The POSTCOSECHA program was developed by SDC in the 1980ies in Honduras and scaled up to Central Amercia. The program ended in 2003, but its post-harvest strategy keeps flourishing today. The main technology element of the POSTCOSECHA program are locally produced metal silos to protect and store grain. The program has sustainably anchored technology production and technology dissemination in existing institutions and market mechanisms.

The massive dissemination of silo technology has been a success. Today, one fifth of all maize and bean producers in Central America own a hermetically sealed metal silo previously unknown in the region. Fumigation allows the silo owners to get rid of damaging insects contained in the grain to be stored. For small-scale farmers the silos represent a secure, long-term and practical solution to a problem that negatively affected the security of their livelihoods.

The strategy of the POSTCOSECHA program consists of 4 elements:

Local tinsmiths produce metal silos. Farmers store their grain in the silos, where it is protected. Fumigation against insect infestation effectively reduces losses.

Public and NGO training & development institutions propagate the technology and carry out trainings for farmers and tinsmiths.

Business model
Public funds are used to finance the strategy support measures. Private funds (family savings or funds from donor institutions) are used by tinsmiths to start or upgrade their businesses, and by farmers to purchase the silos.

Management mechanism
Independent project management units (PMUs) manage POSTCOSECHA projects. The main activities of those PMUs are planning, coordination, quality control, and controlling.

The POSTCOSECHA strategy has proved to be highly beneficial:
Farmers in Central America typically are able to pay off their initial investment of 30 to 100 USD within one or two harvest cycles, while benefits last for 15 to 20 years.

An outstanding success​

670’000 metal silos in 4 Central American Countries
336'000 tons of grain saved annually (mainly maize)
100'000'000 US $ additional income for farmers
12'000'000 US $ profit by 900 tinsmiths producing metal silos
And: POSTCOSECHA keeps flourishing after end of programme
