Dairy cattle grazing in Germany. In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
A catt of the Bakhtiari people, Chaharmahal and Bakhtiari Province, Iran Global map of pastoralism, its origins and historical development [1]. Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands for grazing, historically by nomadic people who moved around with their herds.

A study in 2019 focused on linkages between water usage and animal agricultural practices in China. [51] The results of the study showed that water resources were being used primarily for animal agriculture; the highest categories were animal husbandry, agriculture, slaughtering and processing of meat, fisheries, and other foods.
Livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural freshwater needs, while only supplying 18% of the global calorie intake. Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest. [93]: 746–747
Conservation grazing or targeted grazing [1] is the use of semi-feral or domesticated grazing livestock to maintain and increase the biodiversity of natural or semi-natural grasslands, heathlands, wood pasture, wetlands and many other habitats.
An indicator of a better functioning environment is newly sprouting diversity of plants and a return or increase of wildlife. Don't limit the management tools you use. The eight tools for managing natural resources are money/labor, human creativity, grazing, animal impact, fire, rest, living organisms and science/technology. To be successful ...
Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change [2] between grazing events. Successful planned grazing strategies have been in support of the American bison of the Great Plains, [3] [4] or migratory wildebeest of the African savannas, [5] or by holistic planned ...
Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater. Pollutants from farming include sediments, nutrients, pathogens, pesticides, metals, and salts. [46] Animal agriculture has an outsized impact on pollutants that enter the environment.
