This research on climate change and the effects that can be caused in dry areas irrigated represented the most important human activities concentrated which agriculture is a source of food, especially cereals (rice and wheat) as field crops president by decreasing indicators began in production quantities and space threaten most of the land in the project Al.

kifll- Al.Shinafiyah ensured.

The search adopted the use of (GIS) to analyze the variation in climate change time periods spread between (1970, 2010), by drawing maps of elemental change the heat and rain and discuss the reasons that resulted from this climate change for the region studied.

The research concluded that the results are grouping by impact, as follows: - Climate change has caused problems of its effects are reflected clearly on the dry ranges increased markedly as a result of the apparent change in rainfall, especially in recent times and temperatures.

- Climate change contributed to a direct contribution to reducing water revenue which led to the deprivation of large tracts of farming as a result of realized water deficit of the area studied.

- Formed the ancient irrigation methods (flood irrigation) with forfeit lack of water revenue factor contributed significantly to soil salinization, which impacted negatively on productivity decrease in cultivated areas as well as the loss of areas of productive agricultural land in the region
