From Cathedral Peak to your tap: the role of mountains in providing water

05 July 2022 | Story Mandi Smallhorne

Why mountain research matters

“I don’t think South Africa is prepared for the possibility of a Gauteng Day Zero drought,” said Professor Francois Engelbrecht, director of the Global Change Institute at the University of the Witwatersrand.

Professor Engelbrecht was a keynote speaker at a session of the Southern African Mountain Conference 2022, held in the Drakensberg in mid-March this year and supported by, among others, the Afromontane Research Unit at the University of the Free State (UFS). The session, hosted by international network, GEO Mountains, looked at Long-term monitoring activities and associated data availability for climate change-related applications across Africa’s mountains: status quo and next steps.

The professor went on to say we came very, very close in the 2015-2016 drought, when the Vaal Dam dropped to 25% of capacity. Had it dropped just a bit more, to 20%, the most densely populated province in South Africa, our economic hub, would have been in serious trouble, as there would have been too little water to enable pumping the last dregs into the province.

What’s the link between a Day Zero event in Gauteng and data about mountain environments?

Think of the water towers that dot the Highveld landscape in Gauteng, very visible to residents of the suburbs. Mountains can be seen as massive ‘water towers’ that provide water to people hundreds, even thousands, of kilometres from their foothills. As Dr James Thornton of GEO Mountains, co-host of the session, explained, mountains provide a flow of ecosystem services; water provision is just one of them, but it is of critical importance. “The mountains are crucial for this, due to the orographic enhancement of precipitation.” The shape and topography of mountains (their orography), forces moist air upwards into cooler air at higher elevations – an effect called ‘orographic uplift’ – so that vapour held in the air condenses into water.

So as moisture-laden air sweeps in from the warm Indian Ocean to the east of us, it encounters the upward thrust of the long Drakensberg chain of mountains, from the Eastern Cape through Lesotho and KwaZulu-Natal and on, up to the Wolksberg Mountains in Limpopo. The upward movement of the air into colder regions triggers precipitation – rain, mist, sometimes snow.

And that moisture, falling on the soil and rocks in cool mountain air, is also less likely to evaporate and return rapidly to the atmosphere, as it might do on the coastal plains and lowlands.

The result? The most obvious consequence is waterfalls glittering in the mountain cliffs and swollen streams rushing down the slopes. Look at maps and you’ll see rivers springing from mountain sources everywhere in the world, like the Tugela heading east and the Orange flowing west from the Drakensberg in South Africa and Lesotho, or the Ganges and Indus rising in the Himalayas and the Rhine and Rhône rising in the Alps.

Mountain water also seeps into the ground, making its way through soil and rocks and recharging the groundwater within and beyond the mountains and their foothills. This recharge of the water table from high up in the mountains also contributes to streams and rivers that supply so much of our water needs, scientists have shown.

Mountain water in Gauteng

Gauteng residents are well aware of the role of the Vaal River in the Vaal Water Supply System, but do we understand just how much of our water originates in the Drakensberg? According to the Water Research Commission “transfers from the Maloti Drakensberg (34.4%) and the Northern Drakensberg SWSA (18.9%)” are critical to our water supply. That’s a little more than half our water in Gauteng coming from the Drakensberg.

Engelbrecht and his co-authors wrote a few years ago: “Except for the Southern Cape, the Drakensberg is the single most important source of water in Southern Africa and supplies regions where the bulk of the population resides.” (The Drakensberg Escarpment as the Great Supplier of Water to South Africa, S.J. Taylor, et al, in Developments in Earth Surface Processes Volume 21, Mountain Ice and Water, Investigations of the Hydrologic Cycle in Alpine Environments.) But, they added, due to population growth and other pressures, “In South Africa, it is now expected that demand for water will exceed supply by 2025 if nothing is done to supplement current water resources.”

That in itself is reason enough to focus on monitoring our mountains, and to support scientists observing and gathering data there. But add that to Professor Engelbrecht’s prediction that “multiyear El Nino-type droughts may plausibly occur from the mid-century (2030-2060) onwards” due to the climate change crisis, and it’s clear that we desperately need to understand the detail of how our mountains provide us with water; we urgently need to understand what is changing in the mountains.

Research matters

The ongoing and rapid changes we’re seeing in these very sensitive environments, from changing precipitation patterns, to changing land-use, to increases in population, is why we really need to “monitor and track these changes, to understand the biophysical processes and their interaction with society, and to be able to better estimate the chance, for instance, of future extreme droughts on a more local scale so we can develop measures for mitigation and adaptation,” said Dr Thornton. Better management of upstream water resources – such as the massive ‘water tower’ in the Drakensberg and elsewhere – is one tactic we should be vigorously pursuing.

There is a paucity of data about our precious mountainous areas across the world, but especially in Africa, and one of the messages of this workshop and of the conference as a whole was the importance of not just doing the monitoring and gathering of data, but making it readily accessible to all.

