Some previous studies showed that the formation of several deep dark humus-rich topsoils in Northern Europe was strongly influenced by the application of different organic materials by anthropogenic activities in former times. Such topsoils classified as plaggic Anthrosols also occurred in the Jæren region in SW Norway. However, source material and formation time of these Plaggic Anthrosols have not yet been clarified. Close to this region we found further humus-rich topsoils in the Karmøy municipality (2 sites at main island of Karmøy and 1 site at Feøy). These soils show a thick humus-rich topsoil up to 30 cm, and their formation cannot only be explained by natural conditions. We analyzed the molecular signature of the soil organic matter (SOM) by benzene polycarboxylic acids (BPCA), non-targeted bulk SOM mass spectrometry, δ34S and 14C AMS dating in order to determine source materials and the age of the SOM. The black carbon (BC) contents of the plaggic soils in Jæren (mean 3.4 g kg−1) deliver clear evidence for inputs of combustion residues from ancient fire management and/or from settlements. The C-XANES and Py-FIMS-spectra reveal relative enrichments of aromatic C and heterocyclic N compounds in the plaggic soils corresponding to the BC contents. In contrast, the humus-rich topsoils in Karmøy seem to be unaffected by fire management due to the low BC contents (mean 0.6 g kg−1) and the relative low portions of aromatic C and heterocyclic N compounds from C-XANES and Py-FIMS. The δ34S isotope signature of the SOM ranged from 10.6 to 15.2‰ in the soils at the islands and 10.0 to 13.5‰ in Jæren, corresponding to the Anthrosols in the Baltic Sea region (Median: δ34S = 11.5‰) and suggest an input of marine biomass (δ34S of seaweed = 20‰). The AMS 14C dating and complementary archaeological literature implied that the soils in Jæren and Karmøy have been formed between the Roman Iron Age (500 BC to AD 500) and the Viking Age (AD 800 to AD 1,000). Our results provide strong evidence for an anthropo-pedogenesis of the humus-rich topsoils in Karmøy and indicate parallels to the plaggic soils in Jæren as well as to Anthrosols in the Baltic Sea region. Therefore, we propose to classify the humus-rich topsoils in Karmøy as Anthrosols.

The successful transition towards renewable energy (RE) technologies is closely intertwined with various societal aspects. Wind energy (WE) is one of the most controversial RE-types, possibly due to the multiplicity of related public concerns. Although some European country-comparisons exist, research concerning acceptance factors in different political and cultural planning contexts is scarce, especially in Eastern and Southern Europe. This paper explores the variation of (1) acceptance issues across Europe, and (2) patterns of strategic and local planning in affecting WE acceptance. We conducted an expert survey among the members of the COST Action ‘Renewable Energy and Landscape Quality’ and the association Wind Energy Europe. We found that acceptance issues – as perceived by the experts – across different regions in Europe share certain similarities, such as concerns about landscape impacts. The priority-levels of acceptance issues are specific to each region and link to the planning quality in that context. Planners’ and decision-makers’ increased awareness about the diversity of acceptance issues would allow them to design more appropriate strategic and local planning processes.

This article aims to explore differences in motivation for and actual use of allotment gardens. Results from questionnaire surveys and semistructured interviews in two Norwegian and one Dutch garden show that growing vegetables and consuming the harvest is a fundamental part of gardening. The same is true for the social element—meeting and talking to other gardeners, and feeling as part of a community. Although gardeners with different socioeconomic backgrounds experience gardening to some extent similarly, access to an allotment seems more important for gardeners with disadvantaged personal backgrounds: both their diets and their social networks rely more on, and benefit more from, their allotments. This underlines the importance of providing easy access to gardening opportunities for all urban residents, and disadvantaged groups in particular. Public officers and policy makers should consider this when deciding upon new gardening sites or public investments in urban food gardens.
