"Forest restoration: a path to recovery and well-being" is the theme of the International Day of Forests 2021. The United Nations General Assembly proclaimed 21 March the International Day of Forests in 2012 to celebrate and raise awareness of the importance of all types of forests.


Forests cover one third of the Earth’s land mass, performing vital functions around the world. Around 1.6 billion people – including more than 2,000 indigenous cultures – depend on forests for their livelihoods, medicines, fuel, food and shelter.

Forests are the most biologically-diverse ecosystems on land, home to more than 80% of the terrestrial species of animals, plants and insects. Yet, despite all of these priceless ecological, economic, social and health benefits, global deforestation continues at an alarming rate.

The United Nations General Assembly proclaimed 21 March the International Day of Forests in 2012. The Day celebrates and raises awareness of the importance of all types of forests. On each International Day of Forests, countries are encouraged to undertake local, national and international efforts to organize activities involving forests and trees, such as tree planting campaigns.

2021 Theme

The theme for 2021 is “Forest restoration: a path to recovery and well-being”. Restoring forests helps build a healthier world for ourselves and for future generations. By replanting and managing forests sustainably, we can help preserve our planet’s biodiversity and combat climate change while fostering economic activity that creates jobs and improves lives as we enter the UN Decade on Ecosystem Restoration (2021-2030).

Launched by the government of Germany and IUCN,  the Bonn Challenge is a global goal to bring 150 million hectares of degraded and deforested landscapes into restoration by 2020 and 350 million hectares by 2030. It unites nations and regions in bringing landscapes into restoration, to halt and reverse the effects of land degradation. At present, pledges cover 210.12 million hectares, with more than 61 countries involved.

Importance of Forests

According to UN-REDD, forests are home to about 80% of the world’s terrestrial biodiversity and an estimated 1.6 billion people use forests for all or part of their livelihoods such as food, shelter, energy and income. Millions, including people in cities, depend on forest resources for clean air and fresh water.

During the day, trees absorb carbon dioxide for photosynthesis and give out oxygen, the air that we breathe. The carbon in forests exceeds the amount of carbon currently in the atmosphere. Forests and forest soils store more than one trillion tonnes of carbon.

Hence, forests play a crucial role in fighting catastrophic climate change by absorbing and storing massive amounts of CO2. In addition, trees could reduce temperatures in cities up to 8°C, lowering use of air conditioning and related emissions by up to 40%. But as we cut them down, oftentimes to make space for agriculture, they lose their ability to regulate the global climate.

During heavy rains, trees reduce the risk of flooding. Experts say that woodland acts as a barrier to floodwater, while trees also prevent soil erosion, reducing sediment going into rivers and increasing water absorption into the ground. Forests can also retain excess rainwater, prevent extreme run-offs and reduce the damage of flooding. They can also help mitigate the effects of droughts by releasing water in the dry season, forests can also help provide clean water and mitigate the effects of droughts.

Furthermore, more than a quarter of modern medicines, worth an estimated US$ 108 billion a year, originate from tropical forest plants.

Global Distribution of Forests

The Food and Agriculture Organization of the United Nations (FAO) indicates in its 2020 Report “The State of the World’s Forests” that the total forest area is 4.06 billion hectares, or approximately 5,000m2 (or 50 x 100m) per person, but forests are not equally distributed around the globe.

More than half of the world’s forests are found in only five countries (the Russian Federation, Brazil, Canada, the United States of America and China) and two-thirds (66 percent) of forests are found in ten countries.

Build Back Better and Greener

Forests, through their ecosystem services, are a key nature-based solution for rebuilding the global economy post-pandemic in a way that preserves nature, while fostering growth. The United Nations Environment Programme (UNEP) provides some key insights on how forests can help make us more resilient in the longer term.

Local Geneva

Canton of Geneva

Geneva is active in protecting biodiversity and forests, especially due to their proximity to the urban areas. While the human population is close to nature, it also induces significant pressures on the environments. As proposed in Geneva’s Strategy Plan on Biodiversity, it is essential to promote biodiversity at every scale, from land use planning to concrete achievements in neighborhoods or gardens. In addition, te forest reserve of the Grand Bois de Satigny was established by Geneva’s Conseil d’Etat on 23 May 2018.  With nearly 100 hectares, it is one of the largest integral forest reserves in the Swiss Plateau, thus meeting the recommendations and priorities of the Swiss Confederation. All logging and active management of natural environments is prohibited in this reserve. The reserve remains fully open to the public and will offer future generations the opportunity to discover a large space devoted entirely to nature and its natural evolution.

City of Geneva

Renowned for its parks, the City of Geneva has also approximately 70 hectares of forests, managed in an optimal and ecological way.

Faune Genève

Faune Genève is a non-profit association aiming at protecting and raising awareness on the fauna of Geneva. Its website is an official platform for naturalists and wildlife observers in the region.

La Libellule

La Libellule is a non-profit association raising public environmental awareness through field activities, mainly in the Geneva region.
