- This study addresses and conceptualizes the possible dependence of ecosystem services on prevailing air and/or water flow processes and conditions, and particularly on the trajectories and associated spatial reach of these flows in carrying services from supply to demand areas in the landscape. The present conceptualization considers and accounts for such flow-dependence in terms of potential and actually realized service supply and demand, which may generally differ and must therefore be distinguished due to and accounting for the prevailing conditions of service carrier flows. We here concretize and quantify such flow-dependence for a specific landscape case (the Stockholm region, Sweden) and for two examples of regulating ecosystem services: local climate regulation and storm water regulation. For these service and landscape examples, we identify, quantify and map key areas of potential and realized service supply and demand, based for the former (potential) on prevailing relatively static types of landscape conditions (such as land-cover/use, soil type and demographics), and for the latter (realized) on relevant carrier air and water flows. These first-order quantification examples constitute first steps towards further development of generally needed such flow-dependence assessments for various types of ecosystem services in different landscapes over the world.

Accessibility of Water-Related Cultural Ecosystem Services through Public Transport-A Model for Planning Support in the Stockholm Region
- 2017

Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 9:3

Tidskriftsartikel (refereegranskat)abstract
- Planning for sustainable cities involves supporting compact, energy-efficient urban form as well as maintaining attractive and liveable urban landscapes. Attractive cities depend highly on services provided by ecosystems, especially cultural ecosystem services (ES), which give direct benefits to urban citizens. Therefore, access to a diversity of urban functions and publicly available ES by walking and public transport should be considered when planning for sustainable cities. This could be facilitated by user-friendly planning support models. The aim of this study was to develop a GIS-based model for assessing accessibility to ES, more specifically, water-related cultural ecosystem services (WCES), via walking and public transport, with input from stakeholders. The model was applied to the Stockholm region in Sweden. Travel times and census data were used to derive measures and maps of accessibility to prioritised WCES in the region, today and in urbanisation scenarios for 2050. The results showed how access to WCES varied spatially within the region. The number of potential visitors to different WCES sites now and in the future urbanisation scenarios was estimated, and areas in need for future development of the public transport system as well as WCES were identified. The GIS-based accessibility model has potential to be used as planning support in urban planning.

Natural hazard susceptibility assessment for road planning using spatial multi-criteria analysis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Inadequate infrastructural networks can be detrimental to a society if transport between locations becomes hindered or delayed, especially due to natural hazards which are more difficult to control. Thus determining natural hazard susceptible areas and incorporating them in the initial planning process, may reduce infrastructural damages in the long run. The objective of this study was to evaluate the usefulness of expert judgements for assessing natural hazard susceptibility through a spatial multi-criteria analysis (SMCA) approach using hydrological, geological and land use factors. To utilize SMCA for decision support, an analytic hierarchy process (AHP) was adopted where expert judgements were evaluated individually and in an aggregated manner. The estimates of susceptible areas were then compared with the methods Weighted linear combination (WLC) using equal weights and Factor interaction method (FIM). Results showed that inundation received the highest percentage of susceptibility. Using expert judgement showed to perform almost same as Equal weighting where the difference (i.e. average) in susceptibility between the two for inundation was around 4%. Results also showed that downscaling could negatively affect the susceptibility assessment and be highly misleading. Susceptibility assessment through SMCA is useful for decision support in early road planning despite its limitation to selection and use of decision rule and criteria. A natural hazard SMCA could be used to indicate areas where more investigations need to be undertaken from a natural hazard point of view, and to identify areas thought to have higher susceptibility along existing roads where mitigation measures could be targeted after in-situ investigations.

