Measuring disaster resilience in the Philippines: evidence using network data envelopment analysis

Abstract

In this paper, we assess the resilience of households in responding to climate-induced calamities such as flash floods and landslides in Compostela Valley of the Philippines. Using cross-sectional survey data collected in 2013 and 2014, we applied the integrated data envelopment analysis (DEA)-based network model to estimate a composite resilience score, ranging from zero to one, and decomposed into coping and adaptive capacities. The overall resilience score of households is, on average, 0.75, while the average coping and adaptive capacity scores are 0.61 and 0.92, respectively. The correlation of the overall resilience with the adaptive capacity is significantly higher than that of the overall resilience and the coping capacity. This implies that adaptation measures of households mainly depend on external assistance that enables vulnerable households to recover from calamity, and thus effectively achieve post-event life stabilization. No significant difference in the overall resilience scores is found among villages in the surveyed area.
