Mapping the lockdown effects in India: how geographers can contribute to tackle Covid-19 diffusion

Partha Mukhopadhyay and Shamindra Nath Roy from the Centre for Policy Research co-authored this piece.


The reduction in the number of individuals commuting and travelling have without a doubt decreased the propagation of the coronavirus Covid-19 virus, as indicated by recent research.Conversation proposée par :

However, several articles underline the necessity to take into account urban and regional mobilities to better understand the emergence of infectious diseases in particular territories. The difficulty for the research community in considering such data contributes to the vulnerability of societies, notably in countries like India. However, preliminary results from ongoing research using social network data could be a first step to change this.

India under lockdown

India is divided in 32 states or union territories with a total population of 1.3 billion. The country’s economic development has led to the development of significant intra- and inter-regional mobilities.

Fractals, urban fabrics and planning – a few clarifications

Pierre Frankhauser, in answering the contribution from Cécile Tannier of 12 March point by point, supplements her discussion and fuels the debate:

Are urban fabrics fractal? Is there a general process that gives rise to fractal urban fabrics? Are fractal models useful for planning? These recently asked questions call for a reminder that, through its intrinsic properties, this approach can be used to introduce a different reading of the spatial organization of cities and to contribute otherwise to the debate on whether or not there are “laws” or whether “norms” are useful in this context.

Waldo Tobler (1930-2018)

From 1956, when he first published, to his passing on 20 February 2018, the teaching and publications of this Professor Emeritus had a major impact on several generations of geographers and cartographers. His work lives on since he is currently being rediscovered by some researchers and we can only wish for it to continue for a long time as Waldo Tobler has profoundly renewed and transformed cartography. He truly contributed to making cartography Conversation suggested by :

About fractal models in urban geography and planning: refuting the aesthetics and the universal norm

Fractal models have been used in urban geography for forty years. Their main applications were for analyzing urban forms but they were also used to simulate urban growth. Research in the field has significantly contributed to better characterise the local and global shape of cities and to better understand their evolutions. Yet concomitantly, one can deplore the circulation of some myths about the interpretation of fractal analysis results and

usage of fractal models for urban analysis and planning. I propose here to undermine some of these myths on the basis on some scientific publications in the field.

Should the ECTQG be institutionalized?

The 20th European Colloquium on Theoretical and Quantitative Geography was held in York from 7 to 11 September 2017. Organized by our colleagues from the University of Leeds, Michelle Morris, Mark Birkin and Nick Malleson, it brought together some 80 participants from 20 different countries, a large majority of Europeans but also a few colleagues from Canada, ChileConversation proposée par :

, the United States, Nigeria, Russia and Tunisia. The quality of the interventions leaves no doubt about the vitality of this non-institution, completely informal and self-organized, which holds symposium every two years since 1978! At least two articles in Cybergeo comment on the importance and sustainability, as well as the most salient meanings, that of David Unwin in 1999 and that of Sylvain Cuyala in 2016. We will remember from York in 2017 a tribute to the work of Sir Alan Wilson, and “Wilson’s boys” (John Stillwell, Frank Southworth, Martin Clarke, Mark Birkin and Michael Batty), the Consumer Data Research Center (CDRC), innovative applications in health geography, of the ESRC network for the study of obesity, supplemented by a conference by Anne Vernez-Moundon… and a variety of presentations by young researchers, all exciting, perhaps to be discovered one day in Cybergeo? Our blog is open to the discussion of proposals for thematic sessions for the next meeting, organized by Geoffrey Caruso of the University of Luxembourg. Grab your pens!
