Summary

GeoCLEWs is a versatile open-source script that offers a wide range of useful features for both developers and users. It is designed to efficiently collect, analyze, and process Global Agro-ecological Zones (GAEZ) data, including high-resolution land and water data, in an automated manner. The original code were rendered non-functional due to its incompatibility with the latest version of the GAEZ v4 dataset. The code has been subject to significant revisions and improvements aimed at increasing its efficiency and ease of use. Leveraging open-source tools and open datasets, the new script is designed to utilize GAEZ v4 datasets to process agro-climatic potential yield, crop water deficit, crop evapotranspiration, precipitation, and land cover.The script streamlines the detailed land and water processing steps required for Climate Land Energy Water systems (CLEWs) modelling.

At the beginning of the script, users are required to provide inputs and customize the setup according to their specific project requirements. Once the necessary inputs are provided, the script will automatically execute the subsequent steps, including the collection of FAOSTAT (Food and Agriculture Organization of the United Nation) and GAEZ data based on the user-provided inputs.

This notebook performs Five main analytical processes:

• Part 1: Initialization and configuration.
• Part 2: FAOSTAT and GAEZ data collection and preparation.
• Part 3: Generating clusters.
• Part 4: Geospatial attributes extraction to clusters.
• Part 5: Calculating key summary statistics generate outputs for further use in CLEWs modelling.
