Les sanctions promulguées à l’égard de la Russie du fait de la guerre en Ukraine ont des conséquences significatives en ce qui concerne la recherche en Arctique, où jusqu’en 2022 scientifiques occidentaux et russes parvenaient à collaborer en bonne intelligence. La nouvelle donne géopolitique nuit à la collecte de données indispensables pour comprendre l’ampleur du changement climatique.


Élément consensuel de la gouvernance régionale de l’après-guerre froide, la recherche scientifique en Arctique a longtemps constitué un modèle de coopération et dans cet espace particulièrement exposé aux effets rapides du changement climatique. Mais depuis l’invasion à grande échelle de l’Ukraine par la Russie en février 2022, les sciences polaires dans la région arctique voient leur fonctionnement perturbé par la rupture des coopérations avec les chercheurs russes.

Vulnérable aux tensions diplomatiques et géopolitiques, la communauté scientifique a mis en garde contre les risques d’une paralysie prolongée des coopérations. Durablement fragilisés, les mécanismes institutionnels dans la région polaire peinent à rétablir un dialogue solide alors que l’architecture de gouvernance qui encadre les activités scientifiques sombre progressivement dans une forme de zombification.

Crise existentielle pour le Conseil de l’Arctique

Le Conseil de l’Arctique, qui joue un rôle prépondérant dans la coordination de la recherche scientifique, notamment dans les sciences du climat, a suspendu ses activités en mars 2022 avant de les reprendre prudemment, sans la Russie.

En février 2024, l’organisation régionale annonce sa volonté de relancer progressivement les groupes de travail avec la Russie via des formats virtuels. Toutefois, les divergences désormais structurelles dans les domaines politique, économique et militaire rendent un retour à la situation d’avant-guerre peu probable. Le récent retrait de la Russie du programme multilatéral sur la sécurité nucléaire, notamment en Arctique, illustre son désengagement croissant vis-à-vis de ses partenaires occidentaux.

Alors que la Norvège vient de transmettre la présidence du Conseil au Danemark, l’avenir de l’institution est obscurci. Pour tenter de relancer cette plate-forme intergouvernementale, la présidence danoise (2025-2027) fait des enjeux environnementaux une priorité afin de préserver une instance régionale essentielle. Mais les défis liés à l’organisation interne du royaume – composé de trois entités distinctes (Danemark, îles Féroé et Groenland) –, ainsi que les tensions entre Washington et Copenhague concernant l’avenir du Groenland, n’inspirent guère d’optimisme.

Le retour de Donald Trump à la Maison Blanche en janvier 2025, marqué par un durcissement diplomatique, ajoute à l’incertitude. Outre les coupes budgétaires dans les programmes de recherche scientifiques, qui affectent la surveillance climatique en Arctique, son aversion pour les structures multilatérales pourrait fragiliser davantage l’organisation.

Au-delà du Conseil de l’Arctique, c’est l’ensemble des réseaux et structures de coopération scientifique qui pâtissent de la configuration géopolitique de ces trois dernières années. Les sanctions occidentales ont en effet profondément perturbé le financement, les échanges académiques, les déplacements et même les publications des chercheurs russes.

Face à cet isolement, la Russie s’est tournée vers les pays des BRICS pour développer de nouvelles collaborations dans les sciences polaires. Cette fragmentation des relations diplomatiques met dangereusement en péril la recherche en Arctique. Depuis, des voix se sont élevées pour réintégrer les chercheurs russes, soulignant l’impérieuse nécessité de maintenir les échanges scientifiques dans un contexte d’urgence climatique.

Un grand risque pour la science du pergélisol

La fragmentation de l’espace polaire fait peser de graves menaces sur la recherche sur le pergélisol, ce sol perpétuellement gelé, parfois depuis des millions d’années, qui recouvre environ 15 % des terres émergées de l’hémisphère nord. Dans le contexte des changements climatiques globaux, l’étude de ces sols est fondamentale pour anticiper leur dégradation.

En effet, ils contiennent d’importantes quantités de matière organique et de méthane – un puissant gaz à effet de serre – qui pourraient significativement contribuer à l’augmentation de la concentration de carbone dans l’atmosphère, amplifiant ainsi le réchauffement actuel. À l’origine, la coopération scientifique internationale autour du pergélisol terrestre s’est structurée en pleine guerre froide. À l’instar de l’astrophysique ou la médecine, les sciences polaires y ont acquis une dimension géopolitique, servant d’interface entre les États-Unis et l’Union soviétique malgré leurs rivalités.

Avant le conflit ukrainien, la communauté alertait déjà sur les lacunes des systèmes de surveillance et de gestion des infrastructures arctiques, tout en pointant l’absence d’harmonisation des données. Le dégel du pergélisol, amplificateur critique du réchauffement climatique, représente pourtant une menace à long terme pour la sécurité internationale. Or, sans standards communs, l’évaluation globale de ses effets reste partielle.

La guerre a brutalement révélé ces fragilités. Cette rupture reconfigure la circulation des données sur le pergélisol autour de trois dynamiques : 1) la création d’un angle mort occidental ; 2) l’isolement structurel russe ; et 3) l’émergence des puissances asiatiques dans ce champ de recherche.

1) La fin des missions scientifiques occidentales en Russie prive les chercheurs de données cruciales pour modéliser l’évolution du pergélisol. Les alternatives comme la télédétection ou l’IA ne compensent pas totalement cette perte, créant un biais dans la fiabilité des études.

2) Malgré la rupture avec l’Occident, la Russie renforce ses capacités de surveillance via des projets nationaux, comme ses 140 stations de mesure des émissions de gaz à effet de serre. Toutefois, ces données, difficilement accessibles pour les Occidentaux désormais, peinent à influencer les politiques publiques russes, ce qui complique la coordination internationale.

3) La Chine et l’Inde, motivées par leurs propres zones de pergélisol (comme le plateau tibétain), investissent massivement dans la recherche polaire et collaborent avec la Russie. La Chine, notamment, étudie les liens entre les virus arctiques et tibétains, ce qui justifie son engagement accru en Arctique.

Ce bouleversement géopolitique a non seulement suspendu des projets de recherche, mais aussi rendu obsolète le modèle de coopération post-guerre froide. Désormais, la circulation des connaissances épouse les fractures géopolitiques, compromettant une réponse collective internationale à la crise planétaire.

La Chine et l’Inde en embuscade ?

