A Brazil, Russia, India, China and South Africa (BRICS) delegation is to hold the 10th Annual BRICS Summit in the last week of May 2018 in Johannesburg. Dr Thulisile Mphambukeli, leader of the University of the Free State (UFS) research team alongside Dr Victor Okorie from the Department of Urban and Regional Planning, in collaboration with Prof Lere Amusan of North-West University, will ensure that water and food security is a prominent feature on the gathering’s agenda.

First, the project titled: “Exploring the political economy of water and food security nexus in BRICS and Africa” will debut at the National Institute for the Humanities and Social Sciences BRICS Think Tank Forum”.

According to Dr Mphambukeli, the key to water security is attitudinal change by means of education and conscientisation. This, she is adamant about, holds the potential to drive behavioural adjustments in the way society interacts with water.

Genetic and social approaches
Dr Okorie asserts that if strides towards reducing the demand for water were to be made, research efforts should be geared towards effecting changes at DNA level. Meaning we need to explore waterwise ways that enable crops and animals to thrive optimally.

The project also looks at social dimensions of water such as flushing a toilet. “Research activities on redesigning toilets, especially the urinal, where more than nine litres of water are used to flush less than one cubic centimetre of urine, are timely in the context of managing water and the food nexus crises,” said Dr Okorie.

Combining the genetic and social approaches would allow us to produce more with a smaller water footprint. This can be made possible by implementing precision agriculture which is about estimating and applying exact quantities of water and nutrients needed for the production of crops or the raising of livestock.

Paradigm shifting policies
Prof Amusan said the team intended to propose functional solutions that take the quality of water into consideration. Equitable production and distribution of water depends on endorsing policies of co-production between citizens, governments and the public sector. BRICS member states mutually consider water and food security as an issue of paramount significance, hence its feature on this prestigious summit’s agenda.

Postdoctoral researcher, Abdon Atangana, of the Institute for Groundwater Studies at the university recently published an article online about the Lassa Haemorrhagic fever in the Natural Computing Applications Forum. In addition to the terminal transmissible sickness recognised as Ebola haemorrhagic fever, there is another strain called Lassa haemorrhagic fever.

The disease is classified under the arenaviridae virus family. The first outbreaks of the disease were observed in Nigeria, Liberia, Sierra Leone, and the Central African Republic. However, it was first described in 1969 in the town of Lassa, in Borno State, Nigeria.

The main host of the Lassa virus is the Natal Mulimammate mouse, an animal indigenous to most of Sub-Saharan Africa. The contamination in humans characteristically takes place through exposure to animal excrement through the respiratory or gastrointestinal tracts.

Mouthfuls of air containing tiny particle of infective material are understood to be the most noteworthy way of exposure. It is also possible to acquire the infection through broken skin or mucous membranes that are directly exposed to the infective material.

“The aim of my research was to propose a novel mathematical equation used to describe the spread of the illness amongst pregnant women in West Africa. To achieve this, I used my newly-proposed derivative with fractional order called beta-derivative. Since none of the commonly used integral transform could be used to derive the solution of the proposed model, I proposed a new integral transform called Atangana-Transform, and used it, together with some iterative technique, to derive the solution of the model.

“My numerical simulations show that the disease is as deadly amongst pregnant women as Ebola,” Abdon said.

Abdon’s research was submitted to one of Springer’s top-tier journals with an impact factor 1.78. The paper was accepted and published February 2015.
