Full textUnderstand the evolution and the recent variability of the climate in the arid and semi-arid regions is a necessity in order to anticipate what could be the consequences on the environments and on the societies of those regions, and thus define the strategic politics of sustainable development. To reach that goal, we have organised our research in three parts. The first part treats of the geographical plan through a detailed description of the physical environment and of the different systems of the ground occupation. This description put in evidence a fragile ecosystem under high pressure due to the activities which are employed here. The description summarizes also the middle climate frame by accentuating on the general mechanisms of the general circulation of West Africa which is part of the study zone. The analysis constitutes a recall of the dynamic average global conditions of the climatic tropical field which, in relation with local and regional factors, determines the average components of time in the study field and its margins. The second part concerns the analysis of the spatiotemporal variability on the period going from 1951 until 2005 by putting the accent more on the recorded rainfall than on other climatic parameters such as temperature, evaporation, relative humidity and insulation. But it underlines first the physical and methodological constraints which are compulsory for the statistic analysis of the parameters and justify also the models retained for the use of the database. The analysis of the recorded rainfall results show a high variability, but also a quasi stationarity from the end of the years 1970 and that until the middle of the 1980’s, and since an increase of the annual precipitation volumes on the totality of the study field. Compared to the evolution of other parameters (insulation, temperatures, evaporation and relative humidity), the middle of the 1980’s and the beginning of the years 1990’s appear like a period of trend “break up” justifying the questioning on the persistence or not of the dry trend of the Sahel climate in its totality. The third part starts by the analysis of the evolution of the vegetal production different time scale on the basis of a serie of synthesis images NDVI (Normalized Differential Vegetation Index) of NOAA-AVHRR on the period going from 1981 until 2005. The evaluation of the inter-annual and intra-annual evolution of the vegetal production in relation with the precipitations in the study field demonstrates a good correlation. On the other hand, the anthropic actions, within the framework of execution of the politics of planning disturb this close relation. This situation is put in evidence by the results obtained in the analysis of the cartography of the ground occupation changes between 1990 and 2002. The study conceived on the treatment of the images TM (Thematic Mapper) and ETM+ (Enhanced Thematic Mapper Plus) of Landsat in support of the statements of grounds; confirms the human action in the expansion from the bush savannah to arborous. After defining the characteristics, the follow up tool of the vegetation of the sensor SEVIRI of the satellite MSG is proposed. The corroboration of this new product is done on the basis of a comparative study with those of SPOT-VEGETATION and NOAA-AVHRR, frequently used in the scientific field. After a recall of the essential results of the research, the general conclusion insists on the exploration of solutions for water problems, important for a performing agriculture and a reduced mobility of the pastoral activity. And that passes through the multiplication of studies on the climatic variability, mostly on local scale. The general conclusion shows also the necessity of an approach of multi-sensors for the vegetation follow up. Finally, in order to bring more precisions for the comprehension of the thesis, you will find in the appendix elements concerning the characteristics of satellites as well as the sensors used and a study of cross validation on the techniques of spatial interpolation

Full textAmong the main topics that are currently agitating scientists, the unceasing biodiversity decline on a planetary scale raises a major problem which is sparking off as much concern as the global warming. Species disappearance as a result of ecosystem disturbances or from direct pressure on taxa is an undeniable reality. The Sahelo-saharan zone is part of the arid areas which have been badly affected by biological diversity erosion. Several species of antelopes are showing a precarious status or are even extinct. The Saharan cheetah, a potential predator of those antelopes, is now a too rare taxon, partly due to the collapse of its prey populations. Our researches are focused on the reintroduction of the Scimitar-horned oryx and the Mohor gazelle in the Senegalese Ferlo. In the first part the severe decline of the large Sahelo-Saharan fauna is presented, considering the status of a representative sample of six taxa : one bird, the red-necked ostrich (Struthio camelus camelus), and five mammals, the Northern hartebeest (Alcelaphus buselaphus buselaphus), the Addax (Addax nasomaculatus), the Dama gazelle (Gazella dama), the Scimitar-horned oryx (Oryx dammah) and the cheetah (Acinonyx jubatus). In the second part, we deal with the theoretical and practical aspects of species reintroduction and with small populations’ issues and the inbreeding related consequences. In the third part, we were interested in the first restoration outcomes of the habitat in which was carried out the reintroduction operation of the Scimitar-horned oryx and the Mohor gazelle, which have both disappeared in the natural environment. Habitat evolution monitoring has been studied by using a cartographic support coming from the interpretation of two satellite images taken at a two years interval. The use of the habitat by the reintroduced animals has been analysed for the two seasons characterizing the sahelian area and eventually the first data on the two antelopes population dynamics were examined in the light of the increasing size of both populations during the first three years. For a better management of next reintroduction operations, the monitoring of the habitat and the population dynamics of the reintroduced antelopes are recommended

