Focusing on the development aspects of Fair Trade, the article reviews a range of impact evaluation methods and presents a detailed methodology for analysing Fair Trade that incorporates standard project evaluation criteria and is based on a wide range of proven methods for collecting and analysing data, principally qualitative but also quantitative.
