IEA managed evaluation of SIAC

The final report and management reponse from the SPIA commissioned, IEA managed evaluation of the SIAC program is out. You can also read the inception report and look through preliminary findings of the evaluation presented at ISPC 14 (ICRISAT, Hyderabad) in September 2016.

SPIA workshops and meetings on the sidelines of AAEA Boston

SPIA organized three events in tandem with AAEA 2016 (Boston). On July 29th (Fri), a day-long IAFP meeting; and, on July 30th (Sat), a mid-term workshop on the long-term/large-scale studies funded by SPIA. Following the AAEA (July 31st-August 2nd), on August 3rd (Wed) and 4th August (Thurs), SPIA, MSU and PIM organized a workshop on recent developments in measuring adoption of agricultural technologies. All event details on this page. There were also a number of sessions and panel discussions by SPIA collaborators during the AAEA: Alain de Janvry (Univ. of Berkeley), Jeff Michler (Univ. of Illinois, session 2074), and Jeff Alwang (Virginia Tech - session 2104 and session 2131) relating to impact assessments in the CGIAR.

You might also be interested in the Learning for adopting workshop jointly organized by FERDI, CERDI, and SPIA in June 2016. The website includes papers Alain de Janvry referred to in his AAEA presentation.

DIIVA project book

Edited by Tom Walker and Jeff Alwang, Crop Improvement, Adoption and Impact of Improved Varieties in Food Crops in Sub-Saharan Africa (CABI) is the result of a major follow-up effort on the Evenson and Gollin baseline. Funded by the BMGF, DIIVA greatly advanced our knowledge of varietal adoption and diffusion in SSA. You can purchase the book from the CABI site or read the PDF on the IMPACT website here.

Strengthening Impact Assessment in the CGIAR (SIAC)

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

Diffusion and Impacts of Improved Varieties in Africa (DIIVA)

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
