Urbanization and ageing are the two main processes currently shaping the social environment worldwide. In this context, creating senior friendly cities should be an important target, especially in developed countries, which have the highest rates of population over 60 years old. Our study focuses on the use of urban parks and aims to analyze how friendly their planning, design, and use are for elderly people. We used field observation carried out in four case study parks in Bucharest (Romania) to assess the spatial planning and design of urban parks, and to identify the environmental problems. We applied a total of 5752 questionnaires (16% to elderly people) in the majority of Bucharest’s parks in order to analyze the behavior and perception of seniors in contrast with that of the general population. The analysis highlighted the lack of endowments especially planned or designed for seniors and the multiple problems deriving from their interaction with other visitor groups which make them feel disrespected or unsafe. Our study highlights the need for including the needs, demands, and desires of elderly people in decision making processes, with the aim of creating inclusive and senior friendly parks.

Faced with growing economic, social and environmental challenges, urban settlements increasingly use green areas in the search for achieving sustainability and resilience. The first step is typically the development of policies and strategies that include a significant green component. This present study analyses the development policies and strategies of 213 Romanian cities and how they approach urban green areas as well as applied means of development and management. We constructed a database with information extracted from these documents, applied descriptive statistical analysis and mapped the resulting distribution of indicators. Results indicated the preference of local urban administrations for simple objectives such as increasing or maintaining surfaces of green areas but lacking activities for achieving identified targets in improving the multifunctional benefits of green areas. We concluded that there are no differences in approaches using geographical settings or urban ranks. We determined that further research is required to connect policies and strategies with their subsequent implementation at a local level and the ensuing perceived effects. Results are critical in analysing the performance of local authorities in weak planning systems common in south-east European countries.

The importance of small urban green areas has increased in the context of rapid urbanization and the densification of the urban tissue. The analysis of these areas through remote sensing has been limited due to the low spatial resolution of freely available satellite images. We propose a timeseries analysis on 3 m resolution Planet images, using GEOBIA and vegetation indices, with the aim of extracting and assessing the quality of small urban green areas in two different climatic and biogeographical regions: temperate (Bucharest, Romania) and mediterranean (Athens, Greece). Our results have shown high accuracy (over 91%) regarding the extraction of small urban green areas in both cities across all the analyzed images. The timeseries analysis showed consistency with respect to location for around 55% of the identified surfaces throughout the entire period. The vegetation indices registered higher values in the temperate region due to the vegetation characteristics and city plan of the two cities. For the same reasons, the increase in the vegetation density and quality, as a result of the distance from the city center, and the decrease in the density of built-up areas, is more obvious in Athens. The proposed method provides valuable insights into the distribution and quality of small urban green areas at the city level and can represent the basis for many analyses, which is currently limited by poor spatial resolution.
