摘要：This Campbell systematic review examines the effectiveness of certification schemes in improving the welfare of farmers and workers. The review summarises findings from 43 quantitative studies, and 136 qualitative studies. There is not enough evidence on the effects of CS on a range of intermediate and final socioeconomic outcomes for agricultural producers and wage workers. There are positive effects on prices. But workers? wages do not seem to benefit from the presence of CS. Income from the sale of produce is higher for certified farmers, but overall household income is not. Context matters substantially for the causal chain between interventions of certification schemes and the well being of producers and workers. Generally, the quality of the studies is mixed, with a significant number of studies that are weak on a number of methodological fronts.
