This paper answers the question: has the Colombian Congress been effective at addressing relevant water conflicts and making them visible? While courts and social movements have been key for the advancement of social rights in Latin America, the role of legislators remains unclear. We conduct content analysis of all water-related bills, proposed bills, and constitutional amendments filed in Colombia from 1991 to 2020; we also analyzed Congress hearings of political control related to water; and the statutes of political parties who hold majority of seats in Congress. We also and conducted interviews with key actors on water governance in Colombia. We find that only three bills have passed in the 30-year time frame and that relevant water conflicts have not been addressed by Colombian legislators. We find that water conflicts are not reaching the political agenda of Congress, yet through political control hearings, it has given some late visibility to critical territorial conflicts in which water is a key element. We analyze our data in light of literature on legislative politics and legal mobilization in Latin America. This study adds to global research on the role of legislators in advancing the human right to water, particularly in Latin America.

Laws that recognise rivers and their ecosystems as legal persons or subjects with their own rights, duties and obligations have been associated with theories of environmental constitutionalism. However, the extent to, and manner in which, constitutional law (with its elevated status) has been instrumental in the conferral of these 'riverine rights' is still not well-understood. In this article, we consider the constitutional relevance of the recognition of rivers as legal persons or subjects in Aotearoa New Zealand, Colombia and India. We argue that in these three countries riverine rights are constitutional experiments: as small-scale, ad hoc and ultimately incomplete attempts to transcend seemingly ineffective regulatory frameworks for rivers. However, they are also incremental, and influential, steps in a broader project of more fundamental social and environmental reform.

In this paper we compare recent efforts towards the constitutionalization of the right to water in Brazil, Colombia, and Peru to understand the opportunities and limitations related to the attempts to enhance access to piped water to the highest normative level. Peru passed a constitutional amendment in 2017 while Brazil and Colombia have seen much right-to-water activism but have not succeeded in passing such reforms. We explore the role of the existing domestic legal frameworks on drinkable water provision and water management towards the approval of constitutional amendments. We find that all three countries have specialized laws, water governing institutions, and constitutional jurisprudence connecting access to water with rights, but the legal opportunity structures to enforce socio-economic rights vary; they are stronger in Colombia and Brazil, and weaker in Peru. We argue that legal opportunity structures build legal environments that influence constitutional reform success. Legal opportunity structures act as incentives both for social movements to push for reforms and for actors with legislative power to accept or reject them. Our findings also show that in some contexts political cost is a key element of constitutional reforms that enshrine the right to water; therefore, this is an element that should be considered when analyzing these processes.
