Indigenous and local knowledge (ILK) systems are critical for achieving biodiversity conservation, climate change adaptation, and other environmental goals. However, ILK systems around the world are increasingly threatened by multiple stressors. Our study assesses the effect of climate change on ILK held by crop farmers in Peru's Colca Valley. We collected qualitative data on farmers' ILK through semi-structured interviews, which we supplemented with climatological trend analysis in four Colca Valley districts. We found that shifts in the rainy season together with warmer weather affected farmers' ILK, which was less effective for informing crop planting and irrigation practices in the context of climate uncertainty and unpredictability. Changing and uncertain ILK poses obstacles to adaptation strategies that require long-term institution building from local resource users, who may prioritize short-term solutions addressing urgent needs.
