Like all human systems, a society’s subsistence system is intricately linked to other aspects of culture such as kinship, politics, and religion. Although we can study these systems in isolation, it is important to remember that in the real world all aspects of culture overlap in complex ways. Consider harvest rituals, for example, which are religious ceremonies focused on improving the food supply. These rituals are shaped by religious beliefs as well as the demands and challenges of obtaining food. Likewise, subsistence systems are the economic base of every society. Working to put food on the table is the essential task of every family or household, and this work is the basis of a domestic economy that interacts with the modes of production and modes of exchange described in the Economics chapter.

When anthropologists first began to examine subsistence systems, they started like all scientists do, with classification. Early on, anthropologists saw the benefit of grouping similar societies into types, or categories, based on the range of practices they used in the quest for food. These groupings allowed for comparisons between cultures. At a basic level, societies can be divided into those that have an immediate return system for finding food and those that use a delayed return system. The residents of a small fishing village who eat the fish they catch each day have an immediate return on their labor. Farmers who must wait several months between the time they plant seeds and the time they harvest have a delayed return system.

Beyond this basic division, anthropologists recognize four general types of food system known as modes of subsistence. The four modes of subsistence are foraging, pastoralism, horticulture, and agriculture. Each mode is defined by the tasks involved in obtaining food as well as the way members of the society are organized socially to accomplish these tasks. Because each mode of subsistence is tailored to particular ecological conditions, we can think of each culture’s subsistence system as an adaptation, or a set of survival strategies uniquely developed to suit a particular environment. Because culture shapes the way we view and interact with the environment, different societies can adapt to similar environments in different ways. Foraging, sometimes known as hunting and gathering, describes societies that rely primarily on “wild” plant and animal food resources. Pastoralism is a subsistence system in which people raise herds of domesticated livestock. Horticulture is the small-scale cultivation of crops intended primarily for subsistence. Agriculture, the subsistence system used in the United States, involves the cultivation of domesticated plants and animals using technologies that allow for intensive use of the land.

When anthropologists analyze a subsistence system, they look for the dominant mode of subsistence, or the most typical way that members of a society procure food. So, while some people in the United States grow their own food or hunt wild animals, the dominant mode of subsistence is agriculture, and people obtain food primarily by purchasing it.

5.3.1 Foraging

“Why should we plant, when there are so many mongongos (type of nut) in the world?”

-/Xashe, !Kung forager^[1]

Foraging is a mode of subsistence defined by its reliance on wild plant and animal food resources already available in the environment rather than on domesticated species that have been altered by human intervention. Foragers use a remarkable variety of practices to procure meals. Hunting for animal protein is central to the foraging lifestyle and foragers capture and consume a wide variety of animals, from squirrels caught with a bow and arrow or blow dart to buffalo once killed by the dozens in communal hunts. Fishing for marine resources forms the basis for acquiring protein in many foraging communities and includes a range of practices from exploiting coastal shellfish and crab, to harvesting offshore resources such as deep sea fish and marine mammals such as whales and seals. Augmenting the protein from hunting or fishing, gathered wild plant resources, such as fruits, nuts, roots, tubers, and berries typically provide a large percentage of the calories that go into any meal. Gathering requires expert knowledge of where plant resources can be found, when they will be best to harvest, and how to prepare them for consumption. Foraging is the only immediate return subsistence system.

Foraging societies tend to have what is called a broad spectrum diet: a diet based on a wide range of resources. Many of the foods regularly eaten by foragers, such as insects and worms, would not necessarily be considered edible by many people in the United States. For example, many people do not know that earthworms are a good source of iron and high-quality protein, roughly equivalent to eggs, but that is exactly what anthropologists learned by studying the diet of foraging societies in Venezuela.^[2] Foragers are scientists of their own ecosystems, having acquired extensive knowledge of the natural world through experience that allows them to exploit many kinds of food resources. The Aché, a foraging group living in the subtropical rainforest in Paraguay, eat 33 different kinds of mammals, more than 15 species of fish, the adult forms of 5 insects, 10 types of larvae, and at least 14 kinds of honey. This is in addition to finding and collecting 40 species of plants.^[3] The !Kung foragers, who live in the Kalahari Desert in southern Africa, treasure the mongongo nut, which is tasty, high in protein, and abundant for most of the year, but they also hunt giraffes, six species of antelope, and many kinds of smaller game like porcupine.^[4]

