Gurgand, Marc. "Education et efficacite de la production agricole : estimations en coupe transversale et en pseudo-panel sur des donnees ivoiriennes et taiwanaises." Paris, EHESS, 1997. http://www.theses.fr/1997EHES0009.
Full textThe effect of education on technical and allocative efficiency in farm production is measured for cote d'ivoire and taiwan. As productivity is measured directly, this partly overcomes difficulties encountered in interpreting mincerian function estimates (due to labor market iperfections). Based on profit function estimates (with adjustement to take into account rural household model non-recursive. Ness), contrasted results are obtained: there is no return to education in ivoirian agriculture while the return is positive in taiwan. This can be interpreted with reference to th. Schultz's statement that the return to education is high in unstable or modernizing environments, but can be negligable otherwise. An original model allows explicit testing of this theory: assuming individual behaviour is not optimal and allocative mistakes happen as a result of unstable economic environment, it is shown that farm profit can be stated as optimal profit minus some index of agricultural price variation. Estimation over 17 repeated cross-sections (pseudo-panel) in taiwan illustrates that return to education is higher, the more unsteady prices are. The same holds for climatic instability. However, wage variation does not affect farm vs. Off-farm work allocation. Recent pseudo-panel data methods are implemented, including identification of fixed-effects models and microsimulation

Full textThe previous decade (1980-1989) showed quite a noticeable stop to any economic development throughout all the subsaharian countries. Though increasing growth rates were about to be at their uppermost in the sixties and in the seventies in some of those countries, the eighties were characterized by a drop in the rates. This situation led to a tremendous fall in agricultural producing and this in agricultural export income : such was the case in the ivory coast where cacao and coffee productions are the main resources which reached their lowest level. In fact, all the marketing system in the ivory coast is under a monopoly of state. The state has a strong hand upon commercial transactions inland and outland. It means for producers a high levy on agricultural prices and thus low prices fixed by the state. All those reasons brought us to an analysis of development processes in developping countries through the example of the severe economic flop in ivory coast. We shall aim at connecting the economic development with variables such as agriculture, property rights structures and marketing of produce through free market patterns from february 1992 to june 1992. Each topic of our investigations was gathered on questionnaires in order to cover our scope. Thus, our representative producers answered questions concerning marketing of agricultural produce, contract systems between landowners and plantation workers, property rights structures and finally agricultural financing systems. The first part shows the problem of development and its link with ivorian agricultural policy. In the second part of our study, we end our investigations dealing with the inefficiency of a strong bureaucracy set up by the caistab in the marketing of the products

Full textPour tester l’efficacité du traitement antiparasitaire courant en pisciculture, des élevages de Chrysichthys nigrodigitatus ont été réalisés dans le sud de la Côte d’ivoire dans des milieux écologiques différents. Pendant l’essai, l’Ovaldine® a été associé au Slice® (OS) ; le Parasiticide-S® au Pycèze® (PP) et la chaux a été utilisée seule (CH). Ces produits ont été utilisés à Jacqueville dans trois étangs différents. Quatre autres élevages ont été conduits à Layo, de Mopoyem et d’Anyama parallèlement à celui de Jacqueville où les étangs n’ont pas été traités. Au terme de cette étude, les poissons traités présentent en termes de performances zootechniques et d’indices épidémiologiques une différence significative comparativement aux poissons issus d’élevage non traités. En revanche aucune différence n’a été constatée chez les poissons non traités. Malgré ces différences de croissance de poissons imputables aux antiparasitaires, l’utilisation des produits chimiques en élevage pose non seulement des problèmes écologiques mais aussi, constitue un danger pour le pisciculteur
To test the effectiveness of current pest control treatment in fish farming, Chrysichthys nigrodigitatus have been made in the south of Ivory Coast in different environments. During the testing, Ovaldine® was associated with Slice ® (OS), the parasiticide-S® to Pyceze® (PP) and lime was used alone (CH). These products have been used to Jacqueville in three different ponds. Four other farms were taken to Layo of Anyama Mopoyem and parallel to that of Jacqueville where ponds have not been addressed. At the end of this study, the fish are treated in terms performance zootechnical and epidemiological evidence have a significant difference compared to farmed fish from untreated. Despite these differences in growth of fish due to pesticides, the use of chemicals in farming poses not only environmental problems but also constitutes a danger to the fish farmer

