Abstract

This study assesses the factors that influence land‐cover diversity, including the specific contributions of environmental and anthropogenic forces in determining landscape diversity (spatial variability in climate, lithological variations and human management). The proposed model was tested in Navarra (northern Spain), a region with a long history of human settlement and distinct management practices, ranging from mountain communities in the Pyrenees to Mediterranean lowland cropland systems. Variance in landscape diversity was divided into environmental‐ and human‐influenced fractions, and generalized additive models within a GIS framework were used to evaluate the effects of environmental and anthropogenic factors. We also assessed the influence on the results of the number of land‐cover classes by employing contrasting thematic resolutions of 220 and 24 classes. The model that includes only environmental factors, using 24 classes, accounted for 65 per cent of the total variance (P < 0.005). The residuals obtained from this model were then regressed against human variables (distance to settlements, accessibility, total municipality population and productive specialization). Residuals and productive specialization, which varies between areas devoted to grazing and forest exploitation in the Pyrenees mountains to lowland Mediterranean croplands, showed a strong correlation (r 2 = 0.40; P < 0.005), but weak correlations were found when 220 land‐cover classes were used. Results based on the sign of residuals suggest that human activities have resulted in an increase in land‐cover diversity in mountainous areas and have acted to homogenize land cover within the Mediterranean agricultural landscape. In summary, the model that uses the map of 24 classes as dependent variables and includes human and environmental factors explains 80.75 per cent of total land‐cover diversity variance using only three variables: climatic spatial variability, lithological diversity and productive specialization.

<abstract lang="en">This study assesses the factors that influence land‐cover diversity, including the specific contributions of environmental and anthropogenic forces in determining landscape diversity (spatial variability in climate, lithological variations and human management). The proposed model was tested in Navarra (northern Spain), a region with a long history of human settlement and distinct management practices, ranging from mountain communities in the Pyrenees to Mediterranean lowland cropland systems. Variance in landscape diversity was divided into environmental‐ and human‐influenced fractions, and generalized additive models within a GIS framework were used to evaluate the effects of environmental and anthropogenic factors. We also assessed the influence on the results of the number of land‐cover classes by employing contrasting thematic resolutions of 220 and 24 classes. The model that includes only environmental factors, using 24 classes, accounted for 65 per cent of the total variance (P < 0.005). The residuals obtained from this model were then regressed against human variables (distance to settlements, accessibility, total municipality population and productive specialization). Residuals and productive specialization, which varies between areas devoted to grazing and forest exploitation in the Pyrenees mountains to lowland Mediterranean croplands, showed a strong correlation (r 2 = 0.40; P < 0.005), but weak correlations were found when 220 land‐cover classes were used. Results based on the sign of residuals suggest that human activities have resulted in an increase in land‐cover diversity in mountainous areas and have acted to homogenize land cover within the Mediterranean agricultural landscape. In summary, the model that uses the map of 24 classes as dependent variables and includes human and environmental factors explains 80.75 per cent of total land‐cover diversity variance using only three variables: climatic spatial variability, lithological diversity and productive specialization.</abstract>
