The Dean of the Wits Faculty of Science, Professor Nithaya Chetty, has been appointed as the chair of the International Union for Pure and Applied Physics (IUAP) Working Group on Physics for Climate Action and Sustainable Development, while Visiting Professor Igle Gledhill from the School of Mechanical, Industrial and Aeronautical Engineering, is serving as its secretary.
These appointments, effective for an initial three-year term, were confirmed during the IUPAP General Assembly held this week in Geneva. Chetty also serves as the vice-president of the Union responsible for membership and development and oversees the global development of physics. Both Chetty and Gledhill are previous presidents of the South African Institute of Physics.
“Issues around climate change are set to grow in the coming years,” says Chetty. “These challenges are intimately connected with the need for energy security and sustainability of the environment and, if not addressed, will impact negatively on poverty, inequality, mass migration, and the human condition. These are global problems that require a global effort and a more focused quest for the green economy.
“This is a multidisciplinary endeavour involving the basics sciences like physics, chemistry, mathematics, computing, engineering, human and social sciences, law and health sciences,” he adds. “This terrain is fraught with political influences and it is essential to carefully differentiate between academic discourse on the one hand and political discourse on the other – and between climate action and climate activism.”
Chetty says that the working group’s primary objectives include promoting the distinct role of physics in addressing climate change and the energy transition. It aims to achieve this by:
* Advocating for an evidence-based approach to climate studies and the energy transition, collaborating closely with experts from various fields;
* Establishing robust global connections to engage the public in discussions on these vital topics; and
* Encouraging the integration of green economy and sustainability principles into university curricula and research training.
The working group, comprising of experts from around the world, will offer recommendations to the Executive Council of the IUPAP on actionable measures, tasks, and statements.
Over the next three years, it plans to organise at least one significant international conference. The group is also committed to active participation in initiatives related to the United Nations’ International Decade of Sciences for Sustainable Development, declared in August 2023, an initiative also led at the UN by the IUPAP.
“Amongst other initiatives, our discussions revolve around the formulation of a comprehensive programme aimed at enhancing the field of physics in the Pacific Island nations,” says Chetty. “It is crucial to underline that one of IUPAP’s core missions is the global advancement of physics.
“However, we hold concerns that island nations and economically disadvantaged countries, especially African countries, will disproportionately bear the brunt of the myriad challenges confronting humanity in this coming decade. Given that physics serves as a pioneering discipline, it becomes imperative that we foster its growth in these regions.
“This, in turn, forms the bedrock for the advancement of science, resulting in a deeper comprehension of societal issues and a more profound commitment to collaboratively devising solutions.”
