Cities’ environmental factors are pivotal for the quality of life of the population, and green space is increasingly recognized as a significant environmental factor in this regard. In this analysis, we study the contribution of green space to happiness in a mid-sized city in the Global South. We use a population survey and open satellite imagery to assess the relationship between self-reported happiness and the surrounding greenness of the respondent's place of residence while controlling for age, gender, and socioeconomic status. We measure surrounding greenness using the average NDVI value within different distances from the home address, calculated with open satellite imagery. The results show that age and surrounding greenness are significantly correlated with happiness, while the relationships with gender and socioeconomic status appear to be not significant. Our results indicate that increases of 10% in surrounding greenness at different distances from 100 up to 500 m increase the likelihood of self-reported happiness between 13% and 18%. When quality aspects of green areas are considered, they are also significantly correlated with happiness. This paper contributes to the knowledge of surrounding greenness and subjective well-being in one of the most urbanized regions in the world and promotes the discussion of well-being policies in urban planning. The results indicate that increasing surrounding greenness and its quality in dense urban environments could help to improve the quality of life and well-being of the urban populations in Global South cities like Cali.

城市的环境因素对人们的生活质量至关重要，而绿地越来越被认为是这方面的重要环境因素。在此分析中，我们研究了绿色空间对全球南方一个中等城市幸福感的贡献。我们使用人口调查和公开卫星图像来评估自我报告的幸福感与受访者居住地周围绿色环境之间的关系，同时控制年龄、性别和社会经济地位。我们使用距家庭住址不同距离内的平均 NDVI 值来测量周围的绿化度，该值是通过开放卫星图像计算得出的。结果表明，年龄和周围的绿化程度与幸福感显着相关，而与性别和社会经济地位的关系似乎并不显着。我们的结果表明，在 100 到 500 米的不同距离处，周围绿化度增加 10% 会使自我报告的幸福感的可能性增加 13% 到 18%。当考虑绿地的质量方面时，它们也与幸福感显着相关。本文有助于了解世界上城市化程度最高的地区之一的周边绿化和主观幸福感，并促进城市规划中对幸福感政策的讨论。结果表明，在密集的城市环境中增加周围的绿化度及其质量可以帮助改善像卡利这样的全球南方城市的城市人口的生活质量和福祉。我们的结果表明，在 100 到 500 米的不同距离处，周围绿化度增加 10% 会使自我报告的幸福感的可能性增加 13% 到 18%。当考虑绿地的质量方面时，它们也与幸福感显着相关。本文有助于了解世界上城市化程度最高的地区之一的周边绿化和主观幸福感，并促进城市规划中对幸福感政策的讨论。结果表明，在密集的城市环境中增加周围的绿化度及其质量可以帮助改善像卡利这样的全球南方城市的城市人口的生活质量和福祉。我们的结果表明，在 100 到 500 米的不同距离处，周围绿化度增加 10% 会使自我报告的幸福感的可能性增加 13% 到 18%。当考虑绿地的质量方面时，它们也与幸福感显着相关。本文有助于了解世界上城市化程度最高的地区之一的周边绿化和主观幸福感，并促进城市规划中对幸福感政策的讨论。结果表明，在密集的城市环境中增加周围的绿化度及其质量可以帮助改善像卡利这样的全球南方城市的城市人口的生活质量和福祉。