Full textThe purpose of this work is to study the expansion of food crops for urban markets in Côte d'Ivoire. It's a new phenomenon by the scale, which results from the spectacular urban growth country for a few decades. In the first part, are studied the general conditions of emergence of food crops for scale: urban markets, potentialities of the countryside, evolution of food crops since colonization. The second part shows the development of food crops for feeding cities in the south of the country, where cash crops (issued from coffee and cocoa plantations) overshadow all others. The third part is about northern areas where export crops are not extended, and where food crops play an important part in various agricultures. In the fourth part, the study of transport, trade and its actors underlines the importance and complexity of relations between farmers and traders. The conclusion lays stress on the dynamism of peasantry, the adaptability of land systems, and the numerous consequences (for society and space) which are resulting from the development of food crops for sites in Cote d’Ivoire

Full textThis thesis tries to understand and explain the very cause of the agricultural deforests done in the classified forest of Irobo-Méné. It analysis the fundaments of the relations of the colonial and postcolonial States, as well as the people from the deforest area, with the land and its resources. The founding is that, in their coexistence, the pattern of local organization towards the use of the lands is submitted to a profound evolution, under the influence of the State's model of space distribution, at its turn accompanied by the expansion of plantation agriculture and monetary transformation of economy. At the same, the social practices associated with the State's control are dominated as well by a radical transformation. The situation determines a strong individualization among citizens, along with the modification of land's usage. This internal dynamics of the rural communities has been reinforced when the State had liberalized the exploitation of the rural space. The phenomenon determined the apparition of social, economic and political strategies, all in confrontation towards the ownership of the lands. Consequently, this relation with the lands, dominated by money, has been prolonged into the classified forest

Full textIn the classified forest of Monogaga, a national natural patrimony of Côte d'Ivoire, the farming practices exert a ceaseless pressure on forest cover. After a period of groping and conflict with the local people (Wanne and Bakwe) who were maintened in the forest after its classification, the official manager, Sodefor, decided to yield a part of the protected area to local human activities by creating agricultural enclaves. To answer the interrogations concerning the transformation of forest cover in these enclaves and in other parts of the Forest, this study had two complementary objectives :1)to describe the current state of the forest cover in the classified forets, which is poorly known on a phytosociological point of view and 2)to compare the respective impacts of the villager's practices and action of Sodefor on the vegetation community composition diversity and endemism level. Our methodology associated an anthropological approach, which investigated the patial organisation of the activities and the representations of the two principal forest actors and a botanical approach based on inventories from plots of 500 m2, observations of the vegetation cover and physiogonomy. .

Full textThe objective of this thesis was to justify the performance of the ivorian agricultural industry (ag-industry) through out its market structure. The thesis used traditional and modern theory of industrial organization and linked them to ag-industry. The thesis shows that the ivorian ag-industry faces a quite paradoxal situation as far as economic efficiency is concerned this is due to the high level of protection and concentration. In other words, the agricultural and food sector did not benefit from profits earned from the existing market structure. Government intervention in all ag-industrial activities has created non-rational practices from an economic standpoint. This situation is due in part to community constraints which, in africa, are ranked number one priority in firm management

