This thesis comprises of a body of creative work and an exegesis that articulates the intentions and findings from each project. The creative portfolio is specifically focused on the development and dissemination of original electroacoustic music compositions that draw on environmental field recordings from various parts of the world. The central research question of this thesis investigates the possibilities of electroacoustic music composition in contributing towards environmental awareness and engagement. This research adopts a practice-led methodology, resulting in 24 original creative works presented as the major component of this study. The research question was addressed from a personal perspective, through a detailed autoethnographic commentary on the development of each project. The research has been conducted in cultural immersion, ranging from the centre of the Amazon rainforest to exploring significant rivers in India, Korea, China, and Australia. The findings and observations from each project led to preliminary results that highlighted the value of creating electroacoustic music in community engagement and using multi-platform dissemination of the resulting experiences. These results gradually led to the development of the Sonic Ecologies framework, a production model that the author introduces in this dissertation that underpins the creative portfolio and articulates the practice-led outcomes
