Peace and environmental sustainability—two lofty but vital goals for all countries—are known to be intrinsically related, according to Dahlia Simangan, associate professor at the Graduate School of Humanities and Social Sciences at Hiroshima University. However, researchers still tend to investigate them separately, and, when they are viewed together, it is often with broad strokes, with little examination into the nuances of either peace or environmental sustainability. Parsing out the specifics of these categories could provide insights into what specific elements of peace influence what specific elements of environmental sustainability, and vice versa, which could then better inform policy and decision making.
