Food security is defined by Wikipedia as “the availability of food and one’s access to it”. Usually we speak about individuals when we talk on food security, but we can easily extend this concept to societies at large. A society enjoys food security if there is enough food available for its members, and they have access to this food.
A society has two ways to ensure that the supply of food is sufficient: by producing its own food, or by importing such food. Once enough food is available, ensuring that each member of society has access to sufficient food is the big concern. The implementation of an adequate basic income guarantee will provide everyone with the means to buy food. Hence the sole concern would be availability of sufficient amount of food.
Related to food security is the concept of food power, which is the use of food as a mean to exert power. If country A depends on the import of food from country B, the latter country can exert power on country A by denying supply if A does not meet certain conditions establish by B. These condition might be unfavourable to A, and hence this country looses sovereignty.
Space settlements has to choose between producing or importing food. If the latter option is chosen, the space settlements became vulnerable to the exertion of food power by Earth. In this way terrestrial governments might force space settlements to implement policies, which are in violation of their own preferences. If, however, the former option is chosen, a powerful weapon is denied to terrestrial governments to influence the (domestic) policies of space settlements.
If we want to implement the social reforms we desire in space settlements, such as our proposals for monetary and banking reform, it’s of great importance that these settlements have a certain degree of independence. Therefore space settlements should be able to produce their own food. In another post we will discuss how space settlements can grow food.
