Ecosystem services through the lens of indigenous people in the highlands of Cordillera Region, Northern Philippines

Understanding the perception, use, and prioritization of ecosystem services (ES) is important for shaping local environmental policies. This study assessed for the Cordillera Region, Philippines, Indigenous peoples (IPs) perception on the significance of ES for their well-being, influence of socio-economic factors attributing to these perceptions, and ranked the most valued ES. Face-to-face interviews were conducted using a semi-structured questionnaires with 922 households in 48 villages of the Region. We found that most frequently identified and valued ES are provisioning (food, income, and medicinal resources) followed by cultural and regulating ES. The study showed signficant influence (p-value 0.001) of ethnicity, occupation, gender, and age to affect local perceptions of ES provided by the landscapes. A remarkable differences appeared in prioritizing ES, e.g. younger local respondents value ES more than older ones; women have appreciated most ES; and ethnic groupings tend to have a different value of ES that are significantly connected with the landscape characteristics. Traditional rice farming systems was ranked as source providing the most valued ES followed by conventional farming systems and off-farming activities like collection of non-timber forest products. Furthermore, IPs involvement to local surveys are useful in ecosystem conservation strategies because the way society modifies an ecosystem is a function associated to perceptions, interest, and values. A relevant information to decision-makers that must be integrated into local development planning to maintain the flow of ES that support the livelihood in a community. •We assessed the Indigenous peoples perceptions (IPs) on ecosystem services (ES).•Socio-economic factors influence IPs perceptions on provisioning and cultural ES e.g. ethnicity, occupation, gender, and age.•Prioritized ES by IPs are associated with their landscape characteristics.•Traditional rice farming systems are appreciated as source of the most valued ES.
