Temperature is a key constraint on ecosystem respiration but is typically measured at only one or a few points across a study site. Given the exponential relationship between temperature and respiration, small differences in temperature across a heterogeneous ecosystem may result in large differences in respiration fluxes. These differences are not captured in current respiration models which use

The nitrogen cycle and its effect on carbon uptake in the terrestrial biosphere is a recent progression in earth system models. As with any new component of a model, it is important to understand the behaviour, strengths, and limitations of the various process representations. Here we assess and compare five land surface models with nitrogen cycles that are used as the terrestrial components of so

We estimated the CH4 budget in Finland for 2004–2014 using the CTE-CH4 data assimilation system with an extended atmospheric CH4 observation network of seven sites from Finland to surrounding regions (Hyytiälä, Kjølnes, Kumpula, Pallas, Puijo, Sodankylä, and Utö). The estimated average annual total emission for Finland is 0.6 ± 0.5 Tg CH4 yr−1. Sensitivity experiments show that the posterior biosp

Providing sufficient food for a growing global population is one of the fundamental global challenges today. Crop production needs not only to be increased, but also remain stable over the years, in order to limit the vulnerability of producers and consumers to inter-annual weather variability, especially in areas of the world where the food consumed is mainly produced locally (e.g. Sub Saharan Af

Payments are central for society. Historically, it involved two parties exchanging goods and services for money. Today, payments, with increasing frequency, consist of digital representations of money that are transferred through globally intertwined network. Payments involve many parties such as payers, payment services providers, banks, central banks, telecom operators, mobile handset manufactur

During the last two decades or so, film support, film policy and the public financing of audiovisual production in Scandinavia and particularly Sweden have undergone extensive transformation. In diverse ways, these changes can be seen as responses to globalization, to increased sub-national regional independence as well as to the emerging idea of nurturing ‘creative industries’ taking hold. They m

This systematic literature review investigates the extent towhich recent anti-corruption literature goes beyond the established paradigms (i.e., principal-agent perspective,macro-level, structural, and legal centralistic approaches) to focus on society’s informal norms, everyday micro-le-vel power relations and non-monetary currencies (e.g.respect, prestige, social status and trust). By reconceptu

With rising powers on the global scene, foreign policy decisions are shaped by multiple theories of rationality. Culture and national identity are increasingly essential in actors’ decisions and play a significant role in foreign policy. This paper examines foreign policy rationality through the lenses of realism and constructivism, applying Mearsheimer and Rosato’s process-oriented definition of

Addressing the questions of this panel, this presentation critically examines the expanding extractivist frontiers in North Africa, driven by narratives of green transitions sustainable development. It explores the complex dynamics between renewable energy projects and local contestations led by environmental defenders and self-determination movements. The rapid growth of wind and solar infrastruc

The current global food system is characterized by anonymity in the value chain, global food trade, loss of knowledge about food sources, and a distant producer-consumer relationship. In addition, the negative environmental impacts of the agricultural sector, such as pollution, degradation of soil and water quality, loss of biodiversity, and significant greenhouse gas emissions, make this sector a

The large-scale mass mobilizations and colossal demonstrations of the last decade have shown that digital and social media platforms, globally, now play significant roles in early formation and further facilitation of activist movements, interested in progressive causes and societal changes. However, the repercussions of the very same events have also clearly shown the shortcomings of mediatized a

Snowpack atop sea ice plays a vital role in the Arctic heat and energy balance by reducing the energy transfer between the atmosphere and the ocean. This study presents an improved snow depth retrieval model over Arctic multiyear ice (MYI) from the Microwave Radiometer Imager (MWRI) data of the Fengyun-3 (FY-3) series satellites using the optimal machine learning approach identified. Validation ag

This paper explores the evolving landscape of regional innovation policy, focusing on the interplay between traditional cluster policies and emerging transformative agendas. Over the past decade, policy initiatives aimed at fostering place-based, collaborative innovation have proliferated. However, questions arise regarding the adequacy of existing policy tools in accommodating newer, transformati

Low vaccination coverage against SARS-CoV-2 (COVID-19) is a public health concern. The aim of this study was to identify barriers and motivators associated with COVID-19 vaccination and develop a vaccine acceptance scoring system. From the overall population residing in Skåne county Sweden in 2022 (n = 1 384 531), 3600 randomly selected individuals (aged ≥18 years) received a survey. Questions wer

Chlorophyll-a (Chl-a) is one of the critical water quality indicators that shows the eutrophication status of aquatic ecosystems. As the largest lake and a well-known attraction in middle Europe, Lake Balaton contributes 70 % or more of local economy through tourism, while also maintaining a unique biodiversity. Therefore, long-term monitoring of water quality is essential for its effective manage

This study investigates isoprene emissions in a high-latitude Alpine tundra ecosystem, focusing on using near-field remote sensing of surface temperatures, the photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI), and meteorological measurements to model these emissions. Isoprene is a key biogenic volatile organic compound (BVOC) emitted by select plants, which c

Universities, operating at the intersection of state, market, and civil society, are increasingly called upon to address urgent global challenges, such as climate change, inequalities, and social injustice. This has given rise to hybrid roles for scholars, ranging from public intellectuals to policy advisers and academic entrepreneurs. Among these roles, scholar-activism stands out by explicitly a
