The interesting aspect of buildings like this is the need to tailor the design to the local environment. Humidity can be dealt with through careful consideration of airflow and heating.
Looking up Earthships can be a good starting point (though many of those are desert climate focused as well, it's not a necessity) for further research.
For example, I live in northern New England, which is heavy on trees and light on sand.
That's why our typical "vernacular architecture" is log cabins, not mud brick structures. Different advantages and disadvantages. Different construction process. Different materials. But still more sustainable than concrete.
