木材燃料在撒哈拉以南非洲国家的能源平衡中发挥着主导作用，许多地区存在或被认为存在木材燃料短缺。这卷书描述了绘制撒哈拉以南非洲各种植被和土地覆盖类型图的第一次尝试，并评估了木本生物量的不断增长的存量和可持续产量。这是能源部门管理援助方案（能源管理援助方案）为解决大多数非洲国家缺乏能源资源数据的问题而开展的一个项目的结果。这些信息对于计算能量平衡至关重要。然而，这项工作的有用性远远超出了能源充足的问题。对非洲生物资源的适当管理-希望这一工作将对此作出贡献-将有助于保持并也许提高非洲大陆的环境质量。此外，全世界森林覆盖的范围已被认为是预测全球气候变化的一个关键变量。这些考虑因素加在一起，使评估非洲现有木材资源成为一项及时的干预措施。这项研究包括：讨论植被和土地利用制图的气象卫星数据;描述土地覆盖类别分类和制图过程;木质生物量评估;生物量类别描述;最后，按生物量类别分列的区域摘要。
Woodfuels play a dominant role in energy balance of countries in Sub-Saharan Africa, and shortages of woodfuel exist, or are perceived to exist, in many areas. This volume describes a first attempt to map the varied vegetation and types of land cover in Sub-Saharan Africa and to assess the growing stock and sustainable yield of woody biomass. It is the result of a project undertaken by the Energy Sector Management Assistance Program (ESMAP) to address the lack of data on energy resources for most African countries. This information is essential for calculating energy balances. The work's usefulness, however, goes far beyond questions of energy sufficiency. Appropriate management of Africa's biological resources, to which it is hoped this work will contribute, will help maintain and perhaps enhance environmental quality on the continent. Moreover, the extent of worldwide forest cover has come to be recognized as a critical variable in predicting global climate change. Together these considerations make the assessment of existing wood resources in Africa a timely intervention. This study includes: a discussion on meteorological satellite data for vegetation and land use mapping; a description of the processes used in classifying and mapping land cover classes; a woody biomass assessment; a description of biomass classes; and finally, regional summaries by class of biomass.
