Conventional welfare analysis would suggest that policymakers should use targeted non-trade policies to offset negative impacts, on the grounds that they do not forfeit the efficiency gains from trade reform and can be targeted to specific beneficiaries. However, there are concerns that some countries, in particular poorer countries, may not have the institutional or fiscal capacity to make use of these instruments, and that some recourse to the levers of trade policy might be necessary. This definition implies that people will only be food secure when sufficient food is available, they have access to it, and it is well utilised. A fourth requirement is the stability of those three dimensions over time, which means the ability to manage risks effectively.
