Mangrove en Nouvelle-Calédonie

CO₂ capture capacity of the mangrove in Vietnam

The Air Liquide Foundation renews its support for the IRD with a view to developing a mangrove monitoring committee

Its high productivity level and its position where land meets sea make the mangrove an important ecosystem in the carbon cycle.

Develop an international mangroves monitoring committee

In 2010 and 2011, the Air Liquide Foundation supported an IRD research project concerning the capacity of New-Caledonian mangroves to store airborne CO₂.

In order for mangrove research to be more visible at global level, the IRD now wants to develop an international monitoring committee specifically dedicated to this ecosystem. Objective: track the evolution of mangroves in conjunction with climate change. And pay particular attention to the capacity of these mangroves to capture greenhouse gasses. Three sites have been selected to represent the climate zone in which they are found: in New Zealand (temperate zone), in New Caledonia (semi-arid zone), and in Vietnam (humid tropical zone).

The Vietnamese mangroves

The Vietnamese mangroves are extremely diverse, with over 60 species of mangrove trees spread over around 150,000 hectares. Site chosen for the research project: Can Gio. it covers a surface of 35,000 hectares to the north-east of the Mekong delta and is recognized as a UNESCO biosphere reserve.

This project concerns this mangrove's capacity to capture CO₂ and aims to answer two questions:

  • What is the CO₂ flow rate from the sediments of the mangrove, of the river, and of the canopy?
  • What factors are responsible for variations in this flow?
This project differs from the previous one in New Caledonia because the teams also intend to measure carbon stocks in the biomass.

The results of these tests will be compared with those of the other mangroves being monitored. The Air Liquide Foundation support this project for 2 years and provide funds for the analysis equipments.

The Institut de Recherche pour le Développement (IRD)

The mission of the Institut de Recherche pour le Développement (IRD), a research organisation based in Marseilles, is to carry out research on the major issues affecting our world today: global warming, emerging illnesses, biodiversity, access to water, hunger in the world… and to contribute, through training, to bolstering the scientific community in the South of France. Researchers, engineers, technicians and local staff are at work in 50 countries and participate in many national and international programs.
