# Durban Housing Suitability Analysis
Multi-Criteria Analysis (MCA) for evaluating housing suitability in the Mzinyati Stream Catchment, eThekwini Municipality, South Africa.
## Overview
This project integrates spatial data across hazards, infrastructure, socioeconomic factors, environmental conditions, and community input to identify areas suitable for housing development. Weights are derived using the Analytic Hierarchy Process (AHP) with a fuzzy extension (Buckley's method).
**Notebooks:**
- `Durban_MCA.ipynb` — main analysis pipeline (data loading, factor scoring, AHP weighting, suitability mapping, at-risk building analysis)
- `Field_Map.ipynb` — generates a tablet-ready interactive HTML map from the MCA outputs
