Cities are confronted with more frequent heatwaves of increasing intensity discouraging people from using urban open spaces that are part of their daily lives. Climate proofing cities is an incremental process that should begin where it is needed using the most cost-efficient solutions to mitigate heat stress. However, for this to be achieved the factors that influence the thermal comfort of users, such as the layout of local spaces, their function and the way people use them needs to be identified first. There is currently little evidence available on the effectiveness of heat stress interventions in different types of urban space.The Cool Towns Heat Stress Measurement Protocol provides basic guidance to enable a full Thermal Comfort Assessment (TCA) to be conducted at street-level. Those involved in implementing climate adaptation strategies in urban areas, such as in redevelopments will find practical support to identify places where heat stress may be an issue and suggestions for effective mitigation measures. For others, such as project developers, and spatial designers such as landscape architects and urban planners it provides practical instructions on how to evaluate and provide evidence-based justification for the selection of different cooling interventions for example trees, water features, and shade sails, for climate proofing urban areas.

Comprehensive understanding of the merits of bottom-up urban development is lacking, thus hampering and complicating associated collaborative processes. Therefore, and given the assumed relevancies, we mapped the social, environmental and economic values generated by bottom-up developments in two Dutch urban areas, using theory-based evaluation principles. These evaluations raised insights into the values, beneficiaries and path dependencies between successive values, confirming the assumed effect of placemaking accelerating further spatial developments. It also revealed broader impacts of bottom-up endeavors, such as influences on local policies and innovations in urban development.

Een holistisch perspectief op binnenstedelijke herontwikkeling Spatial Planning http://www.uu.nl/agenda/promotie-een-holistisch-perspectief-op-binnenstedelijke-herontwikkeling Promovendus Rien van Stigt onderzoekt waarom het moeilijk is om milieukwaliteit een prominente plaats te geven in de besluitvorming over ruimtelijke plannen. In zijn proefschrift ontwikkelt hij een holistisch perspectief op het complexe proces van compacte binnenstedelijke herontwikkeling. De kwaliteit van de stedelijke leefomgeving is essentieel in duurzame stedelijke ontwikkeling. Die kwaliteit staat met name bij compacte binnenstedelijke herontwikkeling onder druk, en daarom is milieukwaliteit een belangrijke factor in het plannen van zulke ontwikkelingen. Uit de literatuur over de integratie van milieubeleid blijkt dat dit, vooral op lagere bestuurlijke niveaus, niet altijd goed lukt. Er is nog geen overtuigende verklaring waarom dit zo is.
