across someone else's land. Other In addition, there are various forms of collective ownership, which typically take either the form of membership in a cooperative, or shares in a corporation, which owns the land (typically by fee simple, but possibly under other arrangements). There are also various hybrids; in many communist states, government ownership of most agricultural land has combined in various ways with tenure for farming collectives. Land tenure in archaeology In archaeology, traditions of land tenure can be studied according to territoriality and through the ways in which people create and utilize landscape boundaries, both natural and constructed. Less tangible aspects of tenure are harder to qualify, and study of these relies heavily on either the anthropological record (in the case of pre-literate societies) or textual evidence (in the case of literate societies). In archaeology, land tenure traditions can be studied across the longue durée, for example land tenure based on kinship and collective property management. This makes it possible to study the long-term consequences of change and development in land tenure systems and agricultural productivity. Moreover, an archaeological approach to land tenure arrangements studies the temporal aspects of land governance, including their sometimes temporary, impermanent and negotiable aspects as well as uses of past forms of tenure. For example, people can lay claim to, or profess to own resources, through reference to ancestral memory within society. In these cases, the nature of and relationships with aspects of the past, both tangible (e.g. monuments) and intangible (e.g. concepts of history through story telling) are used to legitimize the present.
