Blue forests are coastal ecosystems such as kelp forests, seagrass meadows, salt marshes and mangrove forests. These ecosystems support important nature-based solutions to the climate and environmental crisis – blue forests in Nordic countries alone hold an estimated 33 million tonnes of CO2. Blue forests are also vital for maintaining a sustainable ocean economy. Unfortunately, blue forests across the globe show patterns of decline, including many kelp forests and seagrass meadows in Norway. Further loss of these vital ecosystems will have ripple effects on our economy and well-being. Established in 2014, the Norwegian Blue Forests Network (NBFN) aims to jointly strengthen the Norwegian competence and know-how in blue forests so that its full potential in addressing the global climate challenge and provisioning of other ecosystem services can be met nationally and internationally.
