The Mkomazi estuary
(30°12' S;
30°48' E)
lies south of the city of Durban in KwaZulu-Natal. The river is approximately 298 km long with a catchment area of 4 310 sq. km. Approximately 21% of the Mkomazi catchment was under agriculture. Most of this was commercial forestry and subsistence farming with some temporary commercial irrigated agriculture, temporary commercial dryland agriculture, sugar cane, and improved grassland also present. About 7% of the catchment comprised degraded shrubland and bushland. A large proportion of the Mkomazi catchment (72%) was natural. This was mostly made up of grassland, bushland and forest. There was little urban development (less than 1%) in the Mkomazi catchment and most of this comprised residential development, smallholdings and industrial development associated with the towns of Umkomaas near the coast and Ixopo and Richmond further inland.
