In Burundi, child malnutrition remains a major public health problem, especially among children aged 6 to 59 months. However, data on mothers' nutritional knowledge and practices are still limited, particularly in the Kabezi health district. This study aimed to analyze the factors associated with the nutritional knowledge and practices of mothers with children aged 6 to 59 months in the Kabezi health district. A cross-sectional analytical study was carried out with 403 mothers selected through stratified sampling. Data were collected using a structured questionnaire and then analyzed using both bivariate and multivariate approaches, with estimation of Odds Ratios (OR), Adjusted Odds Ratios (AOR), and 95% confidence intervals. The results reveal an overall insufficient level of nutritional knowledge and practices among the mothers surveyed. Multivariate analysis showed that nutritional knowledge was significantly associated with the mother's occupation, particularly as a trader (OR = 35.48; 95% CI: 1.92–655.40; p = 0.016; AOR = 28.61; 95% CI: 1.75–468.20; p = 0.019), a favorable perception of child feeding (OR = 26.02; 95% CI: 1.57–430.47; p = 0.023; AOR = 21.44; 95% CI: 1.42–320.55; p = 0.027), as well as access to nutrition training (OR = 13.94; 95% CI: 1.38–140.66; p = 0.025; AOR = 11.72; 95% CI: 1.21–112.84; p = 0.031). As for nutritional practices, household food availability (OR = 19.73; 95% CI: 1.44–269.45; p = 0.025; AOR = 16.88; 95% CI: 1.36–210.77; p = 0.028) and the father's salaried job (OR = 10.94; 95% CI: 1.56–76.73; p = 0.016; AOR = 9.41; 95% CI: 1.42–62.35 p = 0,021) were important factors. Sociocultural factors, especially how people view a child's diet, stand out as the most influential determinants of nutritional knowledge and practices (p = 0.001), while socioeconomic factors, particularly food availability, strongly influence the adoption of proper practices. These results highlight the need to strengthen nutrition education programs, improve household food security, and promote access to healthcare services.

This study aims to analyze the nutritional value of Protopterus aethiopicus, a freshwater fish from Lake Tanganyika. Samples were collected from three fishing sites: Karonda, Mvugo, and Magara. The water content, lipid content, fatty acid composition, and mineral content were determined. The analyses were conducted at the laboratory of the Faculty of Sciences at the University of Burundi and at the soil and agri-food analysis laboratory of the Institute of Agricultural Sciences of Burundi (ISABU). Additional samples were analyzed at the laboratory of the International Livestock Research Institute (ILRI) in Kenya for fatty acid profiling. The methods used were Soxhlet extraction and the official AOAC method (2019). The results show that the moisture content of Protopterus aethiopicus is 87.95 ± 5.32%, 68.32 ± 4.75%, and 81.3 ± 1.13% for the Karonda, Mvugo, and Magara sites, respectively. The lipid content is 83.24 ± 2.75%, 99.02 ± 1.11%, and 121.01 ± 1.13%, respectively, which classifies this species among lipid-rich fish. The mineral composition reveals high levels of calcium (54,717 ± 1,396.7 mg/kg), phosphorus (22,357 ± 686.44 mg/kg), and potassium (7,346 ± 151.78 mg/kg). Among trace elements, zinc (142 ± 4.45 mg/kg) and iron (72.40 ± 2.99 mg kg) also exhibit significant concentrations. However, the presence of lead (5.23 ± 0.22 mg/kg) could indicate environmental contamination. The fatty acid profile is dominated by saturated fatty acids (49.07%), followed by monounsaturated fatty acids (34.79%) and polyunsaturated fatty acids (16.12%). Palmitic acid is the most abundant, followed by oleic acid. Fatty acids of nutritional interest, such as linoleic acid, arachidonic acid, and eicosapentaenoic acid (EPA), were also identified. Consumption of Protopterus aethiopicus could thus help improve the nutritional status of local populations and combat malnutrition in Burundi and the Great Lakes region.

