In the developing world, smallholders form the backbone of the agricultural sector and their importance in rural areas is almost uniform across countries. There is no unique and unambiguous definition of a smallholder. Often scale, measured in terms of the farm size is used to classify producers. For example, households with less than a threshold land size of two hectares may be characterized as smallholders. However, across countries, the distribution of farm sizes depends on a number of agro-ecological and demographic conditions and economic and technological factors.
