Each year, we celebrate the International Day for Biological Diversity, or Biodiversity Day, on May 22. The United Nations sponsors this event as a way to increase understanding and awareness of biodiversity issues across the world [1, 2, 3, 15].
The Convention on Biological Diversity and Biodiversity Day
In the late 1980’s, the United Nations convened a series of working groups and negotiating committees to develop an international treaty to guide sustainable use of and address threats to the Earth’s biological resources. Through this process came the Convention on Biological Diversity, which the United Nations adopted on May 22, 1992, in Nairobi, Kenya . The main objectives of this document are 1) the conservation of biological diversity, 2) the sustainable use of the components of biological diversity, and 3) the fair and equitable sharing of the benefits arising out of the utilization of genetic resources . The Convention opened for signature on June 5, 1992, at the Rio Earth Summit and entered into force with 168 signatures December 29, 1993 . There are 196 Parties to the Convention, which meet regularly as the Conference of the Parties to review and make decisions about the fulfillment of the Convention. [5, 6]. Since 2001, the United Nations has celebrated Biodiversity Day on May 22 to commemorate the anniversary of the date that the Convention on Biological Diversity was adopted .
We’re part of the solution, in 2021 and beyond
In 2021, Biodiversity Day is organized with the slogan: “We’re part of the solution” [2, 8, 15]. This connects to the 2020 slogan, “Our solutions are in nature” and recognizes the role we have in crafting sustainable and just solutions to environmental, ecological, and social challenges [2, 15].
This year’s Biodiversity Day generates momentum and support in advance of the meeting of the Conference of the Parties in October 2021 [2, 6, 14]. During this meeting, Parties will make decisions about a post-2020 global biodiversity framework towards the fulfillment of the 2050 Vision for Biodiversity, where the world is “living in harmony with nature” [2, 7, 14, 15].
Given the COVID-19 pandemic, the International Day for Biological Diversity has been moved online. In this context, the Secretariat of the Convention on Biological Diversity asks you to join governments, organizations, and individuals in raising awareness via messages about the importance of biodiversity and how you can be the solution [8, 9]. Be sure to tag @UNBiodiversity and use the hashtags #BiodiversityDay and #ForNature on social media. Also check out different online events, such as the Global Biodiversity Festival.
There are also other ways for you to contribute to international biodiversity goals, even after May 22. Educate yourself and learn how to raise awareness about the value of biodiversity in nature for fostering sustainable human development on a healthy and functioning planet [3, 10, 11, 12, 15]. Make a concrete commitment in line with the reversal of biodiversity loss on the Convention’s Action Agenda tracker, then share your pledge to inspire others and increase ambition !
