Exploring farmers' adaptation strategies to water shortage under climate change in the Tunisian semi-arid region.

This study explores the adaptation strategies to water shortage at the farm level in the Tunisian semi-arid region and investigates factors determining the farmers' behavior. In this area, climate change exacerbates the scarcity of water resources, groundwater suffers from saline intrusion, and the reinforcement of surface water depends on the water transfer decision. Based on 81 farmers survey data collected in Diar El Hajjaj irrigated area, the typology of farmers was constructed using the multivariate technique combining the clustering method and principal component analysis.
