About this book

Language: English with a French contribution and trilingual abstract in English, German, and French

This report summarises three different speleological projects to Madagascar. Besides the successful 2003 Dutch expedition to the Tsingy de Bemaraha, two previous German projects to the Karst of South Narinda (NE of Majunga, 1991 und 1992) and Namoroka (SW of Majunga, 1992) are presented in detail.

During the 2003 Dutch expedition, fourteen caves with a total passage length of 7228 m were discovered and surveyed in Bemahara National Park, including two major cave systems: Zohy Krisitaly (3355 m long) and Zohy Malalaky (2166 m long).

The 1991/92 German expeditions yielded 8678 m of cave passage from 9 caves: 4630 m long Anjohiambovonomby was explored in the Namoroka karst; 3896 m resulted from the South Narinda karst, including the 2104 m long Anjohikely; and in the central highlands of Madagascar 152 m long Grotte Aübert was discovered on Mount Ibity.
