Transcript

  1. David Arango and Frederick Atieno Researchers CCAFS-CIAT and Bioversity Training Workshop Dar es Salaam, Tanzania 21th- 24th July Applications of the Climate Analogues approach for site specific adaptation measures in agriculture
  2. Climate Analogues Dar es Salaam, Tanzania David Arango and Frederick Atieno Researchers CCAFS-CIAT and Bioversity
  3. 1. What is the Climate Analogues approach? 2. Applications of the Climate Analogues approach
  4. 1. What is the Climate Analogues approach? 2. Applications of the Climate Analogues approach
  5. What is the Climate Analogues approach? The Climate Analogues approach identifies areas where the climate today is similar (analogous) to the future projected climate of another area.
  6. •Jointly developed by the Walker Institude (University of Reading, UK) and the program “Decision and Policy Analysis” (DAPA) at CIAT •Financed by CCAFS theme 1: Adaptation to progressive climate change •In colaboration with other contributing people and institutions What is the Climate Analogues approach?
  7. Definition of a Climate Analogue • The term climate analogues describes two sites that share similar climatic conditions. •The two sites may be separated geographically and/or temporally (i.e. similar climatic conditions experienced at different periods of time) as climatic conditions change and migrate.
  8. •Compares locations based on similarity in precipitation and temperature but it is also flexible to incorporate other input variables (e.g. soils, infrastructure, social and economic conditions). Concept of a Climate Analogues
  9. Possible analogues BACKWARD •Where can I find the future climate of my site today? MY SITE (future) OTHER SITE (s) (current)
  10. Possible analogues FORWARD •Where can I find the present climate of my site in the future? MY SITE (current) OTHER SITE (s) (future)
  11. Possible analogues NONE •Where can I find the present climate of my site in the world currently? MY SITE (current) OTHER SITE (s) (current)
  12. The climate data use by analogues  Present climate: WorldClim = interpolated data set of climatic observations , between the years 1950-2000  Future climate: - downsaclaed projected conditions for the decade 2030 (i.e. 2020-2049) - scenarios: A1B, A2,B1 - there are 24 GCMs and also an “Ensemble” option which is the mean of all GCMS -30.1 30.5 Mean annual temperature (ºC) 0 12084 Annual precipitation (mm)
  13. Emissions scenarios •The emissions scenarios are the results of models used to simulate the future production of greenhouse gases (GHGs) with global development following different socio-economic focus points. (i.e. introduction of renewable energy vs. continued dependence on fossil fuels). •The different scenarios forecast different GHGs levels in the atmosphere which then translate into variations in future predicted climatic conditions.
  14. How do you calculate climatic similiarity? Climatic similarity is calculated as a vector in n dimensional space. n = number of input parameters Climatic Distance CCAFS Similarity Index
  15. How do you calculate climatic similarity? m: number of time periods (in months, days) v: number of variables V: variable (temperature, precipitation) W: weight f: scenario at reference site (future climate) p: scenario in search range (present climate) k: variable specific similarity index constant (used to merge variables on different scales) Climatic Distance CCAFS Similarity Index
  16. Input Parameters Growing season of interest - Entire year - Growing season of a specific crop - Rainy season Seasonal variability- The rotation option
  17. Input Parameters Climate models •You may choose between any of the 24 GCMs •Or the average of all 24 GCMs = Ensemble  Reduces uncertainty from using a single model
  18. Input Parameters Climatic variables Combinations of bioclimatic variables also available Temperature only Temperature and precipitation Precipitation only When using multiple variables it is possible to vary the weight of each depending on the importance that you want it to have in the overall analysis
  19. •Climate Analogues is available for use through: •Functional in Firefox, Google Chrome and IE
  20. http://analogues.ciat.cgiar.org/climate/
  21. After an analysis… •Visually investigate the results •Rerun with different variables •Download results and information •Download the code to use in R •…Validate results with other data sources
  22. Lets look at an example from the online tool
