    The city region of Rotterdam is located in the western part of the Netherlands, bordering the North Sea. It contains the municipality of Rotterdam and several neighbouring municipalities, with about 1.2 million inhabitants. Rotterdam hosts Europe’s largest sea port as well as a large (inland-oriented) river port. Shipped through the ports into Europe (by barge, rail or lorry) are goods including food (e.g., exotic fruits and vegetables, juices, rapeseed and palm oil) and feed products (soybeans, grains, tapioca).

    This paper reports on temporal and spatial variability of local climate and outdoor human thermal comfort within the Rotterdam agglomeration. We analyse three years of meteorological observations (2010–2012) from a monitoring network. Focus is on the atmospheric urban heat island (UHI); the difference in air temperature between urban areas and rural surroundings. In addition, we calculate the Physiologically Equivalent Temperature (PET) which is a measure of thermal comfort. Subsequently, we determine the dependency of intra-urban variability in local climate and PET on urban land-use and geometric characteristics. During a large part of the year, UHI-intensities in densely built areas can be considerable, under calm and clear (cloudless) weather conditions. The highest maximum UHI-values are found in summer, with 95-percentile values ranging from 4.3 K to more than 8 K, depending on the location. In winter, UHI-intensities are generally lower. Intra-urban variability in maximum UHI-intensity is considerable, indicating that local features have an important influence. It is found to be significantly related to building, impervious and green surface fractions, respectively, as well as to mean building height. In summer, urban areas show a larger number of discomfort hours (PET > 23 °C) compared to the reference rural area. Our results indicate that this is mainly related to the much lower wind velocities in urban areas. Also intra-urban variability in thermal comfort during daytime appears to be mainly related to differences in wind velocity. After sunset, the UHI effect plays a more prominent role and hence thermal comfort is more related with urban characteristics.

    Reliable estimates of evaporative water loss are required to assess the urban water budget in support of division of water resources among various needs, including heat mitigation measures in cities relying on evaporative cooling. We report on urban evaporative water loss from Arnhem and Rotterdam in the Netherlands, using eddy covariance, scintillometer and sapflow observations. Evaporation is assessed at daily to seasonal and annual timescale. For the summer half-year (April–September), observations from Arnhem and Rotterdam are consistent regarding magnitude and variability of evaporation that typically varies between 0.5 and 1.0 mm of evaporation per day. The mean daily evaporative cooling rate was 20–25 Wm-2, 11–14% of the average incoming solar radiation. Evaporation by trees related to sapflow was found to be a small term on the water budget at the city or neighbourhood scale. However, locally the contribution may be significant, given observed maxima of daily sap flows up to 170 l per tree. In Arnhem, evaporation is strongly linked with precipitation, possibly owing to building style. During the summer season, 60% of the precipitation evaporated again. In Rotterdam, the link between evaporation and precipitation is much weaker. An analysis of meteorological observations shows that estimation of urban evaporation from routine weather data using the concept of reference evaporation would be a particularly challenging task. City-scale evaporation may not scale with reference evaporation and the urban fabric results in strong microweather variability. Observations like the ones presented here can be used to evaluate and improve methods for routine urban evaporation estimates.

    Based on the experience acquired in the Bergpolder Zuid district in the city of Rotterdam, The Netherlands, this paper presents lessons learned so far on science-policy interactions supporting the adaptation to climate change in an urban district. Two types of integration issues were considered: (1) Integration within science including integration of disciplines, methods, models and data, and (2) integration between science and the local stakeholders' society, involving a synthesis of scientific and practical knowledge, linking sectors, governance arrangements and organisations. At first sight, the issues around integration within science and beyond the science of climate change adaptation in cities resemble those generally observed in science-policy integration. However, the relative newness of urban adaptation to climate change poses specific challenges for both the scientists and the stakeholders involved in the process. The Rotterdam example discusses the use of multiple means of integration for enhancing integration between scientific disciplines and integration between scientific and stakeholder knowledge.

