Spatial heterogeneity and substrate availability as limiting factors for subsoil C-turnover

In subsoils, organic matter (SOM) concentrations and microbial densities are much lower than in topsoils and most likely highly heterogeneously distributed. We therefore hypothesize, that the spatial separation between consumers (microorganisms) and their substrates (SOM) is an important limiting factor for carbon turnover in subsoils. Further, we expect microbial activity to occur mainly in few hot spots, such as the rhizosphere or flow paths where fresh substrate inputs are rapidly mineralized. In a first step, the spatial distribution of enzyme and microbial activities in top- and subsoils will be determined in order to identify hot spots and relate this to apparent 14C age, SOM composition, microbial community composition and soil properties, as determined by the other projects within the research unit. In a further step it will be determined, if microbial activity and SOM turnover is limited by substrate availability in spatially distinct soil microsites. By relating this data to root distribution and preferential flow paths we will contribute to the understanding of stabilizing and destabilizing processes of subsoil organic matter. As it is unclear, at which spatial scale these differentiating processes are effective, the analysis of spatial variability will cover the dm to the mm scale. As spatial segregation between consumers and substrates will depend on the pore and aggregate architecture of the soil, the role of the physical integrity of these structures on SOM turnover will also be investigated in laboratory experiments.

The scalar organization of environmental governance: an institutionalist perspective on the transformation of water and marine governance in the European Union

The project aims to theorize the scalar organization of natural resource governance in the European Union. This research agenda is inspired by critical geographers' work on the politics of scale. The research will examine an analytical framework derived from theories of institutional change and multi-level govern-ance to fill this theoretical gap. Furthermore, it will review conceptualizations of the state in institutional economics, evaluate their adequacy to capture the role of the state in the dynamics identified, and develop them further. The described processes may imply shifts in administrative levels, shifts in relations between different levels and changes in spatial delimitations of competent jurisdictions that result, for example, from decentralization or the introduction of river basin oriented administrative structures. The research investigates the implications of two European Directives: the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). They both have potentially great significance for the organization of marine and water governance at the level of Member States and below, and adhere to similar regulatory ideas for achieving good ecological status of waters. A multiple case study on changes in the scalar reorganization of marine and water governance that result from the implementation of the Directives will be carried out. It will rely on qualitative and quantitative data gathering based on semi-structured interviews and review of secondary and tertiary sources looking at Portugal, Spain, and Germany. It specifically addresses the role of social ecological transactions, the structure of decision making processes and the role of changes in contextual factors (such as ideologies, interdependent institutions and technology).

Germany Mosaic: A Multi-Decadal Remote Sensing Time Series of Germany, 1984–2025

The Germany Mosaic is an analysis-ready spatiotemporal dataset with a consistent data-cube structure, covering the entire territory of Germany from 1984 to 2025. It provides consistently processed Landsat-based raster and vector products on a common spatial grid, enabling long-term analysis of environmental and landscape dynamics as well as machine-learning and AI-based applications. For each year, two seasonal six-band multispectral composites are provided, representing the periods May–July and August–October. All usable Landsat observations acquired within the respective seasonal period are included in the compositing process to maximize spatial coverage and minimize cloud contamination, resulting in virtually cloud-free seasonal image composites. The spatial organization is consistent across the complete time series: all years use the same pixel size, spatial grid, tile geometry, band structure, and variable schema for the vector products. Germany is represented by 54 overlapping tiles of 120 × 120 km with a 20 km overlap. This standardized structure enables direct spatial and temporal comparison across more than four decades without additional spatial harmonization or restructuring. In addition to the multispectral raster data, the dataset contains image-segmentation polygons (“zones”) representing approximately homogeneous image regions, together with associated spectral, textural, statistical, geometric, and contextual attributes. The vector datasets include 32 attributes covering seasonal spectral information, vegetation indices, temperature, image quality, texture and variability measures, Rao’s diversity, elevation-related information, and indicators concerning the form, size, connectivity, distribution, and spatial relationships of the zones. Additional raster products provide elevation data and statistics for seasonal vegetation change. The consistent data-cube structure makes the Germany Mosaic particularly suitable for large-scale time-series analysis, change detection, environmental monitoring, machine learning, and other AI-based workflows. It can also provide a data foundation for environmental modelling and digital-twin applications. This dataset constitutes the second version and continuation of the previously published Germany Mosaic 1984–2023 dataset (DOI: 10.1594/PANGAEA.967266) and extends the temporal coverage through 2025 while introducing a revised and standardized spatial organization based on 54 consistently defined tiles, a 20 km overlap between the tiles, and new raster and vector features.
