Abstract

In recent years, the human influence on the frequency and severity of disaster events has become more evident. Multiple risks, including relative sea-level rise (SLR) and human alterations, are at risk in the tropical delta regions, rendering them increasingly vulnerable to severe flooding, cyclones, storm surges, intrusion of salinity, and other hazards that may also raise magnitudes and frequencies as climate changes. The geographical focus of this chapter is two of the world’s most populated river deltas—the combined Ganges-Brahmaputra-Meghna (GBM) delta in Bangladesh and India, and the Mekong (MK) delta in Vietnam—as these deltas are more vulnerable to climate-induced disasters. In view of the key role of environmental issues in the sustainability of tropical deltas and their broader links to other factors that have an impact on sustainable development like disaster risk governance (DRG), it is important to undertake case-by-case detailed assessments of specific disaster laws and risk management frameworks. This chapter concludes by discussing plausible solutions in the context of sustainable DRG of delta regions in Asia.