    Het klimaat verandert. Dit heeft ook voor Rotterdam gevolgen. De temperatuur in de stad zal stijgen waardoor steeds meer mensen last kunnen krijgen van hittestress. Hevige regenbuien komen vaker voor waardoor de kans op wateroverlast in de stad toeneemt. Tegelijkertijd neemt de lengte van droge periodes in de zomer toe, waardoor de grondwaterstand kan dalen. Voor een concrete praktijk case, Bergpolder Zuid, zochten wetenschappers en betrokkenen uit de praktijk samen uit hoe kwetsbaar de wijk is voor klimaatverandering en welke adaptatiemaatregelen de klimaatbestendigheid zouden kunnen vergroten.

    Rethinking barriers to adaptation: mechanism-based explanation of impasses in the governance of an innovative adaptation measure

    Many of the possible barriers in the governance of climate change adaptation have already been identified and catalogued in the academic literature. Thus far it has proven to be difficult to provide meaningful recommendations on how to deal with these barriers. In this paper we propose a different perspective, with different epistemological assumptions about cause and effect than most existing barrier studies, to analyze why adaptation is often challenging. Using the mechanismic framework, we study how the idea for an innovative ‘‘Water Plaza’’ was realized in the city of Rotterdam, the Netherlands. Mechanisms are understood as patterns of interaction between actors that bring about change in the governance process that lead to policy impasses. Our analysis reveals three mechanisms that explain the impasses in the first Water Plaza pilot project: the risk-innovation mechanism, the frame polarization mechanism, and the conflict infection mechanism. Only after several substantive changes in the project design, location choice, and process architecture was the project of Water Plaza’s revitalized. We discuss how the short-sighted ideas about cause–effect relationships, reflected in the superficial identification of barriers, may prove to be counterproductive; if there is high uncertainty about the risks of an innovation, the solution of offering more certainty is not very helpful and could, as it happened in the case study, trigger other mechanisms, creating an even tighter deadlock. Our study also suggests that when adaptation is considered as something innovative, the chances will increase that the risk-innovation mechanism will occur. We conclude that unearthing mechanisms offers new opportunities and different types of strategic interventions in practice than most existing studies have offered.
    Spatial variability of the Rotterdam urban heat island as influenced by urban land use

    Novel bicycle traverse meteorological measurements were made in Rotterdam to assess the spatial variation of temperature during a tropical day. Nocturnal spatial urban temperature differences of 7¿K were found to be related to city morphology. The coolest residential areas were green low-density urban areas. During midday measurements the downtown was up to 1.2¿K warmer than the surrounding rural area while a city park was 4.0¿K cooler than downtown. A regression analysis showed that the nocturnal measured urban heat island (UHI) can be linked to land use, namely plan area fraction of vegetation, built up area water and is most significant for vegetation. The vegetated area was derived from visible and near infrared aerial images. Neighbourhoods with vegetation (within an upwind radius of 700¿m) had a significantly reduced UHI during the night. From the traverse observation data a multiple linear regression model was constructed and independently validated with 3-year summertime UHI statistics derived from 4 urban fixed meteorological stations. In addition, two fixed rural stations were used; a WMO station at Rotterdam airport and a rural station further away from the city. Wind rose analysis shows that UHI is strongest from easterly directions and that the temperature signal of the WMO station is influenced by an UHI signal from both the airport runways and urban directions. A regression model reproduced the nighttime spatial variability of the UHI within a fractional bias of 4.3% and was used to derive an UHI map of Rotterdam and surroundings. This map shows that high density urban configurations lacking greenery or close to large water bodies are vulnerable to high nocturnal temperatures during heat waves. This warming effect of water bodies is also evident for an urban weather station located in the harbor area, which had a similar nocturnal UHI frequency distribution as the downtown urban weather station. The UHI map can be used as a valuable planning tool for mitigating nocturnal urban heat stress or identifying neighborhoods at risk during heat waves.
    Evaluating the effect of flood damage-reducing measures: a case study of the unembanked area of Rotterdam, the Netherlands

