IFAD has to report to its Members States on the total number of rural people lifted out of poverty1. The government programmes it funds, however, are implemented in complex ways and environments that challenge mainstream evaluation practice. The challenge for IFAD and its co- implementing and co-funding partners, moreover, is not just to rigorously assess impact but also to understand the processes generating impact in order to realize its ambitious targets (IFAD, 2011). Albeit a strong emphasis on quantitative measurement, there is a need for impact evaluation that fosters learning and responsibility.

This document presents the findings from the impact evaluation of the Root & Tuber Improvement and Marketing Program (RTIMP) in Ghana. The program was executed by the Ministry of Food and Agriculture (MoFA), Government of Ghana (GoG) from 2007 until end of 2014, and co-financed by the International Fund for Agricultural Development (IFAD) for a total amount of US$ 18.83 million.
