142-416: Pastoralism is a form of animal husbandry where domesticated animals (known as " livestock ") are released onto large vegetated outdoor lands ( pastures ) for grazing , historically by nomadic people who moved around with their herds . The animal species involved include cattle , camels , goats , yaks , llamas , reindeer , horses , and sheep . Pastoralism occurs in many variations throughout

284-562: A common-pool resource , such as grazing lands used for pastoralism, can be managed more sustainably through community groups and cooperatives than through privatization or total governmental control. Ostrom was awarded a Nobel Memorial Prize in Economic Sciences for her work. Pastoralists in the Sahel zone in Africa were held responsible for the depletion of resources. The depletion of resources

426-506: A British interactive farm in an outbreak in 2009. Historic farms such as those in the United States offer farmstays and "a carefully curated version of farming to those willing to pay for it", sometimes giving visitors a romanticised image of a pastoral idyll from an unspecified time in the pre-industrial past. Hunter-gatherer Hunting and gathering was humanity's original and most enduring successful competitive adaptation in

568-504: A Farm " describes a farmer named MacDonald and the various animals he keeps, celebrating the noises they each make. Many urban children experience animal husbandry for the first time at a petting farm ; in Britain, some five million people a year visit a farm of some kind. This presents some risk of infection , especially if children handle animals and then fail to wash their hands ; a strain of E. coli infected 93 people who had visited

710-518: A day, whereas people in agricultural and industrial societies work on average 8.8 hours a day. Sahlins' theory has been criticized for only including time spent hunting and gathering while omitting time spent on collecting firewood, food preparation, etc. Other scholars also assert that hunter-gatherer societies were not "affluent" but suffered from extremely high infant mortality, frequent disease, and perennial warfare. Researchers Gurven and Kaplan have estimated that around 57% of hunter-gatherers reach

852-559: A diet high in protein and low in other macronutrients results in the body using the protein as energy, possibly leading to protein deficiency. Lean meat especially becomes a problem when animals go through a lean season that requires them to metabolize fat deposits. In areas where plant and fish resources are scarce, hunter-gatherers may trade meat with horticulturalists for carbohydrates . For example, tropical hunter-gatherers may have an excess of protein but be deficient in carbohydrates, and conversely tropical horticulturalists may have

994-446: A fertiliser, returning minerals and organic matter to the soil in a semi-closed organic system. Although all mammals produce milk to nourish their young, the cow is predominantly used throughout the world to produce milk and milk products for human consumption. Other animals used to a lesser extent for this purpose include sheep, goats, camels, buffaloes, yaks, reindeer, horses and donkeys. All these animals have been domesticated over

1136-426: A market economy are not excluded. The boundaries between states impact the viability of subsistence and trade relations with cultivators. Pastoralist strategies typify effective adaptation to the environment. Precipitation differences are evaluated by pastoralists. In East Africa, different animals are taken to specific regions throughout the year that corresponds to the seasonal patterns of precipitation. Transhumance

1278-773: A more constant supply of sustenance. In 2018, 9000-year-old remains of a female hunter along with a toolkit of projectile points and animal processing implements were discovered at the Andean site of Wilamaya Patjxa, Puno District in Peru . A 2020 study inspired by this discovery found that of 27 identified burials with hunter gatherers of a known sex who were also buried with hunting tools, 11 were female hunter gatherers, while 16 were male hunter gatherers. Combined with uncertainties, these findings suggest that anywhere from 30 to 50 percent of big game hunters were female. A 2023 study that looked at studies of contemporary hunter gatherer societies from

1420-500: A paper entitled, " Notes on the Original Affluent Society ", in which he challenged the popular view of hunter-gatherers lives as "solitary, poor, nasty, brutish and short", as Thomas Hobbes had put it in 1651. According to Sahlins, ethnographic data indicated that hunter-gatherers worked far fewer hours and enjoyed more leisure than typical members of industrial society, and they still ate well. Their "affluence" came from

1562-487: A plough to increase production of crops, and drawing a sledge, and later a cart, to bring the produce home from the field. Draught animals were first used about 4,000 BC in the Middle East, increasing agricultural production immeasurably. In southern Asia, the elephant was domesticated by 6,000 BC. Fossilised chicken bones dated to 5040 BC have been found in northeastern China, far from where their wild ancestors lived in

1704-832: A quarter of the total population—living on about 43 percent of the continent's total land mass." Pastoralists manage rangelands covering about a third of the Earth's terrestrial surface and are able to produce food where crop production is not possible. Pastoralism has been shown, "based on a review of many studies, to be between 2 and 10 times more productive per unit of land than the capital intensive alternatives that have been put forward". However, many of these benefits go unmeasured and are frequently squandered by policies and investments that seek to replace pastoralism with more capital intensive modes of production. They have traditionally suffered from poor understanding, marginalization and exclusion from dialogue. The Pastoralist Knowledge Hub, managed by

1846-419: A radius of a hundred to five hundred kilometers. Pastoralists and their livestock have impacted the environment. Lands long used for pastoralism have transformed under the forces of grazing livestock and anthropogenic fire . Fire was a method of revitalizing pastureland and preventing forest regrowth. The collective environmental weights of fire and livestock browsing have transformed landscapes in many parts of

1988-407: A result of the increasing importance of both intensive agriculture and pastoralism. Both agriculture and pastoralism developed alongside each other, with continuous interactions. A different theory suggests that pastoralism evolved from the hunting and gathering . Hunters of wild goats and sheep were knowledgeable about herd mobility and the needs of the animals. Such hunters were mobile and followed

2130-562: A significant impact on the world environment. Both production and consumption of animal products have increased rapidly. Since 1950, meat production has tripled, whereas the production of dairy products doubled and that of eggs almost increased fourfold. Meanwhile, meat consumption has nearly doubled worldwide. Developing countries had a surge in meat consumption, particularly of monogastric livestock. Animal husbandry drives climate change, ocean acidification, and biodiversity loss, and kills 60 billion animals annually. It uses between 20 and 33% of

2272-578: A size of a few dozen people. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago, and after this was replaced only gradually with the spread of the Neolithic Revolution . The Late Pleistocene witnessed the spread of modern humans outside of Africa as well as the extinction of all other human species. Humans spread to the Australian continent and

