Notes & Links
Slash-and-burn: cutting down and burning vegetation in one place and planting crops there until the soil loses its nutrients, then moving on to another location.
Terracing: carving level steps into a mountain or hillside, in order to create a flat surface for planting.
Subsistence farming: a family on their own land growing just enough crops to sustain themselves, with little or no surplus to sell.
Commercial/mechanized farming: using machines and lots of land to grow large amounts of crop to sell for a profit.
Ranching:raising animals on a large but privately-owned plot of land.
Nomadic herding: moving from place to place with a herd of animals to find places for them to graze.
Plantations: growing cash crops (for profit) on a relatively large farm, mostly using resident labor (workers who live on the plantation)
Intensive farming: utilizing modern technologies and chemicals (pesticides, fertilizers, etc.) to grow as much crop as possible per square foot of land.
Genetic modification (Genetically-modified organisms, or GMOs): artificially changing the genetic code of plants and animals to generate
