After a Ph.D. in population biology and ecology in the ThéMA laboratory (2017-2021), Paul Savary has been a post-doctoral fellow in the Department of Biology of Concordia University in Montreal (Canada) from 2022 to 2024, under two different fellowships.
He is starting a new position as an Assistant professor (Chaire de Professeur Junior) in ecology and spatial modelling at ThéMA. His research mainly focuses on species movements within spatial ecological networks. Lately, he has been using citizen science data to investigate biodiversity dynamics within urban ecosystems, a research line central to the research he will carry out at ThéMA in the coming years.
The so-called Chaires de Professeur Junior (CPJ) are dedicated to early-career researchers, offering them the opportunity to lead their own research team and participate in national, european, and international projects.

Thesis Abstract
As a result of climate change, heat waves are increasing and intensifying. At the same time, more and more people live in cities where urban heat islands (UHI) are developing. Heat waves and combined UHI contribute to the emergence of health risks backed by thermal stress. France "discovered" this risk in 2003. Building on this experience, prevention policies have developed. But prevention is not enough and must be combined with policies to adapt to climate change. Town planning is to be re-examined. Choice of materials, colors, urban forms are to work. But, in terms of refreshment, the greatest potential lies in the greening of cities. The plants, by evapotranspiration, refresh the ambient air. Creating green spaces is favoring a cooling effect often called "Urban Freshness Island" (UFI). Faced with these challenges, urban planners are increasingly demanding tools to know where and how to plant vegetation at the metropolitan scale. It is therefore a question of having a systemic approach where one models the climate of the city by integrating the vegetated spaces and the scenarisation methods based on local needs. This approach is based on numerical modeling. With the SURFEX platform coupled to the MesoNH climate model developed by Météo France, we are first going to test the sensitivity of the model to a better description of urban vegetation. This first step assess the reference simulation. The application relates to Dijon Métropole which has a network of 72 temperature sensors essential for the validation of the control simulation of the model. The heat waves of 2020 demonstrated a drought that worsened during the summer that is an ideal study case to chel the impact of vegetation during heat waves at the city scale. The co-construction of green scenarios takes places into an european project called RESPONSE H2020 with Dijon's local urban planners. After this work step, we suggest integrated methods for calculating fine-scale revegetation scenarios. These scenarios can then be tested and compared to the reference simulation. Particular attention is paid to UTCI and ICU values which make it possible to measure the impact of adding vegetation on temperatures at street scale.

Julie Gravier studies long-term settlement dynamics. Two questions drive her research: why and how do settlement systems persist in the same places for extremely long periods of time? What is the political role of individuals and groups in perpetuating the social functioning and spatial organization of settlement systems? Her aim is to understand the ways in which societies inhabit the world, taking into account very long-term dynamics and the temporal shifts in certain decisions on other processes. To achieve this, she studies a wide range of chronological and cultural cases, mainly on local to macro-regional scales.
After defending a Ph.D. dissertation entitled A city within its systems of cities over two thousand years: the case study of Noyon as an approach proposal at the University of Paris 1 - Panthéon-Sorbonne, Julie Gravier had completed several postdoctoral fellowships, most recently at the School of Advanced Studies in the Social Sciences (EHESS), and obtained the external competition for researchers at CNRS in 2024.

The book was published in July 2024 by Wiley-ISTE.
The aim of this book is to provide an overview of the concepts and methods used in fractal analysis and modeling in order to study the spatial distribution of human settlements. The main concepts and mathematical tools are reviewed, and emphasis is placed on the practical benefits of their application and the pitfalls to be avoided when using them.
The first part of the book is devoted to the basic concepts and geometric reference figures required for fractal analysis in human geography. In the second part, the principles of four major families of analysis methods are explained in detail: fractal analyses of point sequences, fractal methods for morphological delineation of urban agglomerations, multifractal analyses and cross scale signatures. The third part of the book is devoted to applications of fractal geometry in urban and regional planning.

Manon Kohler organizes this workshop with two invited speakers: Mathias Jehling and Casper Kleiner from the Leibniz Institute of Ecological Urban and Regional Development (Dresden, Germany).

Mathias Jehling is senior researcher at Leibniz Institute of Ecological Urban and Regional Development (IOER) in Dresden, Germany, where he leads the research group on “Urban Structure and Policy”. His focus is on geographic information in the planning context. He works and teaches (TU Dresden) on urban form and institutionalist approaches to planning and land policies.
Caspar Kleiner is a researcher at Leibniz Institute of Ecological Urban and Regional Development (IOER) and PhD-candidate at TU Dortmund University. With a background in architecture and urbanism he focusses on the interlinkages of land policy and urban form.
Abstract : Urban form is a key element for the objective of sustainable development of cities and regions. Especially in Europe, policy makers have started implementing land policies aiming for characteristics of urban form like density, accessibility, lower land-take rates or more diverse building types than single family houses to achieve this goal. While general trends towards lower rates of land-take are measurable, general urbanisation trends are still defined by patterns of new land-take, predominance of single-family houses and urban sprawl. The question arises, whether land policies actually have an impact on urban form and whether different land policy settings lead to different patterns in urban form. Therefore, this contribution explores the research question “What patterns of urban from emerge in different land policy systems?”. The broad availability of geo-data analysis approaches and data from harmonised national data sources allow for large scale analysis of urban form patterns. To compare these patterns of urban form in different land policy systems, a setting is required that limits other factors on urban form like demographic, economic or cultural development from land polices. Here, the French-German border-region serves as a suitable study area. A geospatial model is set up containing building footprint, parcel and street network information from national data-sources. We derive urban development projects of different periods which are then assessed for their characteristics of urban form, i.e. compactness, density, building types, and accessibilities. The concept sustainability is used as a lens through which these characteristics are assessed. The analysis allows a closer look into the patterns of urban form emerging in the two land policy settings and lays the basis for further assessing land policy impacts in the two different policy systems.
Keywords : comparative analysis, urban form, morphometrics, land policy, sustainability
