GREEN REVOLUTION = LDC
WHAT WAS IT? Period of rapid changes in agricultural practices and technologies resulting in increased productivity. All started with RICE! Subsistence farming Commercial farming New 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 machinery Combines, tractors Hybridization Crossbreeding crops to magnify a trait, such as disease resistance and frost resistance.
EXAMPLES OF WHERE IT WAS SUCCESSFUL Asia India Philippines China Vietnam Latin America Mexico Northern Africa The Green Revolution occurred only in LDCs, not in the United States or Europe
Social Middle class farmers Education Availability of credit, money, banks Transportation system (infrastructure) Political Market economy Receptive political environment Political Stability Cultural Acceptance of new crops and practices FACTORS NECESSARY TO MAKE IT SUCCESSFUL
Economic Factors Cost of materials (fertilizer, herbicides, fuel) Credit unobtainable by certain groups (women, minorities) Overwhelming debt (to farmers, to governments) Global economy Availability 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 pollution Finite supply of water Water table Seasonal droughts Climate Erosion Desertification Limited amount of arable land Potential loss of biodiversity E.g. One crop takes the place of another
