La dégradation du littoral du lac Tanganyika au Burundi : approche multidisciplinaire
(Bulletin Scientifique sur l’Environnement et la Biodiversité, 2022-08) Ndayishimiye J.,; Ntakimazi G; Nsavyimana G.; Sibomana C.; Mpawenayo B.; Nzigidahera B.; Ndayikeza L.; Vanhove Maarten P.M; Triest L.,; Janssens de Bisthoven L.
A multidisciplinary study analysed the degradation of Lake Tanganyika habitats on the Burundense coast. Several river mouths and the lake shore were sampled near the city of Bujumbura and in the southern part of the country for analysis at several levels: physico-chemistry, diatoms, macrophytes, macro-invertebrates and fish. The results obtained based on these indicators show that the Kanyosha River has a lot of potential in terms of ecological quality, while the Muha and Ntahangwa Rivers seem to be the most polluted. The biodiversity is richer in the South (mostly the tributaries Kamango, Murembwe and Rwaba). In addition to the typology of the sampled sites, the indices show a general degradation of the tributaries of the coastal environment, and to a larger extent in the north of the lake, around Bujumbura. The objective of this study is to alert the scientific community and the decision makers about the progressive degradation of the lake, and to put forward the necessity of setting up a monitoring system on the dynamics of biodiversity and water quality of Lake Tanganyika based on the study of bio-indicators as a basis for decision making and management to mitigate and stop the alarming pollution and degradation of the lake.
Mobilisation des connaissances professionnelles des enseignants dans la préparation et la mise en oeuvre des cours de mathématiques à l’école fondamentale au Burundi
(Formation et profession Revue scientifique internationale en éducation : Volume 29, Number 2, 2021, 2022) Ntwar, Innocent i; Karine Bécu-Robinault
The curriculum reform introduced in Burundi in 2013 in basic school requires for teaching practices to which some teachers were not initially trained. Our study aims to explore how mathematics teachers mobilize their knowledge in their practices. The analysis of interviews with twenty teachers shows that teachers follow tend the cur-riculum requirements. Teachers who have been trained in mathematics education rely on knowledge acquired in initial training while others use their experience in teaching. The teachers’ perceptions of the effectiveness of the training received, in-fluence teaching practices.
La construction de la nouvelle capitale politique du Burundi à Gitega : aménagement urbain, discours sur la ville et « emblématisation »
(Suds, Geographies critiques, perspectives des suds, n° 289, 2024-01) Pasini, Jérémy,; Ngiye, Erasme; Gahungu, Dieudonné
In 2019, Gitega replaced Bujumbura as Burundi's political capital. Against this backdrop, this article examines the ways in which Gitega's urban spaces, and the collective practices and discourses associated with them are being transformed. Our central hypothesis is that, in order to create the new capital, the Burundian state is seeking to distinguish it from other cities by equipping it with modernised infras- tructure and living environments, while at the same time reaffirming its ceremonial functions (process of 'emblematization'). Our study, which is based on an analysis of semi-structured interviews with inhabitants of Gitega (either natives or civil servants relocated to Gitega), institutional sources, and satellite images, shows that Gitega is gradually acquiring the attributes that the government sees as befitting a capital city (high-rise buildings, major facilities, etc.). However, these transformations are also accompanied by social tensions: dirigisme in the urban planning process, opposition, and scepticism from part of the population, and the relegation of the poorest house-holds to the outskirts of the city. In fact, the creation of the new capital is primarily a response to a process of strengthening the State, which wants to demonstrate its ability to manage major projects and stage a sort of revival just a few years after the institutional crisis of 2015.
Modélisation du revenu vital durable et résilience des ménages ruraux pour une sécurité alimentaire et nutritionnelle au Burundi
(UB, ED, 2026-07) Niyonzima, Audace; Sous la direction de Prof. Dr. Ir Niragira Sanctus Prof. Megerle Heidi Elisabeth
Food security and the achieving of a sustainable vital income constitute critical challenges for rural households in Burundi, 84% of whom depend on agriculture vulnerable to climate hazards, low productivity, and land fragmentation. In this context, this doctoral research examines the determinants of sustainable vital income and household resilience in two contrasting livelihood zones : the Northern Depression and the Humid Central Plateaus. It analyzes their socio-economic vulnerability, identi es resilience levers, and proposes an early warning system for food insecurity. The methodology relies on a survey of 384 households, the exploitation of secondary data collected from INSBU and IGEBU, and
quantitative analyses including econometric modeling, household typology, and technical ine ciency estimation.
The results reveal a structural gap between actual income and vital income, the latter being set at 3,242,200 BIF 7/household/year in 2024, while the mean actual income amounts to 2,906,712.87 BIF 8 in the Northern Depression and 2,222,662.50 BIF 9 in the Humid Central Plateaus, yielding a global average of 2,528,074 BIF 10, well below the decency threshold. This generalized precarity is exacerbated by low agricultural productivity, an average technical ine ciency of 29.9%, and recurrent exposure to climate shocks.
Food insecurity is con rmed by mean FIES scores of 2.99 and 3.17, re ecting moderate to severe deprivation. Three typological pro les emerge : a group with relatively high incomes but structural food insecurity, located in the
Northern Depression ; a resilient group, due to food self-su ciency and e ective agricultural diversi cation, located in the Central Plateaus ; a group in chronic food crisis despite a favorable agroecological environment.
The econometric analysis establishes robust causal links between agricultural practices, human capital, and food security. Diversi cation of annual and perennial crops reduces the probability of a poor food consumption score by 5.66%. Each additional cropping season increases the probability of escaping severe insecurity by 1.11%, and a higher education level of the household head increases the probability of an acceptable score by 3.35%.
The adoption of agroforestry, notably the integration of fruit trees and shade species with annual crops, emerges as a resilience strategy, generating an average agricultural income 24.4% higher (2,724,110 BIF 11 vs. 2,189,132 BIF 12) compared to non-agroforestry systems, with a highly signi cant di erence (p = 0.0012). However, the adoption of these sustainable practices remains hindered by limited access to modern inputs for 27% of households in the Northern Depression, 43% in the Central Plateaus, and extreme land fragmentation.
In light of these results, we outline three strategic recommendations : enhance technical e ciency and agricultural productivity via targeted access to modern inputs and the promotion of sustainable agroforestry systems to bridge the ine ciency gap and bring actual incomes closer to the vital threshold ; institutionalize a decentralized Early Warning System integrating validated indicators such as income, FIES, agricultural diversi cation, agroforestry adoption, and climate risks to trigger di erentiated responses based on the three identi ed household pro les ; integrate into public policies a diversi cation of livelihoods, both agricultural like annual crops, perennial crops and agroforestry and non-agricultural like agricultural product processing and commercialisation, demonstrated to signi cantly reduce food insecurity, particularly for households facing land fragmentation, in alignment with the National Development Plan 2018 2027 and the Sustainable Development Goals.
