Despite its potential in supporting people’s livelihood in Babati, Lake Babati is being converted into other land uses due to ever increasing population in town. This work evaluates the impacts of population increase around Lake Babati in Babati Town Council. Primary data were gathered by administering the questionnaire to a sample of 100 households. Participatory rural appraisal techniques, participant observation and checklist were employed in data collection. The land use types and land use changes was examined through analysis of satellite imageries. This was attained by making use of ArcGIS10. The results from the present study showed that there was a strong relationship (p≤0.05) between education level, occupation and awareness status of respondent on environmental issues. Also there was a strong association between the anthropogenic activities in particular agriculture/brick making and lake degradation. Lack of awareness under the role of environmental sustainability on lake resources was found to hinder the involvement of local people to Lake Babati conservation. Thus, this study recommends that, natural resources management (including lakes) should be incorporated in the program of study of all education levels to foster awareness raising campaign on role of lake benefits to local people’s livelihoods. Also proper land use practices should be promoted so as to reduce the impacts that has been caused on the lake Babati due to poor land use practices in the study area. viii TABLE OF CONTENT

Significant high grade gold mineralisation encountered at surface at Winston. High grade gold results from pit sampling include: - 3m @ 36.80g/t Gold from surface - 3m @ 21.54g/t Gold from surface - 2.6m @ 14.65g/t Gold from surface - 0.1m @ 23.88g/t Gold from 2m . High grade gold results from trench sampling include: - 13m @ 0.72g/t Gold incl. 2m @ 2.40g/t Gold - 2m @ 0.92g/t Gold . Trench results indicate significant mineralisation at the Mjuhu Target, where a strong IP chargeability target exists at depth >150m and has had very limited drilling to date (one hole) returned 5m @ 1.34g/t Gold from 83m 1. Peak grab sample at Winston assayed at 81.0 g/t Gold. These latest pit results confirm that high grade gold mineralisation continues to surface above the northern shoot at Winston, where previous drilling returned significant ore grade intercepts including 1: - 16m @ 55.23g/t Gold from 116m - 14m @ 13.33g/t Gold from 133m - 7m @ 35.89g/t Gold from 123m .

E-mail: [email protected] Abstract In this paper, we revisit the on-the-ground reality of Burunge Wildlife Management Area (WMA) that is celebrated as one of Tanzania’s best examples of community-based conservation (CBC). We find Burunge WMA rife with conflict and contestation over grievances that remained unsettled since its establishment a decade ago. These grievances have been accentuated by growing land pressure resulting from increasing human, livestock, and elephant populations, in combination with infrastructure improvements and support for agriculture-led development. The WMA governance regime has little to offer the residents and village leaders of Burunge member villages who appear hostages in a situation where interests in human development and conservation are pitted against each other, making a mockery of the notions of CBC. By re-examining this exemplary WMA case and compare our findings with the way it is being portrayed by supporting agencies, we pinpoint the tendency of the actors promoting conservation in Tanzania to misrepresent or ignore the realities on the ground that defy official policy promises.

  • Rural–Urban Migration in the Context of Babati Town
    Södertörn University College | School of Life Sciences Bachelor’s Thesis 15 ECTS | Global Development | Spring term 2008 RURAL–URBAN MIGRATION IN THE CONTEXT OF BABATI TOWN, TANZANIA – CAUSES AND EFFECTS ON POOR PEOPLES’ QUALITY OF LIFE By: Johan Magnér Supervisor: Adolphine Kateka ABSTRACT The objective of this research is to study peoples’ reasons for rural-urban migration in the Babati district of Tanzania and the outcomes of such a migration on the migrants’ quality of life in Babati town. This qualitative study is based on semi-structured interviews and secondary sources. The interviews were performed with poor people in urban Babati town and two villages in rural Babati district. In the last thirty years the population of Babati town has increased more than threefold. The causes of rural-urban migration to Babati town are to be found in economical, social and cultural factors. The economic predominate, with the search for employment mentioned by all the migrants in the study. The migrants in Babati town emphasized adequate housing as a very important factor for a good life in town. This need was in many cases not fulfilled. Many were also still lacking social services and could not afford to buy basic necessities. The greatest asset for the people who have moved to Babati town was the diverse market of employment. The benefits of living in Babati town seem to outnumber the problems for most of the urban migrants. For the villagers of Mutuka the greatest asset was good natural conditions for agriculture and lifestock. In Magugu a great advantage was trade, the affordability of houses, food and necessary things.

  • Have the Tsetse Clearings in the Babati District, Tanzania, Influenced the Spread of Agri- Culture Land?
    Södertörns högskola | Institutionen för Livsvetenskaper Kandidatuppsats 15 hp | Miljövetenskap | Vårterminen 2009 Programmet för Miljö och utveckling Have the Tsetse Clearings in the Babati District, Tanzania, Influenced the Spread of Agri- culture Land? Av: Annika Burström Handledare: Kari Lehtilä Abstract The clearing of woodland to eradicate the tsetse fly in the Babati district, Tanzania, was a governmental initiative. The clearings were mainly carried out in the mid 20th century and managed to reduce the tsetse fly by a great amount. The clearings opened up remote areas and made it possible to access areas that had previously been unavailable for humans. The clear- ing also had an enormous impact on the environment. This is a case study on five different areas in the Babati district that have all been subjected to tsetse clearings. The studied areas are Bonga, Kiru Erri Kiru Valley, Magugu and Mamire. The fieldwork consisted of semi-structured interviews and transect walks. The purpose was to study if the clearings have had any influence over the spreading of agriculture land that were not cultivated before and to inquire into the most significant environmental impact that the clearings had. Different outcome in agriculture land spreading due to the clearings could be seen in the five studied areas. In Bonga and Kiru Valley no agriculture started after the clearings, but in Kiru Erri, Magugu and Mamire some of cleared land is nowadays used for agriculture. The result of the fieldwork indicates that the clearings have had noticeable influence over the spreading of agriculture land but there were also other important driving forces.
