New Chronology For Neolithic Cultures In The Lake Eyasi Basin, Northern Tanzania, Musa Said Mwitondi, Pastory Magayane Bushozi
Zamani: A Journal of African Historical Studies
There have been several studies on Neolithic Cultures in the Serengeti National. The recovered archaeological materials include domestic and wild fauna remains, potsherds and lithic artefacts, ochre, and stone enclosures, dating between 7200 and 4900 BP. In the East African Rift System (EARS), conventional ages for Neolithic Cultures are inferred from the most extensively researched Neolithic sites in Kenya, where the oldest Nderit ware, cattle and caprine in the Lake Turkana Basin, northern Kenya, date ca. 5200 BP. Studies on the Neolithic of EARS have been structured to fit into the migration or diffusion models that consider the spread of …
Smallpox Outbreaks And Immunization Policies In Tanzania From The Late Nineteenth Century To The First World War, Lorne Larson
Smallpox Outbreaks And Immunization Policies In Tanzania From The Late Nineteenth Century To The First World War, Lorne Larson
Zamani: A Journal of African Historical Studies
An estimated 300 million people died globally from smallpox in the 20th century alone. There was very much a North/South divide in the existence of the disease in that period, with countries across South America, Africa and Asia recording the majority of cases. In 1966 the World Health Organization launched an intensive effort to finally eliminate the disease. The last known endemic case of smallpox was reported in Somalia in 1977, and that outbreak was promptly contained. In 1980 smallpox was declared eradicated – the only infectious disease affecting humans to achieve this distinction. This remains among the most notable …

'Evading The Tax Collector’: Native Responses To The Head Tax In Colonial Njombe, Tanzania, 1920-1960, Peter Chaula, Hezron Kangalawe
Zamani: A Journal of African Historical Studies
Tax collection was one of the core preoccupations of the colonial government in Tanganyika (now Tanzania) and other colonies in the Africa that persisted even after independence. Direct taxation formed the basis of colonial taxation in Tanganyika. Head tax was a dominant form of direct taxation with its burden being borne primarily by Africans. This article uses the colonial Njombe District of Tanganyika to explore the responses of the African taxpayers to the head tax. The available data indicates that colonial head tax policies and practices in Njombe elicited varied responses from Africans with covert forms forming the mainstay of …
Revisiting African Religion As An Academic Discipline In Africa: History And Prospects, Ivan B. Kivinge
Revisiting African Religion As An Academic Discipline In Africa: History And Prospects, Ivan B. Kivinge
Zamani: A Journal of African Historical Studies
Three main religious traditions—indigenous African beliefs and practices (African religion), Christianity and Islam—have dominated everyday life of communities in Africa today. Scholarship on religion indicates that only African religion originated in Africa— Christianity and Islam are foreign religions. Many Africans today have been active Christians and Muslims, who are sometimes being misleadingly taught that African religion is demonic and forms of paganism. This article employs historical and philosophical approaches to show how the study of African religion has navigated through various historical currents and resultant implications on the way the current generation views it. In the end, the article proposes …

Review Of Water Brings No Harm: Management Knowledge And The Struggle For Waters Of Kilimanjaro, Maxmillian J. Chuhila
Review Of Water Brings No Harm: Management Knowledge And The Struggle For Waters Of Kilimanjaro, Maxmillian J. Chuhila
Zamani: A Journal of African Historical Studies
Water Brings No Harm is a key text that enables readers to understand the competing claims to resource control between government authorities and local communities on the ground. Scholarship on the relationship between local knowledge and expert knowledge in resource management and control suggests an asymmetrical relationship in which expert opinion assumes the primary responsibility.1 Bender contrasts traditional and imposed systems of resource ownership and management, arguing that there has been a struggle from both sides, as each side believes it has a rightful claim to ownership and management of water source.
Review Of Decolonising Sociology: An Introduction, Armstrong K. Matogwa
Review Of Decolonising Sociology: An Introduction, Armstrong K. Matogwa
Zamani: A Journal of African Historical Studies
Decolonizing Sociology is one of the few works in sociology that makes critical assessment of the discipline. It is a kind of self-critique within the discipline that aims to reveal epistemic setbacks that have existed for decades. To arrive to the point, Meghji, has situated his thesis along decolonial sociology, which interrogates dominant sociological theories in the context of imperialism. By so doing, he makes three main arguments as follows; first, what is called sociology is colonial in nature as it is based on the ideas of the Western thinkers namely Marx, Durkheim and Weber which emerged and institutionalized during …

The Quest For The Survival And Influence Of Business Associations In A Turbulent Environment: Lessons From Tanzania, Goodluck Charles, Donath Olomi
Business Management Review
This article investigates the driving force of business associations (BAs) in their attempt to influence policy regarding political and economic governance in Tanzania. On the basis of the collective action theory, new institutional economics (NIE) and historical analysis of 21 BAs, it is evident that they are driven by the evolutionary extensions of international ecosystem capabilities, the ability of BAs' leadership to change with the government agenda, the political ideology and their experience and competence to dialogue with the government. The article contributes to the collective action theory and the NIE literature by demonstrating that BAs take collective action to …
Assessing The Potential For Tanzanian Exports In The African Continental Free Trade Area, Mesia Ilomo
Assessing The Potential For Tanzanian Exports In The African Continental Free Trade Area, Mesia Ilomo
Business Management Review
In 2019, the Africa Union launched the African Continental Free Trade Area (AfCFTA), one of the largest pro-development regional trade arrangements (RTAs) in the world. Despite the broad promises, the potential trade benefits of AfCFTA to specific African countries is not crystal clear. We employ a gravity model and the Pseudo Poisson Maximum Likelihood (PPML) estimator to establish the existence, magnitude, and change of Tanzania export potential in 49 African markets. The results show existence of export potential in 38 markets, and inexistence of export potential in 11 markets. Out of 38 markets with export potential, Tanzania has high export …
Legal Provisions And Administration Of Land Disputes In Kiteto District, Ca. 1970s – 2000s: The Missing Linkage, Juma Marmo
Zamani: A Journal of African Historical Studies
There have been a series of legal interventions on land use in the post-colonial Tanzania to create a good land administration and management in order to end land use conflicts. Scholarship on the legal aspect of land use indicates that legal interventions did not provide lasting solutions to land use conflicts because of their structural and systemic arrangements. In addition, existing scholarship has little focus on the linkage between law enforcement machinery, the peoples’ level of understanding on land laws, and the occurrence of land use conflicts. This paper discusses the violation of laws by peasants, pastoralists, and government officials …

Finite Element Models For Predicting Moisture Effects On Bolt Embedment And Connection In Timber, Henry Meleki Kiwelu
Tanzania Journal of Science
The mechanical performances of timber connections are particularly important for timber engineers involved in the design of the wood structures. The mechanism of connection must be well understood in order to design a safer connection and avoid catastrophic failure. Often connections are made weak fuse elements by deliberate intent to ensure that if structural systems fail it will be by controllable ductile deformation of connections in load paths. Model method of determining engineering design capacities of laterally loaded dowel fasteners, such as bolts, screws and nails was developed. It should however be pointed out that FE and similar continuum model …
