Recently, the Forestry Minstry issued Ministerial Decree No. 633/2014, which determines Indonesia’s forest reference emission level (FREL). According to the decree, the reference emission level to...
Rainforest protection should focus on boosting resilience to climate change
Efforts to protect tropical forests under the proposed reducing emissions from deforestation and degradation (REDD) program should focus on conserving large-scale moisture gradients and areas that provide connectivity between major ecozones in order to reduce the impacts of climate change on ecosystem function and the compounding effects of deforestation, argue scientists writing in the journal Nature.
Noting that drying trends in the tropics are exacerbating fire and facilitating the destruction of forests, Jedediah Brodie of the University of Montana, Eric Post of Penn State University, and William Laurance of Australia's James Cook University say such measures could safeguard biodiversity by creating migration corridors for plants and wildlife and protecting water cycles dependent on forests. Some research suggests forests act as giant moisture pumps that help deliver precipitation to regions that would otherwise be much drier.
The authors say that while REDD is well-intentioned, it currently lacks "explicit mechanisms for increasing forest resilience". REDD policy should focus on protecting these key forest areas as well as "[reducing] or [halting] agricultural expansion in areas of rapid deforestation, especially when such areas are also susceptible to drying, as in the Amazon’s arc of deforestation."
"Many tropical trees are resistant to modest temperature increases and even drought. But if these changes lead people to set more fires, rainforests could be devastated," said Brodie, the author's lead author, in a statement. "This effect may be vastly more harmful than the impacts of climate change alone.”
“On its own, climate change could stress tropical forests, but when you add in human-lit fires and increased logging, it’s like hitting them with a sledgehammer,” he continued. “Small, isolated parks won’t be big enough to withstand these pressures. If we’re going to protect tropical biodiversity in the long term, we need to think really, really big.”
Assessing illegal logging
Chatham House is assessing the scale and effectiveness of the response to illegal logging and the related trade around the world. Full details of this work, including analysis and data, will be available online soon.
