Subsistence Farming

Subsistence FarmingWorld-wide most farmers are subsistence-growing just enough to feed their families.They find building material and fuel in the natural environment-no cash economySmall fields-intensive farming on land they often dont own.Methods and tools used are generally very low tech.Found in South & Central America, Africa, South Asia, and South East Asia

On the Greek island of Crete, a peasant plows a field with a donkey 2Crete-a peasant plows a field with a donkey

3Various kinds of maizeOxen pull a plow in PortugalShifting Agriculture-Slash & Burn, Patch or MilpaTropical areas-red soil is heavily leached.Plot of land is cleared by burning-ash replenishes soil.A type of crop rotation-tubers in warm tropics, grains in humid subtropics, fruit in cooler regions.Not nomadic-central village with parcels of land worked in successionConserves forests & soil, requires organization

4Shifting Cultivation is usually practiced in tropical areas with poor soils-soil fertility is maintained by rotating fields-note burned stumps with corn and beans interplanted. (land cleared is called Swidden)Requires less intense farming or work-but supports a lower population density than traditional farming.To outsiders Slash and Burn appears to be destructive, wasteful and disorganized-there are no neat rows of monocrops-no carefully plowed soil-Instead there are a variety of crops grown next to each other in what appears to be a jumble.
