Summary

This modelling study addresses the previously under-examined question of how climate change will influence naturally-occurring soil salinization dynamics globally. Using data-driven models, the authors projected soil salinity patterns in drylands through 2100, identifying South America, southern and western Australia, Mexico, southwest United States, and South Africa as salinization hotspots, whilst projecting salinity decreases in the northwest United States, Horn of Africa, Eastern Europe, Turkmenistan, and west Kazakhstan.

Regional applicability

The study is global in scope and does not focus on United Kingdom conditions, where soil salinization is not a major agricultural concern. However, the modelling methodology may inform UK adaptation planning for drylands internationally, and the work contributes to understanding climate-driven changes in soil properties relevant to global food security.

Key measures

Projected changes in soil salinity levels in drylands by 2100 under climate change scenarios; identification of salinization hotspots and areas of projected salinity decrease

Outcomes reported

The study developed data-driven models to predict primary soil salinity dynamics in global drylands through 2100 under projected climate scenarios. It identified geographical regions expected to experience increases or decreases in soil salinization based on climatic change projections.
