Slash and Burn
•A way to clear forested land for farming
•Valuable timber is removed in
advance and either sold or used for
charcoal
•Carried out throughout the tropics,
where soils are thin, low in
nutrients,
and vulnerable to erosion
•Nutrients from burning are available
for one or two years of crops, but after
that the soil is unproductive and
people clear more land for crops
•Particularly damaging on slopes where erosion leads to rapid soil loss
