2. Agricultural Origins and Regions
Origins of agriculture
Hunters and gatherers
Invention of agriculture
Location of agricultural hearths
Vegetative planting, seed agriculture
Classifying agricultural regions
Subsistence vs. commercial agriculture
Subsistence is grown for yourself and family; commercial is solely grown for business
Mapping agricultural regions

3. Vegetative Planting Hearths
There were several main hearths, or centers of origin, for vegetative crops (roots and tubers, etc.), from which the crops diffused to other areas.

4. Seed Agriculture Hearths
Seed agriculture also originated in several hearths and diffused from those elsewhere.

5. 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.

6. Tractors, per Population
Tractors per 1,000 people. Use of machinery is extensive in most MDC agriculture,
but it is much less common in LDCs.

7. World Agriculture Regions
Locations of the major types of subsistence and commercial agriculture.

8. 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.

9. 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.

10. World Milk Production
Milk production reflects culture, environment, sometimes wealth. It is usually high in MDCs,
especially production per capita, and varies considerably in LDCs. However, not all cultures
drink milk or can digest it, so it’s not necessarily a sign of wealth. Traditional Yorubas never
drank milk, and yet they were not poor. They ate curds, instead (a product of milk).

11. 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.

12. Grain Importers and Exporters
Most countries are net importers of grain. The U.S. is the largest net exporter.

13. Meat Production on Ranches
Cattle, sheep, and goats are the main meat animals raised on ranches.

14. 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
(the fringes of the major deserts of the world).

15. The Sahel
The Sahel, which is south of the Sahara, frequently faces drought and food shortages,
as does the Horn of Africa. This boundary is an area of cultural, religious and physical mix.
