Barro, Maimouna. "Three essays on challenges facing agriculture in developing countries". Electronic Thesis or Diss., Université Clermont Auvergne (2021-...), 2024. http://www.theses.fr/2024UCFA0004.
Texto completoAgriculture plays a major role in the economy of developing countries where the majority of the population lives in rural areas and depends on agriculture and food systems for their livelihoods. This population is also faced with numerous challenges such as climate change, poverty, environmental degradation or food insecurity. The objective of thethesis is to shed new light on the issues related to agriculture in order to derive economic policy recommendations. The thesis consists of three chapters. Chapter 1 assesses the impact of adopting irrigation on household and women’s dietary diversity. The study focuses on Sub-Saharan African (SSA) countries, particularly countries of the WestAfrican Economic and Monetary Union (WAEMU) where the share of the population suffering from moderate to severe food insecurity is very high. Our identification strategy is based on the entropy balancing method developed by Hainmueller 2012. The results show that irrigating households have higher dietary diversity scores compared to non-irrigating households. In addition, the results also reveal that women in irrigating households have higher dietary diversity scores than women in non-irrigating households. Furthermore, these findings highlight that women’s empowerment, increased agricultural income, production, and water supply are potential mechanisms through whichirrigation contributes to improving dietary diversity.Chapter 2 focuses on the relationship between malaria prevalence and agricultural labor in the context of irrigation and family farming in SSA. The goal of this study is to analyse the impact of malaria on agricultural labor (quantity and productivity) by highlighting someunderlying mechanisms that explain the relationship between malaria and labor in African family farming. More precisely, we focused on irrigation and household size as two potential moderator variables of the impact of malaria on labor. On the one hand, the results show that malaria has a negative impact on labor quantity. This effect is a direct health impact through the loss of workday due to the disease. However, once malaria interacts with irrigation or household size, its effect turns out to be insignificant. We explain these results by the presence of a moderating effect of irrigation and household size. On the other hand, the baseline and robustness results reveal that malaria increases labor productivity. We explain this result in the context of the productive inefficiency of African family farming. Regarding the moderating effect of irrigation, we do find a negative impact of the interaction of malaria with irrigation while few are robust. Overall, our results highlight that malaria remains a constraint in family farming in Africa.Chapter 3 examines the issue of industrialization in rural areas. More specifically, it analyzes the impact of industrial water pollution from manufacturing firms on rice production in Jiangsu, China. This study aims to disentangle this complex relationship by using a translog production function model. This model allows us to separate the directeffects of industrial water pollution on rice cultivation from its adaptation effects. Our results confirm that rice yields are negatively impacted by industrial water pollution through a direct biological effect. This detrimental effect is the most significant within a radius of 5 kilometers from the county center. In response, farmers use more operating costs to mitigate the negative impact of industrial water pollution. The changein production behaviors helps farmers to better cope with industrial development and adapt to the changing rural environment. Our study highlights the need to better understand the nexus between industry and agriculture at the local level

Texto completoIn this thesis, we stand a very fruitful idea: the concept, which is the « engine » of philosophical abstraction, no longer allows to shed light on the issue of philosophical debate in black Africa. However, this issue, though veiled by the flatness of the philosophical concept functions within what we called «the phenomenon of cultural conflicts of». To mount the validity of our thesis, we favored a simple method that uses two black African novels (Cheikh H. Kane’s L’aventure ambiguë and V. Y. Mudimbe’s Entre les eaux) to illuminate cultural conflicts in black Africa. It has been shown that the "clash of cultures" was synonymous with "intellectual conflict" for the black African philosopher. By analyzing the discourse of the African philosopher, whose style refuses failures and hesitations, it became clear that he had to escape the pitfalls of this discourse to find for himself an "outside", able to enlighten. The above two novels, that we have systematically analyzed in the first part, helped to deconstruct the discourse of the African philosopher, and finally made us see the symbolic contradictions of "philosophizing in Black Africa".The second part of this thesis tries to think of Africans within a world that keeps changing ; that is, in a word, trying to admit the African Negro in a story that restores to the positive utopia all its meaning. In this respect, the crossing of Bidima reintroduces, in the discursive practice in black Africa, the very possbility of refusing identity assignments and blissful substantialismes: Black Africa is not a frozen continent ; it is rather inscribed in a time that brings ever new things

Texto completoThe basin of the Senegal river has been recently the subject of hydro-agricultural equipment (like the dam of Diama and the dam of Manantali). These equipment have been conceived, in order to promote the irrigate cultures of diversification mainly, especially the rice irrigated culture. However, the functioning of the different hydro-agricultural systems is conditioned by mainly constraints of the social, sanitary, and natural environment, including the climate. Among the climatic constraints we find according to the stations and the seasons: diurnal strong heat and by cold nights, worm and dry winds, and important losses in water because of the evapotranspiration, rainfall, etc. The agroclimatical challenges have been studied, mostly the problems of the choice and settlement of the cycles of the irrigated culture. The frequantial analysis of the data and or the numeric simulation have made it possible to detect on one hand the climatic optimal dates for the cultures and on the other hand the rice varieties which genetic properties are tolerant of not with the atmospheric stresses. The whole results have allowed to distinguish two types of gradients: an e-w gradient which brings differences between littoral stations, semi-continental stations and continental stations then a n-s gradient which opposes the sites of the Sahel and its peripheries

