Assessing the economic value of coral reefs to Solomon Island communities

Coastal communities in Solomon Islands, like many island countries, rely heavily on their coral reef resources for subsistence and income generation. These reefs, similar to others throughout the world are under pressure from human induced impacts and over harvesting. In Solomon Islands, a growing demand for coral for the international aquarium and curio trade, as well as a local demand for betel nut lime (made from live coral) further intensifies stress on the reefs. The collection of coral for these activities can result in the removal of specific coral types, and localised destruction of the reef habitat. This in turn can have major ecological impacts on other reef dependent species like fish and invertebrates. The degradation of the reef can affect the resilience of the whole ecosystem, and its ability to recover from both natural and anthropogenic impacts. A damaged reef system may also lead to negative socio-economic flow-on effects to the communities’ dependant on them.

Community-based resource management and climate change vulnerability assessments in Solomon Islands – Coral Triangle Support Partnership

The warm tropical waters of the Coral Triangle may host the richest diversity of marine life on this planet. More than 75% of all recorded coral species and at least 3,000 fish species and can be found here. A diverse mix of habitats including river estuaries, mangrove forests, seagrass beds and coral reefs sustain this rich marine biodiversity. Resources from this area support livelihoods and provide income and food security for more than 100 million local people, particularly in coastal communities.
 

Ridge to Reef Biodiversity Conservation

Despite the importance of the Philippines’ coastal zone to the country’s national economy, it has not been sustainably managed and faces key challenges arising from habitat deforestation, inter-tidal reclamation, mangrove destruction, river damming, coral removal, destructive fishing methods, over-fishing, the discharge of land-based pollutants and unregulated logging. Over the last 30 years, 70% of mangroves and 20% of sea grasses have been destroyed, while nearly 90% of coral reefs are under threat. All of these factors have led to reduced productivity, diminished livelihoods, increased poverty incidence and a reduction in health quality in the communities that depend on these coastal resources.
 

Knowledge Management within the Coral Triangle

The Coral Triangle is an expanse of ocean covering 5.7 million square kilometers and is considered to be the epicenter of marine life abundance and diversity on the planet. Located along the equator at the confluence of the Western Pacific and Indian Oceans, the boundaries of this region cover all or part of the exclusive economic zones of six countries (CT6): Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands, and Timor-Leste.

Coral reefs are sometimes called the  "Rainforest of the seas" for the astounding array of marine life they harbor. Yet many of the world’s coral reefs are under severe stress, suffering the effects of disease, pollution, overfishing and the growing threat of damage from climate change.
