In 2020, a three-year study at the University of Plymouth which looked at the Maldives and the Marshall Islands, found that tides move sediment to create a higher elevation, a morphological response that the researchers suggested could help low-lying islands adjust to sea level rise and keep the islands habitable. The research also reported that sea walls were compromising islands' ability to adjust to rising sea levels and that island drowning is an inevitable outcome for islands with coastal structures like sea walls. Hideki Kanamaru, natural resources officer with the Food and Agriculture Organization in Asia-Pacific, said the study provided a "new perspective" on how island nations could tackle the challenge of sea-level rise, and that even if islands can adapt naturally to higher seas by raising their own crests, humans still needed to double down on global warming and protection for island populations.
