Café MTD 2018

Le CAFE-MTD est de type plutôt informel, avec une durée de présentation assez courte pour permettre aux membres de l’UMR d’y assister sans que cela soit trop chronophage (une ou deux présentations d’une durée totale de 20 à 30 minutes suivie(s) d’une discussion).
Il s’agit de mettre en place un starter de communication pour améliorer les échanges scientifiques et techniques, et ainsi servir de support à un fonctionnement transversal entre les équipes.
Le jour retenu est le mardi de 11h30 à 12h30 (voir plus si les échanges sont fructueux) afin de permettre à tous de participer (pas d'interférence avec les heures de repas de ceux qui mangent tôt).  

Jeu 14 Oct

Edson Luis Bolfe

Jeudi 14 Octobre à 11h, Edson Luis Bolfe (EMBRAPA, Bresil) viendra nous faire une présentation dans le cadre des cafes MTD. 
Il nous présentera le travail réalisé dans le cadre d'une plate forme digitale "Aliments et Territoires au Bresil", en partenariat notamment avec Denis Sautier (CIRAD, UMR Innovation).

Titre de la présentation : Comment concevoir et mettre au service de la recherche et de ses usagers (consommateurs, entreprises, groupements de producteurs..) un outil digital de représentation, valorisation et mise en relation sur un sujet nouveau : les relations entre Aliments et Territoires ?

Context :

The future of sustainable rural and agricultural livelihoods relies on the combination and connection of different resource-based products, processes and services.
European countries, such as France, have already developed strategies to value traditional differentiated foods, regional and typical products, and geographical indications associated as an important source of income and rural development in many areas (Sautier et al., 2015).

In Brazil, the concept of multifunctionality has associate the agri-food and landscape planning in the elaboration of new public policy of rural development.The country's cultural identity, resulting from the miscegenation of indigenous, African, European and Asian heritage, has translated into clothing, religious manifestations, and the country's cuisine.
In addition, national biomes host about 20% of the world's biodiversity. Such factors, alongside historical and territorial occupation processes, have made Brazil a complex, dynamic country with great wealth of regional agri-food products.Consumers' protagonism through digital platforms has further increased the value of safe foods with traceability.

Studies have indicated that the main world food trends by 2020 are: Sensoriality and Pleasure, Healthiness and Wellness, Convenience and Practicality, Reliability and Quality, Sustainability and Ethics (Brasil Food Trends 2020).
Factors behind this demand, such as growth and aging population, increased purchasing power, reduced number of children per family, and participation of women in the labor market, have intensified this process. Hence there is increasing value in differentiated agri-food products in gastronomy and regional cuisine, especially due to the combinations brought forth by socio-biodiversity which compose a mosaic of Brazilian flavors and know-how. In 2016, the National Calendar of Events recorded 880 events, of which over 100 aimed at gastronomic appreciation (Sebrae, 2017).

It is worth highlighting the Northeast region, where their gastronomy has become an attraction as rich and important as beaches, historical cities, and cultural manifestations. Embrapa and partners have developed studies and activities on the national aspects of agri-food.
However, access to information on the diversity of responsible and sustainable agri-food products is limited in the country.Besides, most of the information available is segmented and there is a gap in the communication between the farmers and consumers who wish to consume such differentiated products.

There is a growing need for coordinated action through the organization of agri-food initiatives and their availability for society through digital platforms.
This project aims at developing and publishing a database on the production and consumption of differentiated agri-food products, to be organized into a digital platform that can connect farmers to consumers, and thus create a map of opportunities on Brazilian agri-food territories.In order to reach the goal of developing the Digital Platform, the project will be divided into three stages, which involves liaison between Embrapa's Secretariat of Intelligence and Strategic Relations, Embrapa Agricultural Informatics, SEBRAE (Brazilian Micro and Small Business Support Service) and CIRAD - UMR Innovation in France.

Title : An Approximation to Understand Urban Segregation. Merging Bigdata Analysis into the Time Geography Analysis framework in Chile

Abstract: While segregation is usually evaluated at the residential level, the recent influx of large streams of data describing urbanites’ movement across the city allows to generate detailed descriptions of spatio-temporal segregation patterns across the activity space of individuals. For instance, segregation across the activity space is usually thought to be lower compared to residential segregation given the importance of social complementarity, among other factors, shaping the economies of cities. However, these new dynamic approaches to segregation convey important methodological challenges.

I here propose a methodological framework to investigate segregation during working hours. Our approach combines three well-known mathematical tools: community detection algorithms, segregation metrics, and random walk analysis. Using Santiago (Chile) as a model system, I build a detailed home-work commuting network from a large dataset of mobile phone pings and spatially partitioned the city into several communities to evaluate the probability that two persons at their work location will come from the same community. 

While these findings highlights the benefit of developing new approaches to understand dynamic processes in the urban environment, it shows a specific example in which the exposure dimension of segregation is successfully studied using the growingly available streams of highly detailed anonymized mobile phone registries.

Bio: I graduated in Ecology at the University of New Mexico, USA in 2007. After a brief post-doctorate in the Department of Computer Science at UNM , I joined in 2008 as an academic at the Faculty of Forestry and Natural Resources of the Austral University of Chile in Valdivia. Between 2010 and 2012 I did a postdoc at the Center for Non Linear Studies at Los Alamos National Laboratory, USA. My interests and research are related to describe and explain dynamics of Complex Systems in ecology and urban systems. Among the latter, understand the relationship between diversity and sustainability to contribute to the development of urban policies that consider the complexity of social and environmental systems. For this, I focus my work on the use of massive data (Big Data) and Ecoinformatics as a multidisciplinary analysis tool.
