Verified for the 2025 AP Human Geography examLast Updated on June 18, 2024

The nature of modern agriculture and our food-production techniques are rapidly changing, which will be a main focus in this section. We will look at the debates surrounding the use of agricultural innovations, what influences food production and consumption, the challenges of providing food for all, and economic factors that affect food-production. 

Debates Surrounding Agricultural Innovations

*These innovations have raised questions about their sustainability, soil and water usage, effect on biodiversity, and extensive use of chemicals. 

Biotechnology

Definition

Biotechnology is the use of living organisms or their products to develop or make products or technologies. Biotechnology has a wide range of applications, including agriculture, medicine, environmental management, and industry.

In agriculture, biotechnology is used to develop crops that are resistant to pests and diseases, tolerate drought and other environmental stresses, and have improved nutritional content. This can help to increase crop yields and reduce the need for chemical inputs, such as pesticides and fertilizers.

In medicine, biotechnology is used to develop new drugs, diagnostic tests, and therapies. This can help to improve the treatment of diseases and improve public health.

In environmental management, biotechnology is used to develop technologies that help to clean up contaminated sites, reduce pollution, and conserve natural resources.

In industry, biotechnology is used to produce a variety of products, such as biofuels, bioplastics, and industrial enzymes.

Some examples of biotechnology include genetic engineering, fermentation, and tissue culture. Biotechnology has the potential to revolutionize many different fields, but it is also a controversial area, and there are concerns about the safety and ethical implications of some biotechnology applications.

Arguments for:

  • More efficient crop production
  • Prolonged freshness of products
  • Can design/modify organisms for specific purposes

Arguments against:

  • Consuming large amounts of GMO foods could reduce the effectiveness of antibiotics and affect the ecological balance of agriculture
  • Genetically modified plants and animals could interbreed and contaminate food supplies

GMOs

Definition

GMOs, or genetically modified organisms, are living organisms that have had their DNA modified using biotechnology techniques. The genetic material of a GMO is altered in a way that does not occur naturally, usually by adding or removing specific genes.

GMOs are used in a variety of applications, including agriculture, medicine, and industry. In agriculture, GMOs are used to develop crops that are resistant to pests and diseases, tolerate environmental stresses, and have improved nutritional content. This can help to increase crop yields and reduce the need for chemical inputs, such as pesticides and fertilizers.

GMOs are controversial, and there are ongoing debates about their safety, environmental impacts, and ethical implications. Some people are concerned about the potential risks of GMOs, such as the potential for unintended consequences and the potential for harm to human health or the environment. Others argue that GMOs can have many benefits, such as increasing food security and reducing the environmental impact of agriculture.

The use of GMOs is regulated by governments around the world, and there are labeling requirements for food products that contain GMOs in some countries. However, there are different approaches to regulating GMOs, and the regulations vary by country.

Arguments for:

  • Higher yields
  • More nutrient dense varieties
  • Resistant to pests
  • Tolerant to droughts
  • Tolerant to herbicides

Arguments against:

Environmental hazards 

  • Unwanted gene transfer to other organisms
  • Unintended harm to other organisms

Human health risk 

  • Unknown or unintended health effects
  • Economic concerns

Patents by agrichemical companies 

  • GMOs are more expensive to produce and take longer to bring into the market

Aquaculture

Definition

Aquaculture is the farming of aquatic organisms, such as fish, shellfish, and seaweed. It is an important source of food and other products, such as fishmeal, fish oil, and pearls.

Aquaculture can be practiced in a variety of aquatic environments, including fresh water, salt water, and brackish water. There are many different species of aquatic organisms that are farmed, including finfish, shellfish, seaweed, and algae.

Aquaculture can be carried out in a variety of systems, including ponds, tanks, cages, and raceways. It can be practiced on a small scale, such as in backyard ponds, or on a large scale, such as in offshore cages.

Aquaculture is an important source of food and other products, and it can help to meet the growing demand for seafood. However, it is also a controversial industry, and there are concerns about the environmental impacts of aquaculture, such as pollution, habitat destruction, and the spread of diseases and parasites. There are also concerns about the welfare of farmed aquatic animals and the use of wild fish as feed in some aquaculture systems.

