Our Gaia Education Interview is here!

“Education doesn't change the world, Education changes people, People change the world” - Paulo Freire

"This is a story of hope, love, pure intentions, perseverance and human connection. It shows how a community of specialists, environmentalists, activists, teachers and beautiful human beings came together to co-create a safe, educational space in nature.

We caught up with Mercia Eichmann, Founder/Headteacher, to find out more about the magic of the centre." Gaia Education - UNESCO

Summer Camp 2022 was a blast!

Summer camp is the time of doing something big. Being a camper is something that most of us miss, as adults. Those few days or weeks, promise the memories that last a lifetime. Summer camping is all about learning, making friends and having fun.

In the heart of nature

As a nature project, we aim to embrace diversity, care for our community and facilitate reconciliation in the world.

We believe in a new vision of education that nurtures children's emotions and sensibility, providing them with the necessary tools, so they can flourish with purpose in the world.

We invite you to join our international community and find out how we could better support each other.

"Researchers agree that increased contact with nature is seen as an integral and vital component of education, particularly in early years settings where Nature projects are being introduced.

Since the eighteenth century, pioneers of early education, namely Froebel, Montessori and Steiner, have valued the outdoors and recognized the importance of contact with nature, with particular reference to learning through active, hands-on play (Constable, 2012)".

The fundamentals of Sustainability Design

The Global Action Programme (GAP) on Education for Sustainable Development (ESD) is a concrete response to the urgent need for a new way of living that respects the limits of our planet’s resources while enhancing our collective well-being.

The programme builds on the momentum created by the UN Decade of Education for Sustainable Development (2005-2014), by scaling up action at all levels and areas of education and learning, to accelerate progress towards the Sustainable Development Goals (SDGs).

Montseny Park Nature Reserve

Montseny biosphere reserve

Montseny massif is one of the outstanding protected areas in Catalonia, so in 1978, UNESCO included it in the MAB (Man and Biosphere) World Network of Biosphere Reserves.

The contour of Montseny starts with elevations of fewer than 200 metres on the eastern side that rise to just over 1,700 m.

The Montseny Natural Park is in the Catalan pre-coastal mountain range. It covers an area of 31,063.94 hectares and is 50km from Barcelona and 25km from the Mediterranean Sea.

The summits in this massif are the highest in the pre-coastal mountain range, and its name (Monte signo) comes from the fact that sailors used it as a landmark to return to Catalonia from their trips in the Mediterranean many centuries ago.