    Empirical evidence of increasing flood damages and the prospect of climatic change has initiated discussions in the flood management community on how to effectively manage flood risks. In the Netherlands, the framework of multi-layer safety (MLS) has been introduced to support this risk-based approach. The MLS framework consists of three layers: (i) prevention, (ii) spatial planning and (iii) evacuation. This paper presents a methodology to evaluate measures in the second layer, such as wet proofing, dry proofing or elevating buildings. The methodology uses detailed land-use data for the area around the city of Rotterdam (up to building level) that has recently become available. The vulnerability of these detailed land-use classes to flooding is assessed using the stage–damage curves from different international models. The methodology is demonstrated using a case study in the unembanked area of Rotterdam in the Netherlands, as measures from the second layer may be particularly effective there. The results show that the flood risk in the region is considerable: EUR 36 million p.a. A large part (almost 60 %) of this risk results from industrial land use, emphasising the need to give this category more attention in flood risk assessments. It was found that building level measures could substantially reduce flood risks in the region because of the relatively low inundation levels of buildings. Risk to residential buildings would be reduced by 40 % if all buildings would be wet-proofed, by 89 % if all buildings would be dry-proofed and elevating buildings over 100 cm would render the risk almost zero. While climate change could double the risk in 2100, such building level measures could easily nullify this effect. Despite the high potential of such measures, actual implementation is still limited. This is partly caused by the lack of knowledge regarding these measures by most Dutch companies and the legal impossibility for municipalities to enforce most of these measures as they would go beyond the building codes established at the national level.

    Gebaseerd op de aanwezige literatuur is voor dit onderzoeksproject een theoretisch kader opgesteld, met daaraan gekoppeld een aantal hypothesen. Hierin speelde, naast het groene(re) karakter van het schoolplein, ook de grotere variatie in het aanbod van speelmogelijkheden een belangrijke rol. In de onderzoeksopzet zijn vier scholen in Rotterdam geselecteerd, waarvan het schoolplein groen zou worden heringericht. Dit betreft de Hildegardisschool, de Nicolaasschool, de Prinses Margrietschool en de Theresiaschool. Daarnaast is er een controleschool geselecteerd waar niets zou veranderen (Augustinusschool). Op deze scholen hebben op verschillende momenten metingen plaatsgevonden. In totaal zijn er bij een voormeting in het najaar van 2010 meer dan 300 kinderen geïnterviewd.

    Op vier basisscholen, gelegen in Rotterdamse aandachtswijken, is het effect van het groen herinrichten van het schoolplein op de kinderen onderzocht. Een vijfde school fungeerde als controleschool. Het onderzoek bestond uit een voormeting en twee nametingen, waarvan de eerste direct na de herinrichting en de tweede een jaar later plaatsvond. Per meetmoment zijn tegen de 300 kinderen bevraagd en getest, voornamelijk uit de middenbouw (groepen 3, 4 en 5). Niet elke herinrichting bleek even succesvol, bezien door de ogen van de kinderen. Daar waar dit wel het geval was, werd bij de eerste nameting een effect op het sociale klimaat op het plein gevonden en bij de tweede nameting een effect op het welzijn van de kinderen

    Haaglanden en Regio Rotterdam zijn beide sterk verstedelijkte gebieden met een hoge economische activiteit in de Zuidvleugel van de Randstad. Door de sterke verstedelijking en de hoge economische activiteit is het gebied gevoeliger voor weersextremen. Die grote impact van weersextremen is in het huidige klimaat al te merken. Voor een goed functioneren, is het van belang dat dit gebied zo is ingericht dat de meeste extremen in het huidige en toekomstige klimaat goed kunnen worden opgevangen zonder grote ontwrichtingen. Goede klimaatinformatie voor de regio is hierbij van belang.

