Seagrass Meadows Sustain Millions in Indo-Pacific Poverty, Study Finds

A new large‑scale study has confirmed that seagrass meadows serve as a vital safety net for millions of coastal residents living in extreme poverty throughout the Indo‑Pacific. By analysing satellite imagery, field surveys, and socioeconomic data from over 200 sites, researchers quantified how these underwater ecosystems help stabilize local fisheries, protect shorelines, and mitigate the impacts of climate‑related hazards.

The research, conducted by an international team of ecologists and economists, found that communities adjacent to healthy seagrass beds reported higher fish catch rates and lower income volatility than those in areas where seagrass had been degraded. The study also linked intact seagrass habitats to reduced erosion and storm damage, translating into lower disaster‑relief costs for vulnerable populations. These findings provide the first empirical evidence at this scale that preserving seagrass can directly support the livelihoods of people living in the lowest income brackets.

Policy makers and conservation groups can use the results to advocate for stronger protection and restoration of seagrass ecosystems. By recognising the economic and social benefits highlighted in the study, governments across the Indo‑Pacific may be better positioned to integrate seagrass conservation into broader strategies for poverty alleviation and climate resilience.
