Feeding the World

4 types of Farming Subsistence: Farming that involves only rearing enough animals and/or growing enough crops to support immediate friends and family. Cash Crop: A cash crop is an agricultural crop which is grown for sale to return a profit. Extensive: Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed. (animal farming) Intensive: Intensive farming or intensive agriculture is a kind of agriculture where a lot of capital and labour are used to increase the yield that can be obtained per area. (wheat, corn production)

World Food Production and Population

Green Revolution https://www.youtube.com/watch?v=c6Ids_RK6XM

Green Revolution - Pros The Green revolution is a controversial topic. It has increased the ability to grow food drastically, particularly in the developed world. Crops are easier to grow as they are genetically chosen for their environment. They made farming more profitable and less labour intensive. Created a food industry using the technology of the industrial revolution. (Machines and factories replacing human labour)

Green Revolution Cons Seeds are expensive. Genetically manufactured for Western environments. Crops that had two growing seasons did not give the soil enough chance to recover nutrients. Soil degradation. Chemical Fertilizers became mandatory for soil, extra costs for poor farmers. Too expensive for the developing world. Needed large amounts of water. Dams flooded villages

Green Revolution Cons Created water scarcity issues Water pollution increased due to fertilizer use. Created industrial farming. Could only be profitable if grown in large fields with massive amounts of fertilizers. Tractors replaced workers. Increased unemployment. Not a good solution for poorer countries who cannot afford machinery, fertilizers or seed technology.

Current Food Shortage

World Food Shortage Our Population is expected to grow to 9 billion. This growth is mostly happening in the less developed and least developed countries of the world. These regions produce the least amounts of food. We need to produce about 50% more food by 2050 to feed everyone. This would make up for the problems of food shortages today and in the future.

World Food Shortage Climate Change is creating world wide drought. Water resources are dwindling The graph below is all based on population leveling off in least developed countries.

Waste Approximately 40 percent of food in the U.S. goes to waste. -Food and Agriculture Organization(FAO) Roughly one third of the food produced in the world for human consumption every year — approximately 1.3 billion tons — gets lost or wasted. (FAO) Every year, consumers in rich countries waste almost as much food (222 million tons) as the entire net food production of sub-Saharan Africa (230 million tons). (FAO) Each year an average 7% of U.S.-planted acreage was not harvested between 1994-96. USDA Economic Research Service
