Between 2005 and 2015, megacities globally saw a significant rise in both the proportion of land dedicated to green spaces and the ease with which residents could access them, leading to improved public health. This sustainability research insight is drawn from a 2017 study published in Remote Sensing. Using Quantitative analysis using remote sensing and spatial data., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize the integration and improved access to green spaces in urban design projects, as this directly contributes to improved resident health and well-being.

Key Findings
- 01Mean availability of urban green spaces in the studied megacities increased from 27.63% in 2005 to 31.74% in 2015.
- 02Mean accessibility of urban green spaces increased from 65.76% in 2005 to 72.86% in 2015.
- 03The observed increases in availability and accessibility of urban green spaces are associated with greater health benefits for residents.
Application
Design takeaway
Prioritize the integration and improved access to green spaces in urban design projects, as this directly contributes to improved resident health and well-being.
How to apply
When designing urban environments or retrofitting existing ones, conduct an analysis of current green space availability and accessibility, and propose design interventions that increase both, linking these improvements to potential health benefits.
Project actions
- 01Consider how your design can increase the amount of green space or make existing green spaces more accessible.
- 02Think about the health benefits your design could provide through improved access to nature.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a large sample of 28 megacities.
- +Employs advanced remote sensing technology (Google Earth Engine) for data processing.
Limitations
Measuring actual health benefits directly can be complex and requires extensive data beyond just green space metrics.
Reliability & validity
The study's reliance on satellite imagery and gridded population data provides a consistent and repeatable method (reliability). The use of availability and accessibility as proxies for health benefits is a reasonable approach but might limit the direct validity of health outcome claims.
Think critically
While increased green space is beneficial, consider how factors like the quality, safety, and type of green space might also influence health outcomes, and how these were or were not accounted for in the study.
Design Principles
"Urban green infrastructure is a critical determinant of public health."
This research highlights the direct correlation between urban planning decisions regarding green infrastructure and the well-being of city dwellers. Designers and urban planners can leverage this insight to advocate for and implement strategies that prioritize green spaces, recognizing their tangible health benefits.
What This Means for Your Design
Cities are getting greener and it's easier for people to get to these green areas, which is good for everyone's health.
