An integrated framework for agricultural drought monitoring in data-scarce regions

The gap

Evidence profile

Sourced from the stated research gap and stated challenges of the source papers, classified as general, spanning 3 journals.

Supporting evidence — 4 representative gaps

• Projected Global Changes in Severe and Extreme Drought Occurrence: A CMIP6 Multi-Model Assessment Using SPI, SPEI, and Concurrent SPI-SPEI Conditions (2026) · Hydrology · doi

  SPI has its limitations since it only considers precipitation in its calculation process and cannot fully reflect the impact of climate warming on drought. The study aims to address this gap by using SPEI, which takes into account the temperature factor and introduces the influence of surface evaporation changes.

• Interannual Variability and Recurring Drought Hotspots in Ethiopia’s South Wollo Highlands (2026) · Hydrology · doi

  There is a need for an integrated framework for agricultural drought monitoring in data-scarce regions. The existing methods have limitations in capturing the complexity of drought dynamics. The study aims to fill this gap by utilizing multisource Earth observation data and various drought indices.

• Spatiotemporal variations in hydrometeorological drought across North Africa and indications of anthropogenic amplification (2026) · Communications Earth & Environment · doi

  Conventional unidimensional approaches to monitoring drought often lead to ineffective planning and management strategies. Traditional univariate monitoring frameworks significantly underestimate the magnitude and persistence of extreme events. The study area is characterized by a pronounced scarcity of ground-based observational data.

• Seasonal ecological quality in China: concurrent and lagged drought responses and dominant factors (2026) · Frontiers in Plant Science · doi

  The study faces challenges in analyzing the complex relationships between ecological quality, drought, and human activities. The research must account for the spatial and temporal variability of ecological quality and drought impacts. The study needs to address the limitations of using remote sensing data and indices such as RSEI and SPEI.
