Macronutrients in tree stems and foliage: a comparative study of six temperate forest species planted at the same sites

Common European tree species ( oak, ash, beech, birch, lime and spruce) planted in adjacent stands on six sites were compared in terms of macronutrient concentrations in foliar and stem wood ( including bark) biomass. The nutrient concentrations in both biomass compartments were much more dependent on species than on site although soil conditions differed between the sites. Differences between species regarding stem wood nutrient concentrations only partly corresponded to the differences in species foliage. The concentrations in spruce were considerably lower than in deciduous species, except P in foliage, and Ca in both stem wood and foliar biomass. Differences were also observed between the deciduous species both regarding foliar and stem wood nutrient concentrations. The differences should be considered when modelling nutrient circulation in forest stands and when evaluating the long-term sustainability of forest management

Corruption Risks in Renewable Resource Governance: Case Studies in Iceland and Romania

In this research, we attempt to shed light on the question of where corruption risks in the governance of renewable resources are located and how they have been addressed in European countries that have different levels of corruption. A comparative case study design was chosen, looking into the fisheries sector in Iceland and the forestry sector in Romania. We conducted 25 semi-structured interviews with various stakeholders sampled through a snowball method. Qualitative coding and systems analysis were used to analyse the interviews. The results indicate that comprehensive and ambitious legislation does not necessarily translate into successful resource governance systems. In general, the institutions that were put in place to enforce and monitor the legal codes and regulations did not have the capacity to carry out their role. Additionally, interviewees were generally found to have a widespread perception of there being a corrupt relationship between politics and big companies operating in their sectors. Our findings suggest that when people hold such perceptions, it undermines anti-corruption policy efforts in the resource sectors, which can then impede sustainable resource management

Economies of scale and perceived corruption in natural resource management : A comparative study between Ukraine, Romania, and Iceland

Funding Information: Funding: This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska‐Curie grant agreement No 675153. Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland.The aim of this paper is to enhance understanding of factors that undermine sustainable management of renewable resources by identifying and analyzing the main drivers and dynamics involved, with a focus on the role of corruption perceptions and its implications. To shed light on the research question, we chose to perform a comparative study of three different resource sectors in European countries that are ranked differently on the Corruption Perception Index by Transparency International, namely fisheries in Iceland, forestry in Romania, and arable soils in Ukraine. We conducted 40 in‐depth semi‐structured interviews with various stakeholders to explore assumptions on individual actions and behavior in the sectors. The interviews were analyzed using a qualitative coding procedure based on causal loop diagrams, a method from system dynamics. The results indicate that even though the cases are different, they share a similar outcome, in that privatization of the resource and consolidation of companies took place, along with perceived risk of both unsustainable resource management practices and corruption. Our findings suggest that the underlying similarities of the cases are that privatization occurred around the same time in early 1990s, when neoliberal economic ideology influentially held up the idea that private ownership meant better management. What followed was a transition to economies of scale that ultimately resulted in dominance of large vertically integrated companies in the sectors. The resulting inequalities between large and small actors in the renewable resource management systems serve to increase the risk for unsustainable management decisions as well as increase perceptions of corruption risks, especially amongst smaller actors in the sectors.Peer reviewe

Transparency and Leverage Points for Sustainable Resource Management

Publisher Copyright: © 2022 by the authors.The phrase ‘sunshine is the best disinfectant’ is commonly used to suggest that transparency can counter corruption and ensure accountability. In the policy world, several analytical tools have been developed to obtain information on what policy decision would bring about the biggest positive effect for the least amount of effort. There is a tendency to view transparency as the silver bullet in that respect. This paper aimed to shed light on how measures of transparency can serve as a leverage point for sustainable resource management. We begin by analysing the concept of transparency and then draw from Donella Meadows’ work on leverage points to analyse the transformative potential of increasing transparency towards sustainable resource management. We then demonstrate the use of this analytical approach by applying it to three case studies on resource management systems in Ukraine, Romania, and Iceland. The results suggested that transparency in resource management needs to be accompanied by widely accepted standards and accountability mechanisms for it to serve as an effective leverage point. If these factors are neglected, the credibility of transparency can be undermined. Prioritising transparency as a policy intervention to alleviate corruption risks, in the absence of accountability mechanisms and clear rules, might be misplaced, and require deeper leverage points.Peer reviewe