Ces dynamiques esquissent une reconfiguration majeure de la recherche en Arctique : là où l’Occident et la Russie se distancient, les coopérations sino-russe et indo-russe se consolident, intégrant désormais des enjeux économiques stratégiques – notamment le déploiement d’infrastructures énergétiques (gazoducs et oléoducs) traversant des zones de pergélisol. Cette fragmentation des données, aggravée par l’absence de standardisation, accélère le découplage scientifique.

Cette évolution est susceptible de redéfinir fondamentalement les priorités de recherche sur le pergélisol. Les pays asiatiques, en particulier la Chine et l’Inde, dotées de politiques intégrées sur la cryosphère, pourraient tirer parti de leur accès privilégié aux données russo-occidentales en maintenant des collaborations étroites avec l’ensemble des pays arctiques pour établir leur prééminence scientifique, transformant ainsi les dynamiques de la diplomatie arctique. À plus grande échelle, ces acteurs pourraient restructurer le paysage de la recherche polaire en créant des synergies entre les différentes zones cryosphériques, comprenant les régions polaires et les glaciers, et en intégrant les impératifs climatiques à leurs calculs géostratégiques.

Le changement climatique étant désormais reconnu comme un enjeu de sécurité internationale, la surveillance du pergélisol se situe à l’intersection des sciences du climat et des considérations stratégiques. Cette convergence pourrait, à long terme, conférer à la Chine et à l’Inde une légitimité accrue pour repenser les cadres de la sécurité globale dans un contexte de transformations planétaires.

L’impérieuse nécessité de repenser la gouvernance des sciences polaires

L’exemple du pergélisol montre la façon dont les tensions géopolitiques consécutives à l’invasion russe de l’Ukraine compromettent la coopération scientifique internationale. La surveillance et la collecte de données sur la progression du dégel du pergélisol sont centrales pour anticiper l’évolution climatique mondiale. Loin des considérations court-termistes fondées sur les rivalités politiques et stratégiques, le travail des acteurs scientifiques privilégie le temps long du climat. Cette réalité impose aujourd’hui un changement de paradigme politique et institutionnel – ce que le géographe Klaus Dodds conceptualise comme l’avènement d’un monde « solide-liquide », dont le dégel accéléré du pergélisol constitue l’expression la plus tangible. Face au danger d’une opacité croissante entourant les projections climatiques, il est urgent de mettre en œuvre de nouveaux mécanismes de coopération, en repensant un cadre institutionnel à présent inadapté.

Cette réforme, qui s’impose, doit s’appuyer sur la création de nouvelles plates-formes collaboratives visant à restaurer la confiance et à adopter une approche intégrée de la cryosphère. Une coopération climatique entre les grandes puissances pourrait ainsi servir de pierre angulaire à un cadre institutionnel durable, essentiel pour concilier sécurité internationale et stabilité climatique tout au long du XXIe siècle. Dans un contexte marqué par la fragmentation structurelle du système international, la coopération scientifique dans le domaine environnemental devrait, in fine, permettre de dépasser les rivalités géostratégiques en Arctique.

Fun with fossils: South African kids learn a whole lot more about human evolution from museum workshops

Source: The Conversation – Africa (2) – By Shaw Badenhorst, Associate Professor in Zooarchaeology, University of the Witwatersrand

‘Find the fossil sites’ interactive display, Maropeng exhibition, Cradle of Humankind. flowcomm, CC BY

South Africa has one of the world’s richest fossil records of hominins (humans and their fossil ancestors). But many misconceptions still exist regarding human evolution, and school textbooks contain inaccuracies.

South Africans still have some of the lowest rates of acceptance of human evolution, mostly due to conflicting religious views. Religion and the non-acceptance of evolution hinders the understanding of evolution by teachers and learners.

It doesn’t help that school subjects (evolution being one of them) are often taught in unengaging ways, rather than interactive methods.

Many studies have shown that collaborations between schools and informal science learning centres, such as natural history museums, can have a positive effect on school learners. Inquiry-based activities at museums have been shown to help learners gain knowledge and meaning about the past. Museum visits foster “thinking skills” through guided conversation and questions asked by educators and learners. New information is gained through reasoning, inference and deduction, which enhance learning.

Evolution revolution: how a Cape Town museum exhibit is rewriting the story of humankind


In 2018, a team of researchers from the University of the Witwatersrand launched workshops on human evolution for grade 12 learners (in the final year of secondary school) in South Africa’s Gauteng province. The aim was to stimulate interest in the palaeosciences and improve learner performance. We worked with learners from 13 schools in the area. The workshops were conducted at the museum of the university’s Evolutionary Studies Institute.

From tests before and after the workshops, we found that they improved the learners’ understanding and acceptance of concepts related to evolution. More teacher training and school visits to museums and exhibitions could build on this success.

Workshops on human evolution

Our human evolution workshops were conducted with well-resourced and historically disadvantaged schools attending. The grade 12 learners, aged 17 and 18 years, visited the fossil preparatory laboratory, searched for clues in the museum while answering a worksheet, and did activities on human evolution using inquiry-based approaches.

These activities included measuring and describing skulls of apes and hominins, comparing hip bones to see whether the creature was able to walk upright on two legs, investigating stone tools, and drawing a phylogenetic tree (a diagram showing how species are descended from each other). Due to financial constraints, some of the workshops were held at the schools themselves.

The 687 learners wrote a test before and after the workshop to test their knowledge of hominin evolution. Their scores increased from an average of 39% to 61%.

The location of the workshops (either at the museum or at the school) did not affect the scores, suggesting that workshops can be scaled to reduce costs. Feedback from interviews indicated that learners regarded the workshops as beneficial, enabling them to learn new facts and gain a deeper understanding of human evolution. Teachers echoed the same view.

One learner said:

It was pretty enjoyable, and informative and interesting. Especially the part when we asked questions and we actually got answered. It helped us to understand the knowledge more.

Another said:

It is always better to physically see things as compared to seeing a picture of it, it is easier to understand it this way.

A teacher commented that learners

could literally see exactly what is happening and it is not just talk, they can touch it and they can take part in the experiment, which is not something they are exposed to at school.

It was apparent that learners understood human evolution better after the workshops. In the preliminary exam paper of Gauteng province, learners who attended the workshops scored nearly double (average 41%) the score of schools that did not attend (average 21%). While the scores are still low, and there is still much room for improvement, the results suggest that a short, hands-on workshop can make a major difference to learners.

The workshop also increased the acceptance of evolution from 41% to 51%. (It was not the purpose of the workshops to increase acceptance, but rather to improve understanding of the topic.)

