Maxime Duphil
Maxime Duphil
(IRD - Noumea)

Maxime is ambassador student within the PACPATH project and PhD student at IRD in Noumea within the ENTROPIE laboratory on evaluation of the protective role of coastal ecosystems (reefs, seagrass beds and mangroves) in the reduction of the marine submersion hazard in New Caledonia. The focus is on both seasonal phenomena (e.g. swell) and extreme events (e.g. cyclones and tsunamis). This ecosystem service of protection will be approached according to an interdisciplinary approach between Human and Social Sciences (e.g. field surveys) and Earth Sciences (e.g. hydrodynamic modeling). The goal is to quantify and qualify the filtering effect of ecosystems on several sites in New Caledonia by looking at different hydrodynamic variables: water levels, waves and currents.

Lucie Gosset
Lucie Gosset
(IRD - Noumea)

Lucie Gosset is a student ambassador within the PACPATH project and PHD at IRD. Her research is part of the CLIPSSA program (Pacific Climate, Local Knowledge and Adaptation Strategies) which is a regional interdisciplinary program in the Pacific covering Wallis and Futuna, French Polynesia, New Caledonia and Vanuatu. In this program, atmospheric dynamics is at the center of the study of climate change. In articulation with the work of climatologists, Lucie’s research in anthropology will focus on New Caledonia and Vanuatu. The aim of her research is to understand to what extent local ecological knowledge produced to cope with environmental variability can be a resource on which public policies can rely to reduce the vulnerability of populations to climate change. To achieve her work, Lucie focuses on describing how people understand, live and cope with changes in climate conditions. She also analyzes the interactions between various types of knowledge (scientific, NGO, academic, etc.) concerning the characterization or management of environmental conditions and their effects on local ecological knowledge and the way they are transmitted.
