The Geography of Food is a field of human geography
Human geography
Human geography is one of the two major sub-fields of the discipline of geography. Human geography is the study of the world, its people, communities, and cultures. Human geography differs from physical geography mainly in that it has a greater focus on studying human activities and is more...

Food
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals...

History

Spatial variations in food production and consumption practices have been noted for thousands of years. In fact, Plato commented on the destructive nature of agriculture when he referred to the soil erosion from the mountainsides surrounding Athens (3) (p. 61). The study of food has not been confined to a single discipline, and has received attention from a huge range of diverse sources.

Modern geographers initially focused on food as an economic activity, especially in terms of agricultural geography. It was not until recently that geographers have turned their attention to food in a wider sense: "The emergence of an agro-food geography that seeks to examine issues along the food chain or within systems of food provision derives, in part, from the strengthening of political economy approaches in the 1980s" (Winter 2004).

Overlapping areas of study

Because food is a bridge between the natural and the social world, it has received attention from both the physical sciences and the social sciences
Social sciences
Social science is the field of study concerned with society. "Social science" is commonly used as an umbrella term to refer to a plurality of fields outside of the natural sciences usually exclusive of the administrative or managerial sciences...

. Some of the earliest numerical data about food production come from bureaucratic sources linked to the ancient civilizations of Ancient Egypt and the Roman Empire (3). Traders have also been influential in documenting food networks. Early Indian mapped the location of trading posts associated with food production nodes.

Thomas Malthus famously stated that food output could only expand arithmetically (in proportion with the extension of farmland) while population could increase geometrically, leading to a 'population bomb' or a Malthusian catastrophe

A Malthusian catastrophe was originally foreseen to be a forced return to subsistence-level conditions once population growth had outpaced agricultural production...

. His theory was also given a spatial element when he predicted the Irish potato famine (though there was enough non-potato based food produced in Ireland at the time the potato crop failed, the British, who controlled Ireland, sold the food abroad).

Since the industrial revolution

The Industrial Revolution was a period from the 18th to the 19th century where major changes in agriculture, manufacturing, mining, transportation, and technology had a profound effect on the social, economic and cultural conditions of the times...

, the study of food has been increasingly formalized, often taking an explicit spatial dimension. Food featured greatly in economics, experimental agriculture, political economy and travel literature. It was still not studied from an explicitly geographical perspective though until the 20th century.

Food Production

Food production was the first element of food to receive extensive attention from geographers.

Food Consumption

The huge variation in diet and consumption practices on global and regional scales became the focus of geographers and economists with the vastly expanding population and widely publicized famines of the 1960s. Differences in the caloric intake of food and the composition of diet was estimated and mapped for many countries from the 1960s onward.

DCs consume more food than LDCs in the past years. However, in the recent years, the LDCs have been increasing its food consumption. Besides, DCs have been reported to have a food consumption level greater than satisfactory level ever since 1960s while the LDCs' food consumption has been below this level even until the first decade of 21st century.

There are many factors contributing to this difference. And these factors are categorized into two main areas—food availability and food accessibility.

Since the farmers in DCs are able to produce more food with the application of proper agricultural system as well as the usages of machinery and modern irrigation, there is more than enough food available for the farmers in DCs. In contrast, such high level of food production is absent in LDCs which leads to food insufficiency in LDCs.

However, globalization allows international trading of food and LDCs have benefited from this progress in the world as they are able to purchase food from various sources with the international aid.

Moreover, advances in agrotechnology has also increased food production in LDCs.

Power Networks

Power networks in food is a relatively new field in the study of food. It was kick-started by Richard Le Heron with his book Globalized Agriculture: Political Choice (Pergamon, 1993). Since then, a large and rapidly growing literature of the geographies emerged in some of the human geography journals.
