Human activities on Earth are central to the food security challenge. An optimal, rational approachto this challenge is to harmonize the processes and structures of human, economic and social developmentwith natural foundation of the land. This study was carried out based on data related to anthropogenictransformation with a set of data on the type of activity, intensity of intervention and land-use trends. The typeof human impact or land-use included ۴ function and ۱۱ activities. The intensity of the intervention was definedbased on four indicators. The trend of natural transformation was based on the magnitude of the land deviationfrom its original equilibrium state of changes in vegetation and physical characteristics. This study covers anintegrated approach to the complex issue of anthropogenic transformation. Which can be used as a basis forevaluating human impact on a larger scale.
