In recent decades major of arable land are extended and there are significant competition for arable land use change. Development of Technology on the hand and Wheat self-sufficiency strategy, lack of arable land, prohibition of national land change and fertile soil of forest land, on the other hand, convert the agroforestry to one of the prevalent methods in less development regions of Zagros forest in Iran. This research investigated the challenges and opportunity of agricultural major strategies and their effects on sensitive ecosystem in Iran. Then by utilising land SAT 5 and 8 images and sentinel images land use changes was analysis by using Object-oriented programming during 1990-2020. The results show that agricultural lands (irrigated and dry farming) have grown by 40% in the study area. Meanwhile, forest lands show 10% decrease and rangelands a 6% increase. The study of land use changes showed two major types of changes for the occupation of forest lands: the first category is the direct conversion of forest lands to pastures and second category is the gradual conversion of forests to agricultural lands (due to cultivation under the mezzanine). The second group is done by mixed cultivation of wheat in forest lands and then the expansion of lands by reducing the number of trees and finally complete capture over time. The results of this study show that the second category is far more dangerous than the first category due to continuous habitat threats and the occupation of a large part of the land. Also, results of research show land use change continuity increase exploitation and erosion, leads to soil erosion, land abandonment, and finally alteration of this land into deserts.
