The influence of land management on the prevalence of informal settlement and its implication for environmental management in Bahir Dar city, Ethiopia

Dadi, Teshome Taffa 07 1900 (has links)
Bahir Dar is one of the rapidly growing Ethiopian cities characterized by the rise of informal settlements. The expansion of spontaneous neighbourhoods in Bahir Dar is, among other things, conditioned by land management policies and practices. Thus, the intention of this research was to explore the influences of land management on the prevalence of informal settlements in Bahir Dar city, Ethiopia. So as to meet the study targets this research employed mixed method approach, and the data were gathered from various sources by applying different methods. The quantitative data was drawn from 156 random samples through household surveys. It was collected from four FGDs, interview of eight community elders, sub-cities and municipality officials and code enforcement professionals. Furthermore, case studies, published and unpublished documents, photographs, and satellite images were used to enrich the analysis. To analyse quantitative data, SPSS statistical software was used to extract descriptive statistics, to test hypotheses and to draw tables and various types of graphs. Content analysis was employed to analyse qualitative data. It was found that expansion of informal settlements in Bahir Dar was caused, among others, by Poverty of inhabitants, rural-urban migration, limited capacity of the city to deliver basic services, low housing supply and high housing demand, and limitations in land lease laws, as well deficiency of essential amenities like water, sanitation and electricity. The influences of land management policies and practices that resulted to prevalence of informal settlements were found to be the subjective implementation of housing and land leasing policies, harsh government farm expropriation and very low compensation payments, weak governance practices in land administration, frequent demolishing of houses and precarious security of tenure. Even though informal settlements help to address the housing shortage in the city and contribute to environmental management in some areas of the city, it is largely intimidating environmental management, deteriorating the livelihoods and thus brought about the unsustainable city development. In order to address the challenges of informal settlements, it was suggested that legal framework to formalize informal settlements, develop an effective and efficient land administration system, improving good governance in land administration, establish land and housing policies favouring low-income population, and bring about attitude change favourable to urban development are essential. / Environmental Sciences / D.

Policies and regulatory frameworks influencing trends of work-related fatalities and severe injuries in the construction industry in Dar-es-Salaam region, Tanzania, 1980-2009.

Matiko, Joshua Mwita. January 2012 (has links)
Introduction Despite the existence of data in the Labour Commissioner’s Accident and Occupational Diseases Register of Tanzania, trends in the frequency of work-related fatalities and severe injuries in the construction industry, in relation to the development of policies and regulatory frameworks over the years and their effectiveness as interventions, have not been systematically evaluated. Aim The aim of this study was to investigate the relationship between the regulatory framework, trends in the frequency of work-related fatalities and severe injuries among construction workers in Dar-es-Salaam Region, Tanzania, from January 1980 to December 2009. Methods The Accident Notification and Register was accessed from the Tanzanian Labour Department. Data were extracted from the register, coded and analyzed using SPSS. Chi square was used to test if injuries and fatalities in the construction industry and non-construction industries are influenced by introduction of regulatory bodies, legislation and policies during the baseline period (1980 – 1981) and subsequent time periods. Dependent variables were cases of injuries and fatalities in the construction industry and in the non-construction industries, while independent variables included duration during which the regulatory bodies, legislation and policies have been operational, age, sex, education and duration of employment. Results The introduction of regulatory bodies, legislation and policies was statistically significant in the reduction of reported cases in the construction industry across all time periods as compared to the baseline period. The adjusted risk of fatalities and work related injuries frequency in the construction industry decreased (OR 0.5; 95% CI 0.4 – 0.6 during 1998 – 2001) in almost all time periods compared to the baseline period except for the period between 1982 and 1985 (OR 1.2; 95% CI 1.0 to 1.3). Discussion This study is the first to be conducted in Tanzania. The study has shown that new governing bodies and the introduction of new policies and legislations that were introduced in the construction sector were effective in terms of reduction of reported accidents. The results of this study are similar to other studies that have conducted elsewhere. The studies that were conducted in US in 2001and 2003 to evaluate regulatory intervention on vertical falls found evidence that introduction of regulations was effective in preventing non-fatal and fatal injuries in the construction industry. Our results could have been confounded by other factors such as improvement of economic status, construction technologies and work practices. Recommendations In addition to establishment of regulatory bodies, legislation and policies to reduce the accidents, the focus should be also to change technology and practices on construction sites. A safety culture should also be emphasized / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2012.

