This book presents a Bangladesh case study of the farm-level postharvest system. There are two main objectives. First, to use measured estimates of food loss to test (and reject) the conventional assumptions: that postharvest farm-level food losses are large; that they can be prevented cost-effectively by technical change; and that as a consequence, there will be more food consumption by hungry people. Commonly, none of these assumptions are true and the evidence from Bangladesh, plus supporting evidence from elsewhere, is used to show why they are wrong.
