Could Nature-based design be the bridge between sustainability and children’s social inclusion? A direct and indirect connection with nature and natural ecosystems is essential for appropriate human development, growth, and general well-being. Different theories emphasize the significance of Biophilia (innate bond with nature) in the early stages of life, as well as Biophilic design in Children’s urban landscapes and the power of playing spaces that reinforce their affinity with the natural environment, their sensory exploration, and the capacity of increasing social interaction. According to the research presented here, children are constrained to indoor environments with a reduced amount of natural resources.