Conservation of Wild-harvested MedicinalPlant Species in Tanzania : Chain and consequence of commercial trade on medicinal plant species

Nahashon, Michael January 2013 (has links)
Tanzania is endowed with more than 10,000 plant species, of which 1,100 are endemic. The coastal regions host most endemic species, due to its wide range of productive ecological conditions. Over 25 % of all species are used as wild-harvested medicinal plants. About 60% of the Tanzanian population in both rural and urban areas depends on traditional medicine and herbs as their primary health care, and as a means of generating income. This is due to high costs and unavailability of the universal healthcare, which was abolished in 1993. The aim of the thesis is to make a structured and a quantitative investigation to identify traded medicinal plants traded in markets of Dar es Salaam in Tanzania with a purpose to understand the chain and consequences of commercial trade on wild-harvested medicinal plants. A quantitative market research using free list surveys was used in combination with individually repeated in-depth structured and semi-structured interviews. Furthermore, Conservation Assessment and Planning Management method was used to prioritise species that are in need of conservation due to commercial trade. The results show that the chain of commercial trade of medicinal plant species begins in the forest and is then distributed to different stakeholders, such as harvesters, vendors, Traditional Healing Practitioners, consumers and exporters. The research also shows that the large urban and international demand of medicinal plant species supplied by the vendors and exporters is the major threat, specifically to destructively harvested species such as Cassia abbreviata, Zanthoxylum usambarense, Zanthoxylum chalybeum, Myrsine africana, Milicia excelsa and Prunus Africana. These medicinal plants species are up-rooted and/or ring-barked and are therefore in need of conservation. This calls for several conservation guidelines such as policy and regulations, Traditional Ecological Knowledge, education and planting of the medicinal plant species in their natural forests as well as collecting samples of medicinal plant species in a herbarium. Policies can be implemented to conserve these species, for instance only allowing registered practitioners to harvest the medicinal plant species to a level that will sustainably balance the quantity of medicinal plant species in the forest and its supply. In conclusion, an important policy regulation could be an export tax on internationally-traded wild-harvested medicinal that is levied on the purchasing international pharmaceutical companies, which would then be used to fund the conservation of the medicinal plant species to retain a sustainable wild stock. More investigation on the actual population sizes of these plant species is needed in order to secure their existence and contribute to sustainable development both socially and environmentally

Study of a Two-Storey Family House in theDar es Salaam Region, Tanzania / Studie av en tvåvåningsvilla i Dar es Salaamregionen, Tanzania

Svensson, Tina, Ekvall, Emma January 2013 (has links)
This final project is made as a Minor Field Study in Dar es Salaam, Tanzania. Tanzania is one of the poorest countries in the world and this is reflected in the way they live. Many people live in simple houses made out of mud, but the house that have been studied for this final project are a luxurious house from a Tanzanian perspective. The company that builds these houses are National Housing Corporation and it is this company that have provided drawings, information and educational visits. The purpose of this project is to gain knowledge about how a Tanzanian twostorey family house is constructed and designed. The aim is to evaluate if Swedish knowledge in building technique can be implemented to a Tanzanian two-storey family house concerning the climate, building structure and eco friendly construction. To be able to carry through with this final project a Minor Field Study has been executed in Dar es Salaam, Tanzania. During the field study educational visits, interviews and own observations has been made. By studying the drawings, read the interviews and look at photographs that were taken at the site several conclusions have been made. The foundation is the thing that differ the most from a Swedish villa. The slab is cast on underground walls and has only a mould around. Since it does not have a mould underneath the concrete can mix with the limestones and the drainage function is destroyed. The concrete strip that is placed underneath the underground walls has a damp proof membrane underneath which should be placed over the entire foundation structure. The roof is constructed by trusses and rafters in small dimensions. The dimensions could be increased to enlarge the distance between them. The windows are equipped with grilles that should protect from break-ins but also makes it harder to get out in case of fire. The upper slab is merged with the balconies and the balconies do not have an inclination out from the house. This could cause damages on the structure if water is stored there. The walls are made out of concrete which is the best material concerning the climate. To get an even better indoor climate the walls and the rest of the structure could be isolated so energy can be saved when the air conditioner is used. Tanzanian do not think in an eco friendly way but in this question a lot of improvements could be made. From a Swedish perspective there are a lot of things that can be improved on the studied house to get a more sustainable house concerning the structure, climate and eco friendly. / Detta examensarbete har gjorts som en Minor Field Study i Dar es Salaam, Tanzania. Tanzania är ett av de fattigaste länderna i världen och detta återspeglas i deras sätt att bo. Många människor bor i enkla hus gjorda av lera men huset som har studerats för detta examensarbete är ett lyxigt hus sätt ur ett tanzaniskt perspektiv. Företaget som bygger dessa hus är National Housing Corporation och är det bolag som har lämnat ritningar, information och ordnat studiebesök. Syftet med detta projekt är att få kunskap om hur en tanzanisk tvåvåningsvilla byggs och utformas. Målet är att utvärdera om svenska kunskaper i byggnadsteknik kan implementeras på en tanzanisk tvåvåningsvilla med hänseende till konstruktionen, klimatet och miljövänlig konstruktion. För att kunna genomföra detta examensarbete har en Minor Field Study gjorts i Dar es Salaam, Tanzania. Under fältstudien har studiebesök, intervjuer och egna observationer gjorts. Genom att studera ritningar, läsa gjorda intervjuer och titta på fotografier som togs på plats har flera slutsatser gjorts. Grundkonstruktionen är det som skiljer sig mest från en svensk villa. Plattan är gjuten på underjordiska väggar och har bara en gjutform runt om. Eftersom det inte finns någon form under kan betongen blandas med kalkstenen och dräneringsfunktionen kan då förstöras. Betongdelen som är placerad under de underjordiska väggarna har en fuktspärr som också borde placeras över resten av grundkonstruktionen. Taket är konstruerat av takstolar och takbjälkar i små dimensioner. De små dimensionerna resulterar i att takstolarna och takbjälkarna måste sitta tätare än om de skulle ha haft större dimensioner. Fönstren är försedda med galler som ska skydda från inbrott, men de gör det också svårare att komma ut i händelse av brand. Det övre bjälklaget är hopgjutet med balkongerna och balkongerna har inte någon lutning ut från huset. Detta kan orsaka skador på konstruktionen om vatten samlas där. Väggarna är gjorda av betong som är det bästa materialet ur klimatsynpunkt. För att få ännu bättre inomhusklimat kan väggarna och resten av konstruktionen isoleras mot värmen så att energi kan sparas när luftkonditioneringen används. Tanzanier tänker inte på ett miljövänligt sätt, och därför finns det en hel del förbättringar att göra på det här området. Ur ett svenskt perspektiv finns det mycket som kan förbättras på det studerade huset för att få ett mer hållbart hus med hänseende till konstruktionen, klimatet och miljövänlig konstruktion.

