8 extensive agriculture 2. extensive agriculture : large areas of land & less labor input - yield per unit area is low & populations are low 3. Systems of production: - subsistence (for survival) - commercial (for sale)

9 C. Types of Subsistence Agriculture 1. Shifting cultivation 1. Shifting cultivation (swidden agriculture): a type of subsistence farming found in tropical rain forest areas  also called slash-and-burn or milpa  cutting, burning (fertilizes & clears pests), then planting  5% of world (Amazon, Congo, Indonesia)
