The agricultural sector is one of the more vulnerable sectors to climate change. The Local Government Units (LGUs) in the Philippines have only started incorporating measures into local plans to mitigate or adapt to its adverse effects. The paper examined the farming practices of farmers in San Mateo, Isabela, and how they have adjusted to climate adversities. Primary data was gathered through a survey questionnaire, while focus group discussions and key informant interviews were conducted to verify the findings. Secondary data gathering was done to supplement primary data gaps. The municipality showed high potential for adaptation through farming practices of farmers. Findings show awareness of the adverse effects of climate change, resulting in adjustments in farmers' activities. Dependence on water supply from the Magat River Integrated Irrigation System (MRIIS) affects the farming schedule, as most of the agricultural lands are irrigated, resulting in changes from traditional farming to more updated techniques. The LGU must recognize the need to educate farmers through training and extension education to build farmers' adaptive capacity. The shift in the mindset of farmers makes it easier to introduce new technology, and innovative farming practices already being practiced may be further enhanced through programs and projects of the local government.
