Peri-urban areas, characterized by their blend of urban and rural features, are located at the rural–urban fringe, the transitional zone where urban and rural landscapes meet. These areas are often overlooked in traditional planning. These regions are under pressure from urban sprawl, industrial pollution, and complex land-use conflicts. SpurUP (Sustainable Peri-Urban framework for Climate Neutral development) is a Horizon Europe initiative designed to give peri-urban areas a clear voice and a sustainable future.