In general, foraging societies are small, with low population densities of less than 5 people per square mile. Large families and communities are not necessarily desirable since more mouths to feed can equate to increased pressure to find food. Another factor that contributes to a lower population density is the fact that it is more difficult for the young and the elderly to participate in food procurement. Children only gradually acquire the skills necessary to successfully find food and generally do not make significant contributions to the group until their teenage years. Likewise, elders who can no longer produce enough food themselves expect to be cared for by others.^[5]

One important hallmark of foraging societies is their egalitarian social structure. Stark differences in wealth, which characterize many societies, are rare in foraging communities. One reason for this is that foragers have a different perspective on private property. Foraging societies tend to move their camps frequently to exploit various resources, so holding on to a lot of personal possessions or “wealth” is impractical. Foragers also place a high cultural value on generosity. Sharing of food and other resources is a social norm and a measure of a person’s goodness. Those who resist sharing what they have with others will be ridiculed, or could even become social outcasts.^[6] Over the long term, daily habits of giving and receiving reinforce social equality. This practice is also an important survival strategy that helps groups get through times of food scarcity.

Though foragers have high levels of social equality, not everyone is treated exactly the same. Gender inequality exists in many communities and develops from the fact that work among foragers is often divided along gender lines. Some jobs, such as hunting large animals, belong to men whose success in hunting gives them high levels of respect and prestige. While women do hunt in many communities and often contribute the majority of the group’s food through gathering, their work tends not to be as socially prestigious.^[7] Likewise, elders in foraging communities tend to command respect and enjoy a higher social status, particularly if they have skills in healing or ritual activities.

In 1651, the English philosopher Thomas Hobbes became one of the first scholars to comment on foragers, describing their lifestyle as “nasty, brutish, and short.” We now realize that his viewpoint was colored by ethnocentrism and, more specifically, eurocentrism and white supremacy. Hobbes, as well as many scholars that came after him, viewed Western societies as the pinnacle of social evolution and viewed less technologically advanced societies as deficient, antiquated, or primitive, a perspective that persisted well into the twentieth century.

In the 1960s, the anthropological perspective on foragers changed when Marshall Sahlins suggested that these communities were “the original affluent society.” He argued that foragers had an idyllic life, in which only a small percentage of the day was spent “working,” or acquiring resources, and most of the day was spent in leisure and socializing, leading to stronger community and family bonds.

Hunter-gatherers consume less energy per capita per year than any other group of human beings. Yet when you come to examine it, the original affluent society was none other than the hunter’s—in which all the people’s material wants were easily satisfied. To accept that hunters are affluent is therefore to recognize that the present human condition of man slaving to bridge the gap between his unlimited wants and his insufficient means is a tragedy of modern times.^[8]

Today anthropologists recognize that foraging, far from being primitive, is one of the most effective and dynamic subsistence systems humans have ever developed, yet Sahlins’ conception of the original affluent society is overly romantic. Foraging is a challenging lifestyle; some groups spend up to 70 hours per week collecting food. The amount of leisure time and relative comfort of the foraging lifestyle vary significantly based on differences in the availability of food and environmental conditions.^[9]

Contemporary studies of foraging also recognize that foragers have rarely lived in isolation. Throughout the world, foragers have lived near farming populations for hundreds or even thousands of years. Conflicts and competition for resources with non-foraging societies have characterized the foraging experience and foragers, with their relatively small population size and limited technology, have often been on the losing end of these confrontations. Government policies containing foragers to small “reservation” areas or forcing them to settle in towns have had catastrophic effects on foragers, as has the destruction through agricultural and industrial development of the ecosystems on which many groups once depended. A sad worldwide pattern of exploitation and marginalization is the reason that many foragers today live in dwindling communities in marginal ecological zones.^[10]

5.3.2 Pastoralism

“To us, a co-wife is something very good, because there is much work to do. When it rains … the village gets mucky. And it’s you who clears it out. It’s you who … looks after the cows. You do the milking … and your husband may have very many cows. That’s a lot of work… So Maasai aren’t jealous because of all this work.” – Maiyani, Maasai woman^[12]

