Africa is the fastest growing continent, according to McKinsey. By 2025 there will be 100 African cities with more than one million inhabitants. This urban growth will require enormous amounts and movements of construction materials, which in return will coin economic growth on the one hand along with ecologic impact on the other hand. It is therefore important to plan and build the expansion of cities with sustainability at the forefront. Incorporating local materials into the supply chain can create livelihoods, the availability of space and resources offers opportunities to create socio-economically responsive urban regions that can be future-oriented without losing tradition and cultural heritage. Through the lens of sustainable materials, structures and designs we can create more environmentally friendly materials, healthy and liveable cities. Sustainability in the context of urbanisation allows for innovative, reinvention and restoration of past and current solutions to evolving urban problems.

In the past, gender aspects have been neglected out of development debate, hence it is crucial to have intersectional solutions when we engage in sustainable development discourse. There is still a huge disparity in the representation of women in STEM fields across the world not just in Africa. In sub-Saharan Africa only 31.3% of women are in employed in Research and Development positions and of which most are in lower positions and have limited decision-making power. There is a need to have inclusive solutions that will ensure the success of women in STEM and achieving sustainable developments. 


The Seminar “Aspects of Materials, Architecture, Structures and Gender Equity in Sustainable Urban Development in Africa” gathers high-level experts from materials, architecture and sciences who will give insights on sustainable urbanisation with a focus on to sustainable materials, architectural and structural solutions, as well as gender considerations.


The seminar takes place with the financial support of Programme Advocating Women in STEM (PAWS) by the German Ministry of Education and Research ( The scientific content has been approved by the RILEM Educational Activities Committee (

FALCONESS Kick-off meeting in Accra

Between 20 and 24 September the FALCONESS Kick-off meeting will take place. Despite the difficult times, it was possible to organise a joint meeting of the project group as well as external experts who can contribute to the discussions.

The one-week workshop will be held at Hillburi, Aburi. The first day is dedicated to technical issues. On the second days, a student seminar will be held at the University of Ghana followed by an Accra architectural and urban development tour. The third day will be a full interactive workshop day with the aim to better specify the challenges and potentials of female African researchers within the Built Environment. In the last day of the workshop, homework will be distributed, so that a fruitful follow up workshop can be organised between 11 and 15 October in Berlin.

African gender brainteaser or why African women always seem to be smarter than their male counterparts

I’ve been blessed to see quite a number of countries and places on the African continent. Being in contact with so many different cultures and being able to learn from it is a blessing in itself. And getting a deeper insight in the incredibly diverse richness of African cultures, histories, and social interactions, which can impossibly be obtained from the unilateral information that can be distilled from European media, is extremely eye opening. Still today, most Europeans do perceive Africa as a country in which people and cultures are more or less the same. People are really not to blame for this perception, as it is really based on the very limited information about Africa that can be received from the popular media. In 2014, I analysed the media in Germany for what they reported about Africa, and the only news I found were all about Al-Shabab, Boko Haram, and Oscar Pistorius, thus, exactly what people in Europe like to hear about in Africa: war, terror, and crime. What was missing at that time were hunger and drought, which are the parameters that typically supplement the picture we like to draw of the “African country” in Europe.

However, the reality is certainly quite different: much more positive, and definitively much more diverse. If you have ever travelled from Dar es Salaam to Accra, you know that Africa is definitively not a country, and cultures, people, ways of living are much more different than between most of the European countries. A few things, however, and despite the incredible diversity that can be observed in Africa, to me always seemed to re-appear no matter whether I was in Central, Eastern, Western or Southern Africa. One was the always extremely positive impression I had of the women I met in academia, researchn and decision making positons.

I was lucky that in most of my projects with African partners I met a few of the most inspiring (often quite young) people of both gender. I met brilliant female and male students, researchers, lecturers and decision makers. However, everytime I flew back and reflected upon my trip, I wondered why I was left with the retrospective feeling that “somehow the women seemed to be smarter than their male counterparts“, despite the fact that the brilliant people I met were equal in number of men and women. In fact, I was puzzled about this perceicved contradiction for a long time, until I tried to look at it from a purely analytical perspective that excludes the idea that there are specific male or female performances.

