Two Types of Cultivation: Vegetative Planting Vegetative Planting is the reproduction of plants using existing plants, such as cutting stems or dividing roots.

Seed Agriculture Seed Agriculture: reproduction of plants through annual planting of seeds that result from sexual fertilization. Most commonly practiced today

Carl Sauer and Agricultural Hearths Saur claimed vegetative planting happened first, and then seed agriculture. In your notes: Divide your paper into a T-chart. Write Vegetative Planting on one side, and Seed Agriculture on the other. Read pg about each and look at the maps at the top of pages 330 and 331. Take notes on both sides. Identify the hearth areas and explain how each type diffused. Add these annotations and arrows of diffusion to your map Carl Ortwin Sauer (December 24, 1889 – July 18, 1975) was an American geographer and professor at the University of California at Berkeley.

1 st Agricultural Revolution (10,000BCE to 2000BCE) Neolithic Revolution Knowledge of seeds and animal domestication Diffusion of agriculture 2 nd Agricultural Revolution (17 th to 19 th century) Coincides with the Industrial Revolution Use of machines and steam technology. Mass production begins. 3 rd Agricultural Revolution (1960’s to now) Use of science!!! Green Revolution Pesticides, herbicides Fertilizer Hybrids Agricultural Revolutions

Primary effects:  Urbanization  Social stratification (?)  Occupational specialization  Increased population densities Secondary effects:  Endemic diseases (?)  Famine Agricultural Revolutions

Origins of Agriculture Which of these areas are considered cultural hearths?

Classifying Agricultural Regions: LDC’s vs. MDC’s Subsistence Ag:  Production of food for consumption  LDC Commercial Ag:  Production of food for sale  MDC Look at the bullet points on pg. 331: What are the 5 main distinctions between subsistence and commercial?

With the person next to you, look at the map at the bottom of page 331 and the map on page 332. Also, look at the picture and the caption on page 332. Now, make some general observations about what the maps are showing you. What comparisons, contrasts, or ironies do you see? Annotate your map with your neighbor!

Agribusiness: “The industrialization of agriculture”  Modern commercial farming is very dependent on inputs of chemical fertilizer, pesticides, herbicides.  Oil is required to make fertilizer and pesticides.  It takes 10 calories of energy to create 1 calorie of food in modern agriculture.  Small farmer can’t buy needed equipment and supplies.  Fewer than 2% of U.S. population works in agriculture in the US.
