The search for a permanent solution for public stockholding for food security purposes has been going on for some time now, but still no such solution has been found. This paper attempts to provide an analytical framework to a) rethink domestic support within the realm of the World Trade Organizations Agreement on Agriculture (AoA) and b) to test possible permanent solutions for public stockholding of foodstuffs for food security purposes in light of (i) sustainable development, (ii) the right to food, and (iii) the sovereignty of the Member States. It looks at domestic support from a sustainable development perspective in order to facilitate the incorporation of the right to food into the international agricultural trading system while ensuring the sovereignty of the Member States. Looking at the problems from such a perspective reveals not only that the WTO Agreement on Agricultures rules on domestic support are in urgent need of reform, but also that the problem of public stockholding for food security purposes is far more complex than commonly suspected. Therefore, a differentiated approach is needed.
