Communities living alongside the world's tropical forests can estimate an area's carbon stocks as effectively as hi-tech systems, according to findings published in the journal Ecology and Society. The study found that community members in four South-East Asian countries using sticks and ropes were able to gather the same results as satellites. The research team aim to convince policy makers of the vital role local communities can play under the UN’s Redd+ programme which aims to curb GHG emissions from deforestation and land-use change.
