In March 2022, an initial mission to CIAT (Cali, Colombia) allowed the collection of hyperspectral images (HSI) from 31 cassava genotypes. The results of these experiments enabled the development of an initial calibration to predict the distribution of dry matter at the scale of a cassava root slice, highlighting significant variations between genotypes. Thanks to this success, CIAT decided to invest in a hyperspectral camera in 2023 and requires training in HSI methods for its post-harvest cassava quality team. The objective of the mission of November 2023 is therefore to provide such training, within the framework of strengthening geo-partnership skills. After this training mission, the second mission to CIAT of May 2024 aimed to support the post-harvest cassava quality laboratory team in characterizing the cooking quality of 133 cassava varieties using HSI. This mission provided an opportunity to verify the practical application of the knowledge and skills acquired by the team during the previous mission.
