This dissertation consists of three chapters that address two major resource challenges faced by smallholder farmers in Sub-Saharan Africa: (i) weather shocks and (ii) limited land access for agricultural production. The first chapter looks at how weather shocks affect millet production and millet market price seasonality in Niger. In this paper, we use district-level longitudinal production and price data, along with high-resolution rainfall data to investigate the distinct impacts of positive and negative rainfall shocks on millet production and millet price seasonality in Niger. We find that a one standard deviation decrease in seasonal rainfall from historical averages is associated with declines in millet market price initially after harvest, but strong upward pressure on market prices 6 months after harvest. As a result, drought exacerbates existing price seasonality, which in turn can amplify negative impacts on households. Social protection programs need to account for potential increases in seasonal price variability in the design of programs to enhance household resilience to weather shocks. To better understand the household behavior that gives rise to the price responses observed in the first chapter, we explore weather shock impacts on household millet market participation in Niger in the second chapter. We merge a nationally representative household panel data with high-resolution spatially disaggregated rainfall data. We find that households are more likely to participate in the market as net sellers with negative rainfall shocks, but marketed quantity for net sellers decreases with negative rainfall shocks. Diversification into non-agricultural activities can mediate the impacts of negative rainfall shocks on market participation and lead to increases in volume of sales. Policies that support household involvement in the rural nonfarm economy through training and access to credit to help expand businesses may also stimulate millet market participation. In the third chapter, we use a rich dataset of 1,123 households to examine the determinants of individual household member access to groundnut fields, the predominant cash-crop in the Groundnut Basin of Senegal. The analysis also explores the implications of limited land access on groundnut productivity of young adult and female field managers. We find that young adults and females have fewer opportunities to access land compared to older and male household members. Further, we show that higher productivity may not be driving differential access to fields among older adults. Results suggest that with equal access, young adults may be as or more productive groundnut cultivators than older adults. Programs to increase young adult and female economic opportunities should focus on closing gaps in access to resources for production rather than decreasing observed production disparities. / Doctor of Philosophy / This dissertation addresses two major challenges that small farmers face in Sub-Saharan Africa: (i) erratic changes in weather patterns and (ii) land access for agricultural production. We divide the dissertation in three chapters. The first two chapters focus on weather shocks, while the third chapter focuses on land access. In the first chapter, we discuss how low and high rainfall affect the seasonal variation of market prices for the most important staple grain (millet) in Niger (West Africa). We find that lower rainfall than usual makes households sell their millet in the post-harvest period when market prices are generally low, and makes them buy back millet in the lean season when market prices are often high. As a result, policies that aim support household resilience to climate shocks should design programs that account for potential increases in seasonal price variability. In the second chapter, we study how low rainfall levels affect Niger millet farmers' decision to sell or not sell their harvest, as well as the association between low rainfall and the quantity of millet sold and bought. We distinguish three groups of farmers: (i) net buyers who have higher millet purchases than sales, (ii) autarkic who have zero millet purchases and millet sales, and (iii) net sellers who have higher sales than purchases. Our findings show that lower rainfall increases net sellers' probability to sell their millet, whereas it decreases the quantity they sell. Our results also reveal that households who diversify their sources of income into non-agricultural activities increase millet net sales even with low rainfall levels. Policies that support household involvement in these non-agricultural activities may also stimulate millet market participation. In the third chapter, we study the factors that affect household members' access to a groundnut field in Senegal with a particular focus on young adults and females. We show that females and young adults are less likely to access a field compared to older and male household members. Our results also suggest that with equal access, young adults may be as or more productive groundnut cultivators than older adults. Programs to increase young adult and female economic opportunities should focus on closing gaps in access to resources for production.

