How to protect a scarce ressource as farmland from urban sprawl? Swiss are trying ir this way
What do Germans think about when they think of energy, but also urban dynamics? a publication by their national programme for urban planning.
UNESCO published this text, by Alain Borie and François Denieul, in 1984. The World Heritage Convention was enacted in 1972, and the first properties were inscribed in 1978, so this is a rather early text in the production of the “world heritage” concept in its urban derivations.
This is a classical manual, based on the decomposition of the urban tissues in systems: lots, streets, buildings, open spaces… a lot of images in the final part.
Rural areas keep losing demographic weight around the “civilized world”. Here is a vision of the current condition in three French-speaking countries, with a special attention to urban planning issues.
After publishing the map on inequality in Spain, some comments have led me to think it could be interesting to show a comparative vision:
Spain: Renta personal de los municipios españoles y su distribución, Miriam Hortas Rico & Jorge Onrubia Fernández, FEDEA, 2014. Based on 2007 data
France: Les revenus et le patrimoine des menages, Cédric Houdré & Juliette Ponceau, edition 2014, INSEE. Based on 2011 data
USA: State of Disparity, a Project looking at the economic disparity in CT, WSHU radio (A view from Connecticut, but with a nationwide chapter). Based on data from 2006 to 2010.
Inequality is on the rise, but with different flavors in each country.
Here is a set of interesting references on long-term real estate prices in France, for the 1936-2015 period in the whole country and 1200-2015 for Paris. This vision in long-term series reminds me the long series on revenue on which Pikety supports his ideas.
Series from 1200 in Paris are evidently based on various methodologies, with a lesser statistic representatively. They show an erratic journey, but reality can sometimes be so.
So, I choose a large book by Microsoft, and I throw it to you, and it’s done… Well, it’s not just that. Authors say that science has evolved until now as a result of three paradigms:
- 1- Experimentation
- 2- Theory (since the XVIIth century)
- 3- Calculation and simulation (since the second half of the XXth century)
The massive use of big data would deliver that fourth paradigm. As the book is from 2009, we can now see it with some perspective.
Here is an article (page 20) we wrote three years ago for the Interamerican Development Bank. I just heard that Paris is to present an Olympic Bid in which regional planning would be an issue, so it came back to my mind…
This article by Molina, Rubio and Vecslir is based on academic works, and it addresses the evolution of the retail structures in both Latin- American megacities.
A report by the Urban Development and Resilience Unit of the World Bank, studying cases in Bangalore (India), Accra (Ghana), Nairobi (Kenya) and Lima (Peru). It seems that urban agriculture helps the first wave of migrants to cities, now old, to survive; it is also used by many as a complement to other sources of revenue, including informal jobs. Those urban farmers are usually the owners of the land they cultivate, and the reports sees reason to be optimistic about the development of this kind of agriculture.