Dr Susan Janse van Rensburg (of the South African Environment Observation Network or SAEON, a national facility of the National Research Foundation) spoke about the in situ environmental monitoring that is being done in important mountain areas, including Cathedral Peak, the heart of the Central Drakensberg where the conference was being held. She introduced SAEON’s new Data Portal for researchers to access and share data about mountains – and not just in South Africa, but across the whole continent.

Omar Seidu gave a presentation on an initiative called Digital Earth Africa which collates and curates satellite data – including data on mountains. And GEO Mountains itself runs inventories which “seek to identify, link up, and make accessible existing data and information resources across the world’s mountains”.

“We’re trying to make it straightforward for researchers on the ground to make their datasets available to anybody if they choose to do so,” said Dr Thornton.

Research, observations and data-gathering on the ground (and from satellites) is the foundation for intelligent analysis, which results in solid evidence that can guide policymakers and the public to make the best choices. Mountains, our water towers, have perhaps not been enough of a focus for society in the past; information about their vital role in something as basic as water provision, and better understanding of the processes that furnish us with water, will surely help us to both mitigate and adapt to a future in which water scarcity looms so large.

Institutional research culture a precondition for research capacity building and excellence

2004-11-16

A lecture presented by Dr. Andrew M. Kaniki at the University of the Free State Recognition Function for research excellence

16 November 2004
The Vice Chancellor, Prof. Frederick Fourie
Deputy Vice Chancellors, Deans
Awardees
Colleagues and ladies and gentlemen

It is a great pleasure to be here at the University of the Free State. I am particularly honoured to have been invited to present this lecture at the First Annual Recognition Function for Research Excellence to honour researchers who have excelled in their respective fields of expertise. I would like to sincerely thank the office of the Director of Research and Development (Professor Swanepol), and in particular Mr. Aldo Stroebel for facilitating the invitation to this celebration.

I would like to congratulate you (the UFS) for institutionalizing “celebration of research excellence”, which as I will argue in this lecture is one of the key characteristics of institutional research culture that supports research capacity building and sustains research excellence.

Allow me to also take this opportunity to congratulate the University of the Free State for clocking 100 years of existence.

Ahmed Bawa and Johan Mouton (2000) in their chapter entitled Research, in the book: Transformation in higher education: global pressures and local realities in South Africa (ed. N. Cloete et. al Pretoria: CHET. 296-333) have argued that “…the sources of productivity and competitiveness [in the knowledge society and global economy] are increasingly dependent on [quality] knowledge and information being applied to productivity”. The quality knowledge they refer to here is research output or research products and the research process, which (research) as defined by the [OECD] Frascati Manual (2002: 30) is:

“…creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man, culture and society, and the use of this stock of knowledge to devise new applications”

The South African Government has set itself the objective of transforming South Africa into a knowledge society that competes effectively in the global system. A knowledge society requires appropriate numbers of educated and skilled people to create quality new knowledge and to translate the knowledge in innovative ways. To this end a number of policies and strategies like the Human Resource Development [HRD] Strategy for South Africa, the National Plan for Higher Education (NPHE) and the South Africa’s Research and Development [R&D] Strategy, have highlighted human resource development and the concomitant scarce skills development as critical for wealth creation in the context of globalization. The key mission of the HRD Strategy for instance is:

To maximize the potential of the people of South Africa, through the acquisition of knowledge and skills, to work productively and competitively in order to achieve a rising quality of life for all, and to set in place an operational plan, together with the necessary institutional arrangements, to achieve this.

The R&D Strategy emphasizes that maximum effort must be exerted to train the necessary numbers of our people in all fields required for development, running and management of modern economies. Higher education institutions like the University of the Free State have a key role to play in this process, because whatever form or shape a university takes, it is expected to conduct research (quality research); teach (quality teaching – and good graduates); and contribute to the development of its community! Thus the NPHE states that the role of higher education in a knowledge-driven world is threefold:

Human resource development;

High-level skills training and

Production, acquisition and application of knowledge.

Quality research output or knowledge which as argued is critical in determining the degree of competitiveness of a country in the knowledge economy is dependent upon quality research (process). Both the process of producing quality research and its utilization cannot and does not happen in a vacuum. It requires an environment that facilitates the production of new knowledge, its utilization and renewal. It requires skilled persons that can produce new knowledge and facilitate the production of new skills for quality knowledge production. Such an environment or in essence a university must have the culture that supports research activity. Institution research culture (that is a conducive and enabling institutional research culture) is a precondition to research capacity building. Without an institutional research culture that facilitates the development and nurturing of new young researchers it is difficult, if not impossible for a university to effectively and efficiently generate new and more quality researchers. Institutional research culture is also necessary to sustain quality research and quality research output or research excellence. It facilitates the development and sustenance of the institutional and people capacities required to do research produce quality research and generally attain research excellence!

