Water-resource substantiation of strategic planning in the regions of the Ob-Irtysh basin

Abstract

The paper substantiates the need to conduct water assessment for the strategic planning documents of the regions, including the elaboration of strategies and the forecasts of long-term socio-economic development of the Russian Federation. In this regard, we present the theoretical and methodological approach and the algorithm of such assessments. The approach is based on the landscape-basin principle of territory organization. On the example of the Ob-Irtysh basin regions, the assessing has revealed water availability in the territories, anthropogenic load, water intensity, water consumption forecast, and prospects for water resources use. They indicate local water shortage in some landscape provinces of Omsk Oblast with a total population of more than 130 thousand people. Within the boundaries of river basins, we have estimated the anthropogenic load of low and medium intensity and calculated water intensity of territories (municipal districts), including for different types of economic activity and yearly dynamics. These results have been also a basis for forecasting the prospective use of water resources for drinking, industrial, irrigation and agricultural purposes. Using the forecasts, we have developed scenarios of the water supply of the regions, considering water content (minimum, maximum and average) of the period.
