As an example, the governments of Australia and New Zealand have jointly developed the National Water Quality Management Strategy (NWQMS), the components of which may be incorporated into state and territory legislation, in varying degrees across jurisdictions. In Canada, inter-jurisdictional transboundary water governance mechanisms (such as the International Joint Commission, the Mackenzie River Basin Board and the Prairie Provinces Water Board) serve as collaborative forms to address issues of water quality and quantity. In a first category of countries, these functions are carried out by ministerial departments and/or public agencies; in a second category of countries, such duties rely on specific regulatory agencies in the water sector; and a third category of countries, in the middle of the continuum, significant regulatory powers are granted to specific actors at national level. In Mexico, most environmental regulatory powers are in the hands of the Federal Commission for Protection against Health Risks (Comision Federal para la Proteccion contra Riesgos Sanitarios).
