This book critically examines the impact of migration, education, development, and the spread of English on global bio-linguistic and cultural diversity. Derived from findings from a comparative eco-linguistic study of intergenerational language, culture, and education change in the Tibetan Diaspora, the book extends its analysis to consider the plight of other peoples who find themselves straddling the Indigenous-Minority-Diaspora divide. Mac Pherson explores the overlapping and distinctive sustainability challenges facing indigenous and minority communities when they are connected by and within diasporas, and seeks to adequately explain the discontinuities and disjunctures between their educational struggles and achievement levels.
