ORANJESTAD (AAN) – Study Finds Aruba Lost Over 20% of Coral Reefs in 20 Years, according to research highlighted by Christie Mettes of the Metabolic Foundation, who emphasized the critical role coral reefs play in protecting Aruba’s coastline and supporting the island’s tourism and marine ecosystems.
Speaking in an interview, Mettes explained that coral reefs act as a natural barrier against the effects of climate change by helping protect Aruba’s coastline from rising sea levels, storm surges, and powerful waves generated during tropical storms and hurricanes.
Metabolic Foundation conducted a study in 2022 comparing the condition of Aruba’s coral reefs between 2002 and 2022. The findings showed that more than 20% of the island’s coral reefs disappeared during the two-decade period. To obtain a more current picture of reef health, the foundation later analyzed satellite data to monitor recent changes across Aruba’s marine ecosystem.
According to the research, several reef systems—particularly those located near the harbour area and San Nicolas—continue to deteriorate. The coral formation at Indian Head has also been shrinking at a relatively rapid pace.
Despite these concerns, Mettes noted that the research also identified encouraging signs of recovery. Coral reefs around Isla di Oro recorded consistent growth during the 2002–2022 study period, and that positive trend has continued between 2022 and 2026, with two additional nearby reef systems also showing improvement.
Mettes said these findings demonstrate that coral reefs can recover when environmental conditions are favorable. He explained that adequate space, limited human disturbance, good water quality, and healthy connections with nearby mangrove ecosystems are all essential for maintaining resilient marine habitats.
Beyond protecting the coastline, coral reefs support fisheries, generate the white sand beaches that are central to Aruba’s tourism industry, and provide significant ecological, cultural, and economic value.
Mettes concluded that protecting and restoring Aruba’s coral reefs remains essential for preserving the island’s natural environment and ensuring that future generations continue to benefit from healthy coastal ecosystems.
