Blue spaces, like canals, are central to health policies promoting physical activity (PA), enhancing wellbeing, and addressing inequalities. Alongside the health benefits, they can offer an array of societal, environmental, cultural, and other welfare-enhancing benefits, which shape the overall value of blue spaces for population wellbeing. This study investigated the multifaceted value of canals for promoting physical activity and wider community wellbeing from the perspective of local community members in Birmingham (UK). Two consensus workshops were conducted to identify enablers and barriers to engaging in PA alongside canals. Data were generated using the nominal group technique and analysed quantitatively and qualitatively. The community members shared that connecting with nature, enhancing mental health, and socialising were all key facilitators for using canals for PA. Prominent barriers identified were safety concerns, including anti-social behaviour, inadequate lighting, and fear of visiting alone, as well as a lack of accessibility. Overall, the findings highlight the importance of understanding the community perspective when considering the value of blue spaces, and subsequent investment opportunities. By incorporating the community perspective and embedding a notion of ‘ownership’ over these local assets, this will further enhance the sustainability of investment.

Natural environments, such as inland waterways (IWs), have been identified as a potential means to increase physical activity and promote health and wellbeing. However, further information on predictors of IW usage and their relationship with health and wellbeing outcomes is needed. Data were taken from the cross-sectional UK Waterways Engagement Monitor survey of waterway users (n = 21,537) in 2019/2020. Health outcome measures were life satisfaction, physical activity, and mental wellbeing. Visit frequency was an additional outcome measure. Both bivariate and multivariable associations between outcome measures and features of IWs were explored. The travel-cost method was used to estimate users’ demand, expressed by travel costs to waterways. Multivariable models showed positive associations of frequent visits and use for recreational/leisure purposes with life satisfaction and physical activity. Rural visits were associated with higher life satisfaction than urban ones. Lower visit satisfaction negatively impacted life satisfaction and mental wellbeing. Visit frequency was influenced by individual characteristics and purpose of visit, including visits for exercise. Waterway visits were inversely associated with travel costs (IRR = 0.99, p-value ≤ 0.001), and there was greater demand elasticity for short distances (≤5 miles). Socioeconomic-related inequalities were present. Future policies could enhance frequent use of waterways and alleviate accessibility-related inequalities to improve population health outcomes.
