Full textThis thesis describe thepossibilities of touristic development in the central middle-atlas. This area is caracterized by a place where a lot of people are used to go through. They move all around the imperial cities on the north, the big south, the littoral regions and the south-west. For the international tourism, first, it is a place to go. This area belongs to the big touristic trips. Anyway, the middle-atlas has always been one of the welcome sectors on the national tourism. This position has been tahen sinee the colonial period with the establishment of an efficient touristic politic. During the summer, the middle-atlas is dry and, most of the time, torrich for the flat country. It is like a real fresh oasis with green areas and beautiful cedar-trees all over besides, the imperial cities are often very close and, some stations like immouzzer and fes have got their life connected together. The national interest for the middle-atlas is increasing by the "informel prostitution tourism". Since the independance and the progressive starting of the european community, the tourism is on important recession to achieve, in certain cases, a residual tourism. Alore and sometimes with a lot of difficulties a social tourism is still there. This tourism is made by the authorities or social organisms. Nowadays, a creation of infrastructure is beginning, which is organized by

Full textThe climatic orginality of the central atlantic facade of Morocco is pointed out. This originality is explained by the proximity of ocean with its specific thermodynamic property, well detected by the remote sensing tool. The coupling of ocean and climate is demonstrated ; the spatial extension and the diveraity of aceanic climatic domain are precised. This region is distinguished from the reat of the atlantic facade by colder marine waters. The coastal upwelling results from the permanence of north and north-east winds. The themography has permitted to understand the thermal superficial structure of the sea at a scale and with a precision previously nver resched. This structure is variable batween the warm and relatively homogeneous north and the colder and very heterogeneous south. These thermal oppositions are at the origin of the oceanic climate diversity in the region. The oceanic influence varies along different coastal sectors according to the extent of thermal marine phenomenon. The southern parts especially have an important summer coolness. The ground surface temperature are wore moderate and the daily and seasonalthermal amplitude are well reduced to the south, in relation with the upwelling. The impact of the sea is also illustrated by the high frequency of cloudy skies above coasts during the warn season, with a geographical contrastingrrepartition. .

Full textThe objective of this research in hydroclimatology is to define the general flow characteristics conditions of the oued Grou, as a knowledge of water resources, in a region which is marked by a grave dryness. Tributary river of Bou-Regreg, the grou is representative of the characters of the border of south and south-est of the plateau central. The channel seems enough regular although it crosses hilly regions with watertight substratum, characterised by a great discontinuity of vegetal cover. The type of climate is semi-barren mediterranean. The essential characters are represented on one hand by variability which is linked to a great year irregularity and at the existence of sequences of dry and wet years, and, on the other hand, by a great contrast of seasons (alternance of a wet, clement season and a warm, dry season). The river flow follows the distribution of precipitations with two distinct seasons, a short high flow and a long period of low flow. The study of average shows, in terms of frequencies, how intervenes the prevalent list of weather conditions and lithology in the flows. This list is confirmed with a statistical study of extreme flows (rising and lowest water levels). The knowledge flows is realised at the catchments areas controlled by hydrometric stations in the water balances. The water balance use the models of space quantification of rain, temperature and the determination of characteristics flows by analysing hydrological phases. This approach shows the dominating effects of permeable formations and scarceness of water tables, favours the overland flow and bounds the alimentation during low flow. This research shows the necessity to increase the knowledge of water resources and how the present indufficient system of measure must be improved

Full textThe commercial cultivation of fruiterer rosaceae in morocco, especially in the middle atlas and its surrounding areas is a recent introduction. The first fruit plantations in this area date back to the time of the protectorate. Since then, the area under production has grown considerably. Today, the middle atlas is throught to be on of the principal producers of temperate fruits in morocco. Most of the orchareds are to be found around the perimeters of imouzzer kandar, azrou, ait oumghar ans on the amekla plateau. Because of its geographical qualities, this areas measures nowdays 5432 ha grown apples, pears, cherries, peche-nectarines and plumes. The development of this productions is due to local as well as outside factors. Among these, the market, the population increase and the urban capitals have played an important role in this. The introduction of a modern cultivation in a traditionnal rural area has had important economic, social and mental consequences. The impact of this transformation have changed among others, the standard of living of the "fellahs" converted to this speculation and have caused a degeneration of traditionnel methids. But this to this specilation and have caused a degeneration of traditionnel methods. But this agricultural mutation has also brought with it several new problems to resolve. Some of the most importants are the overexploitation of the local ressources and the worsening of the social unbalance of a regional scale

