22 May World Biodiversity Day 2026
World Biodiversity Day 2026 invites us to take a clear-eyed look at the health of our ecosystems and to recognize how the variety of species, habitats, and natural processes is fundamental to the planet’s balance.
Biodiversity is not an abstract concept: it is what makes food production, water quality, soil fertility, climate resilience, and the well-being of societies. In recent years, however, the erosion of biodiversity has accelerated at an unprecedented rate. Habitat loss, pollution, intensive land use, climate change, and the spread of invasive species are reducing the ability of ecosystems to regenerate and sustain life. The World Biodiversity Day is therefore a crucial moment not only for reflection, but above all for action.
This year’s theme, “Act Locally, Impact Globally”, is a clear and direct call to recognize the fundamental role that every territory, community, and individual can play in safeguarding our natural heritage.
Biodiversity thrives in agricultural landscapes, vineyards, wildflower meadows, pollinating insects, and even urban gardens. Protecting this richness means safeguarding the future of our environment, our food production systems, and the traditions that shape the identity of our territories.
The loss of biodiversity has a direct impact on our daily lives. Ecosystems rich in species are more resilient, more productive, and better able to adapt to climate change. Among the most important ecosystem services are:
- Pollination, essential for more than 75% of food crops
- Climate regulation, thanks to forests, oceans, and soils that absorb CO₂
- Soil fertility, ensured by microorganisms and soil fauna
- Water quality, maintained by wetlands and riparian ecosystems
- Ecological resilience, which enables ecosystems to withstand stress and disturbances
The 2026 theme is part of the Kunming-Montreal Global Biodiversity Framework, which aims to reverse biodiversity loss by 2030. Among the most relevant objectives:
- Protect at least 30% of terrestrial and marine areas
- Restore at least 30% of degraded ecosystems
- Reduce the use of pesticides and harmful substances by 50%
- Integrate biodiversity into agricultural, urban, and industrial policies
But global targets can only be achieved if they are translated into concrete actions at the local level: from the sustainable management of agroecosystems to the restoration of habitats, from the protection of water resources to the creation of green infrastructure in cities; and above all through a coordinated effort between governments, businesses, the scientific community, and citizens.
