Geographical Indication (GI) is a sign used on products that have a specific geographical origin and possess qualities or a reputation due to that origin. It helps protect the unique characteristics of products like Champagne, Roquefort cheese, and Darjeeling tea, ensuring that only those produced in the designated area can use the name. GIs are important for promoting local economies and preserving traditional production methods. They also help consumers identify authentic products and prevent misleading practices. By recognizing the link between a product and its geographical source, GIs contribute to cultural heritage and sustainable development.
