Structural heat adaptation and education in urban settings (SHAPES trial): study protocol for a cluster randomised...

Area of Science:

• Environmental Health
• Climate Change Adaptation
• Urban Planning

Background:

• Extreme heat events are increasing globally due to climate change.
• Urban heat island effect exacerbates heat risks in cities, particularly in the Global South.
• This study addresses the urgent need for effective heat adaptation strategies in vulnerable urban populations.

Purpose of the Study:

• To evaluate the effectiveness of the resilience and heat adaptation bundle (ReHAB) in reducing heat-related morbidity and mortality.
• To assess the impact of ReHAB on indoor ambient conditions in urban settings.
• To provide evidence-based recommendations for urban heat adaptation policies, especially for the Global South.

Main Methods:

• A cluster randomized controlled trial involving 22 clusters in Pakistan.
• Intervention group receives the ReHAB bundle: community education, reflective paints, shading, improved ventilation, and community shaded spaces.
• Data collection via wearable devices, household surveys, and environmental sensors for health, behavior, and thermal conditions.

Main Results:

• The study is ongoing; results are pending.
• Anticipated outcomes include improved indoor thermal comfort and reduced heat-related health issues.
• Expected to demonstrate the ReHAB bundle's efficacy in mitigating urban heat impacts.

Conclusions:

• Findings will inform policy for urban heat adaptation in the Global South.
• Evidence generated will support the implementation of integrated heat resilience strategies.
• The study aims to enhance the adaptive capacity of urban communities to extreme heat.
