Abstract |
The ecological and economic study of land degradation at the regional level (the Moscow Region) was carried out using analysis of literature sources, methods of correlation regression analysis and “impact / inaction assessment”, where economic indicators (grain and vegetable yields, total sown area, net vapors, costs and revenues, etc.) were used as independent variables, and the indicator of the area of degraded agricultural lands as a dependent variable. With the help of spatial and dynamic models, it was shown that the factors affecting the degradation of the region's lands are extensive factors (expansion of crops and clean fumes) and intensive (insufficient intensification in the form of small inadequate amounts of mineral and organic fertilizers) factors, or, more precisely, insufficient intensification as an insufficient amounts of mineral and organic fertilizers. In addition, negative dynamics of the balance of useful elements in the soil of the Moscow region during the period 1995—2014 was established, which is a negative factor in the development of the region's agriculture. The application of the “action / inaction” method has shown that restoration (improvement) of land productivity and support of ecosystem services are economically justified. |
