ReCLim-Switch Working Group

Article A new recruit in the ReCLim-Switch project!

Noémie Ehstand, a postdoctoral researcher, has joined a group of Alsatian experts to study climate trends in Alsace-Vosges. A specialist in complex networks and stochastic modeling, she analyzes meteorological and hydrological data over several decades. Her work will help provide a reliable scientific reference for local authorities and the public.

CCAV-GES: Climate Change Alsace-Vosges, Group of Scientific Experts

Objective: To gather a group of local scientific experts on the issue of climate change at the regional scale Alsace-Vosges (city, mountain, plain...).

Creation: May 2022

 

Observation

Several scientific teams in Alsace are working and studying the signs, trends, observations and projections of climate change locally and regionally (temperature, rainfall patterns, effects on ecology, hydrology, etc.).
During this work, scientists sometimes use different inputs, different model outputs, data from different sources (Météo France, Vigie crue, Agence de l'eau, Aprona, DRIAS, IPCC, SAFRAN...), with different methodologies and processing etc...
Consequently, the results may show or reflect heterogeneities or variability that could/should be interpreted.
Moreover, these researchers study and work on different sites (mountain, piedmont, plain, city) or at different scales (spatial/temporal).
Finally, there is a need on the part of communities, decision-makers, associations, and citizens to have the most reliable and coherent data possible, with a collective scientific endorsement and probably a vision at the regional scale.

Goals

To set up an expert group on climate within SWITCH whose objective will be to build and publish a regional synthesis on climate change for the last 50 or 100 years (depending on available data).

  • To provide institutions with a single/common local scientific reference and avoid different expertise and/or oversimplifications sometimes...
  • Coordinate and build a common message/information to be transmitted to elected officials/publics/decision makers/associations/citizens etc...
  • To produce and create common supports (scientific + for all public), in particular via the support of the Garden of Sciences and collaborations with artists (designers, illustrators, actors...)

Justification: SWITCH has the skills to consider a joint scientific study of climate change on the scale of the Grand-East region, including mountains, foothills, plains and cities (not on projections, which is done elsewhere, but on observations and interpretations of recent decades).

Justifications

To have a study of this type would be:

  • scientifically interesting and relevant (not sure if it exists at this scale with a level of detail by "geo-hydro-morphological zone" in this context of global change. What variability of change and diversity of responses at the regional scale?  Using common climate indicators and signal processing tools;
  • socially very useful and relevant for decision makers, institutions, associations, but also teachers, students, the public etc. ;
  • ethically rich that the local scientific community speaks with one voice;
  • would also allow a better visibility for SWITCH.

Study area

  •     Mountain
  •     Piedmont
  •     Plain
  •     City


Ecosystems

  •     Forestry
  •     Vineyards
  •     Crops/pastures
  •     Urban - peri-urban centers

Partners / ressources

  • Research laboratory (SWITCH)
  • Météo-France, DRIAS
  • INRAE
  • Water Agency
  • Vigie Crue, DREAL
  • Eurometropole of Strasbourg (rain gauge network)
  • Ski resorts
  • Aero club/airfield
  • Schools/High Schools
  • Agricultural/viticultural areas
  • ONF/RENECOFOR
  • Region, CEA, Massif
  • Niv-Oses Association / APRONA
  • Natural Parks
  • Chamber of Agriculture
  • RENECOFOR network (ONF)...

Means

  •     Data collection, verification, homogenization, processing and synthesis
  •     CDI of researcher (post doc) on 24 months.
  •     We have developed various methodologies that we could share. A partnership with Météo-France seems natural.

The data collection will include structures with measurements (airports, airfields, ski resorts, agricultural sites, vineyards, schools, possibly public, others to define ....).

We could look for a financing together with several institutional co-financing (EMS, region, department, chamber of agriculture, ONF, météo-France, water agency, DREAL, OFB, AERM, regional parks etc.).

Track: AAP Region (post doc or young researcher) - IDEX UNISTRA - in co-financing?
