The Sahara (Arabic: الصحراء الكبرى‎, Aṣ-Ṣaḥrā´ al-Kubrā, "The Great Desert") is the world's largest hot desert and second largest desert, after Antarctica. At over 9,400,000 square kilometres (3,600,000 sq mi), it covers most of Northern Africa, making it almost as large as China or the United States. The Sahara stretches from the Red Sea, including parts of the Mediterranean coasts, to the outskirts of the Atlantic Ocean. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna that composes the northern region of central and western Sub-Saharan Africa.

Some of the sand dunes can reach 180 metres (590 ft) in height. The name comes from the Arabic word for desert: (صَحراء ṣaḥrāʾ [sˤɑħrɑːʔ] ( listen)).

The Sahara's boundaries are the Atlantic Ocean on the west, the Atlas Mountains and the Mediterranean Sea on the north, the Red Sea on the east, and the Sudan (region) and the valley of the Niger River on the south. The Sahara is divided into western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Air Mountains (a region of desert mountains and high plateaus), Ténéré desert and the Libyan desert (the most arid region). The highest peak in the Sahara is Emi Koussi (3,415 m/11,204 ft) in the Tibesti Mountains in northern Chad.

Raymond Paul "Ray" Mears (born 7 February 1964) is an English woodsman, instructor, author and TV presenter. His TV appearances cover bushcraft and survival techniques, and he is best known for the TV series Ray Mears' Bushcraft, Ray Mears' World of Survival, Extreme Survival, Survival with Ray Mears, Wild Britain with Ray Mears and Ray Mears Goes Walkabout.

Mears grew up in Kenley, Greater London, and the North Downs, where he discovered a countryside abundant with wildlife. Educated at Reigate Grammar School, a co-educational independent school in Reigate, Surrey, he learned to track foxes in the forest at a young age. As a boy, he desired to sleep out on the trail, but unable to afford camping equipment, he resorted to setting up camp using what he could find in his surroundings.

Mears's enthusiasm for his subject, combined with his broad knowledge of survival and the uses which may be made of plants, trees and other natural materials found in woodland, forest or desert, have made him a popular figure in TV broadcasting in the UK.^{[citation needed]} He has travelled extensively across the world for his TV series and has learned survival techniques from the indigenous peoples he has met. In his programmes he demonstrates his knowledge of the wild, how to find food from seeds, berries, roots and other growing things, and how to survive by constructing temporary shelters, fires and canoes from natural materials.

Hossam Ramzy (born in Cairo, Egypt) is an Egyptian percussionist and composer. He has worked with Western artists like Jimmy Page and Robert Plant as well as with Arabic music artists like Rachid Taha and Khaled.

Ramzy was born into a wealthy Cairo family. He began playing the darbuka and tabla at an early age. He moved to Saudi Arabia for a time and learned traditional Bedouin music styles. In the 1970s he moved to London and began playing with saxophonist Andy Sheppard. His collaborations with jazz musicians earned him the nickname "The Sultan of Swing". In 1989 he worked with Peter Gabriel on the soundtrack to Martin Scorsese's The Last Temptation of Christ. This brought him to the attention of artists such as Frank Asher and the Gipsy Kings.

In 1994 he returned to his roots and formed a ten piece Egyptian ensemble that performed on the album No Quarter: Jimmy Page and Robert Plant Unledded. Ramzy and his ensemble also gained exposure by touring with Plant and Page throughout 1995 in support of their album. The next year Ramzy released the first of three collaborations with English arranger Phil Thornton, Eternal Egypt. The success of Eternal Egypt's blend of Arabic music prompted the follow up albums Immortal Egypt and Enchanted Egypt. In 1998, he performed with Rachid Taha, Khaled and Faudel at their 1,2,3 Soleils concert and backed Khaled again for the Claude Challe album Flying Carpet.
