This year we celebrate the 16th anniversary of Greenfest with hybrid events (in person + digital). Exclusive, different schedules and experiences.

Central theme for the 2023 Editions: The Regenerative Circular Economy and “Nature-Based Solutions”!


Regenerative Circular Economy
and “Nature-Based Solutions”

The term “Nature-Based Solutions” refers to sustainable management and the use of its mechanisms to respond to the enormous socio-environmental challenges we face. The challenges include such urgent topics as combating climate change, access to clean water, pollution, food security, human health, loss of biodiversity, ecosystem degradation, climate migration and disaster risk management. The list of challenges could go on… and immediately include all the SDGs 2030, whose objectives have become even more demanding and complex with the covid-19 pandemic.

Nature is an authentic “living laboratory” that is about 4 billion years old and many of the solutions to the aforementioned challenges are, or could be, in deciphering natural mechanisms and their applicability to human well-being. Regeneration is one of its pillars, as is the decoding of the genome of fauna, flora, land and sea. Biomimicry, combining various disciplines of our knowledge and inspiration from nature, can be a powerful ally in overcoming challenges and contributing to a healthy transition to a regenerative circular economy, with inclusive, resilient and sustainable communities.
