North Korea: Maplecroft, a UK-based risk consulting company, announced that deforestation in North Korea is the third worst in the world after Nigeria and Indonesia. Park Jong-hwa, a professor of environmental studies at Seoul National University, said that judging from NASA`s satellite images, 13,878 square kilometres or 11.3 percent of North Korean territory comprised deforested mountains. The Korea Forest Service of South Korea estimated that reforesting North Korea will require 4.9 billion trees.
On the other hand, South Korea made its territory green with trees thanks to a large-scale forestation drive in the 1960s and 70s. Impressed with this progress, the UN rated South Korea’s forestation as the only successful case after World War II.
