Forthis reason, we use the surface area of reforested and restored land to measure degree of implementation in Iceland (see below), and apply that to total mitigation potential measured in abated greenhouse gas emissions in the target countries. This constitutes 1.4% (i.3%-i.6%) of the 3,000-3,600 kha estimated to have been covered by woodland before settlement, as stated in the previous section. We therefore take this percentage range to be the degree of implementation for reforestation in Iceland. If we take revegetation of the estimated 40% of Iceland's surface (41,200 kha) affected by wind erosion (see previous section) to represent the technical potential for restoration, the currently revegetated area represents a 0.65% degree of implementation.
