The body of a sixty-year-old homeless man is discovered in a tent on the outskirts of Canterbury, Kent, UK. Cursory research reveals that he had been refused a place on the council’s housing register and that he was a former member of the British armed forces – a group that makes up close to a quarter of the ‘rough sleepers’ in London. This raises questions about the complex relationship of politics, campaigning, gender, and welfare in homelessness law, policy, and practice.

Jump across the Atlantic Ocean to Klapmuts, Western Cape, South Africa, where beneficiaries of an RDP housing project are benefiting from the shelter provided in the form of private home ownership. Yet, they are not using these assets to its full potential, e.g. as security for credit to start or expand a business. This raises questions about whether the less expensive route of providing public housing with tenure security would not be a better option.

International workshop on housing

Diverse issues such as these came up for discussion as planners, geographers, architects, art historians, social activists, and lawyers recently met during a workshop at the University of the Free State to discuss what a home constitutes, and how best to provide and protect homes in a sustainable and inclusive manner in 21st century cities. The workshop was hosted by the Free State Centre for Human Rights on the Bloemfontein Campus.

Participants presented papers and engaged in discussions on home-related topics as diverse as Hannah Arendt’s conception of the intimate and political spheres; Henri Lefebvre’s notion of a right to the city; alternative, environmentally conscious building methods; court cases dealing with the concept of home; the right to a domestic garden as a component of the right to a home; and constructing the home as a subversive and empowering alternative when it comes to giving birth.

Going forward

The same group of participants will meet for a follow-up workshop at Kent University in the UK in February 2019, and a third workshop in Belo Horizonte in Brazil in June 2019, with the project culminating in the publication of an inter-disciplinary book containing the papers workshopped at the three events.

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.
