Land tenure theory (Le Roy et al., 1996)

- Allows to measure level of ownership and co-management of the

customary territory.

- Correlations of the three types of data that characterize traditional African law:

Type of land control

Co-management mode

Hypothesis:

Translation of the majority of land tenure objects from a loose land control with undefined management unit to strict land tenure with precise owners.

Land tenure rule could be used as an indicator to appreciate forest transition at the SES level and predict the presence of tipping points

Level of agricultural expansion + rise in population density  drastic reduction of land available to individual occupancy, leading to hardening of land tenure rules.

Private land ownership and its commercialization

We demonstrate that individual land tenure increases along with the deforestation process.

Land tenure could be used as an indicator of SES shifting more sensitive than evolution of forest cover to appreciate forest transition at SES level Need for further studies to determinate the tipping points thresholds