The oriental fruit fly, Bactrocera dorsalis Hendel, is an economic tephritid that invaded Senegal in 2004 (Vayssieres et al. 2011). This work determined 1) Impact of B. dorsalis on mango crop production and value, and marketing practices, 2) Effect of neem and kaolin on its behavior and development (laboratory and field), and 3) Effect of treated soil with neem seed cake (NSC) and neem seed powder (NSP) on the larval-pupal survival and development (laboratory and field). Results revealed crop value (price/kg) was associated with infestation levels. P<0.0001, crop value decreased in highly infested orchards. Southern Orchards were heavily infested than northern orchards. Early harvest, orchard sanitation, decreasing the purchase quantity, sorting infested mangoes and lowering prices were strategies used by growers and traders. Laboratory bioassays showed females landed and spent time on fruit identically on control and neem. On kaolin there were fewer landings and less time spent. P<0.0001, mean pupae was higher in control than in treated mangoes. In the field, percent of infested mangoes was higher in neem than in control and kaolin. However, the number of emerged flies was higher in the control than in either the neem or kaolin-treated fruit. Treated soil with NSC and with NSP did not have effect on pupation; all larvae pupated in the lab. However, treated soil decreased significantly the number of emerged flies. In the field, there were no significant differences between untreated and treated soil in number of emerged flies. / Master of Science in Life Sciences

In Senegal, in recent years the rural sector has undergone major reforms which are partly due to macroeconomic policy reforms adopted by the Senegalese government. Therefore, all the actors of economic and social development have a common concern and share in promoting rural agriculture (Bernard et al., 2008). Changes observed in the agricultural and rural sector reflect the will of the actors to have a productive, competitive, and sustainable agriculture system in order to ensure food security (International Monetary Fund, 2011). The purpose of the study is to develop a set of recommendations to improve the educational program planning and teaching skills of educators in the extension system by focusing on extension educators' approaches to teaching farmers and cart owners animal welfare practices for proper care of working animals. The extension agents and teachers involved in the animal husbandry and animal extension system in Thies and Bambey served as participants in this study. This descriptive qualitative study connected qualitative data derived from participant interviews, qualitative document analysis, observations of an educational program planning professional development program for state agents and university faculty members in Diourbel and Thies regions, as well as a final focus group to allow participants clarification of preliminary themes found in the data. The findings revealed 11 themes: characteristics of the participants, job expectation and responsibilities, institutional and organizational factors, capacity building and professional development plans, diagnostics of the extension system, regulations and legislations, limited sources of information, limited knowledge and skills technologies, recommendations for utilizing student-centered teaching practices, standard welfare for animal husbandry, recommendation for acceptance and improvement standard animal welfare related to the four research questions which addressed the topics of challenging current teaching methods used in the extension system for other owners of animal species in the animal extension programs, the use of student-centered teaching practices in extension education and university instruction, and the level assistance given to farmers in order to ensure accepted standards of animal welfare working animal and other animal species in the animal husbandry system. / Master of Science in Life Sciences / In Senegal, in recent years the rural sector has undergone major reforms which are partly due to macroeconomic policy reforms adopted by the Senegalese government.

Organic matter (OM) is a multi-purpose tool in West African smallholder mixed-farming systems, but its supply has been decreasing for several decades. To assess the viability of a mixed-farming system of south Senegal, carbon (C), nitrogen (N) and phosphorus (P; available in soil and noted POD) budgets (stocks and flows) were thus quantified.The village territory of the study showed a ring-like organisation with growing intensification of fertilization and cropping practices from the periphery (bush ring) to the compounds (compound fields).Stocks in plant and soil averaged 54.7 tC, 2.63 tN and 43.5 kgP ha 1 in old fallows. They were 97, 29 and 251 % higher than in the bush cropped fields, plant biomass accounting for nearly all of the rise. C, N and P amounts recorded in the soil of compound fields were higher than those of the bush field, but the increase was restricted mainly to the 0 10 cm layer. However, the rather weak response of local sandy soils to management can be interpreted only by reassessing the bio-thermodynamical signification of soil organic carbon cycling in the maintenance of the integrity of local agroecosystems.Manageable stocks of the whole village territory were estimated to 29.7 tC, 1.52 tN and 28.6 kgP ha 1 in 1997. Carbon was stored mainly in soil. Livestock, crop harvest and wood collecting were responsible for respectively 59, 27 and 14 % of the C uptake on the village territory. As a result, large C flows were set towards the compound ring (3.8 tC ha 1 y 1). N and P depletion of the system amounted to 4 kgN and 1 kgP ha 1 y 1, suggesting that the system was close to nutrient balance.Under current demographic growth rate, C depletion may reach 0.38 tC ha 1 y 1 and C demand may double during the next three decades. Without any intensification of farming practices, the viability of the system might soon be called into question.

