Building JONAM: Using Copernicus Earth Observation Data to Help Restore Lake Victoria's Fisheries
Rather than building another dashboard, we wanted to solve a real problem affecting millions of people around Lake Victoria: declining fish stocks caused by worsening water quality. Lake Victoria supports millions of people through fishing, transportation, agriculture, and tourism. However, over the years the lake has experienced: Increasing water pollution Poor water quality Frequent algal blooms Reduced fish breeding habitats Declining fish populations For fishing communities, these are not just environmental issues—they directly affect livelihoods, food security, and local economies.
