Territorial Identity and Development (May 2022)
LANDSCAPE DYNAMICS IN THE SOMEȘ CORRIDOR. CASE STUDY: GURUSLĂU DEPRESSION (ROMANIA)
Abstract
Changes in land use patterns induced by different agricultural practices are reflected territorially through transformations at the level of elementary landscape units, with an impact on territorial identity and cohesion. The aim of this study is to highlight the dynamics of the territorial structures in the post-communist period (1990-2018), diachronically reflected in the transformations of the landscape of the Guruslău Depression, using the landscape metrics. The main direction of the scientific research was based on the analysis of land use changes and the identification of the spatial elements of structural-landscape distinction with impact on land degradation process. The evaluation of the landscape dynamics in the current context uses several effective metrics and tools, which increasingly require the identification of interdisciplinary methods of analysis, with a decisive impact on territorial development. Besides, the present approach is also motivated by the increasing environmental impact of climate change. The methodology used in the present paper is based both on the geoprocessing of vector data using GIS tools and correlated spatial analysis, and on the identification of landscape types using a new process of reclassifying land use categories, according to a set of landscape definition variables. The results of the research highlighted both the particularities of landscape transformations that occurred in the reference interval, as well as the favourable conditions for addressing biocultural diversity, by identifying traditional agricultural practices and the resilience of geographical landscapes given the adaptation to changing development strategies. Meanwhile, by detecting the landscape structures affected by change, in correlation with the impact induced on the biodiversity of the territory, the present study has a wide applicability in the most appropriate implementation of local development policies, as well as in identifying the forms of sustainable valorisation of the landscape in the study area.
