Dams, Drought and Water Shortage in Today’s Iran

Iran has a long history of effective and sustainable water resource management under arid and semi-arid conditions. However, today the country is faced with serious challenges in the water sector, including rising water demand and shortages, declining groundwater levels, deteriorating water quality, and increasing threats to the environment and various ecosystems. If these issues persist, tragedy will be the inevitable result. Over the last three decades tremendous efforts have been made to supply water, primarily through an extensive program of development, with dam building at the forefront. This paper offers an introduction to the different factors and elements influencing the water balance in today’s Iran and presents a perspective on the trend of dam building in recent times.
