• Mega Water: A Pirate Map for Future Water Wars: The aquifers in Africa, however, which are some of the biggest in the world, are still largely under-exploite d. They have considerable potential, provided that their resources are managed on a sustainable basis. Because they generally extend across several state boundaries, their exploitation presupposes agreed management mechanisms in order, for example, to prevent pollution or over-exploitat ion by particular states. Mechanisms of this kind have begun to emerge in recent years. For example, in the 1990s Chad, Egypt, the Libyan Arab Jamahiriya, and Sudan established a joint authority to manage the Nubian aquifer system in a concerted manner. In their project concerning the Iullemeden aquifer, Niger, Nigeria, and Mali approved in principle a consultative mechanism for administering the aquifer system.

• Observe an animation of cave formation.: Over thousands of years, areas with limestone rocks can develop caves. Groundwater dissolves a network of tunnels in the rock. If the water table is lowered by a change in climate or tectonic uplift of the area, groundwater drains out of the tunnels, leaving the caverns exposed to air.
