Prof Francis Petersen, Rector and Vice-Chancellor of the University of Free State, South Africa, invites us to rethink our relationship with the world in a series of ‘Courageous Conversations’ on the theme of ‘The Global Citizen’. Prof Petersen argues that COVID-19 has been a powerful ‘disruptor’ – it was a stark reminder of the need to rethink our identity, of where we belong, our ‘normative’ view of citizenship – if we want to secure long-term survival of our civilisation and the environments that support it.

Global citizenship and the Sustainable Development Goals – 30 July 2021, 13:00 SAST

Join us for the next Courageous Conversation in the Global Citizen series when Prof Petersen will welcome eminent economist, professor at Columbia University, Director of its Earth Institute, and global leader on sustainability, Prof Jeff Sachs.
 
In 2015, almost all countries signed up to the UN Sustainable Development Goals (SDG). This commitment marked an international solidarity of virtually all countries to work towards the betterment and development of every person on earth. Then COVID-19 struck. Not only did the crisis result in a retrogression of successes registered in achieving the SDG, most notably in the reduction of global poverty, but it also exposed global power disparities.
 
In this session, Prof Sachs will discuss global citizenship and the SDGs in the context of recovery from the COVID-19 pandemic, including what an equitable recovery would mean for countries around the world, and will make reference to the 75th anniversary of the Universal Declaration of Human Rights.

Prof Sachs is widely recognised for addressing complex global challenges such as debt crises, hyperinflation, the control of AIDS, malaria, poverty, and climate change, among a myriad of others.

Sachs serves as the Director of the Center for Sustainable Development at Columbia University. He is President of the UN Sustainable Development Solutions Network, a commissioner of the UN Broadband Commission for Development, and an SDG advocate for UN Secretary General, Antonio Guterres. From 2001 to 2018, Sachs served as Special Adviser to UN Secretaries-General Kofi Annan (2001-2007), Ban Ki-moon (2008-2016), and António Guterres (2017-2018). 


A world-renowned economics professor, bestselling author, innovative educator, and global leader in sustainable development, Sachs was the co-recipient of the 2015 Blue Planet Prize, the leading global prize for environmental leadership. He has twice been named among Time Magazine’s 100 most influential world leaders and has received 34 honorary degrees. A survey by The Economist ranked Sachs as among the three most influential living economists.
 

The Global Citizen Courageous Conversations series

In partnership with the South African Chamber of Commerce based in the United Kingdom, the Global Citizen Courageous Conversations series that was launched on 26 May 2021, brings together powerful voices from public life, intellectuals, public interest and business leaders, academics, naturalists, religious leaders, astrophysicists, economists, ecologists, and others.

Eminent South African business leader, Prof Bonang Mohale, joined Prof Petersen for our first Courageous Conversation on 17 June 2021 to unwrap the role that universities can play in creating a ‘global citizen’ mindset to effect material change in a constantly evolving and turbulent international world.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
