Desertification profoundly impacts biodiversity by diminishing habitat availability and species richness. As arid conditions spread, many plant and animal species face threats to their survival due to altered ecosystems and reduced resources. Soil degradation leads to loss of native vegetation, which disrupts food webs and decreases population densities. The decline of biodiversity weakens ecosystem resilience, making it harder to recover from disturbances. Addressing desertification is essential for maintaining biodiversity and ensuring that ecosystems continue to provide critical services to both wildlife and humans.
