One of the important issues that affect the lives of people on this planet is the availability of fresh water to meet people's needs and achieve food security.

It is no longer a secret that climate change has a tangible impact on water resources in quantity and quality, but this very important topic has been subjected to the interaction of scientific activity with political articles, some of which lack the possession of scientific research tools, which increases the load on academic researchers in studying this matter and reaching correct results that contribute to redrawing water management policies on solid foundations.

The Upper Euphrates Basin Developing Centre adopted a study in this field through a master's thesis supervised jointly by our colleague Prof. Dr. Ammar Hatem Kamel, Head of the Centre, the hypothesis was put forward that climate changes may not cause a decrease in the total rainfall during a certain period of time, but they cause distortion of the cycle of wet and dry years typical of a certain region.

The two weather stations of our research centre in Ramadi and our research station in the Haditha Dam monitored the frequency of rainfall, the largest monthly average in a hundred years, during this year 2022-2023, which is one of the dry years compared to the rates of discharge of the Tigris and Euphrates rivers, where the depth of rain recorded in cannes in the first of 2022 was 86.5 mm, and a rainfall depth of 56 mm was recorded in March 2023, and both of these depths are the largest in a hundred years in Anbar province.

A research was published in a refereed international journal within Scopus databases, and the United Nations publications on the occasion of World Water Day last week (22/3/2023) agreed, agreeing with our hypothesis above, but we emphasize that this very important topic requires more studies on broad scales that include different regions in order to reach more useful results, and there is no doubt that studies of this kind require serious funding to contribute to achieving water and food security in these very difficult circumstances.

Our research centre has prepared a plan to establish weather stations in different locations in Anbar province to enhance climate data and facilitate ways for researchers to study rain and floods and reach results that can be adopted in the formulation of policies for the management of our water resources in order to achieve food security.
