Yolandi Schoeman
Dr Yolandi Schoeman is redefining the future of ecological restoration with innovative solutions for both Earth and space.

Dr Yolandi Schoeman, a Senior Lecturer in Ecological Engineering in the Centre for Mineral Biogeochemistry at the University of the Free State (UFS) and the Ecological Engineering Institute of Africa, was fascinated by the synergy between engineering and the natural sciences from a young age.
 
She said that the potential within ecological engineering to regenerate ecosystems at all scales, from the microscopic to vast landscapes, really drew her in. “This field offers solutions not only for daily sustainability challenges but also for the threats to planetary health and human well-being. However, when I was starting out, ecological engineering wasn't recognised as a formal career path in South Africa, and studying it in the United States wasn't feasible for me at the time. So, I explored various educational paths in civil engineering and natural sciences, aiming to merge these disciplines in my projects and research. My ultimate goal has been to establish and develop the field of ecological engineering both in South Africa and across Africa,” she explained. 

Conventional and extreme ecological engineering

Dr Schoeman’s work in ecological engineering spans two main areas: conventional and extreme ecological engineering. On the conventional side, she says she is focusing on projects like designing constructed wetlands to naturally treat water, implementing urban greening initiatives to cool cities and manage stormwater, and regenerating various habitats to strengthen biodiversity. In terms of extreme ecological engineering, she focuses on developing innovative solutions for ecosystems that have been severely impacted by disasters like industrial accidents or natural calamities. 

Additionally, she is leading efforts in astro-ecological engineering, applying these principles to rehabilitate severely damaged terrestrial environments while exploring their potential for extraterrestrial applications, advancing both sustainability and ecological restoration.

There are two moments in her journey that Dr Schoeman recalled helped shape her career. One was being invited to participate in the 2006 Brightest Young Minds initiative, hosted by the University of Stellenbosch. She said that it was the first platform where she could really develop and share her ideas and vision in ecological engineering. “I contributed to a publication titled Engineering Engineering, which focused on integrating nature into every facet of development and operations. That experience validated my vision of combining engineering and natural systems.”

The other experience came during her studies in Executive Leadership at the Skolkovo School of Management in Moscow. “I was tasked with leading a multidisciplinary, international team that had to create a sustainability strategy for a major international iron, steel and vanadium company. The project pushed me to defend sustainability solutions that would alter the way this industrial giant operated. It was a deeply challenging process that changed my perception of true sustainability and what it means to deliver solutions that are both impactful and make business sense. That moment forced me to step out of the comfort zone of conventional sustainability and reorient my path toward pursuing solutions that seemed almost impossible, but necessary.”

Advancing ecological engineering across Africa

Two of the most important research projects she has been involved in include advancing ecological engineering across Africa and restoring and managing ecosystems that are considered beyond conventional repair. The first project involved establishing an international institution that spearheads various innovative research areas, including exploring floating treatment wetlands, different types of constructed wetlands, and technologies for smarter ecosystem management in urban and rural contexts. “This comprehensive project has substantially elevated the global understanding and application of ecological engineering, addressing a spectrum of sustainability challenges,” she said.

In the second project she worked with a team that tackled severely degraded environments like post-mining landscapes, heavily polluted industrial sites, and areas where ecosystem functionality has been drastically compromised. She also aims to develop the projects further and to collaborate with agencies like NASA to design life-support systems for future space habitats. “These systems are not limited to space applications, but are also designed to address complex planetary health issues in extreme environments on Earth, such as war zones, nuclear disaster areas, and sites affected by climatic catastrophes,” she remarked.

Dr Schoeman is also responsible for the "Astroecological Engineering System" (AES). “This system uniquely integrates terrestrial ecological engineering principles with astro-ecological technologies to deal with some of the most challenging environmental restoration projects on Earth and potentially in future space habitats,” she stated, adding that AES is specifically designed for restoring heavily degraded or contaminated ecosystems – situations where traditional restoration methods are inadequate. 