2414-816: A small area and given supplementary heating. Litter on the floor absorbs the droppings and the area occupied is expanded as they grow. Feed and water is supplied automatically and the lighting is controlled. The birds may be harvested on several occasions or the whole shed may be cleared at one time. A similar rearing system is usually used for turkeys, which are less hardy than chickens, but they take longer to grow and are often moved on to separate fattening units to finish. Ducks are particularly popular in Asia and Australia and can be killed at seven weeks under commercial conditions. Aquaculture has been defined as "the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants and implies some form of intervention in

2556-405: A smaller selection of (often larger) game and gathering a smaller selection of food. This specialization of work also involved creating specialized tools such as fishing nets , hooks, and bone harpoons . The transition into the subsequent Neolithic period is chiefly defined by the unprecedented development of nascent agricultural practices. Agriculture originated as early as 12,000 years ago in

2698-432: A surplus of carbohydrates but inadequate protein. Trading may thus be the most cost-effective means of acquiring carbohydrate resources. Hunter-gatherer societies manifest significant variability, depending on climate zone / life zone , available technology, and societal structure. Archaeologists examine hunter-gatherer tool kits to measure variability across different groups. Collard et al. (2005) found temperature to be

2840-484: A sustainable approach to land use. Animal husbandry Animal husbandry is the branch of agriculture concerned with animals that are raised for meat , fibre , milk , or other products. It includes day-to-day care, management, production, nutrition, selective breeding , and the raising of livestock . Husbandry has a long history, starting with the Neolithic Revolution when animals were first domesticated , from around 13,000 BC onwards, predating farming of

2982-483: A typical broiler chicken at eight weeks old was 4.8 times as heavy as a bird of similar age in 1957, while in the thirty years to 2007, the average milk yield of a dairy cow in the United States nearly doubled. Good husbandry, proper feeding, and hygiene are the main contributors to animal health on the farm, bringing economic benefits through maximised production. When, despite these precautions, animals still become sick, they are treated with veterinary medicines , by

3124-550: A week. At the other extreme, in the more developed parts of the world, animals are often intensively managed ; dairy cows may be kept in zero-grazing conditions with all their forage brought to them; beef cattle may be kept in high density feedlots ; pigs may be housed in climate-controlled buildings and never go outdoors; poultry may be reared in barns and kept in cages as laying birds under lighting-controlled conditions. In between these two extremes are semi-intensive, often family-run farms where livestock graze outside for much of

3266-492: A wide geographical area, thus there were regional variations in lifestyles. However, all the individual groups shared a common style of stone tool production, making knapping styles and progress identifiable. This early Paleo-Indian period lithic reduction tool adaptations have been found across the Americas, utilized by highly mobile bands consisting of approximately 25 to 50 members of an extended family. The Archaic period in

3408-517: Is a deciduous tree. In China, Korea and Japan however, two generations are normal, and in the tropics, multiple generations are expected. Most production of silk occurs in the Far East, with a synthetic diet being used to rear the silkworms in Japan. Insects form part of the human diet in many cultures. In Thailand, crickets are farmed for this purpose in the north of the country, and palm weevil larvae in

3550-451: Is a variation in genetic makeup of the farm animals driven mainly by natural and human based selection. For example, pastoralists in large parts of Sub Saharan Africa are preferring livestock breeds which are adapted to their environment and able to tolerate drought and diseases. However, in other animal production systems these breeds are discouraged and more productive exotic ones are favored. This situation could not be left unaddressed due to

3692-483: Is destroyed by clearing forests and converting land to grow feed crops and for grazing, while predators and herbivores are frequently targeted because of a perceived threat to livestock profits; for example, animal husbandry causes up to 91% of the deforestation in the Amazon region . In addition, livestock produce greenhouse gases . Cows produce some 570 million cubic metres of methane per day, that accounts for 35 to 40% of

3834-459: Is implausible, and yet it is applied in development projects around the globe, motivating the destruction of community and other governance systems that have managed sustainable pastoral systems for thousands of years. The outcomes have often been disastrous. In her book Governing the Commons , Elinor Ostrom showed that communities were not trapped and helpless amid diminishing commons. She argued that

3976-678: Is inhospitable to large scale economic exploitation and maintain their subsistence based on hunting and gathering, as well as incorporating a small amount of manioc horticulture that supplements, but is not replacing, reliance on foraged foods. Evidence suggests big-game hunter-gatherers crossed the Bering Strait from Asia (Eurasia) into North America over a land bridge ( Beringia ), that existed between 47,000 and 14,000 years ago. Around 18,500–15,500 years ago, these hunter-gatherers are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between

4118-427: Is mainly derived from cereals and cereal by-products, fats and oils and sugar-rich foods, while protein may come from fish or meat meal, milk products, legumes and other plant foods, often the by-products of vegetable oil extraction. Pigs and poultry are non-ruminants and unable to digest the cellulose in grass and other forages, so they are fed entirely on cereals and other high-energy foodstuffs. The ingredients for

4260-455: Is managed by farmers with a view to encouraging traits seen as desirable. These include hardiness, fertility, docility, mothering abilities, fast growth rates, low feed consumption per unit of growth, better body proportions, higher yields, and better fibre qualities. Undesirable traits such as health defects and aggressiveness are selected against. Selective breeding has been responsible for large increases in productivity. For example, in 2007,

4402-529: Is much higher, which is evident in the East African grasslands of pastoralist populations. However, the property rights structure is only one of the many different parameters that affect the sustainability of resources, and common or private property per se, does not necessarily lead to sustainability. Some pastoralists supplement herding with hunting and gathering, fishing and/or small-scale farming or pastoral farming . Mobility allows pastoralists to adapt to

4544-409: Is never total but is striking when viewed in an evolutionary context. One of humanity's two closest primate relatives, chimpanzees , are anything but egalitarian, forming themselves into hierarchies that are often dominated by an alpha male . So great is the contrast with human hunter-gatherers that it is widely argued by paleoanthropologists that resistance to being dominated was a key factor driving

4686-456: Is no single universally agreed definition of which species are livestock. Widely agreed types of livestock include cattle for beef and dairy, sheep, goats, pigs, and poultry. Various other species are sometimes considered livestock, such as horses, while poultry birds are sometimes excluded. In some parts of the world, livestock includes species such as buffalo, and the South American camelids,

4828-456: Is not necessarily a one-way process. It has been argued that hunting and gathering represents an adaptive strategy , which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in

