Water is a fundamental human right, says Dr Thulisile Mphambukeli, (left) Senior Lecturer at the Department of Urban and Regional Planning. On the right is Dr Victor Okorie.

Research shows that “access to water and food remains critical to the survival and stability of any nation”. This is according to a team of academics that has been hard at work exploring ways in which to secure water and food in Brazil, Russia, India, China and South Africa (BRICS nations).

These scholars from the University of the Free State (UFS) and North-West University recently published a paper titled: Exploring the Political Economy of Water and Food Security Nexus in BRICS. Dr Thulisile Mphambukeli, Dr Victor Okorie, and Prof Samuel Amusan are members of the Food Security Research Cluster of the South African BRICS Think Tank that has been fervently tackling the water and food in(security) challenge.

Water as a key to social justice 

The team argues that unequal access and distribution of water has in the past led to violent conflict. The paper cites Qwaqwa as one of the many areas affected by water-service protests in the recent past. “Water and food crises are worsening thanks to the intensification of climate change, rapid urbanisation, nutrition transition and population growth. Solutions to these crises partly lie in cooperation and collaboration among nation states, regional economic commissions, and global power brokers.”

What are some of the local solutions? According to the scholars: “For agronomic and husbandry practices, there is a pressing need for research activities on innovative ways of supplying water to crops and animals such that water loss through evaporation and run-off is significantly reduced. 

“Similarly, research activities on redesigning toilets, especially the urinary section – 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 the water and food security nexus crises.”

Improving livelihoods

In an effort to achieve food security, BRICS aims to stimulate domestic capacity for production. Food and nutrition security cannot be achieved without water security, and vice versa. 

It is evident that the water and food insecurity issues are complex. However, concerted efforts are being made by various sectors to solve these challenges and improve the livelihoods of urban and rural citizens within BRICS nations.

Plant eco-physiologist finds effective solutions for crop optimisation

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
