Content of Iron and Vitamin A in Common Foods Given to Children 12⁻59 Months Old from North Western Tanzania and Central Uganda.

Improving infant and young child feeding is an effective intervention to improve child growth. A cross-sectional study followed by observation of selected households was used to establish the most popular foods given to children 12–59 months old in Bukoba and Kiboga districts of Tanzania and Uganda, respectively. Six meals were identified: maize-based porridge, steamed-mashed banana served with beans, banana cooked with beans, banana cooked with groundnut sauce, stiff porridge (Ugali) served with beans and sardines, and cassava cooked with beans. Raw ingredients were transported to Universität für Bodenkultur, Austria, within 48 h and meals prepared following community validated procedures within 24 h by project team members that involved graduate students from East Africa and Europe. High-performance liquid chromatography (HPLC) analysis and microwave digestion followed by flame atomic absorption spectroscopy were used in establishing provitamin A carotenoids and iron content, respectively. Findings indicated no trace of vitamin A or iron in the maize-based porridge, whereas 2.28 mg/100 g ep (edible portion) and 1.18 mg/100 g ep of iron were recorded in stiff-porridge served with beans and sardines and banana cooked with beans, respectively. Banana-based foods had 23 to 43 vitamin A RAE (retinal activity equivalent) µg/100 g ep. With estimated average requirements of iron and vitamin A for children 1–3 years being 5 mg/day and 275 RAE µg/day, respectively, these foods are poor sources of these nutrients in their current form. Thus, there is a need to explore opportunities for modifying preparation methods and incorporating nutritious and diverse ingredients into the foods prepared for infants and young children in Eastern African countries.

Combining ability, gene action and heritability of weevil resistance, storage root yield and yield related-traits in sweetpotato

The objective of this study was to determine general combining ability (GCA), specific combining ability (SCA), gene action and heritability of weevil (Cylass spp.) resistance, dry matter content (DMC), yield and yield-related components of newly developed sweetpotato clones. Six weevil resistant and six susceptible parents were crossed using a 6 × 6 factorial mating design. The resultant 36 families were evaluated at three locations using a 3 × 12 lattice design with two replications for weevil resistance and yield and related traits in western Tanzania. The GCA effect for females was significant except for percentage marketable root number (PMRN) and percentage marketable root yield (PMRY). Significant GCA effect of males were detected for all traits except PMRY. The SCA effect of families was significant for all traits. With a general predicted ratio (GPR) > 0.5, additive gene action controlled more the expression of total root number (TRN), root yield (RY), DMC, percentage infested root number (PIRN), percentage infested root yield and weevil damage score (WDS), whereas non-additive gene action controlled more the expression of PMRN and PMRY with a < 0.5 GPR. The narrow sense heritability for TRN, RY, DMC, PIRN and WDS were 0.24, 0.56, 0.84, 0.62 and 0.62, while the broad sense heritability for these traits were 0.58, 0.72, 0.93, 0.78 and 0.77, in that order. Four female parents and four male parents were identified as the best general combiners and 13 families recorded the best performance for the evaluated traits. The high heritability for most of the traits studded and presence of both additive and non-additive gene action for the traits suggests that genetic gain can be realized through hybridization and clonal selection in breeding programs. The selected parents and families are useful genetic resources for the development of sweetpotato genotypes resistant to weevils and enhanced root yield, yield components and DMC.

“The Empire Strikes Back”: Communities, Catholic Missions, and Imperial Authority in Western Tanzania, 1934–1960

This article addresses dissent at the time of the encounter between communities and missionaries in Western Tanzania. It centers on the land question and culture as sources of contention between the people and missionaries. It shows that the people’s opposition to eviction from their land and opposition to missionaries’ interference of their culture called for dialogue between the people, missionaries, and imperial authority, and, accordingly, benefitted the parties involved. Using the perspective from below, the article contributes to the scholarship on dissent to show how ordinary peasants responded to the need of missionaries for land and control of the cultural aspects. The article also builds on the idea of ‘long conversation’ from studies on the encounter between communities and missionaries to show how dissent called for mutual discussion between communities, missionaries, and imperial authority.

