Impact of Community Cleanups
Rigorous measurement of environmental and social outcomes of organised cleanup activities — combining waste data, biodiversity indicators and community wellbeing metrics at local and global scale.
Environmental Behaviour Change
Longitudinal research on how participation in cleanup initiatives affects long-term environmental attitudes, pro-environmental behaviour and ecological identity formation in diverse community contexts.
Mechanisms of Societal Mobilisation
Studying the organisational, communicative and motivational mechanics of large-scale citizen mobilisation through the World Cleanup Day movement — including cross-cultural and cross-national comparative analyses.
Civic Participation Models
Models of civic engagement and their transferability: how environmental participation translates into broader civic competence, collective efficacy and democratic participation across different political and cultural contexts.
Citizen Science Integration
Development of data collection protocols enabling participants to contribute scientifically valid waste composition, litter density and ecological condition data during cleanup events.
Policy & Systemic Leverage
Translating findings into evidence-based policy recommendations for municipalities, NGOs and supra-national bodies on maximising the environmental and social co-benefits of community action programmes.
Research Design & Methods
Cluster 4.1 employs a mixed-methods approach: standardised survey instruments (n > 10,000 participants), geospatial waste mapping, longitudinal panel studies, and ethnographic fieldwork within cleanup communities. Statistical analysis follows guidelines of the American Psychological Association and the European Social Survey.
