Assessing the economic marginality of agricultural lands in Italy to support land use planning
2018
Abstract Agricultural
marginalityis a multifaceted issue, being related to place-specific socioeconomic contexts and highly-variable technological conditions. The coexistence of different classification systems of these variables makes hard any attempt to have a general definition of agricultural
marginality. Moreover, the spatially explicit identification of
marginal landsis still challenging mostly due to the lack of reliable data sources at both country and regional scale. Accordingly, this paper evaluates the degree of economic
marginalityof
agricultural land, using Italy as a representative case study for southern Europe. A
spatial analysisof farmland profitability and constraints for agricultural activities (topography and biodiversity conservation) is proposed to identify three classes of
agricultural land, namely ‘unsuitable’, ‘supramarginal’ and ‘
marginal’
lands. Results show that almost 39% of
agricultural landin Italy can be classified as ‘
marginal'; its spatial distribution and characteristics are also analyzed and discussed in relation to different background conditions. The proposed approach provides a valuable methodology supporting
land-use planningand decision-making under restricted geo-spatial data availability.
