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.

However, measurement of productivity alone is not sufficient to evaluate the performance of an agricultural system. When natural resources are limited and production decisions are made on the basis of the economic resources available, resource efficiency is as important a criterion as productivity for evaluating a system’s performance. Thus, this paper discusses adapted technologies considers the achievements of organic agriculture in terms of both productivity and resource efficiency.

Specific attention also is given to peri-urban agriculture. In terms of the high and rapidly increasing population density in urban areas, peri-urban agriculture has the potential to minimize transportation of food products and organic waste, yet supply food to a large part of the population. 

Finally, the paper discusses how organic agriculture makes diverse food available at household, community, national and international levels. Furthermore, a summary of the organic food market is provided with most recent figures on market size and available organic food.
