Dr. John Pombe Joseph Magufuli President of the United Republic of Tanzania “Statistics are very vital in the development of any country particularly when they are of good quality since they enable government to understand the needs of its people, set goals and formulate development programmes and monitor their implementation” H.E. Dr. John Pombe Joseph Magufuli the President of the United Republic of Tanzania at the foundation stone-laying ceremony for the new NBS offices in Dodoma December, 2017. What is the importance of statistics in your daily life? “Statistical information is very important as it helps a person to do things in an organizational way with greater precision unlike when one does not have. In my business, for example, statistics help me know where I can get raw materials, get to know the number of my customers and help me prepare products accordingly. Indeed, the numbers show the trend of my business which allows me to predict the future. My customers are both locals and foreigners who yearly visit the region. In June every year, I gather information from various institutions which receive foreign visitors here in Dodoma. With estimated number of visitors in hand, it gives me ample time to prepare products for my clients’ satisfaction. In terms of my daily life, Statistics help me in understanding my daily household needs hence make proper expenditures.” Mr. Kulwa James Zimba, Artist, Sixth street Dodoma.”.

    The United Republic of Tanzania Basic Demographic and Socio-Economic Profile National Bureau of Statistics Ministry of Finance Dar es Salaam and Office of Chief Government Statistician Ministry of State, President ‟s Office, State House and Good Governance Zanzibar April, 2014 UNITED REPUBLIC OF TANZANIA, ADMINISTRATIVE BOUNDARIES Basic Demographic and Socio-Economic Profile Foreword The 2012 Population and Housing Census (PHC) for the United Republic of Tanzania was carried out on the 26th August, 2012. This was the fifth Census after the Union of Tanganyika and Zanzibar in 1964. Other censuses were carried out in 1967, 1978, 1988 and 2002. The 2012 PHC, like previous censuses, will contribute to the improvement of quality of life of Tanzanians through the provision of current and reliable data for policy formulation, development planning and service delivery as well as for monitoring and evaluating national and international development frameworks. The 2012 PHC is unique as the collected information will be used in monitoring and evaluating the Development Vision 2025 for Tanzania Mainland and Zanzibar Development Vision 2020, Five Year Development Plan 2011/12–2015/16, National Strategy for Growth and Reduction of Poverty (NSGRP) commonly known as MKUKUTA and Zanzibar Strategy for Growth and Reduction of Poverty (ZSGRP) commonly known as MKUZA. The Census will also provide information for the evaluation of the Millennium Development Goals (MDGs) in 2015. The Poverty Monitoring Master Plan, which is the monitoring tool for NSGRP and ZSGRP, mapped out core indicators for poverty monitoring against the sequence of surveys, with the 2012 PHC being one of them. Several of these core indicators for poverty monitoring are measured directly from the 2012 PHC.

  • Prevalence of Wuchereria Bancrofti Infection in Mosquitoes from Pangani District, Northeastern Tanzania Godlisten S
    ORIGINAL ARTICLE Prevalence of Wuchereria bancrofti Infection in Mosquitoes from Pangani District, Northeastern Tanzania Godlisten S. Materua aNational Institute for Medical Research, Tukuyu Research Centre, Mbeya, Tanzania Correspondence to Godlisten S. Materu ([email protected]) ABSTRACT Background: Wuchereria bancrofti is the most widely distributed of the 3 nematodes known to cause lymphatic filariasis, the other 2 being Brugia malayi and Brugia timori. Anopheles gambiae and Anopheles funestus are the main vectors. However, the relative contributions of mosquito vectors to disease burden and infectivity are becoming increasingly important in coastal East Africa, and this is particularly true in the urban and semiurban areas of Pangani District, Tanzania. Methods: Mosquitoes were sampled from 5 randomly selected villages of Pangani District, namely, Bweni, Madanga, Meka, Msaraza, and Pangani West. Sampling of mosquitoes was done using standard Centers for Disease Control light traps with incandescent light bulbs. The presence of W. bancrofti in mosquitoes was determined via polymerase chain reaction (PCR) assays using NV1 and NV2 primers, and PoolScreen 2 software was used to determine the estimated rate of W. bancrofti infection in mosquitoes. Results: A total of 951 mosquitoes were collected, of which 99.36% were Culex quinquefasciatus, 0.32% were Anopheles gambiae, and 0.32% other Culex species. The estimated rate of W. bancrofti infection among these mosquitoes was 3.3%. Conclusion: This was the first study employing the use of PoolScreen PCR to detectW. bancrofti circulating in mosquito vectors in Pangani District, northeastern Tanzania. The presence of W. bancrofti infection suggests the possibility of infected humans in the area. The high abundance of Cx.

