Practical application of spatial ecosystem service models to aid decision support

Highlights • A structured protocol for adapting a spatial ecosystem service model to local contexts is proposed.• Decision context, the final users and uses of maps should drive the way the spatial ecosystem service models are structured.• Simply increasing spatial resolution is not sufficient to increase legitimacy and the ultimate utility of maps.• The type and level of stakeholders’ involvement is a determinant of spatial model usefulness.

Environmental justice for the governance of aquatic environments

ABSTRACT Environmental justice sheds light on the distributive and procedural aspects of planning and decision-making. We examined the challenges arising from the perspective of environmental justice on multi-level and participatory environmental governance by exploring the governance of aquatic environments in the Helsinki Metropolitan Area. We found three main challenges and potential responses to them. First, even though most of Helsinki’s shoreline is free and/or accessible by road and accordingly used actively by people for recreational purposes, many parts of the shoreline are perceived as inaccessible, reflecting a need to combine factual and perceived accessibility of aquatic environments in detail during the planning processes and to discuss reasons for possible discrepancies between these two. Second, there was a remarkable seasonal variation in the use of aquatic environments, so more attention should be paid to social-demographic factors explaining the distribution of the use of urban nature. Third, it seems to be difficult to capture the variety of perceptions of people and to integrate them into planning and decision-making processes even on a local scale, and this challenge is likely even more pronounced on higher levels of planning and governance. Thus, better integration of regional and local-scale planning procedures should be encouraged. Building on these observations, we conclude that integration of procedural and distributive environmental justice into the practices of the governance of aquatic environments could remarkably decrease unwanted trade-offs and potential conflicts in their use and management.

Balancing Urban Green Space and Residential Infill Development: A Spatial Multi-Criteria Approach Based on Practitioner Engagement

The objectives in consolidating the urban form and preserving green spaces are often in conflict in growing cities. The usability of spatial multi-criteria decision analysis (SMCDA) was tested as a tool for integrating residential infill development and urban green spaces in the City of Jarvenpaa, Finland. In collaboration with local practitioners, this study focused on the benefits and challenges of SMCDA. The results were based on two workshops with the practitioners along with comprehensive GIS analyses based on a wide range of available data. The practitioners saw SMCDA as a useful method to bring together a variety of factors related to infill development. They highlighted the importance of the method’s transparency, emphasising the comprehensive explanation of each step of the method. Better understanding of the impact of individual criteria weightings on the results was mentioned as one of the key future developments of the method.
