Local food

Local food is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Local food rather than just read about it. In short: Local food is food that is produced within a short distance of where it is consumed, often accompanied by a social structure and supply chain different from the large-scale supermarket system. Local food (or locavore) movements aim to connect food producers and consumers in the same geographic region, to develop more self-reliant and resilient food networks, improve local economies, or to affect the health, environm…

Key takeaways

  • Local food belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Local food to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Local food from memory before moving on to harder problems.

Reference excerpt

Local food is food that is produced within a short distance of where it is consumed, often accompanied by a social structure and supply chain different from the large-scale supermarket system. Local food (or locavore) movements aim to connect food producers and consumers in the same geographic region, to develop more self-reliant and resilient food networks, improve local economies, or to affect the health, environment, community, or society of a particular place. The term has also been extended to include not only the geographic location of supplier and consumer but can also be "defined in terms of social and supply chain characteristics." For example, local food initiatives often promote sustainable and organic farming practices, although these are not explicitly related to the geographic proximity of producer and consumer. Local food represents an alternative to the global food model, which often sees food traveling long distances before it reaches the consumer.

History In the US, the local food movement has been traced to the Agricultural Adjustment Act of 1933, which spawned agricultural subsidies and price supports. The contemporary American movement can be traced back to proposed resolutions to the Society for Nutrition Education's 1981 guidelines. In 1994, Chicago pop culture made local food a trend in the Midwest. These largely unsuccessful resolutions encouraged increased local production to slow farmland loss. The program described "sustainable diets" — a term then new to the American public. At the time, the resolutions were met with strong criticism from pro-business institutions, but have had a strong resurgence of backing since 2000. In 2008, the United States farm bill was revised to emphasise nutrition: "it provides low-income seniors with vouchers for use at local produce markets, and it added more than $1 billion to the fresh fruit and vegetable program, which serves healthy snacks to 3 million low-income children in schools".

Definitions

No single definition of local food systems exists. The geographic distances between production and consumption varies within the movement. However, the general public recognizes that "local" describes the marketing arrangement (e.g. farmers selling directly to consumers at regional farmers' markets or to schools). Definitions can be based on political or geographic boundaries, or on food miles. The American Food, Conservation, and Energy Act of 2008 states that:

(I) the locality or region in which the final product is marketed, so that the total distance that the product is transported is less than 400 miles from the origin of the product; or(II) the State in which the product is produced. In May 2010, the USDA acknowledged this definition in an informational leaflet. State definitions of "local" can be included in laws, statutes, regulations, or program materials, however few state laws explicitly define "local" food. Most states use "local" (or similar words like "native") in food procurement and marketing policies to mean that the food was produced within that state. The concept of "local" is also seen in terms of ecology, where food production is considered from the perspective of a basic ecological unit defined by its climate, soil, watershed, species and local agrisystems, a unit also called an ecoregion or a foodshed. Similar to watersheds, foodsheds follow the process of where food comes from and where it ends up.

Contemporary local food markets

In America, local food sales were worth $1.2 billion in 2007, more than doubled from $551 million in 1997. There were 5,274 farmers' markets in 2009, compared to 2,756 in 1998. In 2005, there were 1,144 community-supported agriculture organizations (CSAs). There were 2,095 farm to school programs in 2009. Using metrics such as these, a Vermont-based farm and food advocacy organization, Strolling of the Heifers, publishes the annual Locavore Index, a ranking of the 50 US states plus Puerto Rico and the District of Columbia. In the 2016 Index, the three top-ranking states were Vermont, Maine and Oregon, while the three lowest-ranking states were Nevada, Texas and Florida. Websites now exist that aim to connect people to local food growers. They often include a map where fruit and vegetable growers can pinpoint their location and advertise their produce. Supermarket chains also participate in the local food scene. In 2008 Walmart announced plans to invest $400 million in locally grown produce. Other chains, like Wegman's (a 71-store chain across the northeast), have long cooperated with the local food movement. A recent study led by economist Miguel Gomez found that the supermarket supply chain often did much better in terms of food miles and fuel consumption for each pound compared to farmers markets.

Local food campaigns Local food campaigns have been successful in supporting small local farmers. After declining for more than a century, the number of small farms increased 20% in the six years to 2008, to 1.2 million, according to the Agriculture Department (USDA). Launched in 2009, North Carolina's 10% local food campaign is aimed at stimulating economic development, creating jobs and promoting the state's agricultural offerings. The campaign is a partnership between The Center for Environmental Farming Systems (CEFS), with support from N.C. Cooperative Extension and the Golden LEAF Foundation. In 2017, a campaign was started in Virginia by the Common Grains Alliance mirroring many of the efforts of the North Carolina campaign.

Motivations for eating locally Motivations for eating local food include healthier food, environmental benefits, and economic or community benefits. Many local farmers, whom locavores turn to for their source of food, use the crop rotation method when producing their organic crops. This method not only aids in reducing the use of pesticides and pollutants, but also keeps the soil in good condition rather than depleting it. Locavores seek out farmers close to where they live, and this significantly reduces the amount of travel time required for food to get from farm to table. Reducing the travel time makes it possible to transport the crops while they are still fresh, without using chemical preservatives. The combination of local farming techniques and short travel distances makes the food consumed more likely to be fresh, an added benefit.

Worked examples

Example 1 — a first encounter with Local food

Start with the simplest possible case. Write down what Local food claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Local food before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Local food ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Local food

In research
Local food appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Local food in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Local food is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ecology terminology, Food politics, Food security, so understanding it makes those chapters shorter.
In everyday life
Look for Local food outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