4970-467: Is now frowned on in many countries because of the risk that it may lead to antimicrobial resistance in livestock and in humans. Governments are concerned with zoonoses , diseases that humans may acquire from animals. Wild animal populations may harbour diseases that can affect domestic animals which may acquire them as a result of insufficient biosecurity . An outbreak of Nipah virus in Malaysia in 1999

5112-461: Is only part of the purpose of keeping an animal which may also be used as a beast of burden or to draw a plough, or for the production of fibre, meat and leather, with the dung being used for fuel or for the improvement of soil fertility . Sheep and goats may be favoured for dairy production in climates and conditions that do not suit dairy cows. Meat , mainly from farmed animals, is a major source of dietary protein and essential nutrients around

5254-582: Is practical and down to earth, and anti-intellectual. Farm animals are widespread in books and songs for children; the reality of animal husbandry is often distorted, softened, or idealized, giving children an almost entirely fictitious account of farm life. The books often depict happy animals free to roam in attractive countryside, a picture completely at odds with the realities of the impersonal, mechanized activities involved in modern intensive farming . Pigs, for example, appear in several of Beatrix Potter 's "little books", as Piglet in A.A. Milne 's Winnie

5396-481: Is practiced in different climates and environments with daily movement and seasonal migration. Pastoralists are among the most flexible populations. Pastoralist societies have had field armed men protect their livestock and their people and then to return into a disorganized pattern of foraging. The products of the herd animals are the most important resources, although the use of other resources, including domesticated and wild plants, hunted animals, and goods accessible in

5538-538: Is seasonal, for example in the temperate summer or tropical rainy season , so some areas of the crop are set aside to be cut and preserved, either as hay (dried grass), or as silage (fermented grass). Other forage crops are also grown and many of these, as well as crop residues, can be ensiled to fill the gap in the nutritional needs of livestock in the lean season. Extensively reared animals may subsist entirely on forage, but more intensively kept livestock will require energy and protein-rich foods in addition. Energy

5680-405: Is the field of study whereby food plants of various peoples and tribes worldwide are documented. Most hunter-gatherers are nomadic or semi-nomadic and live in temporary settlements. Mobile communities typically construct shelters using impermanent building materials, or they may use natural rock shelters, where they are available. Some hunter-gatherer cultures, such as the indigenous peoples of

5822-480: Is the migration of livestock and pastoralists between seasonal pastures. In the Himalayas , pastoralists have often historically and traditionally depended on rangelands lying across international borders. The Himalayas contain several international borders, such as those between India and China, India and Nepal, Bhutan and China, India and Pakistan, and Pakistan and China. With the growth of nation states in Asia since

5964-634: Is vital for creating knowledge through the networks of linked societies. Pastoralists produce food in the world's harshest environments, and pastoral production supports the livelihoods of rural populations on almost half of the world's land. Several hundred million people are pastoralists, mostly in Africa and Asia . ReliefWeb reported that "Several hundred million people practice pastoralism—the use of extensive grazing on rangelands for livestock production, in over 100 countries worldwide. The African Union estimated that Africa has about 268 million pastoralists—over

6106-469: The Fertile Crescent , Ancient India , Ancient China , Olmec , Sub-Saharan Africa and Norte Chico . As a result of the now near-universal human reliance upon agriculture, the few contemporary hunter-gatherer cultures usually live in areas unsuitable for agricultural use. Archaeologists can use evidence such as stone tool use to track hunter-gatherer activities, including mobility. Ethnobotany

6248-559: The Ju'/hoansi people of Namibia, women help men track down quarry. In the Australian Martu, both women and men participate in hunting but with a different style of gendered division; while men are willing to take more risks to hunt bigger animals such as kangaroo for political gain as a form of "competitive magnanimity", women target smaller game such as lizards to feed their children and promote working relationships with other women, preferring

6390-746: The Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats , they migrated down the Pacific coast to South America. Hunter-gatherers would eventually flourish all over the Americas, primarily based in the Great Plains of the United States and Canada, with offshoots as far east as the Gaspé Peninsula on the Atlantic coast , and as far south as Chile , Monte Verde . American hunter-gatherers were spread over

6532-585: The Middle East , and also independently originated in many other areas including Southeast Asia , parts of Africa , Mesoamerica , and the Andes . Forest gardening was also being used as a food production system in various parts of the world over this period. Many groups continued their hunter-gatherer ways of life, although their numbers have continually declined, partly as a result of pressure from growing agricultural and pastoral communities. Many of them reside in

6674-510: The Middle East . Animal rights activists have objected to long-distance transport of animals; one result was the banning of live exports from New Zealand in 2003. Since the 18th century, the farmer John Bull has represented English national identity , first in John Arbuthnot 's political satires, and soon afterwards in cartoons by James Gillray and others including John Tenniel . He likes food, beer, dogs, horses, and country sports ; he

These regional adaptations would become the norm, with reliance less on hunting and gathering, with a more mixed economy of small game, fish , seasonally wild vegetables and harvested plant foods. Scholars like Kat Anderson have suggested that the term Hunter-gatherer is reductive because it implies that Native Americans never stayed in one place long enough to affect

6958-570: The Tibetan plateau , the Eurasian steppes , the Andes , Patagonia , the Pampas , Australia and many other places. As of 2019, between 200 million and 500 million people globally practiced pastoralism, and 75% of all countries had pastoral communities. Pastoral communities have different levels of mobility. The [[enclosure of common lands has led to Sedentary pastoralism becoming more common as

Grazing and browsing at the appropriate levels often can increase biodiversity in Mediterranean climate regions. Pastoralists shape ecosystems in different ways: some communities use fire to make ecosystems more suitable for grazing and browsing animals. One theory suggests that pastoralism developed from mixed farming . Bates and Lees proposed that

The verb to husband , meaning "to manage carefully", derives from an older meaning of husband , which in the 14th century referred to the ownership and care of a household or farm, but today means the "control or judicious use of resources", and in agriculture, the cultivation of plants or animals. Farmers and ranchers who raise livestock are considered to practice animal husbandry . The domestication of livestock

7384-898: The first crops . During the period of ancient societies like ancient Egypt , cattle , sheep , goats , and pigs were being raised on farms. Major changes took place in the Columbian exchange , when Old World livestock were brought to the New World, and then in the British Agricultural Revolution of the 18th century, when livestock breeds like the Dishley Longhorn cattle and Lincoln Longwool sheep were rapidly improved by agriculturalists, such as Robert Bakewell , to yield more meat, milk, and wool . A wide range of other species, such as horse , water buffalo , llama , rabbit , and guinea pig , are used as livestock in some parts of

