For on-farm losses in production and harvesting there is a lot less information to report. Benin
and Guyana (cassava), Nigeria (cassava and yams) and Tajikistan and Turkey (potatoes) have
published reports of on-farm losses. Overall, the limited information for on-farm losses for
tropical root/tuber crops in the OIC Member Countries shows a range of losses that are similar
to the FAO estimates.
