2 ways to increase global food productionIncrease crop yields or increase
acres of cropland. Problems w/ increasing production:
Lack of water for irrigation,reduced genetic diversity, decreasing productivity, degrading environmental effects

This “doubly green revolution” will benefit the poor more than past revolutions because it will allow people to grow or purchase enough food for their survival/good health

Organic FarmingOrganic Farming
Currently used on less than 1% of world’s farmland
Requirements to be considered organic:Produced without synthetic
pesticides,etcCannot include genetically
engineered foodsCannot be irradiated or be grown in
soil fertilized by sewage sludge.

Results of Organic Farming
Results of Organic Farming
Produces high yields with limited emissions
Uses 50% less energy than conventional farming
Improves soil fertilityProvides more habitat for wild
plant/animal speciesGenerally more profitable for the
farmer

Increase:High yield polyculture, organic fertilizers, biological pest control, integrated pest management, irrigation efficiency, perennial crops, crop rotation, soil conservation and subsidies for
more sustainable farming techniques.