Why the workshops worked

In our view, the workshops were successful because they used inquiry-based learning, learners working in groups using problem solving and physical handling of fossil casts. This enabled active participation in the learning process.

It’s time to celebrate Africa’s forgotten fossil hunters


With this approach, learners took ownership of the learning process and it developed their curiosity, interest and a desire to learn. The guidance of a subject expert during the workshops enhanced the quality of the workshops and the learning experience. It’s clear that visits to places like natural history museums created connections which helped with understanding concepts such as human evolution in the classroom, and developing an enjoyment of learning.

What’s next

We recommend that teachers receive training in human evolution and how to teach this topic. Common misconceptions of teachers can be identified through surveys, and intervention training must be planned around these misconceptions. The Gauteng Department of Education has a free professional development programme offering training to teachers (not publicly available), which can be used for this purpose.

Species without boundaries: a new way to map our origins


Various institutions in Gauteng offer exhibitions on human evolution and fossils, including the University of the Witwatersrand, the Ditsong National Museum of Natural History, Maropeng Cradle of Humankind, Sterkfontein Caves and the Sci-Bono Discovery Centre. The provincial education department must promote school visits to these places. Human evolution can be one of the most rewarding topics for learners, especially in a country where the fossil record is right on the doorstep.

It’s vital for grade 12 learners in South Africa to have a solid understanding of human evolution – it fosters critical thinking about science, identity and our shared African origins. This knowledge not only deepens their appreciation of the continent’s fossil heritage, but also counters misinformation with evidence-based insight.

Somalia at 65: what’s needed to address its dismal social development indicators

Source: The Conversation – Africa – By Ali A. Abdi, Professor, University of British Columbia

Somalia ranks among the lowest scoring countries in the United Nations Human Development Index. The index of 195 countries is a summary measure of average achievement in key dimensions of human development: a long and healthy life, years of schooling, and access to a decent standard of living. Ali A. Abdi, a scholar of social development education, examines Somalia’s failure to advance social development programmes.

What is socio-economic development and how does Somalia stack up?

Somalia is celebrating its 65th year of independence. This was marked officially on 1 July 2025.

Despite the pomp and circumstance, though, the country’s social development indicators are dismal.

Social development generally means visible improvements in the quality of life. People’s well-being is based on aspects of national progress like:

  • universally available good quality education and adequate healthcare

  • employment opportunities that generate liveable incomes and upward socioeconomic mobility

  • governance structures that protect people’s rights to security.

Somalia has failed to meet these human development targets.

Its low score in the UN index can be understood by looking at the statistics relating to education and health. In any society these act as foundational blocks for social development. But in Somalia:

  • children can expect to get an average of 1.72 years of education (the continental African average is 7.7 years)

  • there are 0.23 doctors per 10,000 people, and many doctors serve in fee-based private clinics which are out of reach for ordinary citizens in a country with US$600 GDP per capita income

  • the capital city, Mogadishu, with a population of 2.8 million, has only two fully public hospitals and they lack specialist services; patients who require specialist care must go to private hospitals

  • the youth unemployment rate is just below 70%.

With these social development liabilities, it’s no wonder that the country is the biggest per capita producer of both global refugees and internally displaced persons.

How did Somalia come to this?

The Somali state collapsed as a cohesive national entity in 1991. The military government that had been in power since 1969 was overthrown by armed opposition forces. The country slowly fragmented into quasi-self-governing regions. Transitional national governments have come and gone.

The current federal political structure came into being in August 2012. The Federal Republic of Somalia comprised five founding member states (there are now six).

The depressed social development situation is not the only obstacle facing Somalia. Other complexities include:

A governance system built on cronyism and political loyalty: Somalia’s national political leadership entrenched cronyism. In fairness, the same selectively applies to sub-national, federal member states leadership. This corrupt system has found traction in a country where professionals, young graduates and traditional leaders lack legitimate sources of income. This undermines good governance while creating discord within and among the federal government and federal member states.

Discord at national level and between national and sub-national leaders: The most recent example of this revolves around the national leadership’s 2024 attempt to change the interim constitution. The unilaterally proposed one-person-one-vote proposal runs counter to the 2012 framework through which the current federal system was created. This has fuelled yet another national controversy with less than a year to the next presidential election.

Externally constructed political and economic interventions: Somalia receives significant international aid to address political and developmental challenges. But the strings attached include the management of these funds by external entities. These donor priorities can be detached from immediate social development needs. And aid creates and sustains dependency and entrenches poverty.

What should the government prioritise and why?

The political class always says fighting terrorism is the top policy priority. This thinking, while viable for the current situation, ignores the potential to minimise terrorism by putting the basic needs of the public first, and especially the youth.

Somali leaders are duty-bound to shift focus. A good place to start is the basis of social development: security, education and healthcare. It falls upon them to marshal the country’s resources and capacities to improve the well-being of its citizens.

The national leadership also needs to restructure its relationship with federal member states. Distribution of development resources (including foreign aid) must be fair, not based on political alliances.

Somalia also needs to reform the government’s policy on public appointments. People must get jobs based on their educational background, professional experience, incorruptible character and institutional accountability.

The country has impressive natural resources. There’s huge untapped potential for fisheries and agriculture, which is the country’s economic backbone. The country also has untapped minerals and hydrocarbons wealth.

The above observations are not to say that the federal government should lose sight of the fight against the terrorist organisations. But the welfare of people, including job creation for young people, must be equally prioritised. That will surely advance much needed social development while also reducing the appeal of terrorism among the youth.

Ruth First and activist research: the legacy of a South African freedom fighter

Source: The Conversation – Africa – By Saleem Badat, Research Professor, UFS History Department, University of the Free State

Ruth First, born 100 years ago, was a South African freedom fighter, journalist and scholar who worked against the racist system of apartheid during white minority rule. She was assassinated by apartheid forces in her office at the Eduardo Mondlane University in Mozambique in 1982.

Her ideas, work and legacy live on. Sociologists Saleem Badat and Vasu Reddy have edited a new book called Research and Activism: Ruth First & Activist Research. We asked them about her and their project.


Who was Ruth First?

Heloise Ruth First was born on 4 May 1925 in Johannesburg to Jewish parents who had migrated from eastern Europe to South Africa in the early 1900s. Her parents were founder members of the South African Communist Party.

She joined the Young Communist League and the Federation of Progressive Students and graduated from the University of the Witwatersrand in 1946 with a Bachelor of Arts degree.

