Students are familiarised with the concept of social and environmental justice through the story, photos, and videos of Birdy bird Travel – a bird who likes travelling through Croatia and Serbia. Via web 2.0 apps (Linoit, WordArt) students analyse Birdy’s “environmental” photos in order to build a socio-environmental fair neighbourhood (water/lake/sea) in which they would like to live using recycled materials. But before the building commences, they have to discuss and collaborate with their classmates in order to understand the principles and importance of nature-based solutions (NBS). Nature-based solutions must benefit biodiversity and support the delivery of a range of ecosystem services.