7526-470: The nomads in the Middle East, while cattle and pigs were associated with more settled communities. The first wild animal to be domesticated was the dog . Half-wild dogs, perhaps starting with young individuals, may have been tolerated as scavengers and killers of vermin, and being naturally pack hunters , were predisposed to become part of the human pack and join in the hunt. Prey animals, sheep, goats, pigs and cattle, were progressively domesticated early in

7668-548: The 1800s to the present day found that women hunted in 79 percent of hunter gatherer societies. However, an attempted verification of this study found "that multiple methodological failures all bias their results in the same direction...their analysis does not contradict the wide body of empirical evidence for gendered divisions of labor in foraging societies". At the 1966 " Man the Hunter " conference, anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism

7810-799: The Americas began when Paleolithic hunter-gatherers entered North America from the North Asian mammoth steppe via the Beringia land bridge. During the 1970s, Lewis Binford suggested that early humans obtained food via scavenging , not hunting . Early humans in the Lower Paleolithic lived in forests and woodlands , which allowed them to collect seafood, eggs, nuts, and fruits besides scavenging. Rather than killing large animals for meat, according to this view, they used carcasses of such animals that had either been killed by predators or that had died of natural causes. Scientists have demonstrated that

7952-401: The Americas saw a changing environment featuring a warmer more arid climate and the disappearance of the last megafauna. The majority of population groups at this time were still highly mobile hunter-gatherers. Individual groups started to focus on resources available to them locally, however, and thus archaeologists have identified a pattern of increasing regional generalization, as seen with

Major extinctions were incurred in Australia beginning approximately 50,000 years ago and in the Americas about 15,000 years ago. Ancient North Eurasians lived in extreme conditions of the mammoth steppes of Siberia and survived by hunting mammoths , bison and woolly rhinoceroses. The settlement of

According to Hardin's paper, the pastoralist land use strategy was unstable and a cause of environmental degradation . One of Hardin's conditions for a "tragedy of the commons" is that people cannot communicate with each other or make agreements and contracts. Many scholars have pointed out that this

The Afar pastoralists in Ethiopia uses an indigenous communication method called dagu for information. This helps them in getting crucial information about climate and availability of pastures at various locations. There

8520-537: The Mediterranean. In ancient Egypt , cattle were the most important livestock, and sheep, goats, and pigs were also kept; poultry including ducks, geese, and pigeons were captured in nets and bred on farms, where they were force-fed with dough to fatten them. The Nile provided a plentiful source of fish. Honey bees were domesticated from at least the Old Kingdom, providing both honey and wax. In ancient Rome , all

For example, the San people or "Bushmen" of southern Africa have social customs that strongly discourage hoarding and displays of authority, and encourage economic equality via sharing of food and material goods. Karl Marx defined this socio-economic system as primitive communism . The egalitarianism typical of human hunters and gatherers

8946-857: The Pacific Northwest Coast and the Yokuts , lived in particularly rich environments that allowed them to be sedentary or semi-sedentary. Amongst the earliest example of permanent settlements is the Osipovka culture (14–10.3 thousand years ago), which lived in a fish-rich environment that allowed them to be able to stay at the same place all year. One group, the Chumash , had the highest recorded population density of any known hunter and gatherer society with an estimated 21.6 persons per square mile. Hunter-gatherers tend to have an egalitarian social ethos, although settled hunter-gatherers (for example, those inhabiting

As the ecological impact of this land management strategy is similar to the impact of such natural disturbances as grazing and wildfire , this agricultural system shares many beneficial characteristics with a natural habitat, including

9372-412: The age of 15. Of those that reach 15 years of age, 64% continue to live to or past the age of 45. This places the life expectancy between 21 and 37 years. They further estimate that 70% of deaths are due to diseases of some kind, 20% of deaths come from violence or accidents and 10% are due to degenerative diseases. Mutual exchange and sharing of resources (i.e., meat gained from hunting) are important in

Some authorities use much broader definitions to include fish in aquaculture , micro-livestock such as rabbits and rodents like guinea pigs , as well as insects from honey bees to crickets raised for human consumption . Animals are raised for a wide variety of products, principally meat , wool , milk , and eggs , but also including tallow , isinglass and rennet . Animals are also kept for more specialised purposes, such as to produce vaccines and antiserum (containing antibodies ) for medical use. Where fodder or other crops are grown alongside animals, manure can serve as

Those who practice pastoralism are called "pastoralists". Pastoralist herds interact with their environment, and mediate human relations with the environment as a way of turning uncultivated plants (like wild grass) into food. In many places, grazing herds on savannas and in woodlands can help maintain

Vitamins and minerals are added to balance the diet. Farmed fish are usually fed pelleted food. The breeding of farm animals seldom occurs spontaneously but

10082-477: The arguments put forward by Wilmsen. Doron Shultziner and others have argued that we can learn a lot about the life-styles of prehistoric hunter-gatherers from studies of contemporary hunter-gatherers—especially their impressive levels of egalitarianism. There are nevertheless a number of contemporary hunter-gatherer peoples who, after contact with other societies, continue their ways of life with very little external influence or with modifications that perpetuate

10224-437: The birds are unable to exhibit their normal behaviours. In the developed world, the majority of the poultry reared for meat is raised indoors in big sheds, with automated equipment under environmentally controlled conditions. Chickens raised in this way are known as broilers, and genetic improvements have meant that they can be grown to slaughter weight within six or seven weeks of hatching. Newly hatched chicks are restricted to

10366-502: The birds can roam as they will but are housed at night for their own protection, through semi-intensive systems where they are housed in barns and have perches, litter and some freedom of movement, to intensive systems where they are kept in cages. The battery cages are arranged in long rows in multiple tiers, with external feeders, drinkers, and egg collection facilities. This is the most labour saving and economical method of egg production but has been criticised on animal welfare grounds as

The flexibility of pastoralists to respond to environmental change

10792-479: The centuries, being bred for such desirable characteristics as fecundity, productivity, docility and the ability to thrive under the prevailing conditions. Whereas in the past cattle had multiple functions, modern dairy cow breeding has resulted in specialised Holstein Friesian-type animals that produce large quantities of milk economically. Artificial insemination is widely available to allow farmers to select for

