The Federal Ministries of Nigeria are Civil Service departments that are responsible for delivering various types of government service. Each ministry is headed by a Permanent Secretary who reports to a Minister in the Federal Cabinet. Some government functions are provided by Commissions or parastatals (government-owned corporations) that may be associated with a ministry or may be independent, also headed by Permanent Secretaries.
At times, ministries are amalgamated and at other times they are split. Thus Halima Tayo Alao was appointed Minister of Environment and Housing on 26 July 2007 by President Umaru Yar'Adua. After a cabinet reshuffle, in December 2008 Nduese Essien was appointed Minister of Environment and Hassan Muhammed Lawal was appointed Minister of Works and Housing. On 6 April 2010, Mohammed Daggash was appointed Minister of Works and Nduese Essien was appointed Minister of Lands, Housing & Urban Development. The table below lists current or past ministries.
