Benefits Of Subsistence Farming. Subsistence farming merely means only being able to grow and produce enough food to sustain yourself. There really is no benefit from it other than you secure enough food for your survival. It would be very labor intensive and time consuming and you would probably have little time for other activities.
Intensive Agriculture. Intensive agriculture is the primary subsistence pattern of large-scale, populous societies. It results in much more food being produced per acre compared to other subsistence patterns.his required a radical change in the concept of ownership. In most small-scale societies with less intensive subsistence patterns, economically important properties, such as land and water wells, usually are not owned in the sense that we think of ownership today.
