The COFA project aims to develop an innovative framework for post-mining land reclamation, merging environmental restoration with sustainable agricultural practices. COFA focuses on converting degraded land into productive agricultural spaces, promoting both ecological and socio-economic growth. Central to this effort is the Agricultural Toolkit, a comprehensive online resource offering tools such as a geospatial database, carbon farming and energy crop calculators, and practical guides for land reclamation. The toolkit will assist stakeholders in making informed decisions on transforming post-mining areas into carbon-sequestering agricultural lands. The project focuses on three key regions: Most Basin (Czech Republic), Western Macedonia (Greece), and Sieniawa (Poland), developing tailored reclamation scenarios for each. Led by a multidisciplinary consortium of six partners from three European countries, COFA will support coal-transitioning regions by fostering sustainable land use, engaging stakeholders through workshops, and contributing to climate change mitigation efforts.
