Indigenous Peoples hold vast knowledge of the planet and its resources. This knowledge is essential to maintain the healthiest ecosystems on the planet and can support current monitoring efforts. While advances to integrate indigenous knowledge exist, a proper involvement of indigenous peoples in policy and scientific process has to date been limited. Consequently, the precise observations of indigenous peoples remain poorly integrated and overlooked. In this webinar we will present examples of indigenous people’s observations, understandings and ways of managing the natural environment, with focus on components of the hydrological cycle. We will explore further cases that will complement results of our most recent publication and discuss the potential of indigenous knowledge for supporting global water monitoring efforts. The workshop will take place online and the language will be in English. This workshop is organised by GEO AquaWatch, GEO Indigenous Alliance, AquaWatch Australia and the World Water Quality Alliance (WWQA).
