    “We can indeed eliminate the scourge of hunger in our lifetime. We must be the Zero Hunger generation.” – José Graziano da Silva, Director General of the Food and Agricultural Organization of the United Nations [26]

    Despite agriculture’s tremendous productivity, food shortages, malnutrition, and famines are common around the world. How can this be? Many people assume that the world’s agricultural systems are not capable of producing enough food for everyone, but this is incorrect. Evidence from agricultural research demonstrates that there is enough worldwide agricultural capacity to feed everyone on the planet.[27] The problem is that this capacity is unevenly distributed. Some countries produce much more food than they need, and others much less. In addition, distribution systems are inefficient and much food is lost to waste or spoilage. It is also true that in an agricultural economy food costs money, and worldwide many people who are starving or undernourished lack food because they cannot pay for it, not because food itself is unavailable.

    Let’s return for a moment to the concept of meals and where our food actually comes from. Walking down the aisles of our local grocery store, we are surrounded by products that come from far away: apples from Chile, coffee from Guatemala, beans from India. This is evidence that our economy is organized around what anthropologists refer to as a world system, a complex web through which goods circulate around the globe. In the world system, complex chains of distribution separate the producers of goods from the consumers. Agricultural products travel long distances from their points of origin to reach consumers in the grocery store, passing through many hands along the way. The series of steps a food like apples or coffee takes from the field to the store is known as a commodity chain.

    Definition: world system

    A complex economic system through which goods circulate around the globe. The world system for food is characterized by a separation of the producers of goods from the consumers.

    Definition: commodity chain

    The series of steps a food takes from location where it is produced to the store where it is sold to consumers.

    Figure \(\PageIndex{1}\): Links in the Commodity Chain for Coffee: As the coffee changes hands from the growers, to the exporters, to the importers, and then to the retail distributors, the value of the coffee increases. Consider the differences in wage between these workers.

    The commodity chain for agricultural products begins in the farms where plant and animal foods are produced. Farmers generally do not sell their produce directly to consumers, but instead sell to large food processors that refine the food into a more usable form. Coffee beans, for instance, must be roasted before they can be sold. Following processing, food moves to wholesalers who will package it for sale to retail establishments like grocery stores. As foods move through the commodity chain, they become more valuable. Coffee beans harvested fresh from the field are worth $1.40 per pound to the farmer, but sell for $10–$20 at Starbucks.[28]

    The fact that food is more valuable at the end of the commodity chain than at the beginning has several consequences for human communities. The most obvious of these is the reality that farming is not a particularly lucrative occupation, particularly for small-scale farmers in developing countries. Though their labor makes profit for others, these farmers see the lowest financial returns. Another effect of global commodity chains is that food moves very far from its point of origin. For wealthy people, this means having access to a variety of foods in the grocery store, including things like strawberries or mangos in the middle of winter, but in order to serve markets in wealthy countries, food is diverted away from the locales where it is grown. When quinoa, a high-protein grain grown in Bolivia, became popular with health enthusiasts in wealthy countries, the price of this food more than tripled. Local populations began to export their quinoa crop rather than eating it, replacing this nutritious traditional food with white bread and Coca-Cola, which were much cheaper, but contributed to increased rates of obesity and diabetes.[29] The global travels of the food supply have also affected social relations that were once strengthened by participation in food growing and sharing. Distance and competition have replaced these communal experiences. Many people yearn for more connection with their food, a sentiment that fuels things like “foodie culture,” farm-to-table restaurants, and farmer’s markets.


    This chapter began with a consideration of meals, but revealed that each individual meal is part of a diet generated through a particular subsistence system. Many of our daily experiences, including our attitudes, skills, and relationships with others, are influenced by our subsistence system. Knowing that the Earth has been transformed for thousands of years by human subsistence activities, we must also consider the ways in which our future will be shaped by the present. Are we managing our resources in a sustainable way? How will we continue to feed growing populations in the future? Think about it next time you sit down to eat a meal.
