Creation of an Integrated System Model for Governance in Urban MTEs and for Adapting Cities to Climate Change – preliminary results.
Xanthopoulou- Tsitsoni, Valia
Urban trees grow under adverse conditions, governed by the combinatorial effect of multiple natural and anthropogenic factors. Global climate change adds new challenges regarding urban green management that should be taken into account when designing future green urban policies. The development of a smart Information and Communications Technology (ICT) system and the establishment of a continuously up to date information system regarding urban trees is a key issue for future management which aims at: – climate change adaptation, by providing an instrument for measuring the cities CO2 emission offsets by CO2 sequestration of the tree biomasses; – efficient utilization of resources that are spent for urban tree management in order to decrease the cities’ environmental footprint; – enhancement of the cities’ social fabric by promotingcitizen participation during the decision making process regarding urban trees. The project was selected for funding after a competitive process by the General Secretary of Research and Development. The Municipality of Thessaloniki was selected as the key study area. The core of the project is the development of a software suite named GreenTree. Through the GreenTree client Android application, 105 different sets of data are collected for each urban tree. The urban tree inventory includes 37,328 tree sites on the pavements, from which we found 1,239 dead trees, 2,787 empty sites and 937 trees which had to be removed because they had been planted in inappropriate location and they disturbed the circulation of cars or pedestrians. The numbers above clearly show the significant need for the establishment of a reliable and smart monitoring system for urban tree management. This system could also help manage the decision making process. Finally, the numbers show that urban environment can be easily improved by applying fast and cheap measures of tree replanting and replacement
