1.1 Patterns of Urban Growth: Seminar at TU Wien in WS 2016-17 by Univ.Prof. Mag. Dr. Rudolf Giffinger

Prof. Dr. Rudolf Giffinger is Head of the Centre of Urban and Regional Research in the Department of Spatial Planning at TU Wien. As a geographer and regional scientist, he is an expert in urban and regional development and corresponding strategic advice. His research activities concentrate on polycentric development and metropolisation, with a special focus on infrastructure and innovations (Smart Cities) and their implications for sustainable and resilient development.

urban agglomeration of the country and contributes approximately 25% of its nominal GDP. Bogotá is considered the capital district of the country by the Colombian constitution, as long as it is the country’s seat of government and central national institutions. The city is also the administrative capital of the department of Cundinamarca, the territory surrounding it. Bogotá’s region expands over its neighboring municipalities, but is not clearly defined politically. Several authors and administrative documents describe its regional impact and main spatial relationships with a surrounded area involving 29 municipalities and their suburban agglomeration settlements.

Different to most European cities, Bogotá’s city center is not where the most expensive properties are located. During the past years, however, several projects have been implemented to renovate public space and attract more residents. An example of this is the Parque Central Bavaria, a residential and office complex located at the old production site of a beer brewery. Beside the mixed-use strategy, it enriched Bogotá by creating 20,000 square meters of public space: partly green space, partly space used for cultural events such as the Ibero-American Theater Festival or different concerts.

tivo de Planeación) from 1933 to 1948. He taught at the Universidad Nacional Bogotá, and then moved back to Vienna in 1948 to become the city’s planning director of Vienna and professor at TU Wien. One of the districts he designed during his work in Bogotá was Bosque Izquierdo. It is a typical example of how his creations Figure 2.14 - TU Vienna group walking at the Bosque Izquierdo.

follow the natural topography instead of the Spanish Colonial grid. He influenced BogotĂĄ particularly through the implementation of more organic urban fabric layouts enriched with green boulevards and gardens, with specific emphasis on the quality of the urban design at a neighborhood scale. Before moving to Colombia, Karl Brunner worked in Chile on different urban design and development projects and plans (1929 to 1934), and for the city of Panama (1940 to 1941). Figure 2.16 - Karl H. Brunner, 1955. Source: Ă–sterreichische Nationalbibliothek. 44

2.2.3 Rogelio Salmona 1929 - 2007

Rogelio Salmona was one of the most influential architects in Latin America. He was born in Paris in 1929, but soon moved to Bogotá with his family. Salmona studied architecture at the Universidad Nacional in Bogotá, but before finishing his studies he left Colombia and moved to France to work at Le Corbusier’s office. In his work he typically made use of various elements to point out the spatial conditions and potentials of a site or place, such Figure 2.18 -Torres del Parque, site plan. Source: Online, see list of figures. 46

2.2.4 La candelaria district

La Candelaria, the historical and foundational center of Bogotá, can be recognized by its Spanish Colonial architectural style. Besides residential and academic uses, the locality (district) La Candelaria also accommodates cultural institutions, such as the Biblioteca Luis Ángel Arango (public library) or the museum of the Banco de la República. In La Candelaria it is possible to feel a very vibrant, bohemian and youthful spirit, which manifests via street art forms such as graffiti.

2.2.5 suburbanization and conurbation trends: zipaquirá and usaquén

Although Bogotá’s rapid growth has led to the city’s urban densification, it also had a significant impact on its surroundings: The city border expanded and swallowed neighboring municipalities and towns such as Usaquén. This former suburban settlement was annexed by Bogotá not only through physical growth but also administratively, and transformed into an urban district in 1954. If this trend continues the town of Chía may soon face a similar future. Usaquén’s center is shaped by the Spanish Colonial architectural style, which is very similar to Figure 2.27 - Bogotá region: average rates of daily motorized mobility and road network.