Society, Conversion, and Frustrations in the CMS and LMS Missions of Unyamwezi, Western Tanzania, 1878-1898

This paper examines conversion strategies and unexpected results in the missions of Church Missionary Society (CMS) and London Missionary Society (LMS) in Unyamwezi, western Tanzania, between 1878 and 1898. Western Tanzania attracted Catholic and Protestant missionaries in the second half of the nineteenth century. Of all the pioneer missionaries, Catholics and Moravians established themselves in the region. Consequently, their education and health institutions received a considerable scholarly attention. Although these missionaries established themselves in the region, the works of the CMS and LMS, notwithstanding the popularity of their medical services and education among the Nyamwezi people, ended in frustration. They subsequently closed their missions after two decades of fruitless missionary work. This paper, therefore, presents this unanticipated outcome of the CMS and LMS missionaries whose conversion strategies had marginal impact on attracting the Nyamwezi people to Christianity. The paper situates the missionaries’ failures within the context of the social world of Unyamwezi, namely indigenous beliefs and practices, slavery, and porterage; these affected evangelisation in the two missions of Urambo Kilimani and Uyui.

Gendered Influence of Artisanal and Small Scale Mining on Primary School Pupils’ Learning Achievements in Western Tanzania

This study explored a critical step towards improving quality of education in ASM area by addressing the problems concerning children’s rights and gendered child rearing. It was guided by the social cognitive theory in explaining the role of environment in moulding children’s behaviour. It measured three objectives: examining the kinds of artisanal and small scale mining activities contribution to development of adjacent primary schools; assessing the influence of artisanal and small scale mining activities on primary school pupils’ learning achievements; and exploring the influence of ASM activities on pupils’ learning achievements by gender. It employed a cross sectional survey design and was conducted in Biharamulo District located Western Tanzania. The respondents were head teachers, primary school teachers, primary school pupils, and ASM leaders, obtained through purposive sampling techniques. Data were collected through observation, interviews, questionnaire, documentary review, and focus group discussion. Data were analysed and presented through tables, figures and thematic analysis. Chisquare test was performed to assess the influence of ASM on pupils’ learning achievement. It was found that the influence of ASM activities on primary school pupils’ learning achievements was significant - X² = 7.133 (1), α = 0.008, with a symmetric measure coefficient (Phi = -.501, α = .003). The negative coefficient value of .50 indicates that ASM activities have large negative effect on pupils learning.Gender-wise, ASM activities affected boys more compared to girls - X² = 5.819 (1), α= 0.016, with a symmetric measure coefficient (Phi = -0.69, α = 0.003).

Sexism in Haya Language Personal Names Selection

This paper examines sexism in naming focussing on the meaning of Haya personal names used in Haya community of North Western Tanzania. It is based on the assumption that some conscious personal names are selected in favour of men. This disparity is well examined by using the Critical Discourse Analysis approach. The paper presents field data from Bukoba Rural district in Kagera Region. The results reveal that meanings of male names were associated with high worthwhile the meanings of female names were associated with low worth. This was justified by the point that Haya male names referred to male as a saviour and helper of the family and society, a strong person, a fighter, a winner, rich and famous person while female names were connected with love, attraction, comfort, soothes and parents disappointment for having a baby girl. The study found that names of female children indicate an important argument that parents considerfemale child as a burden and liability. Generally, it was observed that selection of some Haya personal names was done in discriminatory manner that need an urgent emphasis on the value of names of girls in families and society in general.

Prevalence of HIV infection and uptake of HIV/AIDS services among fisherfolk in landing Islands of Lake Victoria, north western Tanzania

BackgroundNew HIV infections in Tanzania have been decreasing, however some populations remain at higher risk. Despite of that, evidence on the magnitude of HIV infection and the associated factors and HIV/AIDS services uptake among fisherfolk in Tanzania are inadequately explored. This study therefore aimed at determining prevalence of HIV infection and utilization of HIV/AIDS services among fishfolk in selected Islands of Lake Victoria for evidence-based interventions.MethodsCross-sectional study determining status of HIV infection among fisherfolk (n = 456) and retrospective review of voluntary counselling and testing (VCT) registry (n = 1744) were done in Buchosa and Muleba districts. Structured questionnaire and HIV rapid test kits with the standard testing protocol were used as research tools.ResultsA total of 269 (58.9%) male and 187 (41.1%) female fisherfolk were recruited during the community survey. Prevalence of HIV infection was 14% in all surveyed landing sites with a site variation from as low as 7.2% to as high as 23.8%. Participants employed in fishing related employment had higher odds of being HIV infected (5.4 times) than those who practiced fishing and partly farming [OR = 5.40; 95%CI 1.88–15.61; p < 0.001]. Participants employed in fishing related employment had higher odds of being HIV infected (5.4 times) than those practiced fishing and farming [OR = 5.40; 95%CI 1.88–15.61; P < 0.001]. Lack of formal education [aOR = 3.37; 95%CI 1.64–6.92; p < 0.001], being older [aOR = 1.06; 95%CI 1.03–1.09] and using alcohol [aOR = 2.26; 95%CI 1.23–4.15] predicted the likelihood of contracting HIV infection. Approximately three quarters (76%) of respondents had ever tested for HIV infection within past 1 year. Moreover, about half of the study participants had used condom inconsistently and 5 out of 14 (37.5%) of participants who knew their status had never started treatment. Despite the low uptake of most HIV preventive services, majority (88%) of male fisherfolk were circumcised.ConclusionThe magnitude of HIV infection among fisherfolk was up to 3 times higher than that of the general populations in Muleba and Buchosa districts. Higher age, using alcohol and lack of formal education predicted increased likelihood of HIV infection. The uptake of key HIV/AIDS curative and preventive services was generally low.

