Resumo(s)
The study of Quality of Life (Qol) has been conducted on various scales throughout the years
with focus on assessing overall quality of living amongst citizens. The main focus in these
studies have been on economic factors, with the purpose of creating a Quality of Life Index
(QLI).When it comes down to narrowing the focus to the environment and factors like Urban
Green Spaces (UGS) and air quality the topic gets more focused on pointing out how each
alternative meets this certain criteria. With the benefits of UGS and a healthy environment in
focus a new Environmental Quality of Life Index (EQLI) will be proposed by incorporating
Multi Criteria Analysis (MCA) and Geographical Information Systems (GIS).
Working with MCA on complex environmental problems and incorporating it with GIS is a
challenging but rewarding task, and has proven to be an efficient approach among
environmental scientists. Background information on three MCA methods will be shown:
Analytical Hierarchy Process (AHP), Regime Analysis and PROMETHEE. A survey based
on a previous study conducted on the status of UGS within European cities was sent to 18
municipalities in the study area. The survey consists of evaluating the current status of UGS
as well as planning and management of UGS with in municipalities for the purpose of getting
criteria material for the selected MCA method. The current situation of UGS is assessed with
use of GIS software and change detection is done on a 10 year period using NDVI index for
comparison purposes to one of the criteria in the MCA. To add to the criteria, interpolation
of nitrogen dioxide levels was performed with ordinary kriging and the results transformed
into indicator values. The final outcome is an EQLI map with indicators of environmentally
attractive municipalities with ranking based on predefinedMCA criteria using PROMETHEE
I pairwise comparison and PROMETHEE II complete ranking of alternatives. The proposed
methodology is applied to Lisbon’s Metropolitan Area, Portugal.
