Multi-hazard risk assessment for South African maize production . # Repository: Multi-Hazard Risk Assessment for Maize Production in South Africa This repository provides the companion code for the research article: **Assessing Multi-Hazard Risk Dynamics in South African Maize Production: A Framework Integrating Hazard Interactions, Temporal and Spatial Variability, and Irrigation Contexts.** ## **Overview** Climate change amplifies agricultural risks, particularly for **rainfed maize production in South Africa**. This repository contains the scripts used in the study to analyze the **spatio-temporal dynamics of climate-induced hazards**, their interactions, and the role of irrigation in mitigating risks. The study introduces a **multi-hazard risk score system**, integrating: - **City-level clustering** based on irrigation coverage. - **Climatic hazard profiling** (drought, heatwaves, cold spells, excessive rainfall, and disease risk). - **Multi-hazard interaction analysis** linking risk scores to yield variability. - **OLS and Random Forest models** to predict yield based on climatic conditions and hazard interactions. The repository provides all necessary scripts to replicate data preprocessing, clustering, risk assessment, and statistical modeling. ## **Folder Structure** ``` 📂 project_root/ ├── 📂 data/ # Raw and processed data - not included in version control ├── 📂 scripts/ # Python scripts for modeling and analysis (after refactoring) │ ├── 📂 bak/ # Original non-refactored script files ├── 📂 results/ # Output results (plots, model outputs, metrics) - not included in version control │ ├── plots/ │ ├── metrics/ ├── 📜 requirements.txt # Dependencies required to run the code ├── 📜 .gitignore # Ignore large or sensitive files (e.g., data, logs) ├── 📜 README.md # Documentation and instructions for use ``` ## **Installation & Setup** 1.
