Southern Africa Freight Model / Climate Hazard Exposure

This repository holds processing scripts for an exposure analysis of links in a network model of major freight routes in Southern Africa.

Major steps in the process here:

• process hazard data
• intersect network links to find hazard (exposure) values for each link
• summarise the outputs by each exposed stretch of network link (filtering out zero-exposure stretches)
• summarise the outputs by admin-1 regions (applying a threshold to calculate the total network length exposed to each hazard under each scenario in each region)

Requirements

• Python >=3.8
• Python packages: geopandas pyarrow python-igraph rasterio shapely jupyter notebook
• GDAL command-line tools (gdal_translate, gdal_merge.py)
• GNU parallel
