Currently, poverty in developing countries is so great that many cannot afford the food they need. As climate change and a growing population population place greater strains on the world food supply, food prices will only increase. By taking measures to alleviate poverty and decrease nonessential uses of crops, food can be made affordable on a global level.
Harmful practices like over-farming and premature harvesting can waste large amounts of food. Production waste can be decreased through improved communication between smallholder farmers, the harvesting of entire crops, and the donation or composting of unsold crops.
In developed countries, waste of edible foods can be decreased by having consumers pay for their waste through a “trash scale” system, replacing barcodes with Radio Frequency Identification (RFID) tags to track food, and increasing donations to food banks
Consumers can support local farms, buy less food, eat smaller portions, and implement technology to track their waste.
Food supply loss due to biofuel production can be minimized by gradually phasing out government funded food-crop subsidies for biofuels and increasing funding for research and development of second and third generation biofuels (eg. agricultural waste, algae, switchgrass) instead of first generation biofuels (eg. corn starch, sugar cane). In addition, by growing biofuel crops on poor food crop land, deforestation can be limited and more cultivable land can go to meeting food demands.
Crop waste fed to livestock can be minimized by moving towards an unsubsidized livestock industry by reducing subsidies to the livestock industry by 10% annually for 10 years. Another important measure is the education of the population on the environmental impact livestock. These methods should reduce animal product consumption by at least 50%.