10934-429: The changes in market preferences and climate all over the world, which could lead to changes in livestock diseases occurrence and decline forage quality and availability. Hence pastoralists can maintain farm animal genetic resources by conserving local livestock breeds. Generally conserving farm animal genetic resources under pastoralism is advantageous in terms of reliability and associated cost. Hardin's Tragedy of

11076-400: The country of Denmark in 2007. In addition, wealth transmission across generations was also a feature of hunter-gatherers, meaning that "wealthy" hunter-gatherers, within the context of their communities, were more likely to have children as wealthy as them than poorer members of their community and indeed hunter-gatherer societies demonstrate an understanding of social stratification. Thus while

11218-515: The countryside to assist in pollination. Sericulture , the rearing of silkworms, was first adopted by the Chinese during the Shang dynasty . The only species farmed commercially is the domesticated silkmoth . When it spins its cocoon , each larva produces an exceedingly long, slender thread of silk. The larvae feed on mulberry leaves and in Europe, only one generation is normally raised each year as this

11360-497: The creation of protected areas. Some pastoralists are constantly moving, which may put them at odds with sedentary people of towns and cities. The resulting conflicts can result in war for disputed lands. These disputes are recorded in ancient times in the Middle East, as well as for East Asia. Other pastoralists are able to remain in the same location which results in longer-standing housing. Different mobility patterns can be observed: Somali pastoralists keep their animals in one of

11502-532: The developing world, either in arid regions or tropical forests. Areas that were formerly available to hunter-gatherers were—and continue to be—encroached upon by the settlements of agriculturalists. In the resulting competition for land use, hunter-gatherer societies either adopted these practices or moved to other areas. In addition, Jared Diamond has blamed a decline in the availability of wild foods, particularly animal resources. In North and South America , for example, most large mammal species had gone extinct by

11644-553: The diet until relatively recently, during the Late Stone Age in southern Africa and the Upper Paleolithic in Europe. Fat is important in assessing the quality of game among hunter-gatherers, to the point that lean animals are often considered secondary resources or even starvation food. Consuming too much lean meat leads to adverse health effects like protein poisoning , and can in extreme cases lead to death. Additionally,

11786-409: The economic systems of hunter-gatherer societies. Therefore, these societies can be described as based on a " gift economy ". A 2010 paper argued that while hunter-gatherers may have lower levels of inequality than modern, industrialised societies, that does not mean inequality does not exist. The researchers estimated that the average Gini coefficient amongst hunter-gatherers was 0.25, equivalent to

11928-541: The end of the Pleistocene —according to Diamond, because of overexploitation by humans, one of several explanations offered for the Quaternary extinction event there. As the number and size of agricultural societies increased, they expanded into lands traditionally used by hunter-gatherers. This process of agriculture-driven expansion led to the development of the first forms of government in agricultural centers, such as

12070-461: The environment around them. However, many of the landscapes in the Americas today are due to the way the Natives of that area originally tended the land. Anderson specifically looks at California Natives and the practices they utilized to tame their land. Some of these practices included pruning, weeding, sowing, burning, and selective harvesting. These practices allowed them to take from the environment in

12212-401: The environment, which opens up the possibility for both fertile and infertile regions to support human existence. Important components of pastoralism include low population density, mobility, vitality, and intricate information systems. The system is transformed to fit the environment rather than adjusting the environment to support the "food production system." Mobile pastoralists can often cover

12354-399: The evidence for early human behaviors for hunting versus carcass scavenging vary based on the ecology, including the types of predators that existed and the environment. According to the endurance running hypothesis , long-distance running as in persistence hunting , a method still practiced by some hunter-gatherer groups in modern times, was likely the driving evolutionary force leading to

12496-456: The evolution of certain human characteristics. This hypothesis does not necessarily contradict the scavenging hypothesis: both subsistence strategies may have been in use sequentially, alternately or even simultaneously. Starting at the transition between the Middle to Upper Paleolithic period, some 80,000 to 70,000 years ago, some hunter-gatherer bands began to specialize, concentrating on hunting

12638-613: The evolutionary emergence of human consciousness , language , kinship and social organization . Most anthropologists believe that hunter-gatherers do not have permanent leaders; instead, the person taking the initiative at any one time depends on the task being performed. Within a particular tribe or people, hunter-gatherers are connected by both kinship and band (residence/domestic group) membership. Postmarital residence among hunter-gatherers tends to be matrilocal, at least initially. Young mothers can enjoy childcare support from their own mothers, who continue living nearby in

12780-731: The farmer and the veterinarian . In the European Union, when farmers treat their own animals, they are required to follow the guidelines for treatment and to record the treatments given. Animals are susceptible to a number of diseases and conditions that may affect their health. Some, like classical swine fever and scrapie are specific to one type of stock, while others, like foot-and-mouth disease affect all cloven-hoofed animals. Animals living under intensive conditions are prone to internal and external parasites ; increasing numbers of sea lice are affecting farmed salmon in Scotland. Reducing

12922-444: The growing of crops for winter fodder gained ground. Peas, beans and vetches became common; they increased soil fertility through nitrogen fixation, allowing more livestock to be kept. Exploration and colonisation of North and South America resulted in the introduction into Europe of such crops as maize, potatoes, sweet potatoes and manioc, while the principal Old World livestock – cattle, horses, sheep and goats – were introduced into

13064-407: The hardening of political borders, land tenures , expansion of crop farming , and construction of fences and dedicated agricultural buildings all reduce the ability to move livestock around freely, leading to the rise of pastoral farming on established grazing-zones (sometimes called " ranches "). Sedentary pastoralists may also raise crops and livestock together in the form of mixed farming , for

13206-411: The harshest environments but they have evolved over the centuries. Somalis have well developed pastoral culture where complete system of life and governance has been refined. Somali poetry depicts humans interactions, pastoral animals, beasts on the prowl, and other natural things such the rain, celestial events and historic events of significance. Wise sage Guled Haji coined a proverb that encapsulates

13348-582: The herds on their seasonal rounds. Undomesticated herds were chosen to become more controllable for the proto-pastoralist nomadic hunter and gatherer groups by taming and domesticating them. Hunter-gatherers' strategies in the past have been very diverse and contingent upon the local environmental conditions, like those of mixed farmers. Foraging strategies have included hunting or trapping big game and smaller animals, fishing, collecting shellfish or insects, and gathering wild-plant foods such as fruits, seeds, and nuts. These diverse strategies for survival amongst

