Sunda Strait Tsunami’s Impact on SDGs. A Change in The Welfare of The Tsunami Survivor’s Family

The devastating Sunda Strait Tsunami of December 2018 has had lasting effects on the lives of affected families. The aims of this research are: (1) analyze the long-term recovery of the affected families in terms of poverty status, food security, and family welfare, and (2) analyze the variables within two distinct family groups, namely refugees and non-refugees. This study tracked changes over four intervals post-tsunami to monitor the progress of recovery. A total of 120 families, divided into refugee and non-refugee categories, participated in the study. Within 20 months post-tsunami, family economic downturn only saw a 40 percent recovery from pre-tsunami levels. Initially, there was a rapid increase in poverty status within the first three months post-tsunami, followed by a gradual decline. Despite this, families persisted in employing food coping strategies as an indicator of food security, albeit with decreasing intensity over time. Across three post-tsunami periods, subjective family welfare did not significantly differ between refugee and non-refugee groups, yet refugee families exhibited notably lower objective welfare compared to non-refugee families. This research underscores the pivotal role of family resilience in effectively integrating disaster risk reduction efforts into Sustainable Development Goals (SDGs).