Full textThe northern region of Ivory Coast, which has a varied climate of the sudanese type and a rural population density that is on the average small (with the exception of the surroundings of Korhogo), has, since 1960, seen the creation in the low-lying areas of 269 dams for the use of animal raising and 19 others for the irrigation of rice fields and for truck gardening purposes. The customary form of farming of the Senoufos of northern Ivory Coast, has been radically transformed with the use of hydro agricultural dams for the development of irrigated rice growing and agricultural pastoral dams for truck gardening. The presence of permanent waters has generally been appreciated in villages where people have seen their living conditions been improved. Facing the multi-purpose of these dams leading to a raise in the contacts between human and water, the risk to see some water diseases appear or reappear is getting more and more serious, especially for schistosomiasis. Surveys conducted on the inhabitants of 10 villages have allowed to realize that the risks of schistosomiasis development linbed to the new water conditions were still relatively weak in the North of Ivory Coast but vigilance was still necessary

Full textThe post-colonial Ivory Coast tried to endow with a domanial and landed regime through the non-promulgated law of march 20, 1963 to promote the develoment. The reaction of the peasant communities against this produced a non promulgation of the text. This resulted an empty judicial state full of the principle "the land belongs to whom who appreciates it on the condition of observing the law rules of the late felix houphouet boigny. The polysemic, the polymorphy and the polyvalent characters of this adage secured the land actors. It showed itself performed : another way, it was social-logically and judicially effective during decenny sixty-ten period. But from the year of eighty, it was the origin of the insecurity, contradictory stakes, and to remedy this the trustee w as the alternative of security. But in the measure where this trustee operated out of the legal frame, it did not respon d to the actual stakes of security, from there the necessity to promote a new mixed land-right of the 21st century; "the intermediation" to get out the dead-end where the country was swallowed-up

Full textThe upstream watershed of White Bandama, north of Ivory Coast, is located on a fissured hard-rock, composed of granites and schists, and is a perennial aquifer for populations’ water supply. The upstream watershed of White Bandama, northern Ivory Coast, is located on a hard-rock aquifer which geometry and potential as an hydrogeological reserve is not yet well characterized. Insecurity of rural populations is partly due to lack of drinking water as well as still inadequate number of water supply points. A significant number of failures was observed when performing wells and boreholes for groundwater, one of the causes is a weak scientific knowledge on the environment.This study is to improve knowledge on the hydrodynamic behavior of the hard rock reservoir (geometry of aquifers, hydrodynamic parameters, recharge, availability of the resource) in order to drill perennial boreholes.The multidisciplinary methodological approach integrates hydrogeophysics, hydrogeology, geology, chemistry methods. It is to develop new techniques and appropriate exploration tools to refine the characterization of fissured hard-rock to better constrain the operation of sites, especially in terms of stability of pomped yield.To study the hard-rock aquifer of upstream watershed of White Bandama, we coupled electromagnetic measurements to lithological data to refine the geometry of the aquifer and to better constrain the choice for future drilling locations. This study presents a new hydrogeophysical approach using the multifrequency electromagnetic device PROMIS® to improve knowledge of resources on hard-rock aquifer, at the local or regional level.Our geophysical data are interpreted with multi-layer models consistent with the discontinuities observed in lithology logs and the geology of the site. This method is effecient to improve the characterization of the hard-rock aquifer, and the results showed good agreement between the soundings (1D), the resistivity cross-section (2D), drillings and geological structures.Results allow to precise the local thicknesses of the 3 main units of our study area down to 50 m, being from top to down, saprolite, a fissured-rock zone and the rock substratum. The fissured-rock zone constitutes the main aquifer unit under pressure, interesting target for productive water wells. Its thickness ranges from 15 to 30 m. A detailed knowledge of the local aquifer geometry constitutes the first and crucial step before going further into a complete hydrogeological study