The town of Zipaquirá, located about 22 km north of Bogotá, is particularly known for its underground salt mines, which were partly transformed into a large underground cathedral in 1991. The cathedral was designed by architect Roswell Garavito Pearl and is a large touristic attraction today. Along this north-south axis Figure 2.28 - Zipaquirá’s salt cathedral.

Bogotá is the academic center of the country and home to some of the most prestigious and topranked universities in Latin America. The Universidad Nacional de Colombia, University de los Andes and Pontificia Universidad Javeriana are among the most important academic and research institutions.

was designed by architect Leonardo Álvarez Yepes, winner of the Bienal de Arquitectura de Colombia in 2016. The campus owes its existence to the government of Liberal President Alfonso López Pumarejo, who reformed Colombia’s schools and universities between 1934 and 1938. His most important project was the reorganization and construction of the university town in Bogotá. López wanted an open university for students from all over Colombia. The German reform teacher, Fritz Karsen, was the first to conceive a comprehensive reorganization in pedagogical, scientific and economic Figure 2.34 - Pontificia Universidad Javeriana.

terms. Leopold Rother, an architect who emigrated from Germany in 1936, was commissioned to plan the campus. He envisioned the entire campus as a garden. The city within the city was designed as a southeast-northeast orientated oval with internal development roads. The university Pontificia Javieriana is located in the eastern part of the city in the district of Chapinero, at the foot of the eastern hills. Although the campus is adequately equipped with sporting, cultural and social facilities, it still remains open to the city, which is not very common for private institutions.

Bogotรก is a city with high urban density (195 inhab./hectare) and almost no space inside its urban limits with potential for further urban growth.

3.0 PREAMBLE: Medellín’s Geographical Characteristics

Medellín is the capital city of the department of Antioquia. In 2014, it had an estimated 2,311,092 urban habitants concentrated in 16 boroughs (called Comunas). Including its 5 rural municipalities, it was estimated that in 2017 its population is around 2,508,452 inhabitants (DANE). Medellín is the second largest city in Colombia with an urban area of 124.94 km², and including its rural areas (5 rural municipalities) a total of 382 km². The city’s average elevation is 1,500 meters above sea Figure 3.03 - From left to right, Colombia in the world, Department of Antioquia in Colombia, municipalities of the Valle de Aburrá metropolitan region (in red) in Antioquia, and Valle de Aburrá topographic visualization.

The river runs through the Aburrá valley, which is part of the central region of the Andes mountain range. Therefore, the city is also called ’la capital de la montaña’ (the capital of the mountain), due to its topography and hilly landscape. Because of its humid subtropical climate and its altitude, the mild and humid climate favors plant and flowers’ growth. Therefore, Medellín is also known as ’la ciudad de la eterna primavera’, the city of eternal spring, as well as ’la ciudad de las flores’, the city of flowers.

ecological balance of the surrounding ecosystems, which are essential to the city. Additionally, houses and shelters in those informal settlements are mostly built on unsuitable and unsafe sites (for instance along rivers and steep slopes). Inhabitants are thus endangered by several types of natural catastrophes, but especially landslides in times of heavy rain. The city council of Medellín started to react to this problem in cooperation with the affected Comunas and the city-administered planning office “EDU” (Empresa de Desarrollo Urbano), by implementing the concept of an urban green belt (Jardín Circunvalar – el cinturón verde de Medellín), surrounding the city on the slopes of

3.2.2.3 UVA de la Armonía & UVA Sol de Oriente: presented by Carlos Pardo & Camilo Restrepo

By contrast, the architects of EPM had a rather dissident approach and realized an extraordinary project: During the elaboration of an illumination master plan for the whole city, Carlos Pardo and Camilo Restrepo (on behalf of the whole EPM team) discovered that around 94% of Medellín is publicly illuminated. When investigating the parts of the city not lighted at night they came to realize that it wasn’t only small spots that were affected, but also large-scale areas. These areas were situated nearby water tanks, of which they found 144, Figure 3.22 - The UVAs’ locations in Medellín.

