environmental-equity
Environmental equity examines how the distribution of environmental benefits and burdens — such as access to green spaces, clean air, and healthy soils — varies across communities, with a focus on addressing disparities faced by marginalized populations. In plant science, this lens shapes research on urban vegetation, agroecology, and land use by highlighting how systemic inequalities influence which communities benefit from ecosystem services like shade, air purification, and food production. Understanding these dynamics helps researchers and practitioners design more inclusive strategies for urban greening, conservation, and sustainable agriculture.

Researchers used drones to measure air pollution at different heights near elevated highways in Fuzhou, China, finding that traffic-related particulate matter is not evenly distributed — residents (and plants) on certain floors of nearby high-rise buildings face significantly different pollution exposure than those at ground level.
Over 100,000 drone-based 10-second measurements were collected, making this one of the most detailed vertical air-quality profiles ever taken near elevated urban roads.
Elevated road infrastructure redirects airflow in ways that create height-dependent 'hot spots' of particulate matter, challenging the assumption that higher altitude means cleaner air.
The study documents 'vertical environmental inequity' — meaning pollution exposure differs significantly by building floor based purely on proximity to and height of nearby road infrastructure.
