Edges of sustainability through numbers, themes and discourse: A critical analysis of theses and dissertations in Turkish higher education institutions

The purpose of this paper is to identify critical gaps in the conceptualization and interpretation of sustainability by investigating the postgraduate research (theses and dissertations) conducted with a reference to sustainability in Turkish higher education institutions and synthesizing the underlying themes and trends pertaining to sustainability issues in the local discourse.

The study adopts a mixed-method design. The sample (n=343) consists of the theses and dissertations conducted over a ten-year period in Turkish universities. Data analysis procedures include a quantitative investigation through numbers to address the level of value attached to postgraduate research on sustainable development; a content analysis on the focus and scope of each study to determine prevalent sustainability themes and dimensions frequently addressed in the studies; and a collocation analysis conducted on the texts of the studies to depict linguistic and cultural connotations of sustainable development in the local discourse and key terms that frequently collocate with sustainable development in the Turkish context.

Neither a sufficient number of direct references to sustainability nor a substantial increase in the number of studies throughout the decade is depicted. Only one-third of Turkish universities steer postgraduate research on sustainability, which is not evenly distributed to various institutions across the country. Three-quarters of the studies are conducted within economy-related and engineering-related programs. The social dimension of sustainability is under-researched. The topics tend to ply between environmental and economic edges. Turkey, as a word, is collocated frequently with the concepts of external debt, current deficit, energy, policy, and EU. Linguistically, the concept of sustainable development is predominantly associated with economic growth in the majority of the studies. Sustainability is contextualized mostly with making cities inclusive, safe, resilient and sustainable and promoting inclusive and sustainable economic growth, employment, and decent work.

The value of the paper lies in the paucity of studies tracking the research initiatives taken on sustainability, assessing research trends in postgraduate programs of higher education institutions, and looking into a global concept from a local perspective in a developing country, Turkey.
