Research Themes

Animators: Michel Bertignac and Marie Nevoux

Assessing the state, understanding and projecting the dynamics of ecosystems subjected to multiple pressures, both abiotic, such as those associated with climate change, resource exploitation or habitat alterations, or biotic, such as those associated with biological invasions, requires integrating all ecosystem compartments and their interactions, as well as the dynamics of uses and anthropogenic pressures, in a resolutely holistic approach. To achieve this integration, the research activities carried out within the framework of theme 2 are divided into three sub-themes.

Sub-theme 2.1 (Uses in socio-ecosystems, dynamics of fisheries) is interested in the analysis of the uses, their impacts on the environment but also their responses to the dynamics of the ecosystems and to management measures.

Sub-theme 2.2 (Multiple pressures, impacts and assessment of the ecological status) aims at studying and quantifying the cumulative effects and multiple pressures and to better understand their dynamics and their effects on the functions and evolution of the ecosystems.
This work on the integrated assessment of ecosystems and human activities is also intended to feed the construction of decision-making tools, in interaction with societal demand and in support of public policies, which are carried out in sub-theme 2.3 (Decision-making support for the conservation, restoration and sustainable management of ecosystems).