Full textThis work synthesizes but supplements also our work on the problems of installation and development in Senegal north: hydro-agricultural and pastoral spaces. This area is characterized by the brittleness of its landscapes, but also by its important potential of development, therefore of development. To study such a space and the raised problems, we specified the variables to be collected and used suitable protocols. The study showed the dominating role of water in the configuration of the landscapes, in particular that of the pond in the installation of the campings, but also of the river through the choices of installation. In the wetlands, the changes relate to the extent of the degradation of the grounds, the weak rate of development and the production. In the dry lands, the strong concentration of the animals around drillings, the improvement of the capacity of the containers and of the performance of the means of transport, beside a space saturated by increasingly important animals, but also nibbled by the cultures, were observed. The land insecurity, the difficulty of access to the credit, the fall of the fertility of the grounds, etc threaten survival of the family small-scale farming. Individual and endogenous strategies are developed. The irregularity and the difficulties of access to water and the variability of the pastures oblige a greater pastoral mobility. Thus, we proposed solutions according to spaces characteristic and a better space distribution of the pressures

Full textThis thesis analyzes the practical implementation of knowledge in the context of access to medical care in Senegal and particularly in the area of "Ferlo”. It is a socio anthropological investigation registered under the scientific research study that aims to achieve an ethnography of public health problems in the "Ferlo" and more specifically the population of that area’s access to health institutions. Our research question is: how to understand and analyze the problems of health care accessibility in Senegal and more specifically in the area of "Ferlo"? It is through examples of regions such as Louga and Matam that our study of the conditions of people’s accessibility to health care is mostly based on. We analyzed the geographical, economical, and sociocultural factors related to the effectiveness of care that determines the health capital of these populations. It appears that the "Ferlo" is a deserted area as far as health infrastructures are concerned, which explains the high rate of morbidity and mortality among vulnerable populations including women and children. Apart from that health theme, we also interested in a comparison of living conditions and access to basic social services among urban and rural populations. It comes out from our research study that rural poverty is mainly due to low incomes, basic social services coverage problems, access to credit, water access etc. This study aims also at analyzing the material living conditions inequalities impact on populations’ health status and at identifying possible strategies implemented by families to alleviate the impact of a hostile environment on the health of their offspring. We also interested in the use of different treatment practices. These practices are discussed in the context of knowledge (traditional, popular, medical. . . ), relationships and social roles of which they are part and parcel. It is recognized that risk-sharing community systems, like the pre-financing for future use of health services, are competent to improve equal access to healthcare for rural populations. Our results record a single health insurance scheme in the "Ferlo”, which raises a real problem of management of health benefits costs. This study systematically reviews the methods and strategies developed by the population of the "Ferlo" to support health services costs and medicines. Solidarity is one such strategy. It exists as a self-help and financial support between family members and the community

Full textThe Sahel is characterized by a strong intra-seasonal variability of rainfall. This variability strongly affects ecosystems during the vegetation growth. The objective of this thesis is to characterize this variability at the local scale from the relationship between rainfall and vegetation dynamics, and to identify relevant indicators to better describe the variability in each season. This study is carried out in the Ferlo’s catchment, a basin located in northern Senegal. The first part is devoted to the characterization of the relationship between rainfall anomalies and growth of vegetation from remote sensing data TRMM3B42, RFE 2.0 SM-ECV (Soil Moisture) and MODIS LAI. Aiming that, the Ferlo basin is divided into 9 zones "homogeneous entity", in terms of vegetation cover class and soil type. For each one are analyzed the rain data from both databases, soil moisture and LAI over the period 2000-2010. In a second time, with a vegetation model adapted to the region forced by satellite rain fields, the LAI is simulated on several entities and is compared to the MODIS LAI, applying on the simulations the same methodologies as for observations. The results of this study show consistency between rainfall variations with both databases and soil moisture. The LAI variations are more strongly correlated with the soil moisture variations than with the rainfall. On the Ferlo, we observe that vegetation needs two weeks to respond to rainfall anomalies during the rainy season. At the season scale, the starting date of the rainy season does not affect the maximum LAI, unlike the duration and intensity of the dry spells. Entities located on sandy soil (ferruginous) have better sensitivity to rainfall fluctuations as those located on lithosoils. In addition, on entities located in the Southeast, the density of the shrub and tree vegetation induces a different phenological cycle than those of the herbaceous (lag of the maximum LAI). The model STEP, initialized with satellite rainfall data, reproduces after adjustment the vegetation growth stage in the entities where grassland dominates. The response of the simulated LAI to the rain anomalies is consistent with those observed, confirming the interpretation of observations. This study allowed to define the most relevant parameters that affect the dynamics of vegetation but also to highlight the capabilities of the model to describe the seasonal cycle of vegetation

