Drylands are defined as regions where rainfall is low relative to the atmosphere's ability to draw water from soil and plants. Expanding boundaries of these regions are frequent concerns in climate change considerations. While they can support large populations and ecosystems, dryland expansion can worsen water scarcity, land degradation and desertification.
