Intergovernmental Authority on Development

The Intergovernmental Authority on Development was established in 1996. It succeeded the earlier Intergovernmental Authority on Drought and Development (IGADD), a multinational body founded in 1986 by Djibouti, Ethiopia, Somalia, Sudan, Uganda and Kenya, with a focus on development and environmental control. IGADD's headquarters were later moved to Djibouti, following an agreement signed in January 1986 by the member states. Eritrea joined the organization in 1993, upon achieving independence. In April 1995, the Assembly of Heads of State and Government met in Addis Ababa, where they agreed to strengthen cooperation through the organization. This was followed with the signing of a Letter of Instrument to Amend the IGADD Charter / Agreement on 21 March 1996. The Revitalised IGAD, a new organizational structure, was eventually launched on 25 November 1996 in Djibouti. ==Member states==

The Secretariat assists member states in formulating regional projects in the priority areas, facilitates the coordination and harmonization of development policies, mobilizes resources to implement regional projects and programs approved by the council and reinforces national infrastructures necessary for implementing regional projects and policies. The current Executive Secretary is Workneh Gebeyehu of Ethiopia (since 29 November 2019). • The Council of Ministers is composed of the Ministers of Foreign Affairs and one other Minister designated by each member state.