At 21, First joined the left-wing South African newspaper The Guardian. When it was banned, the New Age took its place until it too was banned in 1962. She served as the newspaper’s Johannesburg editor for 17 years.

In 1963, First was arrested at the University of the Witwatersrand library and held in solitary confinement for 117 days, during which time she was ruthlessly interrogated. The following year she and her three children left South Africa for England on an exit permit, where they joined her partner, the activist and politician Joe Slovo. She would not set foot again in South Africa. Continuing with her activist research in England, she taught at Durham University and then joined Eduardo Mondlane University until hear death.

The mid-1940s to early 1960s were tumultuous years in South Africa. With the rise of formal apartheid in 1948, racial segregation was intensified.

First’s intrepid and penetrating journalistic research exposed her to the brutality of labour exploitation and control on the mines and the farms. It reinforced her understanding of South Africa in Marxist terms.

She wrote:

Silence in the face of injustice is complicity.

For her:

The will to fight is born out of the desire for freedom.

She was confident that:

The power of the people is greater than the power of any government.

First believed that ignorance is “the enemy of progress and justice” and that knowledge and education are “key to empowering individuals and challenging oppressive systems”. These words ring true in today’s global events driven by right-wing authoritarianism, US imperialism and acts of genocide.

On learning of her death, former South African President Nelson Mandela recalled:

I was in prison when Ruth First was assassinated, felt almost alone. Lost a sister in arms  … It is no consolation to know that she lives beyond her grave.

What is activist research and how is it applied in the book?

As authors, we revisit Ruth First’s life, work and ideas and its relevance for the current context. We focus especially on the nature of her scholarship and how she navigated the tensions between her activism and her research – whether journalistic or for her books on South West Africa (today’s Namibia), Libya or western investment in apartheid. Other of her acclaimed books included The Barrel of a Gun: Political Power in Africa and the Coup d’etat and, during her Mozambican sojourn, Black Gold: The Mozambican Miner, Proletarian and Peasant.

In the process we invite renewed critical reflection about her life and work. Inspired by First’s contributions, the book considers how universities and scholars engage with institutions and social movements beyond the university.

For example, in the book a research group from Durham University in the UK considers how to balance objectivity (showing no bias) with more politically participatory research methods and how objectivity can be enhanced despite the difficulties faced by activist research.

Other scholars reflect on the work of the assassinated South African anti-apartheid activist scholar and lecturer Rick Turner; on climate change; and on the complexities of undertaking activist research in Marikana with a women’s organisation, Sikhala Sonke. Marikana was the site where South African police opened fire on and killed 34 striking mineworkers in 2012.

There is examination of a research partnership between University of Cape Town activist scholars and some Khoi-San communities, reflection on the challenges of legal practice and education, and critical analysis of the decolonisation challenges of the KwaZulu-Natal Society of the Arts.

How do you frame activist research in your book?

The book shows that there is a difference between engaged research, critical research and activist research.

Engaged research tries to connect knowledge produced by academics with institutions, movements and experts outside the university to collaboratively address issues and promote cooperation.

Critical research uses radical critical theory to critique oppression and injustice, to show the gap between what exists today and more just ways of living. However, it does not necessarily connect with political and social movements.

First’s research was not only engaged, but also critical in orientation and activist in nature. As activist research it challenged oppression and inequality.

It both critiqued the status quo in South Africa and elsewhere and tried to change it. It was linked with movements and connected to political activism that was anti-colonial, anti-imperialist, and committed to socialism.

Lessons learnt from taking sides as a sociologist in unjust times


First’s activist research did not confine itself to the academic arena but engaged with larger, wider and more diverse publics. It used this experience to critique dominant and often limited thinking at universities and promoted other ways of producing knowledge. The expertise developed was used to improve scholarship in various ways.

What do you want readers to take away?

There is much talk about the “engaged university” and engaged research. However, only certain connections and engagements seem to be valued.

Prior to democracy in 1994, South African researchers connected with social movements for change. Now this is seldom the case. Universities and scholars largely engage with those with money – the state, business, elites and donors.

Regina Twala was a towering intellectual and activist in Eswatini – but she was erased from history


This raises questions about the roles of researchers in South Africa, whose interests are prioritised and the place of critical and activist research in the engaged university.

How should Ruth First be remembered?

We must honour her for her intellectual and practical activism. What matters is not just her knowledge archive, but also her example as both an outstanding interpreter of the world and an activist scholar committed to changing society in the interests of the downtrodden, marginalised and voiceless.

First was a critical and independent thinker who refused to accept anything as settled and beyond questioning. But that intellect was committed to loyalty to the national liberation movement of which she was an invaluable cadre.

Eco labels in South Africa don’t do the job: how to help customers make informed choices

Source: The Conversation – Africa – By Miemie Struwig, Professor, Department of Business Management, Nelson Mandela University

South Africans want to shop more sustainably, according to research published in the journal Sustainable Development. But most can’t tell which products are environmentally friendly.

Some food manufacturers have introduced eco labels – a certification symbol placed on product packaging. This indicates the product meets specific environmental standards set by a third party organisation.

These labels are meant to signal to consumers that a product has been produced in a way that limits harm to the environment. But our recent study with 108 South African consumers showed low recognition of eco labels, widespread confusion, and a need for clearer guidance.

The results show that most South African shoppers are unfamiliar with these labels or unable to differentiate between real and fictional ones.

In the European Union eco labels like the EU Energy Label are easily understood and highly visible. They are also usually supported by government awareness campaigns. Other examples of labelling systems that work well include those of Germany and Japan.

These countries show that long term institutional support, mandatory labelling in key sectors, and consistent public messaging can greatly improve eco label recognition.

We concluded from our research that South Africa lacks that national visibility and public education, leaving even motivated consumers unsure of what labels to trust. Based on our findings we recommend steps businesses, government and nonprofits can take to ensure that eco labels are clear, visible and understood.

Eco labelling at its best

The EU Energy Label is used on appliances such as fridges, washing machines and light bulbs to indicate their energy efficiency on a scale from A (most efficient) to G (least efficient).

In countries like Germany and Japan, eco labels are government backed as well as being integrated into school curricula, public service announcements and shopping platforms.

Germany’s Blue Angel label, which states “protects the environment”, has been in use since the 1970s. It appears on over 12,000 products and services, including paper goods, cleaning products, paints and electronics, that meet strict environmental criteria. It is supported by ongoing public education campaigns.

In Japan the the Eco Mark appears on products with minimal environmental impact. It appears on items like stationery, detergents, packaging and appliances. Many retailers display explanations next to these products to help consumers understand the label.

