Sustainability is a complex and pressing 21st century systems problem. The United Nations Sustainable Development Goals (SDGs) identify 17 areas where focused attention is needed to address issues of rising inequality and poverty globally, entrenched gender inequality, economic growth, and environmental issues related to climate change. Around the world, governments at all levels, corporations, scientists of various disciplines, and individual citizens are finding ways to contribute to the sustainable development agenda. Vocational psychology can also have a role to play. Sustainability however, is a complex systems problem that will not be addressed through simple solutions or single disciplines because of the interconnectedness and pervasiveness of the issues. Transdisciplinary research has the capacity to tackle complex systems problems such as the SDGs e.g., gender inequality because it involves multiple stakeholders, employs systems thinking, and is solution focused. Systems thinking takes a holistic view of issues and considers the interconnectedness of parts of the system. Transdisciplinary research and systems thinking go hand in hand by involving multiple stakeholders including those whose voices are less heard, who bring diverse knowledges to issues and through dialogue and collaboration, co-design solutions. Transdisciplinary research however, is not without its challenges. This presentation will overview the Sustainable Development Goals and identify areas in which vocational psychology could make a contribution. It will introduce transdisciplinary research and systems thinking and consider their strengths and challenges. Examples will be provided of how vocational psychology could contribute to transdisciplinary research related to the Sustainable Development Goals.
