Assessment of damage from soil and land degradation at three hierarchical levels of the administrative and economic structure of the Russian Federation: subjects, municipalities and agricultural farms
Abstract
Th e damage caused by soil and land degradation was assessed at three hierarchical levels (the region as a whole, the municipality, the agricultural sector) of the spatial organization of six test regions of the Russian Federation (Volgograd, Belgorod, Kaliningrad, Vladimir, Samara and Penza regions). Th e indicators of soil and land degradation for all test objectswere a decrease in the content of exchangeable potassium, a decrease in the content of mobile phosphorus, a decrease
in the content of humus, a change in the acidity index of soils. In addition, for the test objects of the Volgograd region, the indicator of land salinization was used, the Belgorod region — soil erosion, the Kaliningrad region — the indicator of the metabolic coeffi cient (qCO2) of soils. It was found that the minimum and maximum values of the specific total damage fr om degradation can be detected for regions with a similar composition of soil cover (Saratov and Belgorod regions, respectively, wh ere chernozem soils predominate). When the values of specifi c total damage from soil and land degradation are close to each other at various hierarchical levels of spatial organization of regions (Vladimir, Saratov, Belgorod and partly Penza regions), in terms of intensity and scale of manifestation of the studied degradation processes, the agricultural farm is «typical» for the entire municipal district, and the municipal district is «typical» for the entire region.
