**Flood & Climate Risk Analytics – Chikwawa District, Malawi**
**## Overview**
This project demonstrates a **flood and climate risk analytics workflow** for **Chikwawa District, Malawi**, conducted at **Traditional Authority (TA) level**.
The analysis integrates flood probability data, administrative boundaries, and population exposure to produce **decision-ready outputs** that support disaster preparedness, response, and planning.
The workflow reflects real-world analytical processes used by disaster management institutions such as the **Department of Disaster Management Affairs (DoDMA)**.

**## Objectives**
* Analyze spatial patterns of flood probability in Chikwawa District
* Assess population exposure to flood risk at TA level
* Classify and rank TAs based on flood impact severity
* Produce SitRep-ready tables and professional maps for operational use
---
**## Data & Methodology**
The analysis combines:
* Flood probability raster data
* Traditional Authority (TA) administrative boundaries
* Population exposure datasets
**Key analytical steps include:**
* Raster sampling and aggregation
* Geospatial joins and TA-level summarization
* Flood risk classification (Extreme, High, Medium)
* Priority ranking to guide response planning
All processing and analysis were conducted using **Python and GIS tools**, ensuring reproducibility and transparency.
