Optimization of Agricultural Land Use in Chimbay District of the Republic of Karakalpakstan Using GIS Technologies

Abstract

The article deals with the issue of optimizing the use of agricultural land. The negative impact of the environmental factors of the Aral Sea requires more work on the efficient use of agricultural land in the region. The focus of the research is on the efficient use of agricultural land based on the optimal placement of Agricultural crops. The main factor in optimizing the use of agricultural land is to reduce the resources spent on agricultural production and increase the productivity of agricultural products. Land use optimization work was carried out using GIS technologies and the results were mapped. Agricultural lands in the Chimbay district with complex ecological conditions were selected as a key object, and it was proposed to place crops based on 3 different solutions. Scenario maps for the placement of Agricultural crops were created using the ArcGIS program and its ArcPy application. Irrigated land for the key object was calculated as the amount and productivity of resources used for growing crops. Through the proposed optimal solution, the resources spent on crop production were reduced by 11% and yields were increased by 34%.  This optimization model will greatly help to improve the efficiency of agricultural land use with the correct placement of agricultural networks, taking into account environmental and economic factors.
