This ODA eligibility database presents examples of ODA and non-ODA eligible projects. The examples are meant to illustrate the application of the eligibility rules agreed by the DAC, see the Statistical Reporting Directives. They will facilitate the assessment of the eligibility of similar cases in future. The tool allows searching by different filters, e.g. sector or theme, or eligibility. Initially, the database covers all the cases presented in the ODA casebook on conflict, peace and security activities agreed by the DAC in 2017, but additional examples will be added in future.
