But concentrations of grazing animals used for human consumption across the world have been shifting for the last 25 years, according to a new study, suggesting profound environmental and climate consequences.<\/p>\n<p>In a paper published today in the Proceedings of the National Academy of Sciences, authors from Arizona State University used data from the Food and Agriculture Organization of the United Nations to establish livestock trends from 1999 to 2023. In middle Africa, parts of Asia and Central and South America, livestock numbers are on the rise, while in North America, Europe and Australia their numbers are falling.\u00a0<\/p>\n<p>But the environmental changes associated with a decrease in livestock on the land have not always been studied at the same rate as the impacts of an increase in stocking on a landscape. From 1999 to 2023, there were about 10 papers published on overgrazing, the ecological impact of species like cattle eating the same patch of land too frequently, for every one study exploring how landscapes respond in the absence of livestock, said Osvaldo Sala, director of Arizona State University\u2019s Global Drylands Center and one of the paper\u2019s authors.<\/p>\n<p>As a result, scientists do not understand the ecological consequences of decreasing livestock as well as they understand overgrazing\u2019s impacts.<\/p>\n<p>\u201cThe mismatch between the patterns of stocking rates and the literature really surprised me,\u201d Sala said. \u201cPolicy is determined by what scientists tell the broader community, so if the scientists are [saying] that the major problem is overgrazing, the policy will be to try to study overgrazing, combat overgrazing, while, in fact, that only addresses the challenges in half of the world.\u201d<\/p>\n<p>Increasing concentrations of livestock were driven by factors like regional changes in total meat consumption and the amount of poultry or pork production, and correlated with wealth and population growth.<\/p>\n<p>Fewer livestock in North America and elsewhere in the West brings difficult-to-predict environmental consequences. Sometimes ecosystems can rebound in the absence of cattle, restoring biodiversity, but this is not guaranteed. The paper found that decreased grazing can affect local water cycles, increase a landscape\u2019s wildfire risk or reduce biodiversity if regeneration is not properly managed.<\/p>\n<p>These changes can have climate implications\u2014more plant growth traps more carbon, but can make a landscape more likely to burn more severely, releasing carbon stored in vegetation into the atmosphere. Without more research into these outcomes and their relationship to declining stocking rates, scientists may be missing a key component of agriculture\u2019s connection to climate change.<\/p>\n<p>\u201cIt\u2019s not only an opportunity but a need if we want to have a full picture of climate change,\u201d Sala said.<\/p>\n<p>The vast majority of U.S. livestock is in ranges in the American West. Sala emphasized that even though there are fewer cattle on the landscape today than there were in 1999, that doesn\u2019t mean that overgrazing isn\u2019t still an issue.<\/p>\n<p>According to reporting by <a href=\"https:\/\/www.hcn.org\/issues\/57-12\/congress-made-it-easier-to-ignore-grazings-harm-to-public-lands\/\" rel=\"nofollow noopener\" target=\"_blank\">High Country News<\/a>, wealthy landowners in the region allow their cattle to overgraze rangeland despite warnings from federal agencies.\u00a0<\/p>\n<p>\u201cThey\u2019ve highlighted a really important blind spot that exists in general research about livestock trends globally,\u201d said Retta Bruegger, a rangeland ecologist at Colorado State University, who was not involved in the paper. \u201cI think the implications for rangeland health are really important here.\u201d<\/p>\n<p>Drought and wildfire sprang to her mind as potentially fruitful avenues of future research for scientists.<\/p>\n<p>Bruegger, who works with ranchers on Colorado\u2019s western slope, added that the paper underscores researchers\u2019 need to pay attention to historical livestocking trends, particularly in the West. \u201cSometimes we have this idea [that] the numbers of livestock on our public rangelands in the West are constant or maybe they\u2019re increasing and they\u2019re really not, according to the paper,\u201d she said. The new work \u201chighlights the need to really be engaged with the actual trends that are happening as we think about ecology and landscapes.\u201d<\/p>\n<p>Sala is excited by the many research opportunities his paper suggests. Even something as well-understood as plants\u2019 ability to trap carbon must be explored more, he said. It\u2019s not enough to simply suspect that flora no longer exposed to grazing will store more carbon, he said. \u201cWe need to find out how much, where, and when.

We make our news on climate and the environment freely available to you and anyone who wants it.<\/p>\n<p>That\u2019s not all. We also share our news for free with scores of other media organizations around the country. Many of them can\u2019t afford to do environmental journalism of their own. We\u2019ve built bureaus from coast to coast to report local stories, collaborate with local newsrooms and co-publish articles so that this vital work is shared as widely as possible.<\/p>\n<p>Two of us launched ICN in 2007. Six years later we earned a Pulitzer Prize for National Reporting, and now we run the oldest and largest dedicated climate newsroom in the nation. We tell the story in all its complexity. We hold polluters accountable. We expose environmental injustice. We debunk misinformation. We scrutinize solutions and inspire action.<\/p>\n<p>Donations from readers like you fund every aspect of what we do.
