Restoration of degraded land can create vast bioenergy crop potential, without constraining food crops or other land use options. This presents an important opportunity for African countries to develop modern, sustainable bioenergy from rapidly growing wood crops at the same time as pursuing ambitious forest landscape restoration initiatives. This study from the International Renewable Energy Agency (IRENA) presents a methodology to estimate the sustainable energy potential from land restoration in line with the Bonn Challenge, particularly as it relates to African countries. The Bonn Challenge is a global effort to bring 150 million hectares of the world’s deforested and degraded land into restoration by 2020, and 350 million hectares by 2030.
