Intensive and Extensive Agriculture
In this type of farming system, crops are grown mainly for local consumption. If there is a surplus, then it is sold in the market. This type of farming is largely found in densely populated regions of monsoon Asia.
Basically, there are two types of intensive subsistence agriculture. One is dominated by wet paddy and the other is dominated by crops such as sorghum, soybeans, sugarcane, maize, and vegetables.
Areas of Intensive Subsistence Farming are Tonking Delta (Vietnam), lower Menem (Thailand); lower Irrawaddy (Myanmar); and the Ganga-Brahmaputra Delta, Eastern Coastal Plains (India).
