This study aimed to look into gender role and climate change mitigation practices and their implications among the B’laan tribe in Mudan, Sarangani Province. This study used both the quantitative and qualitative methods in analyzing the data. Percentage was used in assessing socio-demographic characteristics of the respondents. Qualitative methodologies were key informants interview, informal discussion and direct observation. A total of 80 respondents were included in the study chosen through purposive sampling. Majority of the respondents are female, 36-45 years old, with 6-10 members of the family whose income ranges from 1,000.00-5,000.00php and whose main source of family income is farming. The household basically is the domain of the woman while the man takes care of the food production. Climate change has greatly affected agriculture where B’laansis largely dependent on especially during dry season. In times like this, the woman is forced to involve in income-generating activities, worse, sometimes she has to leave her home and children to the care of her husband and seek employment as house-helper. This has drastically brought about changes in gender role. When this happens, decision-making which traditionally resides on man now is transferred to the woman.
