There's nothing channelling on the terrain. Where should the mines be laid? Almost all vehicles can quite easily travel off-road, especially the military ones. No mountains or hills, thus no narrow valley. No irrigation channels limiting choice of route, nor drainage channels.

A couple wadis and the streets in settlements offer the only canalized terrain afaik.

Mines only played a significant role in Africa during 1940-1942 in the defence of fortified settlements (Tobruk) and at the natural bottleneck El Alamein.
