WHAT WAS IT?
Period of rapid changes in agricultural practices and technologies resulting in increased productivity. All started with RICE!
Subsistence farming Commercial farmingNew strains of crops (HYV) allowed
farmers to harvest a higher yield.Use of selective breeding to create larger ears of corn.

TECHNOLOGICAL ADVANCES
Artificial fertilizer
Irrigation
Insecticides and herbicides
Mechanical machineryCombines, tractors
HybridizationCrossbreeding crops to magnify a trait, such as disease resistance and frost resistance.

Economic FactorsCost of materials (fertilizer, herbicides, fuel)
Credit unobtainable by certain groups (women, minorities)
Overwhelming debt (to farmers, to governments)
Global economyAvailability of funds (ability to take loans to purchase equipment, seeds, etc.)
OBSTACLES LDC’S HAVE TO FACE

Ecological Factors Decline in soil quality (fertility)Water pollutionFinite supply of water
Water table Seasonal droughts
Climate Erosion Desertification
Limited amount of arable landPotential loss of biodiversity
E.g. One crop takes the place of another
