What are the advantages of greater Zimbabwe's geographical location?

The rise of Greater Zimbabwe as a major residence is of great significance. Its rise is also the process of the decline of another central city. This center is located in Maponggubudui, further south of the limpopo river River Basin, near the junction of Zimbabwe, South Africa and Botswana. The reason for the decline of this city is unknown, but it may be related to overgrazing and environmental degradation. It seems that this economic and political center moved from the limpopo river valley to the northern end of the plateau in the late13rd century. However, the geographical location of Greater Zimbabwe is not only conducive to gold mining, but also easier to reach the coastal areas of the Indian Ocean through the Sebi River, so it eventually replaced that city.
