Norwegians in colonial Africa and Oceania had varying aspirations and adapted in different ways to changing social, political and geographical circumstances in foreign, colonial settings. They included Norwegian shipowners, captains, and diplomats; traders and whalers along the African coast and in Antarctica; large-scale plantation owners in Mozambique and Hawai'i; big business men in South Africa; jacks of all trades in the Solomon Islands; timber merchants on Zanzibar' coffee farmers in Kenya; and King Leopold's footmen in Congo. This collection reveals narratives of the colonial era that are often ignored or obscured by the national histories of former colonial powers. It charts the entrepreneurial routes chosen by various Norwegians and the places they ventured, while demonstrating the importance of recognizing the complicity of such "non-colonial colonials" for understanding the complexity of colonial history

This chapter takes into consideration two distinct processes utilised in CASI to develop new sets of sustainable research and innovation (R&I) agendas. The first process is based on European sustainable innovators' objectives, as gathered and analysed from more than 500 SI initiatives mapped in CASIPEDIA and led by the quadruple helix of SI stakeholders. The second draws on citizens' preferences, as identified in two rounds (citizens-experts-citizens) of participatory workshops carried out in 12 European countries. Some mismatches are identified and the chapter reveals that gaps exist between what is currently taking place in research and innovation, and what citizens wish for. Furthermore, the analysis demonstrates the potential of cross-disciplinary approaches to make cross-comparisons of data from multiple and diverse sources. ; Non peer reviewed

The Energy Modeling Forum 28 (EMF28) performed a large-scale model comparison exercise to illustrate different technology pathways for cutting European greenhouse gas emissions by 80% by 2050. Focusing on selected countries (France, Germany, Italy, Sweden, and UK), this paper first analyzes climate and energy policy objectives and debates in the respective countries. It then compares EMF28 model results to the short-term projections of the National Renewable Energy Action Plans (NREAPs) and the long-term transformation pathway given in the European Commission's "Energy Roadmap 2050". It concludes that there is sufficient agreement with the NREAPs and national policies to accept the model results as conceivable scenarios. The scenarios suggest that in the future a variety of different national energy mixes will continue to reflect the different resource bases and preferences of individual Member States. In order to ensure a cost-efficient transformation, it is important to improve coordination between Member State policies and those at the EU level.

Small-scale or artisanal fishery is a neglected sector in research on African development, despite the fact that fishery is a vital source of protein and income for a large number of people on the continent and an increasingly important source of revenue for national governments. In this volume research on artisanal fisheries has been pooled together. The contributors are mainly concerned with socio-economic conditions within the sector, but they also cover issues related to the management of fish resources and fishery development projects. Apart from several general themes the volume includes papers based on research from Mozambique, Zambia, Angola, Tanzania and West Africa. (DÜI-Hff)

Due to the heavy fuel oil (HFO) ban in Arctic maritime transport and new legislations restricting the sulphur content of fuel oils, new fuel oil types are continuously developed. However, the potential impacts of these new fuel oil types on marine ecosystems during accidental spills are largely unknown. In this study, we studied the toxicity of three marine fuel oils (two marine gas oils with low sulphur contents and a heavy fuel oil) in early life stages of cod (Gadus morhua). Embryos were exposed for 4 days to water-soluble fractions of fuel oils at concentrations ranging from 4.1 - 128.3 µg TPAH/L, followed by recovery in clean seawater until 17 days post fertilization. Exposure to all three fuel oils resulted in developmental toxicity, including severe morphological changes, deformations and cardiotoxicity. To assess underlying molecular mechanisms, we studied fuel oil-mediated activation of aryl hydrocarbon receptor (Ahr) gene battery and genes related to cardiovascular, angiogenesis and osteogenesis pathways. Overall, our results suggest comparable mechanisms of toxicity for the three fuel oils. All fuel oils caused concentration-dependant increases of cyp1a mRNA which paralleled ahrr, but not ahr1b transcript expression. On the angiogenesis and osteogenesis pathways, fuel oils produced concentration-specific transcriptional effects that were either increasing or decreasing, compared to control embryos. Based on the observed toxic responses, toxicity threshold values were estimated for individual endpoints to assess the most sensitive molecular and physiological effects, suggesting that unresolved petrogenic components may be significant contributors to the observed toxicity. ; publishedVersion

Sentinel plants, plants in exporting countries that are inspected at regular intervals for signs and symptoms of invertebrate pests and microbial pathogens, are a promising tool for detecting and identifying harmful organisms of woody plants prior to their introduction into importing countries. Monitoring of sentinel plants reveals crucial information for pest risk analyses and the development of mitigation measures. The establishment of sentinel plants requires the import and plantation of non-native plants, which may be affected by the laws, regulations and administrative procedures in the individual countries. To evaluate the feasibility of sentinel plants as a global approach, this study aimed to summarise regulations and administrative procedures that affect the establishment of sentinel plants using non-native plants in countries worldwide. Information about national regulations of import and planting of non-native plant species was collected through a questionnaire survey, conducted among national representatives to the International Plant Protection Convention. Over 40 countries responded. The results show that legislations and regulations should not be major obstacles for a global use of the sentinel plants approach. However, the few existing experiences show that it can be complicated in practice. Here we describe the current state of art of the procedures that should be adopted to establish sentinel plants and we propose a strategy to circumvent the shortcomings resulting from the lack of a specific regulation. ; SCOPUS: ar.j ; info:eu-repo/semantics/published
