The present energy crisis and the awareness of the human impact on climate change have boosted the public debate on the accelerated deployment of renewable energy sources. The objective of this research project is to analyse and assess the landscape capacity and social attitudes towards wind energy parks in Belgium, especially in non-urban and non-industrial sites. This research project starts from the observation that a sustainable production of energy, relying on renewable resources, should go hand in hand with a sustainable societal support for the use of these renewable sources. Experiences from neighbouring countries showed that the societal support depends of the regional landscape capacity and the social attitudes towards wind energy parks. In this research project both quantitative and qualitative research techniques will be used to: (1) measure the landscape capacity in relation to the location of wind energy parks in Belgium, (2) to gain insight in the way attitudes towards wind energy parks are socially constructed and reproduced.

The characteristics of colored dissolved organic matter (CDOM) as well as the concentrations and stable isotope composition (d 13 C) of dissolved organic carbon (DOC) were characterized in several large rivers of Africa including the Congo, Niger, Zambezi, and Ogooué basins. We compared the spatial and temporal patterns of dissolved organic matter (DOM) quantity and quality along with various environmental gradients, including hydrology, river size, catchment vegetation, and connectivity to land. The optical proxies used include the absorption coefficient at 350 nm, the specific ultraviolet absorbance, and the spectral slope ratio (S R = 275–295-nm slope divided by 350–400-nm slope). Our results show that land cover plays a primary role in controlling both DOC concentration and optical properties of DOM in tropical freshwaters. A higher cover of dense forest in the catchment leads to a higher quantity of highly aromatic DOM in the river network, whereas an increasing savannah cover results in lower DOC concentrations and less absorptive DOM. In addition to land cover, the watershed morphology (expressed by the average slope) exerts a strong control on DOC and CDOM in tropical rivers. Our results also show that the percentage of C3 and C4 vegetation cover is not an accurate predictor for DOM and CDOM quality in rivers due to the importance of the spatial distribution of land cover within the drainage network. The comparison of our results with previously published CDOM data in temperate and high-latitude rivers highlights that DOM in tropical freshwa-ters is generally more aromatic, and shows a higher capacity for absorbing sunlight irradiance.

In Europe, agri-environment schemes (AES) are designed to give credit to environmental issues in agricultural practices. Among the different Walloon AES, some are dedicated to enhance and preserve biodiversity linked to the agroecosystems. This study wishes to explore, at a landscape scale, how do different AES perform regarding butterflies and syrphidae diversity. Data collection occurred in five categories of ecological infrastructures (EI): four types of agri-environmental schemes (grassy strips, wildflower strips, bird-feeding margins, species-rich meadows) and cereal crops. Five replicates were selected for each category. Syrphidae were collected in water traps once per month, from May to July. Butterflies were monitored along transects from May to Augustus. Plant species were identified in every plot, within a 1-m radius around the traps and along a transect through every plot. Preliminary results show that abundance and species diversity of butterflies is significantly higher in parcels with floral resources. Moreover, hosts plants for larvae and foraging plants for adults are significantly more present in two types of AES: the wildflower strips and the species-rich meadows. Regarding the identified plant species, categories are divided in three groups (crops apart): bird-feeding margins; species-rich meadows and grassy strips; wildflower strips (Fig.1). Concerning hoverflies, a significantly higher abundance is observed in the wildflower strips compared to the crops in June (p= 0.008). Other abundance values in May and July show no difference. These results suggest that wildflower strips are performing infrastructures for biodiversity conservation in agroecosystems. As the presence of floral resources seem to be an important factor for the presence of foraging of adults, attention should be paid to the provisioning of food resources for the larval stages, especially butterflies, at a landscape scale in order to assure a sustainable approach in biodiversity support.

The aim of the seminar is to present the Landscape Laboratory and to explore the different directions of thoughts towards which Roland Gustavsson’s work is pointing, by presenting experiences directly inspired by Alnarp, and other examples exploring similar issues in different contexts. The Landscape Laboratory is a place for multidisciplinary research and experimentation in a 1 to 1 scale. The approach is based on theoretical foundations that share a belief in the essential character of ‘embodied knowledge’, where practical and theoretical knowledge is constructed through dialogue. Starting from the presentation of concrete examples (in Alnarp and elsewhere), the seminar will look at the specificity of the research methodology developed by Roland Gustavsson, and study its applicability to other sites, such as for example the Meuse valley around Liège.
