Problems of farm animals’ ecological keeping in cities

Abstract

   Relevance. On the areas of many cities and suburbs farm animals, which include pigs, quails, sheep, and even cows, are kept. Despite environmental complexity of this problem, it can be successfully solved, otherwise it will become a challenge for modern consumer society. The main ecology problem of the urban environment at farm animals keeping in cities is their biowaste and qustions of its disposal and processing.
   Methods. The method of this study is scientific analysis of literary data, GOST standards, SNIPS, technical regulations and own research and observations in the conditions of existing enterprises for the maintenance of animals in the urban environment.
   Results. According to Rosstat, in 2020 in Moscow 1,3 thousand tons of livestock and poultry of all kinds were raised, including 0,5 thousand tons of cattle; 0,013 thousand tons of pigs; 0,8 thousand tons of sheep and goats; 0,015 thousand tons of poultry. In 2021, sheep and goats production here increased by 20,3 %. For comparison, in Sevastopol, “only” 0,7 thousand tons of livestock and poultry of all kinds were raised, including 0,313 thousand tons of cattle; 0,251 thousand tons of pigs; 0,1 thousand tons of sheep and goats; 0,1 thousand tons of poultry of all kinds. Houses and enterprises built according to “green” environmental standards and new technologies reduce the thermal (carbon) footprint generated by keeping animals in the cities with coatings and building materials’ help. At present there are other technologies with high environmental friendliness, such as ergonomic air ventilation and heating’s systems. The biowaste’s recycling, composting, incineration, burying practice, as well as investments made in the cities urban environment ecology industry bear fruits, and this sector is now developing by 3,5 times faster than other agricultural sectors.