Family planning and resilience: associations found in a Population, Health, and Environment (PHE) project in Western Tanzania

Using 2016 household survey data from Tanzania, we define and measure resilience within the context of Population, Health, and Environment programming and quantify the link between resilience and family planning. We created a multicomponent model using confirmatory factor analysis in a structural equation modeling context. Factor loadings for eight defined latent factors of resilience were statistically significant (p < 0.001). We created a factor called “FP-MCH” reflecting awareness, attitudes, and access to family planning (FP) and health care services and use of maternal and child health care (MCH) facilities. Analysis, with controls, shows that a 1 standard deviation (SD) increase in FP/MCH was associated with a 0.68 SD increase in resilience (p < 0.01), suggesting that the association between FP/MCH and resilience is robust across a range of factors. Analyses showed that the association between FP/MCH is broadly related to the construct of resilience and not through any single component. This study supports the importance of including FP/MCH as part of integrated projects to enhance resilience.

Leopard (Panthera pardus) predation on a red-tailed monkey (Cercopithecus ascanius) in the Issa Valley, western Tanzania

Predation is predicted to be an important selection pressure for primates. Evidence for this hypothesis is rare, however, due to the scarcity of direct observations of primate predation. We describe an observation of leopard (Panthera pardus) predation on a red-tailed monkey (Cercopithecus ascanius schmidti) at the Issa Valley, a savanna-woodland mosaic landscape in western Tanzania. We compare rates of evidence of leopard presence between Issa and other primate study sites in sub-Saharan Africa. An increase in direct observations of leopards at Issa in recent years suggests that leopards may be habituating to researcher presence.

PO645 Use of Rapid Point of Care Testing For Diagnosis of Group A Strep Throat In Western Tanzania

It is unclear how guidelines panelists discuss and consider factors (criteria) that are formally and not formally included in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. To describe the use of decision criteria, we explored how panelists adhered to GRADE criteria and sought to identify any emerging non-GRADE criteria when the panelists used the Evidence to Decision (EtD) framework as part of GRADE application.We used conventional and summative qualitative analyses to identify themes emerging from face-to-face, panel meeting discussions. Forty-eight members from 12 countries participated in the development of five guidelines for the management of venous thromboembolism by the American Society of Hematology.Ten themes corresponded to the GRADE approach and represented all panel discussions. Over half (53%) of the total panel discussions concerned the use of research evidence. When evidence was considered sufficient and clear, the decision-making process proved rapid.The GRADE EtD framework provides structure to guidelines panel meetings, and ensures that the panelists consider all established formal GRADE criteria as they decide on the recommendation text, strength, and direction (for or against an intervention). This is the first study assessing the use of GRADE's EtD framework during real-time guidelines development using panel discussions. Given the widespread use of GRADE, this study provides important information for practice recommendations generated when guidelines panels explicitly follow, in a transparent and systematic manner, the structured GRADE EtD framework. By recognizing the extent to which panels discuss and consider GRADE and other (non-GRADE) criteria for producing guideline recommendations, we are one step closer to understanding the decision-making process in panels that use a structured framework such as the GRADE EtD framework.

