Water is the most important natural resource for the continuation of healthy human life. Thus, it is imperative to pay attention to how this resource is managed in the face of various water crises and the imminent threat of many others. As a public good, regulated by national and international norms, the management of water and its distribution with quality and equality falls under the responsibility of a state that guarantees rights. However, reality tells a different story. Various efforts towards increasingly privatizing and commodifying this resource can be observed, consequently limiting, and excluding its access to the most vulnerable populations. Large industries, especially in the food sector, play a significant role in this dynamic. This research aims to analyse this dynamic from the perspective of International Law, looking at specific cases in the United States and Brazil, major global agribusiness powers. A legal perspective will be used to particularly observe the Brazilian condition and discuss possibilities for agency in such a complex scenario.
