Human population growth and urbanisation are putting pressure on urban green and blue spaces worldwide. These spaces provide habitat for biodiversity and, as evidence from the Global North shows, can provide health and wellbeing benefits to urban dwellers. Nonetheless, there is a paucity of evidence regarding the wellbeing benefits associated with urban green and blue spaces from the Global South, where the fastest rates of population growth and urban expansion are occurring. Here, we examine green and blue spaces in Georgetown, Guyana, exploring whether frequency and duration of use is (1) associated with nature-relatedness, safety concerns, and sociodemographic characteristics, (2) associated with specific visit motivations (e.g. physical, cognitive, social), and (3) associated with wellbeing (positive and negative experiential, evaluative, eudaimonic, and mental wellbeing). Participants (n = 512) were more likely to visit green and blue spaces if they had higher nature-relatedness, no safety concerns, aged <35 years, and educated above secondary level. Visit frequency was not related to wellbeing. Visit duration did not differentiate according to visit motivations. Visits to green and blue spaces of more than 25 min were associated with increased positive experiential wellbeing. No comparable patterns were found for the other wellbeing dimensions. These findings can inform public health campaigns targeted at specific sociodemographic groups. Moreover, decision-makers could minimise health inequalities by incorporating new green and blue spaces into future development plans (including the provision of backyards), and enhancing existing spaces (e.g. reducing people’s safety concerns). These measures will help maximise wellbeing across all sectors of society.

人口增长和城市化给全球城市的绿色和蓝色空间带来压力。这些空间为生物多样性提供了栖息地，全球北部的证据表明，这些空间可以为城市居民提供健康和福祉。尽管如此，关于全球南方城市绿色和蓝色空间带来的福祉益处的证据很少，那里的人口增长和城市扩张速度最快。在这里，我们研究了圭亚那乔治敦的绿色和蓝色空间，探讨使用的频率和持续时间是否（1）与自然相关性，安全问题和社会人口统计学特征相关，（2）与特定的访问动机（例如身体，认知等）相关，社交），以及（3）与幸福感相关（正面和负面的体验，评估，性和精神健康）。如果参与者（n = 512）具有更高的自然相关性，没有安全问题，年龄小于35岁且受过中学以上教育，则他们更有可能访问绿色和蓝色空间。探访频率与幸福感无关。访问持续时间没有根据访问动机进行区分。对绿色和蓝色空间的访问超过25分钟与增加的积极体验幸福感相关。没有发现其他健康维度的可比模式。这些发现可以为针对特定社会人口群体的公共卫生运动提供信息。此外，决策者可以通过将新的绿色和蓝色空间纳入未来的发展计划（包括提供后院）并增强现有空间（例如，将健康不平等程度最小化）减少人们的安全顾虑）。这些措施将有助于最大程度地提高社会各阶层的福祉。
