The Intergovernmental Authority on Development (IGAD) superseded the Intergovernmental Authority on Drought and Development (IGADD) established in 1986 by the then drought afflicted six Eastern African countries of Djibouti, Ethiopia, Kenya, Somalia, Sudan and Uganda.
The State of Eritrea was admitted as the seventh member of the Authority at the 4th Summit of Heads of State and Government in Addis Ababa, September 1993.
IGRAC and IGAD
In 2014, IGRAC carried out a project on Managed Aquifer Recharge (MAR) in the transboundary Merti Aquifer, shared between Kenya and Somalia. This project was commissioned by the Inland Water Resources Management Programme of IGAD (IGAD-INWRMP).