Pushing the boundaries of what’s possible 

She believes AES is a versatile tool for addressing some of the most daunting environmental challenges we currently face. This passion for handling seemingly insurmountable problems is what drives her work. 

“These are the issues that often push the boundaries of what's possible in ecological engineering. Each project that seems 'impossible' provides an opportunity not just to solve a problem, but to innovate and create methods that can be applied globally. It's about turning what was once thought unachievable into tangible, impactful realities that improve our environment and our relationship with the natural world. I truly believe that humanity holds the pen that can rewrite our future.”

About the future, she says that over the next 15 years she would like to see extreme ecological engineering, supported by astro-ecological insights, evolve into a foundational strategy in global environmental management. This approach will be key in scenarios where traditional restoration methods are inadequate. “My goal is to integrate these advanced, resilient techniques into mainstream disaster response and urban planning processes worldwide, preparing ecosystems and communities to withstand and adapt to future ecological stresses,” she said.

She also envisions a future where the principles of extreme and astro-ecological engineering are routinely taught in academic institutions and incorporated into public policy. “By raising awareness and building expertise on a global scale, I aim to cultivate a new generation of engineers – those who are not only equipped to take on severe environmental crises on Earth but are also prepared for the ecological challenges we may face in space. This ambitious vision drives a shift towards more resilient and adaptive management of Earth's ecosystems, ensuring they thrive amidst the challenges of the 21st century.”

Centenary medals awarded
2004-10-15

Speech, Rector and Vice-Chancellor: Prof. Frederick Fourie

Op 28 Januarie 2004 het ons die honderdste herdenking van die geboorte van hier­die hoër onderwys instelling gevier met ‘n groot partytjie voor die Hoofgebou. Dit was ‘n wonderlike en vreugdevolle aand.

Die historiese prosessie tydens die amptelike opening van 6 Februarie 2004, in kleurvolle akademiese togas, vanaf ons wortels in Grey-Kollege tot by die Hoof­gebou, het die reistog vanaf die verlede na die hede treffend ge­simbo­liseer.

Talle ander eeufeesgeleenthede het gedurende hierdie jaar plaasgevind. Woensdagaand het ons die premiêre van ‘n dokumentêre film oor koning Moshoeshoe beleef – ‘n belangrike eeufeesprojek van die UV wat onder meer gemik is op die ontwikkeling van ‘ n gedeede geskiedenisbesef – a shared sense of history – and the celebration of a very special leadership, of a spirit of nation-building and reconciliation, in somebody like king Moshoeshoe (also MT Steyn and others…)

Last night we experienced a wonderful and moving honorary doctorary ceremony, with a wonderful group of South Africans like Khotso Mokhele, Antjie Krog, Jakes Gerwel, Van Zyl Slabbert, Jaap Steyn, Saleem Badat, and others - giving so much food for thought.

This evening, where we honour outstanding contributors to the development of this University, is a suitable moment to reflect on the course of the first 100 years of the University of the Free State.

1. ‘n Voëlvlug oor die geskiedenis: die vyf fases

1.1 Eerste fase: 1904 – 1927 (Eerste kwarteeu)

Eerste wankelende treë in die totstandkoming van die
Grey Universiteitskollege

Gedurende 1904 – 1920 word die eerste en mees basiese vakke in geestes- en natuurweten­skappe ingestel, eerste Senaat en eerste Raad saamgestel, en eerste geboue opgerig (hoofgebou en manskoshuis). Teen 1920 was daar egter slegs ongeveer 100 studente, die instelling was finansieel in die knyp, met geen vooruitgang en groei, en ook nie ‘n vaste rektor nie – klaar­blyk­lik was die GUK nog geen lewensvatbare instelling nie. Vrystaatse kinders word steeds eerder na ander universiteite gestuur.

