Agricultural Productivity of Selected Philippine Crops: Effect of Climate Change in Cotabato Province

This study focused on the effect of climate change on agricultural productivity. The purpose of the study was to determine the rainfall pattern in North Cotabato from 2006 to 2020, the trend of minimum and maximum temperatures in North Cotabato from 2006 to 2020, the relationship between rainfall, temperature, and crop yield, and the effects of rainfall and temperature on crop yield. Rainfall, temperature and crops (rice, corn, pineapple, banana and coconut) data were obtained for a period of 15 years from Department of Science and Technology- Philippine Atmospheric, Geophysical and Astronomical Services Administration (DOST-PAGASA) and Philippine Statistics Authority (PSA). Multiple linear regression techniques were used to evaluate the relationship between rainfall, temperatures, and agricultural yield. Maximum temperature has a negative impact on rice and pineapple yield, whereas minimum temperature has a significant impact on all crops, according to the study's findings. With the exception of banana and coconut, rainfall has a negative impact on agricultural output
