Crucial for biodiversity, coastal protection, and local livelihoods.

According to the US National Oceanic and Atmospheric Administration, about 71 percent of the Earth’s surface is covered by water. However, coral reefs occupy only around 0.1 percent of the ocean area. Despite this small footprint, coral reefs support roughly 25 percent of all marine species and provide essential benefits to millions of people worldwide.

Papua New Guinea (PNG) lies within the Coral Triangle, a region that includes Indonesia, Malaysia, the Philippines, Timor-Leste, the Solomon Islands, and PNG itself. This area is recognized as the global centre of marine biodiversity, containing the majority of the world’s coral species and a significant proportion of reef fish species. Many Papua New Guineans live along the coast and depend on coral reefs and lagoon systems for protein, income, and protection from coastal hazards such as king tides and storm surges.

However, coral reefs in PNG face growing threats from rising ocean temperatures that cause coral bleaching, overfishing, destructive fishing methods such as dynamite fishing, coral harvesting for jewellery and aquariums, pollution, and unsustainable coastal development. It is estimated that up to 90 percent of reefs in the Coral Triangle are under threat from these combined pressures. The loss of coral reefs would destroy habitats for about a quarter of marine life, reduce fish stocks critical for food security, and diminish natural coastal protection.

In response, the six Coral Triangle countries launched the Coral Triangle Initiative on Coral Reefs, Fisheries, and Food Security, aiming to sustain marine resources and conserve biodiversity. PNG also runs local programs like Hiri Coral PNG and the Sea Women of Melanesia, focusing on coral farming and community conservation. However, these initiatives face challenges such as limited funding. 

With PNG’s vital role in the Coral Triangle, are responsible authorities doing enough to implement effective and sustainable measures to protect and restore marine life, especially coral reefs, amid growing environmental threats? What more can be done to strengthen these efforts and secure the future of PNG’s coastal communities and marine ecosystems?
