About International Day for Biosphere Reserves
The International Day for Biosphere Reserves is observed on 3 November. UNESCO’s General Conference formally proclaimed the annual day in 2021 through 41 C/Resolution 23.
Biosphere reserves are places in UNESCO’s Man and the Biosphere Programme that combine biodiversity conservation with sustainable development, research, learning and the participation of people who live and work in the landscape.
Why International Day for Biosphere Reserves matters
The observance highlights biosphere reserves as living places rather than protected areas from which people are automatically excluded. Their model links conservation, sustainable livelihoods, science, education and local governance.
A useful guide should distinguish a UNESCO biosphere reserve from a World Heritage Site or a national park: these designations can overlap geographically, but they have different purposes, legal effects and institutional processes.
History of International Day for Biosphere Reserves
Before UNESCO’s formal proclamation, the General Conference record noted that an international day for biosphere reserves was already celebrated in many countries.
At its 41st session, UNESCO’s General Conference examined document 41 C/37 and adopted 41 C/Resolution 23 on 23 November 2021, proclaiming 3 November of every year as the International Day for Biosphere Reserves and inviting the Director-General to promote it.
UNESCO marked the first edition on 3 November 2022 through the Man and the Biosphere Programme, with first-edition events reported in multiple countries. The formal identifiers are kept separate: 41 C/37 is the General Conference document, while 41 C/Resolution 23 is the adopted resolution.
