Study Notes
Agriculture: Cultivating Life
- Agriculture is the practice of cultivating plants and raising animals to produce food, fiber, medicine, and other essential products needed for human life.
Goals of Agriculture
- Provide food security and a stable food supply for a growing population.
- Promote economic growth, particularly in rural areas.
- Contribute to environmental sustainability and conservation.
- Enhance human health and nutrition through diverse agricultural products.
Agricultural Practices: Traditional and Modern Approaches
- Traditional practices rely on time-tested methods passed down through generations, often using minimal technology.
- Modern practices utilize scientific advancements and technology to boost productivity and efficiency.
Traditional Agricultural Practices
- Rice terracing: carving terraces into mountain slopes to control water flow for irrigation. This is sustainable and preserves important cultural heritage, especially in areas like the Banaue Rice Terraces in the Philippines.
- Slash-and-burn (Kaingin): clearing land by cutting and burning vegetation for farming. This is a controversial practice due to its negative environmental impact, but it has been used traditionally for subsistence farming in many regions.
- Multi-cropping: planting different crops in the same location simultaneously. This approach increases biodiversity, maximizes land use, reduces crop failure risks, and supports local economies.
- Crop rotation: growing different types of crops in sequence across seasons. This helps to replenish soil nutrients, control pests, and maintain soil health.
Modern Agricultural Practices
- GMO seed technology: using hybrid seeds to increase yields and pest resistance. This technology, while controversial, helps ensure food security and improve productivity for common crops like rice, corn, and vegetables.
- Aquaponics and hydroponics: growing crops without soil in nutrient-rich water, often in urban areas or regions with poor soil quality. This method promotes food security and provides a solution for challenging agricultural environments.
Livestock and Aquaculture Practices
- Pond culture: raising fish in enclosed ponds where water quality and feed can be monitored and controlled.
- Cage culture: cultivating fish in cages or enclosures submerged in natural water bodies. This approach provides access to natural water flow while keeping the fish contained.
- Integrated Multi-Trophic Aquaculture (IMTA): farming multiple species together in a complementary way, creating a balanced ecosystem within the aquaculture system.
- Seaweed and algae farming: cultivating marine plants for food, cosmetics, and biofuels. This occurs in open water or in controlled tanks.
- Shellfish farming: cultivating species like oysters, clams, and mussels in natural bodies of water using anchored racks, bags, or cages.
Impacts of Agricultural and Aquacultural Practices: Balancing Productivity and the Environment
- Soil degradation: erosion (loss of topsoil), nutrient depletion, and salinization.
- Water quality: nutrient runoff (eutrophication), pesticide and herbicide contamination.
- Biodiversity loss: habitat destruction, overuse of chemicals, and introduction of invasive species.
Biomes: Large Ecological Areas
- Biomes are vast ecological areas characterized by distinct climate, soil, plants, and animal life.
