    This study is a contribution to a model intercomparison experiment initiated during a workshop at the 2013 IAHS conference in Göteborg, Sweden. We present discharge simulations with the conceptual precipitation–runoff model COSERO in 11 basins located under different climates in Europe, Africa and Australia. All of the basins exhibit some form of non-stationary conditions, due, for example, to warming, droughts or land-cover change.

    The robustness of the physically-based, semi-distributed hydrological model ECOMAG with respect to changing (climatic or land-use) conditions was evaluated for two basins, considered within the modelling workshop held in the frame of the 2013 IAHS conference in Göteborg, Sweden. The first basin, the Garonne River basin, France, is characterized mostly by changes in climatic conditions, while the second, Obyån Creek, Sweden, was exposed to drastic land cover change due to deforestation.

    Testing hydrological models under changing conditions is essential to evaluate their ability to cope with changing catchments and their suitability for impact studies. With this perspective in mind, a workshop dedicated to this issue was held at the 2013 General Assembly of the International Association of Hydrological Sciences (IAHS) in Göteborg, Sweden, in July 2013, during which the results of a common testing experiment were presented.

    The Dividalen (Sami: Dieváidvuovdi) valley in Troms county, North Norway, is well known for its old-growth pine forest, a biodiversity hotspot for dead wood-inhabiting fungi and lichens. The majority of the valley is protected within the Upper Dividalen Landscape Conservation Area and National Park. A general conception is that until the mid-nineteenth century when agriculture and forestry entered the valley, the landscape was entirely untouched by man and only used as a pathway for Sami and their reindeer herds on their annual migrations between Sweden and the Norwegian coast.

    Carl Malmström's historical forest maps of the province of Halland, in south-western Sweden, were published over 70 years ago, but are still important to science and conservation. They show the transformation of a seventeenth century landscape of temperate broadleaves to a landscape dominated by open land and heather (Calluna vulgaris) in the nineteenth century, and to a landscape of coniferous forest plantations in the twentieth century. This article summarizes and reviews the original research, first published in Swedish in 1939.

    Artificial neural networks (ANN) are nonlinear models widely investigated in hydrology due to their properties of universal approximation and parsimony. Their performance during the training phase is very good, and their ability to generalize can be improved by using regularization methods such as early stopping and cross-validation. In our research, two kinds of generic models are implemented: the feed-forward model and the recurrent model.

    Sweden is undergoing an extensive transformation from single species management towards ecosystem-based management. This study analyses the implementation of the new moose management system, focusing on the newly formed partnerships at ecosystem level (the moose management areas) and their potential to ease conflicts between participants and develop into sustainable collaborations that enable ecosystem-based management.

    Forest use in Sweden may be seen as constituting an essentially conflicted area, in which a number of actors position themselves. Based on a review of policy documents, this study reviews discourses on forest amongst major organisational actors between 2001 and 2011, with the aim of discussing the ways in which discourse may have changed following increasing criticism of the previously dominating production paradigm during the period. The study also discusses the ways in which forest discourses at present may also exclude areas that are relevant to forest planning.
