Machinery can only work productively if it is kept in good order, and this means a regular supply of replacement parts. Unfortunately, in many countries, farm power has been introduced without the necessary infrastructure to support it. Consequently, the working life of machinery has been shortened to the point where its use is totally uneconomical. All too often, machinery has not enjoyed parts availability sufficient for routine maintenance, let alone to repair breakdowns. The logical solution to the problem is to ensure an organization exists with the funds, facilities, equipment and expertise to stock parts needed to keep machinery working. FAO is actively involved in assisting with the establishment of businesses dealing with replacement parts.
