Climate change is one of the most crucial and complex challenges of the 21st century, with far-reaching impacts on ecosystems, economies, and societies worldwide. Among the many natural systems affected, forests play a pivotal role, not only as rich biodiversity regions but also as vital carbon sinks that help mitigate the adverse effects of global warming. Recognizing the importance of preserving and managing forest ecosystems, the French-German research initiative AI4Forest is dedicated to exploring how cutting-edge artificial intelligence can be used to better understand, monitor, and respond to the environmental stresses brought about by climate change.
