Ecology-related resilience in urban planning A complex approach for Pecs (Hungary)

The aim of this paper is to introduce an urban planning methodology which enables planners to select projects, which fit the main goal of the city and develop a resilient strategy structure, based on the selected projects. The planning process is demonstrated by the development of a resilient city strategy - in this case, by the city of Pecs. The main goal of a city (in the case of Pecs: to become a sustainable city) determines policy directives and the functional areas involved, whilst the strategic goals and sub-goals of the functional areas influence projects. These projects generate impact flows, which provide the basic data for Ecological Network Analysis to measure the basic resilience of the strategy structure. It is known from ecological systems that neither totally redundant nor highly efficient systems are sufficiently resilient. ENA allows an optimisation procedure to be undertaken. As a result, a complex iterative model is devised, suitable to elaborate a resilient strategy structure. This paper shows that efforts to achieve sustainability can be used to organize resilient structures. The study applies this locally - where city strategy pursues sustainable aims - and globally, where existing global knowledge will be organized into a resilient structure.
