The 4-year project (2023-2027) ‘OPTimising FORest management decisions for a low-carbon, climate resilient future in Europe’ (OptFor-EU) will support EU forests in their capacity to mitigate and adapt to climate change. How? From science to practice, with a user-centred Decision Support System (DSS) assisting decision-making in 8 case studies. 16 partners from 9 countries will work together on management practices, ecosystem service provision and CO2 sink provided by forests, enhancing forest resilience and its capacities to mitigate climate change.
