The River Logone: a Mixed-Blessing to the Inhabitants of Mayo Danay
SYLLABUS Revue scientifique interdisciplinaire de l’École Normale Supérieure Série Lettres et sciences humaines Numéro spécial volume VII N° 1 2016 THE RIVER LOGONE: A MIXED-BLESSING TO THE INHABITANTS OF MAYO DANAY DIVISION, FAR-NORTH REGION OF CAMEROON TAKEM MBI Bienvenu Magloire National Institute of Cartography, P.O. Box 157, INC, Yaoundé [email protected] Abstract This paper sought to know if the constant supply of water to the River Logone, in a very low altitude area, from the wet tropical highlands in central Cameroon and the Adamawa plateau is a mixed- blessing to the inhabitants of Mayo Danay. Data was gathered through field enquiry and discussions with administrative authorities in October 2014. Results depict that a number of activities like farming, fishing, animal rearing and transport in the area depend on the River Logone despite that it is a source of floods and facilitates the spreading of malaria parasite. Conclusively, it is actually a mixed- blessing to the people, necessitating measures to make it less hazardous. Key-Words: Far North Cameroon, Floods, Mayo Danay, River Logone.

Review of River Fisheries Valuation in West and Central Africa by Arthur
Neiland and Béné ___________________________________________________________________________________ Review of River Fisheries Valuation in West and Central Africa by Arthur Neiland (1) & Christophe Béné (2) IDDRA (Institute for Sustainable Development & Aquatic Resources) Portsmouth Technopole Kingston Crescent Portsmouth PO2 Hants United Kingdom Tel: +44 2392 658232 E-mail: [email protected] CEMARE (Centre for the Economics & Management of Aquatic Resources) University of Portsmouth Locksway Road Portsmouth PO4 8JF Hants United Kingdom Tel: +44 2392 844116 1 E-mail: [email protected] 1 Dr Bene is now at the World Fish Center 1 Neiland and Béné ___________________________________________________________________________________ ABSTRACT This paper provides a review of the valuation of river fisheries in West and Central Africa. It is the general perception that compared to the biological and ecological aspects of river fisheries, this particular subject area has received comparatively little attention. Economic valuation is concerned with finding expression for what is important in life for human society. It should therefore be a central and integral part of government decision-making and policy. The paper starts with a review of concepts and methods for valuation. Three main types of valuation techniques are identified: conventional economic valuations, economic impact assessments and socio-economic investigations and livelihood analysis. On the basis of a literature review, valuation information was then synthesised for the major regional river basins and large lakes, and also used to develop a series of national fisheries profiles. To supplement this broad perspective, a series of case-studies are also presented, which focus in particular on the impact of changes in water management regime. Finally, the paper presents an assessment of the three main types of valuation methodology and a set of conclusions and recommendations for future valuation studies. -

Wetland Hydrodynamics Using Interferometric Synthetic Aperture Radar, Remote Sensing, and Modeling
WETLAND HYDRODYNAMICS USING INTERFEROMETRIC SYNTHETIC APERTURE RADAR, REMOTE SENSING, AND MODELING DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Hahn Chul Jung, M. S. Graduate Program in Geological Sciences The Ohio State University 2011 Dissertation Committee: Dr. Douglas Alsdorf, Advisor Dr. Ralph R.B. von Frese Dr. Kenneth C. Jezek Dr. C.K. Shum Copyright by Hahn Chul Jung 2011 ABSTRACT The wetlands of low-land rivers and lakes are massive in size and in volumetric fluxes, which greatly limits a thorough understanding of their flow dynamics. The complexity of floodwater flows has not been well captured because flood waters move laterally across wetlands and this movement is not bounded like that of typical channel flow. The importance of these issues is exemplified by wetland loss in the Lake Chad Basin, which has been accelerated due primarily to natural and anthropogenic processes. This loss makes an impact on the magnitude of flooding in the basin and threatens the ecosystems. In my research, I study three wetlands: the Amazon, Congo, and Logone wetlands. The three wetlands are different in size and location, but all are associated with rivers. These are representative of riparian tropical, swamp tropical and inland Saharan wetlands, respectively. First, interferometric coherence variations in JERS-1 (Japanese Earth Resources Satellite) L-band SAR (Synthetic Aperture Radar) data are analyzed at three central Amazon sites. Lake Balbina consists mostly of upland forests and inundated trunks of dead, leafless trees as opposed to Cabaliana and Solimões-Purús which are dominated by flooded forests. -

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. -

A Changing Lake in Response to Regional Rainfall Variability Lake Chad is a tropical lake with related wetlands. water level is too low, the Great Barrier prevents It has a northern and a southern basin of roughly water from flowing to the Northern Basin, the same sizes, which are separated by a sand causing that segment of the Lake to dry up. The barrier, referred to as the Great Barrier (see Lake is shared by Cameroon, Chad, Niger, and Figure 1). It is very shallow with a general depth Nigeria. Parts of the Central African Republic of less than four meters. The main rivers feeding are in its active hydrological basin and some of the Lake flow in its southern basin. When the the aquifers connected to the Lake are in Libya.
