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 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.

Eine umfassende, auch wertorientierte Wahrnehmung der Umwelt ist ohne Umweltqualitaetsziele nicht moeglich. Blosse Gefahrenabwehr oder Sanierung kommen notfalls noch ohne weiterfuehrende Vorstellungen ueber eine Umwelt, in der nachhaltig die Umweltvertraeglichkeit der Raumstrukturen und -funktionen und die Lebensqualitaet der Menschen gewaehrleistet wird, aus. Dagegen bedarf eine Umweltvorsorge, bei der weitere schaedigende und belastende Umwelteinfluesse nicht nur verhindert, sondern die vorhandene Umwelt auch verbessert werden soll, raeumlich, zeitlich und sachlich differenzierter Umweltqualitaetsziele. Diese werden als regional differenzierte Stes erarbeitet und der Entwicklungsprozess prototypisch aufbereitet. Mit den gewonnenen Ergebnissen, die auch ueber Datenbanken verfuegbar sein werden, koennen Staedte und Gemeinden den Einsatz dieses Instrumentes beschleunigen und versachlichen.
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).

Soil structure determines a large part of the spatial heterogeneity in water storage and fluxes from the plot to the hillslope scale. In recent decades important progress in hydrological research has been achieved by including soil structure in hydrological models. One of the main problems herein remains the difficulty of measuring soil structure and quantifying its influence on hydrological processes. As soil structure is very often of biogenic origin (macropores), the main objective of this project is to use the influence of bioactivity and resulting soil structures to describe and support modelling of hydrological processes at different scales. Therefore, local scale bioactivity will be linked to local infiltration patterns under varying catchment conditions. At hillslope scale, the spatial distribution of bioactivity patterns will be linked to connectivity of subsurface structures to explain subsurface stormflow generation. Then we will apply species distribution modelling of key organisms in order to extrapolate the gained knowledge to the catchment scale. As on one hand, bioactivity influences the hydrological processes, but on the other hand the species distribution also depends on soil moisture contents, including the feedbacks between bioactivity and soil hydrology is pivotal for getting reliable predictions of catchment scale hydrological behavior under land use change and climate change.
The CRC806-Database platform is the Research Data Management infrastructure of the SFB / CRC 806. The infrastructure is implemented using Open Source software, and implements Open Science, Open Access and Open Data principles. The Collaborative Research Centre (CRC; ‘Sonderforschungsbereich’ or SFB) is designed to capture the complex nature of chronology, regional structure, climatic, environmental and socio-cultural contexts of major intercontinental and transcontinental events of dispersal of Modern Man from Africa to Western Eurasia, and particularly to Europe (Cited from introductory text on: www.sfb806.de).
