These Risks Are Predictable and Expectable for Water Resources

These Risks Are Predictable and Expectable for Water Resources


''ARMENIAN STATE HYDROMETEOROLOGICAL AND MONITORING SERVICE" SNCO has published data to what extent the agriculture and water resources of Armenia are vulnerable, if the air temperature increases by 1.5-2.0 degrees. The publication of the organization entitled “Hotter, drier, wetter. Face the future” particularly says, 

• The aggregate river course will be reduced by  6.7%  by 2030 and by 14.5% by 2070 and around 24.4% by 2100.

• Precipitation in the form of snow will be reduced by 7-11% by 2030 and by 16-20% by 2070 and by 20-40% by 2100.

• Because of the reduction of Lake Sevan balance main elements – evaporation, precipitation and surface flow, the current flow of Lake Sevan will draw up 220-250 million m3 instead of current 252 million m3. In case the air temperature increases 0.5 degree in the lake basin, the water volume will be added (reduced) by 70 million m3,  and in case of precipitation increase (reduction) by 5%, it will be added (reduced) by 37 million m3. In case of air temperature by 2 degrees and reduction of atmospheric precipitation by 10%, the evaporation from lake surface will be increased by  approximately 145 million m3 (115 mm) or 13.5%.

• The evaporation in different regions of Armenia will be increased by 3-5%, so in different regions of Armenia there will be observed lack of irrigation water by 8-15% if the current rate continues.
