Abstract Food security is usually identified as a desirable outcome depending on a variety of factors such as food availability, access and distribution. Food self-sufficiency is one of the key factors when it comes to evaluating food availability. Furthermore, food selfsufficiency is not only a national concern but also relevant on a sub-national scale. A consumption-oriented approach is proposed to measure the degree of self-sufficiency on a regional scale. In our proposal, exports are subtracted from domestic supply to assess the share of domestic production in domestic consumption. By doing so, the effects of regional specialization in export crops on our estimates are avoided. Due to its increasing relevance in consumption patterns, the food industry is included as a separate group of food items. Owing to their small size, high density of human activities, specialization in tourism, and remoteness from the European continent, the Canary Islands are an interesting laboratory for illustrating the advantages and shortcomings of measuring food self-sufficiency on a local scale.

attention in public debates. These debates cover an ideologically diversified spectrum of interpretations concerning the present and future food situation in high and low-income countries. The way food is produced depends on the structural characteristics of the economic system and its mode of production. In a capitalist economy, food production is linked to markets and property rights; food itself is a priced good and food sufficiency includes the economic dimension of affordability in terms of income. A healthy diet not only includes absolute but also relative availability of different types of food. Furthermore, rising incomes transform
