- Combination of science, art and business directed at the cultivation
of crops
and the raising of livestock for sustenance and profit
- Hunting and gathering
- Activities whereby people feed themselves by killing wild animals and
gathering fruits, roots, nuts, and other edible plants
- Subsistence agriculture
- A system in which agriculturalists consume most of that they produce
- Domestication of animals and plants could enable them to settle in
one place
over time
- Diminishing nowadays
- They are all a part of social system
- Three dominant forms
- Shifting cultivation
- Land rotation
- Rotating the fields within which cultivation occurs

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

- Crop rotation
- Mainly in tropical forest
- To maintain soil fertility
- Crops planted are changed to balance the types of
nutrients
withdrawn from and delivered to the soil
- Slash-and-burn
- Typical method to prepare a new site
- Existing plants are cropped close to ground, left to dry
for a
period, then burned
- Burning process adds valuable nutrients to the soil (e.g.
Potash) as fertilizer
- Ecologically destructive when large number of farmers
participate and in endangered species areas (e.g.
rainforest)
- Good response to fragile landscape; passive effectively
restoring plant nutrition to the soil
- Helps protect soil from leaching and erosion
- No manufactured fertilizer, pesticides, herbicides or
heavy
equipments