    Urban agriculture is currently the focus of societal interest as a highly promising contribution to sustainable urban development. For many agricultural professionals, city-oriented services such as healthcare, education, hospitality and retail trade are interesting alternatives to expanding the scale of their farms. For individual urban residents, urban agriculture offers an easily accessible location in and around the city to relax, learn, work, meet others and engage in various forms of recreation. And for the neighbourhood, urban agriculture often means improvement of the physical and social environment.

    Beleefbare natuur en de kijkrichting Inpasbare natuur, zijn nader uitgewerkt in drie studiegebieden: de Drentse Hondsrug, de Oostvaardersplassen en omgeving, en Rotterdam-Zuid. De Drentse Hondsrug past momenteel al heel goed in deze kijkrichtingen. Voor de twee andere gebieden gaat het om een nieuwe manier van kijken naar de aanwezige natuur. Voor elk studiegebied is een mogelijke toekomst vanuit de kijkrichting Beleefbare natuur en vanuit de kijkrichting Inpasbare natuur beschreven. Om meer beleefbare natuur te realiseren, is vooral gezamenlijke visievorming en betrokkenheid van burgers nodig. Om meer inpasbare natuur te realiseren, is het nodig om vormen van governance te ontwikkelen die de samenwerking tussen ondernemers en overheden stimuleren. Hiervan worden diverse voorbeelden gegeven
    Anthropogenic heat release and Urban Heat Islands effects in Rotterdam, The Netherlands

    Recently, it gets broadly acknowledged that the release of heat due to anthropogenic activities (anthropogenic heating) is a major component of the urban energy budget. Anthropogenic heating is therefore one of the major causes of the additional heating of cities as compared to the surrounding rural areas, commonly known as the Urban Heat Island effect. In this study the effect of anthropogenic heating on the climate of the Dutch coastal town Rotterdam. The city of Rotterdam is quite special, as estimates by the Large scale Urban Consumption of energY (LUCY) model have revealed that anthropogenic emissions of the city and particularly the harbor area of Rotterdam are very high as compared to other cities in Europe. Also, the city of Rotterdam is interesting, as its meteorology of is rather complex due a multiple processes such as the interaction between the sea and the land, the availability of open water close to the city centre and other large cities and industrial area in its environment. To study the impact of anthropogenic heat sources on the urban meteorology of Rotterdam, detailed simulations of the urban meteorology of Rotterdam have been performed with both the 3D and the 1D version of the Weather Research & Forecasting (WRF) model/ This model incorporates a detailed description of the exchange processes between the urban surface and the overlying atmosphere, the so-called SLUCM model. From our simulations it becomes apparent that the effect of anthropogenic emissions on the UHI is (locally) significant. From our study it appears that the anthropogenic emissions contributes to UHI effect with values up to 1.5 K for an anthropogenic emission of 100 W m-2, locally emitted in the core of the industrial and residential heart of Rotterdam and the surrounding large cities.

    This paper gives a summary of research studying the impact of green vegetation and water surfaces on the urban heat island effect in Dutch cities. It appears that observations from both hobby meteorological stations, bike traverses and model results from 1D and a 3D WRF mesoscale model consistently estimate the cooling effect of urban green vegetation by 0.06 K/% vegetation cover. Surprisingly, enhanced water surface cover appears to increase the maximum urban heat island effect.

    Dit werkdocument gaat in op de effecten van (openbaar) groen op het Urban Heat Island Effect (UHI). Voor vijftien wijken in Rotterdam is een relatie gelegd tussen het bedekkingspercentage van verschillende hoogteklassen groen en de grootte van het UHI-effect. Er worden hierbij grote verschillen tussen de wijken gevonden. Voorts is voor drie buurten in beeld gebracht welke effecten het opgaande groen heeft op de hoeveelheid zonne-instraling die het straatniveau bereikt. Deze laatste bepaalt het comfort op straatniveau gedurende de dag.
