KUALA LUMPUR (Thomson Reuters Foundation) - Existing stands of mangroves may not survive beyond 2050 if sea level rise continues at current rates, scientists warned on Friday, urging a rethink on the conservation of the trees, which serve as vital coastline defences.

A team of international researchers found that mangroves will stop growing if sea levels rise by an average of 6mm per year, compared with 4mm currently.

But they are being destroyed at rates three to five times higher than the average for forests, and more than a quarter of the world’s mangroves have already disappeared, according to the United Nations.

When sea-level rise exceeded 6 millimetres per year - which is estimated to happen if emissions remain high up to 2050 - the researchers found that mangroves were likely to grow too slowly to keep sufficiently above the waves.
