Summary | Le taux d'érosion de Madagascar est le plus élevé du monde. L'érosion massive sur le flanc des collines se manifeste par des ravins appelés "lavaka". L'auteur signale les causes possibles de ce processus. Puis il note que les "lavaka" peuvent devenir des îlots forestiers qui ont un rôle positif dans l'évolution de la diversité biologique de Madagascar. |
