Circulations, borders ans cities in the Guianas

November 7th to 9th 2018, University of French Guiana, Cayenne



Building on the work of researchers and specialists in the last decades, recent initiatives are revitalizing thought about the changes in the French Guiana’s borders, whether at the scale of French Guiana or the Guiana Shield (Blancodini P., 2010 ; Morel, Letniowska-Swiat, 2012 ; AUDeG, 2013 ; CAUE de Guyane, 2014 ; Carlin et al., 2014 ; Collomb & Mam Lam Fouk, 2016). The analysis of the borders has been focused on the geopolitical stakes for many years due to many border disputes, including the « contested conflict » between France and Brazil (Vidal de La Blache, 1901 ; Lézy, 2000 ; Granger, 2011 ; Théry, 2015 ; Ferretti, 2014) or between Venezuela and Guyana (de Vilhena Silva, 2017). The contemporary approaches no longer reduce boundaries to their status as limits between territorial entities. We can say that the Guianas’ borders, in particular fluvial, have a « thickness » (Agier, 2013), which allows them to be learned as spaces of exchange, active margins and creators of urban evolutions. Cross-border areas, which are often extended to the internal borders, constitute areas of mutation, where old socio-spatial structures interact with recent dynamics of settlement and development (das Chagas Martins et al., 2016). Thus, the purpose of this symposium is to question the transformations experienced by these border areas from the Amazon to the Orinoco. The attention will be focused on interactions between circulations, margins and cities in the Guianas, analysed according to three axes:

  • Circulations and mobilities
  • Borders and margins
  • Economic sectors and urban dynamics

This symposium is aimed primarily at researchers and young researchers in the social sciences (geography, economy, anthropology, sociology, history, political science). Languages used in the symposium are: French, English and Portuguese.

Abstracts of papers made in two of these languages (200 words, with five keywords) are expected by July 10, 2018.  

The deposit of abstracts is done on the website of the symposium :

The abstracts will be reviewed by the Scientific Committee and notices will be sent on September 15, 2018.

The LITEAU program calls for scientific papers as part of its next conference to be held on 14 and 15 January 2016 in Brest, in partnership with the National Research Agency, Ifremer and scientific interest group Hommer.

The conference addresses the renewal of the modes of knowledge production, particularly evolutionary and complex relationships between dynamic observation of the sea and coast, and thematic research currently being debated widely within OHM.

Given the critical state of biodiversity and exclusively mercantile relations and reified for much of human society to nature, is it possible to hope for a paradigm shift? Can we hope to take education very integrated and egalitarian relationships that companies have with améridiennes Nature? Ethics and proposed scientific solutions they can to change the economic and political pre-eminence?

According to Philippe Descola: "There are three matters critical to deal with the current crisis: ecology, anthropology and geography For these are the three science of interactions between humans and non-humans, they should occupy a very great.. place in secondary education."

The Mediterranean area undergoes different climatic influences and is known to be a climatic change hotspot by the IPCC. Indeed the climate change and sea level evolution are important there. It is also an ancient anthropised area where the actual population growth in the coastal area is important. High human densities imply high issues: touristic, economic, heritage, natural etc. Consequences on that area, natural and directly or indirectly anthropogenic ask new problematic. This symposium offers to consider on three of them:

  • Observed climatic evolution and simulation of future climate
  • Environmental changes in the Mediterranean: consequences, adaptation and vulnerability
  • The "natural" risks and the resilience of Mediterranean littoral urbanized area

Logo FuturearthThe animation of the secretariat of Future Earth has been awarded to an international consortium of France, the USA, Japan, Canada and Sweden. According to Michel Jarraud (WMO) as a consortium "strengthen the program's ability to build bridges between the communities of researchers and practitioners internationally." For France, ANR, alongside the Ministry of National Education, Higher Education and Research and Allenvi alliance, is an integral part of the secretariat.
