Mixed crop and livestock farming is practiced on every inhabited continent, but it is most widespread across Western and Central Europe, the US Great Plains and Corn Belt, sub-Saharan Africa, and large parts of South and East Asia. These systems, where farmers grow crops and raise animals on the same land or in close coordination, are responsible for roughly 50% of global meat production and up to 90% of the world’s milk supply.
Western and Central Europe
Europe has the longest continuous tradition of mixed farming at a commercial scale. The system stretches from Ireland in the west through central Europe and into Russia. Agricultural geographer Derwent Whittlesey, whose classification is still widely referenced, divided Europe into three broad zones: a dairying belt covering the British Isles, Scandinavia, and coastal regions of France, Germany, and the Low Countries; a commercial crops and livestock zone across western and central Europe; and a more subsistence-oriented crops and livestock zone across eastern Europe, the Balkans, and European Russia north of the steppe.
In practice, this means countries like France, Germany, Poland, the Netherlands, Belgium, and the Czech Republic have deep roots in mixed farming. Farmers in these regions typically rotate cereal grains, root vegetables, and forage crops while raising cattle, pigs, or sheep. The mild, humid climate and fertile soils allow year-round integration of animal and crop production, with manure cycling back into cropland to maintain soil quality.
The US Great Plains and Corn Belt
In the United States, mixed crop and livestock farming has historically been concentrated in the Great Plains, a region that contains 59% of the country’s total grassland and 43% of its cropland. States like Kansas, Oklahoma, and Texas have a long tradition of dual-use systems where cattle graze on wheat fields during winter before the grain is harvested. In the western Corn Belt, Nebraska, South Dakota, and North Dakota, farmers graze cattle on corn residue after harvest. About 50% of corn residue acres in Nebraska are used for grazing, while Kansas, North Dakota, and South Dakota currently graze only about 20% of their available corn residue.
That said, integration has declined sharply over the past century. Between 1925 and 2002, the number of farms combining crops and livestock fell by 72 to 80% in the Northern and Central Plains, though the Southern Plains saw only a 13% drop. North Dakota and South Dakota experienced a further 60% decline between 2002 and 2012 alone. The trend in the Corn Belt has been toward specialization: farms that grow only crops or raise only animals, rarely both. State-level programs in Nebraska, South Dakota, Minnesota, and North Dakota now run online exchanges that connect crop farmers who have residue or cover crops with livestock producers who need grazing land, an effort to rebuild these integrated systems.
Sub-Saharan Africa
Mixed crop and livestock farming is the backbone of agriculture across much of sub-Saharan Africa, particularly in the semiarid drylands of West Africa. This belt spans 11 countries between roughly 7°N and 19°N latitude, stretching from Senegal and Mali in the west to Chad and beyond in the east. The region divides into two main zones. The Sahelian zone covers about 1.3 million square kilometers with annual rainfall between 150 and 600 mm and temperatures from 25 to 31°C. The Sudanian zone to its south is larger at 1.7 million square kilometers, wetter (600 to 1,200 mm of rain per year), and slightly cooler.
In both zones, the majority of the population depends on low-input farming systems that combine crop production with livestock keeping. Cattle, goats, and sheep graze on natural pastures and browse on trees and shrubs during the growing season, then feed on crop residues after harvest. This cycling of resources is essential in a region where synthetic fertilizer and supplemental feed are expensive or unavailable. Farmers rely on animal manure to maintain soil fertility for millet, sorghum, cowpeas, and groundnuts.
East Africa follows a similar pattern. The highlands of Ethiopia, Kenya, Tanzania, and Uganda support dense populations of smallholder farmers who grow maize, beans, and teff alongside cattle and small ruminants. These highland mixed systems are among the most productive smallholder zones in the continent.
South and East Asia
Asia holds some of the world’s most intensive small-scale mixed farming systems. In South Asia, particularly India, Bangladesh, and Nepal, smallholders commonly grow rice, wheat, or pulses while keeping dairy cattle or buffalo. India’s enormous milk output, the largest of any country, comes overwhelmingly from these mixed systems rather than from specialized dairy operations. Crop residues like rice straw serve as animal feed, while manure returns nutrients to the fields.
In Southeast Asia, countries like Vietnam, Thailand, Indonesia, and the Philippines have long traditions of integrating rice paddies with fish, poultry, or pig production. Chinese agriculture historically combined grain crops with pigs and poultry in tightly recycled village-level systems, though rapid industrialization has pushed many operations toward specialization in recent decades.
Why Mixed Farming Dominates Global Food Production
Despite the trend toward specialization in wealthy countries, mixed systems still produce more of the world’s food than any other farming type. They account for roughly half of all meat consumed globally and about three-quarters of the world’s milk supply. The reason is straightforward: most of the world’s farmers are smallholders in Africa, Asia, and Latin America, and for them, keeping both crops and animals on the same land is a practical strategy for managing risk, maintaining soil fertility, and diversifying income.
The biological logic is simple. Livestock eat crop residues and graze on land between growing seasons, converting material that would otherwise decompose unused into manure, milk, and meat. Manure returns nitrogen and other nutrients to the soil, reducing or eliminating the need for synthetic fertilizer. Research from the USDA has shown that manure additions can produce crop yields that exceed those from equivalent amounts of commercial fertilizer, likely because manure also improves soil structure, moisture retention, and micronutrient availability. Rotating between crops and pasture also helps break pest and disease cycles that build up under continuous cropping.
A Shift Back Toward Integration
In the United States and parts of Europe, there is growing interest in re-integrating crops and livestock after decades of separation. Federal and state programs now offer grants, technical assistance, and carbon credit opportunities to farmers who adopt regenerative practices, including rotational grazing on cropland. As of 2026, over a third of US farmers engage with at least one regenerative agriculture principle, driven by a combination of government incentives, consumer demand, and documented on-farm benefits like lower input costs and improved soil health.
Diverse grassland systems also show environmental advantages. Native mixed-species grasslands act as sinks for methane, while intensively managed monoculture pastures produce higher nitrous oxide emissions, a potent greenhouse gas. Reintroducing livestock onto cropland in planned rotational systems can rebuild soil carbon stores, reduce the need for nitrogen fertilizer, and support biodiversity through habitat variety. For farmers in the Great Plains and Corn Belt, the practical appeal is that grazing crop residues and cover crops turns a cost (managing leftover plant material) into revenue (livestock weight gain), while simultaneously improving the soil for the next planting season.
