  • Geographic Distribution of Indigenous Rice-Cultivation Techniques and Their Expansion in Tanzania
    Trop. Agr. Develop. 63（1）：18 － 26，2019 Geographic Distribution of Indigenous Rice-cultivation Techniques and Their Expansion in Tanzania Futoshi KATO* College of Bioresource Sciences, Nihon University, 1866 Kameino, Fujisawa, Kanagawa 252-0880, Japan Abstract In Tanzania, indigenous rice-cultivation productivity is generally lower than that of rice cultivation using modern irrigation systems, even though it is a nationwide practice. Practical improvements in indigenous rice cultivation are required to increase the productivity, stability, and sustainability of rice cultivation. Tanzania is a major rice-producing country in Africa and the demand for rice is continuously increasing; therefore, indigenous rice cultivation has also increased for more than 20 years. This study was focused on indigenous rice cultivation and aimed at elucidating the geographic distribution of indigenous rice cultivation and characterizing the techniques used. Fieldwork was conducted in Mwanza, Shinyanga, Tabora, Mbeya, Dodoma, Rukwa, Morogoro, and Dar es Salaam, which are the major rice-producing areas in Tanzania. Two basic rice-cultivation techniques are used in that country; one utilizes runoff from rainfall and the other uses floodwater from streams, rivers, and swamps. The former is practiced in northern and western Tanzania and is characterized by transplanting, building levees, and plowing with bullocks, while the latter is practiced in south-central Tanzania and is characterized by broadcasting seed, irrigating with floodwater, and using tractors. Furthermore, rice cultivation that utilizes runoff expanded from northern to southern regions of Tanzania in parallel with the migration of the Sukuma people; this has increased the diversification of Tanzanian rice cultivation. These indigenous rice-cultivation techniques were found to be affected by geographical, meteorological, and social conditions.

  • Tanzania 2016 International Religious Freedom Report
    TANZANIA 2016 INTERNATIONAL RELIGIOUS FREEDOM REPORT Executive Summary The constitutions of the union government and of the semiautonomous government in Zanzibar both prohibit religious discrimination and provide for freedom of religious choice. Three individuals were convicted and sentenced to life imprisonment for the arson of a church in Kagera. A Christian bishop in Dar es Salaam was arrested and accused of sedition for speaking on political matters from the pulpit. The church’s license was withheld while police continued to investigate at year’s end. The president and prime minister, along with local government officials, emphasized peace and religious tolerance through dialogue with religious leaders. Prime Minister Kassim Majaliwa addressed an interfaith iftar in July, noting his appreciation for religious leaders using their place of worship to preach tolerance, peace, and harmony. In May 15 masked assailants bombarded and attacked individuals at the Rahmani Mosque, killing three people, including the imam, and injuring several others. Arsonists set fire to three churches within four months in the Kagera Region, where church burning has been a recurring concern of religious leaders. The police had not arrested any suspects by the end of the year. Civil society groups continued to promote peaceful interactions and religious tolerance. The U.S. embassy began implementing a program to counter violent extremism narratives and strengthen the framework for religious tolerance. A Department of State official visited the country to participate in a conference of Anglican leaders on issues of religious freedom and relations between Christians and Muslims. Embassy officers continued to advocate for religious peace and tolerance in meetings with religious leaders in Zanzibar.

Received: 27 November 2013; in revised form: 27 January 2014 / Accepted: 12 February 2014 / Published: 20 February 2014 Abstract: REDD+ has been proposed as a viable option for addressing climate change in the near term, and at relatively low cost. There is a broad consensus that clearly defined tenure rights are important for the implementation and success of REDD+, both to manage forests effectively and to protect local communities’ livelihoods. We use primary data from 23 villages in six REDD+ pilot sites in Tanzania to identify causes of deforestation and forest degradation, and tenure rights issues, at the village level prior to project implementation. Further, interviews with project proponents and examination of project documents yields insights into how the proponents plan to address tenure issues.

A. Kulindwa Economic Research Bureau, University of Dar es Salaam, P.O. Box 35096 Dar es Salaam, Tanzania Email: [email protected] ABSTRACT Discussions on social and policy dimensions of the Lake Victoria Basin (LVB) centre on the inhabitants of the basin and their livelihood strategies which are defined by environmental stewardship and natural resource utilization. This paper presents a contextual narrative of the people of the LVB and their livelihood. It sets the stage for an ecosystem assessment of the basin’s social and economic implication of natural resource state, trends and vulnerabilities. The demographic characteristics and selected social indicators for the basin are presented with a focus on implications to sustainable resource management. A description of fishing together with other main occupational activities of the basin’s inhabitants is presented with emphasis on strategies, impacts, challenges and vulnerabilities that the current resources extraction activities impose on the people and environment. Owing to the transboundary nature of the basin, it is recognised that the people and institutional framework of the basin including the East African Community (EAC) together with subsidiary arrangements such as the Lake Victoria Development Programme (LVDP) hold the key to a joint and sustainable management of the basin.