Arguments for:

  • Fish and marine plants can be used to rebuild species populations
  • Plants grown in aquaculture provide material that can be used for pharmaceutical nutritional, and biotechnology purposes
  • Could be used for treating sewage and wastewater (by using fish like prawns and carp that gain nutrients from waste)

Arguments against:

  • Can lead to overfishing
  • Certain fish species can become extinct
  • Marine ecosystems can be affecting by upsetting the food chain
  • Can pollute water systems (due to large concentrations of fish)
  • Can change the landscape for marine life
  • Expensive practice

Influences on Food Production and Consumption

What we choose to eat greatly affects food production and consumption patterns, and there are plenty of “movements” related to individual food choices that influence these patterns, such as urban farming, community-supported agriculture (CSA), organic farming, value added specialty crops, fair trade, local-food movements, and dietary shifts. 

  • Community-Supported Agriculture (CSA)
    • A network or association of individuals who have agreed to support one or more local farms
    • Both growers and consumers share the upsides and downsides that come with food production
  • Organic Farming - No genetically modified organisms - No artificial/harsh chemicals (pesticides, antibiotics, fertilizers, synthetic hormones) - Less costly to grow - Has little effect on the production of staple foods - Questionable standards and sustainability - Prices out smaller farms because subsidies favor larger farms with more diverse ecosystems (since chemicals can’t be used)
  • Value-added Specialty Crops
    • These have something “special” in them that makes them unique and priced higher
      • Something different in the production of the product that “enhances its value”
    • Examples:
      • Organically produced (oftentimes seen as “better,” so people are willing to purchase it at a higher price)
      • Jams (these are special because fruits are changed into something delicious in production)
      • Cotton-candy grapes (the name itself says specialty, and you don’t find them everywhere either! side note- you must try these when they’re in season!)
  • Fair Trade
    • Promotes sustainability
    • Fair everything! (Emphasizes small business)
      • Fair worker wages
      • Permits union organizing
      • Must comply with minimum environmental and safety hazards
    • When you see “fair trade” on product labels, this means that the product producers are getting a fair price for their goods
  • Local Food Movements
    • Local farmers markets
      • Food is the main attraction, but they also provide a sense of community and are generally an enjoyable, fun experience

Food for All (What’s wrong with this?)

*You should know the challenges of trying to feed an entire world’s worth of population (7 billion people is a lot!) 

  • Lack of/Unequal Food Access
    • Food insecurity
      • Plenty of children and families around the world are food insecure
      • It means sparse physical, social, or economic access to healthy food needed to meet dietary standards
    • Food deserts
      • Areas with very little access to (or even no access to) nutritious, affordable food such as fresh fruits and vegetables
      • *Know this: There are areas only surrounded by fast food restaurants and run-down gas stations -> how are people in poverty supposed to stay healthy, let alone afford this?!
  • Issues with Distribution Systems
    • Certain areas may receive more product than others, which is especially unfavorable to those living in remote, isolated regions
  • Unpredictable/Unfavorable Weather Conditions
    • Food may not reach these areas as readily
    • Farmlands may be located very far away, making it difficult for regions located in harsh climates to get access to fresh produce
  • Suburbanization
    • Results in loss of land, and as a result, decreased farmland and crop production

What Economic Processes Affect Food-Production?

There are several economic processes that can affect food production, including:

  1. Supply and demand: The basic economic principle of supply and demand can affect the production of food. If there is a high demand for a particular type of food and a low supply, the price of that food will tend to increase, which can incentivize producers to increase production. On the other hand, if there is a low demand and a high supply, the price will tend to decrease, which can discourage producers from producing that food.
  2. Production costs: The costs of producing food, such as labor, land, and inputs, can also affect food production. If the costs of production are high, it may not be profitable for producers to grow certain types of food, which can lead to a reduction in production.
  3. Government policies: Government policies, such as subsidies, tariffs, and regulations, can also affect food production. For example, subsidies can make it more profitable for producers to grow certain types of food, while tariffs can make it more expensive to import food from other countries, which can encourage domestic production.
  4. Market conditions: Market conditions, such as competition, prices of related goods, and consumer preferences, can also affect food production. For example, if there is strong competition among producers, it may be necessary to reduce prices in order to sell goods, which can affect profitability.
  5. Natural disasters: Natural disasters, such as droughts, floods, and hurricanes, can also affect food production. These disasters can damage crops and livestock and disrupt supply chains, which can lead to a reduction in food production.

To put it simply, you should know that the way food is produced is largely determined by the location of food-processing facilities, economies of scale, distribution systems, and government policies.

