In reaching their estimate, the researchers took into account major investments by both the public and private sectors in a wide range of projects. Examples include the funding of small-scale renewable energy projects in Uganda by the United Kingdom, Germany, Norway, and the European Union, as well as the African Risk Capacity – supported by the UK and Germany – which offers insurance to governments against drought and other natural disasters.
在计算这一数字时，研究者考虑了各种项目的公共和私人部门重大投资。其中的例子包括英国、德国、挪威和欧盟为乌干达提供的小规模可再生能源项目融资，以及英国和德国支持的非洲风险能力（African Risk Capacity）项目。后者为政府提供抵御干旱和其他自然灾害的保险。
