According to a governmental decision, all (re)constructions in Dutch cities starting by 2020 have to be climate resilient. Part of this climate resilience is also adaptation to (extreme) heat. Although urban heat, its causes, consequences, and potential adaptation measures, have been extensively studied by scientists all over the world, the understanding of this problem among practitioners is still limited. Local governments are struggling with defining the urgency and finding the right arguments for adaptation to this aspect of climate change. Also questions asked by municipality officers often differ from those asked (and answered) by scientists. How do you define “heat stress”? What are the best adaptation measures for our city? How do we know we have reached “heat resilience”? Or; Shall we just do what they do in Italy?Project Heat Resilient Cities is a cooperation of two research institutes, 13 municipalities, and a water authority in Netherlands. The aim of this project is to bring the current knowledge of urban heat adaptation to practice and to fill in the research gabs. The research focuses on clear visualizations of problematic areas, applicable heat resilient measures in Dutch context, and design guidelines leading towards more heat resilient cities. In this presentation, we will present an overview of practical tools (maps, instruments measures, visualizations, guidelines) that cities could use put heat resilience into practice.
While the optimal mean annual temperature for people and nations is said to be between 13 °C and 18 °C, many people live productive lives in regions or countries that commonly exceed this temperature range. One such country is Australia. We carried out an Australia-wide online survey using a structured questionnaire to investigate what temperature people in Australia prefer, both in terms of the local climate and within their homes. More than half of the 1665 respondents (58%) lived in their preferred climatic zone with 60% of respondents preferring a warm climate. Those living in Australia's cool climate zones least preferred that climate. A large majority (83%) were able to reach a comfortable temperature at home with 85% using air-conditioning for cooling. The preferred temperature setting for the air-conditioning devices was 21.7 °C (SD: 2.6 °C). Higher temperature set-points were associated with age, heat tolerance and location. The frequency of air-conditioning use did not depend on the location but rather on a range of other socio-economic factors including having children in the household, the building type, heat stress and heat tolerance. We discuss the role of heat acclimatisation and impacts of increasing air-conditioning use on energy consumption.

Our unilateral diet has resulted in a deficiency of specific elements/components needed for well-functioning of the human body. Especially the element magnesium is low in our processed food and results in neuronal and muscular malfunctioning, problems in bone heath/strength, and increased chances of diabetes, depression and cardiovascular diseases. Furthermore, it has also been recognized that magnesium plays an important role in cognitive functioning (impairment and enhancement), especially for people suffering from neurodegenerative diseases (Parkinson disease, Alzheimer, etc). Recently, it has been reported that magnesium addition positively effects sleep and calmness (anti-stress). In order to increase the bioavailability of magnesium cations, organic acids such as citrate, glycerophosphate and glycinate are often used as counterions. However, the magnesium supplements that are currently on the market still suffer from low bio-availability and often do not enter the brain significantly.The preparation of dual/multiple ligands of magnesium in which the organic acid not only functions as a carrier but also has synergistically/complementary biological effects is widely unexplored and needs further development. As a result, there is a strong need for dual/multiple magnesium supplements that are non-toxic, stable, prepared via an economically and ecologically attractive route, resulting in high bioavailability of magnesium in vivo, preferably positively influencing cognition/concentration
Sinds januari 2015 werken we met lector Jeroen Kluck van de Hogeschool van Amsterdam in een onderzoeksproject 'De klimaatbestendige stad' [1] dat tot doel heeft te onderzoeken hoe gemeenten wijken en straten klimaatbestendig kunnen inrichten. De focus van het onderzoek ligt op het duiden van de urgentie van hittestress, op het ontwerpen van standaard klimaatbestendige situaties en op een afweging van kosten en baten (o.a. voordelen van vergroening). Onderzoekers en studenten van de Hanze en hogeschool Amsterdam hebben in dat kader gemeten aan de hitte tijdens de hete zomer van 2015. Ook zijn er testen uitgevoerd naar diverse groen blauwe voorzieningen in het stedelijk gebied naar het lange termijn functioneren ervan. In Hoogeveen is in workshops in detail gekeken naar oplossingen in diverse straten, in de laatste stap worden de kosten gedetailleerd en concrete inrichting van groen blauwe voorzieningen vergeleken met traditionele inrichting op diverse criteria.
In dit project doet Inholland samen met Nova College, MeerWaarde, Plangroep en de gemeente Haarlemmermeer verkennend participatief actieonderzoek naar een nieuwe preventieve werkwijze gericht op het bespreekbaar maken van schulden en stress onder jongeren tussen de 16 en 27 jaar. De schulden-en-stress-aanpak van MeerWaarde is niet eerder bij de doelgroep jongeren toegepast en vraagverlegenheid is niet eerder in dit verband onderzocht. Dit zijn vernieuwende aspecten in deze aanvraag. Vraagverlegenheid kan ertoe bijdragen dat jongeren niet over hun financiële problemen praten met anderen en schulden daardoor steeds hoger oplopen. Preventief werken wordt hierdoor bemoeilijkt. In dit project onderzoeken we op participatieve wijze hoe jongeren hun eigen vraagverlegenheid herkennen en erkennen als het gaat om het ervaren van geldstress, wat zij nodig hebben om hun hulpvraag aan anderen te articuleren en wat er nodig is om deze jongeren tijdig te ondersteunen. Dit levert nieuwe kennis op over de rol van vraagverlegenheid bij financiële problemen en biedt denkrichtingen voor nieuwe instrumenten en methodieken gericht op het bespreekbaar maken van geldstress bij jongeren. Met dit verkennend onderzoek bereiden we opschaling voor naar de regio’s Amsterdam en Rotterdam om die kennis, instrumenten en methodieken in een vervolgproject verder uit te werken.
