She is also a Patron of The Princess Lilian Foundation which was established in 1958 by her late mother.

In the seventies, the foundation focused on organising high-level scientific meetings. Since the death of Princess Lilian, the foundation has created a visiting Professorship. In 2008, she spoke at a conference on mental health and well-being at the European community in Brussels. Maria-Esmeralda is the Honorary President of Care Belgium.
