A recognized (and well-acknowledged) drawback of RCTs is general equilibrium concerns. What happens to (potential) impacts when interventions studied in field experiments scale-up, as in agricultural technology adoption? Even when RCTs...
Key results on adoption of 20 food crops across 30 countries in Sub-Saharan Africa, data for which was collected as a part of the Diffusion and Impact of Improved Varieties in Africa (DIIVA) project, are presented in this Brief. Direct link to Impact Brief No 41, and DIIVA project information page.
Presentations from the IAFP Meeting, Minneapolis are now available. IAFPs presented on recently completed studies, new IA approaches and studies underway, constraints to effective IA of Center and CRP research, as well as challenges in IA, particularly in the context of CRPs. More information on the Events page.

SIAC is a major new initiative from SPIA funded by DFID, the Gates Foundation, and ISPC with a budget of US$ 12 million over 2013-2016 for a range of activities. The key objectives of SIAC are:
- Methods: Develop, pilot and verify innovate methods for collection and assembly of diffusion data
- Outcomes: Institutionalize the collection of diffusion data needed to conduct critical CGIAR impact evaluations
- Impacts: Assess the full range of impacts from CGIAR research
- Building a community of practice: Support the development of communities of practice for ex post impact assessment within the CGIAR and between the CGIAR and the development community more broadly
There are three major components to this outcomes and impact study which is supported by a 3-year, US$3 million grant from the Gates Foundation.
- To describe investments in and uptake of crop genetic improvement in priority country-by-commodity combinations in Sub-Saharan Africa (SSA)
- To verify and gain a deeper understanding about the adoption and diffusion of new varieties in a nationally representative setting of selected priority countries and food crops in SSA
- To gain a more comprehensive understanding of the impact of crop improvement on poverty, nutrition and food security