By integrating the dwellers and considering their ideas and requests

phase, a better communication process was implemented not only between the communities and the experts but also within the communities itself. The project enabled identification with the developed area and created open space for everyone. During workshops with the locals, needs and ideas were produced to refine the concept. As existing and uninhabited space was used, no one was forced to resettle. The project was financed by EPM (including public fees for gas and water connection) as a so-called social investment.

A big milestone in the park’s history was in 1985 when the botanical garden was declared cultural heritage. From 2005 to 2007 a renovation project was implemented in the whole area of the park. In addition to improvements in the garden and its flora and fauna, smaller projects on buildings were carried out. One of them was the renovation of the Patio de las Azaleas complex and the construction of the scientific building, the Orquideorama, the main access, the South American Theater, the House of the Butterflies, a small parking lot and the public space surrounding the garden (https:// www.botanicoMedellín.org/).

Graffiti in the streets of the Comuna still tell stories about the bloody disputes and Pablo Escobar’s drug imperium, but slowly they are replaced by new topics not reminiscent of the bloody times, but focusing on their own changes as a community and their not yet written futures.

3.2.4.2 Public library Presbitero & Comuna 13 escalators

The Bibliotheca San Javier is one example of the investments made by the city administration concerning public space and infrastructure in the Comuna 13. It was started in 2003 by Major Sergio Fajardo with the idea of fighting poverty with architecture. 40% of Medellín’s annual budget, approximately 900 million US-Dollars, is used for the education program “Medellín la Más Educada” that he established. Connected to the metro stop San Javier and the Metrocable line J, the library is one of five large library projects that were built in Figure 3.41 - The group during the visit to the Public library Presbitero.

3.3.2 Transformaciones integrales e innovacion social - EDU Medellín Presented by Arq. John Octavio Ortiz Lopera

The subsequent chapter examines the implementation of planning strategies that led to such successful recent urban development in the city of Medellín. In this context, the EDU - Empresa de Desarrollo Urbano - of Medellín has played an essential role. EDU can be defined as a “company for urban development”. The main task of EDU is to enhance the interaction between urban planning strategies of the public sector and the ideas of the citizens as well as the implementation of inFigure 3.64 - Before and after views of the 107Th Street.

6.1 From Bogotá to Medellín: route and main visited sites First day: From Bogotá to Santa Rosa de Cabal

Our excursion took us from Bogotá through the so-called “Coffee Triangle”

Medellín

(see Figure 6.02) to Medellín. With an estimated travel time of 15 hours, it finally took us 50% more time to traverse the distance of 617 km: On Saturday, we had

Salamina

lunch at a fish farm close to Ibagué, and due to a traffic accident close to La Línea

Manizales

we arrived late at night at Santa Rosa de

Santa Rosa de Cabal

Cabal, where we spent two nights. On Ibagué

Sunday, we had the opportunity to visit a coffee farm and enjoy the local hot springs. Monday led us past Manizales and a first stop at ZERI pavilion (made out of Guadua, a type of bamboo with great potential as a sustainable and enduring building material) to Salamina, a Colonial town and national monument founded in 1825, and, finally, Medellín. 196

This booklet summarizes an academic 15-day study visit to Colombia carried out in November 2016 by Master’s students and scholars from TU Wien, Faculty of Architecture and Planning. The aim of the visit was to explore different patterns of urban and metropolitan growth in Colombia, and the content of this booklet reflects the variety of insights gained during the excursion: From the academic program carried out in Bogotá with the Pontificia Universidad Javeriana’s Master program in Regional and Urban Planning and in Medellín organized by the Universidad Bolivariana’s Urban Design Lab, to complementary site visits. Urban growth and the role of planning are discussed, covering trends, challenges and how they may be addressed.