Barriers and bridges for sustaining functional habitat networks: A macroecological system analysis of wet grassland landscapes

This study aims at supporting the maintenance of representative functional habitat networks as green infrastructure for biodiversity conservation through transdisciplinary macroecological analyses of wet grassland landscapes and their stewardship systems. We chose ten north European wet grassland case study landscapes from Iceland and the Netherlands in the west to Lithuania and Belarus in the east. We combine expert experiences for 20–30 years, comparative studies made 2011–2017, and longitudinal analyses spanning >70 years. Wader, or shorebird, (Charadrii) assemblages were chosen as a focal species group. We used evidence-based knowledge and practical experience generated in three steps. (1) Experts from 8 wet grassland landscapes in northern Europe's west and east mapped factors linked to patterns and processes, and management and governance, in social-ecological systems that affect states and trends of wet grasslands as green infrastructures for wader birds. (2) To understand wader conservation problems and their dynamic in wet grassland landscapes, and to identify key issues for successful conservation, we applied group modeling using causal loop diagram mapping. (3) Validation was made using the historic development in two additional wet grassland landscapes. Wader conservation was dependent on ten dynamically interacting ecological and social system factors as leverage points for management. Re-wetting and grazing were common drivers for the ecological and social system, and long-term economic support for securing farmers’ interest in wader bird conservation. Financial public incentives at higher levels of governance of wetland management are needed to stimulate private income loops. Systems analysis based on contrasting landscape case studies in space and over time can support (1) understanding of complex interactions in social-ecological systems, (2) collaborative learning in individual wet grassland landscapes, and (3) formulation of priorities for conservation, management, and restoration.publishedVersio

Managing Forestry in a Sustainable Manner : The Importance of System Analysis

This chapter examines from systems and livelihood perspectives, with Nemoral and Boreal forest zones of the Global North and Sweden as examples, how forestry may meet current and future sustainability challenges both as a traditional resource base and with respect to other ecosystem services. Previous and current forest policy/governance is briefly described against the background that Swedish forestry is based both on huge holdings by few industrial owners as well as on a multitude of small individual, often family owned, forest estates. Successful delivery against environmental objectives will require careful balancing of interests and the active participation of local forest owners. Cumulative effects of old and new societal demands on forestry and their impact on local livelihoods poses in this respect a systemic risk as economic and social sustainability often gets limited consideration. There is a need for a more synoptic and systemic analysis of how forestry is affected by multiple, partly contradictory, demands from an increasing array of stakeholders, in order to enable a move towards a biobased economy. Stakeholder-based group modelling is a potentially powerful analytic and conflict reducing approach that could help improve forestry’s contribution to the acute need to handle the climate change and current sustainability challenges.open access</p

Micronutrient levels in some temperate European tree species: a comparative field study

Micronutrient concentrations in foliage and stemwood (including bark) of six European tree species (Betula pendula Roth., Quercus robur L., Fraxinus excelsior L., Fagus sylvatica L., Tilia cordata Mill. and Picea abies (L.) Karst.) planted on the same type of soil at six sites in three different countries were studied. Micronutrient concentrations in foliage were considerably higher than in stemwood for all elements and species studied, except for Fe in spruce. Interspecies comparisons revealed significant differences in concentrations both in foliar and stemwood biomass, as well as in stemwood:foliage nutrient ratios. Lime foliage showed a considerably higher concentration of B than all other species, while the stemwood concentration of this element was highest in ash. Mn concentration in both foliar and stemwood biomass of ash was extremely low compared with concentrations in other species. Birch stemwood showed nearly double the level of Zn in other species at all sites. Zn concentrations in the birch foliage were also higher than in other species, with the exception of the Lithuanian sites, which showed lower EDTA-extractable Zn concentrations in the soils. The concentration of Cu was lowest in spruce foliage, while Cu concentrations in stemwood were similar in all species. It was concluded that species-related differences in microelement nutrition must be taken into account when evaluating the nutrient status of common European forest tree species, and when using them as bio-indicators of the effects of environmental pollution
