Household Food Security Among Hadza Hunter-Gatherers In Safari et al. Agric & Food Secur (2021) 10:20 https://doi.org/10.1186/s40066-021-00293-x Agriculture & Food Security RESEARCH Open Access Household food security among Hadza hunter-gatherers in Mkalama district, Tanzania John Godfrey Safari1* , Aron Joseph Nkua2 and Zacharia Samwel Masanyiwa2 Abstract Background: Food insecurity is a widespread public health concern in many communities of sub-Saharan Africa. This study involved the Hadza hunter-gatherers of Tanzania, the only ethnic group in the country that has traditionally sub- sisted on hunting and gathering. In recent years, however, these communities have adopted mixed foraging economies. Information on how this change afects household food security is rather limited. The aim of this study was to assess the status of food security and the factors infuencing household food security in the Hadza hunter-gatherer communities. Methods: A cross-sectional study of 200 households was conducted in Mkalama district, Tanzania. Sampled house- holders represented individuals whose livelihood is mainly dependent on foraging (n 129), beekeeping (n 30) and farming (n 41). Food security was measured by assessing food availability (Months of= Adequate Food Provisioning= (MAHFP)), food= access (Household Food Insecurity Access Scale (HFIAS)) and food utilization (Dietary Diversity Scores (DDS)). Results: Mean MAHFP was lower (p 0.000) in predominantly foraging households (8.4 1.1) compared with those involved in beekeeping (8.7 1.6) or =farming (9.6 1.9). Based on HFIAS indicator, the prevalence± of food insecurity varied with the household’s ±main activity (83.0% foraging,± 46.7% beekeeping and 26.8% farming). Further, regres- sion analyses show that the farming households were more likely to be food secure than the foraging households (OR 10.7, p 0.01). Dietary diversity scores also varied signifcantly with household’s main activity. About 65% of households= (86%= foraging, 63.3% beekeeping and 2.4% farming) consumed diets below the critical value of 4 food groups 24 h prior to survey. Social demographic characteristics and livelihood options are strong predictors of≤ house- hold food security. Conclusion: All indicators used to assess food security point to high level of food insecurity in households mainly subsisting on foraging compared with beekeeping and farming. The primary dependence on foraging is associated with a longer period of food shortage, high prevalence of food insecurity conditions and low consumption of food varieties. Livelihood diversifcation coupled with provision of agricultural support services is necessary for the devel- opment of a secure future of the Hadza communities.

Journal of Physiological Anthropology (2018) 37:10 https://doi.org/10.1186/s40101-018-0171-0 ORIGINALARTICLE Open Access Serotonergic gene polymorphisms (5- HTTLPR,5HTR1A,5HTR2A), and population differences in aggression: traditional (Hadza and Datoga) and industrial (Russians) populations compared Marina L. Butovskaya1,2,3*, Polina R. Butovskaya4, Vasiliy A. Vasilyev5, Jane M. Sukhodolskaya5, Dania I. Fekhredtinova5, Dmitri V. Karelin6, Julia N. Fedenok1, Audax Z. P. Mabulla7, Alexey P. Ryskov5 and Oleg E. Lazebny8 Abstract Background: Current knowledge on genetic basis of aggressive behavior is still contradictory. This may be due to the fact that the majority of studies targeting associations between candidate genes and aggression are conducted on industrial societies and mainly dealing with various types of psychopathology and disorders. Because of that, our study was carried on healthy adult individuals of both sex (n = 853). Methods: Three populations were examined: two traditional (Hadza and Datoga) and one industrial (Russians), and the association of aggression with the following polymorphisms 5-HTTLPR, rs6295 (5HTR1A gene), and rs6311 (5HTR2A gene) were tested. Aggression was measured as total self-ratings on Buss-Perry Aggression Questionnaire. Results: Distributions of allelic frequencies of 5-HTTLPR and 5HTR1A polymorphisms were significantly different among the three populations. Consequently, the association analyses for these two candidate genes were carried out separately for each population, while for the 5HTR2A polymorphism, it was conducted on the pooled data that made possible to introduce ethnic factor in the ANOVA model. The traditional biometrical approach revealed no sex differences in total aggression in all three samples. The three-way ANOVA (μ + 5-HTTLPR +5HTR1A +5HTR2A +ε) with measures of self-reported total aggression as dependent variable revealed significant effect of the second serotonin receptor gene polymorphism for the Hadza sample.

History may also be defined as a branch of knowledge which deals with past events of human beings and their response to their environment over the years.R.G Collingwood, in his book The Idea of History (OUP 1994) defined history as a “science concerned with the human actions in the past, pursued by interpretation of evidence for the sake of Human self knowledge.” That history is a science because it involves finding out things about the past Humankind. For example, the origin of Man, why he was a toolmaker, why he domesticated animals and plants. These are questions that provoke scientific curiosity. The three definitions of History from the above are: History is the past of anything; of earth, man, disease or animals History is a branch of knowledge dealing with past events History is a science concerned with past Human actions Since History at secondary level is specifically concerned with the past as it relates to humankind and his response to his environment over the years, the working definition of history is therefore; History is the endless story of mankind’s actions and events affecting him in the past.

The pipeline will run from Kabaale in Hoima District, Uganda, to a Marine Storage Terminal (MST) at Chongoleani, Tanga Region, in Tanzania, on the East African coast. The length of the pipeline is 1,450 kilometres (km), of which approximately 1,147 km will be in Tanzania. The pipeline will cross from Uganda to Tanzania at the border town of Mutukula. The pipeline will traverse eight regions and 25 districts in Tanzania.
