Mapping the energy potential of cereal crops waste in the Ryazan region

Over the past half century, there has been a steady increase in the share of electricity generated by renewable energy sources. For the regions of the Russian Federation, in the economy of which agriculture plays a significant role, it is important to use crop waste for the purpose of their further processing and use as a source for electricity generation. In a number of articles, the analysis of resources at the regional level is carried out only on the basis of statistical data summarized by administrative divisions. In this paper, a methodology based on the use of remote sensing data of the earth is considered, which allows localizing the source of energy resources (fields of grain crops). The technique was implemented for the Ryazan region. The selection of the contours of agricultural fields is based on the multitemporal satellite images of Landsat-8 and Sentinel-2, which depict agricultural fields at different stages of the growing season. Since most types of grain crops are characterized only by the course of vegetation development, which is accompanied by a change in spectral characteristics, it is possible to separate grain from other types of agricultural crops. On the basis of well-known formulas, the energy potential of individual fields was calculated. Agricultural enterprises of animal husbandry in the region were chosen as places where concentration and processing of grain crops wastes is possible. Based on the road graph of the Ryazan region, the Location-Allocation problem was solved. As a result, on the basis of the shortest distance along the road network, the belonging of each field to a certain processing point was determined. This problem was solved for 3 cases: 100, 50 and 10 processing enterprises. The results showed how much the difference is between the energy potential calculated on the basis of administrative statistics and the energy potential calculated using remote sensing data and network analysis.
