In the federal state Belgium, landscape research evolved from regional geographical monographs to more applied research that focuses upon the specific problems in each of the regions. In the highly urbanized Flanders region in the north, aspects of suburbanization and fragmentation are the most important. Landscape research involves geographers, historians, archaeologists, agronomists, foresters, ecologists and nature conservationists all dealing with specific goals and tasks. The integration is mainly achieved in spatial planning. In the Walloon region large areas are still rural and have a large forest cover, while urbanized zones are rather concentrated. Landscape research focuses here mainly upon the rural involving geographers, agronomists and planners. The natural and scenic aspects of the landscape dominate and the study of the historical development of the landscape is less pronounced. In Brussels Capital region little attention is given to landscape aspects, as social and typical urban problems dominate. Consequently, different landscape typologies are used in Belgium. [less ▲]

Ecological thresholds are defined as points or zones at which a rapid change occurs from one ecological condition to another. The existence of thresholds in species - habitat relationships has important implications for management, but the lack of concordance across studies and the wide range of methods used make generalizations difficult. We used two different statistical methods to test for the existence of thresholds for both individual species and the whole community, using three newt species as models. Based on a sample of 371 ponds, we found significant thresholds for both landscape configuration and composition. These were for the relationships between distance to forest and occurrence of Triturus alpestris and T. helveticus, and forest and crop cover and T. helveticus. Variability in the location of thresholds observed for the different species in this study caution against their use at the community level. Future studies should be based on the identification and assessment of thresholds for targeted species. Thresholds can be a useful concept from which tools may be developed to focus conservation effort for threatened species and their habitats. [less ▲]

This paper presents results of the last five years of landslide detection and landslide susceptibility mapping in the Central and Southern Tien Shan. Landslide inventories have been compiled for areas of major interest in the Kyrgyz Republic. For those areas, landslides were first mapped manually using KFA satellite images and aerial photographs. Recently, a landslide detection method has been developed in order to map landslides automatically. This method is based on a neural network scheme applied to detect particular slope failure features from remote sensing data. Multi-spectral and/or panchromatic ASTER and SPOT images as well as digital elevation models (DEMs) are used as inputs. This automatic method is designed to map medium-size mass movements (105-107 m3). This approach supplements the manual mapping of large slope failures and helps to complete the inventory of mass movements and related landslide susceptibility/hazard maps for large areas within the Tien Shan. Size-frequency analyses have been applied to the two existing regional landslide inventories. These size-frequency analyses revealed the incompleteness of the respective inventories (in the low-size domain) as well as regional and local differences due to natural and anthropogenic influences. To be able to perform reliable susceptibility and size-frequency analyses, the completed inventories need to be verified. At present, we perform local verification by manual mapping and control, but automatic verification methods are being developed. They will also allow us to determine the level of uncertainties. Ongoing research is focused on the propagation of uncertainties throughout the chain of processing. [less ▲]

The North tanganyika – Kivu rift zones are areas naturally prone to landsliding where triggering and environmental factors that favour the occurrence of mass movement concentrate. In many places landslide hazard is very high, and anthropogenic factors such as land use change and urban expansion increase the sensibility to slope instability. From seismic to rainfall-induced mass movements we review the current knowledge of the various slope precesses and associated hazards that are present in these equatorial environments. A particular attention is given to urban areas such as Bukavu and Bujumbura where lanslide threat is particularly acute. Research perspectives on landslide inventorying, monitoring, and susceptibility and hazard assesment are presented. [less ▲]
