Editing Highveld (section)

==Urban areas and industry==
Cities located on the Highveld include [[Johannesburg]], [[Pretoria]], [[Bloemfontein]], [[Vereeniging]], [[Welkom]], [[Carletonville, Gauteng|Carletonville]], and the cities of the [[West Rand]] and [[East Rand]]. The diamond-mining city of [[Kimberley, Northern Cape|Kimberley]] lies on the border of the Highveld and the southeastern Kalahari.

About half of the [[gold]] ever produced in the world has been mined on the Highveld since 1880. The largest deposits are located in the Witwatersrand, which centres on Johannesburg, with smaller deposits in the northern Free State near Welkom and [[Virginia, Free State|Virginia]]. The Highveld is also exceedingly rich in [[diamonds]], [[coal]], [[vanadium]], and [[manganese]].

The pollution in this region is also very high principally due to coal [[thermal power station]]s producing [[nitrogen oxide]] and [[sulfur dioxide]].<ref>{{cite news|url=https://www.lemonde.fr/afrique/article/2019/06/26/dans-l-afrique-du-sud-charbonniere-la-population-est-prisonniere-d-une-pollution-mortelle_5481645_3212.html|title=Dans l'Afrique du Sud charbonnière, la population est prisonnière d'une pollution mortelle|newspaper=Le Monde|access-date=26 June 2019|date=26 June 2019|language=fr|trans-title=In South Africa, the population is trapped in deadly pollution}}</ref><ref>{{cite web|url=https://www.thesouthafrican.com/news/pollution-and-smog-plague-lives-on-south-africas-highveld|title=Pollution and smog plague lives on South Africa's Highveld|work=The South African|date=29 June 2019 |access-date=29 June 2019}}</ref>

[[Agriculture]] on the Highveld is generally dominated by extensive [[grain]] production and the grazing of [[beef cattle]], with more intensive production of [[maize]], [[wheat]], [[sorghum]], [[citrus fruits]], [[Macrotyloma geocarpum|groundnuts]], [[sunflowers]], and [[vegetables]], occurring in irrigated areas and farmland closer to urban areas. The peat base of the [[grassland]] acts as a natural filter, providing sources of clean water.
