Food system

The term food system is used frequently in discussions about nutrition, food, health, community economic development and agriculture. A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, and disposal of food and food-related items. It also includes the inputs needed and outputs generated at each of these steps. A food system operates within and is influenced by social, political, economic and environmental contexts. It also requires human resources that provide labor, research and education. Food systems are either conventional  or alternative according to their model of food lifespan from origin to plate.

According to the IPCC, the global food system, including all of the various industries involved in sustainable and conventional food systems, provide employment for 1 billion people. This global food system is facing a number of challenges created by impeding global food security issues created by climate change and non-climate change stresses on the system. Between 21-37% of total greenhouse gas emissions are attributable to the global food system.

Conventional food systems
Conventional food systems operate on economies of scale. These food systems are geared towards a production model that requires maximizing efficiency in order to lower consumer costs and increase overall production, and they utilize economic models such as vertical integration, economic specialization, and global trade.

The term “conventional” when describing food systems is in large part due to comparisons made to it by proponents of other food systems, collectively known as alternative food systems.

History of conventional food systems

The development of food systems can be traced back to the origins of in-situ agriculture and the production of food surpluses. These surpluses enabled the development of settled areas and contributed to the development of ancient civilizations, particularly those in the Fertile Crescent. The system of trade associated with the exchange of foodstuffs also emerged in East Asia, North America, South America, and Subsaharan Africa with common commodities of exchange such as salt, spices, fish, grains, etc. Through events in world history such as the conquests of Alexander the Great, the Crusades, the expansion of Islam, the journeys of Marco Polo, and the exploration and colonization of the Americas by Europeans led to the introduction and redistribution of new foods to the world at large, and food systems began to intermingle on a global scale. After World War II, the advent of industrialized agriculture and more robust global trade mechanisms have evolved into the models of food production, presentation, delivery, and disposal that characterizes conventional food systems today.

Impacts of conventional food systems

Lower food costs and greater food variety can be directly attributed to the evolution of conventional food systems. Agronomic efficiency is driven by the necessity to constantly lower production expenses, and those savings can then be passed on to the consumer. Also, the advent of industrial agriculture and the infrastructure built around conventional food systems has enabled the world population to expand beyond the "Malthusian catastrophe" limitations.According to the IPCC, food supply per capita has increased by more than 30% since 1961.

However, conventional food systems are largely based on the availability of inexpensive fossil fuels, which is necessary for mechanized agriculture, the manufacture or collection of chemical fertilizers, the processing of food products, and the packaging of the foods. The increase in availability of food since 1961 has largely been driven by an 800% increase in use of nitrogen fertilizers (which are fossil fuel dependent) and high water usage (an increase of over 100% since 1961). 

The impacts of these resource intense processes are many a varied: food processing began when the number of consumers started growing rapidly. The demand for cheap and efficient calories climbed resulting in nutrition decline; and industrialized agriculture, due to its reliance on economies of scale to reduce production costs, often leads to the compromising of local, regional, or even global ecosystems through fertilizer runoff, nonpoint source pollution, and greenhouse gas emission. 

The need to reduce production costs in an increasingly global market can cause production of foods to be moved to areas where economic costs (labor, taxes, etc.) are lower or environmental regulations are more lax, which are usually further from consumer markets. For example, the majority of salmon sold in the United States is raised off the coast of Chile, due in large part to less stringent Chilean standards regarding fish feed and regardless of the fact that salmon are not indigenous in Chilean coastal waters. The globalization of food production can result in the loss of traditional food systems in less developed countries, and have negative impacts on the population health, ecosystems, and cultures in those countries. As a result of these forces, 2018 estimates suggest that 821 million people are currently undernurished, and 2 billion adults are overweight and obese.

Alternative food systems

Alternative food systems are those that fall outside the scope of conventional agriculture, typically in order to create sustainable food systems.

Local food systems

Local food systems are networks of food production and consumption that aim to be geographically and economically accessible and direct. They contrast to industrial food systems by operating with reduced food transportation and more direct marketing, leading to fewer people between the farmer and the consumer. As a result, relationships that are developed in local food systems emerge from face-to-face interactions, potentially leading to a stronger sense of trust and social connectedness between actors. In addition to this, consumers can also encourage farmers to be environmentally friendly by teaching them about practices such as organic farming. As a result, some scholars suggest that local food systems are a good way to revitalize a community. The decreased distance of food transportation has also been promoted for its environmental benefits. Also, farmers can enjoy a better quality of life because producing healthier food will allow them to be paid more, and not live under the poverty line.

Both proponents and critics of local food systems warn that they can lead to narrow inward-looking attitudes or ‘local food patriotism’, and that price premiums and local food cultures can be elitist and exclusive.

