This citizen science project empowers Indigenous women from the Pueblo Pastos in Colombia to lead climate research. Thanks to a web app, Indigenous women become frontline researchers and gather critical gender and climate evidence, addressing the data gap on this nexus. Collaborating with Indigenous women’s organizations in Colombia, WOMER equipped 23 young women leaders with digital tools, high-quality methodologies, and skills to collect, analyze, and use data from their territories. They built a comprehensive repository and created 33 indicators to guide gender-responsive climate policies.
