Bilma is an oasis town and commune in north east Niger with a population of around 2,500 people.[1] As of 2011, the commune had a total population of 6,481 people.[2] It lies protected from the desert dunes under the Kaouar Cliffs and is the largest town along the Kaouar escarpment. It is known for its gardens, for salt and natron production through evaporation ponds,[3] date cultivation, and as the destination of one of the last Saharan caravan routes (the Azalai, from Agadez). On June 23, 2010 in Bilma the highest temperature ever in Niger was recorded at 48.2 °C (118.8 °F).

Population[edit]

Its population is mostly Kanuri, with smaller Toubou, Tuareg, and Hausa populations, the last being a reminder of Bilma's role as a key stop in the Trans Saharan trade.

Administration and economy[edit]

Bilma 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 east) is of growing importance.

Climate[edit]

Bilma features a hot desert climate. The town lies deep in the heart of the Sahara Desert, more precisely in the Ténéré, an hyperarid 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 extremely warm during the "winter" months and extraordinarily hot during the summer months and for prolonged periods of time. Averages high temperatures in "winter" months range from 24 to 35 °C (75 to 95 °F) and from 38 to 46 °C (100 to 115 °F) during summer months.

History[edit]

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. During French Colonial rule, Bilma was the site of a major—if isolated—military post at Fort Dromard.

In 1989, UTA Flight 772 crashed into the desert near the town after a bomb exploded on board.
