This research conducted by Barış Özkan, Orhan Dengiz, and İnci Demirağ Turan explores agricultural potential in Central Anatolia's semi-arid ecosystem, covering approximately 195,012.7 km². Using advanced GIS techniques and fuzzy MCDA, they identify areas suitable for sustainable farming, highlighting the importance of soil characteristics in arid regions.... show more

Abstract

The main purpose of this study is to identify suitable potential areas for agricultural activities in the semi-arid terrestrial ecosystem in the Central Anatolia Region. MCDA was performed in a fuzzy environment integrated with GIS techniques and different geostatistical interpolation models. Nine criteria (four terrain properties and five soil features) were used to identify potential agricultural lands in Central Anatolia (≈195,012.7 km²). Criteria weights were assigned using FAHP. Inputs included a 10 m DEM, digital geology and soil maps, CORINE land use/land cover, long-term meteorological data, and 4517 soil samples. Approximately 30.7% of the total area (59,921.8 km²) is very suitable or suitable (S1 and S2) for agriculture, 27% is marginally suitable, and 42.7% is not suitable. Additionally, 34.8% of the area is slightly suitable.
