Presentation delivered by Dr Jacob van Etten at the International Agrobiodiversity Congress 2016, held in Delhi, India, 6-9 November.

In his talk, Dr van Etten brought attention to the power of citizen scientists and crowdsourcing, which has particularly helped initiatives such as 'Seeds for Needs'.

Agrobiodiversity and climate change: a new role for science

  1. 1. Agrobiodiversity and climate change: a new role for science Jacob van Etten November 2016
  2. 2. Climate change
  3. 3. Climate change Origin of agriculture
  4. 4. Drought Drought tolerance
  5. 5. Drought Heat Drought tolerance Heat tolerance
  6. 6. Climate change Real-time, one shot Climate Change: Challenge to Science Science Trial and error
  7. 7. Climate change Real-time, one shot Multiple views, values, interpretations, uncertainty Climate Change: Challenge to Science Science Trial and error Optimizing well-defined solutions
  8. 8. Climate change Real-time, one shot Multiple views, values, interpretations, uncertainty Multiple dimensions, trade- offs Climate Change: Challenge to Science Science Trial and error Optimizing well-defined solutions Ceteris paribus, isolate problem as strategy
  9. 9. Climate change Real-time, one shot Multiple views, interpretations, uncertainty Multiple dimensions, trade- offs Climate Change: Challenge to Science Science Trial and error Optimizing well-defined solutions Ceteris paribus, isolate problem as strategy Diversity
  10. 10. Aspects of a Solution Design solutions with science in supporting role – inject science into real-time workflows Work with diversity rather than averages and trends – “science of the individual”
  11. 11. Example 1
  12. 12. Working with Household Diversity
  13. 13. Household Diversity
  14. 14. Farm performance scores for large and small farm types (LF and SF), practising high and low farm intensification (HI and LI), crop diversification (HD and LD) and market orientation (HM and LM) for Lushoto, Tanzania. Abbreviations: FA is Food Availability, HFIAS is the Household Food Insecurity Access Scale, HDDS is the Household Diet Diversity Score, PPI is Progress out of Poverty Index. Trade-off analysis
  15. 15. RHoMIS Easy to use and interpret – facilitate discussion Benchmarking and comparisons possible Multiple indicators: trade-offs (adaptation vs. mitigation, etc.) Monitoring tool for NGOs, banks, state agencies, etc.
  16. 16. Example 2
  17. 17. Implementation
  18. 18. “Citizen science is scientific research conducted, in whole or in part, by amateur or nonprofessional scientists.” “(also known as crowd science, crowdsourced science, civic science or networked science)” Wikipedia Citizen Science
  19. 19. “Crowdsourcing is the process of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, rather than from traditional employees or suppliers.” Wikipedia Crowdsourcing
  20. 20. A B C Triadic Comparisons of Technologies (tricot) 12 Experimentation is done individually Each farmer receives a different combination of three varieties
  21. 21. Communication Material
  22. 22. Digital Platform
  23. 23. Accuracy of Farmer Observations 0% 10% 20% 30% 40% 50% 60% 70% Plant vigor Plant architecture Pest resistance Disease resistance Random null model None One Two Three Number of differences Tests in Honduras with 35 farmers (Steinke et al. under review)
  24. 24. Example of Results Nicaragua bean trials (Van Etten et al., Experimental Agriculture)
  25. 25. Farmer Citizen Science for Adaptation Injection of varietal diversity boosts adaptation directly through seed availability and better-adapted varieties Diversity in growing environments in a single year (planting dates, soils, rainfall) can be exploited with big data to make predictions Farmers themselves compare across sites and learn from directly observed spatial patterns
  26. 26. In Summary… Data-intensive approaches address the climate challenge from a diversity perspective Massive digital participation accelerates human learning for climate action What is the motivation of participants and those who are supposed to take up science results?
