INTRODUCTION17 Problem of land use and water supply in urbanarea: the case of the city of Touba, Senegal.Papa Demba CamaraUniversity Paris 8 – Institut d’Etudes Européennes2, rue de la liberté 93526 Saint Denis – France3, rue Auguste Poullain Apt 2208 - 93200 Saint Denis - France5 Claremont Road UKpape27@hotmail.frAbstractThis study focuses on the relation between land use and water supply. It resultsfrom direct observations coupled by semi-structured interviews with localactors. In urban areas of Senegal, water is drawn from two sources, from thedrinking water network and from traditional wells. Our study focuses on thecity of Touba, a city which is singled out by its recent character (new city) andby her religious inclination (religious city). The naturals conditions areunfavorable: low rainfall, depth of the groundwater with wells brought up ratesin salt and fluorine. Two types of land use have been identified in the city: atraditional occupation and modern occupation. They have real consequenceson water supply. A city of 700000 inhabitants, Touba hosts two millionspilgrims every year. Water quality and the quantity have always been the mainproblem for the people and pilgrims. The first consequence of water lack isunhealthy. Water-borne diseases caused by pathogen agents appear in this cityso endemic.Keywordslack, pathogens, quality, water borne disease, water supply, wellThe galloping demography of black Africa countries and the exponential urbanization of somecities of the continent so disparaged just after independence (1960) that it does not seem to beready to stop. At the beginning of the 3 rd millennium, a new urban mapping is taking shape: wetalk about urban revolution. Next to the ancient city, some new cities came into existence, thesame case with Touba Senegal, very recent city. The cities of second generation contributecertainly to ease congestion in capitals and to readjust the urban mapping. But like the oldcities the new cities also have certain problems such as poor planning systems, anarchic landuse, deficient water supply, no sewerage systems etc.This essay is about the relationship between the systems of drinking water and land ownershipin urban areas. This is not an exhaustive essay because it needs more research for the problemsto be identified and because of the time constraints it is difficult to do the thorough analysis.The study carries reconciliation, generally speaking, on the concept of sustainabledevelopment between fast economic growth and the environment. But in this particularcontext, we are talking about the relationship between population growth in Africa and itsenvironment. Indeed, in countries with low economic development, demographic weightdrastic affect on the environment.This study in the first part describes the city of Touba, what makes its prominent, is the waythe space is occupied and used. Touba the religious city suffers from the problem of limitedwater supply. Touba is a holy city, but because of contaminated water it seems literally“mucked up”. This study will try to cover this subject in the second part, and finally, the lastpart will focus on inherent health problems associated with the water in Touba.MATERIEL AND METHODSThis work examines the relations between land usage and water supply in urban areas. Itresults from direct observations coupled by semi-structured interviews with local authorities,people and doctors. We visited some drillings, health centres and interviews some families.Basically our methodology can be broken down into three steps:Documentary research:It allowed the collection of secondary data and guided us to visit the chosen places andinterview the most likely affected families.Semi-structured interviewsOur study is based on a qualitative approach purpose of which is get from the locals first handinformation. Thus we discovered that it is in the relations of one-to-one debate that the localsdevote themselves more and we benefited from their personal experience.ObservationOur presence in the field has enabled us to witness what the locals face to get basic supply ofwater. Easy access to water is not an easy mean in Touba. The locals travel about 20 miles toget access to drinking water which might not be clean water.Keep in mine that this study was made easier by the various people whom we met during ourfield visit and was able to provide us with accurate information we need for this research. Welike to take this opportunity to thanks them for all their support and wish them all the best.TOUBA: BETWEEN TRADITION AND MODERNITYLocated around 200 km east of Dakar, Touba is a Muslim holy city of the mourid brotherhood.The city of Touba was founded in 1887 by Sheikh Ahmadou Bamba. In just few years ofurbanization, Touba has become the second biggest city in Senegal after the capital Dakar.With an area of over 20,000 hectares, its urbanization was mainly facilitated by a paternalisticland system, based on donation or a free attribution of plots, but also marked by speculation.The development of the city is link to the great pilgrimage which celebrates every year thedeparture into exile of the founder of the mourid brotherhood, Sheikh Ahmadou Bamba.
