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.

Council on Higher Education LLB qualification review not yet complete
2017-05-16

The reaction from various stakeholders following the ‘Outcomes of the National Review of the LLB Qualification’ by the Council on Higher Education (CHE) on 12 April 2017 requires the CHE to clarify that the national review process has not been completed and is ongoing.

The peer-review process conducted under the auspices of the CHE is based on the LLB Standards Document which was developed in 2014-2015 with input from higher-education institutions and the organised legal profession. Following self-review and site visits by peers, the process is now at the point where commendations and shortcomings have been identified, and the statement of 12 April reflects those findings. All law faculties and schools have been asked to improve their LLB programmes to meet the LLB Standard, and no LLB programme has been de-accredited. All institutions retain the accreditation they had before the Review process began and all institutions are working towards retaining their accreditation and improving their LLB programmes.

The South African Law Deans’ Association (SALDA) has issued a set of responses regarding the LLB programme review. The following questions and answers were published to give more clarity on the questions raised.

1.    What is the effect of a finding of conditional accreditation?
The programme remains accredited.

(“Accreditation refers to a recognition status granted to a programme for a stipulated period of time after an HEQC evaluation indicates that it meets minimum standards of quality.”)

The institution must submit a progress report by 6 October 2017 that indicates how short-term aspects raised in the HEQC reports have been addressed and an improvement plan to indicate how longer-term aspects will be addressed.

2.    What is the effect of a finding of notice of withdrawal of accreditation?
The programme remains accredited.

The institution must submit an improvement plan by 6 October 2017 to indicate how the issues raised in the HEQC report will be addressed, including time frames.

3.    How does the finding of notice of withdrawal affect current students?
Students currently enrolled for the LLB programme at any institution are not affected at all. They will graduate with an accredited qualification.

4.    How does the finding of notice of withdrawal affect new applicants?
The programmes remain accredited and institutions may enrol new students as usual. This also includes students completing BA/BCom (Law) programmes who wish to continue with the LLB programme.

5.    How does the finding of notice of withdrawal affect prior graduates?
Degrees previously conferred are not affected.

6.    What happens when the improvement plans are submitted in October 2017?
The CHE will evaluate the plans when they are submitted, and the programmes remain accredited until a decision is taken whether the improvement plan is sufficient and has been fully given effect to or not. The institutions will have to submit progress reports to the CHE indicating implementation of measures contained in the improvement plan.

Should a decision at some stage be taken that a programme’s accreditation must be withdrawn, a teaching-out plan would be implemented so that all enrolled students would have the opportunity to graduate with an accredited degree.