South Africans struggle to identify eco labels

We conducted a structured online survey of 108 South African consumers. Participants were asked about their environmental awareness and their ability to recognise both real and fictional eco labels across ten images. According to the global directory of eco labels and environmental certification schemes, there are around 50 eco labels in South Africa.

The EU Energy Label was the most recognised (87%).

The Afrisco Certified Organic label, which is a legitimate South African label, was the least recognised, identified by just 22% of respondents.

Fictional labels were mistakenly identified as real by many participants, revealing widespread confusion.

Only 3 out of 10 labels were recognised by at least half the participants, suggesting a general lack of eco label awareness. These include the Energy Star Eco label; the EU Energy label and the Forest Stewardship council label.

Age and employment status were significantly related to environmental awareness. Older and employed individuals showed higher levels of awareness.

These findings suggest that consumers are not opposed to eco labels, they simply lack the knowledge and confidence to use them effectively.

Eco labels have the potential to build brand trust, drive green purchasing behaviour, and support national sustainability goals. But they only work if consumers recognise and trust them.

In South Africa, inconsistent use, small label size, and a lack of consumer education are holding eco labels back from achieving their purpose.

What businesses can do

Based on our findings, we recommend the following:

  • Use recognised and credible labels: Third-party certified labels are more trustworthy and reliable.

  • Improve label visibility: The most recognised label in our study was the EU Energy Label and was also the most prominent. Small, cluttered logos go unnoticed.

  • Educate your market: Explain what eco labels mean through packaging, marketing, and digital platforms.

  • Partner with government and NGOs: Awareness campaigns at national and community levels can help standardise eco label understanding.

  • Tailor communication efforts: Awareness efforts should consider age and employment demographics, as these affect levels of environmental engagement.

The way forward

South Africans are willing to support environmentally responsible products, but they need help identifying them.

Businesses, government and nonprofits all have a role to play in making eco labels clearer, more visible, and more trustworthy.

Eco labels must become more than symbols. They should be tools for transparency and trust, and a gateway to more sustainable shopping.

Uganda’s ride-hailing motorbike service promised safety – but drivers are under pressure to speed

Source: The Conversation – Africa – By Rich Mallett, Research Associate and Independent Researcher, ODI Global

Motorcycle-taxis are one of the fastest and most convenient ways to get around Uganda’s congested capital, Kampala. But they are also the most dangerous. Though they account for one-third of public transport trips taking place within the city, police reports suggest motorcycles were involved in 80% of all road-crash deaths registered in Kampala in 2023.

Promising to solve the safety problem while also improving the livelihoods of moto-taxi workers, digital ride-hail platforms emerged a decade ago on the city’s streets. It is no coincidence that Uganda’s ride-hailing pioneer and long-time market leader goes by the name of SafeBoda.

Conceived in 2014 as a “market-based approach to road safety”, the idea is to give riders a financial incentive to drive safely by making digital moto-taxi work pay better. SafeBoda claimed at the time that motorcyclists who signed up with it would increase their incomes by up to 50% relative to the traditional mode of operation, in which riders park at strategic locations called “stages” and wait for passengers.

In the years since, the efforts of SafeBoda and its ride-hail competitors to bring safety to the sector have largely been deemed a success. One study carried out in 2017 found that digital riders were more likely to wear a helmet and less likely to drive towards oncoming traffic. Early press coverage was particularly glowing, while recent academic studies continue to cite the Kampala case as evidence that ride-hailing platforms may hold the key to making African moto-taxi sectors a safer place to work and travel.

Is it all as clear-cut as this? In a new paper based on PhD research, I suggest not. Because at its core the ride-hail model – in which riders are classified as independent contractors who do poorly paid “gig work” rather than as wage-earning employees – undermines its own safety ambitions.

Speed traps

In my study of Kampala’s vast moto-taxi industry – estimated to employ hundreds of thousands of people – I draw on 112 in-depth interviews and a survey of 370 moto-taxi riders to examine how livelihoods and working conditions have been affected by the arrival of the platforms.

To date, there has been only limited critical engagement with how this change has played out over the past decade. I wanted to get beneath the big corporate claims and alluring platform promises to understand how riders themselves had experienced the digital “transformation” of their industry, several years after it first began.

Kenya’s ride-hailing drivers say their jobs offer dignity despite the challenges


One of the things I found was that, from a safety perspective, the ride-hail model represents a paradox. We can think of it as a kind of “speed trap”.

On one hand, ride-hail platforms try to moderate moto-taxi speeds and behaviours through managerial techniques. They make helmet use compulsory. They put riders through road safety training before letting them out onto the streets. And they enforce a professional “code of conduct” for riders.

In some cases, companies also deploy “field agents” to major road intersections around the city. Their task is to monitor the behaviour of riders in company uniform and, should they be spotted breaking the rules, discipline them.

On the other hand, however, the underlying economic structure of digital ride-hailing pulls transport workers in the opposite direction by systematically depressing trip fares and rewarding speed.

Under the “gig economy” model used by Uganda’s ride-hail platforms, the livelihood promise hangs not in the offer of a guaranteed wage but in the possibility of higher earnings. Crucially, it is a promise that only materialises if riders are able to reach and maintain a faster, harder work-rate throughout the day – completing enough jobs that pay “little money”, as one rider put it, to make the gig-work deal come good. Or, as summed up by another interviewee:

We are like stakeholders, I can say that. No basic salary, just commission. So it depends on your speed.

We already know from existing research that the gig economy places new pressures on transport workers to drive fast and take risky decisions. This is especially the case for workers on low, unsteady pay and without formal safety nets.

And yet, it is precisely these factors that routinely lead to road traffic accidents. Extensive research from across east Africa has shown that motorcycle crashes are strongly associated with financial pressure and the practices that lead directly from this, such as speeding, working long hours and performing high-risk manoeuvres. All are driven by the need to break even each day in a hyper-competitive informal labour market, with riders compelled to go fast by the raw economics of their work.

Deepening the pressure

Ride-hail platforms may not be the reason these circumstances exist in the first place. But the point is that they do not mark a departure from them.

If anything, my research suggests they may be making things worse. According to the survey data, riders working through the apps make on average 12% higher gross earnings each week relative to their analogue counterparts. This is because the online world gets them more jobs.

But to stay connected to that world they must shoulder higher operating costs, for: mobile data (to remain logged on); fuel (to perform more trips); the use of helmets and uniforms (which remain company property); and commissions extracted by the platform companies (as much as 15%-20% per trip).

