Soil management  Food Production

TalksTalks | TEDx 11 yr old Birke Baehr: What's wrong with our food system t_s_wrong_with_our_food_system.htmlhttp:// t_s_wrong_with_our_food_system.html

Subsistence agriculture Self-sufficiency farming in which the farmers focus on growing enough food to feed themselves and their families. The typical subsistence farm has a range of crops and animals needed by the family to feed and clothe themselves during the year. Planting decisions are made principally with an eye toward what the family will need during the coming year, and secondarily toward market prices.

Types of Subsidence Agriculture

Intensive Subsistence Agriculture is the cultivation of small land holdings through the expenditure of great amounts of labor. 1. practiced chiefly in overpopulated 'land hungry' areas of South Asia, especially India, Bangladesh, Sri lanka, Pakistan, Myanmar.

Commercial agriculture Large-scale production of crops for sale, intended for widespread distribution to wholesalers or retail outlets. In commercial farming crops such as wheat, maize, tea, coffee, sugarcane, cashew, rubber, banana, cotton are harvested and sold into world markets. Commercial agriculture includes livestock production and livestock grazing. Due to the expensive nature of capital formation and implementation of technological processes, the landowners of such farms are often large agricultural corporations (especially in developing countries).

Assignment: You need to compare and contrast Maasai (tribe in Kenya/Tanzania) use of cattle to the U.S. beef industry: System inputs System characteristics Socio-cultural aspects Environmental impacts Outputs Discussion to follow…

King Corn…Growing Corn What are the inputs? Rank them What are the outputs? Discuss the environmental impacts of these inputs and outputs. Corn is called a commodity. What does this mean? Does growing corn make sense economically? Why/why not? The statement was made that Iowa farmers are incredibly productive, but they can’t feed themselves off their farm anymore. What do you think about this?

Growing Cows the USA way Outline/review how cows are used as a food source in the U.S. What are the inputs/outputs? Discuss the environmental impacts of these inputs and outputs. Does this make sense economically? Why/why not?

Growing Cows the Maasai way Outline/review how cows are used as a food source for the Maasai What are the inputs/outputs? Discuss the environmental impacts of these inputs and outputs. Does this make sense economically? Why/why not? Compare and contrast Maasai cattle “agriculture” with U.S. cattle “agriculture”. What are the positive features of each? What are the negative features of each?
