Dr. Byron Reyes has experience in assessing the impact of agricultural research in developing countries at the national and international levels. He currently works conducting impact assessment of various research initiatives in two projects: Strengthening Impact Assessment in the CGIAR System (SIAC) and the Legume Innovation Lab for Collaborative Research on Grain Legumes.  As part of his activities, he collaborates with CGIAR and National Centers, Legume Innovation Lab researchers (plant breeders, entomologists, agronomists, socio-economists) based in different U.S. universities, and with Legume Innovation Lab host country partners in Latin America and Africa. His work involves contributing to new and ongoing research which focuses on:

  • Develop, pilot, and verify innovative methods for collection and assembly of diffusion data (SIAC project);
  • Institutionalize the collection of diffusion data needed to conduct critical CGIAR impact evaluations (SIAC project);
  • Assessing the impact of agricultural research in Latin America and Africa on smallholder bean and cowpea producers (Legume Innovation Lab project);
  • Assessing the effectiveness of modern information and communication technologies (e.g., cell phone, DVDs) in disseminating information on improved agricultural technologies and practices to farmers (Legume Innovation Lab project); and
  • Evaluating the impact of bio-control agents to control cowpea pests (Legume Innovation Lab project).

Byron also has fieldwork and practical experience, which includes survey design, planning, and primary data collection; data collection thru expert elicitation using structured questionnaires; the use of molecular techniques to estimate adoption of improved varieties; and using computer assisted personal interviewing (CAPI) software to collect primary data.

Research and Outreach Interests

  • Estimate the economic impact of improved varieties in developing countries, using household level data
  • Assess the impact of agricultural research on nutrition and health in developing countries
  • Use of alternative technologies to collect household data for impact evaluation
