Climate change adaptation strategies for coral reef ecosystems

Coral reef in Vanuatu

This paper reports on a dynamic modelling framework for ecosystem-based adaptation planning in a SIDS island context that is focussed on the assessment of coral reef health and resilience under different climate change scenarios, and the consequential economic and human well-being impacts. Port Resolution, Tanna Island was used as a case study to develop, test and model the fringing coral reef, local community and resultant socio-ecological system.

Coastal processes within a coral reef lagoon, Erakor, Vanuatu

Coral reef processes

No data monitoring was done in Erakor Lagoon on Efate, in Vanuatu, to assess current and future risks to the coral reefs. We have led a month data collection in Erakor to improve our knowledge of coastal processes in this area and of wave transformation over the reef.

Predicting sea-level rise induced coastal erosion in Tanna Island

Port Resolution

Anticipated sea level rise in coastal regions is expected to worsen the impact of coastal hazards such as erosion, inundation and flooding from storm surges. Accordingly, the resulting impacts on coastal settlements and infrastructure will be widespread. These impacts are particularly critical in small islands as the settlements and infrastructure are mainly located along coastlines with almost no, or very limited relocation options.

How we protect buildings and communities from sea level rise due to global warming

Sea wall construction in Tanna

Currently, the standard approach to defending buildings and other structures from the rising sea level impacts is through construction of a concrete or rock seawall, or some similar kind of so-called “capital works”. However, these interventions destroy or degrade natural ecosystems. One solution that avoids this problem is to use ecosystems to help reduce the risks from increasing coastal inundation and erosion.
