Green Water describes moisture that cycles through plants. The forests where this cycle occurs are vital for maintaining air quality and for combatting flooding, desertification and climate change. Yet despite representing two-thirds of the world’s fresh water resources, green water is ignored or mismanaged due to sustained focus on Blue Water – rain which falls into lakes and rivers. This practice-led research seeks to highlight this vital water cycle using three methodologies: soundscape ecology, visual mapping and fine art printmaking. I will acoustically record stages of the green water cycle – transpiration, evaporation and rain. After gathering this evidence, I will translate the sonic data into unique visual mapping artworks, building on my previous sound visualization methodology.These maps, developed through the iterative printmaking process, will form the basis of immersive, audio-visual exhibition experiences.My work will be informed by multiple theoretical disciplines: deep ecology theory (Naess); Gaia hypothesis (Lovelock); systemic thinking (Capra); and climate crises politics (Klein). It will also take inspiration from visual artists e.g. Henrick Håkansson, and soundscape ecologists e.g. Hildegard Westerkamp, whose work contributes to contemporary perspectives of the forest, and artists whose work bridges the audio-visual divide through notation and data sonification. In the volatile time of the anthropocene this work is important and timely. This project draws from cross-disciplinary discussion and encourages discourse about humankind’s relationship to the environment. My unique soundscape visualisations will give the often-overlooked forest flora a voice and a visual language, highlighting the importance of this essential ecosystem. The level of academic excellence and technical expertise within the Royal College of Art, in audio and visual fields, as well as scientific guidance from TECHNE partner institution the University of Brighton’s School of Environment and Technology, make this the ideal environment in which this project can flourish.
