UFS BRICS-PLUS tackles global challenges
Dr Thulisile Mphambukeli (UFS), Dr Fidelia Dake (University of Ghana), and Dr Victor Okorie (UFS).
Over 70% of the earth is water yet more than two billion people lack access to clean water and sanitation. About 795 million people are food insecure but one third of all food produced in the world, which worth $1.6 billion, is thrown into the dustbin every year. These are the problems, the paradoxes, which seasoned social scientists, engineers and clinicians from universities, research institutions and non-governmental organisations in South Africa, Russia, India, Ghana, Nigeria, and Zimbabwe deliberated at the BRICS-PLUS conference.

The scholars also noted that the grim statistics of water and food-related human suffering, including illnesses, are on not only the increase but overweight and underweight now co-exist in the same household. Dr Victor Okorie, a Postdoctoral Fellow and Dr Thulisile Mphambukeli, a senior lecturer at the Department of Urban and Regional Planning at the University of Free State (UFS), along with Prof Lere Amusan of the North-West University, successfully hosted the first BRICS-PLUS Conference themed: Water, Food and Health Nexus in BRICS-PLUS: Problems, Progress and Prospects were the topics discussed.

The delegates collectively identified some drivers of the problematic paradoxes: including accelerated climate change, urbanisation, inequality, inequity, and population growth. Others were a move from family to factory food and limited physical activity, among other unhealthy lifestyles.

Recommendations based on observation

After the delegates deliberated on various issues of water, food and health nexus in BRICS-PLUS, they made the following policy recommendations:
• There should be strong collaboration among critical stakeholders such as the state, civil society and knowledge institutions with respect to reducing the challenges of water, food and health.

• Issues of gender and the youth should be explicitly incorporated into policies guiding water, food and health nexus across BRICS-PLUS.

• The BRICS-Plus research team should be upgraded into a more permanent organisation in order to strengthen how it deals with the challenges at hand.

• There is a need to balance competing uses of water and other natural resources to prevent further pollution and destruction of the commons.

• Investments in research on water, food and health to generate innovations for sustainable development should inform BRICS’ science, technology and innovation agenda.

• There is a need to promote a zero-waste circular economy through recycling in production, preservation, processing, more equitable distribution and consumption processes to reduce ecological footprints across BRICS-PLUS, and generate energy for sustainable economy.

• It’s necessary to encourage technology transfer, capacity-building and policy learning among member-states

• BRICS should encourage favourable terms of trade among member states with respect to water, food and health issues.

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
