Rapid Urban growth, the increase in destructive activities, development of unsuitable land use and irregular exploitation of water, soil and vegetation resources has substantially threatened land resources across the world. Finite arable lands are considered as one of the most important areas the largely affected from this situation. Generally, the application of Spatial Multi-Criteria Decision Making (SMCDM) techniques in association with linear combination methods of integrating criteria maps is the primary way of analyzing the suitability of land for a variety of application especially for agricultural land use which due to dependence on a large set of criteria are time consuming and expensive. Fortunately, based on progressive advances in space born remote sensing techniques, it is now more viable to accurately and quickly evaluate the suitability of land resources for loading land use activities. In this research effort, Segzi Hydrological Unit, Isfahan was used as a case study to simultaneously evaluate the suitability of land for agriculture based on the comparison of the results obtained through an SMCDM technique (as a quantitative method) and application of remote sensing (as a qualitative method). In case of quantitative evaluation, weighted linear combination method was used to integrate a large set of soil and water factors. Moreover, in the qualitative process, we relied on a decision tree method and processing of two Landsat images acquired on April 1 and June 18, to ), indicating high capability of remote sensing in evaluation of land for agricultural activities. According to the fact that this branch of remote sensing application is new, it is recommended to conduct more studies in different geographical areas and by using a variety of remote sensing imagery data and vegetation indices.
