Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant for humans. In the ‘Really cooling water bodies in cities’ (REALCOOL) project thermal effects of typical Dutch urban water bodies were explored, using ENVI-met 4.1.3. This model version enables users to specify intensity of turbulent mixing and light absorption of the water, offering improved water temperature simulations. Local thermal effects near individual water bodies were assessed as differences in air temperature and Physiological Equivalent Temperature (PET). The simulations suggest that local thermal effects of small water bodies can be considered negligible in design practice. Afternoon air temperatures in surrounding spaces were reduced by typically 0.2 °C and the maximum cooling effect was 0.6 °C. Typical PET reduction was 0.6 °C, with a maximum of 1.9 °C. Night-time warming effects are even smaller. However, the immediate surroundings of small water bodies can become cooler by means of shading from trees, fountains or water mists, and natural ventilation. Such interventions induce favorable changes in daytime PET.

As a consequence of climate change and urbanization, many cities will have to deal with more flooding and extreme heat stress. This paper presents a framework to maximize the effectiveness of Nature-Based Solutions (NBS) for flood risk reduction and thermal comfort enhancement. The framework involves an assessment of hazards with the use of models and field measurements. It also detects suitable implementation sites for NBS and quantifies their effectiveness for thermal comfort enhancement and flood risk reduction. The framework was applied in a densely urbanized study area, for which different small-scale urban NBS and their potential locations for implementation were assessed. The overall results show that the most effective performance in terms of flood mitigation and thermal comfort enhancement is likely achieved by applying a range of different measures at different locations. Therefore, the work presented here shows the potential of the framework to achieve an effective combination of measures and their locations, which was demonstrated on the case of the Sukhumvit area in Bangkok (Thailand). This can be particularly suitable for assessing and planning flood mitigation measures in combination with heat stress reduction.

Vijf studenten aan Hogeschool Van Hall Larenstein (VHL) hebben in 2019/2020 als onderdeel van de minor ‘Bomen en Stedelijke Omgeving’ onderzoek uitgevoerd naar het effect van groen/beplanting op de gevoelstemperatuur in 'bloemkoolwijken'. De opdrachtgever voor dit onderzoek was dr. ir. Jelle Hiemstra van Wageningen University & Research. Op het gebied van ENVI-met kregen zij begeleiding van dr. ir. Cor Jacobs van Wageningen University & Research, die hen hielp met het bouwen van het model en het berekenen van de temperatuur, luchtvochtigheid, windstromen en gevoelstemperatuur. De studenten werden begeleid door docent dr. Mart Vlam. Dit artikel is geschreven op basis van vragen die ex-redactielid Jozé ’t Hoen en redactielid Jaco Houweling de studenten hebben voorgelegd.

Een actuele ontwikkeling binnen ziekenhuizen is de opkomst van een 'healing environment'. In een healing environment waant de patiënt zich niet noodzakelijkerwijs voortdurend in een ziekenhuis. Zo'n omgeving draagt bij aan de welzijnsbeleving en het natuurlijke herstelproces en verkort daardoor de verblijfsduur in het ziekenhuis.

Een op de vijf entreestudenten en bijna een op de 10 mbo niveau 2 studenten stopt voortijdig met de opleiding (DUO, 2022). Uit eerder onderzoek (Baay, 2015; Slagter & Van Veldhuizen, 2021) blijkt dat studenten op entree- en mbo 2-niveau weinig gebruik maken van de aanwezige hulpbronnen, dat wil zeggen buiten de docenten van hun opleiding. Dat maakt de afhankelijkheid van entree- en mbo-niveau 2 studenten van hun docenten hoog. Om de positieve ontwikkeling van entree- en mbo-niveau 2 studenten te vergroten, lijkt het wenselijk om tijdens de mbo-opleiding meer aandacht te besteden aan het leren van alternatieve oplossingsstrategieën, buiten het vragen van hulp aan de docent. Om scherper in beeld te krijgen wat dit vraagt van mbodocenten, is een verkenning op dit thema gestart door MBO College Centrum (ROC van Amsterdam) in samenwerking met het lectoraat De Pedagogische Opdracht van Hogeschool Inholland.

In recent years, the effects of the physical environment on the healing process and well-being have proved to be increasingly relevant for patients and their families (PF) as well as for healthcare staff. The discussions focus on traditional and institutionally designed healthcare facilities (HCF) relative to the actual well-being of patients as an indicator of their health and recovery. This review investigates and structures the scientific research on an evidence-based healthcare design for PF and staff outcomes. Evidence-based design has become the theoretical concept for what are called healing environments. The results show the effects on PF and staff from the perspective of various aspects and dimensions of the physical environmental factors of HFC. A total of 798 papers were identified that fitted the inclusion criteria for this study. Of these, 65 articles were selected for review: fewer than 50% of these papers were classified with a high level of evidence, and 86% were included in the group of PF outcomes. This study demonstrates that evidence of staff outcomes is scarce and insufficiently substantiated. With the development of a more customer-oriented management approach to HCF, the implications of this review are relevant to the design and construction of HCF. Some design features to consider in future design and construction of HCF are single-patient rooms, identical rooms, and lighting. For future research, the main challenge will be to explore and specify staff needs and to integrate those needs into the built environment of HCF.

Zorg op afstand kan ouderen helpen om langer zelfstandig thuis te wonen. Maar zolang verpleegkundigen niet weten hoe zij zorg op afstand moeten verlenen, heeft deze zorgverlening - met gebruik van eHealth-technologie - weinig waarde. Over eHealth wordt veel geschreven, maar eHealth is niet per se populair onder verpleegkundigen. Hoe komt dat? Wat weerhoudt hen van deze innovaties? En hoe krijg je verpleegkundigen wél overstag? Cruciaal voor verpleegkundigen is dat de meerwaarde van eHealth voor hun cliënt evident is. ‘Draagt het bij aan de zorg van mijn cliënt, dan wil ik het wel inzetten’. In dit artikel bespreken we wat je met dit gegeven kunt als je nadenkt over het integreren van eHealth in het curriculum van verpleegkundestudenten. Er wordt geïllustreerd hoe eHealth-onderwijs eruit kan zien en welke uitdagingen hier nog liggen.

Adopted on the fifteenth anniversary of resolution 1325, Security Council resolution 2242 has recognized for the first time the substantial link between climate change and the “Women, Peace and Security” (WPS) framework. Despite this landmark resolution, the intersections of environmental factors, conflict and violence against women remain largely absent from the Security Council's WPS agenda. Competition over natural resources is generally understood as a driver of conflict. The risk of insecurity and conflict are further increased by environmental degradation and climate change. It is therefore clear that the environment and natural resources must be integrated into the WPS agenda. This should necessarily include a discussion of indigenous rights to land and the gender-related dimensions of environmental factors. Indigenous women are disproportionately affected by environmental degradation, caused by resource extraction and increasingly compounded by climatic changes. This in turn exacerbates other vulnerabilities, including sexual and gender-based violence and other forms of marginalization. This article argues, by reference to the situation in West Papua, that unfettered resource extraction not only amplifies vulnerabilities and exacerbates preexisting inequalities stemming from colonial times, it also gives rise to gendered consequences flowing from the damage wreaked on the natural environment and thus poses a danger to international peace and security. As such, the Security Council's failure to recognize the continuous struggle of women in indigenous and rural communities against extractive economies and climate change impact as a security risk forms a serious lacuna within its WPS agenda.
