Life without water is almost impossible anywhere on the planet earth.
Yemen is one such country where there is no permanent river or lake and the only source of water is those season river valleys called wadis (in certain Arabic-speaking countries a valley, ravine, or channel that is dry except in the rainy season).
This leads people to construct their homes above the valley to make the most of these temporary water resources.
Haid Al-Jazil is one such place in Yemen, a village, which looks astonishing in its unique form.
The buildings cling to the hillside or stand on the plateau, at a height of 100 or 200 meters above the level of the valley and many of them hang above the rocks.
These adobe structures need to be constantly repaired particularly after the summer rains that tend to wash away the mud coatings and weaken the structure.
The landscape surrounding Haid Al-Jazil, is comprised of vast deserts and each house consists of mud bricks with wooden floors that separate one story from another.
The structures of these houses are as innovative as they are sophisticated.
In a desert country located on the southern tip of the Arabian Peninsula, bordered by the Red Sea and the Bab-el-Mandeb Strait in the west, Saudi Arabia in the north and Oman in the east, Haid Al-Jazil is visual treat, a village perched entirely on a boulder.
People here live in densely built towns and villages centered on traditional watering stations along the wadis.