Understanding environmental, health and economic activity interactions following transition of ownership in gold mining areas in Tanzania: A case of private to public

Mining is an important source of revenue for many developing countries, however, the social, environmental and economic impacts of mining are often poorly monitored. The recent transition of a gold mine in Western Tanzania—from large-scale gold mine under private, multinational ownership, to medium-scale public and national owned mine with limited life length offers a prime opportunity to understand the implications of changes in ownership and scale on the local economy and community well-being. We conducted 44 semi-structured interviews with community members in four villages adjacent to the mine site. We find that the local economy and public service provision contracted in response to the mine transition and downscaling, with ramifications for food security and healthcare access. Community members also highlighted the lack of information surrounding the mine transformation. This illustrates that considering the post-transition phase of large-scale mines is important for providing long run sustainable livelihood strategies in mining communities.

Scars on plants sourced for termite fishing tools by chimpanzees: Towards an archaeology of the perishable.

Chimpanzees are well-studied, but raw material acquisition for tool use is still poorly understood as sources are difficult to trace. This study pioneers the use of information that can be gleaned from plant scars made by chimpanzees while they source vegetation parts to manufacture termite fishing tools. Source plant species, raw material types and locations relative to targeted termite mounds were recorded for populations at Gombe, Issa, and Mahale in western Tanzania. Recovered bark, twig, and vine tools were traced to 29 plant species, while grass sources were indeterminable. Bark extraction scars remained detectable for months, and thus possibly for as long as the plant is alive, while twig and vine scars preserved for a few weeks only. Scars preserve better than tools, given that twice as many plant species could be linked to the former than to the latter. Some source species were exploited across all sites for the same type of tool material, while two species were sourced for different types. Compared to apes at Gombe and Mahale, Issa chimpanzees carried material from twice as far away, perhaps because the Issa habitat is more open and dry, which entails greater distances between suitable raw material sources and targeted mounds. Site-specific tools were based on different raw materials, in two cases sourced from the same species, which could suggest learned preferences for particular tool material. "Archaeology of the perishable" as pioneered in this study broadens the methodological approach of the wider field of primate archaeology to include reconstructions of past animal behavior associated with the production of plant based tools.

Temporal patterns of chimpanzee loud calls in the Issa Valley, Tanzania: Evidence of nocturnal acoustic behavior in wild chimpanzees.

Much is known about chimpanzee diurnal call patterns, but far less about night-time vocal behavior. I deployed a passive acoustic monitoring (PAM) system to assess 24-hr temporal acoustic activity of wild, unhabituated chimpanzees that live in a woodland mosaic habitat similar to hominin landscapes from the Plio-Pleistocene. A primary aim was to apply findings to our broader understanding to chimpanzee 24-hr activity patterns, and what implications this may have for reconstructing hominin adaptations to similarly hot, dry, and open landscapes. I also tested whether chimpanzees conform to the acoustic adaptation hypothesis, and produce loud calls during periods of optimal sound transmission. Nine custom-made solar-powered acoustic transmission units (SPATUs) recorded continuously for 250 days over 11 months in the Issa Valley, western Tanzania. I complemented acoustic data with environmental data from weather stations as well as behavioral data collected on chimpanzee nest group sizes to assess the relationship between party size and calling. Chimpanzees called at all hours of the day and night in both wet and dry seasons, and night and day calls exhibited parallel rates/month, although twilight calls were produced significantly more in the dry, compared to the wet season. Calls were more likely during warmer temperatures and lower humidity. Call rate was positively associated with (nest) party size and counter-calls exhibited no temporal variation in their origins (similar vs. adjacent valleys). Chimpanzees were acoustically active throughout the 24-hr cycle, although at low rates compared to diurnal activity, revealing night-time activity in an ape otherwise described as diurnal. Chimpanzee loud calls partially, and weakly, conformed to the acoustic adaptation hypothesis and likely responded to social, rather than environmental factors. Call rates accurately reflect grouping patterns and PAM is demonstrated to be an effective means of remotely assessing activity, especially at times and from places that are difficult to access for researchers.

