Water management reseachers
Marinda Avenant, Dirk Jungman and Niels Schütze are working on a project proposal for a decision support system that will assist local authorities with sustainable water resources management. Both Dirk and Niels are from the Technical University Dresden in Germany.

Climate change has a strong effect on the water cycle and is likely to lead to a multitude of hazardous weather events such as droughts, heavy rainfall and floods in Southern Africa.

The Technical University of Dresden, in Germany, in collaboration with the Centre for Environmental Management at the University of the Free State (UFS), earlier this year received seed funding to develop a project proposal for a study on the risks of climate change.

At a recent workshop, universities (including the Central University of Technology, University of KwaZulu-Natal, University of Pretoria, Cape Peninsula University of Technology and the Namibia University of Science and Technology), Weather SA and the Global Water Partnership of Southern Africa) as well as companies from the public and private sectors and universities in Germany (Technical University Dresden, United Nations University Flores, Büro für Angewandte Hydrologie, and WISUTEC Chemnitz), collaborated to discuss the project proposal.

The proposal to obtain funding for the study will be submitted in May 2019.

 

Managing water resources

Once funding is obtained, the combined team will study a series of sites in the upper (Qwaqwa), middle (Free State Goldfields) and lower Vaal catchment areas. The aim of this three-year project is to prepare climatic, hydrological and ecological models as a basis for the development of a decision support system (DSS). This simple-to-use DSS is intended to assist local authorities with sustainable water resources management, as well as to address the risks associated with future climate change in their regions.

The study is titled: Threats of droughts and floods: investigating resilience to the multiple risks of climate change in Southern Africa and the study area was chosen for its suitability in terms of non-perenniality of rivers, residual impacts of mining, climate change, urbanisation, the poor quality of water, major modification of natural ecosystems, as well as poverty and joblessness.

According to Marinda Avenant, lecturer in the Centre for Environmental Management, increasing hazards can result in additional ecological, social and economic impacts and risks such as asset damage, yield reduction and decrease of livelihoods for the region. “We intend to produce a tool to support decision-making and risk-management by means of easily understandable guidelines to consider threats of droughts and floods under climate-change conditions of mining-contaminated, non-perennial river systems,” said Avenant.

 

Reliable forecasts

 

A web-based data platform to provide reliable forecasts of disaster risk and effective warnings of multiple hazardous weather events will also be developed to support resilient management strategies and to trigger risk reduction behaviour.

The University of the Free State’s Faculty of Health Sciences hosted the annual Hannes Meyer Symposium in Cardiothoracic Surgery. The symposium was organised by Prof Francis Smit, head of the department of Cardiothoracic Surgery at the UFS, with the support from the Society of Cardiothoracic Surgeons of South Africa and the European Association of Cardiothoracic Surgery (EACTS). Over the past 16 years this symposium has steadily been growing in stature and prestige leading to the resounding success that was this year’s event.

Medical advancements explored
The aim of the symposium is to provide an overview of the latest advances in Cardiothoracic Surgery and perfusion as well as providing hands-on training via simulation to trainees from South Africa and the rest of the African continent. Didactic lectures and papers by registrars were an integral component of the symposium. The South African community was represented by various heads of departments, trainees, senior specialists and perfusionists from all the training centres in the country. There were also delegates representing Uganda, Mozambique, Nigeria and Zambia.

Heart surgery off to new heights
Simulation in Cardiothoracic Surgery and Perfusion can be compared to airline pilots with high risk, with complex surgeries being first done in simulators before being attempted in the real world. The UFS is proud to have a state-of-the-art simulation facility, which was used to facilitate the programme.

The range of simulation was extensive and included simple procedural models to complex full theatre setups with Human Performance Models in perfusion that simulated crisis scenarios with the aid of computerised devices that react in real time to human intervention.

Industry support highly appreciated
This event was coordinated by Dr Jehron Pillay, senior registrar in the Department of Cardiothoracic Surgery and Marilee Janse van Vuuren, deputy-director clinical technology, in the department. This was the first time that such extensive simulation models were used in the programme and judging from the positive response received, it has certainly set the benchmark for all future events.

The event has received invaluable support over the years from EACTS that has selected Bloemfontein as the site of its African training programme as a result of the high level of training and education achieved here.

The academic discussions were chaired by Profs Marko Turina and Jose Pomar (past presidents of EACTS) and Pieter Kappetein (past secretary general of EACTS) who are extremely well known internationally for their contribution to advancing Cardiothoracic training and education.

Our guests from EACTS presented didactical lectures on research methodology, international randomised trials and discussed recent developments and controversies in cardiothoracic surgery.

Registrars from all South African units presented a thoracic and cardiac surgery paper from each unit highlighting specific disease conditions, moderated by heads of departments and the international panel.

An event of this magnitude requires significant financial support and the medical industry in South Africa stepped up to the plate in providing financial and logistical support in order to make it possible.
