Upon completion of the PhD in Sustainability, students will be able to:
Students complete 64 credit hours of work across four years (12 semesters) of study in small personalized cohorts. Courses focus on theory, research methods, applied practice, professional development, and dissertation preparation. Throughout, you will learn from professors and advisors from across the globe. This PhD draws on SIT’s 60-year history of experiential education and global partnerships to provide students with a unique and powerful learning experience.
Students can request to transfer up to 15 credits of relevant previous graduate coursework during admission, thereby reducing the overall credit requirement from 64 to 49.
With approval, students can pursue an accelerated pathway to complete the degree in 10 semesters. The research and dissertation writing phase of the program may vary, dependent on individual student progress, outside commitments, and type or scope of research.
In this course, students will delve into the foundational bodies of theory that underpin both research and practical applications of sustainability approaches. This course provides the theoretical background for the discussion and analysis of sustainability issues that range from energy and natural resources to biodiversity and global climate change. Core concepts of the course include social-ecological systems thinking, vulnerability, resilience, regenerative development, policy, and communication in the context of sustainability.
Central to the course is the interconnectedness of sustainability issues across different scales and systems. Students will gain insights into how communities, governments, organizations, social movements, private corporations, and individuals can collectively address the looming threats to sustainability. The exploration of sustainability topics spans a wide array of perspectives, fostering adaptability in addressing the complex task of reshaping human society and its relationship with nature and technology. The overarching goal is to guide individuals towards more sustainable patterns in ecological, social, political, and economic relations while preparing them to be effective communicators of hope throughout their graduate degree and beyond.
This course provides the theoretical background for the use and application of complex systems thinking and decision making for sustainability. The course content draws on diverse fields and spheres, including the social sciences, ecological systems, and technology, with a focus on how these spheres overlap, interact, and how we may further bring them together. Core concepts of the course include social-ecological systems thinking, supply-chain and networks analysis, and ethics and social justice in the context of sustainability. Students will examine interrelationships among natural, societal, economic, technological and political systems on multiple scales, and learn to identify problems and conceptualize solutions using systems thinking.
In this course, students will examine past and current environmental conservation theories, paradigms, approaches, and practices that explore and weigh 1) the challenges and successes of resource conservation on multiple scales, 2) the role of carbon in current and future management of ecological systems, 3) the emergence of environmental governance, and 4) ecological restoration and its potential impacts on human flourishing. Holistic in its approach, the course focuses on the relationships, nuances, and sacrifices involved in balancing human use of natural resources and the maintenance and regeneration of ecological health. The course will also draw on theories and concepts from the pluriverse, environmental psychology, and notions of the inseparable duality of the human-nature mosaic.
Societies in developing countries depend on ecosystem goods and services for their livelihoods. Climate change impacts have damaged the integrity of ecosystems and placed stresses on residents’ livelihoods, public institutions, and businesses. This Praxis course addresses climate change impacts and sustainable practices in the tropics and, furthermore, shows that sustainability is a key factor of the development process. The idea of sustainability emerged in response to growing concerns about the apparent failure of conventional, state-led “development” initiatives and about the extent and pace of socio-environmental degradation, including in African settings. In general, a practice is sustainable and resilient when it can cope with and recover from stress and shocks and maintain or enhance its capabilities and assets, while not further undermining the natural resource base and its multi-sectoral linkages.
This 10-day course takes place in the Zanzibar Archipelago, a semi-autonomous region of Tanzania in East Africa. The course addresses three specific cases by experiencing examples and putting theory and skills into practice where Africa meets the Indian Ocean. During the stay in Zanzibar, we also visit key sites and meet with stakeholders about sustainability practices and challenges, for instance as linked to food production and tourism in an era of climate change. Experiences and applications in Zanzibar are compared against global cases. This course grounds doctoral program themes and tools with on-the-ground experiences and applications in the Global South.
At the conclusion of year one of the program, students must pass a preliminary examination. Preliminary exams demonstrate mastery of content covered in core courses and demonstrated progress towards the dissertation research proposal.
Sustainability assessment balances environmental, social, and economic impacts while respecting contextual and long-term risks. This Research Methods course provides a critical and systematic review of qualitative and quantitative, but primarily mixed methods, approaches to sustainability. Previous comprehension of baseline qualitative and quantitative methods is expected of students. The course also introduces and applies diverse analytical tools essential to the assessment of sustainability cases and outcomes. A broad comprehension of disciplines, scales (space and time), data types, metrics, indicators, and the strengths and limitations of specific paradigms and approaches informs the course and its content. Sustainability evaluations can impact policy and decision-making in both natural/physical and social spheres. Enhanced livelihoods and environmental conservation and social development can result from improved scientific and technical applications that assess the synergies and tradeoffs of sustainability outcomes.
In this course, students will be introduced to a range of approaches and methods used in qualitative inquiry. Among the approaches covered are process tracing, discourse analysis, ethnographic research, case studies, comparative historical analysis, archival research, interviewing, ethnography, content analysis, ethnographic research, political profiling, and agent-based modeling. Students will deepen their knowledge about these approaches and enhance their data collection skills by conducting surveys, analytical frameworks, designing case studies, and reflecting on each method’s strengths and limitations. Students will also learn how to code data inductively and deductively, develop codes, look for patterns emerging in data, develop overarching themes, and interpret findings.
Upon completion of all coursework, students must pass a comprehensive examination and begin a prospectus (proposal) for their dissertation research. Comprehensive exams confirm students’ mastery of their chosen field of study and serve as the basis for their doctoral dissertation literature review. After passing the comprehensive examination and prospectus defense, students enter candidacy.
The Research Colloquium gives a platform for doctoral students to present and discuss possible PhD research projects, exchange ideas, receive constructive feedback, and workshop ways to prepare and improve their dissertation research proposals. Across 10 days, students interact in a conference format, presenting their research ideas, the literature and debates attached to those ideas, and the methods they are considering using in their inquiry process. Students are also expected to critically evaluate the work of their peers, providing constructive criticism to help them advance their research agenda, operationalize their research questions(s), and identify and develop plans for overcoming challenges in the data collection and analysis phases of their research. Prior to the in-person colloquium students will work with their advisor as needed to develop their presentations.
The Doctoral and Professional Development Seminars 1-4 seek to build a community of practice of PhD students as they work to complete their doctoral dissertations. Students meet bi-weekly with each other and their degree chair to share their dissertation progress, problem solve, and share drafts of their work for feedback. The seminar will also feature occasional guest speakers who will share their own doctoral dissertation journeys and their professional transitions after receiving their PhD.
The proposal defense is designed to evaluate the feasibility, significance, and originality of each student’s proposed dissertation research project. It serves as a critical checkpoint to ensure that the research project is well-structured, well-developed, and has a high likelihood of success. The defense is conducted in front of the student’s three dissertation committee members: their primary advisor and their first and second reader. It consists of a formal presentation followed by a question-and-answer session. After the questioning, the committee deliberates, then provides feedback to the student regarding the strengths and weaknesses of the proposal. The outcome of the defense will be one of the following: 1) Pass: the student may proceed with their research, 2) Conditional Pass: The student is allowed to proceed, but they must address specific issues or complete requested revisions to the proposal before doing so, or 3) Fail: The proposal does not meet the required standards, and the student will be required to revise and redefend it at a later date. *Requires successful completion of comprehensive exams.
At least 20 credits of the PhD program consists of research and dissertation. After completion of the dissertation, the student must pass an oral examination in defense of the dissertation.
