The phenomena of urbanization and climate change interact with the growing number of older people living in cities. One of the effects of climate change is an increased riverine flooding hazard, and when floods occur this has a severe impact on human lives and comes with vast economic losses. Flood resilience management procedures should be supported by a combination of complex social and environmental vulnerability assessments. Therefore, new methodologies and tools should be developed for this purpose. One way to achieve such inclusive procedures is by incorporating a social vulnerability evaluation methodology for environmental and flood resilience assessment. These are illustrated for application in the Polish city of Wrocław. Socio-environmental vulnerability mapping, based on spatial analyses using the poverty risk index, data on the ageing population, as well as the distribution of the areas vulnerable to floods, was conducted with use of a location intelligence system combining Geographic Information System (GIS) and Business Intelligence (BI) tools. The new methodology allows for the identification of areas populated by social groups that are particularly vulnerable to the negative effects of flooding.

BackgroundIdentifying modifiable factors associated with well-being is of increased interest for public policy guidance. Developments in record linkage make it possible to identify what contributes to well-being from a myriad of factors. To this end, we link two large-scale data resources; the Geoscience and Health Cohort Consortium, a collection of geo-data, and the Netherlands Twin Register, which holds population-based well-being data.ObjectiveWe perform an Environment-Wide Association Study (EnWAS), where we examine 139 neighbourhood-level environmental exposures in relation to well-being.MethodsFirst, we performed a generalized estimation equation regression (N = 11,975) to test for the effects of environmental exposures on well-being. Second, to account for multicollinearity amongst exposures, we performed principal component regression. Finally, using a genetically informative design, we examined whether environmental exposure is driven by genetic predisposition for well-being.ResultsWe identified 21 environmental factors that were associated with well-being in the domains: housing stock, income, core neighbourhood characteristics, livability, and socioeconomic status. Of these associations, socioeconomic status and safety are indicated as the most important factors to explain differences in well-being. No evidence of gene-environment correlation was found.SignificanceThese observed associations, especially neighbourhood safety, could be informative for policy makers and provide public policy guidance to improve well-being. Our results show that linking databases is a fruitful exercise to identify determinants of mental health that would remain unknown by a more unilateral approach.
Het team van het Healthy Urban Living Lab heeft samen met veel studenten van de Hogeschool van Amsterdam een Health Impact Assessment (HIA) uitgevoerd op de plannen voor het Bajes Kwartier. Dat is een groene, gezonde, duurzameAmsterdamse stadswijk die wordt gebouwd op het terrein van de voormalige Bijlmerbajes, gelegen in Stadsdeel Oost nabij de Amstel. In deze nieuwe wijk komen ongeveer 1.350 koop- en huurwoningen, variërend van betaalbarestarterswoningen tot exclusieve huizen en zorgwoningen. De focus van de HIA lag op drie aspecten die an groot belang zijn voor de gezondheid van inwoners van Amsterdam: bewegen, gezonde voeding en ontmoeten. Daarmeesluit de HIA aan bij de grootste uitdagingen voor de gezondheid van de Amsterdammers, overgewicht en eenzaamheid. Een HIA is een kritische en systematische beschouwing van een project, met als doel de kansen voor gezondheid en onbedoelde aspecten (zoals gezondheidsrisico’s) in kaart te brengen. Om te onderzoeken hoe de ambitie ‘alle bewoners leven hier twee jaar langer en gezonder kan worden gerealiseerd, is het Behaviour Change Wheel van Susan Michie (2011) gebruikt als theoretisch kader. Dit wetenschappelijkonderbouwde gedragsveranderingsmodel wordt ingezet voor het systematisch ontwerpen en evalueren van interventies en voor beleid dat is gericht op gedragsverandering. Het wordt veelal toegepast in de gezondheidsbevordering. Daarbij spelen drie elementen de hoofdrol: Capabilities (fysieke en psychologische vaardigheden), Opportunities (aspecten in de fysieke of sociale leefomgeving) en Motivation (bewuste en onbewuste processen die tot gedrag leiden). Naast een scan van het masterplan voor het Bajes Kwartier – vanuit het oogpunt van gezondheid – is een doelgroepanalyse gemaakt door middelvan een vragenlijst die werd verspreid onder belangstellenden c.q. toekomstige bewoners, een groepsbijeenkomst en doelgroepenonderzoek door studenten. Er is ook een wetenschappelijke literatuurstudie verricht. Vanuit de volksgezondheid kent de gezonde leefomgeving een afwisseling van bebouwing met groen, aantrekkelijke, uitdagende en gevarieerde openbare ruimten die uitnodigen tot bewegen, spelen en sport, gezond eten, het ontmoeten vanbuurtgenoten, een breed voorzieningenaanbod (waaronder ook een openbare toiletten en een maximale bereikbaarheid en verkeersveiligheid met de fiets en het openbaar vervoer). Daarnaast is in de leefomgeving sociale steun en socialeveiligheid nodig. Het beschikbaar maken van een leefomgeving die deze elementen bevat, is op zich niet voldoende. Er zijn ook activiteiten en netwerkennodig die bevorderen dat deze wijkinfrastructuur daadwerkelijk wordt benut. Zowel uit de literatuur als uit het doelgroepenonderzoek kwam dit naar voren als een belangrijke sleutel tot het creëren van gezondheidswinst. De conclusies die volgen uit de resultaten van de HIA, resulteren in vijf basisaanbevelingen.1) Focus op de diverse groepen. Iedere bewoner heeft recht op een gezonde omgeving. De gezondheidswinst die te behalen valt is het grootst onder kwetsbare groepen zoals bewoners met een lage sociaal economische status, ouderen en kinderen. 2) Gezond gedrag vereist participatie van bewoners waarbij alle doelgroepen vertegenwoordigd zijn. 3) Verbind de hardware met de software, maak een koppeling tussen de inrichting van de fysieke en de sociale omgeving 4) Zet alle vormen en varianten van nudging in, het helpt bewoners een gezonde leefstijl aan te nemen. 5) Hanteer een integrale aanpak waarbij deverschillende verantwoordelijke stakeholders zoals ontwerpers, planologen, burgers, kennisinstellingen, private partijen (zoals startups), gemeentes, GGD’en, zorgverzekeraars en zorgverleners vanaf het begin in eenruimtelijk planproces samenwerken

Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.
Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
Over the last couple of years there is a growing interest in the role of the bicycle in Western urban transport systems as an alternative to car use. Cycling not only has positive environmental impacts, but also positive health effects through increased physical activity. From the observation of the Urban Intelligence team that cycling data and information was limited, we have started the development of cycleprint. Cycleprint stands for Cycle Policy Renewal and INnovation by means of tracking Technology with the objective to enable more customer friendly cycle policy.The initial objective of Cycleprint was to translate GPS data into policy relevant insights to enable customer friendly cycle policy. The online toolkit what Cycleprint has become, answers the questions about:-route choice-speeds-delays at intersections -intensities Because of the success of Cycleprint in the Netherlands the range of features is still under development. As a result of the development of Cycleprint the Dutch organized the fietstelweek. In addition to Cycleprint the Urban Intelligence team developed the cyclescan to explore the effects of cycle network enhancement. The project is developed in direct collaboration with the Provincie Noord-Brabant and Metropoolregio Eindhoven to fulfill the ambition to become cycling region of the Netherlands in 2020.
