Accidental and surprising as it may be, the city of Ploiesti developed a rich green infrastructure. Find out what happened in this blog by Pieter Wieringa, a forest engineer from Romania.
The city of Ploiesti is the center of oil exploitation and oil refining in Romania, completely surrounded by oil and petro-chemical industries. At the beginning of the 20th century, when Romania was the third largest oil producer in the world, the city counted more than 10 oil refineries. Today only four of them are operational. Vast industries lay abandoned (brownfields), urban air quality is poor and greeneries are few.
Officially, Ploiesti only provides each and every inhabitant with 12,4 m2 of public functional green space, while the Romanian average of urban green space in cities with more than 100.000 inhabitants is 18 m2 per capita. Both are well below the minimum of 26 m2 per capita required by the European Union.
However, it is not as simple as that and the numbers can be deceiving. Working as a forest engineer on the new master plan for this heavily industrialized city, I realized that Ploiesti is actually very green indeed! The oil refineries and supporting chemical companies that have gone bust in the early 90s have turned green. In the 25 years of abandonment, plants and trees have become quite successful in reclaiming the lands. Nature has created urban wilderness woodlands or “nature of the fourth kind” as Ingo Kowarik and Stefan Körner named them so fittingly. The well-developed railway infrastructure was a facilitator in bringing plants and trees to areas of economic decline. The railways functioned as a sort of a transportation highway for exchange of genetic materials between the rural and urban areas.
The new wild urban woodlands follow the railways that encircle the city and in many cases connect to the adjoining brownfields. As a consequence, a near perfect unbroken greenbelt of 10 to 600 meters wide has emerged. The greenbelt is highly variable along its route. Its vegetation is in different stages of development and runs through mostly brownfields in the South, towards watershed and residential areas in the north. Furthermore, a South to North-West green corridor, lining the main boulevard, connects the city center with the greenbelt (Figure 2). One of the most important features of green infrastructure is connectivity. Connectivity is what enhances genetic exchange and allows fresh air to reach the interior of cities where urban heat islands are most prevalent.
Although this network of a greenbelt, brownfields, green rail corridors and existing parks is not managed, studied or even identified, it does not mean it isn’t there. It contributes significantly to the greening and the quality of life in the city by providing advantages such as: pleasant micro-climate, urban biodiversity, fresh (cool) air, shade, pollution uptake, carbon sequestration, etc.
Even though most of the green wilderness woodlands are not open to the public, a lot of them are surprisingly accessible. Recently, people have started to notice the sheer scale of (green) change and are beginning to see opportunities for its alternative use – recreation, adventure, parkour and skateboarding. It provides a space for wilderness experience and a welcomed contrast to the harsh and chaotic concrete urban environment. Additionally, many of these areas are used for pastoral activities and urban agriculture, further adding to urban resilience.
Urban forestry in Romania is in its infancy. There are no present discussions taking a more holistic view at urban green spaces in Ploiesti. Based on field research and existing information I was able to create the above map and gather data.
The greenbelt that surrounds the city occupies an area of approximately 7,2 km2. Together with other green spaces and parks the total surface of green infrastructure amounts to 13.26 km2. In other words, 22,7 % of the city is covered by greeneries. In total, the residents of Ploiesti will now find there is 63,1 m2 per capita of green space, out of which 12,4 m2 per capita of public functional green space. According to a previous study on urban green space coverage in Europe, these numbers rank Ploiesti higher than the Romanian average and the neighboring eastern European countries.
Accidental as it may be, could there be a way to integrate and protect these valuable resources in the future? How to raise awareness for something that is associated with unemployment, economic decline and mismanagement? Perhaps through temporary use of small physical impact, such as creating wilderness parks, community food forests or allotment gardens (urban agriculture)? What do you think the alternatives for Ploiesti’s green urban future can be?
