Abstract

Less than three percent of the planet's water is fresh. habitat in the macro sense depend on this water. Over the past few decades, due to population growth, agricultural expansion, industrial growth, climate change and successive droughts, human access to water has steadily declined, threatening the survival of the status quo and the sustainability of human life and civilization. This damage has attracted the attention of brokers and researchers to water security. South Khorasan province in eastern Iran is inherently a low-rainfall province with a hot and dry climate and has been involved in successive droughts and over-extraction of groundwater reservoirs for the past two decades. Has resulted. The present article, which is applied and the methodology is explanatory-analytical, and its findings are collected by the library method (books, publications and the Internet) are based on the hypothesis that in recent years, rainfall has decreased and aquifers in the region have decreased. It is associated with an increase in the number of disputes and lawsuits. The results showed that the increasing complexity of increasing water abstraction, declining reservoirs, decreasing rainfall, population growth along with government policies related to the expansion of agriculture has led to increased tensions, conflicts and lawsuits and has affected the province's water security.
