Administration and economy
editBilma is the administrative seat of the Bilma Department, covering some 670,000 km2 (260,000 sq mi) of north eastern Niger. While it continues to produce salt in large natron salt pans, and this salt is still sold for livestock use throughout west Africa. Tourism (based out of Agadez and the Aïr Mountains some 560 km (350 mi) to the west) is of growing importance.

The town lies deep in the heart of the Sahara Desert, more precisely in the Ténéré, a hyper-arid desert region lying over northeastern Niger and western Chad, and as such is extremely dry, averaging only 12.7 mm (0.50 in) of measurable precipitation annually. Bilma is also hot during the "winter" months and extremely hot during the summer months and for prolonged periods of time.

The record high temperature is 48.2 °C (118.8 °F) on June 23, 2010.[3]

History
editThe poet Abu Ishaq Ibrahim al-Kanemi was born in Bilma in the 12th century.
During French Colonial rule, Bilma was the site of a major—if isolated—military post at Fort Dromard. After independence, the isolation of Bilma made it the destination for disgraced officials under the authoritarian regime of Seyni Kountché, and a prison was built there by the government. Political leaders were held there in the 1980s, such as Sanoussi Tambari Djakou, today president of the PNA-AL, a Nigerien political party.
In 1989, UTA Flight 772 crashed into the desert near the town after a bomb exploded on board, killing all 170 people aboard.
