Quantifying climate change driven environmental losses in coastal areas: a practical framework

Climate change may exacerbate the environmental damage due to coastal hazards. Quantifying the potential magnitude of the climate change impacts on coastal wetlands and associated Coastal Ecosystems Services (CES) has always been a challenge for economists and ecologists, and therefore remains a significant knowledge gap. This is especially the case in data-scarce developing countries that are likely to suffer the most form climate change as their adaptive capacity to impacts is low.
The study presented here was undertaken to develop and formulate a practical framework to quantify climate change driven Environmental Losses (QuantiCEL) that adopts a novel scenario-based approach, grounded in economic valuation techniques, secondary data and expert opinions.
Applying the QuantiCEL framework to three developing countries (i.e. Indonesia, Bangladesh and Sri Lanka) shows that, where the absolute loss value of CES by the end of the 21st century is concerned, food provision and tourism are the CES with higher loss values. However, art, amenity, and tourism are the highly affected CES where the percentage loss (by the end of the 21st century) relative to the present-day value of CES is concerned.
