Hyderabad is running out of breath: City's ventilation crisis sparks concerns over urban planning
The findings have therefore highlighted the urgent need for ventilation-sensitive urban planning to address worsening air quality.
The study, published in the journal Physics and Chemistry of the Earth, analyzed changes in Hyderabad’s land use and ventilation patterns between 1990 and 2020. During this period, the city’s built-up area surged from 13.7 per cent to 51.8 per cent, while poorly ventilated zones increased from 0.7 per cent to 31.6 per cent.
These poorly ventilated areas often coincide with high-density population zones and socio-economically vulnerable communities.
The research points to industrial growth, road density, and inadequate sanitation facilities as significant contributors to ventilation disparities. The northwest and eastern parts of the city, where wind potential is lowest, are among the worst-affected areas.
