Abstract
Objectives
Destruction of agricultural lands and fisheries due to climate-related disasters has implications for food production and food security in Indonesia. We examine how natural disasters affect the economic productivity of fishing and farming households in Indonesia by exploring whether flooding and landslide disasters trigger differing migratory behaviors by the type of farming/fishery operation.
Methods
We assessed farming and fishing households in the 5th Wave of the IFLS survey (2014/2015) adjusting for household survey weighting. Farming and fishing households are described by the presence or absence of migration since the previous IFLS survey (IFLS4: 2007/2008). Next, we further evaluated households by the type of disaster experienced (flooding or landslides) and other characteristics (region, urban/rural, type of operation). Logistic regression models were used to explain the likelihood of migration, assessing effect modification between the type of disaster (flooding or landslide) and type of farm business to better understand their joint influence on migration.
Results
Since IFLS4, approximately 33% of farming households migrated and predominantly moved within the same village or sub-district. Flooding and landslides impacted 8% of households and rice was the most common farm business type (45%). A higher percentage of fishing households were affected by flooding or landslides compared to non-fishing households (23% and 7%, respectively). There were lower odds of migration among rice (OR: 0.75 [95% CI: 0.63,0.89]), corn (0.67 [0.48,0.93]), cassava (0.49 [0.34,0.71]), coffee (0.44 [0.28,0.68]), and cattle (0.49 [0.34,0.70]) farming operations. Migration likelihood was not significantly affected by the joint effect of disaster type and operation type.
Conclusions
Understanding how climate change is impacting agricultural lands and fisheries must coincide with responsive efforts to encourage food production and ensure food security in Indonesia. Our results suggest that farming households may be adapting rather than migrating in response to flooding or landslide disasters. The IFLS provides a tool for examining response efforts of farm and fishing businesses in relation to natural disasters.
