Subsistence agriculture refers to farming practices designed to fulfill the immediate needs of the farmer and their household, emphasizing self-sufficiency over market transactions. Historically, scholars such as F.R.H.S. Joseph Fisher underscored its essential role in national survival, whereas others, like Sir Archibald Alison, pointed out its basic nature in areas with scarce resources.
Modern studies show its continued presence in developing countries, where small-scale farmers depend on conventional techniques, intercropping, and local commerce. Although facing challenges such as climate change and urban expansion, subsistence farming continues to be a vital component of rural economies, maintaining a balance between survival and minimal surplus for trade. Its development illustrates both lasting cultural traditions and flexible adaptations to economic and environmental shifts.
