4.22.1.3 Pedology, agriculture and land use<br />

The soils in the Levuvhu sub-catchment can be divided into three main groups:<br />

• Moderately deep, red-coloured sandy-clay loam soils on the tops of the hill slopes and undulating terrain in<br />

the uppermost reaches of the sub-catchment;<br />

• Shallow to moderately deep, reddish to tan coloured sandy soils lining the valley bottoms in the middle<br />

reaches of the sub-catchment; and<br />

• Small areas of clay-rich, blackish or mottled soils with a high organic content covering flood terraces close<br />

to the lower reaches of the Levuvhu River and the Limpopo River; in some parts (e.g. the Pafuri Floodplain,<br />

these soils have a high sodium content and dispersive characteristics).<br />

Most of the sandy-clay loam soils in the upper parts of the sub-catchment fall within a zone of higher rainfall and<br />

support extensive plantation forestry activities. The sub-catchment is under the jurisdiction of a formal water<br />

control a board that is responsible for irrigation water allocations from the four storage reservoirs. Further away<br />

from the main channels of the Mutale and Levuvhu rivers, land use consists almost entirely of subsistence rainfed<br />

cultivation of drought-resistant crops and small-scale livestock farming.<br />

The overall pattern of land use in the Levuvhu sub-catchment is relatively complex, and includes towns,<br />

collected or grouped (but not collective) villages and settlements, traditional family units, commercial and<br />

subsistence cropping of cultivated lands, natural forests and forest plantations, Nature Reserves and National<br />

Parks (the northern portion of the Kruger National Park).<br />

Land use in the upper reaches of the sub-catchment comprises mainly commercial framing and large plantation<br />

forestry estates, with natural forests on the watershed dividing the Mutale and Levuvhu catchments. The town<br />

of Louis Trichardt located on the sub-catchment boundary to the west is the main service and industrial centre<br />

for the upper portion of the sub-catchment.<br />

In the central reaches of the sub-catchment, the predominant land use consists of groups of villages serving<br />

nearby collected (but not collective) agricultural plots. This development hinges around the rapidly expanding<br />

urban centre of Thohoyandou, which is located close to the Levuvhu River. The central portion of the subcatchment<br />

is also used extensively for small and large livestock rearing. Further to the east, there is a transition<br />

in land use from villages and agricultural plots to traditional single-family subsistence agriculture. In the<br />

lowermost reaches of the sub-catchment, land use is entirely devoted to conservation in Nature Reserves and<br />

the Kruger National Park.<br />

The Tshikondeni Colliery is located close to the lower reaches of the Levuvhu River, whilst several closed and<br />

abandoned mines, as well as alluvial diamond prospecting areas, are located closer to the Limpopo River.<br />