Efficiency scenarios of charcoal production and consumption – a village case study from Western Tanzania

Availability and access to energy is strongly linked to food security as cooking is needed to make foods ready for consumption. Without access to energy, there is no food security. In rural Tanzania, the population strongly depends on traditional biofuels such as firewood and charcoal. Under the pressure of population growth, energy demand will substantially increase in the next decades. The potential of improved efficiency in charcoal production and efficient cooking stoves were evaluated using scenario analysis. For quantitative data collection, a household survey was conducted in Laela village (2010). The sampling process was based on relative income classes (ICs) defined by local representatives and extending from “rich” (IC 1) to “below self-sufficiency” (IC 4). Based on quantitative survey data, we calculated the quantity of pre-carbonised fuelwood associated with charcoal consumption for ICs in order to display specific consumption patterns. Further, we applied scenario analysis and projected charcoal consumption by 2030 including population growth (+3.41%/year), improved kiln efficiencies (11.1%–20%) and different dissemination rates of efficient stoves (0%–100%). Results of consumption patterns showed that fuelwood consumption in IC 1 was twice that of IC 4, when a conversion efficiency of 11.1% was applied. Calculations of the scenario analyses showed that overall energy consumption will almost double by 2030. The combined approach of a moderate improvement of conversion efficiency (15.6%) combined with a dissemination rate for energy efficient stoves of 50% would overcome the effect of population growth in projected energy consumption and offer a means of coping with future bioenergy demands.

Significance of compositional zoning in cumulate chromites of the Kabanga chonoliths, Tanzania

ABSTRACTCompositional zoning is observed rarely in chrome-spinel grains from slowly-cooled layered intrusions because diffusion of cations continues within the spinel to low temperatures. However, in certain circumstances, such gradational zoning of both divalent and trivalent cations is observed and may be useful in deciphering the thermal history of the host intrusions. The accessory chrome-spinels of the Kabanga mafic-ultramafic chonolith intrusions of the Kibaran igneous event in north western Tanzania are notable because they have preserved gradational compositional zoning. This zoning is demonstrated to predate and be independent of later hydrous alteration of the silicate assemblage. At Kabanga, most chrome-spinel grains within olivine-rich cumulate rocks are gradationally and cryptically zoned from Fe2+-Cr3+ rich cores to more Mg2+-Al3+ rich rims (normal zoning). A few grains are zoned from Mg2+-Al3+ rich cores to more Fe2+-Cr3+ rich rims (reverse zoned). The zoning of divalent cations is proportional to that of trivalent cations with Mg2+ following Al3+ and Fe2+ following Cr3+ from core to rim. The zoning of trivalent and tetravalent cations is interpreted to be caused by either new growth from an evolving melt or peritectic reactions between evolved or contaminated melt and adjacent Al-Cr-bearing ferromagnesian minerals, which is preserved by relatively rapid initial cooling in the small chonolith intrusions. Divalent cation zoning is controlled by sub-solidus exchange of Fe2+ and Mg with adjacent ferromagnesian minerals and continues to lower temperatures, indicated to be 580 to 630°C by the spinel-olivine geothermometer. Preservation of such zoning is more likely in the smaller chonolith intrusions that typically host magmatic nickel-copper sulfide deposits and can be used as an exploration indicator when interpreting chromite compositions in regional heavy indicator mineral surveys.

Assessment of Chimpanzee Nest Detectability in Drone-Acquired Images

As with other species of great apes, chimpanzee numbers have declined over the past decades. Proper conservation of the remaining chimpanzees requires accurate and frequent data on their distribution and density. In Tanzania, 75% of the chimpanzees live at low densities on land outside national parks and little is known about their distribution, density, behavior or ecology. Given the sheer scale of chimpanzee distribution across western Tanzania (&gt;20,000 km2), we need new methods that are time and cost efficient while providing precise and accurate data across broad spatial scales. Scientists have recently demonstrated the usefulness of drones for detecting wildlife, including apes. Whilst direct observation of chimpanzees is unlikely given their elusiveness, we investigated the potential of drones to detect chimpanzee nests in the Issa valley, western Tanzania. Between 2015 and 2016, we tested and compared the capabilities of two fixed-wing drones. We surveyed twenty-two plots (50 × 500 m) in gallery forests and miombo woodlands to compare nest observations from the ground with those from the air. We performed mixed-effects logistic regression models to evaluate the impact of image resolution, seasonality, vegetation type, nest height and color on nest detectability. An average of 10% of the nests spotted from the ground were detected from the air. From the factors tested, only image resolution significantly influenced nest detectability in drone-acquired images. We discuss the potential, but also the limitations, of this technology for determining chimpanzee distribution and density and to provide guidance for future investigations on the use of drones for ape population surveys. Combining traditional and novel technological methods of surveying allows more accurate collection of data on animal distribution and habitat connectivity that has important implications for ape conservation in an increasingly anthropogenically-disturbed landscape.

