Landscape Evolution, Neotectonics and Quaternary Environmental Change in Southern Cameroon PALAEOECOLOGY OF AFRICA PALAEOECOLOGY OF AFRICA International Yearbook of Landscape Evolution and Palaeoenvironments 31 31 International Yearbook of Landscape Evolution and Palaeoenvironments 31 Runge Founded in 1966, the internationally recognized and acclaimed Series ‘Palaeoecology of Africa’ publishes interdisciplinary scientific papers on landscape evolution and on former environments of the African continent. Beginning with topics such as changes in climate and vegetation cover, the papers expand horizons and interconnections to various types of environmental dynamics from the Cainozoic up to the present; moreover, the aspect of human influence since the Late Quaternary is related to many of the areas studied. Cameroon Southern in Change Environmental Quaternary and Neotectonics Evolution, Landscape Volume 31 presents four comprehensive papers on long‐ and short‐term processes of landscape evolution (geological history, neotectonics and proxy Quaternary alluvia), as well as a recent regional perspective on environmental problems in Southern Cameroon. The book acts as a showcase for successful North‐South cooperation and capacity building for empowering African Universities. It is problem oriented and applied, and illustrates how scientific and interdisciplinary cooperation can work. In the framework of the German Research Foundation’s (DFG, Deutsche Forschungsgemeinschaft) funded "Rain Forest Savanna Contact" project (2003‐2009) two abbreviated English versions of PhD theses are here published, one by J. Eisenberg on neotectonics and the other by M. Sangen on river sediments in rain forest‐savanna transitional zones. Complementary articles are an introduction on geological history, by B. Kankeu et al. and a paper on environmental risks by M. Tchindjang et al., together these complete the results of this joint German‐Cameroonian research project. This book will be of interest to all concerned with ecosystems dynamics, tropical forests, savannas and related development problems of Third World countries, especially regional planners, ecologists, botanists, earth scientists and students of the Quaternary (e.g. LGM and Holocene ecosystem dynamics, Global Change). It will be valuable for advanced undergraduates and postgraduates as a reference for new research articles on the topic of long‐term geologic‐tectonic and Quaternary landscape evolution in an up‐to‐now not well explored marginal area of the Western Congo basin.

In fact, this cooperation is an ongoing and effective one. In 2003, the German Research Foundation (DFG, Deutsche Forschungsgemein- schaft) agreed to establish an interdisciplinary research group on “Ecological and Cultural Change in West and Central Africa” composed of archaeologists, palaeo- botanists and physical geographers from the Universities of Tübingen and Frankfurt. Aside from sharing common scientific research interests, it was and it remains crucial for Germany’s research politics to have a strong focus on intercultural cooperation and academic capacity building of local partners. In the framework of the “Rain Forest Savanna Contact” subproject (in German “ReSaKo”) a close and fruitful relationship and cooperation developed in particular between the University of Yaoundé I and the University of Frankfurt. An outcome of this subproject were two PhD theses, one by Joachim Eisenberg on ‘neotectonics and landscape evolution’ in Southern Cameroon, the other, by Mark Sangen, on the ‘Quaternary environment’ as evidenced by alluvia in river valleys in the rain forest and along transitional areas into savannas. In 2009 and 2010, respectively these theses were formally published in German in par- tial fulfillment of PhD requirements. Thereafter, it occurred to me that these valuable studies should be made available to the wider international scientific community. For this reason, I proposed in 2011 to re-publish the two PhD works in condensed English versions. Within the framework of the ‘Palaeoecology of Africa’ (PoA) annual series, it was possible to publish these extensive papers, which normally would have had no place in scientific journals. Underlining and reinforcing the excellent cooperation we have enjoyed with our colleagues from Cameroon, I invited Boniface Kankeu to con- tribute an introductory chapter on the Palaeozoic evolution of the study area. Finally, Mesmin Tchindjang, who is strongly focused on applied questions and development problems (‘environmental risks’) of Cameroon, was asked to contribute a longer paper looking at present and future challenges of the wider Cameroonian study area. By bringing these issues together in this book, we have managed to achieve one of our goals: to form a “linkage” between basic scientific research and problem-oriented applications. Within the University of Frankfurt Physical Geography working group, all man- uscripts have been reviewed and corrected several times. The English was consistently checked and corrected by Dr. Dawn Frame (C.N.R.S. Montpellier).

When this small watershed was set up, no similar survey of input/output hydrobiogeochemical fluxes in granitoid rocks in stable cratonic environment was available, to our knowledge, on any site close to the Equator. Moreover, this is the first attempt, world-wide, to combine different ap- proaches in hydrology, (bio)geochemistry, mineralogy, crystallography, microbiology, geophysics and pedology. Re- search is based on (1) regular hydrobiogeochemical surveys in various water reservoirs of the SEW ecosystem (atmospheric deposits, groundwater and stream), (2) surveys related either to the organisation and composition of dif- ferent reservoirs in the superficial layers (basement rocks,

This project, which has been initiated to develop a 1 billion barrel hydrocarbon reserve within Chad, will result in the conveyance by pipeline of some 225 000 barrels per day of heavy crude oil through Cameroonian territory and its discharge at a marine terminal located within Cameroon’s coastal waters. Clearly, the issue of risk associated with potential pipeline product spills arises and, therefore, justifies the need for the NOSCP.

