- Future global water scarcity partially moderated by vegetation responses to rising CO 2 (2026) · Hydrology and Earth System Sciences · doi
Most studies of future water scarcity rely on hydrological models that neglect vegetation responses to rising CO2. There is a need to investigate the influence of vegetation responses on water scarcity projections. The impact of CO2-induced stomatal and structural responses on the water cycle is not well represented in current hydrological models.

Although the effects of water stress on vegetation productivity and the underlying ecological mechanism have been recognized extensively, the relative contribution of atmospheric and soil water stress changes on vegetation productivity are still in debate, and their temporal dynamics remain unclear.

Because climate change is predicted to markedly alter current hydroclimatic conditions later this century, a better hydrological indicator of ecosystem performance is warranted to improve understanding of hydrological controls on vegetation and to predict changes in the future.

The response mechanisms and driving processes of water use efficiency are not well understood. There is a need to study the spatiotemporal variation of water use efficiency and its responses to climate change. The impact of the Returned Farmland to Forestry and Grassland Project on water use efficiency is not well understood.
