To protect the coral at sea, fight deforestation!

A new study published in the June 4 issue of Nature Communications has found that forest protection will also work to protect submarine reefs, as this will limit the amount of substance. sediment poured into the sea.

The international team led by Macquarie University scientist Joseph Maina at Sydne, Australia, while conducting research in Madagascar, found that the coral reefs near the coast were suffering from low levels of depression. The area increases due to deforestation and the river flows to the sea.

This large amount of sediment is harmful to coral growth, the ecosystem is very fragile but it is home to many marine species, because it limits coral exposure to sunlight and makes reverse their growth.

Scientists have modeled the variation of the flow and sediment load of four rivers in Madagascar according to climate change and whether or not the forest is protected.

They found that, in 2009, climate change should have caused silt on rivers and the amount of sediment flowing into coral reefs, but in fact these materials still increased due to compensation. covering from sediments created by deforestation.

Since then, scientists have suggested that to protect corals, land use management will play a more important role than trying to limit climate change.

This study also shows that the amount of sediment flowing into the sea can be reduced from one-fifth to two-thirds if forests recover 10% -50%.
