at risk of sea level rise

The ten countries most vulnerable to rising sea levels are:

1. Netherlands – 0.5541
2. Bahrain – 0.3717
3. Vietnam – 0.1547
4. Singapore – 0.1472
5. Denmark – 0.1181
6. Qatar – 0.0956
7. Kuwait – 0.081
8. Belgium – 0.0712
9. Laos – 0.0664
10. Bangladesh – 0.0618

These nations are particularly vulnerable due to their coastal geography, high population density in low-lying areas, and reliance on coastal economies.

Which regions show resilience against sea level rise?

Countries like Jordan, Syria, and DR Congo have the lowest index scores, with near-zero vulnerability. Their inland geographies and limited coastal exposure contribute to their resilience against sea level rise.

Why are some countries more vulnerable to sea level rise?

Vulnerability to sea level rise depends on factors like geography, coastal population density, and reliance on coastal infrastructure. Countries with extensive coastlines, low-lying areas, and weak flood defenses are at higher risk of inundation and economic disruption.

How does sea level rise affect food security?

Rising sea levels can lead to salinization of agricultural lands, loss of arable land, and displacement of coastal communities, directly impacting food production and security. It also disrupts fisheries and aquaculture, vital for food supplies in many regions.

What measures can mitigate sea level rise vulnerability?

Mitigation strategies include constructing robust flood defenses, implementing managed retreat plans, restoring natural buffers like mangroves and wetlands, and enhancing urban planning to minimize coastal risks. Investments in climate adaptation and international cooperation are critical for high-risk nations.

What global trends emerge from the Sea Level Rise Vulnerability Index?

Low-lying nations, particularly in Asia and Europe, show higher vulnerability scores due to extensive coastlines and significant coastal populations. Conversely, landlocked or inland countries like Jordan, Syria, and DR Congo exhibit minimal risk. These disparities highlight the importance of targeted climate adaptation strategies for coastal regions.
