Book excerpt: Design Roots provides a comprehensive review of culturally significant designs, products and practices which are rooted to particular communities through making tradition and a sense of place. Many rich traditional practices associated with community, tacit knowledge and culture are being rapidly lost due to globalisation and urbanisation. Yet they have much to offer for the future in terms of sustainability, identity, wellbeing and new opportunities in design. This book considers the creative roots, the place-based ecologies, and deep understandings of cultural significance, not only in terms of history and tradition but also in terms of locale, social interactions, innovation, and change for the sustainment of culturally significant material productions. Importantly, these are not locked in time by sentimentality and nostalgia but are evolving, innovative, and adaptive to new technologies and changing circumstances. Contributing authors explore the historical roots of culturally significant designs, products and practices, emerging directions, amateur endeavours, enterprise models, business opportunities and the changing role and contribution of design in the creation of material cultures of significance, meaning and value. An international perspective is provided through case studies and research from North and South America, Africa, Europe, Asia and Australasia, with examples including Aran jumper production in Northern Ireland, weaving in Thailand, Iranian housing design, Brazilian street design and digital crafting in the United Kingdom.
