Prof Melanie Walker, an A1-rated researcher, is one of the foremost academics in human development and education studies.

Prof Melanie Walker, Distinguished Professor in the Centre for Development Support at the University of the Free State (UFS), has been elected as President of the Human Development and Capability Association (HDCA). This is the first time that the HDCA president is from the Global South. 

The HDCA is an international association for academics and practitioners who, according to Prof Walker, “seek to create an intellectual community around the ideas of human development and the capability approach and relate these ideas to development practices and the policy arena”. 

Prof Walker holds the SARChi Chair in Higher Education and Human Development, and is one of three A-rated National Research Foundation (NRF) researchers at the UFS. She follows in the illustrious footsteps of previous HDCA presidents, including esteemed academics such as Prof Martha Nussbaum, who received an honorary doctorate from the UFS in 2012, and Nobel prize winner, Amartya Sen

An established UFS presence 

Since its inception in 2004, Prof Walker has been involved with the HDCA through various positions and roles, thus establishing a strong UFS presence within the organisation. “We already have a strong research presence in the HDCA through the group I have established at the UFS, which is now well-known and highly respected,” Prof Walker says. She is also hopeful that more researchers from the UFS may consider joining the HDCA and developing human development-focused research partnerships with others in the HDCA.

Highlighting Global South issues 

Through her new position as president-elect of the HDCA from September 2021, she wants to expand the reach and responsiveness of the HDCA in Sub-Saharan Africa (SSA). “In Southern Africa we have a growing community, but we need to be stronger elsewhere.  This would provide the platform to take forward public debates about inequalities as obstacles to sustainable human development,” Prof Walker says.  However, these problems and challenges occur everywhere in a world of “growing inequalities and exclusions”. 

In these COVID-19 times, a focus on human development seems more needed than ever - Prof Melanie Walker 

Apart from expanding the presence of the HDCA in SSA together with its executive, Prof Walker hopes to “further strengthen the organisation and its research, practice and policy ‘voice’, and its capacity-building activities. I would also like to put ideas from decoloniality and the North-South knowledge inequalities on the table, as well as our knowledge-producing practices.” 


The global presence of the HDCA 

The international footprint of the HDCA is extensive, with members in more than 70 countries. The organisation hosts an annual international conference, bringing together various thematic groups, regional networks, and holds regular webinars and workshops. It also publishes the peer-reviewed Journal of Human Development and Capabilities.  The HDCA promotes research within a vast array of disciplines, ranging from economics to philosophy, development studies, health, education, law, government, and sociology.  “The HDCA takes forward significant capabilitarian scholarship with shared purposes to advance knowledge, development practices, and policy in and for human development,” Prof Walker says. 

The organisation aims to challenge the narrow understanding of economic growth as the end of development, and of human capital production as the prime purpose of education. “In these COVID-19 times, a focus on human development seems more needed than ever,” Prof Walker says.

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Description: Dr Lehlohonolo Koao  Tags: Dr Lehlohonolo Koao

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