To do this, we conducted a descriptive and cross-sectional study a mixed character with a quantitative and qualitative component 300 people for the quantitative component and 50 for the quality. It was apparent from this study that men were more likely than women with a sex ratio (male/female) 1.2. The average age was 36.13 ±14. Almost half of the sample was breeders and the proportion of persons educated or literate was relatively low (22%). The consumption of milk in liquid form of meat sheep, vegetables or leaves was very frequent. It was the active smoking with the consumption of alcohol commonly referred to as "boulfale" (eau de Cologne between 45 and 90 °) was 11% of the sample. Relation to hygiene practices, 76.3% had no toothbrush while 88.6% used the toothpick at least once per day. The prevalence of dental caries was over 90% and the needs of periodontal treatments were close to 50%. Compared to the General pathologies, 16% of the sample were hypertensive; almost 21 per cent had a declared digestive pathology. More than 70% of the sample (71.3%) were the traditional therapeutic use. The DMFT was associated with the digestive pathology and the types of care used on the age- and sex-adjusted. Periodontal indices were broadly higher in hypertensive patients. On the qualitative level, Ferlo Pulaar felt that dental disease could have a dual causality even if a vast majority originally was a natural

Full textIn a biophysical context characterized by important socioenvironmental changes, the main objective of this PhD is to understand how much agropastoral practices modulatein space and time the vulnerability and adaptability of agroecosystems and sahelians agropastoral societies. To reach this target, this question has been applied at macro-regional scale, relying on three micro-regional study areas: Ferlo (Senegal); Gourma (Mali) and Fakara (Niger) in which perceptions and representations of societies have been studied in a sample of villages and camps. The method developed in this PhD has two components: 1) remote sensing mapping based on satellite image processing, and 2) geo-textual analyses based on lexicometry from semi-structured interviews. The remote sensing mapping allowed to diagnose micro-regional and local scales on land cover change since the 70s until 2010. The diagnosis, based on a multiscale approach, shows intra and inter regional contrasts in the evolution of soil cover by vegetation that invite to nuance observations indicating a greening of Sahel. The articulation of remote sensing with field investigations helped to understand, first the evolution of plant resources, then to consider the variety of responses from the Sahel rural societies to the 70’s and 80’s climate crisis, and to the recent socio-economic changes experienced by sahelian countries. Through lexicometry, geo-textual analysis based on semi-structured interviews allowed to approach the livestock farmer’s perception about the vulnerability and resilience of natural resources. Thanks to the expressed perceptions, the adaptive practices were identified in their variety. It enabled to show the sociospatial reconfigurations in the trajectories of agricultural and pastoral activities that partly explain the contrasts within and between regions observed in Ferlo, Gourma and Fakara

Full textThe pastoral anthroposystem of Senegalese Ferlo evolves in an environment historically neglected by agricultural policies because of its characteristics particular biophysics, unfavorable to the agriculture and to the shape of development other than the extensive breeding. This primacy of the itinerant breeding is nowadays more and more disputed by the development of the farming in a context marked by the improvement of the conditions of the rainfall in West-African Sahel, soil depletion in the Groundnut Basin and the multiplication of agricultural development at the valley of the Senegal River. By combining the analysis of remote sensing imagery for mapping land cover changes by the vegetation cover, the study of flora and vegetation landscape and the exploitation of the investigations in villages and camps, this thesis attempts to define the geography of the vulnerability of rural populations and ecosystems which they use. So, pastoralists evolve with daily adaptation strategies in these circles inside Senegal marked by deep ecological instability and by the transformations at work in the Senegalese rural society. These socio-environmental changes contribute to the dynamics of plant landscapes and raise the question of ecosystem degradation
