Incorporating high-resolution climate, remote sensing and topographic data to map annual forest growth in central and eastern Europe

To enhance our understanding of forest carbon sequestration, climate change mitigation and drought impact on forest ecosystems, the availability of high-resolution annual forest growth maps based on tree-ring width (TRW) would provide a significant advancement to the field. Site-specific characteristics, which can be approximated by high-resolution Earth observation by satellites (EOS), emerge as crucial drivers of forest growth, influencing how climate translates into tree growth. EOS provides information on surface reflectance related to forest characteristics and thus can potentially improve the accuracy of forest growth models based on TRW. Through the modelling of TRW using EOS, climate and topography data, we showed that species-specific models can explain up to 52 % of model variance (Quercus petraea), while combining different species results in relatively poor model performance (R2 = 13 %). The integration of EOS into models based solely on climate and elevation data improved the explained variance by 6 % on average. Leveraging these insights, we successfully generated a map of annual TRW for the year 2021. We employed the area of applicability (AOA) approach to delineate the range in which our models are deemed valid. The calculated AOA for the established forest-type models was 73 % of the study region, indicating robust spatial applicability. Notably, unreliable predictions predominantly occurred in the climate margins of our dataset. In conclusion, our large-scale assessment underscores the efficacy of combining climate, EOS and topographic data to develop robust models for mapping annual TRW. This research not only fills a critical void in the current understanding of forest growth dynamics but also highlights the potential of integrated data sources for comprehensive ecosystem assessments.

Europe and Germany's Age of Catastrophe, 1914-1950

Many, many comparisons have been drawn in recent years between the current rise of (right-wing) populism and the financial crisis of 2008 that shook and continues to shake Europe to its core, and the tumultuous and horrifying events of the 1930s, which in the end resulted in the Second World War. A number of recent studies which (partially) focus on this decade carry ominous titles like To Hell and Back, The Age of Catastrophe and The Triumph of the Dark. Referred to by some historians as the second Thirty Years’ War, the period from the First World War to the end of the Second still continues to draw much academic and indeed public attention. In many cases, Germany deservedly plays a central role in the analysis, either in the form of the Kaiserreich or the ill-fated Weimar Republic and, of course, Nazi Germany. The five books under review here discuss European history between 1914 and 1950 in general, and that of Germany in particular, in this period. What do these books tell us about Europe’s and Germany’s path in the first half of the twentieth century, and what new insights do they provide? https://doi.org/10.1177/0265691418777981 LinkedIn: https://www.linkedin.com/in/martijn-lak-71793013/

Legal Transplants: A European Perspective.

Transplantation of regulatory arrangements into the Central Eastern Europe

ABSTRACT: In a global society legal systems tend to become far more intertwined than they have been so far. Transplantation of legal arrangements from one legal system to another became an increasingly important issue as a consequence of growing interdependency among...
