This report is part of the socio-economic research in Legume Futures which aimed to assess the economic effect of including legumes in farming systems both in relation to the internal (economic) effects for the farmer and the external effects, especially on the environment. It builds on Legume Futures Report 4.5 (Impacts of legume scenarios). That report described said impacts, here we are concerned with valuing them, in order to help policy-makers arrive at a judgment on the most advantageous course of action.
The report also describes the method of social cost-benefit analysis, for the benefit of those readers who are not familiar with it. There is ample literature on this topic, but much in a concise form accessible to laymen. In a project such as Legume Futures, most participants fall into that category. Beyond mere description, the report looks critically at the method, in order to make possible users aware of its limitations as well as its usefulness.
