Sustainability analysis of the CITYLAB solutions
The objective of the CITYLAB project is to develop knowledge and solutions that result in roll-out, upscaling and further uptake of cost effective strategies, measures and tools for emission free city logistics. CITYLAB includes a set of Living Laboratories where promising logistic concepts are implemented related to emissions free city logistics. The objective of this report is to assess the impact that would occur when the CITYLAB implementations would be scaled up. The main challenge that has to be overcome is the difference in type, availability and detail of data from different CITYLAB implementations. This assessment of the impacts of upscaling is done by integrating all stakeholdersâ opinions in the evaluation process and taking into account the costs and benefits for society as well as the financial viability for industry partners
Does the edge effect impact on the measure of spatial accessibility to healthcare providers?
Impact and process assessment of the seven CITYLAB implementations
CITYLAB focuses on four axes that call for improvement and intervention:
â˘Highly fragmented last-mile deliveries in city centres
â˘Inefficient deliveries to large freight attractors and public administrations
â˘Urban waste, return trips and recycling
â˘Logistics sprawl
Within these axes, the project supports seven implementations that are being tested, evaluated and rolled out. An implementation is defined as the process of preparing, testing and putting into practice a new service or a new way of operating or organising logistics activities.
The objective of this report is to present an assessment of the effects and consequences of the implementations as they are conducted. For each case, we summarise the process leading to the application of a specific technical and managerial solution, and present the outcomes.
For each implementation, we present
â˘Problem and aim
â˘Description of the solution
â˘Implementation process
â˘Effects and consequences
â˘Challenges ahead
â˘Lessons and generalisation of results
This deliverable provides a complete picture of the evolvement of the implementations during the CITYLAB project and final versions of the process and impact assessment
Assessing urban system vulnerabilities to flooding to improve resilience and adaptation in spatial planning
Fluvial, pluvial and coastal flooding are the most frequent and costly natural hazard. Cities are social hubs and life in cities is reliant on a number of services and functions such as housing, healthcare, education and other key daily facilities. Urban flooding can cause significant disruption to these services and wider impacts on the population. These impacts may be short or long with a variably spatial scale: urban systems are spatially distributed and the nature of this can have significant effects on flood impacts. From an urban-planning perspective, measuring this disruption and its consequences is fundamental in order to develop more resilient cities. Whereas the assessment of physical vulnerabilities and direct damages is commonly addressed, new methodologies for assessing the systemic vulnerability and indirect damages at the urban scale are required. The proposed systemic approach recognizes the city as a collection of sub-systems or functional units (such as neighborhoods and suburbs), interconnected through the road network, providing key daily services to inhabitants (e.g., healthcare facilities, schools, food shops, leisure and cultural services). Each city is part of broader systemsâwhich may or may not match administrative boundariesâand, as such, needs to be connected to its wider surroundings in a multi-scalar perspective. The systemic analysis, herein limited to residential households, is based on network-accessibility measures and evaluates the presence, the distribution among urban units and the redundancy of key daily services. Trying to spatially sketch the existence of systemic interdependences between neighborhoods, suburbs and municipalities, the proposed method highlights how urban systemic vulnerability spreads beyond the flooded areas. The aim is to understand which planning patterns and existing mixed-use developments are more flood resilient, thereby informing future urban development and regeneration projects. The methodology has been developed based on GIS and applied to an Italian municipality (Noale) in the metropolitan area of Venice, NE Italy
Ethnographic understandings of ethnically diverse neighbourhoods to inform urban design practice
The aim of this paper is to inform urban design practice through deeper
understanding and analysis of the social dynamics of public outdoor
space in ethnically diverse neighbourhoods. We hypothesise that
findings from ethnographic research can provide a resource that
improves cultural literacy and supports social justice in professional
practice. The primary method is a meta-synthesis literature review of 24
ethnographic research papers, all of which explore some dimensions of
public open space use and values in UK urban contexts characterised by
ethnic and racial diversity. We summarise thematic understandings and
significance of neighbourhood places of shared activity, parks, spaces of
passing-by and of retreat. We evaluate the implications for intercultural
social dynamics, exploring the spatial and temporal dimensions of
conviviality and racism in public open space. We then argue that it is
possible to develop principles for urban design practice informed by this
work, and propose four for discussion: maximising straightforward
participation, legitimising diversity of activity, designing in micro-retreats
of nearby quietness and addressing structural inequalities of open space
provision. We conclude that ethnographic research can provide detailed
insights into the use of the public realm and also inform a more nuanced
understanding of outdoor sociality relevant for an increasingly diverse
society. The challenge is two-fold: for ethnographers to become less
cautious in engaging with decisions and priorities regarding how cities
change, and for urban designers to explicitly embed informed
understandings of difference into their broad desire for inclusive public space
An argument against the focus on Community Resilience in Public Health
Background - It has been suggested that Public Health professionals focus on community resilience in tackling chronic problems, such as poverty and deprivation; is this approach useful?