13490-466: The history of agriculture. Pigs were domesticated in the Near East between 8,500 and 8000 BC, sheep and goats in or near the Fertile Crescent about 8,500 BC, and cattle from wild aurochs in the areas of modern Turkey and Pakistan around 8,500 BC. A cow was a great advantage to a villager as she produced more milk than her calf needed, and her strength could be put to use as a working animal , pulling

13632-400: The idea that they were satisfied with very little in the material sense. Later, in 1996, Ross Sackett performed two distinct meta-analyses to empirically test Sahlin's view. The first of these studies looked at 102 time-allocation studies, and the second one analyzed 207 energy-expenditure studies. Sackett found that adults in foraging and horticultural societies work on average, about 6.5 hours

13774-732: The incorporation of irrigation into farming resulted in specialization. Advantages of mixed farming include reducing risk of failure, spreading labour, and re-utilizing resources. The importance of these advantages and disadvantages to different farmers or farming societies differs according to the sociocultural preferences of the farmers and the biophysical conditions as determined by rainfall, radiation, soil type, and disease. The increased productivity of irrigation agriculture led to an increase in population and an added impact on resources. Bordering areas of land remained in use for animal breeding. This meant that large distances had to be covered by herds to collect sufficient forage. Specialization occurred as

13916-473: The jungles of tropical Asia, but archaeologists believe that the original purpose of domestication was for the sport of cockfighting . Meanwhile, in South America, the llama and the alpaca had been domesticated, probably before 3,000 BC, as beasts of burden and for their wool. Neither was strong enough to pull a plough which limited the development of agriculture in the New World. Horses occur naturally on

14058-655: The last 10,000 years. Nowadays, some scholars speak about the existence within cultural evolution of the so-called mixed-economies or dual economies which imply a combination of food procurement (gathering and hunting) and food production or when foragers have trade relations with farmers. Some of the theorists who advocate this "revisionist" critique imply that, because the "pure hunter-gatherer" disappeared not long after colonial (or even agricultural) contact began, nothing meaningful can be learned about prehistoric hunter-gatherers from studies of modern ones (Kelly, 24–29; see Wilmsen ) Lee and Guenther have rejected most of

14200-530: The livestock known in ancient Egypt were available. In addition, rabbits were domesticated for food by the first century BC. To help flush them out from their burrows, the polecat was domesticated as the ferret , its use described by Pliny the Elder . In northern Europe, agriculture including animal husbandry went into decline when the Roman empire collapsed. Some aspects such as the herding of animals continued throughout

14342-662: The mid-twentieth century, mobility across the international borders in these countries have tended to be more and more restricted and regulated. As a consequence, the old, customary arrangements of trans-border pastoralism have generally tended to disintegrate, and trans-border pastoralism has declined. Within these countries, pastoralism is often at conflict these days with new modes of community forestry, such as Van Panchayats ( Uttarakhand ) and Community Forest User Groups ( Nepal ), which tend to benefit settled agricultural communities more. Frictions have also tended to arise between pastoralists and development projects such as dam-building and

14484-571: The middle-late Bronze Age and Iron Age societies were able to fully replace hunter-gatherers in their final stronghold located in the most densely forested areas. Unlike their Bronze and Iron Age counterparts, Neolithic societies could not establish themselves in dense forests, and Copper Age societies had only limited success. In addition to men, a single study found that women engage in hunting in 79% of modern hunter-gatherer societies. However, an attempted verification of this study found "that multiple methodological failures all bias their results in

14626-748: The migratory herds could also provide an evolutionary route towards nomadic pastoralism . Pastoralism occurs in uncultivated areas. Wild animals eat the forage from the marginal lands and humans survive from milk, blood, and often meat of the herds and often trade by-products like wool and milk for money and food . Pastoralists do not exist at basic subsistence . Pastoralists often compile wealth and participate in international trade. Pastoralists have trade relations with agriculturalists, horticulturalists , and other groups. Pastoralists are not extensively dependent on milk, blood, and meat of their herd. McCabe noted that when common property institutions are created, in long-lived communities, resource sustainability

14768-510: The most widely held position in the western world, a form of utilitarianism : that it is morally acceptable for humans to use non-human animals, provided that no unnecessary suffering is caused, and that the benefits to humans outweigh the costs to the livestock. An opposing view is that animals have rights , should not be regarded as property, are not necessary to use, and should never be used by humans. Live export of animals has risen to meet increased global demand for livestock such as in

14910-524: The natural world, occupying at least 90 percent of human history . Following the invention of agriculture , hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in most parts of the world. Across Western Eurasia, it was not until approximately 4,000 BC that farming and metallurgical societies completely replaced hunter-gatherers. These technologically advanced societies expanded faster in areas with less forest, pushing hunter-gatherers into denser woodlands. Only

15052-521: The needs of the state in reducing the autonomy and livelihoods of pastoral people. The violent herder–farmer conflicts in Nigeria , Mali , Sudan , Ethiopia and other countries in the Sahel and Horn of Africa regions have been exacerbated by climate change , land degradation , and population growth . It has also been shown that pastoralism supports human existence in harsh environments and often represents

15194-423: The only statistically significant factor to impact hunter-gatherer tool kits. Using temperature as a proxy for risk, Collard et al.'s results suggest that environments with extreme temperatures pose a threat to hunter-gatherer systems significant enough to warrant increased variability of tools. These results support Torrence's (1989) theory that the risk of failure is indeed the most important factor in determining

15336-501: The overall methane emissions of the planet. Further, livestock production is responsible for 65% of all human-related emissions of nitrous oxide . Since the 18th century, people have become increasingly concerned about the welfare of farm animals . Possible measures of welfare include longevity , behavior , physiology , reproduction , freedom from disease , and freedom from immunosuppression . Standards and laws for animal welfare have been created worldwide, broadly in line with

15478-480: The parasite burdens of livestock results in increased productivity and profitability. Where the condition is serious, governments impose regulations on import and export, on the movement of stock, quarantine restrictions and the reporting of suspected cases. Vaccines are available against certain diseases, and antibiotics are widely used where appropriate. At one time, antibiotics were routinely added to certain compound foodstuffs to promote growth, but this practice

15620-406: The particular traits that suit their circumstances. Whereas in the past cows were kept in small herds on family farms , grazing pastures and being fed hay in winter, nowadays there is a trend towards larger herds, more intensive systems, the feeding of silage and "zero grazing", a system where grass is cut and brought to the cow, which is housed year-round. In many communities, milk production

