Theory-based design for promoting positive behaviours in an urban blue space: Pre-and-post observations of a community co-created intervention in Plymouth, United Kingdom

Behaviour observation and mapping are useful planning tools to generate evidence create people-friendly public spaces. Small-scale interventions gaining popularity as cost-effective quick solutions regenerate degraded urban outdoor environments. Onsite behaviour with GIS underpins gathering, analysis, design decision-making. Using the BlueHealth Assessment Tool (BBAT) developed within EU-funded Horizon 2020 Project “Blue Health”, we carried out pre- post- intervention observations of visits, activities visitors' characteristics in a site at Teats Hill, Plymouth, United Kingdom. Pre-post comparison visits three target areas entire before within-site area (a small open-air theatre) rest afterwards were examined analyse impact on socialising relaxing activities. data was both spatially statistically analysed. Key outcomes sitting, standing, walking, activity dog, viewing, using phone socialising. Both logistic regression model spatial analysis density maps hot spot confirmed an increased use theatre its positive park (the non-intervention area). Our logit models showed that promoted for health (i.e. blue space activities, socialisation, activities), greater inclusivity diversity visitors. We conclude evidence-based approach can increase accessibility, improve place affordances promote psychological well-being benefitting local communities.
