In five of the six countries (with the exception of India), the return of native forests was accompanied by a reduction in timber harvests and new farmland, thus creating a demand for imported wood and agricultural products.
"For every 100 acres of reforestation in these five countries, they imported the equivalent of 74 acres of forest products," said Meyfroidt, a postdoctoral researcher at Louvain and lead author of the study. "Taking into account their exports of agricultural products, the net balance amounted to 22 acres of land used in other countries."
During the past five years, the net land-use displacement increased to 52 acres of imported agricultural or forestry products for every 100 acres reforested, he added. That is, for every acre of reforested land, a half-acre was used elsewhere, including countries like Brazil and Indonesia, which together accounted for 61 percent of the all deforestation in the humid tropics between 2000 and 2005.
So if some government dictates reforesting of former forests and jungles more trees will get cut down in Brazil and Indonesia. We need cheap substitutes for wood. Unfortunately economic growth will increase buying power for wood products. So I expect even more deforestation as the world economy grows.
