CropSuiteLite is a lightweight, optimized Python implementation of the crop suitability modeling framework presented in the CropSuite paper by Zabel et al. (2025). It is designed to assess how suitable a geographic area is for growing different crops by analyzing climate and soil conditions. This version focuses on performance, scalability, and flexibility, incorporating modern data science libraries and parallel processing to handle large datasets and complex scenarios efficiently. Disclaimer: This repository is an independent implementation based on the concepts, workflow, and structure described in Zabel et al. (2025), "CropSuite: An open modular framework for site-specific crop modeling at global scale." The official CropSuite framework is available from the CropSuite Zenodo repository.
