Agriculture & Land Management - Complete Interactive Lesson
Part 1: Core Concepts
🌾 Agriculture & Land Use
Part 1 of 7 — Farming Practices and Environmental Impacts
Agricultural Revolution Timeline
| Revolution | Period | Key Changes |
|---|---|---|
| First Agricultural Revolution | ~10,000 years ago | Shift from hunter-gatherer to farming; domestication of plants and animals |
| Second (Industrial) | 1700s-1800s | Mechanization; seed drill, crop rotation, selective breeding |
| Green Revolution | 1960s-1970s | High-yield crop varieties, synthetic fertilizers, pesticides, irrigation |
Farming Methods
| Method | Description | Environmental Impact |
|---|---|---|
| Monoculture | Growing one crop over large area | Depletes soil nutrients; vulnerable to pests; requires more pesticides |
| Polyculture | Growing multiple crops together | Better pest control; maintains soil health; more resilient |
| No-till farming | Seeds planted without plowing | Reduces soil erosion; preserves soil structure |
| Contour plowing | Plowing along hillside contours | Reduces water runoff and soil erosion |
| Terracing | Cutting flat steps into hillsides | Prevents erosion on steep slopes |
| Crop rotation | Alternating crops seasonally | Restores soil nutrients; breaks pest cycles |
| Cover crops | Planting non-harvest crops between seasons | Prevents erosion; adds nitrogen (legumes) |
| Integrated Pest Management (IPM) | Combines biological, cultural, chemical controls | Reduces pesticide use; targets pests precisely |
Concept Check 🎯
Environmental Impacts of Agriculture
| Impact | Cause | Consequence |
|---|---|---|
| Soil erosion | Plowing, deforestation, overgrazing | Loss of topsoil; sedimentation in waterways |
| Salinization | Irrigation in arid areas | Salt buildup makes soil infertile |
| Waterlogging | Over-irrigation | Roots suffocate; soil becomes compacted |
| Desertification | Overgrazing, deforestation, poor farming | Fertile land becomes desert |
| Eutrophication | Fertilizer runoff (N and P) | Algal blooms; dead zones in water |
| Pesticide resistance | Overuse of pesticides | Pests evolve resistance; requires more chemicals |
| Bioaccumulation | Persistent pesticides (DDT) | Toxins concentrate up the food chain |
Genetically Modified Organisms (GMOs)
| Pros | Cons |
|---|---|
| Higher yields | Potential biodiversity loss |
| Pest resistance (Bt crops) | Gene flow to wild relatives |
| Drought tolerance | Corporate seed dependency |
| Reduced pesticide use for some crops | Consumer health concerns (debated) |
| Nutrient enhancement (Golden Rice) | May encourage monoculture |
Applied Recall ✍️
-
Growing a single crop over a large area is called _______, which depletes soil nutrients and increases pest vulnerability.
-
Salt buildup in soil from irrigation in arid climates is called _______.
-
The practice that combines biological, cultural, and limited chemical controls to manage pests is called _______ Pest Management.
Match the Practice 🔍
AP Exam Strategy: Agriculture
- Know specific soil conservation practices and what problem each one addresses
- Green Revolution trade-offs are commonly tested: increased yield but increased environmental impact
- Understand IPM as the preferred approach over heavy pesticide use
- Salinization and waterlogging are caused by IRRIGATION (a common FRQ topic)
- Bioaccumulation vs biomagnification: bioaccumulation = within one organism; biomagnification = increasing concentration up food chain
