Household metal silos

The household metal silo is a key post-harvest technology in the fight against hunger and for food security. It is a simple structure that allows grains to be kept for long periods and prevents attack from pests such as rodents, insects and birds. If the grains have been properly dried (<14 percent moisture in the case of cereals and <10 percent in the case of pulses and oilseeds) and the household metal silo is kept under cover, there are no problems of moisture condensation in its interior. Household metal silos generally hold between 100 and 3 000 kilos. A household metal silo  with a capacity of 1 000 kilos can conserve the grain needed to feed a family of five for one year. A small or medium farmer with more than one silo can store surpluses for off-season sale when prices are more attractive, thus increasing household income.  Other institutions, such as Swiss Cooperation in Central America in the 1980s, have had positive experiences with household metal silos and FAO has successfully disseminated this technology in the last ten years in 16 countries in three continents