  • Tanzania Page 1 of 21
    Tanzania Page 1 of 21 Tanzania Country Reports on Human Rights Practices - 2007 Released by the Bureau of Democracy, Human Rights, and Labor March 11, 2008 The United Republic of Tanzania, with a population of approximately 39.3 million, is a multiparty republic consisting of the mainland and the Zanzibar archipelago. The union is headed by a president, who is also head of government, and its unicameral legislative body is the National Assembly (parliament). Zanzibar, although integrated into the country's governmental and party structure, has its own president, court system, and legislature, and continued to exercise considerable autonomy. In the 2005 union presidential and legislative elections, Jakaya Kikwete was elected president, and the ruling Chama Cha Mapinduzi (CCM) Party made significant gains in parliament. Observers considered the union elections on both the mainland and in Zanzibar to be largely free and fair. However, the 2005 presidential elections for president of Zanzibar were more contentious, with serious irregularities and politically motivated violence. While civilian authorities generally maintained effective control of the security forces, there were isolated instances in which elements of the security forces acted independently of government authority. There were a number of continuing human rights problems. Police and prison guards used excessive force against inmates or suspects, at times resulting in death, and police impunity was a problem; there were continued reports of killings of elderly individuals accused of being witches; prison conditions were harsh and life-threatening; there was widespread police corruption and violation of legal procedures; the judiciary suffered from corruption and inefficiency, especially in the lower courts; freedom of speech and press were partly limited; governmental corruption remained pervasive; authorities restricted the movement of refugees; societal violence against women persisted; and trafficking in persons and child labor were problems.

  • Tanzania Joint Annual Report 2008
    TANZANIA JOINT ANNUAL REPORT 2008 EXECUTIVE SUMMARY In 2008 the political situation in Tanzania was relatively stable. Two by-elections were conducted in a largely peaceful manner. Both seats were won by the parties which held them originally, the ruling CCM and the opposition CHADEMA. Key feature was the battle against corruption. Following an audit of the External Payment Account of the Bank of Tanzania (BoT), which indicated fraudulent transactions and serious shortcomings in the controls within the BoT led President Kikwete to create a High Level Task Force that resulted in the arrests of the prominent businessmen and BoT senior staff. They are facing charges ranging from forgery to theft. In February, an investigation and a critical report by the Parliament on the questionable procurement of a 1000MW generator (the Richmond case) led to the resignation of Prime Minister Lowassa and to the dissolution of the cabinet. Other high profile businessmen, civil servants and politicians were arrested on corruption allegations towards the end of the year. The list included the National Authorising Officer and the Permanent Secretary of the Ministry of Finance. The persistent active participation of the Opposition political parties and civil society, in particular the media played an important role in exposing and fighting corruption. The economic evolution witnessed a good performance despite the turbulent external environment. Economic growth reached 7.5%, but inflation broke into double digits in September (13.5%) as a result of the rise in global food and fuel prices, reaching its highest level in a decade. According to the IMF, Tanzania’s 2008/2009 current account deficit increased by 1.9% points to 9.7% of GDP as a result of food price increases, while foreign reserves decreased from 3.2 to 2.5 months of imports.

  • Impact of Livestock Grazing to Fringing Wetlands of Lake Victoria (Tanzania Experience)
    Impact of Livestock Grazing to Fringing Wetlands of Lake Victoria (Tanzania Experience) M. Maskini and H. Hongo Wetland Management Component P.O.Box 11045, Mwanza-Tanzania Tel/Fax:255 282 500806 Tel: 255 282 550445 EMAIL: [email protected] Abstract A baseline study was carried out in October/November 1999 to assess the impacts of Livestock grazing on the fringing wetlands of Lake Victoria on the Tanzanian side. Two villages bordering the Western Corridor of the Serengeti National Park in the east and Lake Victoria in the west were selected. Lamadi and Mbalageti rivers drain them. The flood plains are utilized for livestock grazing and as a refuge of wild game during the dry season. The area has been experiencing a high influx of immigrant pastoral herds from Shinyanga region, which has resulted, into serious land degradations. Range conditions at Lamadi were rated fair with retrogressing range trend. The carrying capacity was estimated at 3.57 to 6.75 ha/LU, which were 5 overstocked. Range condition at Nyatwali was rated good and the dry season carrying capacity was estimated at 1.5 ha/LU. Immigrant pastoral herds in the study area accounted for 79% and 82% of the total herds at Nyatwali and Lamadi, respectively. Keywords: Lake Victoria; Overgrazing; Wetlands; Degradation Introduction Wetland is a term used for large variety of ecosystems which have one thing in common; the presence of both land and water for most part of the year. In Africa wetlands cover an area of about 250,000 km2, which represents about 1% of the total continental area and in Tanzania almost 10% of the country’s surface area is covered by wetlands (NEMC/WWF/ICUN, 1990).