15762-554: The period. By the 11th century, the economy had recovered and the countryside was again productive. The Domesday Book recorded every parcel of land and every animal in England: "there was not one single hide, nor a yard of land, nay, moreover ... not even an ox, nor a cow, nor a swine was there left, that was not set down in [the king's] writ." For example, the royal manor of Earley in Berkshire , one of thousands of villages recorded in

15904-410: The promotion of biodiversity . This strategy is declining in Europe today due to the intensification of agriculture. The mechanized and chemical methods used are causing biodiversity to decline. Traditionally, animal husbandry was part of the subsistence farmer's way of life, producing not only the food needed by the family but also the fuel, fertiliser, clothing, transport and draught power. Killing

16046-503: The purpose of diversifying productivity, obtaining manure for organic farming , and improving pasture conditions for their livestock. Mobile pastoralism includes moving herds locally across short distances in search of fresh forage and water (something that can occur daily or even within a few hours); as well as transhumance , where herders routinely move animals between different seasonal pastures across regions; and nomadism , where nomadic pastoralists and their families move with

16188-1033: The rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated." In practice it can take place in the sea or in freshwater, and be extensive or intensive. Whole bays, lakes or ponds may be devoted to aquaculture, or the farmed animal may be retained in cages (fish), artificial reefs , racks or strings (shellfish). Fish and prawns can be cultivated in rice paddies , either arriving naturally or being introduced, and both crops can be harvested together. Fish hatcheries provide larval and juvenile fish, crustaceans and shellfish, for use in aquaculture systems. When large enough these are transferred to growing-on tanks and sold to fish farms to reach harvest size. Some species that are commonly raised in hatcheries include shrimps , prawns , salmon , tilapia , oysters and scallops . Similar facilities can be used to raise species with conservation needs to be released into

16330-660: The researchers agreed that hunter-gatherers were more egalitarian than modern societies, prior characterisations of them living in a state of egalitarian primitive communism were inaccurate and misleading. This study, however, exclusively examined modern hunter-gatherer communities, offering limited insight into the exact nature of social structures that existed prior to the Neolithic Revolution. Alain Testart and others have said that anthropologists should be careful when using research on current hunter-gatherer societies to determine

16472-452: The same camp. The systems of kinship and descent among human hunter-gatherers were relatively flexible, although there is evidence that early human kinship in general tended to be matrilineal . The conventional assumption has been that women did most of the gathering, while men concentrated on big game hunting. An illustrative account is Megan Biesele's study of the southern African Ju/'hoan, 'Women Like Meat'. A recent study suggests that

16614-646: The same direction...their analysis does not contradict the wide body of empirical evidence for gendered divisions of labor in foraging societies". Only a few contemporary societies of uncontacted people are still classified as hunter-gatherers, and many supplement their foraging activity with horticulture or pastoralism . Hunting and gathering was presumably the subsistence strategy employed by human societies beginning some 1.8 million years ago, by Homo erectus , and from its appearance some 200,000 years ago by Homo sapiens . Prehistoric hunter-gatherers lived in groups that consisted of several families resulting in

16756-503: The sexual division of labor was the fundamental organizational innovation that gave Homo sapiens the edge over the Neanderthals, allowing our ancestors to migrate from Africa and spread across the globe. A 1986 study found most hunter-gatherers have a symbolically structured sexual division of labor. However, it is true that in a small minority of cases, women hunted the same kind of quarry as men, sometimes doing so alongside men. Among

16898-421: The south. The crickets are kept in pens, boxes or drawers and fed on commercial pelleted poultry food, while the palm weevil larvae live on cabbage palm and sago palm trees, which limits their production to areas where these trees grow. Another delicacy of this region is the bamboo caterpillar , and the best rearing and harvesting techniques in semi-natural habitats are being studied. Animal husbandry has

17040-755: The steppes of Central Asia and their domestication began around 3,000 BC in the Black Sea and Caspian Sea region. Although horses were originally seen as a source of meat, their use as pack animals and for riding followed. Around the same time, the wild ass was being tamed in Egypt. Camels were domesticated soon after this, with the Bactrian camel in Mongolia and the Arabian camel becoming beasts of burden. By 1000 BC, caravans of Arabian camels were linking India with Mesopotamia and

17182-403: The structure of hunter-gatherer toolkits. One way to divide hunter-gatherer groups is by their return systems. James Woodburn uses the categories "immediate return" hunter-gatherers for egalitarianism and "delayed return" for nonegalitarian. Immediate return foragers consume their food within a day or two after they procure it. Delayed return foragers store the surplus food. Hunting-gathering

17324-765: The structure of societies in the paleolithic era, emphasising cross-cultural influences, progress and development that such societies have undergone in the past 10,000 years. As one moves away from the equator , the importance of plant food decreases and the importance of aquatic food increases. In cold and heavily forested environments, edible plant foods and large game are less abundant and hunter-gatherers may turn to aquatic resources to compensate. Hunter-gatherers in cold climates also rely more on stored food than those in warm climates. However, aquatic resources tend to be costly, requiring boats and fishing technology, and this may have impeded their intensive use in prehistory. Marine food probably did not start becoming prominent in

17466-539: The uplands of the United Kingdom, sheep are turned out on the fells in spring and graze the abundant mountain grasses untended, being brought to lower altitudes late in the year, with supplementary feeding being provided in winter. In rural locations, pigs and poultry can obtain much of their nutrition from scavenging, and in African communities, hens may live for months without being fed, and still produce one or two eggs

17608-603: The valleys. Animals can be kept extensively or intensively. Extensive systems involve animals roaming at will, or under the supervision of a herdsman, often for their protection from predators . Ranching in the Western United States involves large herds of cattle grazing widely over public and private lands. Similar cattle stations are found in South America, Australia and other places with large areas of land and low rainfall. Ranching systems have been used for sheep , deer , ostrich , emu , llama and alpaca . In

17750-813: The viability of hunting and gathering in the 21st century. One such group is the Pila Nguru (Spinifex people) of Western Australia , whose land in the Great Victoria Desert has proved unsuitable for European agriculture (and even pastoralism). Another are the Sentinelese of the Andaman Islands in the Indian Ocean , who live on North Sentinel Island and to date have maintained their independent existence, repelling attempts to engage with and contact them. The Savanna Pumé of Venezuela also live in an area that

