A recent study published in Nature Food warns of the detrimental effects of heat stress on livestock productivity in East Africa due to climate change. The research reveals that from 1981 to 2010, livestock have been subjected to increasingly severe heat stress conditions, with expectations of things getting worse. This could potentially render parts of East Africa unsuitable for certain types of livestock production, potentially impacting up to 4-19% of meat and milk production by the end of this century. The study underscores the necessity for immediate action, such as breeding animals that can better tolerate heat and implementing other adaptation strategies. However, the researchers stress that this is only one aspect of the climate change impact on livestock and highlight the need to consider other effects like droughts, floods, and disease spread.