Hierna maak ds JD Kestell, rektor 1920 – 1927, ‘n reuse bydrae om ‘n versukkelde, arm, klein universiteitskollege lewensvatbaat te kry. Hy slaag met fonds­insameling en oortuig Afrikaanse én Engelse ouers om hulle kinders na die GUK te stuur. Teen 1927, met 420 studente, word die eerste nederige mylpale van kritiese massa bereik te midde van ‘n steeds armoedige Vrystaat­se gemeenskap en ‘n studentekorps met gelapte klere. [Maar ook die tyd waarin die Reitz-saal, waarin hierdie plegtigheid plaasvind, gebou is.]

1.2 Second phase: 1927 – 1950 (Tweede kwarteeu)

The Grey University College becomes a fully fledged university

By 1950 the establishment of main basic and career-oriented faculties were completed – Faculty of Commerce in 1937; Faculty of Law as wel as the Faculty of Education in 1945. Student numbers reached 1000 in 1950.

Die UKOVS beleef en oorleef die Groot Depressie, die armblankevraagstuk, die Tweede Wêreldoorlog, taal- en politieke stryd onder Afrikaners, en die stryd van Nat vs Sap, ook op die kampus. Die tydperk word veral gestempel deur die taalstryd met DF Malherbe (rektor 1929 – 1934) as sterk kampvegter vir Afrikaans. Veral na 1948 volg rektor Van der Merwe Scholtz ‘n doelbewuste enkel­talige Afrikaanse rigting (Christelik-nasionaal).

1.3 Derde fase: 1950 – 1976 (Derde kwarteeu)

Ongekompliseerde groei ná onafhanklikheid

Hierdie periode word gestempel deur verkryging van onafhanklikheid as universiteit op 18 Maart 1950. Daarna beleef die UOVS onder rektore Scholtz, Flippie Groene­woud en Benedictus Kok stelselmatige groei sonder beduidende finansiële kommer. Die UV is duidelik ‘n Afrikaanse ‘volksuniversiteit’ op Christelik-nasionale grondslag, onlosmaaklik in­gebed in die dominante politieke bedeling van apartheid en afsonder­like ontwikke­ling. Dit is die hooggety van Afrikaner (en blanke) self­vertroue en heerskappy. Vir personeel sowel as studente is dit ‘n relatief onge­kom­­pliseerde tyd getipeer deur groeiende voor­spoed in die blanke en Afrikaanse gemeenskap, goeie werksvooruitsigte vir studente, kommer­lose studentepret, en min spanning op die kampus.

The academic focus is on teaching, especially to provide staff for the growing public service and education sectors. Research has a low profile. More career-oriented or professional faculties are established: agriculture in 1958 and the medical faculty in 1970. Student numbers reach 2000 in 1960, 4000 in 1970 en 7000 in 1975. Many new residences and academic buildings are erected, especially in the Kok-era.

Teen 1976 was die vernaamste boustene van ‘n medium-grootte universiteit in posisie: onafhanklikheid, genoeg fakulteite, genoeg koshuise en akademiese geboue, goeie sport en kultuur. Op die oog af is die ideaal van volwaardige, onaf­hanklike universiteit verwesenlik.

1.4 Vierde fase: 1976 – 1989

Op koers na die jaar 2000: van die statiese na vernuwing

Politieke onstabiliteit en oorgang in die land begin met die Soweto-onluste, die drie-kamer parlement, PW Botha se Rubicon-toespraak, noodtoestande, die ‘struggle’ en opkoms van UDF, en so meer. Die UOVS is swaar onder die indruk van die ‘totale aanslag’ en die regering se totale teen-strategie. Die Universiteit word polities en akade­mies geïsoleer en intellektueel gemarginaliseer. Ekonomies is dit moeiliker tye na die oliekrisis en die begin van hoë inflasie, en die Staat se finansies wat begin knyp.

