This study evaluates the implementation of sustainable landscape strategies in selected Pentecostal churches located in Lagos-Ogun megacity, with an emphasis on their capacity to minimize environmental impacts. Although the role of religious institutions in promoting sustainability is becoming more recognized, there is a significant lack of research on how these techniques are implemented in quickly expanding metropolitan areas. This study aims to assess the extent to which churches have incorporated sustainable practices into their surroundings. The study used a qualitative methodology that combines literature review and field observations to examine the implementation of diverse sustainable landscaping strategies in these churches. The findings reveal significant disparity in the commitment to and effectiveness of these practices among the churches studied. The results suggest that while some institutions are taking meaningful steps toward sustainability, others exhibit substantial gaps that could be addressed with more targeted efforts. The discussion highlights the broader implications of these findings, emphasizing the need for increased awareness, investment in sustainable infrastructure, and more comprehensive adoption of environmentally friendly practices. The study concludes that while progress has been made, there is considerable room for improvement, and these churches have the potential to play a more active role in environmental stewardship within their communities. This research contributes to the existing body of knowledge by providing insights into the current state of sustainability efforts in religious institutions and offering recommendations for enhancing these practices.
