Chronic respiratory diseases such as asthma and chronic bronchitis have significantly increased in prevalence in Africa over the past 10 years. Recent studies have demonstrated that exposure to air pollution may be associated with an increased risk of chronic respiratory diseases. However, such studies have predominantly been conducted in western societies or often used urbanicity as a proxy for exposure to air pollution. Therefore, we evaluated the association between PM2.5 exposure and asthma/chronic bronchitis in Senegal. A cross-sectional study was conducted for the time period of 3 October 2010 to 28 April 2011 using annual concentrations of PM2.5 measured via multiple satellite instruments, and asthma/chronic bronchitis, which was self-reported at baseline via a health survey questionnaire. We used mixed model logistic regression to evaluate the relationship between PM2.5 exposure and asthma/chronic bronchitis risk while adjusting for lifestyle factors, location, and other air pollutants. Sex was evaluated as an effect modifier. The adjusted association between PM2.5 and asthma/chronic bronchitis was 1.03 (95%CI: 0.99 – 1.06). In males the adjusted odds ratio was 1.09 (95%CI: 1.03-1.15), compared to females (aOR 1.01 (95%CI: 0.97 – 1.05). Our results suggest that increasing levels of exposure to PM2.5 puts individuals at a higher risk for chronic respiratory diseases, especially men. These findings have significant policy implications and should be built upon in future research.

<p>In Senegal, local communities have faced a wide range of economic and political challenges. In their attempt to address these issues, local and international non-governmental organizations (NGOs) have engaged in a wide variety of improvement projects, and have often partnered together in these efforts. This dissertation examines the linkages formed between Senegalese and international NGOs in their efforts to achieve their aspirations of improvement for the country in a context of global interconnection. By engaging with relevant literature and ethnographic data collected through anthropological research efforts, I seek to provide a more in-depth understanding of the perspectives and experiences of NGO practitioners in Senegal while considering the interrelated issues of global connection, civil society and social hope. My research aims to contribute to the anthropological discourse on NGOs by examining how practitioners engaged in a variety of NGOs in Senegal understand and approach their work and how they engage in the complex power relationships entailed by these international NGO partnerships. In addition, this study explores the issue of social hope among NGO practitioners, examining how they approach and experience the concept of hope through their NGO efforts at improvement. With a focus on implementing programs targeted at certain groups over a short period of time, the hope of NGO staff involves a desire for long-term change despite the challenges faced. This study also considers the aspirations of NGO staff with respect to their political engagement with the state and their perception of Senegal’s place in the world. This involves exploring their belief that civil society and NGOs are the basis for hope in Senegal rather than the state. In this context, NGOs seek improvement by working within the political and economic system, constrained and limited by the dictates of their external donors and their approach to social change.</p> / Doctor of Philosophy (PhD)

This dissertation positions Germaine Acogny’s Modern African Dance Technique (“the Technique”) as a mode of knowledge that reveals insight into nationalism, Négritude, modernism and perspectives on modernity during the early years of Senegal’s independence. By investigating the Technique in relationship to its historical context, this study aims to identify how cultural and political values, which comprise the Technique’s embodied knowledge, are evident in its aesthetic design and philosophical underpinnings. A hybrid methodological approach is employed that merges theoretical analysis with autoethnography. Fieldwork in Senegal, archival research, interviews and embodied practice informed this study. A new theoretical frame, Wòrándá, is introduced that contributes to existing theories on embodiment in African and Diasporic dance techniques and performance. The findings of this dissertation conclude that the Technique sits at the junction of African and Euro-American cultural templates, which coalesce in the production of a codified movement technique that both embodies and confronts constructivist influences. Correlations are suggested between the Technique, Africentric perspectives and cultural nationalism. The Technique also fulfills Léopold Sedar Senghor’s vision of métissage (cultural blending) and cultural progress. Each of these ideological influences underscores the Technique’s significance as a modernist intervention on the genre of neo-traditional African concert dance, as its progenitor seeks to challenge dominant expectations of the African body in dance. / Dance

