Geographical indications (GIs) are collective trademarks used on products that have a specific geographical origin and qualities due to that origin. GIs support local producers and product quality while protecting against unfair competition. They provide economic benefits like higher prices and new markets for producers, stability and jobs for communities, and quality assurance for consumers. GIs can promote sustainable local development by encouraging environmentally-friendly practices and preserving local agro-economies. The document provides examples of GIs and recommends further reading on their economic and policy implications.
