Water is absent in the ‘Voluntary Guidelines on the Responsible Governance of Tenure of Land, Fisheries and Forests in the Context of Food Security’ (FAO, 2012). This paper explored whether and how the people-centred approaches and the human rights values that underpin this document can be better applied in the water sector and how more recognition of the land-water interface can support this.

Presents a theoritical outline of the techniques in the use of tritiated water (HTO) which can be used to estimate total body water, body composition, water turnover, milk intake and feed intake. Highlights its potential errors and gives a comprehensive methodology for the use of tritiated water under field conditions.
