Summary
By reconstructing schoolyards with greenery, physical activity levels among children can be increased at the population level and also mitigate health and environmental risks resulting from rising climate changes in urban areas. The overarching purpose of the proposed project is to: i. increase physical activity levels among school-aged children, independent of socioeconomic factors, and thus affect short- and long-term health outcomes on a population level ii. establish an evidence-based bottom-up approach for schoolyard reconstructions iii. evaluate the cost-effectiveness of schoolyard reconstructions with greening on health outcomes and its environmental impact

Interventions
The current study will be designed as a quasi-experimental stepped-wedge intervention where schools undertaking schoolyard reconstruction will act as both control and intervention schools. By using the stepped-wedge study design, with internal control schools, will enable the control for the seasonal variation in children's physical activity levels and for the age-related decline in physical activity throughout childhood. That is, without control schools we would be unable to attribute a change in physical activity to the reconstruction of the schoolyards - as any difference in physical activity before and after the schoolyard reconstruction in the intervention group could be explained by the natural change in physical activity over time.
