Funded by the EU Horizon Europe Programme, Trees4Adapt is a €4 million, 4-year project that aims to tackle the complex risks of climate change and biodiversity loss by supporting the design and implementation of tree-based solutions across Europe. Through transdisciplinary research, modelling, and stakeholder engagement, the project will provide decision-makers with the knowledge and tools needed to build climate resilience, restore biodiversity, and avoid maladaptation.