Full textThe middle part of the Souss plain, on both sides the eponymic main stream, is characterized by the existence of large evident sedimentary structures in the global morphology which are the large atlasic and anti-atlasic alluvial fans, the alluvial terraces and fields of dunes which reinstall in occasion of long drought. Except these sedimentary structures, the detection of a lakeside system remains rather difficult. The indicators of the existence of palaeolakes or palaeoplayas limit themselves to the planar aspect of certain parts of the Souss plain, to the conservation or not of the Argan forest, but especially in the existence of calcareous benches at the base the oued's left bank. The Souss lain was commanded by a tectonic activity bounded to the recurrent faulting of inherited faults, as weil in the basin as in the plain, and in a subsidence which probably continues. Two generations at least of Plio-Villafranchian palaeolakes were established within the depression. Their summit was covered by the deposits of terraces of the oued Souss, by the deposits of the High atlasic's and the Anti-atlasic's alluvial fans distal deposits and by dune fields. The wet limate in regular precipitations which reigned over the Souss plain during the Plio-Villafranchian left place to a succession of paleoclimates responsible of major notches and construction of new generations of alluvial fans on High-atlsic's and Anti-atlasic's piedmonts; the Anti-atlasic's piedmonts were drier and have allowed the installation of dunes. More wet and more dry phases altemate undoubtless during aIl the Quaternary. The unique phases identified here are situated within the "Tardi-Soltanian" and the Upper Holocene. The last phase of increasing aridity settled down since the Upper Holocene until the Current, and was interrupted by wetter episodes. The anthropological action has stressed many aridification aspects: prolonged oued drying, gulliying, fall of phreatic water-table. The Souss epression which saw lakes developing over more than 1000 km2 during PlioVillafranchian and which was yesterday even the larder of the Saâdians (sugar cane culture) offers today sorne land drought aspects

Full textThe hydro-archeological study of the Tassaout basin, situated in the western atlas region of marocco, has revealed a large number of remains of the ancient irrigation network which ran through the region. This collection of ancient canalizations (seguias), dating from the XII up to the XIX century, have been realized under powerful regimes which had the capability of bringing to fruition long term projects such as those discovered. The existence of these regimes (state, collective, regional or religious) have left their mark on the agrarian landscape of the basin in creating different models of hydraulic earthworks. The human activities which have held sway over the different eras during the evolution of the basin, is traced within the structure of these ancient edifices. Their diversity, marked in the landscape reflects the changes in climat as well as in politic, economic and social context and provides a model of the history of this region

Full textThe basin-slope drained by the oued Neckor and its affluents is part of the Mediterranean slope of the Central Rif (Morocco). It is a geographic space experiencing an intense morphological change. This vigorous and varied erosive crisis brings about an upheaval in the hydrological structure shaped at the end of the quaternary. The serious damage to the basin-slope gives birth to a new hydrological structure characterised by the rapid expansion of bare areas (torrential areas) and by a heavily-torrential regime. This worrying situation requires the views of a geographer. His views, governed by a deep observation of the area and an adequate reflexion upon the subject, offer a diagnosis closest to reality. The climate, characterized by a long dry season with little rain, cannot explain alone this crisis. The same for man's part which is but small fraction in the damaging process. Actually, man has only deteriored necessarily his fragile initial environment. This fragility is then the result of the conjunction of a series of geological conditions working actively and efficiently on the destruction process of the basin-slope

