Editing Dryland vegetation cover fraction (section)

== Geographic / System Context ==
Dryland vegetation cover fraction pertains to dryland ecosystems globally, which encompass approximately 40% of the Earth's terrestrial surface. These regions include deserts, grasslands, shrublands, and savannas found across continents such as Africa, Asia, Australia, and the Americas. The geographic context is not limited to specific political or administrative boundaries but is defined by climatic and ecological criteria associated with low precipitation and water scarcity.

Vegetation in these areas is adapted to withstand arid conditions and often exhibits spatial heterogeneity influenced by soil properties, topography, and land use. The distribution and density of vegetation cover in drylands are critical for maintaining ecosystem functions and mitigating environmental stressors such as soil erosion and dust emissions.