Indeed, the number of brilliant male and female personalities I met was equal for both gender, but in total I met significantly more men than women. The professional networks in most African societies are heavily male dominated. This means there is a great permeability for men, regardless of their talent. Access to certain positions is rather granted based on family relations, existing networks or personal relations to the employer than based on skill. For women, the access is restricted, and only those whose talent stands out so much that it overcompensates the perceived gender disadvantage can have a chance at all. This means, in a certain position, if you meet a man, he can be really excellent but he could also just be the lazy son of an influencial person. A women in the same position is automatically brilliant with a much higher probability, because if she weren’t she would not be in this position.

In other words, I met very talented men but also a high number of less talented men, but I mostly met only very talented women. And this is not because the less talented women do not exist. They do; in the same percentage as for men, but unlike the men, they are not given a chance to participate. The mathematics behind are explained here. It is also shown, why the inclusion of more women automatically (and purely statistically) causes enhanced performance of men.

It is a simple question of who will be included and who will be excluded in networks. The logic behind is not limited to gender aspects, it is just most visible for women and men. Basically, the exclusion of any group of people in a society causes the same effect, may it be for reasons of religion, age, sexuality, gender or colour of skin. The result of exclusion is that more of the less talented individuals are included in societal activities, while the more talented are not given a voice.

In the light of the climate change, pressing global challenges related to resource depletion, rapid population growth, urbanisation, and societal unrest, no society in the world can afford anymore to exclude their most skilled and innovative talents. These talents are equally distributed among men and women, and people need to understand that the exclusion of talents automatically weakens societies. This, should not be any human’s or society’s future perspective, regardless of the gender, and that is why also every man should fight for the inclusion of women.

Disrupting the status quo: Science edition

By Nonkululeko Radebe

To whom does science belong?

It has proven to be quite a challenge to write a comprehensive essay about dismantling or disrupting the status quo in science. I suppose to tackle the issue one has to possess some knowledge about the existing state of affairs in science. Firstly, what does a scientist look like? What is the most represented version of a scientist? Why does this matter? Once we have answered these questions then perhaps, we can explore how and why different people with diverse backgrounds relate differently to science. One of the ways in which we can do so is look at the education systems and curricula in different communities and investigate whether or not they allow science to be accessible to all and contextualized. We need to get rid of the eurocentric dominance and eurocentric hegemony of

It is no secret that African values, perspectives, contributions and experiences are not prioritized in science. Indigenous African science, although not mainstream, is still science. Veteran science journalists Sarah Wild and Linda Nordling share that “there is a wealth of traditional knowledge systems in Africa, but the current global science system came to Africa in the hands of the colonialists. Modern research centres in Tanzania, Cote d’Ivoire and Zimbabwe have their roots in medical or agricultural science outposts funded and manned from their colonial masters” (1). This introduces the issue of research funding. Much of the funding for masters and Ph.D. studies comes from external donors whose real interest do not align with those of the people on the local people. Some of the top ranked universities in Africa have research groups researching telescopes, robots, and accelerated mass spectrometers etc. and have no immediate relevance to African people. In South Africa, we have the National Indigenous Knowledge Systems Office within the Department of Science and Technology, the main driver of science within government. One of the objectives if the Indigenous Knowledge Bill is to “develop and enhance the potential of indigenous communities to protect their indigenous knowledge” (2). Billions of rands have been spent on researching indigenous knowledge, such as medicinal plants but the National Research Foundation (NRF) can certainly do more to ensure that funding is provided to projects that have lasting impact on the lives of people in the country. Having said
that, we also need to recognize that science has been developed by knowledge from all around the world. Science does not have a so called “origin”. We are collective agents of the history and the future of science.


