Despite plans by the Madagascan government to expand its network of marine protected areas (MPAs), the country’s coral reefs remain under threat from local pressures such as overfishing, and global threats such as climate change. However, surveys by the World Conservation Society found the reefs around islands near Nosy Be, off Madagascar’s northwest coast, to be amongst the healthiest anywhere in the Western Indian Ocean. They found live coral cover to have increased in recent years, and fish biomass to be at carrying capacity.

The larger island of Nosy Be is home to a sizeable human population and a bustling tourism industry, likely placing the surrounding coral reefs under increased pressure.

 

Opwall will be working along a gradient of reef protection, from the strictly protected MPA at Nosy Tanihely to unmanaged reefs further along the coast. Our aims are to establish a technology-driven standardised reef monitoring program which can be combined with data sets from other key bioregions to explore patterns in coral reef functioning from present to future. Via this programme we will then collect long term reef health data across this human use gradient to compare the performance of reefs around Nosy Be to those of more remote locations nearby.
