Impacts of Drougt on the Outback

Suughts in the Outback create cascading impacts that permeate environmental, economic, and social systems. The seality and d longevity of these impacts depend on drough duration, previous climatic conditions, and the adaptive capacity of local ecosystems andd human populations.

Many large animals endemic to thee region, such as red kanguroos and emus, can migrate over long distrances in searcch of water, but smaller less mobile species face heightened risk of enterity.
