A report from Prince Charles' International Sustainability Unit has found that we are still some way from realising the full potential of tropical forests in stabilising global climate, agricultural yields, ecosystem services and local livelihoods. The report, Tropical Forests: A Review, argues that forests have such incredible potential because of their dual role as carbon sinks. Less deforestation means less carbon is released and as the forest continues to grow, more carbon is locked in to the biomass. The report also highlights the importance of tropical forests to regional and global rainfall cycles. This is particularly relevant for Brazil where a severe drought has impacted cities and major agricultural areas. Modelling has shown that deforestation in the Amazon and Congo Basin could affect rainfall patterns across Europe and North America. The report urges forests be prioritised as a significant solution as we approach binding international agreements on climate change.

A recent study has revealed how recovering forests manipulate the process of nitrogen fixation to ‘heal’ themselves. Forests recovering from agricultural land use demonstrated exceptionally high rates of biomass accumulation, indicating very high rates of nitrogen demand. The results from the study indicate that nitrogen-fixing trees should be used preferentially in reforestation projects.

The European Space Agency has given the go ahead to develop a satellite which use a radar system to “weigh” forests. The primary mission is to calculate the amount of carbon stored in the world’s forests. It will also monitor any changes in forest cover over the course of its five-year mission which is expected to launch in 2020. It is hoped that the data gathered will provide a basis for agreements under REDD+.

Representatives of NGOs and government agencies from Indonesia, Brazil, Mexico and Peru took part in a special technical training session on monitoring deforestation, forest degradation and biomass organised by the Governors' Climate and Forests Task Force (GCF). The week-long training aims to improve the measurement, reporting and verification (MRV) systems which are an integral part of REDD+.
