The village is the first form of human collective life in a natural arena that has special economic, social-cultural, and physical characteristics. With changes in the activities and characteristics of rural settlements through the expansion of physical space, increase in population and changes in functions, some of them undergo profound transformation. Over time, they experience special physical conditions and gradually become inclined towards urban functions, and the activities also change from agriculture to industry and services. The present study was conducted with the aim of measuring agricultural land use changes and its physical-spatial consequences in Khammam district. The applied method is descriptive-analytical. Data and information have been collected by observation, documentary and field methods. GIS software is used for data analysis. Then, the changes in agricultural land use from 1996 to 2016 have been extracted, compared and analyzed in three classes of agriculture, man-made and barren space. The findings indicate that a significant area of productive land in the studied villages has been changed in favor of other uses. Field observations and questionnaire outputs also indicate that a large area of agricultural land, especially in the target villages of tourism, has been converted into second homes, tourist towns and residential complexes. Also, Most of the effects of tourism are on garden and agricultural lands.

Up-to-date information on land use and land cover, especially in urban areas, and awareness of its changes and developments over a period of time is very important for planners and managers. The present study aims to monitor spatial changes in land use and land cover in the urban area of Babol and Amirkola in the period 1986 to 2020 and forecasting it for 2030. The present research is applied based on the purpose and descriptive-analytical based on the nature and method. Data are taken from Landsat 5 and 8 satellite images. The Fuzzy ARTMAP model was used to detect and classify images, the cross-tab and LCM models were used to analyze land use and land cover changes, and the CA-Markov model was used to predict land use and land cover in 2030 in the IDRISI TerrSet software environment. ArcGIS software was also used to draw the final maps. The results showed that the conversion of garden-use and irrigated agriculture into the built environment has a growing trend, so that these lands have increased from 11.3% in 1986 to 19.7% in 2020 and according to the forecast by 2030, built-up land will reach 22.2% of the total area. Also, the ratio of built-up to non-built land has increased from 12.8 percent in 1986 to 24.5 percent in 2020, and is projected to reach 28.6 percent in 2030, which shows the high rate of garden and agricultural lands destruction.
