We examine the implementation of these authors’ technique for assessing the agricultural impact on natural systems for purposes of strategic governance of agrarian nature management by using the Smolenskii district of Altai krai as an example. The study area is located in different natural zones at the interface between the West Siberian Plain and the Altai mountain system, which determines the specialization of agriculture and the specific character of agricultural impacts on natural systems. The suggested technique includes the following stages: assessment of the degree of agricultural impact and its deviations from an optimal level; correlation of the indicators of the degree of agricultural load with the landscape structure of the study territory using landscape (geosystem) approach, and analysis of the positive or negative consequences of the agricultural impact on natural systems. An assessment of agricultural impacts on the natural systems in the study area showed that, according to most of the indicators used, the degree of disturbance to natural systems refer to a class of ecological risk, while the agricultural load varies from permissible to critical. The distinctive characteristics of the occurrence of the agricultural load within the study area were identified on the basis of landscape approach. The algorithm of actions included calculating the structure of lands within the boundaries of landscapes (at the level of localities) by use of the agricultural and landscape maps of the area and GIS tools; determining the compliance of the structure of land use to ecological standards for each natural zone; analyzing the current agricultural utilization of the territory within the boundaries of natural systems; updating the structure of land use, and suggesting approaches to its optimization. We identified the landscape complexes requiring a reduction or cessation of economic activity, and suggested measures for optimization of agricultural loads.
