LIA-D3E - Taiwan

Scientific Meeting in Montpellier (France)
On 6th of July 2016, a group of researchers involved in the new LIA-D3E (Laboratoire International Associé - From Deep Earth to Extreme Events) in Earth Sciences between France and Taiwan gathered in Géosciences Montpellier, University of Montpellier, France. The day was actually divided into a Scientific and a Steering Committee meetings. The Scientific Meeting gathered the researchers responsible for the three main axes of the scientific project (1) Extreme Events, (2) Mountain Building, and (3) Deep Earth Interior.

LIA-D3E in a few words

The LIA-D3E gathers French and Taiwanese scientists who study how the different components of the Earth’s system (atmosphere, hydrosphere, lithosphere) interact in response to various internal (Tectonics) and external (Climate) forcing.

Even if our planet has always been changing, and will continue to do so, it seems that there is a major difference between the changes that are occurring now and those that occurred in the past. The "skin" of the Earth is apparently changing faster than in the geological past and most of the involved scientists agree on the fact that this accelerated pace of change is due to human activity. However, to apprehend to what extent human-induced changes are disrupting the present-day environment, we need to understand how the environment was changing on different time scales and before anthropogenic activities. This is a critical issue to be able to distinguish short-term, human-induced trends from longer-term, natural trends. In recent years, a new integrative view of Earth science consists in considering our planet as a whole, that is as a dynamic system whose components are all in close interactions.

In particular, there is a growing interest for the study of the interaction processes between the lithosphere on the one hand, the ocean, the atmosphere and the biosphere on the other hand. Within the French-Taiwan collaboration in Earth science, most of the involved researchers place their research at the heart of this dynamics and study the complex processes and natural phenomena that lie at the interface between the lithosphere and the other fluid envelopes. The study of the Earth system necessarily involves a synergy developed within a trans-disciplinary context between observations, theory and modeling. The LIA-D3E involves specialists of the lithosphere and deep Earth, specialists of the continental surface and interfaces, as well as specialists of the atmosphere. We hope that this scientific bi-national and trans-disciplinary association will allow major breakthroughs in understanding some of the major scientific challenges that remain to be elucidated.
