The
Highveld is the portion of the South African inland
plateau which has an altitude above roughly 1500 m, but below 2100 m, thus excluding the
Lesotho mountain regions to the south-east of the Highveld. It is home to some of the country's most important commercial farming areas, as well as its largest concentration of metropolitan centres, especially the
Gauteng conurbation, which accommodates one-third of South Africa's population.
