The 2021 SPIA Webinar Series provides an opportunity for the impact assessment community of practice to jointly reflect on methods and approaches to impact assessment. Webinars will not only focus on completed work, but many of them will be presentations of work in progress. The webinars will take place on the 3rd Wednesday of each month. The topic of each webinar will be announced on this page as well as on Twitter (@cgiarspia).

Webinar #2:  Designing Rigorous Impact Assessments of CGIAR Research

The second session of our monthly webinar series took place on February 17th at 1pm CET. Participants learnt how to prepare and design rigorous and relevant impact assessments with CGIAR researchers. In this webinar, presenters shared their ideas on how to assess the impact of two CGIAR innovations that have reached the initial scaling phase.

Kelvin Shikuku presented a potential impact assessment of genetically improved tilapia. Tesfamicheal Wossen discussed the preparation for an impact assessment of Aflasafe in Africa.

Webinar #1: Lessons for Evaluating the Medium & Longer Term Impacts of CGIAR Informed Innovations That Have Gone To Scale: The Promise of Commons Experience in India

Presenters shared their experience in designing a robust impact evaluation of long-term, large-scale impacts of an institutional innovation in India to strengthen community management of natural resources. The webinar focused on lessons learned during the proposal preparation, the challenges faced, and how the study team overcame them to complete a fundable proposal.
