Many indigenous communities in Malaysian Borneo are aware of climate change but do not take collective action to adapt. We suggest that inaction may be due to non-convergent perceptions of climate anomalies within communities. While there is a growing body of evidence suggesting that local perceptions of climate anomalies influence individual climate change adaptation behaviour, several well-documented processes suggest that individuals within indigenous communities are likely to perceive the occurrence and magnitude of climate anomalies differently. How individually different perceptions of climate anomalies translate into the collective is unclear. For the last Four (4) years with Seven (7) remote and rural indigenous communities of Sarawak, we are collaboratively working on exploring the local perceptions of climate anomalies which influence adaptation behaviour of the communities. In addition to developing a pluriverse for traditional and scientific knowledge, we provided internet access and created meaningful technologies such as rain forecast system to access information which will be helpful for developing adaptive capacity of the community members. We also operationalise the Penan forest sign language (Oroo’) as a measure of traditional ecological knowledge (TEK) and find only weak evidence of a systematic statistical association with perceptions of climate anomalies among our sampled respondents. The project is ongoing and in addition to community service, we are creating impactful research by contributing to the academic and scientific body of knowledge.
