    This systematic review focuses on the role of renewable energy in shaping the future of the European energy system. It explores the scientific renewable energy scenarios and offers insights into how broadly European-level scenarios have scanned future energy landscapes and the types of utilised scientific knowledge amid geopolitical tensions. To explore the dimensions of the scenario studies, the analysis applies the PESTE framework, which reflects the results on multidisciplinary three perspectives framework for the energy transition. The results underscore a prevailing positivist paradigm in scenario studies of energy transition, conceptualising it as a future characterised by inevitable advancements in techno-economic drivers while other societal as well as biophysical elements tend to play a minor role. However, it is evident that this approach has not been, and will not be in the future, capable of anticipating implications of geopolitical disruptions of the kind witnessed in recent years, for instance. Consequently, there should be more scenario studies based on disciplinary insights beyond techno-economic drivers to increase the understanding of the future of renewable energy. Indeed, there is still an engagement gap in how to effectively deepen dialogue between different disciplines in scenario studies to best describe the energy transition.

  • Building food system resilience: insights from Finland using causal loop diagrams

    Ecology and society : 2 (Resilience Alliance, 2026)
    The resilience of European food systems is being put to the test by complex and unexpected shocks, disruptions, and discontinuities, recent examples of which include COVID‑19 and the Russian invasion of Ukraine. Owing to the complexity of the food system and the high degree of interdependence within it, the impacts of disruptions reverberate throughout the system, exposing vulnerabilities that were poorly recognized before the crisis. These cascading effects highlight the need to understand system‑wide interconnections and to develop adaptive capacities that strengthen resilience under conditions of uncertainty. This study identifies the key variables that affect the ability of the Finnish food system to secure desired outcomes, as well as the key measures that can enhance its resilience. To achieve this, we interviewed nine experts on the Finnish food system and conducted a qualitative analysis to construct causal loop diagrams that visualize the system’s dynamic interactions. These diagrams were further refined and validated during a researcher workshop. Building on this process, we identified four interlinked sub‑systems, i.e., systems thinking and cooperation, flourishing rural areas, profitable and sustainable primary production, and diversified input and food markets, which shape resilience through distinct feedback mechanisms. Six key measures emerged as central to strengthening resilience: improved supply pool coordination, resilience‑inspired policymaking, revitalization of rural areas, improved profitability, increased crop diversity, and reduced reliance on imported inputs. Together, these findings underscore the importance of systemic, cross‑sectoral approaches that go beyond static indicators and address the dynamic nature of food system resilience.

    There is limited understanding on how complex interdependencies among large herbivore grazing, competitive and facilitative interactions among plants, and the changes in temperatures and precipitation shape northern boreal and subarctic ecosystems. Here, we assessed changes in dwarf shrub and lichen cover and height using data from 617 field sites monitored a decade apart (2005–2008 and 2016–2018) in semi-dry and dry habitats in northernmost Finland, where reindeer herding constitutes a traditional livelihood with reindeer moving freely across landscapes and grazing on seasonally available forage plants. We hypothesized that several direct and indirect factors related to climate and reindeer herding regimes drive changes in vegetation. We predicted that over the 10 years, shrub cover and height would increase and that lichen cover and height would decrease in response. We also expected that the decline in lichen cover and height would be more pronounced in summer-grazed areas and in areas with higher reindeer densities. We observed that shrub cover and height had increased drastically, and the change in lichen cover was negatively correlated with change in shrub cover. However, the change in lichen height was positively correlated with change in shrub height, which reveals a dual relationship between dwarf shrub and lichen vegetation. The seasonal timing of reindeer grazing was also important: lichen cover decreased less in winter than summer and year-round ranges. The direction of the change in lichen height was even opposite among seasonal ranges with decreased height in summer and year-round ranges and increased height in winter ranges. Lichen cover and height responded negatively to higher reindeer densities in both summer and winter ranges. While shrub cover had increased in summer and year-round ranges, shrub cover was unchanged in winter ranges, and shrub height increased less with increasing reindeer densities. These results indicate that reindeer grazing may partially counteract “shrubification” in areas that are grazed only during winter. Our results demonstrate how differing large herbivore grazing regimes, together with their complex interdependencies between climate warming and associated changes in plant–plant interactions, contribute to spatially variable vegetation trajectories. Due to the direct and the indirect mechanisms by which climate warming affects dwarf shrub and lichen vegetation, for maintaining good lichen grounds for reindeer herding, the benefit of seasonal range rotation will likely even increase in the future.
