This book foregrounds socioecological stewardship in urban spaces. It demonstrates how activities like gardening and participating in events that spark ecological learning foster a sense of place, social connections, and lively neighbourhoods. Offering case studies from Sydney, Australia, it presents an innovative, interdisciplinary, place-based design research methodology. This approach combines ethnography to examine people-place-environment relationships with design's potential for creating change through artefacts and initiatives like maps, curated walks, and workshops. The book contributes to methodological debates by showcasing how visual communication and socially engaged practices strengthen ethnographic understandings of society, culture, and the environment. The authors show that these practices connect everyday environmental actions to broader contexts, such as making cities liveable during climate change, aligning with the United Nations' Sustainable Development Goal 11: Sustainable Cities and Communities. Neighbourhood Ecologies offers key insights for scholars and students of urban sociology, human geography, anthropology, design studies, and social movement studies interested in how critical environmental issues become grounded in local contexts.
