Economics of coastal zone : adaptation to climate change (English)

This report explores the answer to a difficult question: what are the potential costs for coastal adaptation from 2010 until 2050 in response to human-induced climate change? The work reported here builds on the earlier estimate of the United Nations Framework Convention on Climate Change (Nicholls 2007) of incremental protection costs in 2030. While these have been improved in a number of aspects, the results remain a preliminary first estimate of the possible adaptation needs and they show that significant further analysis of the topic is necessary. In terms of climate change, sea-level rise is the climate driver that is analyzed; the possibility of enhanced storm impacts due to higher water levels in areas subject to tropical storms and cyclones is also considered as a sensitivity analysis with the high sea-level-rise scenario. The analysis uses the framework of the Dynamic Interactive Vulnerability Assessment (DIVA) model to explore the costs of three main protection responses to climate change: sea and river dike construction and maintenance costs; beach nourishment; and port upgrade. These global studies need to be reinforced by national case studies to better understand how adaptation might operate on the ground, including the relationship with wider coastal management and non-climate-change issues.
