The three factors, again, determine household food demand (share of household income
devoted to food purchases on the market) and household food supplies from subsistence
production. Income is the major determinant of household food demand, or in other words
- of the ability of a household to gain access to market supplies of food. Market demand for
food has an impact on the food market on the meso-economic level. This linkage between
demand and the food market is very important, as the volume of market supplies is not only
determined by production factors but also by demand factors. In fact, effective demand
constitutes a prerequisite for market oriented food production.
