Habitat Loss andFragmentation

Human development, including urbanization, agricultura, and infrastructure development, is consuming and fragmenting desert habitats at alarming rates. Cities in desert regions are among the fastest- growing urban areas as globally, converting natural desert habitat into developed landscapes. Agricultural expansion, specilarly in areas where groundwater or imported water is acvaiable, transforms desert ecoecosystems intro addisated croplands, eliminating nativa vegestionation anththalse.

Habitat fragmentation isolates populations of desert species, reducing genetic diversity and making populations mole lownable to local extinction.
