Water availability regulates abrupt shifts in global terrestrial vegetation productivity by reducing resilience

Abrupt shifts in vegetation productivity induced by environmental change profoundly affect ecosystem functions and services, such as carbon sequestration, biodiversity maintenance, and climate regulation, yet their long-term global patterns and underlying drivers remain insufficiently understood. In this study, abrupt shifts in vegetation productivity were identified using two independent long-term satellite datasets, and early warning signals were assessed through ecosystem resilience. The main drivers of resilience decline were further examined across land cover, climate, and human-activity dimensions. The results showed that negative abrupt shifts were predominantly concentrated in high northern latitudes and equatorial regions, and that both negative and positive abrupt shifts displayed distinct increasing trends after 2002. A sharp decline in ecosystem resilience was also detected during the four years preceding abrupt shifts.

The dataset contains all of the original data, as well as all of the data and code for the graphs that produced the main text.

## Description of the data and file structure

The data processing and plotting are done using NCL (NCAR Command Language, [https://www.ncl.ucar.edu/](https://www.ncl.ucar.edu/)) and R ([https://www.r-project.org/](https://www.r-project.org/)), with NCL being the primary tool and R serving as a supplementary tool.

The missing value for all data is -32767.0.
