Sustainability Science (REASOn – Resources, Food and Society)

Sustainability Science (REASOn – Resources, Food and Society)

The Universidade de Lisboa Doctoral Degree in Sustainability Science (REASOn) had its first edition in the academic year 2018/2019.

This PhD focuses on the dimension of food production and consumption as a central vector of the challenges facing sustainability, recognizing that understanding food systems and acting on the global food system are fundamental instruments for sustainable development and require research on the interactions between ecology and socioeconomics.

To be catalysts for change, 21st century professionals must be endowed with solid scientific knowledge and, above all, be able to incorporate it to understand the interactions between global, natural, social and human systems, and how these interactions affect sustainability challenges.

The PhD was conceived within the scope of Colégio Food, Farming and Forestry (F3), mobilizing a faculty that includes 42 professors from 17 of the Faculties and Institutes of the University of Lisbon, which guarantees the necessary innovation and interdisciplinary approach.

Designed for successful professionals and for the best students who seek to turn knowledge into innovation and tangible results, with an academic background in any area of knowledge. This Study Cycle allows the development of doctoral thesis in a university environment, in a business/industry environment or – in an innovative typology in relation to the traditional 3rd cycle offer – in a professional work context. The latter model offers the possibility of conducting a thesis on a scientific research question that is relevant to the exercise of the students' everyday professional activity and can be developed with or in the employer organization, exploring the double translation between practice and science.

The programme opens with curricular units designed to deepen scientific skills, translating in a Doctoral Degree, with a duration of 2 semesters and a workload of 60 ECTS.
The curricular units are sequentially arranged according to their purpose of subject framing, thematic amplification and orientation for thesis.
The following three years are dedicated to the development of the doctoral thesis and include two seminar courses that ensure the continuity of interaction and knowledge exchange between students in each cohort, and between them and all professors associated. Seminars will further promote the participation of professionals from sectors related to the Doctoral Degree thematic fields and national and international renowned personalities, providing students a privileged contact with real organizational and business environments and with additional perspectives on the challenges addressed.