Texto completoThe study of the cocoaplanters'behaviour in Cameroon during a period of economic instability and unruliness sets at once the following question : is there still a future for the cocoa plantation ? This study attemps to answer the urgent problems of national policy. Indeed, cocoa -which represents 15% of export profits- is one of the most important commodity for economic take-off in Cameroon. Following interviews with farmers about their decisions just before and after the devaluation of the fcfa, we tried to surround the agronomical and social vulnerabilities which are characteristic of various cocoa production systems, in order to appreciate how much the instability coming from outside (price variability, access to credit, changes in agricultural policy) can affect those farmers and to come to the real conditions of decision taking of the planter. Based on decision making criteria towards risk and uncertainty, gleaned from the empirical study, a linear programming model was developed in order to test the logics of agricultural supply under different constraints and macro-economic management interventions. The uncertain factors as they are considered in the model, are not only a constraint, but limit the amount of the knowledge that is possible to have of the future and also influence on the ratio between consumption and saving. Over the whole set of simulations, decision making risk seems to be a strong factor in discouraging investment since, due to price instability, the possible gains achieved by taking risks are questionable from one year to another. Conscious of such uncertain events, the cocoa planter will tend to economize -precaution savings- in order to survive through periods of low price and low yields

Texto completoThe aim was to review French discourse from the dawn of the twenty-first century ; more particulary in the following texts : The Initiated, The cry that you make won't awaken nobody, The Festival of Masks, After the silence, In waiting for the vote of the Wild Animals, The sound of Inheritance, The Identity Card and The one and a helf lives. In the end, after considering the question of traditional powers from each and every perspective, it is the problem of identity, in all its facets, which has been dealt with. Seen from this point of view, the (written and spoken) word has been pinpointed as a source of power in consideration of its social and literary aspect. The question of myths and their stylistic effect of their images have allowed us to highlight the way in which all the elements constituting ancient knowledge have been handed down over time. Myths, which, by means of the narrative structure of their texts, have revealed how contemporary literary works, destroyed by contemporary societies, are affected and they contribute also to to the breaking down of traditional orders. Following on from that, there is an attempt to legitimise Frecnh writings by means of the power of words, as writing of rupture. In order to do this, it was necessary to highlight the structural elements which would help us to define French texts on the basis of their linguistic elements. Subsequently, words have been denoted as a force which generates meaning. This semantic self-generation has helped to reveal the instability of certain characters and the apparent loss of authority bt patriarchs such as Rèdiwa or Makaya, charged with the safe-keeping and the transmission of ancient values. The internal conflict found in French black African imaginative works, often linked to the confrontation between tradition and modernity, is also that which has allowed us to read cultural phenomena differently and has led to the challenging of traditional knowledge. Finally, the entire French-speaking world, or at least that which is mentioned in the third part of this work, eventually reveals itself to be, in one way or an other, based almost exactly on the ancients' model. The analysis carried out during this work has shown how the political arena and the traditional axis of power became interdependent. Political figure circulated freely, moving from one area to another in their pursuit of meaning, without the slightest apprehension. This pursuit of meaning or of identity has led political heroes, seeking to flee everyday difficulties, to make us of the ebb and flow of symbolism and politics in order to construct new identities, new beliefs, and in order to construct a new basis for the relationships with the other, with society and with the universe. If the reading about figures of traditional power has been thus effective, it is because this model has become the matrix of French writings. This attachment to values has given the issue of modernity a dual quelity : on the one hand in terms of being a national treatment of the subject liberated from the pitfalls of nature ; and on the other hand, one which is perceived as the establisment of the new tradition. In each of these two cases, French novelists have tried to make their characters and their writting adhere to this vision of things

Cas du sorgho et du niébé dans l'environnement soudano-sahélien". Electronic Thesis or Diss., Sorbonne université, 2022. https://theses.hal.science/tel-03847646.
Texto completoIn the Sudano-Sahelian zone of West Africa, agricultural productivity is strongly affected by climate variability and change. Agricultural production is dominated by rainfed cereal production such as maize, millet and sorghum for food consumption. Farmers have small and variable yields, leading to increasing uncertainty about their ability to produce more to feed a rapidly growing population. The aim of this thesis was to design more productive and stable cropping systems, adapted to climate change, by exploring the benefits of sorghum-cowpea intercropping, combined with contrasting choices of sorghum variety, mineral fertilisation and sowing date. The approach was based on a survey, field experimentation and simulation using a crop model, for a case study in central Mali in West Africa. The first step was to identify farmers' perceptions of climate change and the agricultural adaptation strategies they consider relevant to cope with climate variability and change. Secondly, the STICS crop model was calibrated on the basis of two years of experimentation (2017, 2018) of the sorghum-cowpea intercrop at the N'Tarla agronomic station. In this experimental set-up, two sorghum varieties (local and improved) with contrasting sensitivity to photoperiod were studied in sole crops and in intercropping with cowpea. Two sowing dates and two levels of mineral fertilisation were also studied. The relevance of the model to represent competition and complementarities between sorghum and cowpea fo water and nitrogen use was evaluated. Finally, the performance (average productivity and productivity stability of a range of technical options for integrated soil fertility management

Texto completoIn a sahelian region made more precarious by the persitent drought, the new use of dams seems to reassure decision-makers, who in irrigated culture, see the best means self-sufficieney in food. Yet, the development of this technology in an environment, which, up to now, is ignorant of hydro-agricultural traditions, implies good quality training capable of making it popular. . . So, in this study centered upon the mauritanean bank of the middle valley of the Sénégal river, we try and show the risky aspect of irrigation just now. This situation is the result of a lack of good training. The variable technico economy element predominates, whereas the human dimension, the real countrymen's participation are neglected.
