Book excerpt: Innovations and Challenges in Applied Linguistics from the Global South provides an original appraisal of the latest innovations and challenges in applied linguistics from the perspective of the Global South. Global South perspectives are encapsulated in struggles for basic, economic, political and social transformation in an inequitable world, and are not confined to the geographical South. Taking a critical perspective on Southern theories, demonstrating why it is important to view the world from Southern perspectives and why such positions must be open to critical investigation, this book: charts the impacts of these theories on approaches to multilingualism, language learning, language in education, literacy and diversity, language rights and language policy; provides broad historical and geographical understandings of the movement towards a Southern perspective and draws on Indigenous and Southern ways of thinking that challenge mainstream viewpoints; seeks to develop alternative understandings of applied linguistics, expand the intellectual repertoires of the discipline, and challenge the complicities between applied linguistics, colonialism, and capitalism. Written by two renowned scholars in the field, Innovations and Challenges in Applied Linguistics from the Global South is key reading for advanced students and researchers of applied linguistics, multilingualism, language and education, language policy and planning, and language and identity.
