La présente analyse de situation a été réalisée pour éclairer les réponses à plusieurs résolutions formulées lors du 5 Congrès mondial de la nature en 2012, concernant l'état critique des grands vertébrés d'Afrique centrale et de l'Ouest.

Building on the experience of Holcim Lebanon in rehabilitating one of its degraded quarries after excavation activities, this report will provide guidelines for rehabilitation practices in Lebanon and the Mediterranean. It will suggest milestones towards a successful rehabilitation process and discuss the challenges and constraints facing restoration initiatives while highlighting the main elements and lessons learned for future rehabilitation attempts in limestone quarries. 

The extraction of live coral to burn and produce "white lime" or "chokaa" has a long history in Tanzania, yet in many areas it is believed that this practice has reached unsustainable levels and is considered to be one of the main contributors to reef and forest degradation along the coast. This assessment was developed to describe the size, geographic extent and socioeconomics of the coral mining and lime production industry within the buffer zone of Mnazi Bay-Ruvuma Estuary Marine Park.

This report was produced by the IUCN Secretariat in response to a direct and specific request from the IUCN Thailand National Committee. It is intended to provide an independent scientific assessment of possible impacts of the proposed Mae Wong Dam and associated mitigation measures.
