Sail for mangroves in Gambia2024-01-10T11:23:54+01:00


Second year of expedition on the Gambia River to study the mangrove ecosystem

Onboard missions

With the Fleur de Passion sailboat, a traditional 33-metre ketch flying the Swiss flag, Pacifique’s mission is to explore the Gambia River along the following lines:

  • Academic cooperation between the University of Geneva (UNIGE), Switzerland, Swansea University, UK, and the GREAT Institute, The Gambia, to train new generations of Gambian and Swiss students in coastal and maritime scientific research.
  • To study the Gambian mangrove, a little-studied ecosystem, by gathering scientific information, in particular on its state of health, through water and sediment sampling campaigns using measuring equipment on board the Fleur de Passion sailboat.
  • Improve overall understanding of the role of mangroves in the context of global warming by analyzing greenhouse gas emissions, notably CO2 and methane, captured and originating from mangroves.
  • Encourage artists to come on board and tell the story of the expedition in a sensitive way. The drawings and texts are published in the “Sillages” publication. This mission is an important part of Pacifique’s awareness-raising missions.”

A multidisciplinary expedition

Since 2015, Pacifique has been encouraging Swiss and local artists to come aboard its sailing ships.

Through “Sillages”, a poetic and drawn publication published annually for 5 years, Pacifique aims to raise readers’ awareness of contemporary environmental issues through the prism of art.

In 2023, during the Gambia expedition, two artists – Marfa Indoukaeva and Matthieu Berthod – sketched and drew Gambian landscapes. The works can be seen in number 3 of “Sillages”, published on December 1, 2023.

Event at UNIGE

Following the first year of the expedition, a film and round-table discussion were held on November 6, 2023 at the University of Geneva. The film retraces the first year of the Mauritius expedition.

Produced and edited by Pascal Baumgartner.


The mission runs from January 8 to 21, 2024 on the Gambia River


  • Water/soil/air sampling campaign
  • Launch and debriefing conference at the end of the mission in Banjul
  • Raising awareness through drawings in the “Sillages” publication

The project is being carried out in partnership with the University of Geneva (UNIGE), the GREAT Institute Gambia, and Swansea University in United Kingdom.
During the mission, some 15 Gambian students will be taking part in the expedition.

Project leaders

The “Sailing for Mangroves” project is a new mission emerging from the partnership between Pacifique and the University of Geneva.

This mission directly echoes the “Arctic Change” and “Winds of change” programs, innovative pilot projects for monitoring greenhouse gases at the ocean surface developed by Dr. Daphne Donis and Prof. Daniel F. McGinnis of the F.-A. Forel Department of Environmental and Water Sciences (DEFSE) at the Faculty of Sciences, University of Geneva.
They have been partners of the foundation since 2015.
