An arid Asian area is a region with low levels of rainfall and a scarce amount of water resources. However, there are several synonyms that can be used to describe this type of region. For instance, the term 'desiccated' can be used to describe an arid Asian area characterized by dryness or dehydration. Another synonym is 'barren', which refers to the region's lack of vegetation and plant life. Additionally, 'waterless' is another suitable synonym, as it describes the absence or scarcity of water in the region. Other synonyms include 'infertile', 'unproductive', and 'sterile', all of which describe the region's inability to support sustained growth and development.