Respiratory health of the informal stone crushers in Dar-Es-Salaam.

Kessy, Florian Mathias. January 2010 (has links)
Introduction. Stone crushing in Dar-es-Salaam Tanzania is largely an informal occupational activity, with approximately 7000 workers exposed to varying level of respirable dust. A highly marginalized, self employed, informal stonecrusher is prone to multiple work related risks, particularly dust related respiratory diseases. Aim. This study, the first to be done among informal stone crushers in Southern Africa, aimed at determining the prevalence of dust related respiratory outcomes and relationships between these health endpoints and exposure to respirable dust in this sample of stonecrushers. Methods. This was primarly a cross-sectional descriptive study with analytic components. This study analysed a subset of data collected in a health survey of stone crushers in Kigamboni informal stone quarry in Dar-es-Salaam, Tanzania in 2007. All 200 workers working in the quarry were interviewed. A subset of 86 and 59 workers underwent exposure assessment and health assessments (spirometry and chest radiography) respectively. Associations were investigated between exposure measures and respiratory outcomes. Results. The average age of the workers was 36.3 years with 51.5% males participating in the study. Smoking was common with 30.1% male, 8.25% female smokers, with 2% ex-smokers. Personal dust sampling showed varying dust levels ranging from 0.5-2.8mg/m3 with geometric mean of 1.2gm/m3. The exposure duration of workers in the quarry ranged from 1-62 years with mean of 7.8 years. No single worker was found to use personal protective equipment at work. Reported prevalence of doctor diagnosed respiratory diseases was low: pulmonary tuberculosis (2%), chronic bronchitis (2%), asthma (3%), pneumonia (3%). In contrast, there was high prevalence of respiratory symptoms: chronic cough (13.5%), phlegm production (14.5%), productive cough (10%), wheezing (14%), mild breathlessness (9.5% ) and coughing blood (7.5%). Mean forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) adjusted for age, height and sex was 2.6L/min and 3.7 L respectively, among males and 2.1L/min and 3.0L respectively among females. Adjusted exposure odds ratios for symptoms were statistically significant for mild and moderate breathlessness with odds ratios of 3.4 and 3.1 respectively. Linear regression showed statistically significant decline of 2.3mls in FEV1 with years of exposure while controlling for sex, age, height , doctor diagnosed TB and smoking showing that with prolonged exposure in the quarry, workers are at a risk of developing obstructive lung disease. This trend was not evident for FVC. The majority of films were normal (60.9%), with 19.6% read as 1/0 and 19.9% as 0/1. Discussion. This study identified adverse respiratory outcomes among informal stonecrushers, particularly a high prevalence of respiratory symptoms and clinically important lung function deficits. These are in keeping with other environment studies where workers were exposed to respirable dust. Recommendations. Urgent policy initiatives for developing cost effective hazard control, engineering interventions to protect these marginalized self-employed informal sector stonecrushers are needed. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2010.

