Green/Blue Infrastructure of the urban area of the river of Tirana, ALBANIA

Name	Green/blue infrastructure in north of Tirana
Country	Albania
City	Tirana
Authors	Mirsa Gishti, Bahman Nahri, Nataly Montoya, Paulina Nickl

Rationale: Blue/green infrstructure-connecting the historic centre with the national park

The river of Tirana is located between the historic centre and the National Park of the Paskuqani in northern part of the city. It is one of the 5 developing poles of the multicentric masterplan of the city approved in 2012. The population is expeted to increase during the next years, according to the demographic data and this fact makes the river`s zone a potential area of high density and multifunctionality in the future. The landscape is shaped mostly by natural and seminatural features like hills, the river and the park. Currently informal buildings, waste pollution and low mantainance of ecologic environment has become a very big problem to solve. It is an emergency to approach the future development of the area based on a well integrated green/blue infrastructure project since nothing has been done in this aspect and planning is always a better choice than improving when is too late.

Overview of the city

Tirana, the capital of Albania, is situated 40 kilometers from Durres, the largest port in the country and 26 km from Mother Theresa International Airport. It is the largest city, with an increasing population, with an average annual growth rate of 3.77% from 2001–2009 (INSTAT, 2009). The faster urbanization influences the city's development, the living environment and the socioeconomic situation.Tirana has the opportunity to be regenerated itself after a long term of isolation. Exists a lot of informality in the northpart of the city, but this informality is supposed to be the shelter for those persons who live there.

Biogeography of the area

Tirana‟s contact with water is concretized in two lakes (one in north and the other in south) and two rivers (Tirana River and Lana River) that run parallel to each other, between the two lakes. The actual condition of the Tirana River waterfront is weak and the regeneration of it is an important issue for the development of the city.

Its north-south axis, which eventually corresponds to the main boulevard of the city, serves as a connector between the lakes and the rivers. Existing general land use of the area under study and identification of the water surfaces of Tirana city. (Source: GrimShaw analysis and Dar analysis for Tirana Masterplan 2012) “Tirana in the XVI century was defined by a building mosque, a hammam and a bakery,” (Aliaj, Myftiu & Lulo, 2003). So, water was not the most important factor in the foundation of the city, but it was one of the natural resources affecting the growth of its early settlements and melding its future. In the actual situation, there do exist a close relationship between the water and the city. Like other natural elements (Dajti Mountain, hills, agriculture etc.) water influences the urban development and the stratum of the urban fabric.

The urbanization process happens on both sides of the Lana and Tirana River, around lakes. Tirana‟s green regions are strengthened by the topography besieging the urban superficies, the streets, the habitation areas etc. The source of Tirana River is in the mountains to the east. It flows to west through the northern area of the city. In the mountains, it flows through the protected area of Dajti Mountain, providing an ecological corridor, through which wildlife can extend and survive. Its estuary is 30-40 km to the north-west at Rodon Bay, on the Adriatic coast. The topography of Tirana from east to west is nearly 1% slope. The existing natural movement results fast during periods of rainfall, which combined with coarse sand and cobbles by the mountains located close, becomes a destructive force.

After the centralized society dropped to the market economy in the ‟90s, Tirana, as many other postsocialist cities of Europe, experienced an extensive growth by the congestion of the new population that settled in the periphery of it, which was not well incorporated into the urban life of the city. This decentralized action induced spontaneous settlement by the citizens, with their own resources, the same as it did in different places of the world, including Bogota, Bombay, Caracas etc., which suffer from a high percentage of informality. In Tirana, the social and spatial pattern viewpoint of the phenomena is little investigated.

