In our changing world, submitted to huge anthropic pressures, ecosystem protection needs new paradigms. Among them, ecological restoration is emerging, which aims at enhancing biodiversity and ecological services in response to human pressure. As usual in novel research areas, the information is dispersed, and there is a lack of synthesis of the data collected. The aim of my postdoctoral stay in the Instituto Pirenaico de Ecologia is to coordinate an international team/task for producing a critical meta-analysis on the real benefits provided by Ecological Restoration projects in terrestrial ecosystems according to the initial degradation and the type of restoration (biotic vs abiotic) implemented. I started this postdoctoral stay in November 2016. Step by step, and in order to avoid redundancy with recent meta-analyses, and based on the screening on > 2300 articles, my colleagues and I decided to focus this work on both the impact of the "initial degradation intensity" and the complexity of the restoration actions implemented on the recovery completeness of the ecosystem.
My research focuses on both Ecological restoration of terrestrial ecosystem functions and services, after degradation under anthropic pressure, and water “green” management. I first worked on how to use ecological engineering tools in order to treat in a green way waters contaminated by trace elements, as part of my PhD (Phytoremediation in Constructed wetlands of waters contaminated by Copper, University of Bordeaux - Biogeco laboratory, France). During this PhD I spent few months in Australia (Monash University, Melbourne), to refine my skills in urban wastewater treatment. I then kept working on the general topic of ecotoxicology though a postdoctoral position at BIOGECO (Bordeaux, France). This job consisted in providing innovative and sustainable tools for (phyto) managing contaminated soils (and waters) in the city of Bordeaux. In parallel, I worked on gentle remediation options aiming at rehabilitate and restore contaminated terrestrial ecosystems (polluted by trace elements, Hydrocarbons, etc.). At that time, I started studying research axis dealing with ecological restoration, whose aim is to bring back the ecosystems to their initial trajectory after anthropic pressures/degradations. I took advantage of my AgreenSkills position at the IPE (Jaca-Spain) for producing a meta-analysis dealing with this topic. I have currently a position in the Lyre, a research development of Suez Environment society, jointed to the university of Bordeaux.