Academically this period is distinguished by the strong stimulation and support of the research capacity and orientation by rector Wynand Mouton, which leads to a significant growth in research, especially in the natural sciences. The faculty of Theology is establishyed, the Sasol-UFS library erected. Student numbers continue to grow, but at a much slower rate then before.

Twee ander fasette kenmerk hierdie tydperk: eerstens die toelating van die eerste swart studente (nagraadse 1978, voorgraads 1988) en die begin van die era van multikulturaliteit; tweedens, die begin van subsidie- en finansiële probleme en die eerste rasionalisasie van personeel. Albei hierdie is voortekens van ingewikkelde jare wat sou volg vanaf 1990.

1.5 Fifth phase: 1990 – 2004: The turn of the century brings winds of change

(a) 1990 – 1996:

Die Francois Retief era word gedomineer deur die gevolge van die politieke verande­ringe deur president FW de Klerk en die vrylating van Nelson Mandela. Die UV ontwaak tot die realiteit van die oorgang na ‘n post-apartheid samelewing en komende ANC regering. Die eerste versigtige trans­for­ma­sie­stappe word ingestel, multikulturaliteit word die groot uitdaging, en die eerste fasiliterende strukture (bv. die Multikulturele Komitee) word gevestig. Die eerste senior swart personeel word aangestel.

The dramatic decision about the introduction of parallel-medium teaching in 1993 signals the start of multilingualism as well as a significant growth in the admission of black students. Total student numbers are stable at approximately 9000, but black student numbers grow to 36% in 1995. Initially the change to parallel-medium impact negatively on staff teaching load and hence onresearch outputs.

Die inkrimping in staatsubsidie lei tot ernstige finansiële probleme, besparings­pogings, grootskaalse rasionalisasie van personeel in veral die fakulteit Lettere en Wysbegeerte, spanning tussen Senaat en rektoraat oor finansies – en mismoedig­heid onder personeel.

(b) 1997 – 2004:

The time of rector Stef Coetzee and his successor is the era of the new democracy and transformation. At the beginning of this phase Afrikaans parents start sending their children to other Afrikaans universities; residence become half full. Tensions arise between student groups. This is followed by the large breakthroughs in student transformation in 1997, which normalises the situation. The University becomes a leader in transformation. This leads to the acceptance of the multicultural and multilingual character, on a Christian foundation, of the University. The name changes to the University of the Free State (UFS).

Met ‘n finansiële krisis en verdere rasionalisasie van personeel op hande word die akade­miese en finansiële ‘draaistrategie’ in Januarie 2000 geloods. ‘n Drama­tiese finansiële ommekeer lei tot herinvestering in kampus­fasiliteite en toerusting, ‘n toename in personeel en beduidende verhoging in vergoeding bokant inflasie. Terselfdertyd is daar ‘n opbloei in die akademie: innoverende onderrig­programme, e-leer, ‘n fokus op programgehalte. Konsolidering van fakulteite vind plaas, die Bestuurskool word gestig, daar is sterk internasio­na­lisering en groei in navorsing. Profes­sionele bemarking en strategiese kommunikasie verander die beeld van die UV.

Studentegetalle groei dramaties van 10 000 in 2000 na meer as
23 000 in 2003/4; groei moet nou beperk word. Afrikaanse studente keer terug; koshuise kry lang waglyste. Die verhou­ding tussen wit en swart studente op die hoofkampus is rondom 50:50.

The period ends with the incorporation of the Qwaqwa en Vista Bloemfontein campuses, the approval of a new language policy which also established multilingualism in management and administration, and purposeful efforts to consolidate the foundations of an institutional culture of multiculturalism, multilingualism, non-racialism and non-sexism – a culture of tolerance, embracement and justice in diversity. The Centenary is celebrated with harmony and prosperity on the campus in 2004 (although always with a good sprinkling of unexpected challenges and problems).

2. Vanaand bring ons hulde, en sê ons dankie aan, die bouers van die UV

Oor ‘n honderd jaar het honderde, duisende mense ‘n bydrae gelewer tot die UV se ontwikkeling.

