Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed.
Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labor are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional rainfalls.
Extensive farming is found in the mid-latitude sections of most continents, as well as in desert regions where water for cropping is not available. The nature of extensive farming means it requires less rainfall than intensive farming. The farm is usually large in comparison with the numbers working and money spent on it. In 1957, most parts of Western Australia had pastures so poor that only one sheep to the square mile could be supported.[1]
Just as the demand has led to the basic division of cropping and pastoral activities, these areas can also be subdivided depending on the region's rainfall, vegetation type and agricultural activity within the area and the many other parentheses related to this data.
Extensive farming has a number of advantages over intensive farming:
Extensive farming can have the following problems:[3]
Extensive farming was once thought to produce more methane and nitrous oxide per kg of milk than intensive farming.[4] One study estimated that the "carbon footprint" per billion kg (2.2 billion lb.) of milk produced in 2007 was 37 percent that of equivalent milk production in 1944.[5] However, a more recent study by Centre de coopération internationale en recherche agronomique pour le développement found that extensive livestock systems impact the environment less than intensive systems.[6]

Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed.
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area. Most commercial agriculture is intensive in one or more ways. Forms that rely heavily on industrial methods are often called industrial agriculture, which is characterized by technologies designed to increase yield. Techniques include planting multiple crops per year, reducing the frequency of fallow years, improving cultivars, mechanised agriculture, controlled by increased and more detailed analysis of growing conditions, including weather, soil, water, weeds, and pests. Modern methods frequently involve increased use of non-biotic inputs, such as fertilizers, plant growth regulators, pesticides, and antibiotics for livestock. Intensive farms are widespread in developed nations and increasingly prevalent worldwide. Most of the meat, dairy products, eggs, fruits, and vegetables available in supermarkets are produced by such farms. Some intensive farms can use sustainable methods, although this typically necessitates higher inputs of labor or lower yields. Sustainably increasing agricultural productivity, especially on smallholdings, is an important way to decrease the amount of land needed for farming and slow and reverse environmental degradation caused by processes such as deforestation. Intensive animal farming involves large numbers of animals raised on a relatively small area of land, for example by rotational grazing, or sometimes as concentrated animal feeding operations. These methods increase the yields of food and fiber per unit land area compared to those of extensive animal husbandry; concentrated feed is brought to seldom-moved animals, or, with rotational grazing, the animals are repeatedly moved to fresh forage.
Hill farming or terrace farming is an extensive farming in upland areas, primarily rearing sheep, although historically cattle were often reared extensively in upland areas. Fell farming is the farming of fells, a fell being an area of uncultivated high ground used as common grazing. It is a term commonly used in Northern England, especially in the Lake District and the Pennine Dales. Elsewhere, the terms hill farming or pastoral farming are more commonly used. Cattle farming in the hills is usually restricted by a scarcity of winter fodder, and hill sheep, grazing at about two hectares per head, are often taken to lowland areas for fattening. Modern hill farming is often heavily dependent on state subsidy, for example in the United Kingdom it received support from the European Union's Common Agricultural Policy. Improved, sown pasture and drained moorland can be stocked more heavily, at approximately one sheep per 0.26 hectares.
Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins. Pigs are amenable to many different styles of farming: intensive commercial units, commercial free range enterprises, or extensive farming (being allowed to wander around a village, town or city, or tethered in a simple shelter or kept in a pen outside the owner's house). Historically, farm pigs were kept in small numbers and were closely associated with the residence of the owner, or in the same village or town. They were valued as a source of meat and fat, and for their ability to convert inedible food into meat and manure, and were often fed household food waste when kept on a homestead. Pigs have been farmed to dispose of municipal garbage on a large scale. All these forms of pig farm are in use today, though intensive farms are by far the most popular, due to their potential to raise a large amount of pigs in a very cost-efficient manner. In developed nations, commercial farms house thousands of pigs in climate-controlled buildings. Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods, cosmetics, and medical use.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