---

The informal settlements (Kamza, Bathore and Paskuqan, the three major informal housing settlements around Tirana, with over 90% of the dwellings constructed illegally), grew mainly in the early 2000, in suspicious and poor conditions. This gave birth to an “informal city”, which was not acknowledged by the authorities, a self-made structure by rural immigrants which saw Tirana as a better opportunity for their familiar and future life. This city grew without planning control, creating a spatial and cultural disconnection with the existing urban situation. The consolidation of the “selfadding- process” raises the problems of social injury which needs to be resolved. The sustainable development of these areas, the integration and consolidation need a better understanding of these problems, to go to the final solutions. “The segregation involves spatial separation of population groups and spatial separation reduces interaction among groups over space” (Newby, 1982).

The existing condition of the Tirana river waterfront One of these informal areas is that of the North Tirana (Tirana River area near Paskuqan). The current ecological situation of the urban Tirana River demonstrates waterways and aquifers, poor waste management, contaminated land, deforestation and sporadic urbanization. Ecologically it is poor. As the European and world's experience shows, many of the nowadays healthy river waterfronts, were polluted in the past, so the chances for reversing the natural state are high. “The peculiarity of Tirana stands in the fact that post-socialist socio-spatial transformations are better defined by Balkanization (implying individuality and hostility) rather than segregation (which implies clustering)” (Nase, Ocakçi. 2010). The public space is missing, as it is made property of the individuals which are settled in the area, property of each one alone, not along with the others. These individuals are interested in what evolves inside the fence of their houses and feel like lose character outside these borders. This kind of mentality makes citizens of this area distinguish by a special lifestyle, but not necessarily by good life quality. The rejection of sharing space with others leads to lack of social life, parks, recreational areas etc.. Currently, users of the Paskuqan Park (what is left from the public space) are relatively passive. Furthermore, squares and roads do not seem to provoke social cohesion, because of their structure, their main function of mobility and accessibility between different parts, their narrow or missing sidewalks, the unsafety they offer etc. The area speaks of a bad management of wastes and potentials (resources) too. For example; the natural lake of Paskuqan or the river of Tirana suffers from waste and lack of maintenance, although they have the opportunity to be a clear and real public space. Primary activities are missing, so the functions that take place are residential and rarely commercial

Green Infrastructure benefits for this site

Look again at the multiple benefits of green infrastructure - what could be achieved in your site and which are most relevant

The green infrastructure of this site aims to “restore” the river to its condition of natural value and texture. This action can be accomplished by removing rubbish and improve waste management. The result will be the encouragement of -social interaction, constitution of opportunities, tourist‟s attraction, introduction of activities and interventions platforms along the riverside area.

Potential for multifunctionality

Connectivity benefits:

1. Connection of people with the river /pedestrian paths

2. Connetion of the two sides of the rivers

3. With the future boulevard extension the north part of Tirana will become even more close to the centre and will connect it with the north park of

4. Good possibility for developing alternative transport system like tram and bicycle.

Summary of the collaborative process

Please reflect on your collaborative design process. Which potentials have you encountered? What was most difficult? What does collaborative design mean for you? (approx 150 words).

Reflecting our collaborative design process, this points mark clear what it means for us, and how we tried to handle it:

COMMUNICATION: As a team from all over the world, sometimes it was difficult for us to communicate. We managed it via Email and Skype. It was important to talk and not only chat by texting. Special in problem solving situations it was really helpful.

STRUCTURE: To manage the task, we decided to have a leader (Mirsa) who had the commando. We divided the project into different detail topics for each member to work on. So we had the possibility to get for the master plan four intensive worked out themes. Maybe for the next time we could add a more intensive project research, before working on the small topic. But all in all we worked effective and happy with our strategy.

MOTIVATION: The topic was new for three of us, but after talking and reading some research studies about Tirana River or Tirana Master Plan, we got into the project, too. Special because each of us was responsible for one topic, it was a good challenge to get motivated. Also combining the details in one master plan united us as a team.

SHARING: During the working process we get closed and learned about each other. Different levels and working experiences of the members caused an intensive communication how to deal with it. We think for all of us it was a good experience to share how to work, design, think about it in different ways and learn from each other.