As soon as these extras are factored in, the difference completely disappears. The digital rider works faster and harder – but for no extra reward.

Rethinking approaches to safety reform

Ride-hail platforms were welcomed onto the streets of Kampala as an exciting new solution to unsafe transport, boldly driven by technological innovation and “market-based” thinking.

Uganda’s speedy motorbike taxis will slow down for cash – if incentives are cleverly designed


But it is important to remember that these are private enterprises with a clear bottom line: to one day turn a profit. As recent reports and my own thesis show, efforts to reach that point often alienate and ultimately repel the workers on whom these platforms depend – and whose livelihoods and safety standards they claim to be transforming.

A recent investment evaluation by one of SafeBoda’s first funders perhaps puts it best: it is time to reframe ride-hailing as a “risky vehicle” for safety reform in African cities, rather than a clear road to success.

Ghana and India: Narendra Modi’s visit rekindles historical ties

Source: The Conversation – Africa (2) – By Pius Siakwah, Senior Research Fellow, Institute of African Studies, University of Ghana

Narendra Modi’s trip to Ghana in July 2025, part of a five-nation visit, is the first by an Indian prime minister in over 30 years. The two countries’ relationship goes back more than half a century to when India helped the newly independent Ghana set up its intelligence agencies. Ghana is also home to several large Indian-owned manufacturing and trading companies. International relations scholar Pius Siakwah unpacks the context of the visit.

What is the background to Ghana and India’s relationship?

It can be traced to links between Kwame Nkrumah, Ghana’s first president, and his Indian counterpart, Prime Minister Jawaharlal Nehru, in 1957. It is not surprising that the Indian High Commission is located near the seat of the Ghana government, Jubilee House.

Nkrumah and Nehru were co-founders of the Non-Aligned Movement, a group of states not formally aligned with major power blocs during the cold war. Its principles focused on respect for sovereignty, neutrality, non-interference, and peaceful dispute resolution. It was also a strong voice against the neo-colonial ambitions of some of the large powers.

The movement emerged in the wave of decolonisation after the second world war. It held its first conference in 1961 under the leadership of Josip Bros Tito (Yugoslavia), Gamal Abdel Nasser (Egypt) and Sukarno (Indonesia) as well as Nehru and Nkrumah.

The relationship between Ghana and India seemingly went into decline after the overthrow of Nkrumah in 1966, coinciding with the decline of Indian presence in global geopolitics.

In 2002, President John Kufuor re-energised India-Ghana relations. This led to the Indian government’s financial support in the construction of Ghana’s seat of government in 2008.

Though the concept of the Non-Aligned Movement has faded this century, its principles have crystallised into south-south cooperation. This is the exchange of knowledge, skills, resources and technologies among regions in the developing world.

South-south cooperation has fuelled India-Ghana relations. Modi’s diplomatic efforts since 2014 have sought to relaunch India’s presence in Africa.

In recent times, India has engaged Africa through the India–Africa Forum Summit. The first summit was held in 2008 in New Delhi with 14 countries from Africa. The largest one was held in 2015, while the fourth was postponed in 2020 due to COVID-19. The summit has led to 50,000 scholarships, a focus on renewable energy through the International Solar Alliance and an expansion of the Pan-African e-Network to bridge healthcare and educational gaps. Development projects are financed through India’s EXIM Bank.

India is now one of Ghana’s major trading partners, importing primary products like minerals, while exporting manufactured products such as pharmaceuticals, transport and agricultural machinery. The Ghana-India Trade Advisory Chamber was established in 2018 for socio-economic exchange.

Modi’s visit supports the strengthening of economic and defence ties.

The bilateral trade between India and Ghana moved from US$1 billion in 2011-12 to US$4.5 billion in 2018-19. It then dipped to US$2.2 billion in 2020-21 due to COVID. By 2023, bilateral trade amounted to around US$3.3 billion, making India the third-largest export and import partner behind China and Switzerland.

Indian companies have invested in over 700 projects in Ghana. These include B5 Plus, a leading iron and steel manufacturer, and Melcom, Ghana’s largest supermarket chain.

India is also one of the leading sources of foreign direct investment to Ghana. Indian companies had invested over US$2 billion in Ghana by 2021, according to the Ghana Investment Promotion Center.

What are the key areas of interest?

The key areas of collaboration are economic, particularly:

  • energy

  • infrastructure (for example, construction of the Tema to Mpakadan railway line)

  • defence

  • technology

  • pharmaceuticals

  • agriculture (agro-processing, mechanisation and irrigation systems)

  • industrial (light manufacturing).

What’s the bigger picture?

Modi’s visit is part of a broader visit to strengthen bilateral ties and a follow-up to the Brics Summit, July 2025 in Brazil. Thus, whereas South Africa is often seen as the gateway to Africa, Ghana is becoming the opening to west Africa.

Modi’s visit can be viewed in several ways.

First, India as a neo-colonialist. Some commentators see India’s presence as just a continuation of exploitative relations. This manifests in financial and agricultural exploitation and land grabbing.

Second, India as smart influencer. This is where the country adopts a low profile but benefits from soft power, linguistic, cultural and historical advantages, and good relationships at various societal and governmental levels.

Third, India as a perennial underdog. India has less funds, underdeveloped communications, limited diplomatic capacity, little soft power advantage, and an underwhelming media presence compared to China. China is able to project its power in Africa through project financing and loans, visible diplomatic presence with visits and media coverage in Ghana. Some of the coverage of Chinese activities in Ghana is negative – illegal mining (galamsey) is an example. India benefits from limited negative media presence but its contributions in areas of pharmaceuticals and infrastructure don’t get attention.

Modi will want his visit to build on ideas of south-south cooperation, soft power and smart operating. He’ll want to refute notions that India is a perennial underdog or a neo-colonialist in a new scramble for Africa.

In 2025, Ghana has to navigate a complex geopolitical space.

How far is your closest hospital or clinic? Public health researchers explain why Africa needs up-to-date health facility databases

Source: The Conversation – Africa (2) – By Peter M Macharia, Senior postdoctoral research fellow, Institute of Tropical Medicine Antwerp

The lack of reliable information about health facilities across sub-Saharan Africa became very clear during the COVID-19 pandemic. Amid a surge in emergency care needs, information was lacking about the location of facilities, bed capacity and oxygen availability, and even where to find medical specialists. This data could have enabled precise assessments of hospital surge capacity and geographic access to critical care. Peter Macharia and Emelda Okiro, whose research focuses on public health and equity of health service access in low resource settings, share the findings of their recent study, co-authored with colleagues.