Kom ons eer en dank diegene wat, 100 jaar gelede in a baie arm gemeen­skap wat bykans verwoes is deur die Anglo-Boere oorlog, nooit opgehou droom het oor ‘n eie universiteit om die jongmense te dien, om die mense te dien – die arm Vrystaatse mense van daardie tyd.

Let us honour and thank all those who painstaking built this university from very humble beginnings, from the first fragments and embrio of a university – through a hundred years of various wars, of the struggle, of poverty, of bad times but also good times.

In elke dekade, in elke een van die honderd jaar, is hierdie instelling gebou deur die harde werk, idealisme en verbintenis (“commitment”) van leiers, akademiese personeel, steundiens­personeel, dienswerkers. Laat ons hulle eer en dank.

Let us honour the spirit of commitment and ‘vasbyt’, of ‘never let go’, the determination to overcome obstacles, of timely and pre-emptive adjustment to new challenges and new needs, which made that possible.

Kom ons vier en eer die duisende studente wat in die 100 jaar hier was, wat die spesiale tradisies en spesiale gees geskep het van Kovsiekampus, van Kovsie studentelewe – en wat gedurig nuwe tradisies en gebruike geskep (en gepleeg) het, soos net studente dit kan doen.

Let us celebrate the way this University has, in the last 20 years, once again taken up the challenge of transformation and adjusting to new needs, serving all the people, especially those most in need at this time of our history – thereby closing the circle, going fully “from post Anglo-Boer War to Post-Apartheid”.

Kom ons vier, en wees innig dankbaar vir, die wyse waarop hierdie Universiteit in die laaste 5 jaar gedraai het, finansieel sowel as akademies, en die wonderlike periode van akademiese groei en ontwikkeling en verdieping waarin ons nou staan – tesame met die geleenthede wat QwaQwa en Vista Bfn vir ons bied. Hierdie voorspoed sien ons in die nuwe fisiese aangesig van die kampus, insluitend hierdie wonderlike Eeufeeskompleks.

Let us thank God, the Almighty, who has guided this university through a tumultuous century, for always being there for us, for blessing us in so many ways. In Deo Sapientiae Lux

So: vanaand is ons hier om erkenning te gee en dankie te sê…

Soveel mense het veel vroeër hul fondament-leggende bydraes gelewer, en alles wat ons vandag hier sien, moontlik gemaak. Selfs mense uit meer onlangse jare is reeds oorlede – enkeles terwyl hulle nog in diens van die UV was, ander na hul aftrede.

‘n Bepaalde groep was bevoorreg en geseend om in die laaste ongeveer 30 jaar by die UV betrokke te kon wees, én om vandag nog in die lewe te wees. Dit is van hulle wat vanaand hier is, en wat vanaand Eeufeesmedaljes ontvang.

Geweldige moeite is gedoen om hierdie proses van seleksie en keuring so billik en deeglik as moontlik te doen. Uiteraard is so ‘n proses nie volmaak nie en sal almal nie saamstem met die uitkomste van die proses nie. Groot moeite is egter gedoen in hierdie fase om mense nie verkeerdelik uit te laat uit of in te sluit in die toekenningslys nie, in volle bewustheid dat daar waarskynlik steeds foute gemaak sal word. Onvermydelik sal daar foute wees, of mense wat uitgelaat is. Ons vra daarvoor nederig om verskoning en begrip.

Billikheid, so ‘n belangrike rigsnoer vir hierdie Universiteit, veral in hierdie tye, lei ons ook dat ons oë oop is vir die bydraes vir mense uit alle afdelings van die Universiteit, wat lei tot ‘n bepaalde balans tussen fakulteite, tussen fakulteite en steundienste, tussen poskategorieë, tussen geslag en ras, en individue soveel as mense in spanverband.

In Deo Sapientiae Lux
