Iran is facing unprecedented challenges in securing water and food for its growing population, which is projected to reach 92 million by 2050. These challenges are due not only to Iran’s semi-arid climate and declining precipitation over the past decade, but also to mismanagement of water resources.
Water supply and food security will pose a major challenge in the coming years, which many government officials refer to as a human security issue. Both the country’s natural climatic situation and the government policies in managing its limited water resources over the past few decades have exacerbated this challenge.
Uncontrolled use of groundwater resources in the regions with insufficient amount of surface water (rivers and lakes) stands out as another challenge. Use of illegal wells for groundwater extraction is a major issue. Despite the legal regulations on wells, the problem related to illegal wells cannot be solved because of the inadequate sanctions and inspection. The groundwater resources are subject to intense use for agriculture purpose. Because of over-extraction, most of the groundwater resources are under the threat of extinction.
It is essential to take immediate measures to prevent potential water shortage. Thus, demand-oriented management should be the focus rather than supply-oriented management. Demand-oriented management is provided by efficiently using water resources through limiting demand on water, and setting institutional, economic and administrative incentives to save water. It is essential for water resources management to be flexible and effective enough to adapt to changing climate conditions, dry spells, and new precipitation patterns.
