Assessing ecosystem services of abandoned agricultural lands: a case study in the forested zone of European Russia

The massive abandonment of arable land in Russia in the 1990s had a heavy impact on the country’s land-use structure. The cessation of cultivation leads to a decrease of provisioning ecosystem services within the landscape, while creating an opportunity to enhance the supply of diverse regulation services. Consideration of this opportunity is increasingly important for environmental management and landscape planning. In this article, we present an approach for assessing the environmental benefits of ecosystems developing on abandoned arable lands in the forested zone of European Russia. The proposed methodology is established on a land-cover based framework – ecosystem services assessment matrix. For assessment purposes, abandoned arable lands at different stages of vegetation recovery succession (ruderal, grassland and small-leaved forest) are considered as different land-cover types. Four classes of regulating ecosystem services are subject to qualitative analysis: regulation of the chemical composition of the atmosphere, control of erosion rates, regulation of soil quality and pollination. An exemplary application of the proposed methodology for the case study area located in the Moscow Region of Russia is presented in the article. The results of the qualitative assessment revealed an association between the stage of vegetation recovery succession which corresponds with the time since land abandonment and the supply of regulating ecosystem services. The recovery of natural vegetation leads to higher levels of carbon sequestration, more effective erosion mitigation, soil recovery and increased pollinator abundance. Cropland was proven to be a recipient of the services provided by natural ecosystems. Thus, the return of all uncultivated fields to agricultural use will cause a substantial decrease in the ecological value of the study area.
