Assessing the drivers shaping global patterns of urban vegetation landscape structure

Area of Science:

• Urban ecology
• Landscape ecology
• Ecosystem services

Background:

• Vegetation is crucial for urban ecosystem functioning and services.
• Global-scale understanding of urban vegetation landscape structure and its drivers is limited.

Purpose of the Study:

• To analyze urban vegetation landscape structure patterns globally.
• To identify demographic, socioeconomic, climatic, and topographic drivers of these patterns.

Main Methods:

• Studied landscape structure in 100 cities worldwide.
• Correlated vegetation patterns with population, GDP, Gini Index, temperature, rainfall, altitude, and topographic variation.

Main Results:

• Vegetation amount, fragmentation, and spatial distribution are key landscape structure descriptors.
• Higher population density correlates with less, more fragmented, and less connected urban vegetation.
• Economically unequal and emergent economies showed more fragmented landscape structures.

Conclusions:

• Urban social systems and climate significantly influence urban landscape patterns.
• Findings offer insights for equitable distribution of ecosystem services and human well-being.
• Supports policy for accessible and inclusive urban green spaces for all inhabitants.
