As the volume and complexity of natural system sensor data grow, an increasing need emerges for advanced predictive modeling, knowledge discovery, and explainable decision-making in environmental monitoring contexts. This research develops advanced machine learning approaches to estimate environmental parameters from increasingly complex sensor data. By focusing on precision, interpretability, and robustness, the project spans multiple sensing modalities from proximal soil sensors to remote laser scanning of forests. In pedometrics and soil science, the work advances tabular regression and deep learning models for digital soil mapping. For forestry applications, the research develops deep learning methods for processing laser scanning point cloud data to estimate forest plantation biometrics. Across both domains, the research emphasizes predictive precision, robust uncertainty quantification, and interpretability of results. This integrated approach contributes to improved environmental parameter estimation, supporting more reliable agricultural and environmental decision-making.

Trees outside of forests (TOF) play a critical role in biodiversity, cultural heritage, and landscape connectivity, especially in intensive agricultural areas and agroforestry systems. However, these trees are often neglected in conventional monitoring approaches, which tend to focus on forests or urban trees. This project aims to develop a robust methodology to map and classify TOFs, providing researchers, ecologists, and policymakers with better insight into their spatial distribution and structural characteristics. By integrating multisensor remote sensing data with state-of-the-art deep learning techniques, this project seeks to create a scalable tool for improving landscape-level assessments and supporting evidence-based decision-making.

Agriculture, forestry and the food system play a major role in the global greenhouse gas (GHG) balance. This results in the need for adjustments to agricultural practice to meet the 2030 Climate Action Program while increasing resilience to weather extremes and other impacts of global warming. One approach for reducing GHG emissions and adopting agriculture to climate change are agroforestry systems, which are characterised by the spatial integration of trees (especially fruit, fast
growing or timber trees) and field crops.
The main objective of this PhD project is to develop and investigate suitable methods for monitoring and assessing biodiversity in agroforestry systems by combining high spatial resolution multispectral and LiDAR data from Unmanned Aerial Vehicles (UAV) systems. This should be done by an integrated AI analysis of geometric and spectral UAV data using machine learning to derive high-resolution bio-physical and bio-chemical plant properties in agroforestry systems. These parameters form the basis for a 3D modelling of biomass in arable and tree strips (yield/biomass/carbon monitoring). In addition, multi-temporal data (summer/winter) are combined in order to be able to integrate additional information from different tree conditions (leafy/non-leafy) for biomass modelling.
Finally, the analysis of the interaction of tree strips/landscape elements and arable crops, as well as the mapping of CO2 storage as a function of above-ground biomass and site factors must be of interest.

AI models can be trained on a variety of data, such as sensor data, satellite data, genomic data, image data, weather data, and climate data. This can be used in the context of different applications and several use cases in the bioeconomy domain, e.g., for improving performance regarding disease detection on plants, precise plant monitoring, smart water use, and optimizing waste recycling processes. Such models can then help, for example, to detect pests, identify weeds, and optimize the use of fertilizers and pesticides. Although those AI models learn complex relationships between different components in the bioeconomy, those relations typically remain hidden within the often called black box model, leading to no or only poor knowledge about the underlying connections of the driving factors in the input data. Here, the field of explainable AI (XAI) has emerged, with the aim to provide insights into the decision-making strategies and to showcase the important features and complex relationships the decision is based on. In this project, methods of explainable AI for multimodal data will be developed for explaining AI models trained on multimodal data with applications in the bioeconomy. With the novel XAI methods we aim to showcase the complex relationships between different types of data, such as genetics, soil composition, weather, and climate data, learned by the AI model. We aim to contribute to the generation of novel knowledge that tackles the enormous challenge of an efficient realization of the bioeconomy.