Cette thèse analyse à travers une étude de cas, le parcours d’un programme de micro-crédit rural mis en place par l’ONG Plan International, transformé en institution formelle et intégré aujourd’hui dans l’un des plus grands réseaux mutualistes du Sénégal : l’UM-PAMECAS (Union des Mutuelles du Partenariat pour la Mobilisation de l'Epargne et du Crédit au Sénégal). Notre objectif était de montrer comment les organisations de microfinance concilient les logiques sociale et financière, à priori en opposition, dans leur mode d’action après une transformation institutionnelle. Compte tenu de la diversité des règles et des modes d’actions observés au sein des organisations étudiées, nous avons mobilisé l’économie des conventions pour construire notre cadre d’analyse. La thèse s’appuie sur une analyse qualitative diachronique des logiques en présence, de façon à comprendre ce qui les soustend, les mécanismes et enjeux de pouvoir qui les font évoluer et se stabiliser. Sur une période s’étalant de 2006 à 2008 nous avons mené des enquêtes auprès de 169 personnes aux statuts divers (salariés, élus, bénéficiaire des crédits, etc.). Ce travail a apporté un éclairage sur le processus de transformation institutionnelle des organisations de microfinance rural et ses enjeux. Nous avons montré que grâce à une méthodologie combinant plusieurs principes relevant de cités différentes mais essentiellement rattachés à une « logique sociale », les organisations de microfinance de premières générations ont permis à des personnes vivant en milieu rural, dont le profil socio-économique n’intéressait pas les banques commerciales, d’accéder aux services financiers. La transformation institutionnelle induite par des facteurs exogènes et endogènes a apporté des bouleversements auxquelles les organisations devaient faire face pour assurer leur pérennité. Notre recherche a montré que pour réussir cette transition et éviter des conflits, des concertations doivent être menées tout au long du processus avec l’ensemble des acteurs afin que tous s’entendent sur le but de la transformation, la façon dont le processus doit être mené et les réformes à mettre en place. En outre, les nouvelles procédures mises en place doivent être en adéquation avec les spécificités locales. Par ailleurs, cette thèse a montré la forte prédominance des tontines. Ces dernières ont fortement évolué et se sont enrichies grâce à l’hybridation de règles marchandes, domestiques et civiques qui en font aujourd’hui, des dispositifs locaux concurrençant fortement la collecte de l’épargne au niveau des structures formelles / This thesis analyses, trough a case study, the operation of a rural micro-credit program implemented by Plan international NGO. It has then been changed into a formal institution and integrated into one of the largest network of mutual organizations in Senegal: UMPAMECAS. Our objective was to show how micro-finance organizations reconcile social and financial logics that are primarily contradictory, in their action after institutional changes. Considering the diversity of rules and operation modes observed in the institutions under scrutiny, we have mobilized the convention economy to build the framework of our analysis. The thesis is based on a diachronic quantitative analysis of those logics to understand what underlies them, power mechanism and stakes that make them evolve and stabilize. For a period from 2006 through 2008, we surveyed 169 people from different (wages-earners, elected, credits beneficiaries, etc.). This work has cast light on the transformation process of rural microfinance and its stakes. We have shown that, thanks to a methodology combining several principles from different cities, but essentially related to a “social logic”, the first generation of microfinance institutions have enabled several people living in rural areas, whose economic profile did not appeal to commercial banks, to get access to financial services. The institutional transformations induced by endogenous and exogenous facts have brought changes which should be dealt with by the institutions to ensure their sustainability. Our research has shown that to survive the transition and avoid conflicts, consultations should be conducted all through the process with all the stakeholders for all to agree on the objective of the transition, the way the process should be conducted and the reforms that need to be implemented. Besides, the newly implemented procedures should match local specificities. Furthermore, this thesis has shown the supremacy of the “tontine” systems (rotating saving and credit associations). Those systems have deeply evolved and enriched due to the hybridization of commercial, domestic and civic rules that make them today local organizations that strongly challenge formal structures in the collecting of savings

