Purpose: to determine the most advantageous composition of the agro-reclamation measures complex from the ecological and economic positions and its placement taking into account the natural resource, as well as historical and social potential of the lands occupied in agricultural production.
Materials and methods. Version programming of the agricultural area development process using modern capabilities of computer modeling allows predicting the effect depending on a hypothetical change in external conditions and identifying the most advantageous strategies for the reclamations development and placement from a variety of options. Methodological approaches to the strategy formation are based on the enumeration of all possible options represented by combinations of interacting reclamations combinations and related agro-reclamation factors, with subsequent assessment of their effectiveness. The choice of options is based on the methodological approach to identifying indices of the state of environmental components.
Results. Calculations of the integrated assessment of the efficiency of options for a period of 25 years were performed using the initial most costly technical and economic indicators of reclamation measures. The production and economic characteristics of 254 options for the composition of the complex reclamation measures for sod-podzolic soil of average cultivation in Ryazan region (grass-grain crop rotation) are given. The majority of options (90 %) show low productivity and negative profitability, 8 % of options with high productivity are characterized as “ecologically stressed”, and only 2 % of options meet all the requirements.
Conclusions. Already at the stage of implementing an investment project in the agro-industrial complex, measures to compensate for and prevent negative phenomena are provided. Highly effective measures can be implemented only if expensive additional measures to ensure the preservation of the natural environment and compliance with regulatory environmental requirements are included.
