    This article examines the origins of the natural-wine movement in Germany—the first of its kind in Europe—by exploring the crucial technological and social developments which prompted the use of derided “artificial” winemaking techniques. The forgotten social reformer Ludwig Gall, once known to as the “savoir of the small vintner,” helped to relieve the unreliable dependency of winegrowers on nature by perfecting a deacidification technique which allowed for pleasant wines in any vintage.

    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.

    Multifunctional land use has become a widely supported pathway for Europe's countryside. Brussels and the national governments stimulate farmers to integrate primary production with non-agricultural practices from which they can also benefit. In favour of this development different stakeholders are encouraged to collaborate to produce the so-called farmer-managed public goods. This paper explores critical success factors for the production and maintenance of these public goods.

    In this paper we evaluate the potential of ENVISAT–Medium Resolution Imaging Spectrometer (MERIS) fused images for land-cover mapping and vegetation status assessment in heterogeneous landscapes. A series of MERIS fused images (15 spectral bands; 25 m pixel size) is created using the linear mixing model and a Landsat Thematic Mapper (TM) image acquired over the Netherlands. First, the fused images are classified to produce a map of the eight main land-cover types of the Netherlands. Subsequently, the maps are validated using the Dutch land-cover/land-use database as a reference.

    Attitude surveys among affected groups are established tools for integrating actors into decision-making concerning wildlife management. However, the complexity of attitudes and the fact that general attitudes toward wildlife may differ from those toward specific management measures reveal the risk of misinterpreting the data obtained. This article explores these problems based on a quantitative survey of hunters and landowners living close to the Bavarian Forest National Park, Germany.

    Although developments in remote sensing have greatly improved land cover mapping, the mixed pixel problem has not yet been fully addressed. Soft classification techniques have been introduced to address the problem, but they do not show the spatial location of the class proportions in a pixel. Subpixel mapping has been introduced to address the drawbacks of soft classifications. In this work, the feedforward backpropagating neural network (FFBPNN) was used for subpixel mapping.

    Object-based image analysis (OBIA) is a widely used method for knowledge-based interpretation of very high resolution imagery. It relies on expert knowledge to classify the desired classes from the imagery at hand. The definition of classes is subjective, usually project-specific and not shared with the community. Ontologies as a form of knowledge representation technique are acknowledged as solution to establish and document class definitions independently of an OBIA framework. However, ontologies have not yet been strongly integrated in this image analysis framework.

    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.

    This article aims at testing whether the ecosystem services framework helps in understanding the link between local management and biodiversity conservation. Tourism was analysed in Camargue (France), a wetland area of high biodiversity value, via semi-structured interviews with local stakeholders. Three types of stakeholders were interviewed: protected area managers, livestock farmers and public institutions. This was done to examine whether they manage the land to enable tourism and/or maintain or restore the ecological state of ecosystems.