Attendance of male partners to different reproductive health services in Shinyanga District, North western Tanzania

Background: Male involvement in reproductive health (RH) services in Africa has been associated with improved maternal and child health outcomes. The objective of this study was to determine the prevalence and factors affecting male partner attendance to available reproductive health services in Shinyanga district, north-western Tanzania.Methods: A house to house survey using a structured questionnaire was conducted among randomly selected married men. Additional in-depth interviews were conducted among married men found attending RH services. Factors that motivates the uptake of locally available RH services together with their partners were explored.Results: A total of 204 men participated in the study, 94.4 % (193/204) of them reported to have ever attended the RH service with their female partners at least once whereas 50.6% (103/204) of them attended at least thrice. Three quarters (154/204) attended HIV counselling and testing (VCT) and 63% (129/204) attended antenatal services (ANC). Reported attendance to sexually transmitted infections (STIs/STDs), prevention of HIV transmission from mother to child (PMTCT), and reproductive health cancer services were all less than 13%. The male partners age group (25-34 years; χ2=9.347, df =3 p-value &lt; 0.001), female partner invitation to HR services (χ2= 29.901, df=1, p-value &lt;0.001) and having less than 2 children (χ2= 6.201, df= 2, p-value &lt; 0.05) were associated with higher RH service attendance. Only 20% (4/20) of married men attended RH because they expected better health outcomes in their presence whilst majority attended because they were summoned or just happen to be at the clinic for other purposes.Conclusion: The male attendance to RH services together with their female partners’ in rural Shinyanga was mainly focused ANC and VCT. Most of men attended because were verbally invited by their partners. Education on couple communication empowerment among women attending RH clinics could sustainably improve attendance to all RH services.

DNA recovery from wild chimpanzee tools.

Most of our knowledge of wild chimpanzee behaviour stems from fewer than 10 long-term field sites. This bias limits studies to a potentially unrepresentative set of communities known to show great behavioural diversity on small geographic scales. Here, we introduce a new genetic approach to bridge the gap between behavioural material evidence in unhabituated chimpanzees and genetic advances in the field of primatology. The use of DNA analyses has revolutionised archaeological and primatological fields, whereby extraction of DNA from non-invasively collected samples allows researchers to reconstruct behaviour without ever directly observing individuals. We used commercially available forensic DNA kits to show that termite-fishing by wild chimpanzees (Pan troglodytes schweinfurthii) leaves behind detectable chimpanzee DNA evidence on tools. We then quantified the recovered DNA, compared the yield to that from faecal samples, and performed an initial assessment of mitochondrial and microsatellite markers to identify individuals. From 49 termite-fishing tools from the Issa Valley research site in western Tanzania, we recovered an average of 52 pg/μl chimpanzee DNA, compared to 376.2 pg/μl in faecal DNA extracts. Mitochondrial DNA haplotypes could be assigned to 41 of 49 tools (84%). Twenty-six tool DNA extracts yielded >25 pg/μl DNA and were selected for microsatellite analyses; genotypes were determined with confidence for 18 tools. These tools were used by a minimum of 11 individuals across the study period and termite mounds. These results demonstrate the utility of bio-molecular techniques and a primate archaeology approach in non-invasive monitoring and behavioural reconstruction of unhabituated primate populations.

Land and exile: revisiting the case of Burundian refugees in Tanzania

In 2007, the Government of Tanzania and the Government of Burundi in partnership with the UNHCR adopted the Tanzania Comprehensive Solutions Strategy (TANCOSS). TANCOSS offered a choice between repatriation and naturalization to 220,000 Burundian refugees who had been living in three rural settlements in Western Tanzania (Ulyankulu, Katumba and Mishamo) since 1972. It was an unprecedented intervention and it garnered international attention and support (Milner 2014). Initially, obtaining citizenship was meant to be conditional on relocation away from the refugee settlements. This plan, however, was renounced, and ultimately those who opted for citizenship were permitted to remain on the land of the settlements. Following naturalization, new citizens’ relationship with the land they occupy in Tanzania has changed – both in legal and symbolic terms. This article explores how former Burundian refugees were able to access land in exile and how, following naturalization, they seek recognition of their land rights. In the existing literature, scholars have highlighted the prominence of discourses of autochthony in the ways that both citizenship and land rights have come to be defined and asserted in contexts of migration. There is a risk that this emphasis hides other instances, in which autochthony is not the dominant trope through which citizenship or land rights are claimed, as this article demonstrates in the case of Burundian refugees in Tanzania.
