"This paper examines the impact of IFAD-supported projects so as to learn lessons for future projects. It analyses the different methods used by IFAD to measure a project's impact, finds that IFAD is improving the well-being of rural people, and recommends that impact assessments be built into future projects from their inception."--

In recent years, the International Fund for Agricultural Development (IFAD) has increasingly strengthened its focus on achieving and measuring results. In 2011-2012, resources were invested in the IFAD9 Impact Assessment Initiative (IFAD9 IAI) in order to: (i) explore methodologies to assess impact; (ii) measure - to the degree possible - the results and impacts of IFAD-financed activities; and (iii) summarize lessons learned and advise on rigorous and cost-effective approaches to attributing impact to IFAD interventions. The initiative reflects a recognition of IFAD's responsibility to generate evidence of the success of IFAD-supported projects so as to learn lessons for the benefit of future projects. This paper describes the IFAD9 IAI and the range of methods that have been identified to broaden the evidence base for the estimation of IFAD impacts, and presents the results from the aggregation and projection methodology used to compute the Fund's aggregate impact on key outcomes, while also highlighting what has been learned. The results show that there are many areas in which IFAD-supported project beneficiaries have had, on average, better outcomes in percentage terms as compared to comparison farmers who were not project beneficiaries. Specifically, IFAD-supported projects are effectively poverty-reducing: when choosing durable asset indexes as the preferred poverty proxies on the grounds that they better approximate long-run wealth, findings point to statistically significant gains. Overall, the analyses strongly imply that IFAD is effectively improving the well-being of rural people in terms of asset accumulation, and higher revenue and income. The IFAD9 IAI represents a pioneering research effort, which has tried to overcome the clear challenges of designing data collection and conducting ex post impact assessments in a context where data were scarce, with a view to measuring progress towards a global accountability goal over a very short period of time. Therefore, an important recommendation is that future impact assessments should be selected and designed ex ante, and structured to facilitate and maximize learning, rather than used solely as an instrument to prove accountability.

This paper describes the Participatory Impact Assessment and Learning Approach (PIALA) which was developed and piloted by IFAD. The approach aims to produce rigorous qualitative and quantitative evidence that can be used not only to identify and assess the impacts of development projects, but also to promote learning and improved understanding of the associated processes and pathways of socio-economic change. Illustrated with cases from Viet Nam and Ghana, the paper assesses the value of the approach for collaborative learning and reporting for IFAD's country programming and global policy engagement, as well as for the wider development community.

Assessing impacts of public investments has long captured the interest and attention of the development community. This paper presents the evolution of different methods and approaches used for ex ante appraisal, monitoring, project evaluation, and impact assessment over the last five decades. Among these tools, impact assessment (IA) conducted retrospectively comes closest to providing the proof of development effectiveness. It is defined as the systematic analysis of the significant or lasting changes in people's lives brought about by a given action or series of actions in relation to a counterfactual. There are three basic types of retrospective IAs: macro-level IAs that focus on the contribution of developmental efforts to an impact goal aggregated at a sector or a system level; micro-level impact evaluations (IEs) concerned with estimating the average effect of an intervention on outcomes at the beneficiary level; and micro-level ex post impact analysis concerned with total effects of a development effort after the outputs are scaled-up. Ex post IAs have evolved and expanded over the decades in both breadth and depth of analysis in response to evolving development themes and methodological advancements. The increased emphasis on learning from evaluations has also seen responses from both quantitative and qualitative camps of the evaluation community. The paper argues that generation of robust knowledge that feeds into making developmental policies and investment decisions requires a hierarchical and cumulative approach to "improving the proof" through rigorous and a variety of impact assessment methods applied incrementally at the project, program and system level. Subjecting as many development interventions as resources allow to rigorous impact assessment based on a common framework can help build a critical body of evidence on impacts of development interventions, which can then be subjected to meta-analyses to help assimilate results across different studies and build a knowledge base on what works and what does not.
