Discussion

Study analyzes aridity index changes and climate trends in Central Kazakhstan, suggesting increased vulnerability to aridification.

Core examination of aridity dynamics reveals a northeast-southwest gradient across Central Kazakhstan.
Statistical analysis indicates northern regions became less arid, improving Aridity Index by +0.007/10 years since 1991.
Seasonal patterns show summer as the harshest with 8% hyper-arid zones and increasing arid lands (69%).
Overall, arid areas expanded from 40% to 47%, indicating significant climate-driven shifts in the region.

Bissenbayeva et al. (2025) studied this question.
