The notion of ecology has become central to contemporary design discourse. This reflects contemporary concerns for our planet and a new understanding of the primary entanglement of the human species with the rest of the world.The use of the term 鈥榚cology鈥?with design tends to refer to how to integrate ecologies into design and cities and be understood in a biologically-scientific and technical sense. In practice, this scientific-technical knowledge tends to be only loosely employed. The notion of ecology is also often used metaphorically in relation to the social use of space and cities. This book argues that what it calls the 鈥榖iological鈥?and 鈥榮ocial鈥?senses of ecology are both important and require distinctly different types of knowledge and practice. It proposes that science needs to be taken much more seriously in 鈥榖iological ecologies鈥? and that 鈥榮ocial ecologies鈥?can now be understood non-metaphorically as assemblages. Furthermore, this book argues that design practice itself can be understood much more rigorously, productively and relevantly if understood ecologically. The plural term 鈥榚cologies design鈥?refers to these three types of ecological design. This book is unique in bringing these three perspectives on ecological design together in one place. It is significant in proposing that a strong sense of ecologies design practice will only follow from the interconnection of these three types of practice. Ecologies Design brings together leading international experts and relevant case studies in the form of edited research essays, case studies and project work. It provides an overarching critique of current ecologically-oriented approaches and offers evidence and exploration of emerging and effective methods, techniques and concepts. It will be of great interest to academics, professionals and students in the built environment disciplines. 銆€ 銆€
