Abstract
The article deals with the problem of improving the methodology of assessment and the choice of an effective way to increase the cadastral value of agricultural land. The developed method can be used to assess soil, water and air pollution on land allotment areas located on the territories of the considered areas with mining and metallurgical industries in Kazakhstan. The result of the proposed method is the ability to determine the coefficient of accumulation of hazardous and harmful factors of the industrial and environmental factors, its use will allow to establish the time of emergencies in the industrial and environmental situations. The results of studies on the assessment of crop contamination by heavy metals using the developed methodology and program allow to assess the damage and update land cadastral maps in the areas under consideration. Under these conditions, improvement of methods of assessment and selection of effective way to increase the cadastral value of agricultural land in the Republic of Kazakhstan cannot be implemented without establishing the sources and causes of pollution, organization of measures to reduce emissions, localization or elimination of the source of pollution. Only under such conditions high efficiency of costs for reclamation and involvement of unused and abandoned lands into agricultural turnover can be achieved.
