annual relative humidity is low with only 24%. The sky is clear all year and cloudy days are very rare. Thereby, the solar irradiation is among the highest found on the planet and the annual sunshine duration is estimated between 3,700 h and 4,000 h. In Salah is often quoted as one of the hottest spots worldwide. With Adrar and Reggane, In Salah forms the "Triangle of Fire" as local inhabitants say due to the extreme desert heat that bakes the region from May to September. Transport Air flights via In Salah Airport connect the town with the capital Algiers and other major cities in Algeria. The Bus station of In Salah hosts buses going to the north and south. There is a hotel, a restaurant, an internet cafe and two camping sites located in the city and surrounding area. The town lies at the junction of the Trans-Sahara Highway (also known as the N1 national highway), which leads north to Ghardaïa and Algiers and south to Tamanrasset, and the N52, which leads west to In Ghar and Reggane. Economy Aside from oil and gas reserves, the primary economic activities of In Salah are agricultural in nature with irrigation being supplied by artesian wells. The oasis has over 200,000 date palms. The chief produce are dates, fruits and vegetables. Fruit and vegetable gardens, as well as palm groves, flank the village on its southern and western edges. These groves are protected from the always advancing sand by hedges. In Salah is also a centre for nomadic Tuareg. The In Salah oil and gas fields are home to the In Salah Project, a major component of which includes a facility to remove CO2 from the gas produced. The CO2 is then re-injected into an underground formation. Historically, In Salah was formerly a trading town which dealt in slaves, ivory and gold from the south. These goods were exchanged with European goods from the north. In February 2016, BP announced further project start up at In Salah Southern Fields. In Salah Gas, a joint venture between Sonatrach, BP and Statoil today announced the start-up of its Southern Fields project. In Salah Gas was the first project in the world to be environmentally certified to the ISO 14001 standard. The ISO 14001 management system development and implementation was conducted by Sonni Gopal.
