This article deals with the inventory and assessment of TOF - inventory being the process of finding out quantitatively and qualitatively how much of a resource there is, and assessment the process of putting the inventory data into a context and assigning values to the resource. The focus is on inventories for large areas such as provinces, countries or regions, as opposed to the more common studies for smaller areas such as farms or groups of farms. After discussing definition and classification of TOF, the article outlines survey options. Particular reference is made to experiences and examples from Latin America.