Full textIn Sub-Saharan Africa, population growth and climatic variability generate significant population movements in direction of protected areas. The installation on the periphery or inside the protected areas, exposes the human populations and the animals that they raise to the bite of insect-vectors able to transmitting pathogens (yellow fever, leishmaniasis, trypanosomosis etc.). This is the case of tsetse flies, vectors of Human African Trypanosomiasis (HAT or sleeping sickness) and African Animal Trypanosomosis (AAT). In Côte d’Ivoire, population increased from 2.6 million (8 people/km2) in 1950 to 23,1 million in 2015 (71,6 people/km2). The process of deforestation for agriculture development (coffee, cocoa, rubber tree and cashew plantations for example) have led to a land saturation, which are oriented agricultural populations towards protected areas. This increasing of anthropic impacts in and around protected areas exposes human and animal populations to tsetse fly bite and trypanosome risk. The objective of this study is to report the process of exploitation of territories situated in margins and inside two protected areas and to evaluate trypanosome risk. More precisely, the first step is to characterize settlement dynamics (creation, extension and multiplication of stands, increase in human population densities) and changes in the rural area (areas cultivated and types of crops) outskirts of the Taï National Park (forest) and the Comoé National Park (savannah). Activities carried out by the surrounding riparian populations and within these protected areas is also studied (gathering, hunting, fishing, grazing, gold panning, etc.). In the same time, in order to assess the risk, entomological surveys (species diversity, density and infection of tsetse flies), medical and veterinary surveys (seroprevalence, prevalence of HAT and AAT) were conducted. This "One Health" approach provides a better understanding of how populations exploit marginal and protected areas and measure trypanosome risk exposure. In view of the demographic projections and future land issues associated, this theme appears essential for the elimination of human and animal trypanosomiasis. This study helps to reach the goal of elimination of THA in Côte d'Ivoire by 2020

Full textPostcultural secondary successions have been investigated along a chronosequence of fallows embedded into a semi-deciduous tropical forest matrix (Ivory Coast). I surveyed the local species pool. Then I described species assemblages using an integrated synusial approach to build up a qualitative model of the spatio-temporal dynamics of plant communities. Structural and functional attributes of plant diversity were then quantitatively described. A secondary forest ressembling the old-growth develops as soon as 30 years after field abandonment. This forest may recover structure and function during the fourth decade of recolonization and species composition one decade later. The invasion by Chromolaena odorata did not appear to slow down the succession. I found a deterministic succession consistently with predictions of both the niche theory and the tolerance model. However hazard plays a role especially in the earliest stages of the succession that seem to be sensitive to historical factors

Full textIn west africa, the peoples living in the countries of benin gulf (ghana-nigeria benin-cote d'ivoire-togo) are alike, sharing the same civilizations and facing the same problems. All of those countries have agriculture as the main and fundamental economic activity. Since independence, they have been victims of an inadequate political development which made agriculture play a secondary role. As a result, the agricultural production has declined seriously. It's rate of increase is less than that of the population growth (2% against 3,2%). From this, it resulted a chronic food shortage, misery and poverty. In that situation, the new agricultural development strategies are carried on at first, by information which is a prime necessity resource. So far, the democratization process in progress in those countries enhance an emergence and the development of media which are a powerful and an efficient means to reach the peoples, mostly those living in the rural areas. Being aware of those realities, fao as a reliable source of information, cooperates tightly with the media in order to put information and communication in the service of the peoples for a sustainable agricultural development, a healthy and nutritive feeding

Full textThe cocoa crisis of the late 1970s greatly affected the survival strategies of producers. It manifests in the scarcity of production (land, labour), the decrease in production and revenue, the transformation of the ecological milieu and the decrease in rainfall. In order to overcome these constraints, producers have adopted various strategies that either aim at diversifying their sources of revenue or reduce family responsibilities. The main result of this study is the observation that, the most efficient of these strategies were those shaped while taking into consideration social relationships. They include strategies to diversify revenue, credit, mobilisation of the labour factor, the respect of guidance rules. The diversification of revenue which was based on solidarity and cooperation constitute an important element of the producers’ survival strategies because they have ensured an ineligible first degree security in cocoa crisis
