Voluntary return in safety and with dignity as a durable solution to displacement has long been a core tenet of the international refugee regime. In the 23 articles on Return in this issue of FMR, authors explore various obstacles to achieving sustainable return, some of which are common to diverse situations of displacement while others are specific to certain contexts. Many of the authors discuss the need to guard against premature or forced return, and the risks that such return may entail. They also debate the assumptions and perceptions that influence policy and practice. The examples of good practice and the reflections on research findings presented in this issue are drawn from around the world. The issue also contains a mini-feature on Towards understanding and addressing the root causes of displacement which has been prepared to inform discussions at the first Global Refugee Forum in December 2019. With a collection of articles written by authors from the UN, NGOs and academia, the mini-feature aims to enhance collective understanding of some of the root causes of displacement.The full print issue can be found online at: www.fmreview.org/return
