Gleick also did some of the earliest work defining a
human right to water. In the 20th century, the early focus of
human rights laws were on political and civil rights protected by the 1948
Universal Declaration of Human Rights. By the 1960s, however, scholars and human rights experts were calling attention to economic, social, and cultural rights as well, with the 1966 covenant on
International Covenant on Economic, Social and Cultural Rights (ICESCR). While neither of these declarations addressed water, by the 1990s, there was growing concern about the failure to provide safe water and sanitation for hundreds of millions, and scholars were calling for explicit recognition of a human right to water. 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 Gleick in 1998. 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. and the United Nations cited this work in General Comment 15, drafted in 2002, which provided their clearest definition of the human right to water to that point
United Nations Committee on Economic, Social and Cultural Rights in General Comment 15 drafted in 2002. General Comment 15 was a non-binding interpretation that access to water was a condition for the enjoyment of the
right to an adequate standard of living, inextricably related to the right to the highest attainable standard of health, and therefore a human right. It stated: "The human right to water entitles everyone to sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses." That Resolution recognized the right of every human being to have access to sufficient, safe, and affordable water for personal and domestic uses. In September 2010, the UN Human Rights Council adopted a resolution recognizing that the human right to water and sanitation forms part of the
right to an adequate standard of living. Gleick’s work on basic water requirements and human rights was also used in the
Mazibuko v. City of Johannesburg court case in
South Africa addressing the human right to water in Phiri, one of the oldest areas of the
Soweto township. The Pacific Institute contributed legal testimony for this case based on the work of Dr. Peter Gleick and the work of the Centre for Applied Legal Studies (CALS) of the
University of the Witwatersrand in Johannesburg, South Africa and the
Pacific Institute in Oakland, California was acknowledged with a 2008 Business Ethics Network BENNY Award. ==Current work==
