Study Notes
Artificial Selection
- Artificial selection is how humans breed organisms with desirable traits.
- Many domesticated plants and animals have evolved through artificial selection.
Origins of Traditional Agriculture
- Traditional agriculture began around 10,000 years ago.
- Evidence suggests independent domestication of plants in regions like Mesopotamia, the Indus Valley, China, and Mesoamerica.
- Traditional methods use low-tech, human labor, and rely on knowledge passed down through generations.
Food Crop Diversity
- Food crop diversity refers to the variety of plant species used for food.
- Diversity is crucial for:
- Resilience: Diverse crops are more resistant to pests, diseases, and climate change.
- Nutrition: Various crops offer balanced diets, reducing nutrient deficiencies.
- Cultural Significance: Many crops are tied to local traditions and identities.
- Genetic Resources: Diverse species are resources for developing new varieties.
Genetics and Food Crop Diversity
- Plant genetics determine traits like taste, appearance, and pest resistance.
- Scientists use genetics to develop new varieties with desired characteristics.
Staple Crops
- Staple crops are the foundation of many diets.
- They are high in carbohydrates and relatively easy to grow.
- Examples include rice, wheat, corn, potatoes, and cassava.
Monocultures
- Monocultures are large-scale plantings of a single crop.
- While efficient for production, they are prone to pests, diseases, and environmental factors.
Conversion of Farms into Factories
- Industrialized agriculture is characterized by large-scale operations, mechanization, and synthetic inputs.
- This transformation has increased efficiency but raised concerns about environmental and social impacts.
Environmental, Social, Economic, and Health Consequences of Modern Industrial Agriculture
- Environmental: Contributes to soil erosion, water pollution, habitat destruction, and climate change.
- Social: Leads to rural depopulation and job loss.
- Economic: Power concentrated in agribusiness corporations can harm farmers and consumers.
- Health: Excessive pesticide use poses risks to human health.
Agribusiness Consolidation
- The trend is toward fewer, larger companies controlling the food production system.
- Consolidation can affect food prices, access, and quality.
Conventional Crops vs Organic Crops
- Conventional crops may utilize synthetic fertilizers, pesticides, and genetically engineered seeds.
- Organic crops are grown using sustainable methods, avoiding synthetic inputs.
Organic Farming Techniques and Soil Health
- Organic farming prioritizes soil health through various practices:
- Crop rotation: Alternating crops to improve soil fertility and reduce pest pressure.
- Cover crops: Planting non-food crops between rows to protect soil and enhance nutrient cycling.
- Composting: Using organic materials to create nutrient-rich compost for the soil.
- Integrated pest management: Using biological, cultural, and physical methods to control pests.
- Organic farming minimizes negative environmental impacts compared to conventional methods.
Major Plant Propagation Approaches
- Seeds: Planting seeds to produce new plants.
- Cuttings: Propagating plants from a piece of stem or root.
- Grafting: Joining a plant part (scion) onto a rootstock to create a new plant.
- Tissue culture: Growing plant cells or tissues in a laboratory environment to produce new plants.
USDA Organic Label
- The USDA Organic label certifies that products meet specific standards for organic production.
- Established in 1990, the standards protect the environment, promote animal welfare, and ensure the absence of synthetic inputs.
Organic Ideal and Soil Health
- The organic ideal emphasizes the importance of healthy soil for sustainable agriculture.
- Healthy soil is vital for nutrient cycling, water retention, and microbial life.
Beyond Organic
- Sustainable agricultural practices beyond organic include:
- Regenerative agriculture
- Permaculture
- Agroecology
Consumer Role in Food System
- Consumers influence the food system through their choices.
- Informed decisions can support sustainable practices and promote food justice.
Genetically Engineered Seeds
- Genetically engineered seeds are modified in a laboratory to introduce new traits.
- This involves inserting genes from other organisms into the plant's DNA.
Biological, Legal, and Consumer Impact of Genetically Engineered Seeds
- Biologically: Genetically engineered seeds can influence plant characteristics like yield, pest resistance, and nutritional content.
- Legally: Regulation of genetically engineered crops varies by country. In the US, the FDA, USDA, and EPA are involved in the regulatory process.
- To the consumer: Debates exist about the impacts of genetically engineered crops. Benefits include improved food security and reduced pesticide use, while concerns exist about health and environmental risks.
Green Revolution and Second Green Revolution
- Green Revolution: Rapid agricultural innovation in the mid-20th century, marked by high-yielding crop varieties and modern technologies.
- Second Green Revolution: More recent focus on crops resilient to climate change and adaptable to marginal environments.
Genetic Pollution
- Genetic pollution is the unintentional transfer of genes from genetically engineered crops to other organisms.
- This can create "superweeds" resistant to herbicides, with negative ecological consequences.
Food Waste
- Food waste is a global problem, with billions of tons wasted each year.
- Consequences include environmental, economic, and social harm.
Landfill vs Compost Science
- Landfills: Contribute to greenhouse gas emissions and soil pollution.
- Composting: Decomposes organic materials, including food waste, to create nutrient-rich compost.
Food Insecurity
- Food insecurity is the lack of access to enough nutritious food.
- It is a global problem with millions of people facing food insecurity.
- Causes include poverty, conflict, natural disasters, and economic inequality.
Food Deserts
- Food deserts are areas with limited access to fresh, healthy food due to a lack of grocery stores or farmers markets.
- Efforts are underway to improve food access in such areas.
Farm Subsidies
- Farm subsidies are government payments to support agricultural production.
- Distribution can be influenced by lobbying efforts.
Consequences of Farm Subsidies
- Farm subsidies can support farmers and encourage production but also distort markets and lead to overproduction.
Tomatoland
- "Tomatoland" explores the conditions of farm workers in the United States, particularly in the tomato industry.
