This contribution deals with agricultural dynamics in late-Imperial Russia. Based upon a comprehensive micro-level data set on annual yields between 1883 and 1913, we provide insight into regional differences of agricultural growth and the development prospects of Russian agriculture before WWI…
Data on salt-affected soils of Russia are analyzed. Three major problems of current research are outlined: (1) adequate diagnosis of soil salinization, (2) mapping and assessment of the areas of salt-affected soils, and (3) monitoring of the state of soil salinization. On the basis of recent…
The analysis of evaluable information on degradation and dangerous natural processes at the agricultural lands on Asian territory of the Russian Federation (according to the data of 1991-2015) was done. The natural processes negatively affecting the soil (available land) are divided into groups…
The aim of the research is to investigate the impact of complex land reclamation including chemical reclamation, manure applying, and ameliorative tillage on physical and chemical properties of chernozem solonetz. The study was carried out in the Rostov region at two backgrounds: 1 –…
Groundwater vulnerability assessment is an important task in water resources and land management. The most sophisticated among the vulnerability assessment techniques is the GIS-based DRASTIC model. However, despite its popularity, it is marred with excessive subjectivity glitches; little…
