Abstract
Aggravated climate conditions affect the Philippines adversely due to its vulnerability to the impacts of climate change. This study sought to determine climate change's economic impacts on the Philippines' marine fisheries. Using the net effect of the climate variables, the impact of climate indicators atmospheric temperature, sea surface temperature, chlorophyll-a concentration, and precipitation on Bali Sardinella were measured across the fish landing data across ten fishing grounds from 2005 to 2020.
A correlation analysis was employed to determine the climate variables that affect the pelagic fish and the linear association between the harvest and SST, a significant driver of climate change on pelagic fish. Similarly, a panel data analysis was done using a Fixed-Effects Model with Driscoll-Kraay Standard Errors to determine the impact of climate change on Bali Sardinella. The net effect of the coefficients was then used to determine the change in harvest, and the prevailing average price for April 2022 was used to identify the value of the loss.
Results showed that the variables atmospheric temperature, SST, precipitation, chlorophyll-a anomalies, policy, and the number of commercial vessels were significantly affecting the harvest of Bali Sardinella. As such, the maximum threshold of atmospheric temperature and SST anomalies relative to 2003 is 0.73°C and 0.43°C, respectively. Also, the average loss in the harvest across the fishing grounds due to climate variables is 204.46 metric tons, equivalent to Php 20,446,134.86, while the aggregate among the fishing grounds has led to a loss of 2,048.884 metric tons with a value of Php 204,888,395.93.
