We hear from experts, biologists, geologists and managers of the Portuguese Biosphere Reserves who talk to us about this Programme, which was born in 1971 with the aim of promoting knowledge, practice and human values to implement good relations between populations and the environment across the planet. The uniqueness of the Portuguese Biosphere Reserves is also represented by those who, as part of the community of these territories, stand out for their resilience. They are responsible for the past, present and future of the reserves.
