Natural experiments in urban air quality in Rwanda

To understand the current drivers of air pollution, we used two natural experiments (Car-Free Day and COVID-19 Lockdown) to examine their impact on air pollution using particulate matter air pollution data in Kigali City. The health impact of non-motorized transport events in Kigali, known as ‘Car-Free Days,’ goes beyond just mass physical exercise. Importantly, it has reduced air pollution by 15%, this is expected to save more than 200 disability-adjusted life years annually.

Bio-reconciliation: Dialectics for healthier, equitable urban futures – Biophilia and Biophobia

I diagnose urbanization’s toll: 60% of city dwellers face stress-related morbidity, which biophilic design aims to curb; yet my 100-study review reveals biophobia’s backlash, like glare spiking cortisol 10%. This dialectic, rooted in evolutionary and urban disconnect, exacerbates health inequities e.g., 30% higher stress in underserved areas —demanding my evidence-based, Hegelian synthesis to recalibrate architecture for resilience.

Where do older people in China want to live as they grow old?

The image of older people in China preferring to live with their children is not uniformly the case, particularly for those with the most resources, and with fewest. Not enough is known about preferences for what kinds of places older Chinese want to live in, including the design, location, and tenure of homes.
