4. Environment

The area is semi-arid, with an average rainfall of 1,001 to 1,500 millimeters. The annual

rainfall averaged 1,070.5 milliliters in 2021. (Data from the Meteorological Station:

Meteorological Department). The terrain is gentle. The elevation of the plateau ranges from 101
to 500 meters. The depth of the soil is greater than 20 cm. Fine-grained clay is the texture of the

topsoil. Loam and silty clay texture is in the subsoil. Organic matter levels are moderate (1-3
percent). It is impossible to utilize groundwater. The water quality is unpurified, yet the surface

water is moderate. Because of the salinity of the water, it can only be used for agriculture. As a

result, it is a significant issue in agriculture. Only a few types of crops can be produced as a result,
and yields are poor.
