In many cases tour operators use local food and crafts as one of the tourist attractions of their packages Food and crafts can generate considerable profits for the local population, when volume production and delivery at set quality standards can be met by local producers. Key issues for local sourcing of food supplies in the tourism sector are quality, reliability and quantity of supply. Promotion of local sourcing therefore requires training and technical support and investment - for example in storage and distribution facilities - to meet quality and reliability standards, as well as the development of production and distribution networks to gather supplies from different local producers into the quantities required by hotels.
