Along with camels, goats are more resilient to drought than cattle. In Southeastern [[Ethiopia]], some of the cattle pastoralists are already switching to goats and camels.

As of 2009, there were 1.2 billion cattle in the world, with around 82% in the [[developing countries]]; the totals only increased since then, with the 2021 figure at 1.53 billion. As of 2020, it was found that in the current Eastern [[Mediterranean]] climate, cattle experience ''mild'' heat stress inside unadapted stalls for nearly half a year (159 days), while ''moderate'' heat stress is felt indoors and outdoors during May, June, July, August, September, and October. Additionally, June and August are the months where cattle are exposed to ''severe'' heat stress outside, which is mitigated to moderate heat stress indoors. Even ''mild'' heat stress can reduce the yield of [[cow milk]]: research in Sweden found that average daily temperatures of {{convert|20-25|C}} reduce daily milk yield per cow by {{convert|200|g|lb|abbr=on}}, with the loss reaching {{convert|540|g|lb|abbr=on}} for {{convert|25-30|C}}.