Community-Supported Agriculture (CSA): Community-Supported Agriculture (CSA) is a farming model where consumers buy shares of a farm's harvest in advance, thus providing farmers with capital at the start of the growing season. This arrangement fosters a direct relationship between consumers and farmers, allowing people to receive fresh, local produce while supporting sustainable agricultural practices. It addresses several challenges in contemporary agriculture by promoting local food systems and reducing reliance on large-scale industrial farming.
Fair Trade: Fair Trade is a global movement aimed at ensuring that producers in developing countries receive fair wages and working conditions for their goods, particularly in agriculture. This approach challenges traditional trade practices that often exploit farmers and workers, promoting sustainable practices and economic equity. By prioritizing ethical standards, Fair Trade seeks to empower marginalized communities while enhancing their economic prospects and fostering environmental stewardship.
Fermentation: Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol using microorganisms like yeast or bacteria in the absence of oxygen. This process is crucial in food production, especially in creating products like bread, beer, and yogurt, which are significant in contemporary agricultural practices and food systems.
Food Insecurity: Food insecurity refers to the lack of consistent access to enough food for an active, healthy life. This condition can arise from various factors, including economic hardship, social inequality, and geographical disparities, which often intersect with agricultural practices and population distribution. Addressing food insecurity requires understanding how these elements interact and affect communities at different scales.
Food Deserts: Food deserts are areas where residents have limited access to affordable and nutritious food, often due to a lack of grocery stores or healthy food retailers within a convenient traveling distance. This phenomenon is linked to various socio-economic factors, including income levels, urban planning, and agricultural practices that impact food availability and equity.
Genetic Engineering: Genetic engineering is a scientific process that involves modifying the genetic material of an organism to alter its characteristics. This technique allows scientists to introduce new traits, enhance existing traits, or remove undesirable traits in plants, animals, and microorganisms, making it a powerful tool in addressing challenges faced in contemporary agriculture.
GMOs (Genetically Modified Organisms): GMOs, or Genetically Modified Organisms, are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering. This technology allows for the introduction of new traits or characteristics that do not occur naturally in the species, enabling advancements in agriculture, such as increased yield and pest resistance. However, the use of GMOs has sparked significant debate regarding food safety, environmental impact, and ethical considerations in contemporary agriculture.

This approach incorporates scientific research, machinery, and innovative techniques to improve crop yields, manage resources effectively, and respond to the growing global demand for food, while also addressing environmental concerns and agricultural challenges.
Organic Farming: Organic farming is an agricultural practice that focuses on growing crops and raising livestock without the use of synthetic fertilizers, pesticides, or genetically modified organisms (GMOs). This method emphasizes sustainability, biodiversity, and environmental health, and it seeks to create a balanced ecosystem that promotes natural processes rather than relying on artificial inputs.
Production Costs in Food Production: Production costs in food production refer to the expenses incurred in the process of growing, harvesting, processing, and distributing food products. These costs can significantly influence agricultural practices and decisions, impacting everything from crop selection to market pricing. Understanding production costs is essential for farmers and agricultural businesses to remain competitive and sustainable in an ever-evolving industry.
Suburbanization: Suburbanization is the process by which people move from urban areas to the outskirts or suburbs, often resulting in the growth of residential communities outside city centers. This trend can lead to changes in land use, economic structures, and social dynamics, reflecting broader patterns of migration and development within a society.
Supply and Demand in Food Production: Supply and demand in food production refers to the relationship between the availability of food products (supply) and the desire of consumers to purchase these products (demand). This dynamic is crucial in determining food prices and availability in the market. When demand exceeds supply, prices tend to rise, leading producers to increase output, while an oversupply with low demand can lead to price drops, impacting farmer incomes and food security.
Tissue Culture: Tissue culture is a technique used in agriculture and plant science to grow plant cells, tissues, or organs in a controlled environment on a nutrient medium. This method allows for the rapid propagation of plants and the production of genetically identical offspring, making it crucial for addressing challenges in contemporary agriculture such as crop diseases and genetic diversity.
Urban Farming: Urban farming is the practice of cultivating, processing, and distributing food in or around urban areas, often utilizing small plots of land, rooftops, and community gardens. This method addresses food security, promotes local economies, and enhances green spaces in densely populated cities, highlighting the connection between agriculture and urban sustainability.
Value Added Specialty Crops: Value added specialty crops are agricultural products that are enhanced through processing, packaging, or marketing to increase their economic value beyond the raw product. These crops often include unique or niche items like organic fruits, gourmet vegetables, or artisanal products that cater to specific consumer demands. By adding value, farmers can improve their profit margins and support local economies while facing the challenges of contemporary agriculture.
