Abstract [en]

Sustainable urban development has been widely recognized as requiring energy and transport efficient urban growth, while ecological issues are often not well integrated in sustainability assessments and Strategic Environmental Assessment (SEA). In order to achieve such integration, methods and tools based on Geographic Information Systems (GIS) and a Landscape Ecological Assessment (LEA) framework were developed and integrated in planning in four case studies in and around the city of Stockholm, Sweden. This involved the application of recently developed methods for impact prediction and for integration into the planning processes. The aim of the study was to compare the case studies concerning strengths and weaknesses of LEA and its GIS-based components. The methodology enabled identification of important structures in the landscape to support biodiversity, across administrative borders.  The GIS-based LEA facilitated discussions on consequences of alternatives for localisation of built-up areas, infrastructure and other development as well as management, and could thus contribute to a sustainable urban development with consideration of the landscape-level biodiversity values.

Abstract [en]

Humans have a profound impact on ecosystems, and land-use change constitutes a primary driving force in the loss of biodiversity. Habitat loss and fragmentation are key factors in this process by seriously impeding the habitat availability and movement of species, leading to a significant decrease in population viability. Landscape connectivity management able of crossing administrative and ecological spatial and temporal scales has been identified as one of the most important measures to counteract these negative impacts. The use of graph-theory and network-based landscape-ecological tools has become established as a promising way forward to address these issues. Despite urgent needs to adapt and implement such tools in planning, assessment and decision-making, surprisingly little attention has been paid to developing approaches for their effective practical application. This thesis presents the development of a toolbox with network-based, landscape-ecological methods and graph-theoretic indicators, which can be effectively implemented by practitioners within environmental assessment, physical planning and design, to analyze landscape connectivity. Recent advances in network analysis and landscape ecology are brought together and adapted for practical application, bridging the gap between science and practice. The use of participatory approaches was identified as key to successful development, and several workshops, meetings, interviews, as well as prototype testing of the developed software were conducted throughout the study. Input data and selection of species were based on the experience gained through seven real-world cases, commissioned by different governmental organizations within Stockholm County. The practitioners’ perspectives on effective practical application of the proposed toolbox were then assessed through an interview-study. The respondents anticipated improved communication with other actors in addition to being able to better assess critical ecological structures within the landscape. The toolbox was finally tested in a large-scale network analysis of impacts of the regional development plan (RUFS 2010), leading to important insights on the planning of connectivity in an urbanizing region.
