The model framework MULBO (Multicriteria Landscape Assessment and Optimisation) is a spatially explicit decision support method on the basis of risk evaluations for landscape functions. Its principal purpose is the establishment of optimal land use patterns as scenarios, which are balanced compromises between conflicting goals for the reduction of assessed risks. A user manual for MULBO has been developed which contains the individual assessment tools, the landscape optimisation method LNOPT 2.0, a multiplicity of applications, as well as information about data and techniques. After an introductory discussion of fundamentals for spatial decision-making, the methods and contents of MULBO are presented and discussed on basis of applications in a rural area in the southern part of Saxony-Anhalt (Germany). An applied project converts the scenario results recently into possible practices.

The field site network (FSN) plays a central role in conducting joint research within all Assessing Large-scale Risks for biodiversity with tested Methods (ALARM) modules and provides a mechanism for integrating research on different topics in ALARM on the same site for measuring multiple impacts on biodiversity. The network covers most European climates and biogeographic regions, from Mediterranean through central European and boreal to subarctic. The project links databases with the European-wide field site network FSN, including geographic information system (GIS)-based information to characterise the test location for ALARM researchers for joint on-site research. Maps are provided in a standardised way and merged with other site-specific information. The application of GIS for these field sites and the information management promotes the use of the FSN for research and to disseminate the results. We conclude that ALARM FSN sites together with other research sites in Europe jointly could be used as a future backbone for research proposals.
