Abstract
The present study examines the spatial distribution and level of accessibility of urban green spaces (UGSs) within the context of Mexico City, with a particular focus on their relationship with marginalization. The study examined five distinct categories of UGSs based on their size and subsequently analyzed their total surface area per capita in relation to their correlation with the marginalization index. The data were subjected to descriptive statistical analysis, and correlations were computed to investigate the relationships between variables. We found 1353 UGSs accessible for public use with a total area of 2643 ha. Seventy-four percent of them had <1 ha of surface area, and 51% were located in only three municipalities that were mostly middle- and high-income. These municipalities concentrated a higher area of green spaces per capita. We found a negative correlation between the marginality index and the area of UGSs per municipality; the lower the marginality index was, the higher the area of green spaces. These results suggest that a bad distribution of UGSs can increase environmental injustice since urban environmental services are unequally distributed, affecting particularly marginalized populations. This research is a valuable contribution to the existing body of knowledge regarding the accessibility of UGSs in Mexico City, particularly in connection to marginalized communities. It emphasizes the significance of this topic in the context of environmental justice, urban sustainability, and the formulation of urban policy decisions. By engaging with these concerns, individuals can strive to foster a city that promotes fairness and well-being for all of its residents.

Summary of Main Findings
The research by Ayala‐Azcárraga et al. investigates the distribution of urban green spaces (UGS) in Mexico City and its correlation with social marginalization.
Key findings include:
· A total of 1,353 UGSs were identified, covering 2,643 hectares, with 74% being smaller than 1 hectare.
· 51% of these spaces are concentrated in three municipalities (mostly middle- and high-income), while marginalized municipalities have significantly fewer UGSs.
· A negative correlation was observed between the marginality index and UGS area per municipality, indicating that lower socio-economic areas have less access to green spaces, highlighting a situation of …

Summary of Main Findings
The research by Ayala‐Azcárraga et al. investigates the distribution of urban green spaces (UGS) in Mexico City and its correlation with social marginalization.
Key findings include:
· A total of 1,353 UGSs were identified, covering 2,643 hectares, with 74% being smaller than 1 hectare.
· 51% of these spaces are concentrated in three municipalities (mostly middle- and high-income), while marginalized municipalities have significantly fewer UGSs.
· A negative correlation was observed between the marginality index and UGS area per municipality, indicating that lower socio-economic areas have less access to green spaces, highlighting a situation of environmental injustice.
Generally, this work advances the field by emphasizing the need for urban planning that considers equity in environmental services, advocating for better accessibility and distribution of UGS in marginalized areas. In addition, the inclusion of detailed maps and visual aids had improved the clarity of spatial distribution patterns discussed in the text. Moreover, the findings reveal a clear disparity in green space distribution related to socioeconomic status, which raises ethical concerns about environmental justice.
However, there are still some minor issues related to the overall quality of the work:
· Data Representation: The study indicates that official inventories may misrepresent the actual green space availability and accessibility, undermining urban planning efforts.
· Statistical Analysis Detail: More explanation regarding the statistical methods used for correlation analysis would enhance the robustness of the findings.
Overall, the study underscores the importance of equitable access to urban green spaces in promoting well-being and social justice, making a significant contribution to the discourse on urban sustainability and planning.
