# Bangladesh Flood PDNA 2022
Research datasets from the 2022 Bangladesh floods, curated by
[Farjana Yesmin](https://farjana-yesmin.github.io) for the paper:
> Yesmin, F. & Akter, R. (2026). *Toward Equitable Recovery: A
> Fairness-Aware AI Framework for Prioritizing Post-Flood Aid in
> Bangladesh.* CCAI 2026 (IEEE). [arXiv:2512.22210](https://arxiv.org/abs/2512.22210)
Part of the [FairHealth](https://github.com/Farjana-Yesmin/fairhealth)
library — `pip install fairhealth`

## Key Findings
The adversarial debiasing model reduces statistical parity difference
by **41.6%** and regional fairness gap by **43.2%** compared to baseline,
with only 2.7 percentage point R² cost (0.784 vs 0.811).
Sunamganj (42.7% poverty, $159.6M damage, 94% inundation) moves from
**rank 14 → rank 6** under the fair model.
