This year’s 8th World Water Forum in Brazil—the largest gathering on this subject, held every three years—will for the first time bring judges and prosecutors together with policymakers from around the world to discuss the precarious state of freshwater resources and the importance of rule of law in achieving water resource objectives. Recognizing this, the Environmental Law Institute, in collaboration with the Global Judicial Institute for the Environment and the International Union for Conservation of Nature World Commission on Environmental Law, is dedicating this section of this issue of the Environmental Law Reporter to marking the symbolic and reflective importance of the role of the judiciary in achieving water justice and ecological sustainability. The Comments we present here—all written by practicing senior judges—speak to the legal and scientific complexity involved in adjudication of water controversies in different jurisdictions, the criticality of rule of law in protecting and maintaining water resources, the central role of the courts in advancing environmental rule of law, and the approaches judges are taking in their effort to fulfill this role.
