Spatial patterns of farm land use in fragmented semi-arid landscapes: The case of Lebna catchment (Cap Bon, Tunisia)
Résumé
Mediterranean agricultural landscapes provide ecosystem services driven by land use patterns such as crop spatial distribution (Millennium Ecosystem Assessment, 2005). Assessing the determinants of crop location is therefore a prerequisite for exploring spatially explicit land use scenarios and evaluating the subsequent ecosystem services (Benoît et al., 2012). Although remote sensing techniques are now able to provide time series of land use patterns, they do not permit to identify the driving factors of crop location that are related to farm characteristics. Intra-farm land fragmentation is a typical characteristic of rural landscapes (Demetriou, 2014), and we hypothesized in the current study that it may strongly influence crop spatial patterns. Therefore, the current paper aimed to study the impact of farmland fragmentation in crop location within a semi-arid rural zone of Tunisia, with a focus on spatiotemporal dependencies.
