Source code for the Global Groundwater Withdrawal (GGW) model

Global Groundwater Withdrawal Model v1.0

Overview

Global Groundwater Withdrawal (GGW) model is a data-driven framework developed to estimate annual groundwater withdrawal (GWW) across three main sectors: domestic, industrial, and agricultural. Implemented in Python, the model operates at a spatial resolution of 0.1° and is used here to estimate annual withdrawal from 2001 to 2020.
