Abstract
This paper examines the problem of agricultural land abandonment through
knowledge of driving factors. First, we reach out a review of the concept of
abandonment in order to define the negative and positive aspects of this process
in the landscape. Then we focus on a real case study in the Marina Baja region
(SE Spain). Finally, we propose, from a theoretical perspective, the use of a
methodology to define the most important variables for studying the
abandonment processes in this region.
First of all, we performed various analyses using Geographical Information
Systems (GIS) to create a geodatabase which stores the main factors generally
associated with abandonment. The variables considered can be grouped into
three groups: environmental (such as climate, soils or relief), socio-economic
(such as demographic, accessibility or technology) and those related to cultural
practices in the crop (such as irrigation or rain-fed stone walls).
Considering over a hundred variables we need to answer two questions: (1)
which of the variables are really driving factors in the abandonment process of
an agricultural plot? and (2) how important is each of them alone or in
combination with others? The authors advocate the use of GIS for the feature
creation or management and Data Mining techniques to perform the feature
selection. Specifically, we propose the use of a concrete metric, aci (Attribute
Correlation Index), to answer the questions raised above.
