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.

UFS celebrates Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities

Future sustainable partnerships in education will survive only if all partners are committed, honest, and transparent.

This is the view expressed by the Free State MEC for Education and UFS Council member, Tate Makgoe, during the panel discussion at the Qwaqwa Campus of the University of the Free State celebrating Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities. The topic was “The future partnership models for education in Africa”.

“Over the years, the partnership between the Free State Department of Education, the UFS, and Kagiso Trust has helped to expose the potential in our mainly rural children in the Qwaqwa area of the Thabo Mofutsanyana district,” said Makgoe.

”When we started in 2009, the matric pass rate in the district was 64%, and this rose to 87% in 2014. In Qwaqwa alone, we have managed to build 51 computer and 26 physical sciences laboratories. It was these laboratories that enabled the Free State to be the best performing province in the Physical Sciences in 2013,” added Makgoe.

“None of these achievements would have been possible if all the partners had not been committed to the course. Partnerships built on honesty and transparency are the best model, which we hope to export to other provinces and, indeed, countries,” Makgoe said.

Representing the UFS on the panel was the Director of Community Engagement, Bishop Billy Ramahlele, who added that collaborations can be successful only if the leadership was exemplary.

“As the university, we have had many collaboration with various government departments, and great strides have been achieved only with the Department of Education under the leadership of MEC Makgoe,” said Ramahlele.

”With the MEC on board, the UFS ended up dedicating its South Campus in Bloemfontein to supporting Free State schools. We now have 70 schools that benefit from live television broadcasts of lessons by some of our outstanding academics. This also enables our best academics to make a valued contribution to empowering our teachers. It also allows the university to maximise scarce resources to attain social cohesion,” he said.

In his remarks, Kagiso Trust Trustee, Dean Zwo Nevhutalu, said that Kagiso Trust was looking forward to continue working with its partners to maximise outcomes through limited resources.

“Kagiso Trust will continue to work with the poor and the marginalised and there is no better partner than the government itself. The government provides basic services, and education is one of them. This allows us to be innovative and not just dump books and equipment at schools because we are forced to by our corporate social investment obligations. Therefore, we challenge the government also to be innovative in building a sustainable future partnership model in education,” he said.

Among the dignitaries attending the panel discussion were Kagiso Trust Chairman, Dr Frank Chikane, and the late Dr Beyers Naude’s family.
