Freshwater scarcity is not only a concern for some parts of the world but can impact economic,
environmental and social sustainability worldwide (Ahmad, Tower, Plummer, & Aripin, 2010).
In addressing the matter through policy and management, significant stakeholders such as
governments, NGOs, environmentalists, corporations and the public recognise the importance
of high-quality information. They also recognise the necessity for this information to be
reported systematically to confirm that it is related, reliable, comparable over time and across
entities and comprehensible (Muller, 2012). But water scarcity has many consequences, and it
is possible that diverse reporting approaches, called water accounting systems, can be suitable
to treat them (Vardon, Lenzen, Peevor, & Creaser, 2007).
