Abstract
There are many reasons and background factors for conflict including differences in political and social beliefs and values. Wars have also been a threat to the environment and sustainability. Inequality and disparity are more apparent in the world due to COVID-19. Now, we also need to consider environmental changes caused by human activities as climate extremes might cause new conflicts. More studies are needed for a comprehensive understanding of holistic views on challenges at the interfaces of peace and sustainability that inherently involve inter- and trans-disciplinary collaboration among cohorts of communities of practice. Collaborative scientific research on these interfaces is being conducted under the Future Earth Programme, and many others. In this commentary, I posit that science offers an effective pathway and a common platform for engagement and interactions aimed at the nexus of sustainability and peace under global changes.