First mile/last mile problems in smart and sustainable cities : A case study in Stockholm County
- 2022
-
Ingår i: The Journal of urban technology. - : Informa UK Limited. - 1063-0732 .- 1466-1853. ; 29:2, s. 115-137

Tidskriftsartikel (refereegranskat)abstract
- The first mile/last mile (FM/LM) problem in public transport refers to the spatial accessibility of public transport and is the most important factor determining whether an individual will choose public transport. The FM/LM problem in Stockholm County, Sweden, was evaluated using a Geographic Information System estimating distances to public transport for the years 2019 and 2035. Overall, the population in Stockholm County, have good access to public transport. However, access varies with abilities, with elderly having 50 percent and elderly impaired 15 percent of their area within walking distance to public transport compared with the average citizen. Planned developments can provide good access to public transport, with extensive improvements for the elderly. However, inadequate planning for population increase will likely decrease the perceived public transport accessibility. Apartments and commercial buildings in the study area have high access to public transport. Elderly people have good access within city and regional centers, while access could be improved in other areas. Inclusion of FM/LM in the planning support system used in Stockholm could help mitigate FM/LM problems and extend access to public transport to all people of different abilities. This is vital in creating sustainable mobility networks and achieving sustainable development in smart cities.

Planning support for reducing risks related to flooding in the Stockholm Region
- 2017
-
Konferensbidrag (refereegranskat)abstract
- The urbanization trend during the last decades have several environmental impacts, particularly associated with increasing runoff and flood hazard, and decreasing water quality. These topics have been investigated all around the world, but relatively little is known about the impacts of urban development at the early stage of the urban planning in cities. This project aims to develop planning support tools for addressing impacts of different urbanization patterns in alternative planning scenarios on surface water within the City of Stockholm, the capital of Sweden.With the help of urban planners at the municipality, alternative future urban scenarios will be created and assessed from a hydro-meteorological risk assessment perspective. The scenarios will include alternative development patterns for buildings, infrastructure and supply of several regulating and cultural ecosystem services. For the water-related risk assessment, a hydrological model will be set up and validated using available data for a selected catchment that is affected by the scenarios. This will then be used to assess the impacts of the scenarios on the hydrological response and its implications. In the end, the results are expected to contribute to identifying how localization and type of different ecosystem services in the urban planning can be employed as nature-based solutions for hydro-meteorological risk reduction and climate adaptation.

Integrating ecosystem services in the assessment of urban energy trajectories : A study of the Stockholm Region

Tidskriftsartikel (refereegranskat)abstract
- Urban development trajectories are changing towards compact, energy-efficient cities and renewable energy sources, and this will strongly affect ecosystem services (ES) that cities are dependent on but tend to disregard. Such ES can be provisioning, regulating and cultural ES, around which competition over land resources will increase with energy system shifts. Much of this can be foreseen to take place within urbanising regions that are simultaneously the living environment of a major part of the human population today. In order to inform critical urban policy decisions, tools for integrated assessment of urban energy and transport options and ecosystem services need to be developed. For this purpose, a case study of the Stockholm region was conducted, analysing three scenarios for the future urbanisation of the region, integrating a transport energy perspective and an ES perspective. The results showed that a dense but polycentric development pattern gives more opportunities for sustainable urban development, while the dense monocentric scenario has apparent drawbacks from an ES perspective. The methodology is compatible with a model integration platform for urban policy support and will thus enable integrated policy assessment of complex urban systems, with the goal of increasing their sustainability.

Tidskriftsartikel (refereegranskat)abstract
- Population increases and environmental degradation are challenges for urban sustainability. Planning support systems are available to assist local authorities in developing strategies toward sustainability and resilience of urban areas, but are not always used in practice. We adapted an open-source planning support system to the case of Stockholm County, Sweden, where there is a productive working relationship between researchers, city planners, and regional planners. We employed a collaborative approach in extending and updating the planning support system and analyzed the outcomes, in order to both improve the planning support system and to investigate the process of planner engagement in planning support system development. The approach involved systematic interactions with local planning authorities and e.g. additional data processing, integrating scientific knowledge, policy, and engagement by planners in the complex process of planning for sustainable urban development. This made the planning support system more user-friendly for local planners, facilitating adoption by planning authorities through overcoming common quality and acceptance barriers to the use of planning support system in practice. Involving planners in planning support system development thus increases (i) planning support system quality, producing relevant and up-to-date outputs, and (ii) acceptance for planning support system by regional planners. Further assessment is required to determine whether planners can operate the adapted planning support system unaided.
