The Research Center in Systems Ecology and Sustainability (RCSES) is the entity of the University of Bucharest dealing with multi and trans-disciplinary research in systems ecology and sustainability.

RCSES teams up with the Department of Systems Ecology and Sustainability in providing top level support for the development and implementation of Sustainability Science. It integrates both basic research related to defining and modeling the structure, dynamics and stability conditions of interrelated terrestrial and aquatic ecosystems and applied research for deeper understanding of interactions within and between socio-ecological systems.

RCSES also integrates observation systems and curiosity driven research, from the smallest scale of genetic diversity to large-scale and even to whole-Earth System. It works across disciplines and facilitate academic, public, private and voluntary sector partnerships. RCSES has extensive experience in long-term monitoring, analysis and modeling, providing early warnings of change and management solutions for our land-waterscapes.