What are open health facility databases?

A health facility is a service delivery point where healthcare services are provided. The facilities can range from small clinics and doctor’s offices to large teaching and referral hospitals.

A health facility database is a list of all health facilities in a country or geographic area, such as a district. A typical database should assign each health facility a unique code, name, size, type (from primary to tertiary), ownership (public or private), operational status (working or closed), location and subnational unit (county or district). It should also record services (emergency obstetric care, for example), capacity (number of beds, for example), infrastructure (electricity availability, for example), contact information (address and email), and when this information was last updated.

The ideal method of compiling this list is to conduct a census, as Kenya did in 2023. But this takes resources. Some countries have compiled lists from existing incomplete ones. Senegal did this and so did Kenya in 2003 and 2008.

This list should be open to stakeholders, including government agencies, development partners and researchers. Health facility lists must be shared through a governance framework that balances data sharing with protections for data subjects and creators. In some countries, such as Kenya and Malawi, these listings are accessible through web portals without additional permission. In others, such facility lists do not exist or require extra permission.

Why are they useful to have?

Facility listings can serve the needs of individuals and communities. They also serve sub-national, national and continental health objectives.

At the individual level, a facility list offers a choice of alternatives to health seekers. At the community level, the data can guide decisions like where to place community health workers, as seen in Mali and Sierra Leone.

Health lists are useful when distributing commodities such as bed nets and allocating resources based on the health needs of the areas they serve. They help in planning for vaccination campaigns by creating detailed immunisation microplans.

By taking account of the disease burden, social dynamics and environmental factors, health services can be tailored to specific needs.

Detailed maps of healthcare resources enable quicker emergency responses by pinpointing facilities equipped for specific crises. Disease surveillance systems depend on continuously collecting data from healthcare facilities.

At the continental level, lists are crucial for a coordinated health system response during pandemics and outbreaks. They can facilitate cross-border planning, pandemic preparedness and collaboration.

During the COVID-19 pandemic, these lists informed where to put additional resources such as makeshift hospitals or transport programmes for adults over  60 years of age.

The lists are used to identify vulnerable populations at risk of emerging pathogens and populations that can benefit from new health facilities.

They are important when it comes to making emergency obstetric and newborn care accessible.

What goes wrong if you don’t have them?

Many problems arise if we don’t know where health facilities are or what they offer. Healthcare planning becomes inefficient. This can result in duplicate facility lists and the misallocation of resources, which leads to waste and inequities.

We can’t identify populations that lack services. Emergency responses weaken due to uncertainty about where best to move patients with specific conditions.

Resources are wasted when there are duplicate facility lists. For example, between 2010 and 2016, six government departments partnered with development organisations, resulting in ten lists of health facilities in Nigeria.

In Tanzania, over 10 different health facility lists existed in 2009. Maintained by donors and government agencies, the function-specific lists didn’t work together to share information easily and accurately. This prompted the need for a national master facility list.

What needs to happen to build one?

A comprehensive list of health facilities can be compiled through mapping exercises or from existing lists. The health ministry should take responsibility for setting up, developing and updating this list.

Partnerships are crucial for developing facility lists. Stakeholders include donors, implementing and humanitarian partners, technical advisors and research institutions. Many of these have their own project-based lists, which should integrate into a centralised facility list managed by the ministry. The health ministry must foster a transparent environment, encouraging citizens and stakeholders to contribute to enhancing health facility data.

Political and financial commitment from governments is essential. Creating and maintaining a proper list requires significant investment. Expertise and resources are necessary to keep it updated.

A commitment to open data is a necessary step. Open access to these lists makes them more complete, reliable and useful.

The first fossil thrips in Africa: this tiny insect pest met its end in a volcanic lake 90 million years ago

Source: The Conversation – Africa (2) – By Sandiso Mnguni, Honorary Research Associate, University of the Witwatersrand

Thrips are tiny insects – their sizes range between 0.5mm and 15mm in length and many are shorter than 5mm. But the damage they cause to crops is anything but small. A 2021 research paper found that in Indonesia “the damage to red chilli plants caused by thrips infestation ranges now from 20% to 80%”. In India, various thrips infestations in the late 2010s and early 2020s “damaged 40%-85% of chilli pepper crops in Karnataka, Andhra Pradesh and Telangana”.

In Africa, a number of thrips species feed on sugarcane and have been known to damage nearly 30% of the crop in a single hectare of a farm. High rates of destruction have been recorded in Tanzania and Uganda on onion and tomato crops.

Now it’s emerged that thrips are hardly new to the African continent and the southern hemisphere more broadly. South Africa’s first and only Black palaeoentomologist, Sandiso Mnguni, who studies fossil insects, recently described a fossil thrips from Orapa Diamond Mine in Botswana that’s more than 90 million years old. He discussed his unique fossil find with The Conversation Africa.

What are thrips and how do they cause damage?

Thrips, also known as thunderflies, thunderbugs or thunderblights, are small, slender and fragile insects. They can be identified by their typically narrow, strap-like, fringed and feathery wings. Over time, they have also evolved distinctive asymmetrical rasping-sucking mouthparts consisting of a labrum, labium, maxillary stylets and left mandible. Most species use these to feed primarily on fungi. Some feed on plants and eat the tender parts of certain crops like sugarcane, tomatoes, pepper, onions, avocado, legumes and citrus fruits, focusing on the buds, flowers and young leaves.

This, along with their habit of accidentally distributing fungal spores while feeding or hunting, makes them destructive crop pests. They tend to feed as a group in large numbers, causing distinctive silver or bronze scarring on the surfaces of stems or leaves.

However, not all thrips are harmful. A small fraction of the 6,500 species that have already been described so far are pollinators of flowering plants; and a handful are predators or natural enemies of moths and other smaller animals such as mites.

Tell us about the fossil thrips you’ve discovered

This is the first time that a fossil thrips has been recorded anywhere in Africa – or the entire southern hemisphere.

The Orapa Diamond Mine in Botswana is one of the most important fossil deposits on the continent. It’s about 90 million years old, dating back to the Cretaceous period.

The deposit is situated 960 metres above sea level in the Kalahari Desert, about 250km due west of Francistown in Botswana, and 824km away from Johannesburg in South Africa. It was first discovered in 1967 and started producing carat diamonds in 1971.

