Sea-Level Rise Threatens Pacific Health Infrastructure, Sparks Global Justice Debate

In November, Dr. Saia Ma’u Piukala, the World Health Organization’s regional director for the western Pacific and former Tongan health minister, observed seawater reaching the outer walls of the main hospital in Honiara, Solomon Islands. The facility is currently threatened, prompting plans for its relocation to higher ground, an undertaking described as massive and costly.

The Rising Health Burden

This direct impact on health services and patients is part of an increasing health burden driven by sea-level rise. This also includes water contamination, infectious disease spread, food insecurity, population displacement, and worsening mental health.

A Global Crisis and Call for Action

At the inaugural UN General Assembly meeting on sea-level rise in 2024, representatives from small island developing states and low-lying countries characterized the issue as a global crisis that endangers 1 billion people worldwide. They called upon governments globally to act to safeguard health and lives.

Samoa’s then Prime Minister, Afioga Fiamē Naomi Mataʻafa, stated that their lands are being consumed by the sea despite their minimal contribution to the global problem.

The Justice Question: Who Pays?

This urgent situation has led to the formation of a Lancet Commission on sea-level rise health and justice, co-chaired by climate negotiator Christiana Figueres. The commission comprises almost two dozen health and environment experts, including Dr. Piukala. A central challenge for the commission is determining who should bear the financial responsibility for rebuilding critical infrastructure in cities like Honiara, given the impacts from major polluting corporations and countries.

Dr. Piukala reported that 62% of health infrastructure in 14 Pacific island countries is located within 500 meters of the coast. He asserted that the consequences of inaction are too severe to disregard and that the evidence of climate-related health harm is overwhelming.

He concluded that health is ultimately a political choice.
