UN Agreement on the Ocean, a historic step forward

On March 4, a historic agreement was reached by the United Nations to preserve marine biodiversity. Christophe Prazuck, director of the Océan Institute, discusses this major step forward and the participation of the Sorbonne University Alliance in this international scientific effort.

An agreement has been reached at the United Nations on a treaty for the conservation and sustainable use of marine biodiversity in the oceans that are not under national jurisdiction. That is, the ocean located more than 360 kilometers from the coast, outside the Exclusive Economic Zones, which represents two thirds of the ocean and half of the surface of our planet.

This breakthrough has been described as historic after 15 years of negotiations. It is a step forward on a scale not seen since 1982 and the adoption of the United Nations Convention on the Law of the Sea. It is a step forward that responds to a fact: the ocean is changing under the effect of climate change, pollution and over-exploitation. This transformation directly impacts marine biodiversity, threatening its balance and the services it provides.

If each State can act in the waters under its jurisdiction, we were almost powerless to act in the waters that are not under any jurisdiction, until now. Fish, plankton and marine organisms do not read maps and do not know borders; what happens in the open ocean always ends up affecting the coastal areas and vice versa.

This historic agreement is not a conclusion, it is a step forward. This step is necessary, because it must allow the implementation of operational tools to ensure the conservation and sustainable use of marine biodiversity.
The ocean sciences and humanities community of the Sorbonne University Alliance will be involved and concerned in the engineering, implementation and evaluation of these tools, marine protected areas, impact studies and more. 

Thanks to the number and quality of its laboratories and researchers, it will participate significantly in the international scientific effort that will accompany the future treaty. It will be a question of better observing the ocean, better understanding it and making it understood, and recommending better decisions to political authorities, decisions whose relevance and effectiveness must be better ensured.

A new era is beginning for ocean sciences and humanities.

Health Sciences

The Faculty of Health Sciences teaches the 3 cycles of medical studies: from PASS (integrated into the faculty) to the 3rd cycle including DES, DESC, DU and DIU. The lessons are given mainly on two sites: Pitié-Salpêtrière and Saint-Antoine. The faculty also provides paramedical education: speech therapy, psychomotricity and orthoptics. The Saint-Antoine site includes a midwifery school.

Welcome to Sorbonne University's Faculty of Science & Engineering

A unique combination of courses and expertise

Our international study programmes are organised according to the major disciplinary areas of the faculty. They represent the graduate study programmes that are not strictly conducted in French or that could be suitable (in part) for non French-speaking students. They also reflect part of the diversity of the disciplines involved and the bi- and inter-disciplinary aspects of many of the courses we offer.


Research & Innovation

We rely on disciplinary skills and on interdisciplinary approaches to renew concepts, methods and research subjects and to focus on some of the crucial issues faced by our societies: transformations affecting the very construction of knowledge (data, AI), the treatment of complex objects (the environment, marine and ocean sciences, cultural heritage) or our contributions to addressing societal challenges (climate change, healthcare).

Our campuses offer different and unique experiences to our students, visitors and staff. Resources and support services are also available to ensure an equal chance at success to all.

Campus Life

In addition to the cultural activities and events organised throughout the year by our clubs and societies, the Parismus society organises numerous events, evenings and cultural visits that will help you discover France and its parisian life.