The growth of a country depends on the improvement of its human resources. The TVET (Technical and Vocational Education and Training) system intends primarily to advance personal support and resources. Throughout education, people can build their knowledge, understanding, and skills to find a job. The TVET in Agriculture (ATVET) curriculum plays an essential role in designing interventions to deliver quality education, helping people increase productivity in the various agriculture sectors of economic activities, value chains, and associated occupations. The purpose of this research is to investigate what is necessisary to improve the agriculture technical and vocational education programs in Senegal by focusing on pedagogy and teaching strategies. Participants represented different ranges of teaching experience from five to more than ten years. The lead researcher interviewed two school directors and ten ATVET teachers. The interviews were semi-structured and were last from 30 minutes to one hour in Diourbel and Thies, Senegal. The researchers developed an interview protocol regarding the ATVET programs, implementation issues, and job market trends. The results showed that participants had various years of professional experience in the ATVET system and academic levels. All participants are well experienced and knowledgeable about working in strenuous physical and instructional conditions. The lack of infrastructure, equipment, and class facilities appears in the findings as significant problems. The deterioration of the resources such as human, material, financial and organizational influences the expected teaching outcomes because of insufficient and inadequate teaching and learning methods. Thereby, all authorities must consider the requirements and expectations of the the competency-based (CBA) program within the sustainability of the infrastructure, the learning environment, and the efficiency of maintenance to improve the technical context to guarantee practical and efficient administration of technological, environmental, and human resources. / Doctor of Philosophy / The growth of a country depends on the improvement of its human resources.

The TVET in Agriculture performs a fundamental function in designing interventions to deliver concerning training, making people boost productivity in agriculture sectors of economic activities, value chains, and associated occupations. The purpose of this research is to investigate what is needed to improve agriculture vocational and technical education programs in Senegal by focusing on pedagogy and teaching strategies to address the new and growing competency demands of the different value-chains within the agriculture system. Participants in this study were the teachers and administrators in the current ATVET programs. The lead researcher interviewed two school directors and ten ATVET teachers in Diourbel and Thies, Senegal. The researchers developed an interview protocol regarding the ATVET programs, implementation issues, and job market trends. The results showed that participants are well experienced and knowledgeable about working in strenuous physical and instructional conditions. The availability and quality of material resources such as teaching materials and class sizes pose problems in teacher satisfaction in the classroom to boost learning outcomes. Thus, the didactic equipment also remains insufficient and poorly diversified, which testifies the limited pedagogical approaches used in these structures. The deterioration of the ATVET resources such as human, material, financial and organizational influences the expected teaching outcomes because of insufficient and inadequate teaching and learning methods. Thereby, all authorities must consider the requirements and expectations of sustainability of the infrastructure, the learning environment, and the efficiency of maintenance to improve the technical context.

