Modeling climatic, terrain and soil factors using AHP in GIS for grapevines suitability assessment

The study carried out in Matera, Italy, used multi-criteria decision-making techniquesand geographic information systems to identify optimal area management for sus-tainable grape production. Terrain parameters such as temperature, pH, humidity, soiltexture, slope, altitude, nutrients and precipitation were considered. ArcGIS mapswere created, and the northwest part of the field was identified as a favorable area.Fuzzy maps were generated, and measurements were taken in each area to deter-mine optimal land management. The results revealed that 51% of the area was veryhighly suitable for agricultural activities, and 49% was considered high suitable.Receiver operating characteristic (ROC) analysis of the AHP results demonstrated ahigh level of accuracy, as indicated by the area under the curve (AUC). The producedmaps indicated a similar trend of increasing zone management priorities for physico-chemicals as depth fluctuate. Additionally, results showed that remote sensing indi-ces were the most important variables to predict physico-chemicals zone manage-ment. The study also highlighted that the majority of the area supported plantgrowth due to favorable temperature and humidity conditions, with only a small por-tion in the northwest showing less favorable results. By identifying managementzones, the study aimed to protect crops, better use of irrigation water and improveyields. This study highlights the potential of integrating satellite remote sensing, GIStechnology and AHP as a valuable tool for agricultural land use planners and policymakers in identifying optimal locations for managing grape production.