Les technologies de l’information et de la communication ont fait naître beaucoup d’espoir, en Afrique, dans tous les domaines de la vie économique et sociale, et, surtout dans celui de l’éducation. Pour l’enseignement supérieur, cet espoir est d’autant plus grand que les besoins et défis à relever sont très nombreux. L’université africaine est confrontée à toute une série de problèmes : massification des effectifs d’étudiants surtout au niveau des premiers cycles, insuffisance des locaux pédagogiques et manque d’enseignants qualifiés à un nombre suffisant et des moyen financiers insuffisants, les trois premiers problèmes évoqués ne sont en réalité que la conséquence logique des difficultés budgétaires. L’autre problème majeure, c’est la problématique de la pertinence même des curricula de formation proposée, les jeunes issus des universités africaines n’arrivent pas à trouver un emploi. C’est dans ce contexte que les NTIC apparaissent comme une solution possible pour aider à résoudre ces difficultés. Dans cette lancée, à l’instar des autres pays de la sous région, le Sénégal tente d’utiliser ces technologies pour réformer et améliorer son système d’enseignement supérieur. En effet, avec l’augmentation du nombre de collèges au niveau de l’enseignement secondaire, la massification des effectifs d’étudiants exerce une forte pression sur les autorités universitaires. Avec les importantes réalisations réalisées dans le domaine de l’informatique et de la connectivité internet de l’UCAD, les conditions difficiles d’accès liées à la massification des effectifs surtout au niveau des premiers cycles, sont-elles en voie de trouver une solution ? / Information and communication technologies have borne much hope in Africa in all areas of economic and social life and especially in education. For higher education this hope is all that greater needs and challenges are many. The African University faces a threefold problem: mass numbers of students primarily at the undergraduate level, lack of educational facilities and lack of sufficient qualified teachers in a number. It is in this context ICT appear as a possible solution to overcome resolve these difficulties. On this momentum, with the other countries of the sub region, Senegal tries to use these technologies to reform and improve its higher education system. Indeed, with the increase in the number of colleges at the level of secondary education, the mass of the numbers of students exerts strong pressure on the University authorities. Each year, thousands of young graduates knock at their doors; It was then that ICT and e-learning appear as alternative to solve this equation trimmed of all virtues With the significant achievements in the field of computing and internet connectivity of UCAD, are difficult access conditions related to the mass of staff especially at the undergraduate level on the way to be solved?

Le Bayefallisme est une branche à l'intérieur de la voie soufie de Mouridiyya qui met de l'avant l'importance du travail pour les autres. Les disciples Baye Fall sont majoritairement sénégalais et renégocient leur rapport aux pratiques islamiques telles que la prière rituelle et le jeune. À l’instar de Pézeril (2008), l’enjeu de notre enquête ethnographique est de « comprendre » les Baye Fall. Notre recherche vise à mettre en lumière leurs expériences religieuses à l'aide d'une méthodologie d'observation participante qui tient compte de la présence du chercheur sur le terrain (Turner, 2000) et accorde donc une place importante à la réflexivité (Fabian, 2001). Nous avons remarqué que la majorité de nos informateurs ne déclaraient pas clairement : « Je suis Baye Fall », mais plutôt : « Je veux être Baye Fall ». Cette posture, que nous qualifierons de bayefallisante, nous a tout d’abord semblé problématique pour ensuite devenir notre porte d'entrée. La littérature sur les trajectoires religieuses a déjà démontré qu'elles ne sont pas linéaires, mais remplies d’ambivalences et de contradictions. Pour Schielke (2009) et de Koning (2013), ces contradictions sont induites par les ruptures inhérentes au quotidien en contexte de globalisation. Notre objectif est de démontrer que ces ambiguïtés peuvent également être créées par la qualité intersubjective et réflexive de l'expérience religieuse.Alors que les Baye Fall ont été ethnographiés surtout au Sénégal (Audrain, 2004; Pézeril, 2008; Morris, 2014), notre recherche a l'originalité de rendre compte d’un phénomène de bayefallisation des disciples mourides dans le contexte montréalais. / Bayefallism is a sub-group of the Mouride brotherhood that emphasizes hard work and dedication. Baye Fall disciples are mostly Senegalese and they challenge well-known precepts of Islam such as those prescribing daily prayers and fasting. Like Pézeril (2008), I aim at a better “understanding” of the Baye Fall in this study. My research aims to shed light on their religious experience through a methodology of participant observation where the presence of the ethnographer (Turner, 2000) is taken into account and that gives an important place to reflexivity (Fabian, 2001). Most of my informants did not say “I am Baye Fall”; rather they said, “I would like be Baye Fall.” Initially, I saw this as a problem but it soon became the starting point of my research. The literature on religious trajectories has shown that such trajectories are not linear but charged with ambivalence and contradictions. For authors such as Schielke (2009) and de Koning (2013), these contradictions are engendered by certain ruptures that are part of daily life in a globalized context. In my study, I seek to demonstrate that these ambiguities can also be an integral part of of an intersubjective, reflexive religious experience. While ethnographies of Baye Fall have been mainly carried out in Senegal (Audrain, 2004; Pézeril, 2008; Morris, 2014), the originality of this research lies in the fact that it examines the phenomenon of Bayefallism in the context of Montreal.

