Interactions Between Changing Climates and Land Uses: The Case of Urmia Lake, Iran

Abstract

Iran is experiencing rapid population growth coupled with the negative impacts of global warming and land-use change. These impacts pose significant challenges for water managers and planners trying to match supply and demand. The twin challenges of land-use management and planning for climate change are exemplified in the case of Lake Urmia-situated in a closed basin in northwestern Iran. The basin supports agriculture from water stored in several reservoirs. Lake Urmia was once the largest saltwater lake in the Middle East and North Africa. It has recently become an environmental concern due to shrinking by 80% within the last 30 years. The dropping water level is exacerbated by a combination of declining precipitation and land conversion practices. Water loss provokes severe socioenvironmental consequences (including chronic health impacts, child mortality risks, and agricultural threats) that are similar in magnitude to those seen in the Kazakhstan-Uzbekistan Aral Sea disaster. This chapter explores the interactions M. Ghanian (✉)
