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.
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
Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water.
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 ...
Examples of environmental impacts of animal agriculture: Meat production is a main driver of deforestation in Venezuela; Pigs in intensive farming; Testing Australian sheep for exhaled methane production to reduce greenhouse gas emissions from agriculture; Farms often pump their animal waste directly into a large lagoon, which has environmental consequences.
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.

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 ...
Silvopasture (silva is forest in Latin) is the practice of integrating trees, forage, and the grazing of domesticated animals in a mutually beneficial way. [1] It utilizes the principles of managed grazing, and it is one of several distinct forms of agroforestry. [2] If done correctly, silvopastures can count as Nature-based solutions to ...
