Landscape change studies bring better understanding of climate change

A study of subantarctic islands tells us that, in general, the Southern Hemisphere is experiencing a rise in temperature, with an increase in rainfall in some locations, and other areas becoming drier. The annual temperature and rainfall average remain the same in some places, but there is a change in seasonality and synoptic weather events.

This is according to Dr Liezel Rudolph, a lecturer in the Department of Geography at the University of the Free State (UFS). She recently returned from an expedition to Gough Island in the South Atlantic Ocean, supported by the South African National Department of Forestry, Fisheries and the Environment, the National Research Foundation, and the Royal Society for the Protection of Birds.

This teacher of modules on Process Geomorphology and fieldwork techniques at the UFS, says the objective of her work on the island was to do a geomorphological survey of the island and explore the suitability of geochronological dating techniques on the island’s substrate.

She explains that with geochronological methods one can determine the age of rock material as well as the rate of landscape change on the island. “In other words, dating when the volcano was formed and determining how long it takes for weathering to break down the rock material, and erosional processes to remove soil material.”

The research she is involved in, forms part of a SANAP-NRF-funded project, Sub-Antarctic Landscape Climate Interactions, which aims to better understand the landscape evolution of some subantarctic Islands and their response to long-term climate change.

Studying the past to understand the present

According to her, studying landscape change enables one to better understand climate change over a long period of time.

She states that the more regions are investigated, the clearer the picture of climate change will become. “The Earth is a large, complex system. By studying climate change in one location, one cannot simply assume that the same type and rate of change is occurring everywhere else. It would be like imaging a 1 000-piece puzzle by building with 10 pieces. The Southern Hemisphere is predominantly ocean, which makes it difficult to pin down land-atmosphere interactions – but the subantarctic islands give us the opportunity to create data points for the Southern Hemisphere, which would otherwise be a very large missing piece of the puzzle,” explains Dr Rudolph.

She says the interaction between ocean, atmosphere, and land remains complex and it is important to study the entire picture in order to fully understand how this is happening. Especially since the climate is changing at a drastic rate.

Dr Rudolph, whose research at the UFS is focused on constraining the last glaciation of subantarctic Marion Island though various proxies and dating techniques, says the subantarctic islands are very sensitive to changes in climate.

A clearer picture of climate change

She was part of previous expeditions to the island. Although all these expeditions had different goals, according to her, they all aimed to answer the same questions, which are how the island’s landscape has developed throughout history and what the climatic drivers were during its evolution.

“The landscape responds to changes in temperature and precipitation. Under colder, wetter conditions – when the island’s surface is subject to a freeze-thaw process – a range of peri-glacial landforms will develop. These landforms will still be evident in the landscape years later under a different climate, for example, warmer or drier conditions. We can study these landforms in real-time and establish whether they are actively forming or are relict features that formed under different climatic environments,” remarks Dr Rudolph.

The research, which is taking place in collaboration with the British Antarctic Survey, is co-led by Prof Werner Nel from the University of Fort Hare, and Prof David Hedding from the University of South Africa.

• Dr Rudolph is grateful to the Government of Tristan da Cunha, which is responsible for managing the conservation of Gough Island, for permitting them to do scientific work on the island.

MBA Programme - Question And Answer Sheet - 27 May 2004

2004-05-27

1. WHAT MUST THE UNIVERSITY OF THE FREE STATE (UFS) DO TO GET FULL ACCREDITATION FOR THE MBA PROGRAMMES?

According to the Council on Higher Education’s (CHE) evaluation, the three MBA programmes of the UFS clearly and significantly contribute to students’ knowledge and skills, are relevant for the workplace, are appropriately resourced and have an appropriate internal and external programme environment. These programmes are the MBA General, the MBA in Health Care Management and the MBA in Entrepreneurship.

What the Council on Higher Education did find, was a few technical and administrative issues that need to be addressed.

This is why the three MBA programmes of the UFS received conditional accreditation – which in itself is a major achievement for the UFS’s School of Management, which was only four years old at the time of the evaluation.

The following breakdown gives one a sense of the mostly administrative nature of the conditions that have to be met before full accreditation is granted by the CHE:

a. A formal forum of stakeholders: The UFS is required to establish a more structured, inclusive process of review of its MBA programmes. This is an administrative formality already in process.

b. A work allocation model: According to the CHE this is required to regulate the workload of the teaching staff, particularly as student numbers grow, rather than via standard management processes as currently done.

c. Contractual agreements with part-time staff: The UFS is required to enter into formal agreements with part-time and contractual staff as all agreements are currently done on an informal and claim-basis. This is an administrative formality already in process.

d. A formal curriculum committee: According to the CHE, the School of Management had realised the need for a structure – other than the current Faculty Board - where all MBA lecturers can deliberate on the MBA programmes, and serve as a channel for faculty input, consultation and decision-making.

e. A system of external moderators: This need was already identified by the UFS and the system is to be implemented as early as July 2004.

f. A compulsory research component: The UFS is required to introduce a research component which will include the development of research skills for the business environment. The UFS management identified this need and has approved such a component - it is to take effect from January 2005. This is an insufficient element lacking in virtually all MBA programmes in South Africa.

g. Support programmes for learners having problems with numeracy: The UFS identified this as a need for academic support among some learners and has already developed such a programme which will be implemented from January 2005.

The majority of these conditions have been satisfied already and few remaining steps will take effect soon. It is for this reason that the UFS is confident that its three MBA programmes will soon receive full accreditation.

2. WHAT ACCREDITATION DOES THE UFS HAVE FOR ITS MBA PROGRAMME?

The UFS’s School of Management received conditional accreditation for its three MBA programmes.

Two levels of accreditation are awarded to tertiary institutions for their MBA programmes, namely full accreditation and conditional accreditation. When a programme does not comply with the minimum requirements regarding a small number of criteria, conditional accreditation is given. This can be rectified during the short or medium term.

3. IS THERE ANYTHING WRONG WITH THE ACADEMIC CORE OF THE UFS’s MBA PROGRAMMES?

No. The UFS is proud of its three MBA programmes’ reputation in the market and the positive feedback it receives from graduandi and their employers.

The MBA programmes of the UFS meet most of the minimum requirements of the evaluation process.

In particular, the key element of ‘teaching and learning’, which relates to the curriculum and content of the MBA programmes, is beyond question. In other words, the core of what is being taught in our MBA programmes is sound.

4. IS THE UFS’s MBA A WORTHWHILE QUALIFICATION?

Yes. Earlier this year, the School of Management – young as it is - was rated by employers as the best smaller business school in South Africa. This was based on a survey conducted by the Professional Management Review and reported in the Sunday Times Business Times, of 25 January 2004.

The UFS is committed to maintaining these high standards of quality, not only through compliance with the requirements of the CHE, but also through implementing its own quality assurance measures.

Another way in which we benchmark the quality of our MBA programmes is through the partnerships we have formed with institutions such as the DePaul University in Chicago and Kansas State University, both in the US, as well as the Robert Schuman University in France.

For this reason the UFS appreciates and supports the work of the CHE and welcomes its specific findings regarding the three MBA programmes.

It is understandable that the MBA review has caused some nervousness – not least among current MBA students throughout the country.

However, one principle that the UFS management is committed to is this: preparing all our students for a world of challenge and change. Without any doubt the MBA programme of the UFS is a solid preparation.
