Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1275This study specifically analyzed the indigenous watershed management practices of the Kankana-ey community residing in the municipalities of Alilem, Sugpon, and Suyo in Ilocos Sur, within the Lower Amburayan Watershed. It aims to document and analyze how traditional ecological knowledge such as planting native trees, harvesting rainwater, and maintaining rivers and streams contributes to the preservation of wate resources and the promotion of sustainable environmental stewardship amid modern environmental challenges like deforestation, pollution, and climate change. Despite the growing recognition of indigenous knowledge in environmental conservation, there remains a lack of localized research focusing on how specific communities like the Kankana-ey manage watershed ecosystems. This research gap limits the incorporation of their practices into formal watershed management frameworks. The study determined the socio-demographic profile of the respondents, identified traditional watershed management practices, analyzed their effectiveness, and assessed the challenges faced by the Kankana-ey community in managing the watershed. Data were collected through surveys, direct interviews, and observations within the three municipalities. Findings revealed that the majority of respondents are male laborers, and that maintaining rivers and streams is the most commonly practiced and highly effective indigenous watershed management method. Climate change emerged as the primary challenge in sustaining these practices. The results underscore the Kankana-ey community’s vital role in preserving water resources and promoting sustainable practices. The research highlights the importance of incorporating indigenous knowledge into wider environmental policies to enhance watershed conservation efforts and promote the health of indigenous communities.Thesis
