Research data and code for Separating the Roles of Crop Production Geography and Irrigation Efficiency in Gross Irrigation Withdrawal in China

Description

This release contains the public numerical arrays and Python code supporting the associated manuscript. It includes province–crop-group–year blue-water-footprint, irrigation-efficiency, production, gross-withdrawal and withdrawal-intensity arrays; closed supply and demand margins; conditional gravity/IPF bilateral allocations; annual accounting results; source data for Figures 2–8; and scripts that reproduce the headline values and validate file integrity. The study covers 31 mainland Chinese provincial-level units and two aggregate crop groups during 2000–2018; 1999 irrigation-efficiency values are included only as the lagged reference for 2000. Model-allocated flows are not observed freight movements. The historical calculation workbooks and Tianditu administrative boundary geometry are not distributed.

Steps to reproduce

Download and extract crop_geography_irrigation_withdrawal_data_code_v1.0.0.zip. From the top-level directory, run: python3 code/recompute_headline_results.py, followed by python3 code/validate_release.py. Both scripts use only the Python standard library. The first script reproduces the headline production-geography and irrigation-efficiency results. The second checks row counts, value ranges, route qualifiers, file exclusions, placeholders, local paths, and SHA-256 integrity. See README.md and metadata/variable_dictionary.csv for file roles, variables, and units.
