Life at the Water’s Edge: Lancet Commission to Tackle Sea-Level Rise, Health, and Justice

A new global Commission led by The Lancet has brought together 26 leading experts to examine the far-reaching health impacts of rising sea levels and to advance equitable, evidence-based responses to one of the most pressing challenges of our time.

Titled “Life at the Water’s Edge: The Lancet Commission on Sea-Level Rise, Health, and Justice,” the initiative marks the first comprehensive effort to address sea-level rise through a public health lens—highlighting its profound implications not only for the environment, but also for human wellbeing, equity, and global stability.

Sea-level rise, driven by anthropogenic climate change, is already reshaping lives and ecosystems worldwide. The Commission underscores alarming projections:

• Up to 410 million people could be living on land below high-tide levels by 2100
• Hundreds of millions may be displaced by the end of the century
• Increasing threats to food and water security
• Changing patterns of infectious diseases
• Rising risks of flooding, livelihood loss, and freshwater contamination

Coastal and low-lying communities—often among the least responsible for climate change—are expected to bear the heaviest burden.

Health, Equity, and Justice at the Core

Convened with support from the WHO Asia-Pacific Centre for Environment and Health (WHO ACE), the Commission aims to deliver science-led policy recommendations to:

• Mitigate health risks
• Strengthen climate adaptation and resilience
• Ensure equitable and ethical global responses

It brings together experts across disciplines, combining scientific research with policy insight and community perspectives to influence global decision-making platforms.

Global Leaders Speak

Prominent voices leading the Commission have emphasized the urgency and human dimension of the crisis:

• Saia Ma’u Piukala, WHO Regional Director for the Western Pacific, stressed that sea-level rise impacts “are deeply human,” affecting everything from mental health to economic survival, and called for a unified global response.
• Christiana Figueres, former UNFCCC Executive Secretary and Co-Chair, warned that sea-level rise is no longer a distant threat but a present reality disrupting vulnerable populations. She highlighted both the “staggering cost of inaction” and the opportunity to place human and planetary health at the center of global efforts.
• Kathryn Bowen, Co-Chair and Deputy Director at Melbourne Climate Futures, described sea-level rise as a “measure of injustice,” disproportionately impacting those least responsible for climate change.
• Jiho Cha, Member of Parliament, Republic of Korea and Co-Chair, called it a defining policy challenge, emphasizing the need for urgent and fair action.
• Dr. Sandro Demaio, Director at WHO ACE, declared sea-level rise a “public health emergency unfolding now,” warning that inaction is a deliberate choice that endangers lives and justice.

A Defining Challenge of Our Time

Beyond environmental damage, the Commission highlights how rising seas threaten:

• Human settlements and cultural heritage
• National economies and infrastructure
• Public health systems
• Social equity and global justice

By integrating science, policy, and lived experiences, the Commission seeks to reshape global understanding and drive coordinated action.

Looking Ahead

As sea levels continue to rise, the Commission aims to play a key role in shaping international dialogue and influencing policy frameworks across global platforms.

Its core message is clear: sea-level rise is not just an environmental issue—it is a profound human, health, and justice challenge that demands immediate, inclusive, and science-driven action.
