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 (UoT) and with seed funding from UNDP Innovation Facility. This Phase ‘IoT for Climate Change and Water Management’ focused on testing IoT technology as a real-time microclimate data collection methodology at three small-scale sites. Phase Two was implemented in collaboration with Rwanda Information Society Authority (RISA) with funding from Noreps as ‘IoT for Climate Early Warning and Humanitarian Response.’
