5 reasons why the International Day of Forests matters

This year’s International Day of Forests highlights the vital role of forests in food security, nutrition, and sustainable livelihoods. This year’s theme, “Forests and Foods,” connects forests to global efforts to combat hunger, protect biodiversity, and address climate change. Here are 5 reasons why this year’s theme is so important.

1. Forests feed the world 

Forests provide a variety of edible resources, from fruits, nuts, and seeds to wild game and mushrooms. More than five billion people depend on forests and non-timber products for food, medicine, and income.

2. Forests are key to achieving zero hunger 

By sustaining pollinators, improving soil fertility, and regulating water cycles, forests enhance agricultural productivity. Agroforestry—a farming method that integrates trees and crops—can boost food security while preserving ecosystems.

3. Forest conservation is climate action 

Forests act as carbon sinks, absorbing billions of metric tonnes of CO₂ annually. Sustainable forest management helps mitigate climate change, protecting food systems from climate-related disasters like droughts and floods.

4. Forests maintain biodiversity and life on land 

Forests host 80% of terrestrial species, supporting ecosystems that sustain healthy, resilient food systems. Protecting forests is crucial for maintaining biodiversity, preventing land degradation, and securing food sources.

5. Forests support livelihoods and local economies 

Millions, especially Indigenous Peoples and rural communities, rely on forests for employment and income. Strengthening sustainable forest-based value chains—like non-timber forest products—improves economic resilience.

The International Day of Forests, observed annually on 21 March is led by the UN Forum on Forests Secretariat, UN DESA, and FAO to raise awareness and promote sustainable management, conservation and sustainable development of all forests and trees for present and future generations. This year’s International Day of Forests reminds us that forests and food are deeply interconnected.
