Tano South District is one of the 27 Districts in the Brong Ahafo Region of Ghana. It lies between latitudes 7º00’N and 7º25’ N and between longitudes 1º45 W and 2º15 W. It is bounded on the North and East by the Offinso and Ahafo-Ano South Districts, both in the Ashanti Region. On the South, it is bounded by the Ahafo-Ano North District, also in the Ashanti Region and on its West and South-West by Tano North District Assembly. Bechem is the district capital.
The District has a total land area of 635 square kilometres, which is 1.54 percent of the total land area of the Brong Ahafo Region. The District Strategic Location as the entry point into Brong Ahafo Region from southern Ghana puts it in a unique position to attract tourists if that sector could be well developed.
The chiefs and people of Derma, a predominantly farming community in the Tano-South District have appealed to the government to rehabilitate without delay, the 10 kilometre road that links the town to the Kumasi-Techiman highway.
