  • Food availability, access, stability and utilization are all part of the multi-dimensional nature of food security. The “availability” aspect, discussed here, refers to the availability of sufficient quantities of food of appropriate quality, supplied through domestic production or inputs. Productivity is usually considered the ultimate benchmark when comparing the performance of agricultural systems. For example, those involved in agricultural research and development want to know how much yield would be reduced if conventional agriculture were converted to organic agriculture.
