Whose health in whose city? A systems thinking approach to support and evaluate plans, policies, and strategies for lasting urban health.

An increasing interest has been present in scientific literature and policy-making for the links between urban environments and health, as also learnt from the COVID-19 pandemic. Collaboration between urban planning and public health is therefore critical for enhancing the capabilities of a city to promote the well-being of its people. But what leverage potential for urban health can be found in existing plans, policies, and strategies that address urban health? Starting from the relationship between urban systems and health issues, the purpose of this contribution is to broaden the systemic knowledge of urban systems and health so as to try to figure out the impact potential of local urban governance on public health. Considering the systemic nature of health issues, as defined by the World Health Organisation, this is done through a Systems Thinking epistemological approach. Urban health proposals are studied and assessed in four European cities (Copenhagen, London, Berlin, and Vienna). Current criticalities are found, starting from the guiding goal of such proposals, yet a systemic approach is suggested aimed at supporting and evaluating lasting and healthy urban planning and management strategies

Supporting a circular economy strategy in South Tyrol, Italy: Integrated life-cycle energy and greenhouse gas analysis

The research project “Strategy for Circular Economy in the Autonomous Province of Bolzano” aimed at providing the Province of Bolzano (South Tyrol, northern Italy), with materials and tools to support the design of an integrated regional strategy for Circular Economy (CE). The project focused on synergies between the bioeconomy and the built environment, due to their local relevance and to their significant potential in the transition to a CE. In particular, the project illustrated the application of a set of analytical tools to evaluate and support the design, development and implementation of CE strategies. In 2015, forestry and agriculture sectors were associated with about 5% of the gross domestic product (GDP) in the Province, compared to 2% in Italy (ASTAT, 2021). The project analyses illustrate how the integration of different tools can be used to estimate the potential benefits and impacts of the exchange and valorisation of co-products and waste from agriculture and forestry activities, in construction materials and products. The analyses included: (1) a spatial analysis using geographic information systems (GIS); (2) a simplified material flow analysis (MFA) of the residential building stock; and (3) a streamlined life-cycle energy and greenhouse gas (GHG) analysis comparing wood fibre and expanded polystyrene (EPS) insulation. The spatial analysis consisted of an estimate and mapping of potentially available biomass from forestry and agricultural activities, using land-use data – namely the area of agricultural land for three types of crops (feed crops, fruit, and vineyards) – and literature-based coefficients on generation of wood-based biomass from these three types of crops. The MFA estimated annual material inputs and outputs of the residential building stock in the Province, providing a simplified characterization of raw material construction requirements and demolition waste. The evaluation considered literature-based coefficients on: renovation and demolition rates, generation of waste per renovated/demolished surface, material separation factors and composition of waste. Different scenarios were established to account for variability in the intensity of construction and demolition activities. Lastly, a streamline life-cycle energy and GHG analysis comparing wood fibre and expanded polystyrene (EPS) insulation was performed. The analysis considered a cradle-to-gate perspective and, as functional unit, the insulation of a 1 m2 surface with a thermal resistance of 1 m2 K/W, across a service life of 50 years, and estimated the potential primary non-renewable energy (NRE) requirements and GHG emissions, with a 100-year time horizon. The analysis of potentially available biomass in the Province estimated and mapped an annual generation of (i) about 88 000 tons of residual biomass from agricultural activities, and (ii) about 465 000 m3 of residual biomass from forestry activities/management. Regarding construction and demolition waste, 7 000 - 12 000 tons of wood waste were estimated, which could have valuable potential if properly separated from mineral components and recovered. The LC analysis showed a potential reduction of 40-60% in NRE and 15-40% in GHG emissions, depending on the electricity mix considered (national or regional), if locally produced wood fibre insulation was used to replace EPS. It is important to highlight that the analyses were strongly limited by data unavailability; however, they had an illustrative and awareness-raising nature and complemented a participatory approach involving a range of local stakeholders across relevant economic sectors. Moreover, the project supported the creation of a regional competence centre for circular economy, which shall further develop the knowledge and tools to enable the transition to a CE in the Province, including the creation of an online trading platform for exchange of resources.

OS-WALK-EU: An open-source tool to assess health-promoting residential walkability of European city structures

Introduction This paper introduces OS-WALK-EU, a new open-source walkability assessment tool developed specifically for urban neighbourhoods and using open-source spatial data. A free and open-source tool, OS-WALK-EU is accessible to the general public. It uses open data available worldwide and free online services to compute accessibility, while at the same time allowing users to integrate local datasets if available. Based on a review of existing measurement concepts, the paper adopts dimensions of walkability that were tested in European city environments and explains their conceptualization for software development. We invite the research community to collaboratively test, adopt and use the tool as part of the increasing need to monitor walkability as part of health-promoting urban development. Methods Tool development is based on spatial analysis methods to compute indicators for five dimensions of walkability: residential density, weighted proximities to amenities, pedestrian radius of activity, share of green and blue infrastructure, and slope. Sample uses in the cities of Dublin, Düsseldorf and Lisbon test the validity of input data and results, including scenarios for target groups like older people. Results Overall, application of the tool in Dublin, Düsseldorf and Lisbon shows conclusive results that conform to local knowledge. Shortcomings can be attributed to deficiencies in open source input data. Local administrative data, if available, is suitable to improve results. Conclusions OS-WALK-EU is the first software tool that allows free and open walkability assessments with pedestrian routing capacities for ‘proximity to facilities’ calculations. Large scale implementation for 33 German city regions in an online application shows the value of comparative assessments of walkable neighbourhoods between urban and suburban neighbourhoods. Such assessments are important to monitor progress in a mobility transition towards improved walkability and public health

Regional Infrastructure Planning Support Methodology for Public and Private Electrified Transport: A Mountain Case Study

The European Union has seen a strong growth of electric passenger vehicles over the last decade. The steady increase in the number of electric vehicles requires a thorough examination of the current infrastructure and their future development, which are critical to the continuous market growth of this technology. The underdeveloped charging infrastructure is identified as one of the main barriers, next to the purchase price of electric vehicles. Thus, the infrastructure (supply side) and the vehicles (demand side) must coevolve and consider not only the quantitative balance between EVs and charging stations but the interlinkages with social, technical, and economic criteria for the overall system development. In this context, the methods presented in this paper address regional specificities when developing an integrated network of charging infrastructure for private and public passengers transport in an alpine region. The results of the application of the methodology to a mountainous area present the potential for replicability and highlight the importance of considering regional characteristics and of stakeholder involvement
