This paper explores the role of practical theology, with a focus on religious education, in addressing the intertwined crises of climate change and displacement through a systematic review of journal articles. As climate change increasingly disrupts communities, leading to displacement and the severing of connections to land and home, practical theology offers a perspective of hope in responding to these challenges. The systematic review encompasses 49 articles, categorised into theoretical, observational, and quantitative studies. Two central themes emerge from this analysis: the recognition of an ecological crisis and the construction of hope. The ecological crisis underscores the urgency of change, particularly as communities are forced to grapple with the trauma of displacement. However, practical theology, through the lens of religious education, provides a framework for understanding and addressing these crises, offering a sense of hope that is essential for both individuals and communities as they seek to rebuild their sense of home. Practical theology can play a crucial role in the reconstruction of community and belonging in the face of environmental disruptions. This study highlights the importance of integrating religious perspectives into broader discussions on climate change and displacement, advocating for practical theology with religious education as a vital tool in nurturing resilience, fostering hope, and contributing to the rebuilding of homes and communities amidst ongoing ecological and social upheaval. By doing so, it suggests that practical theology can become a powerful force for positive change in a world increasingly affected by environmental and social challenges.