Full textIn the High Central Atlas, precipitations below 1500 m are higher on the occidental side, conversely of the oriental side. Results, through the pressure gradient calculation, show that the orographic rains supply, is the main cause of the bad pluviometrical distribution. This leads to say that the high central atlas, because of its altitude, constitutes a sufficient barrier to develop a sheltered climat, the own characteristics of which, are to bring up orographic precipitations. As to the tadla plain, consequences affect temperatures reaching high maximums, especially during the vegetative period. These temperatures squared with significent evaporations accentuating the need of water. This has led us to study evapotranspiration. The first idea was to apply the etp estimation formulas to the direct measurements, available from Beni Mellal

Full textThe bassin of the lebene wadi is a heterogeneous entity integrating the southern rif's and the pre-rif's unity. Its structure is the result of carrying, resting on the original unities. At the end of the miocene, all of it was put through active tectonics. The lithostructural contrast and the differential erosion explain the organization of the morphological system in which the dense hydrographic network has resulted in the present from of the relief. Hydrographic network has resulted in the present form of the relief. Six levels belonging successively to ancient. Middle and recent quaternary periods trace the basin's evolution. The karstic froms and the slopes which bear marks of the col climate have much developed since. Most of the elements of the relief bear thick detrial formations which constitute at present a stock of mibilizable materials. The deposits that have followed the latest rharbian accumulations reflect the chemical, hydraulic, mechanical and anthropical erosive activity. The hydraulics of the lebene express the brutal character and the exterme variations depending directly on the precipitations and governed by its morphometricla and morphological characteristics. The average hydrological outcome is almost stable. The outflows of exceptionnally dry or humid years show exterme deviations regarding the module. The wintertime floods are brutal and the summertime low water is frequent and durable. Al of this has repercussions on the natural environment and the human society. The hydrochemics of the water show a strong concentration of ions of the sodium-chlorine

The evolution of thess formations could be summarized in the differenciation more or less pushed of the calcrete profile and the general tenduary to fluvisols. The microscopic fabric of calcarous crusts shows the role of the carbonates as an alteration agent by epigenisis. The study of fluviatile terraces underlines the great analogy of the hydrodynamic conditions of alluvial setting and the close relationship between the degree of the evolution of weathring profile and the age of alluvial formations

Below one thousand five hundred meters, precipitations are higher on the leeward side. However, it is just the opposite on the windward sid e. The results point to a greater heterogeneity in the distribution of precipitations on sides facing westerly winds. One of the explanation lies in the fact that the very height of the high atlas central range acts as a natural barrier helping to develop a sheltered climate. One of the distinctive characteristics of such a climate is precisely to bring u p orographical precipitations

Full textThe High Atlas chain of Morocco represents the northwest part of the epicratonic – Peri-Tethys African domain. It recorded break-up phenomena (stretching of crust) of Lower Liassic carbonate platforms and the setting of deposits in Atlasic basins. This work is based on a cartographic, sedimentological and biostratigraphic study at photosatellite and outcrop scales along the Tizi n’Firest structure, to try to understand the dynamics of the depositional settings of these sediments and their interaction with the factors controlling sedimentation. The regional analysis of satellite photographs and deposit geometries at large and small scales showed that the Tizi n’Firest fault consists of segments of normal faults and of transfer faults of variable lengths and orientations (NE-SW, ENE-WSW and E-W). These faults inherited from the Hercynian orogenesis drove the Liassic sedimentation in small basins with oblique extension dynamics. Two large sedimentary features, Amellago to the west and Rich to the east. Liassic deposits show a general deepening evolution, with shoreface to offshore facies at their base and bathyal to abyssal facies at their summit. Through time, facies are distributed according to two depositional environments: ante- to syn-Sinemurian ramp and Pliensbachian platform with slope. Gravity deposits are abundant and display various organizations depending on the influence of transport distance, sedimentary load and depth. The presence of Amellago-Rich basins in a geodynamic context displaying an oblique rifting –based dynamics led to a heterogeneous functioning and filling of blocks and a temporal shift in the periods of subsidence