Le Sénégal est situé dans une zone soudano-sahélienne particulièrement exposée aux changements du climat, ce dernier rendant l’agriculture, activité principale du pays, précaire. La modification des conditions climatiques, en particulier depuis la fin des années 1960, a fortement affaibli le secteur agricole, majoritairement vivrier et pluvial. Face à l’importance de l’activité agraire vivrière du pays, il apparaît primordial de savoir comment les agriculteurs vivriers du Sénégal ont modifié ou prévoit modifier leurs pratiques en vue de satisfaire leurs besoins alimentaires dans un contexte de changement et de variabilité du climat. Cette étude a été effectuée au sein de la communauté rurale de Sessène selon une approche qualitative et à l’aide d’entretiens, de l’observation participante et d’analyse phénoménologique. Elle a permis de mettre en avant les caractéristiques générales des familles agraires et des exploitations de cette zone, de montrer comment les agriculteurs ont vécu le changement climatique et comment ils envisagent les prochaines années et enfin de discuter de leur capacité d’adaptation. Face au raccourcissement de la saison des pluies, à la diminution des précipitations, à l’intensification des évènements extrêmes et aux impacts de ces modifications sur l’environnement naturel, les agriculteurs vivriers adoptent des mesures aussi bien techniques que socio-économiques. / Senegal is located in a sudano-sahelian region vulnerable to climate change that renders agriculture, the country's main activity, precarious. In fact, changing climate conditions, particularly since the late 1960s, have considerably weakened the agricultural sector, which is mostly subsistence and pluvial in nature. Because of the importance of the country’s subsistence agriculture, it is imperative to know how subsistence farmers in Senegal have changed or will change their practices in order to satisfy their nutritional requirements in the context of climate change and variability. This study was undertaken in the rural community of Sessène using a qualitative approach composed on interviews, participant observation and phenomenological analysis. The research revealed the general characteristics of the agrarian families and farms, demonstrated how farmers dealt with climate change in the recent past and how they envisage doing so in the next few years, all aimed at contributing to a discussion of their adaptive capacity. In response to the shortening of the rainy season, the decrease in rainfall, the increased frequency of extreme events and the impacts of these changes on the natural environment, subsistence farmers are adopting both technical and socio-economic measures.

La présente recherche vise à explorer et à décrire l’accommodation des valeurs professionnelles au sein du système de valeurs culturelles par les bibliothécaires universitaires sénégalais. Elle répond aux questions de recherche suivantes : (1) Quel est le système de valeurs culturelles dominant chez les bibliothécaires universitaires sénégalais ? (2) Comment les bibliothécaires universitaires sénégalais priorisent-ils leurs valeurs professionnelles ? (3) Comment les bibliothécaires universitaires sénégalais accommodent-ils leurs valeurs professionnelles à leurs valeurs culturelles ?cette recherche confirme la théorie de la prédominance dans les sociétés africaines en général d’un système de valeurs s’inscrivant dans l’axe « Continuité – Dépassement de soi » du modèle théorique de Schwartz (2006, 1992). Dans ce système, les valeurs dominantes sont des valeurs de types universalisme, bienveillance, tradition, conformité et sécurité. Ces valeurs favorisent l’intégration de l’individu au groupe, la solidarité et la sécurité familiale et le refus des actions de nature à porter atteinte à l’harmonie du groupe. Au plan pratique, la recherche démontre la nécessité de renforcer la socialisation professionnelle en intégrant l’éthique et les valeurs dans la formation des bibliothécaires universitaires sénégalais. / A profession basically includes two components: scientific skills and professional values, which are the guidelines of professionals’ daily demeanor. The library profession is based on values like the preservation of humanity cultural heritage, a fair access to knowledge, intellectual freedom, confidentiality and the protection library users’ private lives, professional neutrality, tolerance etc. In Senegal as well as in the other African countries, libraries are, on the whole, legacies of colonialism. The values of library science were designed in a western perspective. This profession value system may sometimes conflict with the Senegalese librarians’ cultural value systems. However, very little is known on ways Senegalese professionals cope with these two value systems. This present research will describe and explore the interactive co-existence and adaptation of professional values within the cultural value system of Senegalese academic librarians. It seeks to answer the following research questions: (1) what is the Senegalese academic librarians’ dominant cultural value system? (2) How do Senegalese academic librarians prioritize their professional values? (3) How