Examples of local food systems include community-supported agriculture, farmers markets and farm to school programs. They have been associated with the 100 Mile Diet and Low Carbon Diet, as well as the food sovereignty movement and slow food movement. Various forms of urban agriculture locate food production in densely populated areas not traditionally associated with farming. Garden sharing, where urban and suburban homeowners offer land access to food growers in exchange for a share of the harvest, is a relatively new trend, at the extreme end of direct local food production.

Organic food systems

Organic food systems are characterized by a reduced dependence on chemical inputs and an increased concern for transparency and information. Organic produce is grown without the chemical pesticides and fertilizers of industrial food systems, and livestock is reared without the use of antibiotics or growth hormones. The reduced inputs of organic agriculture can also lead to a greater reliance on local knowledge, creating a stronger knowledge community amongst farmers. The transparency of food information is vital for organic food systems as a means through which consumers are able to identify organic food. As a result, a variety of certification bodies have emerged in organic food systems that set the standards for organic identification. Organic agriculture is promoted for the ecological benefits of reduced chemical application, the health benefits of lower chemical consumption, the economic benefits that accrue to farmers through a price premium, and the social benefits of increased transparency in the food system.

Like local food systems, organic food systems have been criticized for being elitist and inaccessible. Critics have also suggested that organic agriculture has been conventionalized such that it mimics industrial food systems while using pesticides and fertilizers that are organically derived

Cooperatives in food systems

Cooperatives can exist both at the farmer end of food production and the consumer end. Farming cooperatives refer to arrangements where farmers pool resources, either to cultivate their crops or get their crops to market. Consumer cooperatives often refer to food cooperatives where members buy a share in the store. Co-operative grocery stores, unlike corporate grocery stores, are socially owned and thus surpluses cannot be taken from the store as profit. As a result, food co-ops do not work for profit, potentially keeping prices more cost representative. Other forms of cooperatives that have developed more recently include community-supported agriculture, where community members buy a share in a farm’s harvest, and may also be engaged in farm labour, operating at both the consumer and producer end of food systems. Garden sharing pairs individual landowners and food growers, while variations on this approach organize groups of food gardeners for mutual assistance.

The benefits of cooperatives are largely in the redistribution of risk and responsibility. For farming cooperatives that share resources, the burden of investment is disbursed to all members, rather than being concentrated in a single individual. A criticism of cooperatives is that reduced competition can reduce efficiency

Fair Trade

Fair trade has emerged in global food systems to create a greater balance between the price of food and the cost of producing it. It is defined largely by more direct trading systems whereby producers have greater control over the conditions of trade and garner a greater fraction of the sale price. The main goal of Fair Trade is to "change international commercial
relations in such a way that disadvantaged producers can increase their control over their own future, have a fair and just return for their work, continuity of income and decent working and living conditions through sustainable development"  Like organic food systems, fair trade relies on transparency and the flow of information. Well-known examples of fair trade commodities are coffee and cocoa.

Effects of climate change 

The IPCC Special Report on Climate Change and Land describes the current global food system as potentially having major food security risks due to changes created by climate change, including changing local weather conditions, socioeconomic effects of climate change, vulnerability of certain types of agriculture (such as pastoral) and changes in diets due to availability. The foodsystem is one of the largest sources of greenhouse gas emissions, attributable for between 21-37% of the global emissions. 

Despite these challenges and the food system's central role in climate change, the IPCC special report committee reported that the food system could be adapted to reduce greenhouse gas emissions impacts and food security concerns could be addressed while shifting towards a sustainable diet.

Transparency

Transparency within food systems refers to full disclosure of information about rules, procedures and practices at all levels within a food production and supply chain. Transparency ensures that consumers have detailed information about production of a given food item. Traceability, by contrast, is the ability to trace to their origins all components in a food production and marketing chain, whether processed or unprocessed (e.g., meat, vegetables) foods. Concerns about transparency and traceability have been heightened with food safety scares such as bovine spongiform encephalopathy (BSE) and Escherichia coli (E. coli), but do not exclusively refer to food safety. Transparency is also important in identifying foods that possess extrinsic qualities that do not affect the nature of the food per se, but affect its production, such as animal welfare, social justice issues and environmental concerns.

One of the primary ways transparency is achieved is through certification and/or use of food labels. In the United States, some certification originates in the public sector, such as the United States Department of Agriculture (USDA) Organic label. Others have their origin in private sector  certification (e.g., Humanely Raised, Certified Humane). There are also labels which do not rely on certification, such as the USDA's Country of Origin Label (COOL).

Participation in local food systems such as Community Supported Agriculture (CSA), Farmers Markets, food cooperatives and farmer cooperatives also enhances transparency, and there are diverse programs promoting purchase of locally grown and marketed foods.
