Abstract

As a result of the reform to the Water Code through Law 21, 435/2022, the original budgets that supported the market logic to which the rules for allocation and reallocation of water were subject have been altered. Currently, sectoral legislation adopts a new approach in which the prioritization of water use for human consumption and sanitation coexists with protecting the ecosystem services provided by water. Both institutions significantly altered the water market, which was based on efficient resource allocation. We will see how, with the introduction of the ecosystem preservation function, there has been a greening of the legislation, which has had an impact on the purpose of water publification. In this way, the contours of ecosystem preservation, its relationship with water security, its foundations, and the tools through which the greening of water legislation occurs will be analyzed to conclude how the reasons that justify the publification of waters, currently, are discharged in an efficient and equitable use of the resource. © (2024), (Universidad de Chile.
