Supporting evidence — 8 representative gaps

• Integrated drought assessment in Morocco: a combined approach using meteorological, hydrological, and remote sensing observations (1975–2023) (2026) · Modeling Earth Systems and Environment · cited 1× · doi

  Future research should explore the coupling between biophysical indicators and socio- economic vulnerabilities, integrate additional ecological parameters, such as soil moisture and evapotranspiration, and incorporate lagged correlation analyses at monthly or seasonal scales to better capture the temporal dynamics of vegetation response to hydrometeorological drought.

• Compound atmospheric and soil droughts amplify the global loss of vegetation productivity (2026) · Communications Earth & Environment · doi

  Atmospheric droughts (high vapor-pressure deficit, VPD), soil droughts (low soil moisture, SM), and their compound occurrence (compound droughts, CDs) impose varying stress on terrestrial vegetation, yet their relative global impacts on productivity remain poorly quantified.

• Regime-based drought dynamics: a data-driven differential equation framework for state transitions, weak seasonality, and irregular variability (2026) · Natural Hazards · doi

  Traditional analyses have largely relied on deterministic indices or stochastic time-series models, but these assumptions often oversimplify reality. Emerging evidence suggests that drought is characterized by nonlinear evolution, regime-like behavior, and irregular variability, which challenges classical monitoring and prediction systems.

• GRACE satellite observed hydrological controls on interannual and seasonal variability in surface greenness over mainland Australia (2014) · Journal of Geophysical Research Biogeosciences · cited 139× · doi

  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.

• Extreme precipitation patterns and reductions of terrestrial ecosystem production across biomes (2012) · Journal of Geophysical Research Biogeosciences · cited 89× · doi

  Precipitation regimes are predicted to shift to more extreme patterns that are characterized by more heavy rainfall events and longer dry intervals, yet their ecological impacts on vegetation production remain uncertain across biomes in natural climatic conditions.

• Compound droughts slow down the greening of the Earth (2023) · Global Change Biology · doi

  Abstract Vegetation response to soil and atmospheric drought has raised extensively controversy, however, the relative contributions of soil drought, atmospheric drought, and their compound droughts on global vegetation growth remain unclear.

• Improved model predictions of carbon and water fluxes by including drought legacy effects (2026) · Biogeosciences · doi

  Future studies should investigate the impacts of drought legacy effects on ecosystem function in different biomes and climates. Future research should seek to improve the representation of drought legacy effects in land surface models. The study's findings highlight the need for more accurate modeling of drought legacy effects to inform decision-making.
