There is limited research providing quantitative estimates of adaptation costs across Africa. Adaptation costs in Africa have been estimated at USD 7-15 billion per year by 2020 , corresponding to USD 5-11 per capita per year. The African Development Bank estimates costs of near-term adaptation needs identified in the Intended NDCs  of African countries as USD 7.4 billion per year from 2020, recognising INDCs describe only a limited subset of adaptation needs . Many African countries, particularly Least Developed Countries , express a stronger demand for adaptation finance-a study of financial demands in INDCs for 16 African countries suggests a ratio around 2:1 for adaptation to mitigation finance with demand for Eritrea and Uganda approximately 80% for adaptation .
