Russeifa

Russeifa no longer digs the mineral that made it, but it still lives on the scar. Jordan's official 2025 municipality estimate puts Russeifa at 490,347 residents packed into the Amman-Zarqa corridor, far above the older urban counts that still circulate online.

The official story starts with phosphate. Russeifa sits 614 metres above sea level in Zarqa Governorate, on the highway between Amman and Zarqa, and its early growth came from the phosphate deposits discovered there in the 1930s. What that history misses is the city's second life after extraction. Climate-Med's municipal profile says Russeifa now covers about 40 square kilometres, hosts more than 1,101 shops plus 146 factories and companies, and functions as a strategic checkpoint on the route from the capital to northern Jordan. In other words, the mine did not just create a company town. It created a dense corridor city that keeps absorbing people, commerce, and industry because it sits between two larger urban systems.

The harder truth is that Russeifa inherited the environmental bill along with the urban density. In July 2025, Jordan Phosphate Mines said its project to rehabilitate the former phosphate hills in Russeifa had reached 50% completion, with the company funding the work at JD24 million. Royal and local reporting says the project covers about 1,700 dunums of polluted former mine land, and by December 2025 the municipality had already started reviving a 125-dunum national park inside that larger rehabilitation push. That makes the city's present tense unusually clear: Russeifa is not simply growing because it is close to Amman and Zarqa. It is growing while trying to convert a mining legacy into habitable land, commercial frontage, and public green space.

This is phase transitions reinforced by commensalism and path dependence. The biological parallel is a mangrove. Mangroves colonize harsh edge zones, trap waste, and slowly turn unstable sediment into ground other organisms can live on. Russeifa does the urban version: it lives off the metropolitan current between larger neighbors while spending heavily to stabilize the damaged terrain that earlier growth left behind.
