Un enjeu important de la recherche sur les maladies transmissibles concerne l'estimation précise et localisée du risque épidémiologique dans les populations d'hôtes et de vecteurs concernées. Dans cette optique, la démarche de modélisation individu-centrée intègre l'hétérogénéité spatiale et individuelle pour simuler la dynamique...

Bubonic plague, a zoonotic infection that circulates in wild rodents but is transmissible from them to humans through the bites of infected fleas, is not merely of historical interest. It is widespread in the world today and a continuing threat (Stenseth et al. (2008). In the Pre-Balkhash autonomous focus (Kazakhstan, central Asia), the great...
This paper presents a dynamic modeling framework applied to the bubonic plague of the Highlands of Madagascar, which incorporates the heterogeneity of the structure of rodent populations, the main hosts, and their flea vectors. A coupling method is proposed between two modeling approaches, the one individual-based, with a multi-agent formalism,...
Short distribution channels in the food industry are currently a growing, multifaceted reality. They have become increasingly structured and their expansion is enjoying growing support from local authorities. This article identifies the real development potentials of these Territorial Food Systems in the Provence-Alpes-Côte d'Azur region,...
Individual-based or population-level simulation approaches are often employed alternatively in eco-epidemiological modeling. In this paper, we introduce an original coupling approach applied to bubonic plague zoonotic infection in the Pre-Balkhash focus (central Asia), with main host Rhombomys opimus (Rodentia: Gerbillidae) and vector its...
Short food supply chains are expanding as a multifaceted reality, becoming increasingly structured and supported by local authorities. Prior to consider the structuring of this sector, the purpose of this article is to identify the real development potentials of these Territorial Food Systems: we propose an integrated exploratory multivariate...
We present a model showing the evolution of an organization of agents who discuss democratically about good practices. This model feeds on a field work we did for about twelve years in France where we followed NPOs, called AMAPs, and observed their construction through time at the regional and national level. Most of the hypothesis we make here...
We present a model showing the evolution of an organization of agents who discuss democratically about good practices. This model feeds on a field study we did for a few years in France where we followed Non Profit Organizations, called AMAP (a french short food chain), and observed their construction through time at the regional and national...
This work addresses the spread of a disease within an urban system, defined as a network of interconnected cities. The first step consists of comparing two different approaches: a macroscopic one, based on a system of coupled Ordinary Differential Equations (ODE) Susceptible-Infected-Recovered (SIR) systems exploiting populations on nodes and...

A hybrid model coupling an aggregated equation-based model and an agent-based model is presented in this article. It is applied to the simulation of a disease spread in a city network. We focus here on the evaluation of our hybrid model by comparing it with a simple aggregated model. We progressively introduce heterogeneities ...

Dans cet article, nous nous intéressons à la diffusion de maladies dans un réseau. Nous comparons deux approches, l'une macroscopique (métapopulationnelle) et l'autre hybride, couplant des systèmes dynamiques de type EDO sur les nœuds et des agents sur les arêtes Nous reproduisons le même pic d'intensité de l'épidémie (Imax) avec ces deux...
Health geographics is a fast-developing research area. Subjects broached in scientific literature are most varied, ranging from vectorial diseases to access to healthcare, with a recent revival of themes such as the implication of health in the Smart City, or a predominantly individual-centered approach. Far beyond standard meta-analyses, the...
The world population is ageing. In France, this phenomenon is particularly pronounced with 19.6% of the population being over 65-year-old in 2018. While it has been recognized that urban form plays an important role in ensuring a sustainable future for urban areas, ageing dynamics are challenging the core concept of urban sustainability....
