A new study published on the journal Proceedings of the National Academy of Sciences states that the role of agriculture in the destruction of mangrove forests in South-East Asia has been underestimated. The study is based on a 12-year assessment conducted between 2000 and 2012, which found that in South-East Asia mangroves were being lost at an average rate of 0.18%. Rice and palm oil plantations contributed nearly 40% to the lost. The author is calling for action as mangrove habitats in South-East Asia are highly biodiverse and are vital to the livelihood or millions of people.

A study recently published in Forest Ecology and Management examines the carbon stock value of forests in Guyana, finding dramatic differences between different kinds of cover and land-use types. Tropical forests are among the most valuable in terms of carbon stocks. Globally, tropical forests sequester about 2.4 billion metric tons, according to a study published in Proceedings of the National Academy of Sciences in 2011. The new research found that carbon values differ according to forest type and usage pattern; for instance, carbon values from undisturbed forests cannot be applied in inhabited community lands.
