الملخص EN

The research problem revolves around the phenomenon of climate changes, the reasons for their occurrence, and their effects on agricultural lands, agricultural production and water resources in the Asir region.

Therefore, the research aims to determine the expected effects of climate changes on both agricultural lands and the production of the most important agricultural crops, and water resources.

The research relied on the descriptive analytical method, to determine the current situation and the future vision of climate changes and their effects on agriculture and agricultural development in the Asir region.

The most important research results were as follows: 1- The annual temperature rates during the period (1985-2017) are heading towards an increase, with a decrease in the amount of rain and an upward trend in all climatic stations of the study area.

2- Decreasing the area of high quality agricultural lands.

3- Climate changes will negatively affect the production of field crops, as well as the rate of self-sufficiency, and climate changes are expected to affect water resources..

The research recommends several recommendations, as follows: - Establishing agricultural development programs that take into account the expected climate changes and avoiding their negative effects 1 - Devising new varieties that bear high temperatures, salinity and drought and their short growing season to reduce the water needs needed for them can prevent the expected negative effects 2 - Reducing the area of wasteful crops in its water consumption.

3- Applying better methods in land management.

4- Completing the severe shortage of available data and information on the negative effects of climate change on the various sectors of development in the study area, and establishing a complete database to make it available for study and research.