Discussion - Resilience is always i) of something ii) to something iii) to an endpoint, as in i) a rubber ball, ii) to a blunt force, iii) to its original shape. âCommunity resilienceâ might be: of a neighbourhood, to a flu pandemic, with the endpoint, to return to normality. In these two examples, the endpoint is as-you-were. This is unsuitable for some examples of resilience. A child that is resilient to an abusive upbringing has an endpoint of living a happy life despite that upbringing: this is an as-you-should-be endpoint. Similarly, a chronically deprived community cannot have the endpoint of returning to chronic deprivation: so what is its endpoint? Roughly, it is an as-you-should-be endpoint: to provide an environment for
inhabitants to live well. Thus resilient communities will be those that do this in the face of challenges. How can they be identified?
One method uses statistical outliers, neighbourhoods that do better than would be expected on a range of outcomes given a range of stressors. This method tells us that a neighbourhood is resilient but not why it is. In response, a number of researchers have attributed characteristics to resilient communities; however, these generally fail to distinguish characteristics of a good community from those of a resilient one. Making this distinction is difficult and we have not seen it successfully done; more importantly, it is arguably unnecessary.
There already exist approaches in Public Health to assessing and developing communities faced with chronic problems, typically tied to notions such as Social Capital. Communityresilience to chronic problems, if it makes sense at all, is likely to be a property that emerges from the various assets in a community such as human capital, built capital and natural capital.
Summary - Public Health professionals working with deprived neighbourhoods would be better to focus on what neighbourhoods have or could develop as social capital for living well, rather than on the vague and tangential notion of community resilience.</p
Effects of residence and race on burden of travel for care: cross sectional analysis of the 2001 US National Household Travel Survey
BACKGROUND: Travel burden is a key element in conceptualizing geographic access to health care. Prior research has shown that both rural and minority populations bear disproportionate travel burdens. However, many studies are limited to specific types of patient or specific locales. The purpose of our study was to quantify geographic and race-based differences in distance traveled and time spent in travel for medical/dental care using representative national data. METHODS: Data were drawn from 2001 National Household Travel Survey (NHTS), a nationally representative, cross-sectional household survey conducted by the US Department of Transportation. Participants recorded all travel on a designated day; the overall response rate was 41%. Analyses were restricted to households reporting at least one trip for medical and/or dental care; 3,914 trips made by 2,432 households. Dependent variables in the analysis were road miles traveled, minutes spent traveling, and high travel burden, defined as more than 30 miles or 30 minutes per trip. Independent variables of interest were rural residence and race. Characteristics of the individual, the trip, and the community were controlled in multivariate analyses. RESULTS: The average trip for care in the US in 2001 entailed 10.2 road miles (16.4 kilometers) and 22.0 minutes of travel. Rural residents traveled further than urban residents in unadjusted analysis (17.5 versus 8.3 miles; 28.2 versus 13.4 km). Rural trips took 31.4% longer than urban trips (27.2 versus 20.7 minutes). Distance traveled did not vary by race. African Americans spent more time in travel than whites (29.1 versus 20.6 minutes); other minorities did not differ. In adjusted analyses, rural residence (odds ratio, OR, 2.67, 95% confidence interval, CI 1.39 5.1.5) was associated with a trip of 30 road miles or more; rural residence (OR, 1.80, CI 1.09 2.99) and African American race/ethnicity (OR 3.04. 95% CI 2.0 4.62) were associated with a trip lasting 30 minutes or longer. CONCLUSION: Rural residents and African Americans experience higher travel burdens than urban residents or whites when seeking medical/dental care
