Chapter 10 “Agriculture” Global Food Crisis – 2009! Most Canadians take food for granted. Even the poorest fifth of households in the United States spend only 16 percent of their budget on food. In many other countries, it is less of a given. Nigerian families spend 73 percent of their budgets to eat, Vietnamese 65 percent, Indonesians half. Last year, the food import bill of developing countries rose by 25 percent as food prices rose to levels not seen in a generation. Corn doubled in price over the last two years. Wheat reached its highest price in 28 years. The increases are already sparking unrest from Haiti to Egypt. Many countries have imposed price controls on food or taxes on agricultural exports. The World Bank, the UN, the International Monetary Fund and the Food and Agricultural Organization (FAO) warned that rising food prices may cause social unrest, malnutrition and even starvation. Not only are food prices rising but food stocks, especially cereal are at an all time low. Causes for high food prices: •Increase in energy costs – increase shipping and production costs •The rise of the middle class in India and China – want more meat (protein) in their diet thus more grain to feed not people but cows, goats, pigs etc. •Climate changes – Global Warming – droughts, floods and storms have decreased crop yields around the world but in particular in Great Britain and the Ukraine •More and more land and crops are being converted to corn and the production of Ethanol (biofuel) •More demand for corn caused an increase in corn and feed prices •Many countries place tariffs on import ethanol – thus increasing domestic production •Rich countries with money, research and technology can adapt, but not poor countries Solutions: •Stop ethanol production – burning ethanol really does not help the environment – so stop its production •MDC countries must help the LDC with financial aid, food aid and educational aid •The MDC must re-think their energy policies •FAO plans to give out vouchers to farmers in poor countries to purchase seeds and fertilizer and to help them adapt to changing climate conditions – the key is to help countries grow food locally and not have to rely on imports •The European Union is eliminating tariffs on cereal imports – to keep prices down •Some countries pay their farmers not to grow certain crops or use certain land (to keep prices and supply in check). These practices have to be removed. The previous four slides were taken from the following articles: 1. The Food Crisis – The New York Times, April, 2008 2. World food stocks dwindling rapidly, UN warns, by Elisabeth Rosenthal, International Herald Tribune, December 17, 2007 Agriculture: Deliberate modification of Earth’s surface through cultivation of plants and rearing animals for sustenance and/or economic gains.

Seed Agriculture Hearths Seed agriculture also originated in several hearths and diffused from those elsewhere. Three main types of Agriculture: Extensive – … Intensive – … Subsistence – …. Extensive and Intensive is considered COMMERCIAL FARMING and done by the MDCs. Subsistence is considered SUBSISTENCE FARMING and done by the LDCs SUBSISTENCE FARMING •… •… •… •… •… •… •… Types: SHIFTING CULTIVATION PASTORAL NOMADISM INSTENSIVE SUBSISTENCE We will expand each one of these in class COMMERCIAL FARMING •… •… •… •… •… •… •… Types: MIXED CROP/LIVESTOCK DAIRY FARMING GRAIN FARMING LIVESTOCK FARMING MEDITERRANEAN FARMING TRUCK FARMING PLANTATION FARMING We will expand each one of these in class Slash and Burn Subsistence Farming Commercial Farming Pastoral Nomadism Terraced rice farming Grain Farming - Wheat Green Revolution GMO’s Two very important people have to be studied when dealing with Agriculture: Esther Boserup –discussed in the chapter on Population - mention her theory now. Von Thunen – view the separate slide show that goes with this chapter The following slides contain a series of maps for us to look at and analyze and come up with some generalizations about Agriculture. Labor Force in Agriculture A large proportion of workers in most LDCs are in agriculture, while only a small percentage of workers in MDCs are engaged in agriculture. World Agriculture Regions Locations of the major types of subsistence and commercial agriculture. World Climate Regions Simplified map of the main world climate regions World Rice Production Asian farmers grow over 90% of the world’s rice. India and China alone account for over half of world rice production. World Corn (Maize) Production The U.S. and China are the leading producers of corn (maize) in the world. Much of the corn in both countries is used for animal feed. World Milk Production Milk production reflects wealth, culture, and environment. It is usually high in MDCs, especially production per capita, and varies considerably in LDCs. World Wheat Production China is the world’s leading wheat producer, but the U.S. and Canada account for about half of world wheat exports. Meat Production on Ranches Cattle, sheep, and goats are the main meat animals raised on ranches. Desertification Hazard The most severe desertification hazards are in northern Africa, central Australia, and the southwestern parts of Africa, Asia, North America, and South America. Grain Importers and Exporters Most countries are net importers of grain. The U.S. is the largest net exporter. Drug Crops Of course not all crops are grown for food. There is Cotton and Tobacco, Natural Rubber, Tea and Coffee. There is also Coca (Cocaine) - Colombia, Peru and Bolivia, Marijuana - Mexico, Opium – Afghanistan, Myanmar, Laos and Thailand, and Hashish - Mexico as well.
