The right to food imposes on all States obligations not only towards the persons living on their national territory, but also towards the populations of other States. The right to food is only realised when both national and international obligations are complied with. On the one hand, is the effect of the international environment and, in particular, climate change, malnutrition and food insecurity. On the other hand, the international community can only contribute if legal frameworks and institutions are established at the national level.
