摘要

The coastal zones are highly susceptible to the impacts of natural hazards. The topographic characteristics, societal features, and economic status define the extent of risk and exposure in a location. India has a longer coastline, and a higher percentage of the population resides in the coastal zones, which exacerbates the vulnerability to natural hazards. This chapter concisely reports various natural hazards occurring over the coastal zones, mainly emphasizing the coastal states of India. Besides, the impacts of such natural hazards are deliberated under the future climate scenarios, and the relevant contributors defining the regional risk. The eastern coastal states are revealed to be highly hazardous to the effects of tropical cyclone strikes and associated storm surge events that can lead to coastal flooding. On the other hand, the western coastal states, bounded by the Western Ghats, are severely prone to landslides and frequent severe flooding due to extreme rainfall events. The increased rate of sea-level rise and the rapid warming of the northern Indian Ocean might accelerate the risk of coastal zones to frequent and intensified tropical cyclone hazards in the future. Also, rapid urbanization, weak economic status, and higher population density further increases the possible exposure of coastal zones to risks. The comprehensive deliberations encompassed in this chapter could aid in framing disaster management strategies to mitigate the risks and enhance resilience.