  • Irrigation of Wetlands in Tanzania
    Irrigation of wetlands in Tanzania Item Type Working Paper Authors Masija, E.H. Download date 06/10/2021 16:30:22 Link to Item http://hdl.handle.net/1834/528 Irrigation of wetlands in Tanzania E.H. Masija Irrigation Department Ministry of Agriculture, Livestock and Cooperatives P.O. Box 9192 Dar es Salaam Summary Over 1,164,000 ha of wetland areas are listed as suitable for irrigation, mainly for crop production and livestock grazing. Existing and planned irrigation schemes are described for the ,main river basins where large areas are devoted to rice and sugar cane. Emphasis' is placed on the value of small scale, farmer-managed irrigation schemes and the rehabilitation of traditional systems. Introduction All wetlands are potentially suitable for agriculture because of their available water and high soil fertility. Due to national priorities or requirements some wetlands are put to other uses, such as game reserves. The total wetland area identified as suitable for irrigation development is estimated to be over 1,164,600 ha (Table 1). Wetlands are swamps or low lying areas of land which are subject to inundation, usually seasonally. They have hydromorphic soils, transitional morphological characteristics between terrestrial and aquatic ecosystems, and support hydrophytes and halophytes. Wetlands in Tanzania can be characterised under four main categories: 1. Deltaic processes of rivers which discharge into the Indian Ocean and are characterised by flat topography, low lying relief and heavy'clay soils. They are subject to sea water intrusion which contributes to the salinisation of the soils which, under predominantly mangrove vegetation, are potentially acid sulphate.

Box 296, Arusha, Tanzania Correspondence should be addressed to Baraka Kichonge; [email protected] Received 7 January 2018; Accepted 8 March 2018; Published 6 May 2018 Academic Editor: Wei-Hsin Chen Copyright © 2018 Baraka Kichonge. Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Tanzania is among the countries with the fastest growing economy in Africa and therefore the need for afordable, clean, and most importantly sustainable electrical energy to meet her ever growing demands is pressing. In recent years, the country’s electricity needs have been largely dominated by thermal generations despite the fact that Tanzania is gifed with huge hydropower resource potential approximated at 38,000 MW with only a very small portion exploited to date. However, the exploited potential is expected to grow by commissioning of identifed large and medium-scale hydropower projects with a total installed capacity of 4,765 MW currently under various stages of implementation. Moreover, the geographical location of Tanzania has several benefts to support development of small hydropower projects essential for appropriate utilization of available water resources as a way of mitigating climate challenges efects. Over the last decade, the country electricity demand along with end-use of energy has witnessed signifcant increases as economic development spreads towards achieving Vision 2025 goals.

Key climate elements like temperature, rainfall and wind speed have been shifting their historical trends and magnitudes over time. As a result, extreme climate and weather driven events such as droughts, prolonged dry periods, erratic rainfall and strong winds are more common across the district nowadays2. The observed climate vagaries coupled with high poverty level have already caused their toll to people, their socio-economic, livelihood and environmental systems. Crop failures, water scarcity and livestock deaths due to drought are already common events in the area. Rainfall seasons and number of rainy days has greatly changed and declined, affecting economic, social, environment and peoples’ livelihoods. Communities are experiencing failures of their traditional livelihood systems with no replacement or alternatives3. Dependence on fishing is also under threat due to catch decrease. As a result, the Poverty and Human Development Report released in 2005 by the United Republic of Tanzania ranked the district as the poorest with the highest rates of income poverty.
