Postharvest Loss Estimates for Cereals and Crops: A Practical Guide

Explore APHLIS website to access science-based estimates of postharvest losses for cereals and crops using an interactive calculator tool in Excel. Discover how to input location-specific data, select crop and climate zones, and obtain quality estimates for different harvest seasons. The APHLIS Calculator allows users to customize figures and make informed decisions to reduce postharvest losses effectively.

Presentation Transcript

1. APHLIS Postharvest loss estimates for cereals and other crops

2. The downloadable APHLIS calculator

3. www.aphlis.net

4. You want to know how much cereal grain is lost? Science-based reasonable estimates are presented in interactive maps or in tables on the APHLIS website: www.aphlis.net This presentation is about the Downloadable Calculator that you can use to estimate the magnitude of losses at: different links in the postharvest chain different harvest seasons for your focal area and crop, and you can also obtain information on the quality of these estimates www.aphlis.net | Postharvest loss estimates for cereals and other crops

5. From the APHLIS website: www.aphlis.net

6. Once downloaded, the APHLIS Calculator opens in Excel

7. Navigation buttons All figures in red can be changed: the user enters values for their location www.aphlis.net | Postharvest loss estimates for cereals and other crops

8. www.aphlis.net | Postharvest loss estimates for cereals and other crops

9. Enter your data: Select crop and climate zone www.aphlis.net | Postharvest loss estimates for cereals and other crops

10. www.aphlis.net | Postharvest loss estimates for cereals and other crops

11. Your location, and the year of interest Specify the crop and the climatic zone

12. www.aphlis.net | Postharvest loss estimates for cereals and other crops

13. Enter your data: Seasonal data for your location Size of the farms Up to 3 seasons www.aphlis.net | Postharvest loss estimates for cereals and other crops

14. Up to 3 seasons in the year www.aphlis.net | Postharvest loss estimates for cereals and other crops

15. Figures for small and large scale farms www.aphlis.net | Postharvest loss estimates for cereals and other crops

16. Quantities harvested, % marketed without storage.. rain at harvest or during drying, duration of storage presence of the LGB pest www.aphlis.net | Postharvest loss estimates for cereals and other crops

17. www.aphlis.net | Postharvest loss estimates for cereals and other crops

18. See the results: Estimated losses for the value chain, for each harvest and for type of farm; overall

19. Steps of the value chain with % loss at each step: PHL Profile

20. Seasons Grain remaining at each step of the value chain and associated loss increment www.aphlis.net | Postharvest loss estimates for cereals and other crops

21. % grain remaining and % loss www.aphlis.net | Postharvest loss estimates for cereals and other crops

22. Annual % loss www.aphlis.net | Postharvest loss estimates for cereals and other crops

23. Play and learn: Adjust the default figures to simulate different scenarios in order to get a better understanding of the different factors influencing losses www.aphlis.net | Postharvest loss estimates for cereals and other crops

24. See the results: Estimated losses are also expressed in weight www.aphlis.net | Postharvest loss estimates for cereals and other crops

25. Grain remaining and losses expressed in weight www.aphlis.net | Postharvest loss estimates for cereals and other crops

26. Visualise the results: Estimated losses shown in graphs

27. % loss by harvest and broken down by value chain step

28. Overall % grain remaining and % loss

29. Overall % loss for farm type and by value chain step

30. Assess the quality of estimates: Reliability of the data used in calculations of loss estimates www.aphlis.net | Postharvest loss estimates for cereals and other crops

31. In green: loss estimated from published data specific to these circumstances and measured In red: loss estimated from published non- specific data or from questionnaires www.aphlis.net | Postharvest loss estimates for cereals and other crops

32. Access the references: Details of the published scientific literature used are also provided www.aphlis.net | Postharvest loss estimates for cereals and other crops

33. ID number of publications Full details available in the calculator from the button % loss reported by each publication and overall average www.aphlis.net | Postharvest loss estimates for cereals and other crops

34. Lastly, the APHLIS calculator provides a table to add up postharvest losses for several commodities in the location www.aphlis.net | Postharvest loss estimates for cereals and other crops

35. Add the loss figures provided by the calculator for each of the crops of interest www.aphlis.net | Postharvest loss estimates for cereals and other crops

36. APHLIS+ is a 5 years project to make APHLIS even better. It is funded by: The future of APHLIS www.aphlis.net | Postharvest loss estimates for cereals and other crops

37. To improve APHLIS, the Bill & Melinda Gates Foundation has funded the new APHLIS+ project APHLIS+ will: Increase the type of crops covered Improve the accuracy of the estimation model Add estimates of value and nutritional losses Update the user interface Add warning systems on risks of LGB or aflatoxin Further develop the network of experts www.aphlis.net | Postharvest loss estimates for cereals and other crops