This thesis, entitled “Quality Technical and Vocational Education and Training (TVET) in Burundi: Current Situation, Challenges, and Prospects” aimed to analyze the implementation of Burundi’s commitments toward achieving the Sustainable Development Goals (SDGs) related to quality Technical and Vocational Education and Training (TVET) by 2030. More specifically, the study sought to assess the quality of TVET in Burundi through an examination of the organization and functioning of Post-Basic Technical Education Institutions (TEIs) and Vocational Training Centers (VTCs) offering programs in Agro-Food Industry Technologies (AFIT), in light of the SDGs. Using both survey questionnaires and data obtained through document analysis, the findings reveal several challenges affecting education and training in the AFIT field. These include, among others, a lack of adequate materials and equipment necessary to provide young people and adults with the knowledge, skills, and competencies required for work and daily life; the recruitment of personnel without sufficient consideration of professional experience; a shortage of information technology tools that would enable teachers/trainers and students/learners to access learning resources remotely; insufficient public-private partnerships; weak or inadequate cooperation links with comparable international institutions; the lack of effective implementation of a credit transfer and progression system across different TVET training structures. Consequently, the study recommends that all stakeholders fully assume their respective responsibilities. For example, the government is urged to establish and equip boarding Technical Education Institutions and Vocational Training Centers offering AFIT programs, and to provide them with sufficient human, material, and financial resources in both quality and quantity. The government is also encouraged to promote research and innovation related to AFIT in ways that align with global developments. Development partners, for their part, are encouraged to create a support network by investing in partnerships between Burundian Technical Education Institutions and Vocational Training Centers offering AFIT programs and similar institutions in other countries, as well as by facilitating exchange visits and the sharing of experiences.

Access to agricultural credit plays a central role in agricultural development, food security, and poverty reduction in Burundi. However, the Burundian agricultural sector is characterized by major structural constraints, including low mechanization, limited access to inputs, and the financial exclusion of smallholder farmers. In the former Province of Bubanza, where agriculture is the dominant economic activity, access to formal credit remains very limited, hindering the modernization of agricultural farms. This study aims to analyze the determinants of access to agricultural credit in the former Province of Bubanza , addressing the lack of localized empirical data and supporting inclusive financial policies aligned with the Sustainable Development Goals. The analysis is based on data collected from 196 agricultural households in the communes of Mpanda, Rugazi, and Gihanga through a structured questionnaire. Descriptive statistics and a binary Logit model were used for data analysis. The descriptive results reveal a strong reliance on self-financing (92.4%), while access to microfinance institutions remains limited (31.3%). Lack of collateral, high interest rates, and insufficient loan amounts are identified as the main constraints. The econometric results indicate that gender, education level, farm size, membership in farmer groups, proximity to microfinance institutions, and availability of collateral positively influence access to agricultural credit. In contrast, age, marital status, and household size are not statistically significant. These findings highlight the need to strengthen inclusive financial mechanisms tailored to smallholder farmers in the former Province Bubanza.

In Burundi, tea factories are facing a shortage of firewood for drying tea leaves. Deforestation and competition with other uses of wood (such as construction and domestic heating) are exacerbating this problem, pushing factories to seek alternatives to reduce wood consumption. This study conducted in the Tora and Ijenda tea complexes aimed to assess wood use, reforestation efforts, and energy alternatives, in order to identify strategies for the sustainable management of wood resources and to address wood shortage issues. This study uses a mixed approach combining quantitative and qualitative data collection. Data on the quantities of wood used and the areas reforested were collected through semi-structured interviews and factory documents. Data on alternative energy sources were collected through interviews with factory staff and from the literature. The data were synthesized in the form of tables and graphs to facilitate analysis and interpretation. The study showed that over a total of 12 years, the wood consumption of these two factories amounted to 171,175.5 steres, representing an annual average of 14,264 steres. Considering the average per ton of dry tea, for both factories, consumption ranges between 3 to 5 steres of wood with an average of 4 steres per ton of dry tea. Regarding the contribution of own plantations, for the Tora factory, own plantations contribute 42.24% of wood needs, while 57.26% comes from outside. For the Ijenda factory, own plantations contribute 30.4% compared to 69.6% of wood purchased externally. To meet the dry tea production demand planned in the five-year plan of these two factories, projections show that additional reforestation of 659.87 hectares will be required for OTB Ijenda. For OTB Tora, there will be no need to establish new plantations but to convert 57.41 hectares of their own plantations. To reduce excessive wood use, the use of palm kernel shells was tested as a supplement to wood. However, the study showed that, compared to exclusive use of wood steres, their use resulted in an additional economic cost of 21,370 BIF and 39,970 BIF per ton of dry tea for the Ijenda and Tora factories respectively. Although palm kernel shells are a promising alternative, it would therefore be wise to renegotiate prices and explore other strategies to maximize their use. The use of briquettes made from biomass remains a good option to suggest among the various possible alternatives in Burundi, given the abundance of available resources and the relatively easy technological feasibility.