Pastoralism is a subsistence system that relies on herds of domesticated livestock. Over half of the world’s pastoralists reside in Africa, but there are also large pastoralist populations in Central Asia, Tibet, and arctic Scandinavia and Siberia. The need to supply grazing fields and water for the livestock requires moving several times a year. For that reason, this subsistence system is sometimes referred to as nomadic pastoralism. In Africa, for instance, a nomadic lifestyle is an adaptation to the frequent periods of drought that characterize the region and put stress on the grazing pastures. Pastoralists may also follow a nomadic lifestyle for other reasons such as avoiding competition and conflict with neighbors or avoiding government restrictions.

Pastoralists can raise a range of different animals, although most often they raise herd animals such as cows, goats, sheep, and pigs. In some parts of South America, alpaca and llama have been domesticated for centuries to act as beasts of burden, much like camels, horses, and donkeys are used in Asia and Africa. Pastoralists who raise alpacas, donkeys, or camels, animals not typically considered food, demonstrate an important point about the pastoralist subsistence system. The goal of many pastoralists is not to produce animals to slaughter for meat, but instead to use other resources such as milk, which can be transformed into butter, yogurt, and cheese, or products like fur or wool, which can be sold. Even animal dung is useful as an alternate source of fuel and can be used as an architectural product to seal the roofs of houses. In some pastoral societies, milk and milk products comprise between 60 and 65 percent of the total caloric intake. However, very few, if any, pastoralist groups survive by eating only animal products. Trade with neighboring farming communities helps pastoralists obtain a more balanced diet and gives them access to grain and other items they do not produce on their own.

A community of animal herders has different labor requirements compared to a foraging community. Caring for large numbers of animals and processing their products requires a tremendous amount of work, chores that are nonexistent in foraging societies. For pastoralists, daily chores related to caring for livestock translate into a social world structured as much around the lives of animals as around the lives of people.

The Maasai, a society of east African pastoralists whose livelihood depends on cows, have been studied extensively by anthropologists. Among the Maasai, domestic life is focused almost entirely around tasks and challenges associated with managing the cattle herds. Like many pastoralist communities, the Maasai measure wealth and social status according to the number of animals a person owns. However, raising cattle requires so much work that no one has the ability to do these jobs entirely on his or her own. For the Maasai, the solution is to work together in family units organized around polygynous marriages. A household with multiple wives and large numbers of children will have more labor power available for raising animals.

As discussed previously, foragers tend to have little private property. Obtaining food from the natural environment and living a highly mobile lifestyle does not provide the right conditions for hoarding wealth, while the strong value on sharing present in foraging communities also limits wealth differences. Pastoralists, in contrast, have a great deal of personal property: most of it in the form of animals, a kind of “money on legs,” but also in the form of household objects and personal items like clothing or jewelry that pastoralists can keep more easily than foragers because they do not move as frequently.

Ownership of the grazing land, water supply, and other resources required for livestock is a trickier matter. Generally, these natural resources are treated as communal property shared by everyone in the society. Pastoralists may range over hundreds of miles throughout the year, so it would be highly impractical to “own” any particular plot of land or to try fencing it to exclude outsiders as is commonly done by agriculturalists. Sharing resources can lead to conflict, however, both within pastoralist societies and between pastoralists and their neighbors. In an influential essay, Tragedy of the Commons (1968), Garrett Hardin pointed out that people tend not to respect resources they do not own. For instance, pastoralists who have a personal interest in raising as many cattle of their own as possible may not be particularly motivated to preserve grass or water resources in the long term. Do pastoralists destroy the environments in which they live? Evidence from anthropological studies of pastoralist communities suggests that pastoralists do have rules that regulate use of land and other resources and that these restrictions are effective in conserving environmental resources.

