This map is part of the 2014 OECD atlas on the Sahara and the Sahel, published under the title An Atlas of the Sahara-Sahel.
The map shows the project to build the Trans-Saharan gas pipeline, also known as NIGAL, which would connect Nigeria's gas reserves with Niger and Algeria, crossing the Sahara desert. This project was first mooted in 1971, although it was not until 2002 that it began to take shape after the Nigerian and Algerian national oil and gas companies signed an agreement.
The map shows with a dotted line the planned route of this pipeline. Given the stability issues in the region, the map also shows all the hotspots in 2014: Boko Haram in northern Nigeria, MEND in the Niger Delta, the Tuareg area, and the conflicts in Libya.
In 2026, the project is still underway and an estimated 60 % of the route is already built, although there would still be more than 1,000 kilometres left in Niger, as well as several connection problems in the border regions. Once built, it would be capable of transporting 30 billion cubic metres of natural gas to Europe annually. This would amount to around 10 % of the EU's current gas consumption.
