Due to the losses in primary production of agriculture and fishery, subsequent losses will occur
in the processing industries and commerce that are the forward links of the production chain.
Based on a comparison of producer, wholesale and retail prices of the affected commodities12,
an order-of-magnitude estimate was made of the added value involved in these losses. These
added-value figures were combined with the volumes of primary losses of the affected
products, after discounting the volumes retained by producers for their own consumption, in
order to arrive at losses in the agro-industrial processing and marketing sub-sectors.
