This paper analyses analysis current and future dependence of agriculture, industry, oil and gas sector on water supply in Kazakhstan under varying socioeconomic and climate change scenarios. To conduct the scenarios analysis, a multiple linear model was used; the model has been widely used to examine complex water systems in the water resource planning sector all around the world. The paper results show that by 2050 total water demand under normal weather conditions could increase from m3 in 2015 to m3 under sustainable use scenario, to m3 under current trends (CT) baseline scenario, and up to m3 under the more resource intensive scenario, however, the future water demand may be affected by environmental changes. | Towards a low-carbon economic sustainable development Scenarios and policies for Kazakhstan -
