The Marosakabe cave system is a cave in Marosalaza region, Madagascar, the longest in Africa. [1]
The cave is situated in northwestern part of Madagascar in the Mahajanga Province in Namoroka National Park, in a Tsingy area. It is characterized by an extremely high number of fractures, with very pure jurassic limestone, and the void density is very high. [2]
The cave has been explored since 2008 under the coordination of Jean-Nicolas Delaty and Eric Sibert. After 11 expeditions in the remote area, 113 km of cave passages have been explored and surveyed (as of 2018), making it the longest cave in Africa [2] [3] and the 18th longest cave system in the world.
Ankarana Special Reserve is a protected area in northern Madagascar created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about 2,000 millimetres (79 in), the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion.
Morondava is a city located in Menabe Region, of which it is the capital, in Madagascar. It is located in the delta of the Morondava River at 20°17′5″S44°19′3″E. Its population as of the 2018 census, was 53,510.

The Madagascar dry deciduous forests represent a tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of endemic plant and animal species but has suffered large-scale clearance for agriculture. They are among the world's richest and most distinctive dry forests and included in the Global 200 ecoregions by the World Wide Fund. The area is also home to distinctive limestone karst formations known as tsingy, including the World Heritage Site of Bemaraha.

The Vazimba, according to popular belief, were the first inhabitants of Madagascar. While beliefs about the physical appearance of the Vazimba reflect regional variation, they are generally described as smaller in stature than the average person, leading some scientists to speculate that they may have been a pygmy people who migrated from the islands that constitute modern-day Indonesia and settled in Madagascar over the course of the period between 350 BCE–500 CE. Scientific evidence confirms the first arrival and subsequent increase of human settlers on the island during this period, but the pygmy theory has not been proven.