The Maasai, for instance, have a complex land-management system that involves rotating pastures seasonally and geographically to preserve both grass and water. Research conducted in Kenya and Tanzania suggests that these grazing practices improve the health and biodiversity of the ecosystem because grazing cattle cut down the tall grasses and make habitats for warthogs, Thomson’s gazelle, and other species. In addition, the large swaths of community land managed by the Maasai stabilize and support the vast Serengeti ecosystem. Ecologists estimate that if this land were privately owned and its usage restricted, the population of wildebeest would be reduced by one-third. Since thousands of tourists visit the Serengeti each year to view wildlife, particularly the migration of the wildebeest, which is the largest mammal migration in the world, the Maasai’s communal land management is worth an estimated $83.5 million to the tourist economies of Kenya and Tanzania.^[15]

Despite the sophistication of their land and animal management techniques, pastoralists today face many pressures. The growth of the tourism industry in many countries has led to increased demand for private land ownership to support safari centers, wild game parks, and ecolodges. The steady growth of human populations and intensive agriculture has also led to the widespread encroachment of cities and farms into traditional pastoralist territories. Persistent drought, famine, and even civil war threaten some pastoralist groups, particularly in central Africa. Meanwhile, pastoralists continue to experience tense relationships with their agricultural neighbors as both groups compete for resources, disputes that are intensifying as global warming leads to more intense heat and drought in many world regions.

5.3.3 Horticulture

“Yams are persons with ears. If we charm, they hear.” – Alo, Trobriand Island farmer^[16]

Have you ever grown a garden in your backyard? How much time did you put into your garden? How much of your diet did the garden yield? People whose gardens supply the majority of their food are known as horticulturalists. Horticulture differs in three ways from other kinds of farming. First, horticulturalists move their farm fields periodically to use locations with the best growing conditions. For this reason, horticulture is sometimes known as shifting cultivation. Second, horticultural societies use limited mechanical technologies to farm, relying on physical labor from people and animals, like oxen that may be used to pull a plow, instead of mechanical farm equipment. Finally, horticulture differs from other kinds of farming in its scale and purpose. Most farmers in the United States sell their crops as a source of income, but in horticultural societies, crops are consumed by those who grow them or are shared with others in the community rather than sold for profit.

Horticultural societies are common around the world; this subsistence system feeds hundreds of thousands of people, primarily in tropical areas of south and central America, Southeast Asia, and Oceania. A vast array of horticultural crops may be grown by horticulturalists, and farmers use their specialized knowledge to select crops that have high yield compared to the amount of labor that must be invested to grow them. A good example is manioc, also known as cassava. Manioc can grow in a variety of tropical environments and has the distinct advantage of being able to remain in the ground for long periods without rotting. Compared to corn or wheat, which must be harvested within a particular window of time to avoid spoiling, manioc is flexible and easier to grow as well as to store or distribute to others. Bananas, plantains, rice, and yams are additional examples of popular horticultural crops. One thing all these plants have in common, though, is that they lack protein and other important nutrients. Horticultural societies must supplement their diets by raising animals such as pigs and chickens or by hunting and fishing.

Growing crops in the same location for several seasons leads to depletion of the nutrients in the soil as well as a concentration of insects and other pests and plant diseases. In agricultural systems like the one used in the United States, these problems are addressed through the use of fertilizers, pesticides, irrigation, and other technologies that can increase crop yields even in bad conditions. Horticulturalists respond to these problems by moving their farm fields to new locations. Often this means clearing a section of the forest to make room for a new garden, a task many horticulturalists accomplish by cutting down trees and setting controlled fires to burn away the undergrowth. This approach, sometimes referred to as “slash-and-burn,” sounds destructive and has often been criticized, but the ecological impact is complex. Once abandoned, farm fields immediately begin to return to a forested state; over time, the quality of the soil is renewed. Farmers often return after several years to reuse a former field, and this recycling of farmland reduces the amount of forest that is disturbed. While they may relocate their farm fields with regularity, horticulturalists tend not to move their residences, so they rotate through gardens located within walking distance of their homes.

Horticulturalists practice multi-cropping, growing a variety of different plants in gardens that are biodiverse. Growing several different crops reduces the risk of relying on one kind of food and allows for intercropping, mixing plants in ways that are advantageous. A well-known and ingenious example of intercropping is the practice of growing beans, corn, and squash together. Native American farmers in the pre-colonial period knew that together these plants, sometimes called “the three sisters,” were healthier than they were if grown separately. Rather than completely clearing farmland, horticulturalists often maintain some trees and even weeds around the garden as a habitat for predators that prey on garden pests. These practices, in addition to skillful rotation of the farmland itself, make horticultural gardens particularly resilient.

