# Urban Heat Islands & Cardiovascular Risk in Sub-Saharan Africa

## Abstract

Synthetic dataset modelling urban heat island effects on cardiovascular health in SSA cities. UHI intensity in African cities ranges 2-6°C above surrounding areas. Combined with rapid urbanization, impervious surfaces, and limited green space, UHI amplifies heat stress and CVD risk, particularly for the elderly and hypertensive.

### Scenarios

- **Megacity Tropical**: Lagos/Kinshasa-type megacities with intense UHI and low AC access.
- **Secondary City Arid**: Sahelian secondary cities with extreme ambient heat plus UHI.
- **Highland Urbanizing**: Rapidly growing highland cities with emerging UHI.

## Parameterization Evidence

| Parameter | Value | Source | Year |
| --- | --- | --- | --- |
| UHI 2-6°C in African cities | Intensity range | Chakraborty & Lee, Nat Commun | 2019 |
| Hypertension 25-35% in urban SSA | CVD risk | Ataklte et al. | 2015 |
| Heat increases CVD mortality 1-3% per °C | Dose-response | Lancet Countdown | 2022 |
