根据全球人口预测，非洲将出现最大的人口增长，非洲大陆仍有大部分可用于确保粮食安全的未开垦土地。与此同时，由于持续的土地使用变化、工业化和运输等原因，非洲将成为全球温室气体的主要排放国，预计温室气体排放量将增加。然而，由于非洲大陆幅员辽阔，多样性很大，因此缺乏对整个非洲大陆的观测，因此对温室气体排放源和汇及其变异性的独特了解在很大程度上仍然是未知的。因此，比以往任何时候都更需要一个环境研究基础设施，就像其他地区一样。在这里，我们提出了一个设计研究的结果，制定了在非洲建立这样一个环境研究基础设施的蓝图。该蓝图包括现有观测的清单，位置的空间分解，这将有助于减少非洲和全球气候强迫的不确定性，以及未来30年此类努力的总估计成本约为5.5亿欧元。我们进一步强调发展电子基础设施的重要性，能力发展的必要性，以及所有利益攸关方的参与，以确保非洲的自主权。
Global population projections foresee the biggest increase to occur in Africa with most of the available uncultivated land to ensure food security remaining on the continent. Simultaneously, greenhouse gas emissions are expected to rise due to ongoing land use change, industrialisation, and transport amongst other reasons with Africa becoming a major emitter of greenhouse gases globally. However, distinct knowledge on greenhouse gas emissions sources and sinks as well as their variability remains largely unknown caused by its vast size and diversity and an according lack of observations across the continent. Thus, an environmental research infrastructure—as being setup in other regions—is more needed than ever. Here, we present the results of a design study that developed a blueprint for establishing such an environmental research infrastructure in Africa. The blueprint comprises an inventory of already existing observations, the spatial disaggregation of locations that will enable to reduce the uncertainty in climate forcing’s in Africa and globally as well as an overall estimated cost for such an endeavour of about 550 M€ over the next 30 years. We further highlight the importance of the development of an e-infrastructure, the necessity for capacity development and the inclusion of all stakeholders to ensure African ownership.