  23. 1. What is the Climate Analogues approach? 2. Applications of the Climate Analogues approach
  24. What are the application of Climate Analogues? -Explain differences in crop yields - Identification of crops and varieties that are adapted to specific growing conditions - Evaluation of crop growth models - Farms of the Future -Exchange of genetic material and collaborative research
  25. Farms of the Future Identification of sites to hold an interchange between agriculturalist and share climate adaptation techniques and experiences The Climate Analogues concept in the field
  26. Possible analogues BACKWARD •Where can I find the future climate of my site today? MY SITE (future) OTHER SITE (s) (current)
  27. –Different combinations of variables •Temperature and precipitation •Temperature only •Precipitation only •Combinations with bioclimatic variables (Rainfall total, temperature of hottest month…) –Growing period of interest: entire year, specific growing season, rainy season… –Thresholds and GCM agreement: i.e the closest 5/10/15 and where 60/70/80 % of GCMs agree –Before selecting a final site we also need to consider socio- economic parameters, infrastructure, cultural boundaries, soils etc. Identifying exchange sites for FOTF
  28. “Which other places currently experience the future projected climate of a reference site, and from which we can transfer climate adaptation and management techniques? Farms of the Future- Tanzania
  29. Reference site: Yamba, Tanzania
  30. Lushoto CCAFS site Morogoro Mwitikilwa Njombe Nyombo Mbinga Farms of the Future in Tanzania Analogue site map
  31. Graphs comparing the future climate at the reference site (Yamba) and the current climate at potential exchange sites  The best analogue sites are those that have a current climate more similar to the future projected climate of the reference site  Producers are taken from the reference site to investigate the selected analogue sites.
  32. Lushoto Mbuzii Yamba Morogoro Mwitikilwa Nyombo Njombe Mbinga Kinole Journey through analogue sites Village visits Starting point Sepukila Village: -Matengo pits: Traditional soil and water conservation technique -Coffee nursery -Stoves Masasi Village: -Water source -Fish pond -Biogas Mtama Village: - Bee keeping -Market value chain social enterprise visit - Input supply Stockists -Weather station visit - Bean trial visit - Tree nursery visit Farms of the Future in Tanzania A journey to possible future conditions of Yamba
  33. Exchange of Genetic Resources How to apply the Climate Analogues approach for the implementation of the TIRFAA project?
  34. How to apply the Climate Analogues approach for the implementation of the TIRFAA project? Senahú, Guatemala (Longitude= -89.779, Latitude= 15.477) Banana: all year round Backwards analysis: Where can I find my future climatic conditions currently? Share the benefits of genetic resources?
  35. How to apply the Climate Analogues approach for the implementation of the TIRFAA project? Rubaya, Uganda (Longitude= 30.675, Latitude= -0.441) Banana: all year round Forwards analysis: Where can I find my current climatic conditions in the future?
  36. How to apply the Climate Analogues approach for the implementation of the TIRFAA project? Rubaya, Rwanda (Longitude= 30.675, Latitude= -0.441) Banana: all year round Forwards analysis: Where can I find my current climatic conditions in the future?
  37. - Helps to improve the selection of future plant varieties and identify which varieties have proven to be most adaptable to the given climatic conditions. - Construct scenarios for users to observe the opportunities to improve access to genetic materials from outside of their country. - Identify which plant varieties may be most useful for other parts of the world to fulfil the needs to adapt to changing climatic conditions. - Identify areas where there is urgent need to conserve specific genetic materials. Climate Analogues & TIRFAA
  38. A few more words… •There still exists significant uncertainty in future climate projections and their impacts on agricultural systems, especially at the local level. •Until now, the adaptation capacity of communities has been a factor that has rarely been taken into account in global policies
  39. The use of Climate Analogues significantly improves knowledge of possible management techniques under changing climatic conditions, and supports the identification of appropriate adaptation strategies.
