Given the significance of national carbon inventories, the importance of large-scale estimates of carbon stocks is increasing. Accurate biomass estimates are essential for tracking changes in the carbon stock through repeated assessment of carbon stock, widely used for both vegetation and soil, to estimate carbon sequestration. Objectives: The aim of our study was to determine the variability of several aspects of the carbon stock value when the input matrix was (1) expressed either as a vector or as a raster; (2) expressed as in local (1:10,000) or regional (1:100,000) scale data; and (3) rasterized with different pixel sizes of 1, 10, 100, and 1000 m. Method: The look-up table method, where expert carbon content values are attached to the mapped landscape matrix. Results: Different formats of input matrix did not show fundamental differences with exceptions of the biggest raster of size 1000 m for the local level. At the regional level, no differences were notable. Conclusions: The results contribute to the specification of best practices for the evaluation of carbon storage as a mitigation measure, as well as the implementation of national carbon inventories.

This study introduces a novel spatially explicit modeling framework developed to quantify the secondary environmental benefits of groundwater protection strategies in karst landscapes, with a specific application to the Hranice Abyss region. The model employs a multi-criteria decision analysis, integrated with hydrological modeling and a high-resolution random forest-based prediction algorithm, to downscale land surface temperature (LST) in order to obtain high-resolution 1 × 1 m spatial results. The primary contribution of this research lies in its capacity to assess not only the core objectives of groundwater protection but also its wider environmental impacts, including enhanced stormwater retention and the mitigation of land surface temperature increases. Key model predictors include land use and land cover data, and the framework is adaptable across diverse landscape types. In the case study area, water retention capacity demonstrated an increase of up to 30%, with an average rise in precipitation retention of 18.2 mm per microbasin. However, reductions in surface temperature were more modest, with a maximum decrease of 7.3%, corresponding to an average temperature drop of 1.5 °C. The model further identified pronounced seasonal and land-use-specific variations in surface temperature, particularly on agricultural land, where temperature fluctuations reached up to 2.6 °C between pre- and post-harvest periods. The findings of this study offer critical insights into how targeted land-use interventions can not only safeguard groundwater resources but also enhance landscape resilience to climate change. As such, this modeling approach provides an essential tool for the advancement of sustainable water resource management and climate-adaptive environmental planning.
