UNESCO’s Mission
Conserving and cultivating the olive tree is a growing imperative as the world combats and adapts to climate change. The protection of cultural and natural heritage, including landscapes, is at the heart of UNESCO’s mission and marking World Olive Tree Day reinforces environmental sustainability efforts. Olive trees prevent desertification and protects against soil erosion. As an agent against global warming olive trees have a positive carbon balance. They take more CO 2 out of the atmosphere than is emitted during the olive oil production process and they also have the potential to increase atmospheric carbon dioxide fixation in the soil.
Olive oil and table olives are a proven source of nutrition, and key ingredients in the Mediterranean diet. However, they offer a wide variety of aromas and flavours and enhance a unique cuisine. This has gained interest from renowned chefs around the world. The ability of their multiple medicinal and nutritional properties to prevent certain diseases is now widely recognised.
