    Throughout the Netherlands, land owners (or their lessees) use adjacent public or private land without any right. There is, however, no scientific empirical data on how often and where land is illegally used. On the basis of empirical case studies, this research has the following aims: make an estimate of how often illegal land use occurs in the Netherlands; which kind of land is illegally used; in what kind of spatial context it is illegally used; and for what purpose it is illegally used.

    Multi-criteria decision analysis (MCDA), also termed as multi-criteria assessment (MCA), is a powerful policy appraisal tool but as Stirling (2006) has suggested, it can be used both for opening up and closing down policy discourses. Our analysis of MCA in addressing a conflict between state forestry and indigenous Sámi reindeer herding in Upper Lapland, Finland, illustrates MCA's potential in promoting open discussion about policy alternatives and their consequences, and also its limitations in highly controversial policy processes.

    The abandonment of farmland has become a widespread phenomenon in post-socialist countries that have seen revolutionary changes in their economic systems. The phenomenon is notable in vineyard areas, where abandonment leads to the loss of the unique character of vineyard landscapes. This paper assesses the extent of vineyard abandonment in Slovakia and analyses the driving forces behind it. We used statistical and Corine Land Cover data to map the change in vineyard areas in Slovakia and analyse the pressure of underlying driving forces.

    At present, spatially very detailed data sets can be obtained about soil, landscape and crop variability. However, there is a need to select independent key properties to identify management classes needed for precise land management. In a previous study performed in the European loess belt, topsoil pH, apparent electrical conductivity (ECa) and elevation were identified as key properties. In this study we enlarged the number of soil properties by including gamma ray measurements and employed a similar methodology to a field in the sand belt of northern Europe.

    The effect of shallow water table fluctuations on the evaporation and CO₂ fluxes in a peatland is investigated. The fluxes of evaporation and net ecosystem exchange of carbon were measured from mid-spring to the end of summer in 2005 and 2006 and simulated independently with process models. The observed and modelled data were then compared along a gradient of water levels. Any variation along the gradient would imply an influence of the water table on the flux. It became evident that changes in the water table had no effect on the evaporation and CO₂ fluxes of the peatland.

    Coastal dune systems are particularly susceptible to destabilisation through recreational pressure and because of this, conflicts frequently arise between those who want to use the dunes for recreational purposes and those who wish to see these fragile ecosystems protected. In addition, a range of approaches to resolving this conflict are being used in different countries with differing levels of success. To study this conflict, an approach based on the Q-method was applied to three European Union Member States, i.e.

    The aim of this paper is to shed new light on urban common property systems. We deal with urban commons in relation to urban green-space management, referring to them as urban green commons. Applying a property-rights analytic perspective, we synthesize information on urban green commons from three case-study regions in Sweden, Germany, and South Africa, and elaborate on their role for biodiversity conservation in urban settings, with a focus on business sites. Cases cover both formally established types of urban green commons and bottom-up emerged community-managed habitats.

    The present study demonstrates remote sensing derived phenological and productivity indicators of ecosystem functional dynamism. The indices were derived from SPOT VEGETATION NDVI data on 1km spatial resolution across the pan-European continent using the Phenolo approach. The phenological and productivity indices explained 78% of the variance in the European ecosystem gradient measured by bio-climatic zones. Along this gradient climatic predictors could only explain 57% of the variance in the satellite metrics.

    In this paper is presented a methodological approach which integrates statistic modelling and 2-D cellular automata (CA) in order to describe tree species shifts responding to the climate changes foreseen for Italy in the 21st century. Five Italian tree species populations of Abies alba, Pinus sylvestris, Fagus sylvatica, Acer campestris and Quercus suber and their actual potential distributions (PDs) – represented by Importance Value (IV), have been considered.
