Abstract

The present study focused on rainfall levels and their morpho-climatic impact on agricultural land erosion in the Daquq district. Consequently, it is imperative to preserve and protect the soil. However, the study area is currently facing climate change, which poses a significant threat. As a result, the soil is vulnerable to various risks that negatively impact its fertility and jeopardize agricultural production. The soil is strongly influenced by variations in precipitation rates and temperature in the atmosphere due to its direct connection with the environment. The effects of climate change on soil are gradual and occur over an extended period of time. However, they have a substantial influence on soil quality and agricultural crop yields. Nevertheless, the plant might be more rapidly impacted than the soil itself. The research area's findings were obtained by using Landsat  visualization and monitoring the impact via the correlation of Daquq climate station data with the precipitation levels for the year 2022 AD. The analysis of erosion levels revealed three categories of risk for agricultural soil erosion: low risk, medium risk, and high risk. The majority of the study area (55.05% of the total area) was found to have low erosion soil, which is primarily used for agriculture and pastoral activities. This area is also characterized by the presence of surface water in the form of rivers and canals.
