With increase in awareness of the risks posed by climate change and increasingly severe weather events, attention has turned to the need for urgent action. While strategies to respond to flooding and drought are well-established, the effects - and effective response - to heat waves is much less understood. As heat waves become more frequent, longer-lasting and more intense, the Cool Towns project provides cities and municipalities with the knowledge and tools to become heat resilient. The first step to developing effective heat adaptation strategies is identifying which areas in the city experience the most heat stress and who are the residents most affected. This enables decision-makers to prioritise heat adaptation measures and develop a city-wide strategy.The Urban Heat Atlas is the result of four years of research. It contains a collection of heat related maps covering more than 40,000 hectares of urban areas in ten municipalities in England, Belgium, The Netherlands, and France. The maps demonstrate how to conduct a Thermal Comfort Assessment (TCA) systematically to identify heat vulnerabilities and cooling capacity in cities to enable decision-makers to set priorities for action. The comparative analyses of the collated maps also provide a first overview of the current heat resilience state of cities in North-Western Europe.
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.
Research Questions • What are the characteristics of vulnerable populations in The Hague? • What are their needs in order to adapt to heatwaves, and how do they cope? • What are existing sustainable solutions for protecting vulnerable populations? • How can the municipality of The Hague increase urban resilience with regards to heat?
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.
