2 SUMMARY Task 1: Reading texts from Oikomodos resources; Writting report Analysis of shrinkage s causes and possibilities front this problem Task 3: Densification in Berlin Historical evolution of the city, density study and strategies Task 4: Reduction in Cottbus Urban evolution of Cottbus and current urban structure

3 Task 1 Research SHRINKAGE: metropolitan area that experiences significant population loss in a short period of time. REASONS? - Deindustrialization - Emigrations - Aging population

4 Task 1 Research BENEFITS - Decongest the place - More public spaces - More public services to the neighbours DISADVANTAGES - Problems in the city borders and small cities - Physical isolation: disconnection from everyday amanities found in denser areas - Decreasing in the houses s development

5 Task 1 Research OPPORTUNITIES - Open space where generate an innovative design to reimagine neighbourhood patterns - Holes could be a good space used by the neighbours - Generating an amenity that change and give a new value to the neighbourhood

18 Task 4 Getting to know Cottbus

Task 4 Getting to know Cottbus Urban history 1945: IIWW Parts of the city were completely destroyed. 1945-1989 The city soon became important to the GDR s industrial development.

19 Task 4 Getting to know Cottbus Urban history 1945: IIWW Parts of the city were completely destroyed The city soon became important to the GDR s industrial development High demand of housing opportunities. The first large housing estate was built on the southern city edge of 1985 Cottbus youngest large housing estate, was built A strategy for urban restructuring that consisted on demolishing some buildings different parts of a whole district.

Task 4 Getting to know Cottbus Why is Cottbus an shrinking city? Deindustrialization. The failure of the post-industrial transformation process. Drop in the birth rate. Ageing. Suburbanization.

20 Task 4 Getting to know Cottbus Why is Cottbus an shrinking city? Deindustrialization. The failure of the post-industrial transformation process. Drop in the birth rate. Ageing. Suburbanization. Negative migration balance due to high unemployment rate. Why is a problem being a shrinking city? Deteriorate the fiscal base of cities. Maintaining local infrastructures. High degree of empty flats.

21 Task 4 Getting to know Cottbus What s the solution to stop shrinkage? Achieve a gradual economic shift: Leave behind the old manufacturing and move ahead with sophisticated high-tech industries. Focus more on its reputation as a city of science. Recover the old neighbourhoods and the historic centre focusing on single urban projects. Tear down abandoned or underused buildings and use that space as a green space or build there single-family homes. Build up highly competitive local industries. Stabilize the population.

22 Task 4 Getting to know Cottbus How can we do it? The best strategy for shrinking cities is to accept the shrinkage and to improve quality of life for the remaining residents. (Hospers,2014) There is a lack of open public spaces in the inner city. We can demolish some old abandoned buildings of this zone and use these vacant to create green public spaces. (Density decrease) Create a green structure that set up limits to the city size. Support for the establishment of local innovation networks and the creation of modern industrial and service clusters. Creating favorable working space. Enhancing touristic attraction of city center.

23 CONCLUSIONS Shrinkage and growth are not a problem in a city, they had to be opportunities that cities wouldn't have in a normal situation. Use them!! Best option to work in both situation is stitching urban fabric. Architect is a tailor that join the preexistence with new projects. One of the most important work for doing that is making a historical study and knowing neighbor s requirements. Cottbus won t grow anymore, we should consider the city situation as an opportunity to create a nice place to live. There are plenty of spaces that need to be rethought with a new point of view that led us to the future.