Drought, salinity, and low soil fertility have negative impacts on agricultural productivity, resulting in food scarcity and nutritional insecurity, particularly in Sub-Saharan Africa. Mungbean [Vigna radiata (L.) R. Wilczek] has seen increased interest as a short-duration and drought tolerant legume crop, capable of atmospheric N₂ fixation. Mungbean is a protein and iron-rich legume and can be used as vegetable or grain for human consumption or multipurpose crop. At present, few studies have simultaneously explored the best agronomic practices for mungbean cultivation and evaluated its potential for increasing crop yields via intercropping systems and improving soil fertility through biological N₂ fixation. To understand the agronomic practices and soil physical properties limiting mungbean production, the impacts of two mungbean cultivars (Berken and OK2000) with and without inoculation with Bradyrhizobium spp. grown in loamy sand and silt loam soils on mungbean growth and yield were investigated under glasshouse conditions. Promising results from this study led to the introduction of mungbean into pearl millet systems in Senegal and evaluation of the effects of intercropping on growth, yields, land equivalent ratio (LER), canopy cover estimates, and normalized difference vegetation index (NDVI). Finally, we evaluated plant growth and N₂ fixation of five mungbean genotypes grown in two soil textures using the ¹⁵N natural abundance technique leading to recommendations for those with the greatest overall benefit to the cropping system. The literature review shows mungbean often proposed as a strategic crop for increasing legume diversification within current cropping systems and providing increased food security as well as market diversification and economic sustainability. The greenhouse study revealed that OK2000 cultivar produced significantly higher yield when inoculated and planted on a silt loam soil than other treatments, indicating the importance of inoculation and soil texture in mungbean establishment. Intercropping mungbean and millet significantly (p≤ 0.05) increased combined yields (35% to 100% increase) and LER compared to sole millet cropping systems. Canopy cover estimates and NDVI values significantly increased up to 60% and 30%, respectively, in millet-mungbean intercropping over millet alone. The N2 fixation study showed that %Ndfa of mungbean was higher when grown in the loamy sand soil (27% increase). However, soil N uptake (235 mg plant⁻¹) and amount of N fixed (67 mg plant⁻¹) were greater in the silt loam soil. Among genotypes, IC 8972-1 significantly (p≤ 0.05) derived less N from the atmosphere (23%) but took more soil N (155 mg plant⁻¹) which yielded significantly greater dry biomass (7.85 g plant⁻¹) and shoot N content (200 mg plant⁻¹). The results from the N₂ fixation study indicated that choice of mungbean genotype can contribute to reducing N needs of agricultural systems. Overall, this research project demonstrated that mungbean has the potential for diversifying smallholder agriculture and adding biologically fixed N into soils, in line with transformative adaptation strategies being promoted for sustainable agriculture. Further research and development programs on good cultural practices, adaptation to cropping systems, and nutritional benefits for human consumption can promote mungbean cultivation in SSA. / Doctor of Philosophy / Global population growth is expected to reach 9.8 billion in 2050 while climate change is predicted to reduce food production. Sustainable solutions are needed for increasing food availability and satisfying nutritional needs under changing climatic conditions. Mungbean is a viable option because it is a legume crop capable of restoring soil fertility and has low water requirements. Mungbean also contains high levels of protein and iron and can, therefore, provide a nutritious and healthy food. Although the agronomic benefits of mungbean have been studied, best cultural practices and its impact on farming systems and soil fertility are scattered. The objectives of this research were to identify the best agronomic practices for mungbean production, assess its effects when grown together with millet, and measure its nitrogen contribution to the soil. The results showed that selecting the best genotypes to be grown in a particular soil texture can significantly increase mungbean growth and yield. In addition, incorporation of mungbean into cereal-based farming systems demonstrated its capacity for improving agricultural production in a low-input environment. Assessment of nitrogen fixation by mungbean showed that it can naturally add nitrogen into the soils, the most limiting plant nutrient, reducing nitrogen application needs. Thus, the ability of mungbean to diversify farming systems, improve soil fertility, and deliver nutritious food will provide agronomic, environmental, and economic benefits to farmers, especially in food-insecure households. However, exploitation of the full potential of mungbean won't be achieved without understanding the major factors influencing mungbean cultivation and production.

Rice is a staple crop for many countries around the world, and is one of the top three food sources globally. Many environments where rice is grown contain stressors likely to limit its growth and yield. In southern Senegal (Casamance region), rice is mainly cultivated in lowlands near estuaries where drought, salinity, acidity, poor soil fertility, and iron toxicity are the main limiting factors. In Casamance, average rice yield for local farmers is 1 to 2 tons per hectare (809 to 1618 pounds per acre), compared to worldwide average yield of more than 4 tons per hectare. The soil where our 2-year experiment (2014 and 2015) was conducted is highly saline-sodic and acidic, and the salt tolerant cultivar we grew yielded 3.4 tons per hectare in 2013. Our main objective was to increase rice yield. The water table height, salinity, and pH were measured weekly during the rice growing season, and the soil was described, sampled, and analyzed to better understand the water and soil resources. Two planting methods were tested: flat planting and planting on beds. Two soil amendments were compared with each planting method: biochar and crushed oyster shells, alone and in combination. An untreated control was included in the experiment. All plots were fertilized. Treatment effects on soil properties and yield were compared in a split-plot design. Plant tissue was sampled for elemental content. The water table was above the surface and was saline during half of the growing season in 2014, and decreased after rice grain head emerged. Planting methods and amendments did not have an effect on yield in 2014, but biochar amendment increased yield in 2015. In 2014, soil salinity and sodium decreased to below toxic levels late in the growing season in the flat plots but not in the bedded plots. Therefore, flat planting is more appropriate in these lowland rice production systems. Soil pH increased from 4.4 to 7.7 in flat planting where biochar+shell was applied. Soil available nutrients such as P, Mn, and Zn were significantly higher in flat planting compared to beds. Toxic levels of Na (> 2000 milligrams per kilogram) were measured in leaves sampled just before flowering. We recommend flat planting and amending soil with biochar in saline-sodic acid-sulfate paddy soils in Casamance to improve rice yield. / Master of Science
