Ground spiny Cactus pear
Shredded, sun-dried, and coarsely ground spiny cactus pear (Opuntia ficus-indica and O. engelmannii), ready to be included in balanced diets for ruminant livestock (cattle, sheep, goats) and wild antelopes.

Prof HO de Waal, researcher in the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State (UFS), has developed a standard procedure for the processing of spiny cactus pear (Opuntia spp.) into livestock fodder. This will ultimately assist in the management of massive infestations of spiny cactus pear and help to convert underutilised farmland back to natural grazing land.

In addition to applying biological control agents, mechanical control is used to harvest alien spiny cactus pear, and the large volume of material is processed as livestock feed.

 

Introduced to South Africa

 

Three hundred years ago, seafarers visiting the Cape of Good Hope introduced the well-known invading alien spiny cactus pear to South Africa. These were later transported inland and by the 1950s about one million ha of South Africa had been invaded by the alien cacti.

Some regions in the Eastern Cape have been taken over by dense, impenetrable thickets of these cacti. Invasive alien plants (IAPs) such as cacti pose a direct threat to, among others, South Africa’s water security and productive use of land.

A range of methods is used to control IAPs, including mechanical, chemical, biological, and integrated control methods.

A control programme must include the three phases of initial control to drastically reduce the existing population; follow-up control of seedlings, root suckers, and coppice growth; and maintenance control on an annual basis to sustain low alien plant numbers.

 

Processing spiny cactus pears

 

According to Prof De Waal, the harvesting and processing of the spiny cactus pear is fairly simple. Although it requires a good measure of physical strength, perseverance, and the necessary protective clothing, the cacti can be processed by harvesting the plants; shredding the cladodes through a cladode cutter; then drying them in the sun, and lastly grinding it in a hammer mill. “The long spines are degraded mechanically by grinding the sun-dried cladode strips in a hammer mill before including it in balanced livestock diets,” said Prof De Waal.

Infestations will be opened, reclaimed, rehabilitated and the natural pastures (veld) allowed to revert back to grazing for livestock.

The National Resource Management Programme (NRM)P) will be approached for official support in clearing and rehabilitating massive areas of infestation by alien spiny cactus pear in the Eastern Cape. Such financial support will be an investment in reducing the infestation by invaders and the rehabilitation and sustainable use of natural resources in South Africa.

Pansalb’s Language Rights Monitor Project launched at the UFS
2007-01-25

 
 Attending the launch of the Language Rights Monitoring Project were, from the left: Mr Edward Sambo (acting head of Pansalb), Prof Engela Pretorius (Vice-Dean of the Faculty of the Humanities at the UFS), Prof Theo du Plessis (Director: Unit for Language Management at the UFS) and Mr Vusi Ntlakana (head of the Free State provincial office of Pansalb).

 
 Pansalb’s Language Rights Monitor Project launched at the UFS
 
The Unit for Language Management at the University of the Free State (UFS), in collaboration with the Pan-South African Language Board (Pansalb), today launched the Language Rights Monitor Project on the Main Campus in Bloemfontein.
 
In accordance with the Pansalb Act of 1995, Pansalb is responsible for the promotion and protection of language rights in South Africa, and is the chief funder of the project.          
 
The Language Rights Monitor Project was initiated in 2002 for a trial period of three years, with the aim of reporting to Pansalb, on an annual basis, on language-rights issues in South Africa, as reflected mainly in the printed media.
 
Since then, three reports have already appeared, covering various aspects relating to language rights, including, inter alia, language-rights complaints, language-rights issues, language litigation, as well as research on language rights in South Africa. Profs Johan Lubbe and Theo du Plessis, as well as Dr Elbie Truter, all associated to the UFS, were responsible for the compilation of the first three reports.
 
During 2006, Pansalb decided to establish the project for an unspecified period of time at the Unit for Language Management at the UFS. It is precisely for this reason that the project is being launched. The South African Language Rights Monitor will henceforth appear annually as a prestige publication of Pansalb, compiled by staff associated with the Unit.
 
However, Pansalb has also decided to further consolidate the project, as a result of the need for a more immediate report, as well as the need to include records drawn from newspapers published in the African languages. It was therefore decided that, as from September 2006, a monthly South African Language Rights Bulletin would also be launched. 
 
Such a bulletin would provide an overview, on a monthly basis, of developments in South Africa concerning language rights, and would enable Pansalb to become more actively involved in crisis situations in which mediation is urgently needed. Two monthly bulletins have already appeared, and were favourably received by Pansalb. During the launch of the project, this bulletin was also introduced to the public for the first time.
 
With the official launch of Pansalb’s Language Rights Monitor project in the Free State, emphasis will be placed on the leading role played by this province, and more specifically by the UFS, in the development and implementation of a multilingual policy.
 
In future, more information on the situation regarding language-rights issues in South Africa will be made available from Bloemfontein, for the benefit of South Africa’s language-rights watchdog, Pansalb, but also for the benefit of other institutions involved in language-rights issues.
 
A constructive contribution will thus be rendered to the cultivation of language justice, an important element of the democratisation process in South Africa.
