Considering the pressing challenge of climate-related risks in Rwanda and in the region as well as the need for more accurate climate and weather data and information, Meteo Rwanda and UNDP piloted the project ‘Internet of Things (IoT) for Climate Early Warning’. The pilot project consisted of two phases. Phase One was implemented in collaboration with University of Tokyo and with seed funding from UNDP Innovation Facility. This Phase ‘IoT for Climate Change and Water Management’ focused to test a new real-time microclimate data collection methodology using IoT technology in three small-scale sites. Phase Two was implemented in collaboration with RISA and funding from Noreps as ‘IoT for Climate Early Warning and Humanitarian Response’.
