Location
Jigawa State is one of thirty-six states that constitute Federal Republic of Nigeria. It is situated in the northwestern part of the country between latitudes 11.00°N to 13.00°N and longitudes 8.00°E to 10.15°E. Kano State and Katsina State border Jigawa to the west, Bauchi State to the east and Yobe State to the northeast. To the north, Jigawa shares an international border with Zinder Region in The Republic of Niger, which is a unique opportunity for cross-border trading activities. The government readily took advantage of this by initiating and establishing a free trade zone at the border town of Maigatari in Niger.
