3. Create a Research Tool Cheap| Robust | Easy to Use

4. Research Topics • Current Agriculture Practices • Fertilizer, manure, irrigation, pesticide, planting times, intercropping… • Existing Information System • Preferences/Use of phones, radio, cooperatives, extension agents, friends, pamphlets… • Socio-economic Characteristics • Income, education, family size, land ownership…

6. Android Fan

9. Possible Benefits

10. Possible Benefits • No need for data entry staff • Shorter hiring period for enumerators • Open source platform • Replaces existing devices in agriculture research • GPS units, navigation equipment, camera

11. Possible Benefits • Just swipe through, no flipping through papers • No switching between devices • No need to wait for data entry • Autogenerated basic reports

12. Possible Benefits • Automatic skip logic • Most data entry is automatic • Can set response types/thresholds • 3<response<7 • Response must be text, decimal, integer… • Data quality can be checked daily

13. Possible Benefits • Android operating system and open file architecture • Touch screen interface • Interchangeable keyboards

15. Our Experience

16. Research Area

17. Our Experience • Cost. Approximately 30$/ Survey (all inclusive) • Pace of Enumeration.11surveys/day • Training. 4 days rather than 2 • Device Preference. Tablets > Phones • Challenges. Multiple Apps | Data Management • Successes. Happy Enumerators | No Device Damage | On Budget

18. Pace of Enumeration

19. Future Improvements • Multiple Apps One • Data Management and Visualization • Automatic Quality Control • Package with a Manual • GPS Quality

20. Mobile Specific Challenges • Hardware/software glitch • Managing paper/digital survey changes • Charging devices daily Agriculture Specific Challenges • Recent drought • Sensitivity to yield, animal ownership questions • Fear of land-grabbing

21. Challenges for Scaling • Device charging • Batch upload of files to/from devices • Device management/tracking
