Maps 2015 (3) Bogota

I’m clearly used to read maps and deduce such things as differences in building heights from a planar view. But sometimes it is clearly better to see what this means in a 3D view. According to cadastral data, this is how central Bogota (Colombia) looks like in terms of built bulk. The background map is from SOM, and altimetry data is SRTM.

Biblio (104) A book on the Chile National Urban Planning Award

Premio Nacional de Urbanismo Chile

I’m fully aware I’ve just written about this same subject just a few days ago; here it is about a monograph on the recipients of the award since the first edition. As I mentioned, this award has been clearly irregular along time. An award first attributed in Chile in 1971 and kept in hold until 1996 is as if it was first attributed in England in 1978 to have a second edition in 1998; sometimes the debate about ideas is transposed to the political landscape in such a way as to make some matters irrelevant for a time.

I have no reason to doubt of the interest for the Chilean nation of the works of each award recipient, but I will focus on the highlighted works; the first time it was a social housing project, the second one a metropolitan and infrastructure planning experience, and the following ones integrate increasingly sustainable development and public participation.

On awards (4) Chile National Urbanism Award

In 1971 the Housing and Urbanism Ministry of Chile established the National Urbanism Award; since 1996 the Colegio de Arquitectos (the professional board of Chilean architects) is also part of the organisation. The Award must recognize architects and other professionals that have shown excellence, creativity and substantial contributions to improve the quality of life in the cities of the country.

Up until now it has not followed a regular schedule, with six awards since 1971. The winner in 2014 has been Sergio Baeriswyl Rada, an architect who has worked in the Bio Bio region. A public servant at the city of Conception (224.000 residents) since 1994, he has directed its Plan Regulador, which was innovative in using a public participation strategy and a corridor structure. He has been recently involved in the regeneration of the Bio Bio seashore after the 2010 earthquake and tsunami.

Beyond the personal award, that I assume is justified, I will focus on the plans. I have never visited Chile, so what I say comes from an analysis of secondary sources. The Plan Regulador de Concepción defines (according to its bylaws as published in the municipal website, including amendments up to September 2009) areas which are subject to natural and anthropic risks; on these areas any project shall be preceded by a risk assessment, but there is no outright ban on building. This may seem strange to a layman, but it happens in many countries, as sometimes the safe areas are not in a convenient place; just think of Paris, when there are relevant underground quarries that are no longer exploited but create risk situations, or most of England, where floods are common on urban areas. In spite of that, in Europe there is an evolution towards a total ban on building on risk areas whenever feasible, as for instance this is impossible in most of the Netherlands.

The plans for the coastal populations, prepared after the tsunami, define areas in which homes and public facilities are forbidden, and it seems a good measure.

Biblio (93) National Urban Development Policy, Chile

biblio 93- politica urbana chile

This year the new Chilean national policy on urban development has been enacted. As it has been approved under the now former president Sebastian Piñera, its effective application remains to be seen, but it is anyway an interesting document to understand the country.

As in many Latin American countries, since the 1980s there has been a relevant economic growth with effects for all the population, even if Chile still has clear inequalities. Current urban problems come largely from urban management decisions taken in a rush to solve urgent issues, without enough reflection, something that can hardly be confined to that country. There are positive signs in terms of sustainable development, as the growing share of multilevel housing and the contention of sprawl. But environmental protection and heritage conservation are in trouble, and housing remains, despite all the clear improvements, a challenge, with a deficit of about half a million dwellings in a country of some 17 million residents. Let’s not forget that in 2015 the goal of 100% sewage waters treatment could be achieved, not a small feat for any country.

Biblio (89) Rental housing in Latin America

biblio 88-vivienda alquiler

The Interamerican Development Bank has just published a work by Andrés G. Blanco, Vicente Fretes Cibils and Andrés F. Muñoz on the relevance of rental housing for Latin America. The document includes a description of the problems of housing in the region and the potential benefits of rental units; the current state of rental housing in the area; and policy recommendations regarding offer, demand and juridical framework.

Monterrey has long had the image of the industrial powerhouse of Mexico. From the 1980’s there has been a tentative to build a more positive image, beyond smoke columns. First it was the Macroplaza (some 500 m of gardens connecting the main power centers and the classical museums, not unlike some US squares in a typology quite different from European Squares), and the the Parque Fundidora, an old steel mills site which has been turned into a park. Since the mid 1990s there has been a series of works to revive the canal de Santa Lucía, an ancient small river that has been turned in a navigable channel and linear corridor connecting both spaces; the Rio Santa Catarina, which is the main water course in the city, has been transformed in a linear park, but seems less well cared for . According to many sources, these possitive investment in public spaces have not been in parallel with much needed improvements in basic urban facilities in most of the urban tissue, as it has been the case in other cities also confronting a productive transportation (cities located in richer countries, no doubt).

Industrial traditions (2) Steel, rail and textile

Lille grew by a combination of industries, mainly the textiles ; Bilbao and Monterrey were clearly two steel cities, and Chattanooga, as Glenn Miller reminds in his song, grew by the rail. When industries got into trouble and pollution was deemed horrible (Bilbao and Chattanooga were not helped by scenic, but impractical hills for that matter), they became problem cities. What is interesting is to see how they avoided becoming a Detroit (whose story is still running…).

Industrial traditions (1) A sample

Old industrial cities in what we call usually the “western countries” are often an exemple of how hard it is to maintain an economic health on the long term, but also that this is achievable. Monterrey is still a reference in the Mexican industrial landscape. Chattanooga seems to be succeeding its transition to a more viable economic model. Lille tries to reinvent itself as a reference node in the European High Speed Train network, and Bilbao has in fact changed its image thanks to a museum that is, in fact, just the tip of the iceberg.
