Green cities and vector-borne diseases: emerging concerns and opportunities

Area of Science:

• Urban ecology
• Public health
• Environmental science

Background:

• Nature-based solutions like urban greening are promoted for human well-being.
• Urban green spaces can influence disease vector populations and pathogen transmission.
• Existing evidence on urban greening's impact on vector-borne diseases (VBDs) is limited and often contradictory.

Purpose of the Study:

• To assess the complex relationship between urban greening and vector-borne disease risk.
• To highlight the need for careful evaluation of green space impacts on VBD transmission.
• To inform urban planning and green space management for sustainable VBD risk mitigation.

Main Methods:

• Review of existing scientific literature on urban greening and VBDs.
• Analysis of factors influencing vector populations in urban ecosystems.
• Comparative assessment of findings across different urban landscapes and scales.

Main Results:

• Urban greening has mixed effects on vector populations and VBD transmission.
• Contradictory findings stem from variations in city design, green landscapes, and study scales.
• Understanding these variations is crucial for accurate risk assessment.

Conclusions:

• Urban greening's impact on VBD risk requires nuanced understanding.
• Careful planning and management of urban green spaces are essential.
• Integrated approaches are needed to balance ecological benefits with public health protection.
