The use of remote sensing, ground survey and the yield mapping system in the conditions of northern Kazakhstan for food production and food security

Abstract

Food security is among the most important aspects of our physical health; it is necessary to live a full and peaceful life. Food security is a wide term that encompasses more than crop production since it necessitates taking into consideration geographical and temporal variability, along with economic and physical availability. Drought and salt stress are two major variables that restrict agricultural yield. These pressures are expected to worsen as a result of climate change, posing even greater threats to global food security. Earth remote sensing (ERS) using unmanned aerial vehicles is operational monitoring of the state of fields, the quality of processing of fallow lands; provides control of the degree of weediness of fields during the period of spring fieldwork, which makes it possible to rationally distribute agricultural machinery for closing moisture, intermediate treatments and pre-sowing chemical treatments sowing quality control; monitoring the vegetation index makes it possible to construct effective schemes for plant feeding, as well as effectively distribute agricultural machinery during the harvesting period, depending on the degree of crop maturation. The yield mapping system allows evaluating the effectiveness of precision agriculture techniques, making it possible to accumulate data on productivity zones, considering the actual yield.
