Sand River (Limpopo)
The Sand River or Polokwane River ( af, Sandrivier) is a watercourse in Limpopo Province, South Africa, a right hand tributary of the Limpopo River. Its new name "Polokwane River" is homonymous with the name of the town of Polokwane, formerly Pietersburg, about upriver from its mouth. The Sand River flows by the western edge of this town. Course It has its source south of Mokopane and flows northwards across central Limpopo Province until it cuts across the Soutpansberg through a deep gorge, the Waterpoort. Then it meanders northwards across the Lowveld until it joins the right bank of the Limpopo east of Musina. Although considered a perennial stream it is often dry in the winter. The veld in the Sand River basin has suffered much degradation, mainly due to overgrazing. There are some wetland zones in the basin. These areas are an important ecosystem for certain rare or endangered plants, as well as frog and bird species. There are 18 mines in the Sand River basin. Dams and tr ...

Soutpansberg
The Soutpansberg, (formerly ''Zoutpansberg'') meaning "Salt Pan Mountain" in Afrikaans, is a Mountain range, range of mountains in far northern South Africa. It is located in Vhembe District Municipality, Vhembe District, Limpopo. It is named for the Salt pan (geology), salt pan ( ve, Thavha ya muno, or "place of salt") located at its western end. The mountain range reaches the opposite extremity in the Matikwa Nature Reserve, some due east. The range as a whole had no Venda language, Venda name, as it was instead known by its sub-ranges which include Dzanani, Hanglip, Songozwi and others. Of late it is however known as Tha vhani ya muno, meaning "mountain of salt". The Soutpansberg forms part of the 'Vhembe Biosphere Reserve', which was designated as a biosphere reserve by UNESCO in 2009. The latter reserve also includes the Blouberg Range, Kruger National Park, Makgabeng Plateau, Makuleke Wetlands and the Mapungubwe Cultural Landscape. Geography The mountain is intersected by t ...

List Of Rivers Of South Africa
This is a list of rivers in South Africa. It is quite common to find the Afrikaans word ''-rivier'' as part of the name. Another common suffix is "''-kamma''", from the Khoisan term for "river" Meiring, Barbara"South African Toponymic Guidelines for Map and other editors: Fourth Edition" 12. Retrieved on 30 April 2013. (often tautologically the English term "river" is added to the name). The Zulu word ''amanzi'' (water) also forms part of some river names. The Afrikaans term ''spruit'' (compare spring) often labels small rivers.

Intermittent Stream
Intermittent, temporary or seasonal rivers or streams cease to flow every year or at least twice every five years.(Tzoraki et al., 2007) Such rivers drain large arid and semi-arid areas, covering approximately a third of the earth's surface. The extent of temporary rivers is increasing, as many formerly perennial rivers are becoming temporary because of increasing water demand, particularly for irrigation. Despite inconsistent water flow, intermittent rivers are considered land-forming agents in arid regions, as they are agents of significant deposition and erosion during flood events. The combination of dry crusted soils and the highly erosive energy of the rain cause sediment resuspension and transport to the coastal areas.(Tzoraki et al., 2009) They are among the aquatic habitats most altered by human activities. During the summer even under no flow conditions the point sources are still active such as the wastewater effluents, resulting in nutrients and organic pollutants ...

Mathala Dam
The mridangam is a percussion instrument of ancient origin. It is the primary rhythmic accompaniment in a Carnatic music ensemble. In Dhrupad, a modified version, the pakhawaj, is the primary percussion instrument. A related instrument is the Kendang, played in Maritime Southeast Asia. During a percussion ensemble, the mridangam is often accompanied by the ghatam, the kanjira, and the morsing. Etymology The word "Mridangam" is formulated by the union (sandhi) of the two Sanskrit words ''mŗt'' (clay or earth) and ''anga'' (limb), as the earliest versions of the instrument were made of hardened clay. Legend In ancient Hindu sculpture, painting, and mythology, the mridangam is often depicted as the instrument of choice for a number of deities including Ganesha (the remover of obstacles) and Nandi, who is the vehicle and follower of Shiva. Nandi is said to have played the mridangam during Shiva's primordial ''tandava'' dance, causing a divine rhythm to resound across the h ...

Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

Veld
Veld ( or ), also spelled veldt, is a type of wide open rural landscape in :Southern Africa. Particularly, it is a flat area covered in grass or low scrub, especially in the countries of South Africa, Lesotho, Eswatini, Zimbabwe and Botswana. A certain sub-tropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. Trees are not abundant—frost, fire and grazing animals allow grass to grow but prevent the build-up of dense foliage. Etymology The word ''veld'' () comes from the Afrikaans word for "field". The etymological origin is older modern Dutch ''veldt'', a spelling that the Dutch abandoned in favour of ''veld'' during the 19th century, decades before the first Afrikaans dictionary.Eric Anderson Walker (ed). The Cambridge History of the British Empire, Volume 4. Cambridge University Press 1963 (Afrikaans: pp. 890–894) A cognate to the English ''field'', it was spelt ''velt'' in Middle Dutch and ' ...
