Identifying Spatial Patterns and Ecosystem Service Delivery of Nature-Based Solutions
In: Environmental management: an international journal for decision makers, scientists, and environmental auditors, Band 69, Heft 4, S. 735-751
ISSN: 1432-1009
AbstractCompared to technical infrastructure, nature-based solutions, NBS, strive to work with nature and to move beyond business-as-usual practices in order to address societal challenges such as flood risks. This research aims to spatially identify possible NBS areas and evaluate the areas capacity to provide selected ecosystem services, ES, for the Lahn river landscape in Germany. The research follows the functional landscape approach using hydromorphological landscape units, HLU, based on specific biophysical spatial criteria, such as slope, to then identify locations which may be considered suitable for NBS. The current ES delivery of these possible NBS areas is then evaluated. The three ES assessed are carbon storage, nutrient retention and recreation. We then undertake a geospatial comparison analysis to show the spatial relationships and patterns that emerge in regards to the ES configuration of the distinct NBS apt areas. Results show the HLU method serves to delineate and identify areas where NBS may exist or be implemented. The data depicts a distinct spatial pattern for each possible NBS space and complementary ES delivery. This explorative method is a useful spatial approach that can support NBS implementation and serve to investigate the multiple benefits NBS provide. The use of ecosystem services to compare and understand NBS is a viable prospect that must, however, be cautiously, locally and scientifically approached. Noticeable limitations regarding ES assessment remain, as available methods are often insufficiently inclusive of natural ecosystem processes and functions. Further research should assess a broader spectrum of NBS and their delivery of ES.
Revealing Cultural Ecosystem Services through Instagram Images: The Potential of Social Media Volunteered Geographic Information for Urban Green Infrastructure Planning and Governance
With the prevalence of smartphones, new ways of engaging citizens and stakeholders in urban planning and governance are emerging. The technologies in smartphones allow citizens to act as sensors of their environment, producing and sharing rich spatial data useful for new types of collaborative governance set-ups. Data derived from Volunteered Geographic Information (VGI) can support accessible, transparent, democratic, inclusive, and locally-based governance situations of interest to planners, citizens, politicians, and scientists. However, there are still uncertainties about how to actually conduct this in practice. This study explores how social media VGI can be used to document spatial tendencies regarding citizens' uses and perceptions of urban nature with relevance for urban green space governance. Via the hashtag #sharingcph, created by the City of Copenhagen in 2014, VGI data consisting of geo-referenced images were collected from Instagram, categorised according to their content and analysed according to their spatial distribution patterns. The results show specific spatial distributions of the images and main hotspots. Many possibilities and much potential of using VGI for generating, sharing, visualising and communicating knowledge about citizens' spatial uses and preferences exist, but as a tool to support scientific and democratic interaction, VGI data is challenged by practical, technical and ethical concerns. More research is needed in order to better understand the usefulness and application of this rich data source to governance.

Incorporating Ecosystem Services into Water Resources Management—Tools, Policies, Promising Pathways
In: Environmental management: an international journal for decision makers, scientists, and environmental auditors, Band 69, Heft 4, S. 627-635
ISSN: 1432-1009
AbstractEcosystems provide a range of services, including water purification, erosion prevention, and flood risk mitigation, that are important to water resource managers. But as a sector, water resources management has been slow to incorporate ecosystem protection and restoration, for a variety of reasons, although related concepts such as nature-based solutions and green infrastructure are gaining traction. We explain some of the existing challenges to wider uptake of the ecosystem services concept in water resources management and introduce some promising avenues for research and practice, elaborated in more detail through 12 papers, spanning five continents and a variety of contexts, which make up a Special Issue on "Incorporating Ecosystem Services into Water Resources Management". Cross-cutting themes include (A) ecosystem services as a flexible concept to communicate with stakeholders; (B) participatory processes to involve stakeholders in research; (C) multiple values, and valuation methods, of water-related services; and (D) applications of decision-support tools. We conclude with a summary of research gaps and emphasize the importance of co-producing knowledge with decision makers and other stakeholders, in order to improve water resources management through the integration of ecosystem services.
Planung naturbasierter Lösungen in Flusslandschaften - Ein Handbuch für die Praxis
Deutschlands Flusslandschaften stehen vor großen Herausforderungen: Der Klimawandel erhöht das Risiko von Überschwemmungen und Wasserdefiziten, gleichzeitig greifen menschliche Baumaßnahmen wie Flussbegradigungen, Stauungen, Trockenlegungen von Feuchtgebieten oder der Bau von Deichen massiv in die komplexen Ökosysteme ein. Heutige Flusslandschaften sind den zunehmenden Extremereignissen, der Ressourcenknappheit und dem Biodiversitätsverlust kaum gewachsen. Naturbasierte Lösungen für Flusslandschaften bieten konkrete und langfristige Umgangsmöglichkeiten mit diesen gesellschaftlichen Herausforderungen, indem sie natürliche ökologische Funktionen fördern und nutzen. Die Nachwuchsforschergruppe PlanSmart stellt in diesem Handbuch die Grundlagen der Planung naturbasierter Lösungen in Flusslandschaften vor. Das Buch regt dazu an, über Umsetzungsmöglichkeiten für naturbasierte Lösungen nachzudenken, und kann als Leitfaden für die Planung und Realisierung dieser Lösungen dienen. Es gibt Auskunft über die einzelnen Planungsschritte und enthält praktische Methodensteckbriefe für eine bessere Umsetzung der einzelnen Schritte.
