ENVIRONMENTAL PROBLEMS and DEVELOPMENT Residential areas with deficient access to urban parks in Bucharest – priority areas for urban rehabilitation CRISTIAN IOJA, MARIA PATROESCU, LIDIA NICULITA, GABRIELA PAVELESCU, MIHAI NITA, ANNEMARIE IOJA Centre for Environmental Research and Impact Studies, University of Bucharest 1 Nicolae Balcescu Blvd., Sector 1, Bucharest, ROMANIA Abstract: - The paper emphasizes the real dimension of the urban parks surfaces deficit upon the built environment in Bucharest city. There were established residential area categories with deficient access to urban parks of high quality, considered to be priority intervention areas for urban rehabilitation (residential areas situated at more than 3 km from municipal importance parks, at more than 1 km from urban parks, residential areas with access to crowded parks, or with access to parks that have degraded endowments). Deficient access to Bucharest urban parks was correlated with the development projects of new residential quarters, being obviously the tendency of city suffocation under the pressure of constructed surfaces and agglomeration. Key-Words: - urban parks, residential areas, housing, Bucharest, rehabilitation priorities areas 1 Introduction residential areas was completed by a tendency of Green spaces represent an essential component in vertical development, initially through 4 floors large urban environments, to which they offer constru-ctions, then 9 and 10 floors, in the present numerous direct and indirect services (improving reaching 20 floors. These new residential surfaces environmental quality, recreation and leisure, accentuated the real deficit of public green spaces. climate amelioration etc.) [1], [2], [3]. Green spaces deficit is expressed through the degradation of housing conditions in urban environments [1], [2], [3], automatically determining an increase of housing costs [4], a degradation of the population’s health state [5], [6] and the appearance of social segregation problems [7], [8]. Once called “the city of gardens”, Bucharest transformed in only 16 years in a real urban semi- desert, the green surface decreasing with 34,5 % between 1990-2006 (from 3471,2 ha to 2274,4 ha) [9], mean while the households and population increasing with 25 % [10]. The most important decreases (over 60 %) were recorded in the south of Bucharest (sectors 4 and 5), were it was already present an important deficit of green spaces (Fig. 1). In 2006, in Bucharest, the green spaces surfaces were of 2,274.38 ha (9.56 % of the city’s surface, respectively 11.8 m2 / inhabitant). From these 679.2 ha (29.9 % of the green spaces surfaces) were occupied by parks and public gardens, with an index of 3.51 m2 / inhabitant [9]. In the same time, residential areas had a strongly ascendant dynamic, developing especially on former Fig.1 – Urban parks distribution in relation with open spaces [11], [12].

According to the complexity of presented services, Bucharest urban parks were classified into parks of metropolitan importance (Herastrau, Tineretului, Titan, Cismigiu, Padurea Baneasa), municipal importance (Carol, Plumbuita, Circului, Gradina Botanica, Drumul Taberei, etc.), quarter importance with medium attractiveness (Obor, Motodrom, Gradina Icoanei, Ioanid, Pacii, Morarilor, Tei, etc.) and quarter parks with reduced attractiveness (Verdi, Crangasi, Pieptanari, Venus, etc.). Their spatial distribution isn’t regular, being noticed an agglomeration of urban parks in Bucharest’s northern and eastern parts (alongside Colentina). Areas with the most reduced accessibility to urban parks are found in the periphery, where de ascendant dynamic of residential surfaces is strongly expressed (Fig. 2). 2.2 Present rapport green spaces – residential spaces in Bucharest In Bucharest, residential spaces have suffered a special spatial and structural dynamics, with adjustments according to requirements, economics Fig.2 – Residential areas accessibility to parks of dynamic, residential mobility or plans promoted at metropolitan and municipal importance in Bucharest national or local level by state institutions or private economical agents [10], [15]. 2.3 The role of new residential projects and In 2002, in Bucharest were inventoried about the accentuation of green spaces deficit 780,000 housings, most of them (80.8 %) being The liberalization of the real-estate market allowed found in large residential ensembles (blocks).

Fig. 3 – Correlation between urban parks and new residential projects in Bucharest They are concentrated in areas with good accessibility to urban parks, but which are overcrowded. Thus, these residential spaces, besides their housing function, don’t create the infrastructure that will generate services necessary for maintaining a high standard of living, and instead are inserted on the already present infrastructure. For example, the housings from the micro-quarters Garden and Planorama will be serviced by the Plumbuita Park, where are already present real problems of overcrowding and the poor quality of the park’s infrastructures. Their finalization will bring an extra Fig. 4 – Categories of residential spaces with number of visitors in nearby parks, with direct deficient access to urban parks consequences on endowments quality and presented services. - residential spaces with access to overcrowded parks (48 % of the residential spaces) are found in 3 Residential areas categories the central area, the Drumul Taberei and Rahova quarters.