Full textTourism is inserted in the high montains of central maroccan high atlas as means of local development. The aim was to struggle against the phenomenon of rural exodus and to create on the spot a motor for enrichment able to give importance to the natural elements considered as hostile by the mountain dwellers. The aim of this research work was to study this development policy and to try and find out if the state's will has succeeded. By analysing the tourist flow and the various economic repercussions on the region, it appears that tourism does not totaly assume its development role and this is due to several factors. In fact the revival of interest for the montain can be explained by the changes in the tastes and motivations of international tourists who are looking for paradise on earth in every region in the world sheltered from the harmful effects of urbanization and industry. The high mountain in central high atlas has become an object of admiration and a place of refuge for international tourists. This has imposed a type of tourism both diffused and respectful of the environment, which does not come up to what population' expects ; the people demand the tarring of the tracks and the introduction of big installations and developments. The state has tried to answer both these expectations and the tourists' but it has succeeded rather for the latter than for the former. Thus the global policy of local development is confronted to a kind of imbalance which advantages the exogeneous rather than endogeneous and local factors, even if apparently seems harmonious. The first part of this study aims at stressing this imbalance whereas the second part shows the limits of this insertion of tourism in a more concrete way

Full textThe problem of erosion in Tafrant mid-Ouergha is a crucial one. This phenomenon is everyday manifestations which are widespread throughout the region because of favorable conditions. Effectively, the structure, which is characterized by multiple thrusting water sheets such as thase of Ketama, Tangier, Loukos, and ouezzane, gives a young and vigorous relief consisting of a number of ridges ( ridges of Benimesguilda, Tafrant-Tabouda, and ridges of Beni Oueriagel). The lithology dominated by series of marl-particulary in the sectors of the pre-rifaine zone, and the mid-parts of ridges-remains favorable for the erosion's manifestations. The climatic factor is also very important since it has disastrous effects on the soils. The heavy rain, concentrated in few days of the year causes tremendous damages. In addition to what have been mentioned above, there is an anthropic action which contributes to the break-down of the natural equilibrium in this region ? Thus the current erosion's forms are obuious in most slopes. Among these forms, we have gullies, slides and muddy flows. The various anti-erosive attempts are limited, and sometimes they miss-fit the region's conditions

Full textThe commune, which is a recent administrative creation, is instituted in order to destroy the ancient tribal organization. The communal transplantation is thus to be noticed in a double social and historical process : on the one hand, a process of unification of a way of live, a new kind of the individual, indeed the appearance of the citizen in the mpdern conception of the word. On the other hand, a process of "distructure"-"restructure" as a tool to achieve the policy of development decided by the state. However, as a territorial unity and an agent of local development, the commune doesn't thoroughly neglect ancestral ethnic borders and even pleases the local traditional group of notables. It thus emphasizes a political will of continuity and makes one wonder about the real effect of decentralization. To clarify these continuities or and these ruptures, these evolutions and the appearance of a new citizen in a rural world which "is going out" of its tribal system, the example of el hajeb area is particularly significant by its central geographic situation in the heart of morocco, the existence of twomain tribal confederations (the beni m'tirs and the guerrouanes), the juxtaposition of distinct soils (jbel, dir, azaghar), etc. .

Full textThe study in this thesis is concerned principally with the domain of agricultural geography, especialy in the mountain regions of the north of morocco. It consists of an analysis of forms of organisation of agricultural areas in the rif region and the problems that are caused by the carious forms of organisation, and their impact on the society in the central southern rif area. In order to study these of organisation of agricultural areas we have adopted an plan which comprises three separate but integral parts : the first in concerned with the natural milieu, its elements and its main characteristics, as well as its impact on its agricultural organisation and the population and housing distribution. The second part deals with the basis of organisation in this region. It expose firstly the population growth and the reasons for it, as well as the phenomenon of migration and housing in the region. It also discusses the agricultural structures and forms of rural organisation in the area, emphasizing the imbalance between population growth and small-holdings as well as the techniques of soil utilisation. The third part is reserved to study of menagement in the area and the changement of the society, also the methods put into practice

