Het Knowledge Mile Park (KMP), momenteel de drukste verkeersader van Amsterdam, wordt de komende jaren uitgebreid vergroend. Op diverse locaties langs de KMP werd steekproefsgewijs hittemetingen uitgevoerd om hittestress op te sporen, verkoelingscapaciteit van het aanwezige groen te meten en het thermisch comfort van de KMP voor de gebruiker te inventariseren. Er werd volgens het Cool Towns Heat Stress Measurement Protocol (Spanjar e.a., 2020) hittemetingenuitgevoerd met mobiele weerstations, infraroodcamera’s en vragenlijsten. Uitgevoerd op twee opeenvolgende dagdelen tussen 17.00 tot 20.00 uur. Dit vond plaats op 21 en 22 augustus 2023 toen de luchttemperatuur 23-25 °C bereikte. De resultaten geven het hitteverloop van een milde warme zomerdag weer. Uit de enquête afgenomen onder KMP-gebruikers blijkt dat meer dan de helft van de respondenten op zowel het Weesperplein als het Wibautpark het als een beetje warm of neutraal ervaren. De meetresultaten komen overeen met Europees hitteonderzoek (Spanjar e.a., 2022) en laat zien dat op locaties in de zon zoals op het stenige Weesperplein en het grasveld, mensen tussen 17.00 en 18.30 uur te maken hebben gehad met een sterke tot extreme hittestress condities (35 tot 45 °C PET, zie Grafiek 1). Op de drie andere locaties verminderen boomkronen de hittestress tot licht of niet aanwezig. Verharde locaties blootgesteld aan de zon warmen op en verminderen het thermisch comfort verder door de werking van infraroodstraling. De uitkomsten van de enquête maakt het belang van het goed reguleren van het thermisch comfort op de KMP zichtbaar.
Urban flooding and thermal stress have become key issues formany cities around the world. With the continuing effects of climatechange, these two issues will become more acute and will add to theserious problems already experienced in dense urban areas. Therefore, thesectors of public health and disaster management are in the need of toolsthat can assess the vulnerability to floods and thermal stress. The presentpaper deals with the combination of innovative tools to address thischallenge. Three cities in different climatic regions with various urbancontexts have been selected as the pilot areas to demonstrate these tools.These cities are Tainan (Taiwan), Ayutthaya (Thailand) and Groningen(Netherlands). For these cities, flood maps and heat stress maps weredeveloped and used for the comparison analysis. The flood maps producedindicate vulnerable low-lying areas, whereas thermal stress maps indicateopen, unshaded areas where high Physiological Equivalent Temperature(PET) values (thermal comfort) can be expected. The work to dateindicates the potential of combining two different kinds of maps to identifyand analyse the problem areas. These maps could be further improved andused by urban planners and other stakeholders to assess the resilience andwell-being of cities. The work presented shows that the combined analysisof such maps also has a strong potential to be used for the analysis of otherchallenges in urban dense areas such as air and water pollution, immobilityand noise disturbance.
