Aridness -

: Some plants utilize high calcium levels to strengthen cell walls against desiccation or high salt concentrations to reduce water loss through transpiration.

: Arid zones now cover approximately 40.6% of the world's land area (excluding Antarctica). This is a significant increase from 37.5% just 30 years ago.

: Larger organisms (macrofauna) are often more adapted to aridity than microbes, acting as the primary recyclers in hot, moisture-deprived habitats. The Urban Challenge

: Experts argue that arid cities must move away from 1950s design paradigms to prioritize shade, walkability, and technological innovation to remain viable. The "Aridification" of the West

This report explores the concept of —long-term climatic dryness—as a silent but powerful force reshaping the planet's landscapes and societies. The Global State of Aridity

Surprisingly, arid areas are not biological wastelands; they often harbor diversity rivaling jungles.