Full textThe piedmont of the ouarzazate basin is the central unity of a neogen basins series (souss the west and irrachidia to the north-east) laying out the central high atlas south slope which corresponds to the main element of the alpine chain. The geomorphologic study of this piedmont is included in a series of studies concerning neighbouring zones. We have made several field works to draw a geomorphologic map which was the main too this study. It shows disparities between the east and west of the basin in relation to tectonic and climatic factors. The continuation of the atlasic tectonic evolution until recent quaternary had different traduction in each quaternary geomorphologic evolution stage, but the main was important detritic discharges. Accumulation has defined the built of very large stepped glacis. They are mostly covered by coarse material consolidated in real encrusted flag, somewhere topped by a calcrete. These sedimentologic characteristics and the disposition of the deposits shows that tectonic is the main factor, but not the only, in the geomorphologic evolution of the piedmont aridity is the characteristic common at the whole ouarzazate basin piedmont. The water deficit is continuous and water ressources are limited. This water rarity and the exiguity of agricultural areas induce the specific social organization and exploitation systems of this region. The drainage pattern has been used as structural indicator to identify the deep structure of the basin.

Full textThe institution of governor, in its modern status, created in 1956, has survived to so many contingencies in the modern Moroccan history: instability in the 1970s, the setting of a new era of administrative laws stabilizing the governing system, and the recognition of a limited autonomy to territorial collectivities through decentralization process in order to mitigate the centralization inconvenients by adopting “administrative deconcentration”. The objective of this thesis is to study the elements of continuity characterizing the action of governors. This contribution is an attempt to identify them in regard to their status and competencies. The institution of Governor in Morocco plays a central role in the local administration of the country, the study of its genesis, its legal status, rights, obligations, responsibilities, and functions, both traditional and modern has an accurate interest. This thesis is intended as a contribution to the actual debate on institutional reform in Morocco

Full textThe living conditions of the population in the Anti-Atlas Mountains are not ideal for agriculture: rains are very irregular and insufficient; the soil is skeletal and stony, as it develops from an old geological substratum and on steep slopes. To make up for those hostile conditions, for centuries and perhaps for millennia, the mountain society of the Moroccan Anti-Atlas has endeavoured to manage the slopes so as to preserve arable land and especially to capture rainfall runoff, so as to imbibe the land with it. Nowadays, those structures are sometimes fossilized and threatened with disrepair and destruction now that agricultural activities have come to an end. This situation is striking in all the Anti-Atlas areas I have travelled through. The work and the skills of local farmers are therefore in danger of being lost. It is essential to study those artifacts while they are still partly functional, as they can still enrich the cultural potential of this southern mountainous area, already rich of its many landscapes and architectural vestiges

Full textThe work that we present in our research is a lexicographic end-product, that is, a presentation of the lexis of verbs of the Berber variety spoken in central morocco. The major part of our research is devoted to an inventary of 1241 non-derived verbs. These verbal unities, as they are accumulated so as to form a dictionary of Berber verbs, are classified according to the semitists' order, that is the root. Once the collection of the verbal unities has been achieved, the presentation of the different uses is imposed. To achieve that, we have followed a classification based on syntactical criteria knowing the transitivity and non-transitivity of the verb. This verbal formula has helped us deduce the different meanings of each unity. Our dictionary is accompa-nied with one part which we have tried to present each unity in one of the following verbal structure : category a gathering the intransive verbs, category b constitued of compulksary or optional direct transitive verbs, category c and category d to which belong the direct and indirect transitive verbs. Finally we have summed up all the verbal unities in tables where their transitive or intransitive use showed up

Full textT. A is the native speach of the tamazight population of azrou, wich is the chief town his consonantic system is constitutes from simpl and emphatic and tight consonants. In phonologic level, the emphatic articulation is a property of the segments t, d, s, z, r and of their tight correspondents. In phonetic level, all segments, except for q, and for the vowel a , are emphatic if the underlying representation contains an emphatic segment. The tight consonants are not long everytime, because the tight articulation isn't manifested only by the duration. The vowel system contains the fundamental vowels i,u,a wich are very sensible to the coarticulation. Their number is enriching by the phonetic element (a) wich is solicited in other to disjoint consonantic groupes. The semiconsonants know many treatments dependently of the fact that they are tight or not and initial or intervowl or final. The rules of phonologic syllabification allow any consonant to be the syllabic peack. The phonetic syllabification takes only vowels as syllabic peack
