The city is the most complex human creation shaped over the centuries. The human-nature-city relationship is the basic principle of city development. The main scientific challenge of the current urban planning approach is recognized in a broken human-nature-city relationship whose degradation is amplified in 21st century by globalization and rapid climate change. This challenge is addressed in this thesis through the history of city transformation analyzed in literature review. The

... n impact on human-city-nature relationship helped to define the missed opportunities and proposed a new approach in the management of the natural resources and Ecosystem Services [ESS] in the city. The thesis is focused on the mitigation of the following ecosystem services: Urban Heat Island (UHI) and improvement of public amenities. Moreover, through addressing these ecosystem services, other ESS (water management and climate change adaptation and mitigation) are improved as well. The UHI is selected as one of the most significant principle that influences human comfort in open public spaces. In order to increase the amenities in a city, a new approach is focused on the level of city blocks – neighbourhood level. This thesis translates and synthesizes literature knowledge into a new approach, and uses computer-based models to test them on two case studies and one demo site. The new methodology follows the rules of nature and affirms the potential of ESS. The integration of the blue [urban waters] and green [urban greenery] infrastructures is quantified by the use of the computer-based analysis of ESS indicators. The combined effects of the blue-green infrastructure reduce the degradation of living environment and increase amenities of open public space. The implementation and the testing of the theoretical models in practice, supported by computer modelling, confirm the above-mentioned statement. The results of the new methodology were tested on the demo site – Imperial College South Kensington Campus – in order to increa [...]
