Calculation of agro climatic factors from global climatic data

  1. 1. Agro-climatic factors – a puzzle piece in regional food supplies forecasting - final report on challenge #13 - Pavel Hájek, Raitis Berzins, Jiří Valeš, Martin Pitoňák, Vincent Onckelet, Tomáš Andrš, Veronika Osmiková, Ronald Ssembajwe, Amit Kirschenbaum, Jörg Schliesser, Michal Kepka & Karel Jedlička
  2. 2. Paradox of contemporal agriculture
  3. 3. Paradox of contemporal agriculture • Transforming data in information, knowledge and wisdom (DIKW) • Data are facts • Information adds context by descriptions • Knowledge adds structure • Wisdom brings objective reasoning
  4. 4. Paradox of contemporal agriculture • Three steps of effective and sustainable crop cultivation: • select the right crop for a particular place • intervene in the field just in the very necessary cases • intervene in an effective way, when intervening Reasonable yield, whilst sustainable farming
  5. 5. Our story • a farmer examining • a suitability of particular place • for a particular plant • using relevant data • up to date technology
  6. 6. Place
  7. 7. Place described by agro-climatic factors
  8. 8. Agro-climatic factors • Temperature related • frost-free periods • growing degree units • heat stress units • number of (optimal) growing degree days • Soil temperature related • nitrogen application window • Incident sunlight related • accumulated solar radiation • Precipitation, evapotranspiration and runoff related • water balance
  9. 9. Frost-free period
  10. 10. Frost-freeperiod
  11. 11. Growing degree units, days, heat stress
  12. 12. Nitrogen application window
  13. 13. Accumulated solar radiation
  14. 14. Water balance Precipitation Water absorbed by roots Evaporation Transpiration Groundwater recharge Run off
  15. 15. Plant
  16. 16. Plant compared to Place Models of a plant • Ideal growth stages • Growing degree units needed • Solar exposure needed • Water needed • Nutrients needed Agro-climatic factors • Growing degree units • Solar radiation • Water balance • Fertilization (nitrogen application)
  17. 17. data
  18. 18. ERA 5-Land data quality? • annual temperature uncertainty • std. dev.= 0.03 °C. • min = - 0.33 °C, • max = 0.44 °C,
  19. 19. ERA 5-Land data quality?
  20. 20. ERA 5-Land data quality? • Differences ERA5-Land to in-situ sensor • standard dev. = 1.06 °C • min = −3.06 °C • max = 3.8 °C.
  21. 21. technology
  22. 22. Technology used • Algorithms available (bit.ly/agro-climatic-factors) • EUXDAT e-infrastructure (test.euxdat.eu) • Jupyter Notebooks, CDS, paralelization using HPC
  23. 23. Frost free period calculation
  24. 24. Agro-climatic factors visualization
  25. 25. Thank you for listening our story of • a farmer examining • a suitability of particular place • for a particular plant • using relevant data • up to date technology On behalf the team Karel Jedlička UWB, WRLS jedlicka.krl@gmail.com https://app.hslayers.org/project-agro-climatic