5.3.4 Agriculture

“The adoption of agriculture, supposedly our most decisive step toward a better life, was in many ways a catastrophe from which we have never recovered.”

– Jared Diamond ^[17]

Agriculture is defined as the cultivation of domesticated plants and animals using technologies such as irrigation, draft animals, mechanization, and inputs such as fertilizers and pesticides that allow for intensive and continuous use of land resources. About 10,000 years ago, human societies entered a period of rapid innovation in subsistence technologies that paved the way for the emergence of agriculture. The transition from foraging to farming has been described as the Neolithic Revolution. Neolithic means “new stone age,” a name referring to the very different looking stone tools produced during this time period. The Neolithic was characterized by an explosion of new technologies, not all of them made from stone, which were geared toward agricultural tasks, rather than hunting or processing gathered plant foods. These new tools included scythes for harvesting plants, and adzes or hoes for tilling the soil. These technological developments began to dramatically improve yields and allow human communities to support larger and larger numbers of people on food produced in less space. It is important to remember that the invention of agriculture was not necessarily an advance in efficiency because more work had to go in to producing more food. Instead, it was an intensification of horticultural strategies. As a subsistence system, agriculture is quite different from other ways of making a living, and the invention of agriculture had far-ranging effects on the development of human communities. In analyzing agriculture and its impacts, anthropologists focus on four important characteristics shared by agricultural communities.

The first characteristic of agriculture is reliance on a few staple crops, foods that form the backbone of the subsistence system. An example of a staple crop would be rice in China, or potatoes in Ireland. In agricultural societies, farmers generally grow a surplus of these staple crops, more than they need for their own tables, which are then sold for profit. The reliance on a single plant species, or mono-cropping, often leads to decreased dietary diversity and carries the risk of malnutrition compared to a more diverse diet. Other risks include crop failure associated with bad weather conditions or blight, leading to famine and malnutrition, conditions that are common in agricultural communities.

A second hallmark of agriculture is the link between intensive farming and a rapid increase in human population density. The archaeological record shows that human communities grew quickly around the time agriculture was developing, but this raises an interesting question. Did the availability of more food lead to increases in the human population? Or, did pressure to provide for a growing population spur humans to develop better farming techniques? This question has been debated for many years. Ester Boserup, who studied the emergence of agriculture, concluded that growth in human populations preceded the development of agriculture, forcing communities to develop innovations in technology. However, the improved productive capabilities of agriculture came at a cost. People were able to pro- duce more food with agriculture, but only by working harder and investing more in the maintenance of the land. The life of a farmer involved more daily hours of work compared to the lifestyle of a forager, so agricultural communities had an incentive to have larger families so that children could help with farm labor. However, the presence of more children also meant more mouths to feed, increasing the pressure to further expand agricultural production. In this way, agriculture and population growth became a cycle.

A third characteristic of agriculture is the development of a division of labor, a system in which individuals in a society begin to specialize in certain roles or tasks. Building houses, for instance, becomes a full-time job separate from farming. The division of labor was possible because higher yields from agriculture meant that the quest for food no longer required everyone’s participation. This feature of agriculture is what has allowed nonagricultural occupations such as scientists, religious specialists, politicians, lawyers, and academics to emerge and flourish.

The emergence of specialized occupations and an agricultural system geared toward producing surplus rather than subsistence changed the economics of human communities. The final characteristic of agriculture is its tendency to create wealth differences. For anthropologists, agriculture is a critical factor explaining the origins of social class and wealth inequality. The more complex an economic system becomes, the more opportunities individuals or factions within the society have to manipulate the economy for their own benefit. Who do you suppose provided the bulk of the labor power needed in early agricultural communities? Elites found ways to pass this burden to others. Agricultural societies were among the first to utilize enslaved and indentured labor.

Although the development of agriculture is generally regarded as a significant technological achievement that made our contemporary way of life possible, agriculture can also be viewed as a more ominous development that forced us to invest more time and labor in our food supply while yielding a lower quality of life.^[18]
