The effects of gold mining in rivers in French Guiana

A study conducted in the French Guiana basin where artisanal gold mining in occurs has shown there is mercury in the environment from these activities. It is even found in the piscivorous fish and indigenous communities that eat food from the rivers affected. These are important and innovative...

Amazon groundwater quantified at last!

As the Amazon basin is difficult to access, the condition of its water table remained virtually unknown. The mystery was solved thanks to an assessment made by an international team linked to several IRD units and led by LEGOS researchers. This result is all the more interesting in that access to...

The Maroni River threatened by gold mines

How have the environmental changes that have occurred in recent decades in French Guiana, including gold extraction in the hinterland, affected the Maroni River? A team involving IRD researchers analysed changes in sediment flows in this water course since 2000. Their findings are alarming.

Effectiveness of marine reserves compromised by proximity to humans

The environmental benefits of marine reserves located near human populations are limited. This was demonstrated by researchers from the University of Montpellier, IRD and the University of New Caledonia, in conjunction with CNRS, as they studied 1,800 coral reefs, 106 of which were located in 20...
Large-scale hydroelectric dams on Andean rivers disrupt river connectivity to the Amazon.

Andean dams versus Amazonian biodiversity

A recent scientific study warns of the multiplication of large-scale hydroelectric dams on the Andean tributaries of the Amazon. These installations break up watercourses and pose a threat to the biodiversity and hydrological regime of the entire basin.