Roughly 90 million years go, steam and gas caused a double eruption of diamondiferous kimberlites. These are vertical, deep-source volcanic pipes that form when magma rapidly rises from the Earth’s mantle, carrying diamonds and other minerals up to the surface. They create a distinctive rock formation that gets studied by geologists. This explosive volcanic eruption formed a deep crater lake at the centre of the mine.

Mining excavations during the 1980s and earlier uncovered and exposed fine-grained sedimentary rocks containing well preserved fossil plants and insects. These have already been studied by many researchers in the past. At the time, geology and palaeontology researchers from what was then the Bernard Price Institute, which has since been renamed the Evolutionary Studies Institute, at the University of the Witwatersrand in Johannesburg, were invited to collect the fossil material.

Although some of the material has been studied in the past, the fossil thrips hadn’t yet been put under the microscope. And that’s just what we did. By using its body characteristics and comparing it to living thrips, we can say for sure that it’s a thrips. But we didn’t give it a formal scientific name because it doesn’t have enough characteristics to classify it at the species level and describe it either as a new species or one that still exists today.

We think that the thrips either flew into the palaeolake that was formed by the volcanic eruption or was transported there through grass from a bird’s nest.

Why is this useful to know?

This discovery sheds light on the biodiversity and biogeography of thrips and many other groups of insects during a time when we know flowering plants that heavily relied on insect pollination were rapidly diversifying. This plant-insect reciprocal interaction goes back to the Devonian period, a time when there was a large super-continent called Gondwana. That’s when the first land plants evolved and dominated the Earth, and inadvertently led to many groups of insects, including thrips, diversifying to keep up with drastic changes in their preferred plant diets and habitats due to the dramatic environmental and climatic changes.

The fossil find also contributes to a more accurate documentation of life on Earth during the Cretaceous and helps scientists in reconstructing the past environment and climate in Botswana.

Hopefully there are more fossil insects waiting to be discovered in Botswana and elsewhere in Africa, to keep improving our picture of this long-ago world, and preserve the heritage of our continent.

Dinosaur tracks, made 140 million years ago, have been found for the first time in South Africa’s Western Cape

Source: The Conversation – Africa (2) – By Guy Plint, Professor Emeritus, Earth Sciences, Western University

Dinosaurs have captured people’s imagination ever since their bones and teeth were first scientifically described in 1822 by geologist and palaeontologist Gideon Mantell in England.

Dinosaur bones have taught us a great deal about these animals from the “age of dinosaurs”, the Mesozoic Era, which stretched from approximately 252 million years ago to 65 million years ago. However, there’s something especially appealing about a different kind of dinosaur fossil: their tracks, which show researchers what the animals were doing while they were alive.

Ichnology is the study of tracks and traces and, since 2008, the Cape South Coast Ichnology Project has documented more than 370 vertebrate tracksites on South Africa’s southern coast. These sites are from the Pleistocene Epoch, which stretched from approximately 2.6 million years ago to 11,700 years ago, much more recent than the Mesozoic.

We knew that this coastline contained Mesozoic sedimentary rocks, some of which include non-marine sediments that could potentially preserve dinosaur tracks. We are both familiar with dinosaur tracks from our research in Canada, so we decided to investigate the possibility of tracks in South Africa’s Western Cape.

We found some – and, once we knew what to look for, it was evident that the tracks were not rare. In a new paper published in the journal Ichnos, we describe our findings in detail, presenting evidence of tracks of sauropods (enormous plant-eating dinosaurs) and possibly ornithopods (another group of large herbivorous dinosaurs).

The tracks were found in a rugged, remote, breathtakingly spectacular coastal setting. They were made by dinosaurs in a variety of estuarine settings. Some were walking on sandy, inter-tidal channel bars. Others walked on the bottom of tidal channels, their feet sinking down into soft mud forming the bed of the channel. Other vague “squishy” structures were formed by dinosaurs wading, or even wallowing in the muddy fill of abandoned channels.

These tracks are around 140 million years old, from the very beginning of the Cretaceous period when the African and South American tectonic plates were starting to pull apart. Southern Africa has an extensive record of Mesozoic vertebrate fossils, but that record ends at around 180 million years ago in the Early Jurassic with the eruption of voluminous lava flows. To the best of our knowledge, all the southern African dinosaur tracks known until now are from the Triassic and Jurassic periods, so they pre-date these eruptions.

That means these tracks are not only the first from the Western Cape. They also appear to be the youngest – that is, the most recent – thus far reported from southern Africa.

Knowing where to look

After deciding to hunt for potential dinosaur tracks, we visited a few likely sites on the Cape south coast in 2022, choosing areas with non-marine deposits of the appropriate age, mostly in the eastern coastal portion of the Western Cape. We found a few promising spots on that visit and, in 2023, undertook a dedicated examination.

Large horizontal bedding surface exposures in this area are very rare. We knew that, if we were to find dinosaur tracks, they would be evident mostly in profile in vertical cliff exposures.

Footprints take science a step closer to understanding southern Africa’s dinosaurs


In the public imagination a dinosaur trackway extends across a level surface and toe impressions are visible. Some may also know that the infill of dinosaur tracks can occur on what are today the ceilings of overhangs or cave roofs. However, there are also distinctive features that allow tracks to be identified in profile. That’s because the animals’ footfalls deformed underlying layers in a distinctive manner.

The problem is that other mechanisms, such as earthquakes, are capable of generating broadly similar deformation structures.

The deposits we were examining had probably also been affected by seismic activity. The challenge was for us to differentiate between the two types of deformation.

The Early Cretaceous rocks that we examined had been studied and reported on decades ago, and the deformation structures had been attributed to origins such as earthquakes rather than living organisms. Since then, however, scientists have developed a better appreciation of what dinosaur tracks look like in profile.

After careful examination, our conclusion was straightforward: both dinosaur-generated and earthquake-generated types of deformation were present in the Cretaceous rocks.

Further evidence that we were looking at dinosaur tracks comes from the region’s bone fossil record. Cretaceous bone material has been reported from the region, mostly in the Kirkwood area in the Eastern Cape province. Two dinosaur bones have also been reported from the Knysna area in the Western Cape. One of these, a theropod tooth, was found – and correctly identified – by a 13-year-old boy.

Clearly, dinosaurs were present in the Western Cape area. That means our discovery of ichnological evidence of their presence is not entirely surprising, but it is still extremely exciting.

Keep exploring

Our team plans to keep exploring deposits of suitable age in the region for evidence of more dinosaur tracks. We also hope that our discovery will inspire a new generation of dinosaur trackers to continue the quest and keep exploring.
