Investigating the rate and the process of land-use change and its economic effects during the last years are among the main bases of land management in the future. East Meshgin region in Ardabil province is one of the agricultural production centers, where the construction of the Sabalan dam developed the agricultural activities. In this research, the six land uses, including rangeland, orchard, agriculture, bare land, outcrop, and water bodies during the years of 1998–1999, were classified using Landsat imagery. Also, the single and comprehensive dynamic land-use change indices were employed to compute the rate and process of land-use change. The land-use change matrix is developed in three time periods (1998–2003, 2003–2008, and 2013–2019). The economic evaluation of land use has been conducted during this period. The results showed that the highest rate of land-use change was converting the rangeland to bare lands. While in the period of 2008–2013, the highest rate of land-use change was rangeland conversion to agriculture lands that has caused increased net income by 4027,258 $. The collected data relates to the total period also confirms the change of rangeland use to bare lands. Also, the results of the single dynamic land-use change model show that in each period, the most change was related to water body land use. Among other land-uses, the highest rate of change was related to agricultural land use between 2013–2019 in the period of Sabalan dam operation. This study is performed to facilitate policymakers, planners, and other development stakeholders in this sector to adopt the best option for land-use management and sustainable land development. |
