The present research addresses, in its first part, the increasing threat faced by particularly vulnerable groups in accessing adequate food, in the context of climate change. It highlights the emergence of guaranteeing developments in international and national legal instruments that seek to safeguard this fundamental right. Subsequently, the specific situation in Chile is examined, exploring international standards on climate change and their interaction with the right to food. To this extent, based on a descriptive and explanatory research, using the dogmatic methodology —classical of the legal sciences— and the systematic, analytical and factual sub-methods, the implementation of these standards in the Chilean context is critically observed, analyzing the justiciability mechanisms that seek to ensure the protection and effective realization of the right to food in a scenario of climate change. Finally, it is concluded that is imperative to adopt legal measures of protection of human right to adequate food, by incorporating the international law minimum standards on this matter. This legal enhancing would contribute to moderate the weak image of the Chilean climate law with almost no reference to the human right to adequate food.