We do recognize that the patterns of information and knowledge seeking, and knowledge generation vary among field or disciplines. For example, we know that in the humanities knowledge workers often work individually, and not as collaboratively as do those of the sciences, they all however, require supportive environments – institutional research culture to achieve and sustain research excellence. An institution does not simply attain a supportive research culture, but as Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues, research culture has to be grown [and maintained]. It unifies all natural and engineering scientists; medical researchers, humanists, and social scientists.

I therefore am of the view that Institutional Research Culture is critical to research capacity building and research excellence. I therefore want to spend a few minutes looking at the characteristics of research culture. To be effective, institutional research culture has grown and sustained not only at the institutional level, but also at the faculty, school and departmental levels of any university.

What is Research Culture?

In the process of researching on institutional research culture I identified several characteristics. Many of these overlap in some way. I want to deal with some of these characteristics; some in a little more detail while others simply cursorily. In the process what we should be asking ourselves is the extent to which an institution, like the University of the Free State, and its faculties, individually and severally, is growing and or sustaining this culture.

Institutional Research Strategy: As a plan of action or guide for a course of action, the institutional research strategy must spell out research goals that a university wants to achieve. It must be a prescription of what the university needs to be done with respect to research. As a strategy it is neither an independent activity nor an end in itself, but a component part and operationalization of the university policy or mission. ( Related to this is the Establishment of Institutional research policies)

Includes and makes public the targets, e.g. achieve so many rated scientists and make sure that every year we have so many SAPSE publications. That way people keep an eye on research agendas of the university and nation.

The UFS is obviously on its way, having launched its own Research strategy (A Strategic framework for the development of research at the University of the Free Sate. August 2003). Note that this strategy refers specifically to the “Culture of research” Fig 1

A set of administrative practices to support and encourage research. Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues that that research activity and output within the her Faculty (Arts) were very low and, in spite of the numbers of staff, with no Associate Dean for Research in the Faculty as though they had accepted that research belonged to Medicine and Science and Engineering, and teaching, separated from inquiry, belonged to the Arts. With the change in the thinking about research and development of research culture, it became clear that there was a major role for research support in a faculty her size (now about 360 full time continuing academic staff). The faculty developed a support system for research and began to address the SSHRC issues.

Reduce the bureaucracy system and micromanagement of research! This however, also implies that there is capacity and policies and procedure to manage and guide research processes

Establishment of Intellectual Property regulations and assistance

Research ethics policy and safeguarding by research administration

Focused, applied and suitable nature of the delivery mode (an institution open to new methodologies for conducting research

Programmes suited both full and part-time study particularly at graduate level (Mainly at Faculty/school and department level, and depending on what’s manageable)

Hiring senior academics to engage in, teach on and supervise postgraduate students to facilitate exchange of and transfer ideas and most importantly mentorship especially in view of declining numbers of researchers in particular fields

Quality instruction and facilitation in learning about research processes

A high retention rate of students maintained by the supportive and challenging learning environment and the use of online facilities to support collaboration and in-class learning

Availability of research grants: and awareness of sourcing funds from external sources like the National Research Foundation; Water Research Commission; Medical Research Council, private philanthropies and others outside the country. For example an institution should be able to assess how much of the slice the available funds (NRF etc) its able acquire and possibly top slice from institutional budget.

Adequacy of the financial reward system to encourage university staff members to do research (General Celebration of achievement for research excellence and achievement. This ranges form Annual reports mention; celebratory dinner. At Alberta researchers were given lapels. I don’t know of any academic who do not feel a sense of achievement to get into print or recognised. Access to research facilities within and outside the institution

Provision of infrastructure to support university-based research (e.g. equipment, admin support, etc.) – but also awareness of publicly funded and available research facilities and equipment!

Internet connectivity and changes in the bandwidth of the internet to download articles

Subscription to related bodies by the library so that researcher can download articles

Facilities and resources to attend international conferences to keep one updated

Number of visiting professors/speakers targeting senior scholars and invite them to lunch to ask them to participate and to encourage their best graduate students to do so within the institution and across institutions

Research training seminars for research students including young academics

Participation of staff/students in delivering research papers to national and international conferences

Establishment of research groups to provide interaction frameworks to achieve critical mass of research-active staff

Facilitation for more research time: Targeting new scholars and giving them reduced teaching loads in their first year or two for the purpose of developing their research programs. For the purpose of helping new colleagues to see the shape of South African research support, personalizing it, and creating research community

Take research to the community and argue its necessity, and utility

And, finally celebrating excellence. We must recognize achievement - parties and public recognition for colleagues who achieve splendid things in their research.

In conclusion, I want to reemphasize that research culture has to be grown it does not simply exist in an institution. If it is grown it needs to be nourished, nurtured and sustained. An institution cannot simply leave on borrowed reputation and expect to remain research excellent. It is on this basis that instruments like the National Research Foundation rating system recognizes excellence within a given period of time and not necessarily for a life time! This it is believed encourages continued research excellence.