17892-487: The whole range of available plant material. Cattle, sheep, goats, deer and antelopes are ruminants ; they digest food in two steps, chewing and swallowing in the normal way, and then regurgitating the semidigested cud to chew it again and thus extract the maximum possible food value. The dietary needs of these animals is mostly met by eating grass. Grasses grow from the base of the leaf-blade, enabling it to thrive even when heavily grazed or cut. In many climates grass growth

18034-523: The wild long before that. Fixed comb hives are used in many parts of the world and are made from any locally available material. In more advanced economies, where modern strains of domestic bee have been selected for docility and productiveness, various designs of hive are used which enable the combs to be removed for processing and extraction of honey. Quite apart from the honey and wax they produce, honey bees are important pollinators of crops and wild plants, and in many places hives are transported around

18176-529: The wild, or game fish for restocking waterways. Important aspects of husbandry at these early stages include selection of breeding stock, control of water quality and nutrition. In the wild, there is a massive amount of mortality at the nursery stage; farmers seek to minimise this while at the same time maximising growth rates. Bees have been kept in hives since at least the First Dynasty of Egypt , five thousand years ago, and man had been harvesting honey from

18318-473: The world's fresh water, Livestock, and the production of feed for them, occupy about a third of the Earth's ice-free land. Livestock production contributes to species extinction , desertification , and habitat destruction . and is the primary driver of the Holocene extinction . Some 70% of the agricultural land and 30% of Earth's land surface is involved directly or indirectly in animal husbandry. Habitat

18460-495: The world's meat is produced from animals grazing on open ranges or on enclosed pastures, the other half being produced intensively in various factory-farming systems; these are mostly cows, pigs or poultry, and often reared indoors, typically at high densities. Poultry, kept for their eggs and for their meat, include chickens, turkeys, geese and ducks. The great majority of laying birds used for egg production are chickens. Methods for keeping layers range from free-range systems, where

18602-764: The world, averaging about 8% of man's energy intake. The actual types eaten depend on local preferences, availability, cost and other factors, with cattle, sheep, pigs and goats being the main species involved. Cattle generally produce a single offspring annually which takes more than a year to mature; sheep and goats often have twins and these are ready for slaughter in less than a year; pigs are more prolific, producing more than one litter of up to about 11 piglets each year. Horses, donkeys, deer, buffalo, llamas, alpacas, guanacos and vicunas are farmed for meat in various regions. Some desirable traits of animals raised for meat include fecundity, hardiness, fast growth rate, ease of management and high food conversion efficiency. About half of

18744-416: The world, generally where environmentally effected characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming . Pastoralism remains a way of life in many geographic areas, including Africa,

18886-1016: The world. Insect farming , as well as aquaculture of fish , molluscs , and crustaceans , is widespread. Modern animal husbandry relies on production systems adapted to the type of land available. Subsistence farming is being superseded by intensive animal farming in the more developed parts of the world, where, for example, beef cattle are kept in high-density feedlots , and thousands of chickens may be raised in broiler houses or batteries . On poorer soil, such as in uplands, animals are often kept more extensively and may be allowed to roam widely, foraging for themselves. Animal agriculture at modern scale drives climate change , ocean acidification , and biodiversity loss . Most livestock are herbivores , except for pigs and chickens which are omnivores . Ruminants like cattle and sheep are adapted to feed on grass; they can forage outdoors or may be fed entirely or in part on rations richer in energy and protein, such as pelleted cereals. Pigs and poultry cannot digest

19028-489: The world. Fire has permitted pastoralists to tend the land for their livestock. Political boundaries are based on environmental boundaries. The Maquis shrublands of the Mediterranean region are dominated by pyrophytic plants that thrive under conditions of anthropogenic fire and livestock grazing. Nomadic pastoralists have a global food-producing strategy depending on the management of herd animals for meat, skin, wool, milk, blood, manure, and transport. Nomadic pastoralism

19170-531: The year, silage or hay is made to cover the times of year when the grass stops growing, and fertiliser, feed, and other inputs are brought onto the farm from outside. Animals used as livestock are predominantly herbivorous , the main exceptions being the pig and the chicken which are omnivorous. The herbivores can be divided into "concentrate selectors" which selectively feed on seeds, fruits and highly nutritious young foliage, "grazers" which mainly feed on grass, and "intermediate feeders" which choose their diet from

19312-415: Was actually triggered by a prior interference and punitive climate conditions. Hardin's paper suggested a solution to the problems, offering a coherent basis for privatization of land, which stimulates the transfer of land from tribal peoples to the state or to individuals. The privatized programs impact the livelihood of the pastoralist societies while weakening the environment. Settlement programs often serve

19454-417: Was driven by the need to have food on hand when hunting was unproductive. The desirable characteristics of a domestic animal are that it should be useful to the domesticator, should be able to thrive in his or her company, should breed freely, and be easy to tend. Domestication was not a single event, but a process repeated at various periods in different places. Sheep and goats were the animals that accompanied

19596-504: Was improved by Bakewell and in turn the Lincoln was used to develop the subsequent breed, named the New (or Dishley) Leicester. It was hornless and had a square, meaty body with straight top lines. These sheep were exported widely and have contributed to numerous modern breeds. Under his influence, English farmers began to breed cattle for use primarily as beef. Long-horned heifers were crossed with

19738-429: Was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member. Other characteristics Lee and DeVore proposed were flux in territorial boundaries as well as in demographic composition. At the same conference, Marshall Sahlins presented

19880-399: Was reduced by colonization. For example, mobility was limited in the Sahel region of Africa with settlement being encouraged. The population tripled and sanitation and medical treatment were improved. Pastoralists have mental maps of the value of specific environments at different times of year. Pastoralists have an understanding of ecological processes and the environment. Information sharing

20022-459: Was the common human mode of subsistence throughout the Paleolithic , but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples . The transition from hunting and gathering to agriculture

20164-540: Was traced back to pigs becoming ill after contact with fruit-eating flying foxes , their faeces and urine. The pigs in turn passed the infection to humans. Avian flu H5N1 is present in wild bird populations and can be carried large distances by migrating birds. This virus is easily transmissible to domestic poultry, and to humans living in close proximity with them. Other infectious diseases affecting wild animals, farm animals and humans include rabies , leptospirosis , brucellosis , tuberculosis and trichinosis . There
