Abstract

The methods used in loss assessment studies must relate to the person or group suffering those losses. Greater farmer participation is needed. Self-contained loss assessment studies may be important for planning and evaluating programmes, but the emphasis should be on loss reduction projects, with loss assessment playing a much less prominent role. Sufficient methodology already exists for detailed weight loss measurement. Rapid loss assessment methods are sufficiently accurate for most purposes and should be used in field studies. For some crops or farming systems, novel loss assessment methodologies may be needed. Further work is required on calibrating rapid visual loss scales against non-weight loss criteria, elaborating losses at the traders/intermediaries level and comparing actual with perceived losses at different points in the marketing chain.
