CESARClimate and Environmental change and Sustainable Accessibility of the
Randstad
DBR February 2012
Prof. Martin Dijst
Faculty of Geosciences
Utrecht University
CESAR in a nutshell
Challenge 1
Challenge 2
Progress challenge 1
• Systematic and comprehensive review of literature
• Incomplete and fragmented
Progress challenge 1
continued
• Overall: increased attractivensess of cycling and decrease of the car
• Winter(milder and wetter): growth in use of cycling and walking
• Summer (hotter, dryer and extreme precipitation): more car and less use of active modes
• Sholder seasons: contrasting results
Progress challenge 1
continued
• What is more important for urban heat island effect?:
• Long wave trapping• Short wave shadow effects
• Based on collected data in Rotterdam and Weather Research and Forecast model (WRF)
• Effects depend on season:• Winter: only long wave trapping
due to lack of incoming solar radation
• Summer: both processes
Progress challenge 2
• Developing and testing multidimensional framework
• Aims of PSS• Improving planning process• Improving outcomes
• Experimental tests of Urban Strategy (US)
• Preliminary results• In its current form US contributes
little to the quality of the process and outcomes
• Scale and level of detail not well tuned to the demands of land use and transport strategy makers
• Kind of indicators not well-suited for kind of questions
Policy relevance
• Impact of microclimate on local environmental quality
• Impact of microclimate on sustainable transport modes
• Impacts on sustainable accessibility• Integration of microclimate effects in
PSS
Prospects challenge 1
• Fieldwork to analyse interaction weather conditions, individual experiences and mobility
• Modelling morphology of cities and urban climate
Prospects challenge 2
• Experimental testing specific strategies to improve quality of processes and outcomes of PSS
• Analysis of meaning of PSS at various spatial scales and for exchange of knowledge between various type of actors