Furthermore, we need to address the issue of physical representation in science and research. Math and science have always been, and is still, considered “masculine subjects” because they involve logic and numbers, which apparently “emotional females” cannot handle. Of cause, we cannot solely blame this stereotype on the education system but on society as a whole. How can we expect young girls to aspire to be game changers, engineers, scientists to be innovators when they are brought up playing with gender-based toys? Young boys are stimulated with train sets and Lego to build with as well as chemistry sets to discover with whist young girls are given make-up sets and dolls. We need to encourage and inspire young girls and what better way than sharing with them scientific breakthroughs and achievements by women. Achievements by of women in science both in the history book and in the present day have been overlooked and representation of women is disproportional to say the least. Although someone like Marie-Curie (Nobel laureate for discovering the radioactive elements polonium and radium) (3) often dominates the conversation when it comes to brilliant female scientists but it is important to point out that there were exceptional women contributors to science before and after her, yet most of them were snubbed due to sexism. One of these women was Rosalind Franklind, who was a biophysicist that studies DNA and contributed to the discovery of the structure of DNA (4). For this research, two of her male colleagues went on to win the Nobel Prize. In addition, in a recent screenplay called “Hidden Figures” we learn that African-American female mathematicians, during the height of segregation and oppression, beat the odds and formed part of the team that calculated the launch of astronaut John Glenn into orbit, and guaranteeing his safe return (5). This is important for young girls, young girls from all ethnicities to see and hear. It is most especially necessary to begin and decenter white, heterosexual, and middle or upper class men from being the face of science. The system will not reform itself only through historiography. If we really want pragmatic change, we need to have serious conversations with those in institutional governance, those who make and implement policies. What would make this deal even sweeter would be if the boardrooms in which these decisions are made actually had women in them because “you can’t make decisions, if you are not in the room where the decisions are being made”-Unknown. The smartest move is to invest in women and continue to make deliberate and systematic changes to boost the number of females in lower and higher education through scholarships, science expos in rural areas that may not have access and increasing scientific resources that will improve the quality of education.

How to “science” 101

Whilst we invest in young girls and women, we should also consider ways in which we give tangible meaning to science. A great start would be to demystify science by allowing children in at primary school level to solve real problems with solutions they think of together. This same idea was beautifully illustrated in a TED talk titled “How to teach kids to love science”. In this TED talk the speaker, Cesar Harada, explains how he teaches invention and citizen science at the Hong Kong Harbour School. He moved his classroom into an industrial mega-space where imaginative kids work with wood, metal, chemistry, biology, optics and, occasionally, power tools to create solutions to the threats facing the world’s oceans. The classroom has been transformed into a workshop where the kids, which range in age from 6-15, do rapid prototyping. One of the projects they did was to build a sensor that would estimate the about of plastic found in the ocean. The kids then found a community with other kids that needed this technology to identify the amount of oil in their water (from an oil spill). They shipped they robot sensor, in this small but significant way showed empathy, and were able to help another community (6). Furthermore, by doing this, he and the students has destroyed the notion that science is practiced only in a laboratory. Science is being “done” every day and everywhere. The irony is that science is seen as somewhat as a conservative sphere all though science bring different disciplines together.

Embracing interdisciplinary learning

I often come across stories about young men and women, in rural areas, who are purifying water through traditional and household purification methods and generate electricity for their families using solar energy. That is innovation and that is science. Fact is, necessity has always been the driving force behind innovation and homemade purification system and electricity generators are testimony to that. This also reiterates that scientific change should be recognized only at a contextualized level of description of the practices of scientists at rather specific times and places. Currently, there is not enough energy being extracted from known sources of fossil fuels to sustain an estimated 7.5 billion people (7). This means that humans will be forced to turn to a new energy sources before the end of the century. However, necessity has proven to be the catalyst needed for innovation and currently we are in need of clean drinking water, housing and sustainable farming for food. We need plans for sustainable farming, and cheaper ways to turn seawater into drinking water. Contrary to popular belief, I think that migrating towards clean energy should not take us decades. Clean energy sources such as wind, solar, geothermal, and tidal kinetic power already exist and that application of these methods should be expanded and implanted worldwide. Already in some countries, the move away from cars that run on gas towards electrical cars has been made. The next step would be to a smart electrical grid, and invest in carbon-capture. This highlights how science can be used and in fact has been used as pivotal part in building the economy, technological advances and societal progress. Furthermore, it will prove to be more effective if more interdisciplinary relationships are built between science, engineering, commerce and social science. As much as new technology is necessary, large-scale changes can be made through policy changes more than gadgets and more often than not, people who are in commerce and social science are the policy makers and allocate government funding.

In Conclusion

It is obvious that factors of community, society, gender and technology play a key role in facilitating or mitigating scientific change. We have to explore the challenges that we are faced in our respective communities whether that be our immediate, remote or global communities. Thereafter we need to place more effort into investing in women to study science through deliberate systematic changes. Further, we have to apply local solutions for local problems with the influence of indigenous knowledge and an interdisciplinary approach. The changing global environment is not only a natural sciences issue but very much a social sciences issue too. This means solutions that combine socio-political, cultural and economic (8) are needed. The most effective relationships in these fields can be fostered through sharpening the efforts to improve access and quality of education. Science, in my humble opinion, is most effect when we pull away from intellectualizing it but instead applying it to improve the lives of earth’s inhabitants.
