Scholars also called attention to the importance of possible UN recognition of human rights to water and sanitation at the end of the twentieth century. Two early efforts to define the human right to water came from law professor Stephen McCaffrey of the University of the Pacific in 1992 and Dr. Peter Gleick in 1999. McCaffrey stated that "Such a right could be envisaged as part and parcel of the right to food or sustenance, the right to health, or most fundamentally, the right to life. Gleick added: "that access to a basic water requirement is a fundamental human right implicitly and explicitly supported by international law, declarations, and State practice."
