改变土地利用和碳储存和固存的管理做法正在成为应对气候变化和减轻贫困的全球努力的组成部分。然而，知识和证据的差距仍然很大。本文分析了在理解土壤和地上生物量碳储量方面最紧迫的不足，以及与碳封存项目相关的社会和经济挑战。我们将重点放在撒哈拉以南非洲的半干旱和干燥半湿润系统上，这些系统居住着世界上许多穷人，我们确定了需要解决的重要跨学科机遇和挑战，以便通过气候融资流和碳友好型土地管理带来的附带生态系统服务效益，使穷人从碳储存中受益。我们强调，从地方到区域的跨尺度多方利益相关者合作是必要的，以确保科学进步能够为政策和实践提供信息，从而实现碳排放、生态系统服务和扶贫效益。
Changes in land use and management practices to store and sequester carbon are becoming integral to global efforts that both address climate change and alleviate poverty. Knowledge and evidence gaps nevertheless abound. This paper analyses the most pressing deficiencies in understanding carbon storage in both soils and above ground biomass and the related social and economic challenges associated with carbon sequestration projects. Focusing on the semi-arid and dry sub-humid systems of sub-Saharan Africa which are inhabited by many of the world's poor, we identify important interdisciplinary opportunities and challenges that need to be addressed, in order for the poor to benefit from carbon storage, through both climate finance streams and the collateral ecosystem service benefits delivered by carbon-friendly land management. We emphasise that multi-stakeholder working across scales from the local to the regional is necessary to ensure that scientific advances can inform policy and practice to deliver carbon, ecosystem service and poverty alleviation benefits.
