The latest round of monitoring shows around 23% of New Caledonian reefs are deteriorating due to climate change, which is causing heat stress and more frequent and severe weather events such as cyclones which damage reefs. In addition to these global pressures, soil erosion and over-fishing are significantly impacting the health of local reefs. Determined to protect their precious marine ecosystems, local reef managers and coastal communities have joined a global initiative to help their reefs adapt.
