Final Report Abstract

The objective of the Crop-SIF project was to study crop productivity and yield variability by making use of recent developments related to satellite vegetation observations and data mining in the context of ensuring food security. Crop-SIF activities dealt with both the machine learning and deep learning methods applied to both vegetation and meteorological data, as well as the utilization of - only recently quantified from satellite platforms - sun-induced chlorophyll fluorescence (SIF). This research contributed to the assessment of agricultural productivity and climate impacts by taking advantage using novel methodologies (interpretable deep learning), datasets (SIF) and computing platforms (Google Earth Engine). In addition, within the project, the cooperation between GFZ German Research Centre for Geosciences and the Nanjing University was strengthened, including exchange visits of the scientists from both research institutions.
