Marshall Islands: New Climate Study Visualizes Confronting Risk of Projected Sea Level Rise
SYDNEY – Rising sea levels in the atoll nation of Marshall Islands are projected to endanger 40 percent of existing buildings in the capital, Majuro, with 96 percent of the city at risk of frequent flooding induced by climate change, according to a new World Bank study.
Jointly produced by the Government of the Republic of Marshall Islands and the World Bank, Adapting to Rising Sea Levels in Marshall Islands provides alarming visual projections, together with adaptation options to assist the atoll nation in tackling rising sea levels and inundation over the next 100 years.
As COP26 begins in Glasgow, the new visualizations demonstrate the existential threat the Marshall Islands faces from climate change. Should existing sea level rise trends continue, the country will confront a series of increasingly costly adaptation choices to protect essential infrastructure, such as schools, hospitals, and government buildings.
“These new visual models – which collect and connect many layers of data that were never available before – provide Marshall Islanders with detailed insights into the likely impacts of rising sea levels on densely populated parts of the country,” said World Bank Senior Municipal Engineer and leader of the study, Artessa Saldivar-Sali.
“These insights are critical for decision-makers to understand the potential short-, medium- and long-term benefits of adaption options, such as sea walls, nature-based solutions and land raising, and how each could mitigate the threat posed by rising sea levels and ultimately protect Marshallese homes, livelihoods and way of life.”
By providing a building-by-building breakdown of what various increases in sea levels would mean for the atoll nation, policy makers and the public can see when specific locations – down to schools, clinics, government buildings and individual communities – would become inundated, uninhabitable, and unusable.
Saldivar-Sali said the modelling paints a clear picture of the need for significant investment in adaptation for, and by, atoll nations like Marshall Islands.
“While it is important to show that there are low-cost options that can make meaningful differences immediately, these new visualizations clearly highlight that under extreme scenarios more transformational measures like land reclamation or even migration may become necessary,” she said.
Adapting to Rising Sea Levels in Marshall Islands has been released as Marshall Islands’ delegation prepares for COP26, with representatives planning to use it to paint a clear picture of what atoll nations are facing, and to encourage other nations to strengthen their Nationally Determined Contributions.
“Our people know the imminent threats posed by rising sea levels, but for others at these major events; the impacts of climate change may be more abstract. With a powerful tool like this, we can help to bridge that understanding,” said Marshall Islands Climate Change Directorate Director, Clarence Samuel.
“It is important that the tool highlights there are still adaptation options open to us, but action must be taken to avoid those last resorts, such as migration,” added Mr. Samuel.
Adapting to Rising Sea Levels in Marshall Islands and the related Legal Dimensions of Sea Level Rise report are parts of a wider body of work, funded by the Global Fund for Disaster Reduction and Recovery (GFDRR), to provide at-risk atoll island nations with evidence of the scale of the threat posed by climate change, together with clear indications of what decisions and investments could be made to protect their homes, livelihoods and way of life.
The World Bank works in partnership with 12 countries across the Pacific supporting 87 projects totaling US$2.09 billion in commitments in sectors like agriculture, health, education and employment, climate resilience and adaptation, energy, fisheries, rural development, economic policy, macroeconomic management, aviation and transport, telecommunications and tourism.
