Subsistence Farming is a form of agriculture that is primarily focused on meeting the immediate needs of a farmer's family rather than producing for sale in the market. It employs traditional techniques, lower levels of technology, and often relies heavily on household labor. This type of farming can be classified into two main categories: intensive subsistence farming, characterized by small plots of land cultivated intensively to produce various crops, and primitive subsistence farming, which includes practices such as shifting cultivation and nomadic herding. Intensive subsistence farming predominates in densely populated regions, particularly in monsoon areas of Asia, while primitive subsistence farming is found in regions where the soil and climate support such practices. This section highlights the critical role of subsistence farming in ensuring food security for families, especially in less developed regions.
