'Wicked Problems' are those problems facing the planet and its inhabitants, present and future, which are hard (if not impossible) to resolve and for which bold, creative, and messy solutions are typically required. The adjective 'wicked' describes the mischievous and even evil quality of these problems, where proposed solutions often turn out to be worse than the symptoms. This wide-ranging and innovative book encourages readers to think about archaeology in an entirely new way, as fresh, relevant, and future-oriented. It examines some of the novel ways that archaeology (alongside cultural heritage practice) can contribute to resolving some of the world's most wicked problems, or global challenges as they are sometimes known. With chapters covering climate change, environmental pollution, health and wellbeing, social injustice, and conflict, the book uses many and diverse examples to explain how, through studying the past and present through an archaeological lens, in ways that are creative, ambitious, and both inter- and transdisciplinary, significant 'small wins' can be achieved. Through these small wins, archaeologists can help to mitigate some of those most pressing of wicked problems, contributing therefore to a safer, healthier, and more stable world.
