This article details the contributions Indigenous knowledge systems have made to understanding the Earth and the changing times we are living in. For example, the Nunavut women of Canada use knowledge systems and ecological resource management systems in response to the melting Arctic. Meanwhile in the Laramate district of Peru, the organisation Centro de Culturas Indígenas del Perú (CHIRAPAQ) implemented a crop cultivation programme for Indigenous women to improve food security using Indigenous knowledge. In the Yucatán Peninsula of Mexico, Indigenous women used traditional bee-keeping methods to sustainably produce more honey each year. Photo credit: Eskinder Debebe/UN Photo
