This paper examines the impact of global sea level rise (SLR) on the economic growth, migration, and tourism from various empirical studies and consolidates several sea level projections by 2100 under different scenarios. The paper points out that the regions or countries most vulnerable to SLR include atoll countries and small islands states like Kiribati and Singapore. In addition, it tackles several adaptation cost estimates for selected countries in developing Asia and summarizes adaptive strategies and mitigation as a response to SLR which include retreat, accommodation, and protection. The paper also presents policy recommendations for developing Asia to cope with increasing sea levels.
