RESPONSES TO RISING SEA LEVELS2Responses to Rising Sea LevelsEquivocal global warming has continued to cause widespread melting of polar ice and snow thereby increasing the global sea levels (Lister & Muk-Pavic, 2015). For instance, the coastal region south of Vietnam is expected to rise by 30cm by the year 2050 (Reddy, 2017). Such further increase in sea level is anticipated to have far-reaching consequences on nations along coastal regions. As a result, countries have suggested, formulated and implemented policies to mitigate the effects of rising sea levels as follows.Policy OptionsFirst, Smajgl et al. argue that adaptation to sea level rise is necessary. Whereby, a climate changerisk assessment is developed. Adaptation strategies can then be used as critical tools to address the sea-level rise problem (2015, p. 7-12). Subsequently, the Australian government together with countries to the South Pacific region have begun “climate change risk and vulnerability assessments” (Smajgl et al., 2015). The states have emulated options such as abandoning vulnerable areas (migration), setback provisions, and protection. Notably, each of these strategiesrequires a significant capital outlay. Construction of Dikes and EmbankmentsAlso, rising sea levels infiltrate the existing fresh groundwater aquifers and subsequently increase the salinity gradient. As a result, the Vietnamese government has invested in the large-scale construction of dikes and embankments along sluice gates to mitigate salinity intrusion intocoastal agricultural areas. Alternatively, the government has introduced salinity-tolerant crops to alleviate the threat of low production (Reddy, 2017).Reduction in Greenhouse Gas (GHG) Emissions2
