This book presents the concerns, concepts and methodologies of Ecological Discourse Analysis (EDA) based on the shared positions and practices of previous undertakings of discourse analysis. EDA is regarded as an emerging paradigm in discourse studies which undertakes ecologically motivated study of discourses that influences ecological relations. The authors propose a multifaceted ecosophy that incorporates Chinese ethical and philosophical traditions and ecological principles. The ecosophy of 'Diversity and Harmony, Interaction and Co-existence' describes the features of ecological dynamics, providing a basis for the evaluation of the ecological meaning represented in discourses. This ecosophy contributes to such efforts with its origin in Chinese philosophies, therefore offering new opportunities for East-West dialogues on ecological values. An ecogrammar built on Systemic Functional Linguistics is provided as the analytical tool and is applied in the analysis of textbooks, news reports and advertisements. The book also examines the provision of EDA for other fields of study, inspiring research possibilities that are beneficial for an ecological future and inspiring interdisciplinary and multi-methodological studies to be integrated with EDA.
