There’s an app for that? The impact of Community Knowledge Workers in Uganda

  1. 1. There’s an app for that? The impact of Community Knowledge Workers in Uganda Bjorn Van Campenhout IFPRI - Kampala ICT4Ag International Conference - 4-8 November 2013 - Kigali, Rwanda
  2. 2. Context • IFPRI Kampala was asked to do an impact assessment of the CKW project in Uganda using best method given time and budget • CKW = Community Knowledge Worker – Locally recruited – Smartphones (GPRS/EDGE) – Comprehensive information
  3. 3. Difference-in-Differences study: Methodology • One could calculate the difference between farmer’s outcomes who are served by CKWs, and farmer’s outcomes that are not, but the estimate will include a selection effect – CKWs may be deployed in agriculturally favorable areas • One could calculate the difference between a farmer’s outcomes before the CKW intervention and the SAME farmer’s outcomes after the intervention, but the estimate will include all things that affect the outcome – Bumper harvest, drought, sick family member, etc. • One could compare the difference between the outcomes of farmers that were served by CKWs and the outcomes of farmers that were not served by CKWs, with the difference between the outcomes of these two groups before CKWs were introduced. – In other words, one controls for the fact that farmers that receive CKW services might be different to begin with.
  4. 4. Difference-in-Differences study: Methodology
  5. 5. Difference-in-Differences study: Data • Surveyed farmers in three CKW districts after CKW – Kapchorwa, Gulu and Oyam and two control districts Sironko and Lira for 2011/12. • Used 2 surveys before CKW: • UNHS 2005/06 • WFP2009/10 ! Subset of treated households form a panel 2009/10 – 2011/12 !
  6. 6. Results: Crop portfolio
  7. 7. Results: Maize Productivity
  8. 8. Results: share of maize sold
  9. 9. Results: price of maize sold
  10. 10. Treatment intensity
  11. 11. Conclusions • CKW makes a difference: – Change in crop mix – Higher price for maize – Lower share of maize sold • But: no effect on productivity… why? • Information is public good
