Study shows that 92.2 percent of tree cover loss in the Democratic Republic of Congo (DRC) and 48.2 percent in the Republic of Congo (ROC) is linked to small-scale shifting cultivation. Global Land Analysis and Discovery (GLAD) and World Resources Institute’s Congo team mapped the rural complex of DRC and ROC, with forest fragmentation to differentiate between the rural complex, fragmented forest and undisturbed forest. The DRC and ROC rural complex maps together enable better understanding which loss is caused by shifting cultivation cycling back to previously farmed areas, and which shows new deforestation, degradation or fragmentation.

A group of scientists questioned whether sustainable forest management (SFM) is an effective way as commonly believed to protect tropical forests and the habitat and carbon reserves. They published a study in the journal Land Use Policy arguing that SFM may not actually lead to less deforestation based on the their analysis of timber concessions in the Central African nation of the Republic of Congo. According to their research, timber concessions operating under forest management plans (FMPs) showed higher rates of deforestation than concessions without them. The research was criticized by some scientists as overly simplistic. One of the authors was hesitant to extend the findings beyond the borders of the Republic of Congo.

Rivers create species. For animals incapable of swimming through or flying over them--like most primates--large rivers can quickly become insurmountable barriers. One of the most famous examples of this evolutionary phenomenon is chimpanzees and bonobos, which are only separated by the Congo River. Now, scientists have discovered a new primate that also appears to follow this rule, blocked off from his cousins by a confluence of rivers in the Peruvian Amazon.

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.