The power of expectations : News media confidence among social audiences in Dar es Salaam: An Mfs-study

Hellerud, Emil January 2013 (has links)
In Tanzania, an ongoing private media boom operates within the frameworks of media laws dating back to the 1970s, restricting media freedom and enabling the government to keep some control of what is written on certain topics. This is widely acknowledged and makes Tanzania an interesting subject for studies of news media confidence from an audience perspective. Confidence is viewed as an attitude consisting of three components: the cognitive, the emotive and the behavioral component. The cognitive component consists of expectations and sought gratifications, the emotive component is the feeling of confidence or the disappointment of a failed expectation and the behavioral component includes what media an individual intends to use, which should not be mistaken for what media an individual is actually using. A quantitative questionnaire in Swahili was distributed to 84 randomly selected inhabitants of Dar es Salaam, almost equally distributed between three areas: the lower class area Mwanayamala, the middle class area Kimara and the upper class area Mikocheni. After finishing the quantitative study, 9 qualitative interviews were conducted with a representative selection of those answering the questionnaire. The interviews and questionnaires were conducted during November and December 2013 and all participants were guaranteed anonymity. Finding truthful information, getting education and entertainment was the most frequent sought gratifications from media usage. Media type, language and ownership were the medium characteristics most evidently affecting confidence. Religion, social status and interests were the individual characteristics most evidently affecting confidence. News media confidence turns out to be more about mutual understanding between the individual receiver and the sending medium, than perceived accuracy and independent monitoring of power.

São examinadas as propriedades distribucionais dessa estrutura, em contextos de uso da língua, por meio de critérios formais que levam em conta os aspectos morfossintáticosemânticos, distinguindo-se a estrutura com verbo pleno de verbo suporte e de expressões cristalizadas. As estruturas com verbo suporte são de natureza denominal e deverbal. De modo geral, as denominais denotam ações de golpe como, por exemplo, dar uma pedrada e as deverbais apresentam atenuação e brevidade das ações como, por exemplo, dar uma olhada. Os estudos revelam que as estruturas DAR uma X-ada são também utilizadas como formas modalizadoras da linguagem, constituindo um recurso de expressividade por parte dos falantes nativos.

Made available in DSpace on 2016-08-29T14:09:24Z (GMT). No. of bitstreams: 1 tese_217_.pdf: 710336 bytes, checksum: 6e533b1cf8da5e942187f85defceb70f (MD5) Previous issue date: 2006-02-17 / Esta pesquisa teve como objetivo verificar se os princípios de gestão da Economia de Comunhão, caracterizada por aspectos solidários, humanos e religiosos, são evidenciados na dinâmica de uma organização que adere a esta proposta. Para isso fez-se imprescindível levantar informações sobre este modelo, pouco conhecido no meio acadêmico. O método utilizado para a pesquisa baseou-se na abordagem qualitativa, com ênfase no estudo de caso da empresa FEMAQ S.A., recorrendo-se à entrevista semi-estruturada, à observação e ao levantamento documental como técnicas de coleta dos dados. Para que o objetivo fosse alcançado, no primeiro momento foram diferenciados os conceitos da Economia de Comunhão e Economia Solidária, dado a confusão que por vezes tem ocorrido entre estes dois conceitos que subsidiam diferentes modelos. Em seguida foram abordados os conceitos teóricos fundamentais, sobre os quais a pesquisa foi desenvolvida: valores, valores organizacionais, filosofia (de vida), solidariedade, caráter e dádiva. Na terceira parte foram enfatizados os aspectos da Economia de Comunhão, sua origem, discurso e repercussão. Concluiu-se que as diversas evidências encontradas na empresa estudada, como relacionamento mais humanizado, confiança, ambiente familiar, possibilidade de ser humano (não perfeito) e outros permitem classificá-la no estilo de gestão inerente ao modelo da Economia de Comunhão. / This summary has the objective to check if the main principles of Economy of Sharing Management, which has its most important aspects in solidarity, human and even religious areas, is highlighted by the dynamic reality of an organization which follows this proposal. Therefore we got data about this model still not well known in the academic area. The method used for the research had a qualitative approach emphasizing in the company FEMAQ S.A., using a semi-structured interview technique, observation and document analysis as our sources for data collection. To reach this objective, at first we had to define the difference between the concepts of Solidarity Economy and Economy of Sharing , due to some confusion that has been sometimes been happening between these two models. Afterwards we covered some theoretical basic concepts, about the research developed such as: values, organizational values, philosophy (life), solidarity, character and gift. In a third part we emphasized the aspects of the origin, discourse and repercussion of Economy of Sharing. We came to the conclusion that evidence found in this research, such as a more human relationship, trust, family environment, possibility of the being human (not perfect) and others seem to qualify this company in this style of management, which is characteristic of Economy of Sharing.
