  abstract = {{T}he main challenges of {T}unisian arid areas is better understand desertification and better adapt decisions to uncertainties that arise in complex interactions between the socio-economic and biophysical dynamics at different spatial and temporal scales. {T}his understanding is increasingly necessary to better target actions and improve coping strategies. {T}he objective of this work is to assess the vulnerability of natural resources and the risk of desertification at the local scale, in a case study ({O}um {Z}essar watershed) located in the south-east of {T}unisia. {T}he assessment is carried out through an analysis of different human and biophysical causes and driving forces, such as natural resources uses and climate change. {I}t is based on geographical (landscape), integrated (socio-economy, biophysics) and multi-actors (research-decision) approaches, associated with reproducible methods and models to assess the risk of desertification, and to better target future combating actions. {T}he work led to the development of desertification risk indexes (based on spatial integration of biophysical and socio-economic functioning through modeling), facing several scenarios of climate change and human pressure. {I}t shows that the same level of risk in one place or another may have differentiated causes, which could help public policy in their fighting against desertification.},
