Form of Farming All, or nearly all, livestock and crops are

kept to use by farmer Historically, people would move from place

to place and farm Modern farming has replaced

this method Products not sold

Was predominant farming method for centuries until colonization and industrial revolution

Remote parts of the world that were not converted to commercial farms still adapt this method

Prevent erosion by terraces Alternate livestock food to prevent

overgrazing Use animal waste as fertilizer for crops Vegetation and soil retention improves soil

structure and water availability Land becomes more productive and able to

produce food

Heaving manual labor necessary Produce enough food to live on May produce more to buy other necessities

Droughts Gradual depletion of nutrients Getting essentials that can’t be grown Finding enough usable land to produce food
