New Records of the Togo Toad, Sclerophrys Togoensis, from South-Eastern Ivory Coast
Herpetology Notes, volume 12: 501-508 (2019) (published online on 19 May 2019) New records of the Togo Toad, Sclerophrys togoensis, from south-eastern Ivory Coast Basseu Aude-Inès Gongomin1, N’Goran Germain Kouamé1,*, and Mark-Oliver Rödel2 Abstract. Reported are new records of the forest toad, Sclerophrys togoensis, from south-eastern Ivory Coast. A small population was found in the rainforest of Mabi and Yaya Classified Forests. These forests and Taï National Park in the western part of the country are the only known and remaining Ivorian habitats of this species. Sclerophrys togoensis is confined to primary and slightly degraded rainforest. Known sites should be urgently and effectively protected from further forest loss. Keywords.

Box CT2121 Cantonment, A POLICY BRIEF ON Accra-Ghana Tel: 030-290 0730 THE POTENTIAL FISCAL CONTRIBUTION facebook: Africa Centre for Energy Policy SPONSORED BY: OF THE SHEINI IRON ORE DEPOSITS IN twitter@AcepPower www.acepghana.com NORTHERN GHANA Executive Summary In the wake of increasing global economic challenges amidst unprecedented political events that may have significant impact on the world economies, Ghana is again blessed with an iron ore mine which is yet to be developed. The mine has the potential to expand the country’s economic progress and have trickling down effects of social progress and sustainable development for its peoples. It therefore becomes imperative to understand the extent of fiscal impacts that Ghana’s Sheini iron ore project is likely to bring. It is against this backdrop that the Africa Centre for Energy Policy (ACEP), through its partnership with WACAM under the auspices of OSIWA, undertook this fiscal benchmarking study. The approach to the study was quantitative. Using an excel fiscal model, the Sheini iron ore project was situated within the geological and project context of Guinea’s Simandou iron ore project to compare Ghana’s mining fiscal policy against the fiscal provisions of the contract between the Government of Guinea and Simfer S.A. The purpose was to determine the level of fiscal convergence between the two projects and use findings as an important guide for improving on the fiscal take from Ghana’s Sheini iron ore project. The following were the key findings about the competitiveness of Ghana’s mining fiscal terms and how equitable they are in ensuring that the government and its people benefit from the mining sector: From Government Perspective 1. -

For example, a deadline to apply for a scholarship can be easily missed if it is not posted to the community at a proper time. As a result, and for better and faster communication among the geological society of Africa, the GSAf will use a Gmail group ([email protected]) to facilitate the communication between society members. Some advice and rules: Since any member can post and all the members will receive your message, please do not overload the society by un-related news. Post only important news that wants immediate action from members. Improper messages can lead its owner to be blocked from posting. -