Above-ground biomass logged was quantified using allometric equations. The surface area of logging roads and log yards were quantified and used in the determination of above-ground biomass affected by these infrastructures based on a national reference baseline value for the forest zone of Cameroon. A comparative analysis revealed that 50% of potentially exploitable commercial tree species were effectively harvested with a harvesting intensity of 0.78 trees ha-1 representing an average above-ground biomass of 3.51 Mg ha-1.

    Integrated Agricultural Systems for the Humidtropics, a CGIAR Research Project Consultancy Report on Vegetable Seeds Baseline survey for setting up smallholders’ sustainable vegetable seed supply and distribution system in humid tropics areas of Cameroon Team Members Tata Precillia Ijang (Team leader) Dr Ngome Francis Godswill Ntsomboh Ntsefong Ngayong Joseph Wirngo December 2013 Executive Summary The Cameroon seed sector is developing slowly and steadily and there is political will through government legislation and requirements to foster the development of the sector with a view to boosting the agricultural sector as well as stimulating the economy as a whole. The seed sector activity is regulated by law N o 2001/014 of 23 rd July 2001 relating to seed production and marketing and its instruments of application. Decision N o 541/MINADER/SG/DRCQ/SDRSQV of 7 th September 2006 on the homologation of official technical regulation of quality control of certain vegetable seeds complements the law of July 2001 and specifically applies to the production, importation and quality control and marketing of vegetable seeds. The public sector has a definite contribution to promote the development of the seed sector in Cameroon. Through the Department of Quality Regulation and Control of Inputs and Agricultural Products of the Ministry of Agriculture and Rural Development, the state ensures regulation of seeds and vegetable quarantine as well as the breeding of various species of seeds. At present this department controls one national breeding centre and ten regional ones that supply seeds to various stakeholders of the seed sector in Cameroon. The role of public sector is mainly catalytic in initiating seed production, quality control, seed certification, notification and registration of varieties and other regulatory systems.

  • Important Progress Towards Elimination of Onchocerciasis in the West Region of Cameroon Guy-Roger Kamga1,2,3*, Fanny N
    Kamga et al. Parasites & Vectors (2017) 10:373 DOI 10.1186/s13071-017-2301-7 RESEARCH Open Access Important progress towards elimination of onchocerciasis in the West Region of Cameroon Guy-Roger Kamga1,2,3*, Fanny N. Dissak-Delon1,2,4, Hugues C. Nana-Djeunga2,5, Benjamin D. Biholong1, Stephen Mbigha Ghogomu6, Jacob Souopgui4, Joseph Kamgno2,5 and Annie Robert3 Abstract Background: After more than a decade of community-directed treatment with ivermectin (CDTI) in the West Region of Cameroon, epidemiological evaluation conducted in 2011 showed that onchocerciasis endemicity was still high in some communities. The conceptual framework for onchocerciasis elimination recommends in such case, to conduct additional phase 1A surveys at intervals of three to four years. Therefore, to assess the progress made towards the elimination of onchocerciasis in the West CDTI projects, we conducted a cross-sectional survey in May 2015 in 15 unevaluated communities where the highest baseline endemicity level were found in 1996. All volunteers living for at least five years in the community, aged five years or more, underwent clinical and parasitological examinations. Individual adherence to ivermectin treatment was also assessed. Analyses of data were weighted proportionally to age and gender distribution in the population. Results: The mean age was 28.4 ± 22.2 years and there were 55% of women among the 2058 individuals examined. The weighted prevalences were 5.5%, 2.1% and 1.7% for microfilaridermia, nodule and cutaneous signs, respectively. The weighted microfilaridermia prevalences varied from 4.0 in 5–9 years old to 11.6% in 40–49 years old.

    Rufford Small Grant, Dossier 16004-1, Podostemaceae, J.-P. Ghogue. Identification of suitable sites for translocation of endemic Podostemaceae threatened by dams in the Sanaga River (Cameroon) DETAILED REPORT Presented by: NGANSOP TOUNKAM Marlène FORBI Preasious FUNWI GHOGUE Jean-Paul August 2016 Rufford Small Grant, Dossier 16004-1, Podostemaceae, J.-P. Ghogue. EXECUTIVE SUMMARY This project, categorized under Wetlands was carried out in the Sanaga River in Cameroon where Podostemaceae, submerged freshwater plants, are threatened by the construction of dams. This report summarizes field activities and scientific findings to identify sustainable recipient river sites for the potential translocation of the Podostemaceae. The survey covered a period of five months. During this period, water samples of nine rivers in Cameroon (Sanaga, Afamba, Kelle, Nyong, Lep Riton, Dibang, Ngwei, Mbam, Eding) were collected. For each of the different stations, two water samples were collected for physico-chemical and biological analysis at the Hydrobiological laboratory of the University of Dschang. Temperature, altitude, and geographical coordinates of each station were recorded. Multivariate analysis of variance was done to compare the nitrate, phosphate, total dissolved solids, redox potential, conductivity and pH of the Afamba, Kelle, Nyong, Lep Riton, Dibang, Ngwei, Mbam and Eding rivers with those of the Sanaga River. Suitable Recipient Rivers were to be selected based on the relative similarity of their water with those of the Sanaga and their size. Based on their similarity, the results of this study revealed that there were no significance differences between waters of the Kelle and those of the Sanaga at Edea for the above mentioned parameters.
