The E.U. Timber Regulation came into effect in 2013, near the end of the study period. It requires “due diligence” from importers to verify that timber they’re bringing into E.U. markets isn’t illegally harvested, particularly when it comes from “high-risk” countries. Fuller said those restrictions could be a “plausible” factor behind why China had become such a large export market.
The researchers published their findings in the journal Area on June 27th.
To determine the effect that this demand had on forests, the team also looked at satellite data tracking annual rates of tree cover loss in each of the countries.
The Democratic Republic of Congo, with the region’s largest bank of forest, didn’t export a lot of wood to China during the study period. Fuller said the DRC’s lack of roads made getting timber out of the forests difficult and expensive, and subsistence farming remains the main cause of deforestation there.
But a statistical model revealed a correlation between the levels of timber exports to China and the rate of tree cover loss in the Republic of Congo, Cameroon, Central African Republic, and Gabon. What’s more, those export figures did a better job of explaining the countries’ rates of tree cover loss than other factors such as rural population growth, palm oil production, and the existence of logging roads.
The analysis also turned up a marked shift in where that wood was coming from. Until 2009, Gabon was China’s major supplier, responsible for 60 percent of the wood exported from the Congo Basin to China. But a 2010 ban on the export of unprocessed logs in Gabon, aimed at building up its own wood processing sector, slashed that figure to 30 percent by 2015.
Fuller and his colleagues calculated that the Republic of Congo and Cameroon, where timber regulations aren’t as strict, have made up for the shortfall, and by 2015, together they accounted for half of China’s timber supply from the region.