do Senegalese academic librarians adapt their professional values to cultural values? This exploratory and descriptive analysis combines a mixed methodology approach: Two types of data collecting methods have been used: a questionnaire based on interviews and on Schwartz’s Portrait Values Questionnaire (PVQ) (Schwartz, 2006) The findings highlight the fact that, on the cultural level, Senegalese academic librarians essentially emphasize, in the value system, the interests of the social group they belong to, the respect of social order and adoption of normative behavior in order to facilitate their relationships with the other group members. The values favor a strong integration of the individual into a group but do not encourage an action and thought autonomy which may destroy social harmony. On the professional level, they regard access to information, preservation and conservation of heritage and the denial of all sorts of discriminations as essential professional values. As professional values conflict with cultural norms, Senegalese academic librarians often seek a compromise, a balanced position to make decision which does not basically question their cultural values. When a compromise is impossible, the final decision is made in favour of cultural values. On the theoretical level, this research confirms the theory of a value system predominance rooted in Schwartz’ perspective of the “continuity/self-transcendence” (Schwartz, 2006, 1992). In his system, the dominant values are universalism, benevolence, tradition, conformity and security. These values favor the individual’s integration into a group, solidarity and family security and the refusal to undertake actions which may endanger group harmony. On the practical level, this research displays the necessity to reinforce professional socialization which includes ethics and values in the training of Senegalese academic librarians.

A travers cette thèse, nous avons saisi des expériences féminines qui sont à l’oeuvre dans la société sénégalaise. De telles expériences qui sont souvent perçues comme « transgressives » par les figures de l’autorité masculine sénégalaise (acteurs religieux et entrepreneurs moraux par exemple) permettent de mettre à jour un Sénégal situédans les tensions d’une glocalisation. Nous avons analysé ce Sénégal comme le site d’une négociation entre ses principes visibles (vertu, morale, tolérance, tradition, etc) et des pratiques de femmes, qui n’ayant plus peur de sortir des canaux de socialisation, explorent de nouvelles subjectivités. Face à ces tensions, prime une culture del’ambivalence incarnée à la fois par les médias, les acteurs moraux et les figures étiquetées péjorativement. En d’autres termes, les médias sont souvent « créateurs » des visibilités « scandaleuses » et peuvent s’aligner derrière les acteurs moraux ou religieux pour défendre la vertu nationale ou l’image de la Sénégalaise. Pour les acteursmoraux, l’ambivalence se situe dans le fait qu’il existe un fossé entre leurs propres pratiques et les principes islamiques qu’ils incarnent et utilisent pour dénoncer des faits perçus comme « scandaleux ». Les figures « transgressives » mobilisent, quant à elles, une identification se référant aux identités religieuses et aux imaginaires sociaux pour ne pas trop s’écarter des cadres normatifs. Toutes ces ambivalences traduisent in fine l’ambivalence d’une société se définissant comme pieuse, vertueuse et « traditionnelle » mais qui est sans cesse débordée par les pratiques d’une jeunesse au diapason d’un monde globalisé. / This doctoral dissertation is an account of current female experiences I observed in Senegalese society. These experiences, often perceived as « transgressive» by Senegalese male authorities, namely religious and other moral guides, allow us to uncover a Senegalese society faced with the pressures of glocalization. Senegalese society is trying to negociate a balance between the preservation of fundamental principles (virtue, morality, tolerance, tradition, etc) and certain behaviours and life styles of women who are no longer afraid to free themselves from established socialization channels and explore new subjectivities. Faced with these tensions, a culture of contradictions is dominant as embodied through various networks namely the media, moral figures, and the female actors labelled negatively. In other words, the media is often the creator of scandalous characters and may support moral and religious figures in their defense of virtue, the country’s moral status, and the image of the Senegalese woman. For moral figures, the contradictions are marked by the fact that there is a big gap between their own practices and the Islamic principles they embody and use to speak against facts they perceive as scandalous. As for the « transgressive » actors, they find ways to relate to religious identities and social imaginaries so as not to distance themselves too much from social norms. All these tensions reflect the contradictions of a society that defines itself as « pious », « virtuous », and «traditional », but that is constantly overwhelmed by the practices of a younger generation in tune with a globalized world.
