An exploration of the prevailing perceptions on the role and skills of environmental health officers regarding the prevention of Cholera outbreaks in Lusaka districtChibiya, Hilary M.S. January 2009 (has links)
Master of Public Health - MPH / Background:cholera outbreaks have almost become a norm in Lusaka district with the onset of rains.The disease forms part of the preventable diarrhea diseases that have greatly contributed to the high morbidity and mortality rates especially in children under five. In an effort to mitigate the recurrence of cholera in the district of Lusaka, various strategies have been employed to resolve the crisis. However none have investigated the skill or capacity of the public health officers involved in health promotion and disease prevention,themselves. Therefore in this study, focus is turned on one of the integral officers in this public health arena who seem directly involved in preventive health, the Environmental Health Officers. The aim is to clarify their role and skills capacity with the hope of initiating a process of developing appropriate skills and therefore positively contribute to
the fight to contain cholera outbreaks.Study Design:this is mainly a qualitative descriptive study that seeks to gain insight into the problem
EHOs in Lusaka may be facing in averting cholera outbreaks by exploring in-depth, their attitudes, beliefs and values concerning their role and capacity with consideration to the training they receive to prepare them for their role. The sample was drawn from the EHO’s from 26 health centers under the jurisdiction of the Lusaka Urban District Health Management Team (LUDHMT).Data Collection:data was collected from the EHOs through focus group discussions to scrutinize how their knowledge and experience interact in their setting. Consequently, a few follow-up EHO interviews were done for further clarification of recorded data. Face to face, semistructured interviews were conducted with their supervisors as well as EHO trainers from the two local colleges concerned with EHO training.
UWC, SOPH, mini-thesis, Hilary Chibiya, 2520505.May 2009 Analysis of Results:a qualitative approach to data analysis was employed which commenced during data collection through member checking to comparing, coding, categorizing and seeking meaningful interpretations of emerging themes.Discussion and Conclusion:while the EHOs’ perceive themselves essentially as promoters of environmental health,this study discovered that they dwell more on control measures in the matter of cholera out breaks. Even though they feel confident to contain an outbreak they expressed a lack in the level of skills they possessed to enable them to monitor, evaluate and consequently get rid of the all the factors that cause the disease to recur. Inevitably with this lack of self-assurance to eradicate cholera they seem resolved to focusing their resources to adequately prepare for the control of cholera than its prevention, instead. Very importantly, it was found that both policy development and training are to lagging behind the demands of the EHOs current role and their work is hindered by lack of funds specific to prevention activities complicated by an unhealthy donor dependency. There also is a need for all the key players in the environmental Health arena to appreciate the shift in the role of an EHO from the former traditional responsibilities because the incidence of
cholera could keep recurring unless all these stakeholders could join forces in training and supporting the EHO appropriately.UWC, SOPH, mini-thesis, Hilary Chibiya, 2520505.May 2009

Ecological Sanitation : Attitudes Towards Urine Diverting Toilets and Reuse of Nutrients in Peri Urban Areas of Kampala, Uganda. A Case of Kamworkya II ParishMinze Ngobi, Richard January 2007 (has links)
<p>ABSTRACT</p><p>Billions of people are living without access to safe hygienic means of personal sanitation. The sanitation gap is wide in developing countries where more people are increasingly becoming urbanised. Sanitation related diseases are some of the leading cause of mortality and morbidity among the population in developing countries especially children under age of 5 years. The responsible institutions are faced with challenge to provide suitable and affordable services to this increasing population. In Uganda, the urban poor are residing in the peri urban areas with inadequate sanitation facilities. The provision of conventional sanitation facilities are seen not be sustainable options due to contamination of both surface and underground water sources, congested housing structure and at the same time makes recycling and reuse of nutrients difficult.</p><p>This study investigated attitudes towards urine diverting toilets in one of the peri urban areas in Kampala, with the aim of finding out strategies to improve on awareness of ecological sanitation as well as popularise their use as alternative sanitation. Respondents’ views were collected through face to face interviews with 40 household respondents using a semi structured questionnaire and field observations of the household’s toilet in use as well as solid waste disposal. Four focus group discussions and 6 key informant interviews were also performed.</p><p>The respondents’ acceptance of the urine diverting toilets was relatively positive. Most of the respondents reported that the ecosan toilets are a viable option due to congested housing pattern, desire to own a toilet (for those who never had a toilet before), improved privacy, and convenience among other factors. Respondents who have no urine diverting toilets also preferred urine diverting toilets and expressed their willingness to replicate them. It was also found that residents in Kamwokya II parish prefer a double vault design to one which uses bucket. The findings also reveal that reuse of sanitized urine and faecal matter within the community is not possible since there is no space for urban agriculture. However, the respondents acknowledged a willingness to eat or buy food from a garden fertilized with sanitized urine and faecal matter. It was also found that there are no cultural and religious beliefs against reuse of sanitized urine and faecal matter. Some challenges that affected implementation of the pilot project were people’s reluctance to adopt at the beginning, delayed completion of some facilities and part time employees. Currently there is limited replication of toilets because of low cash income among the residents, delayed completion of some facilities and sceptical views by some residents.</p><p>Among the difficulties faced in use of toilet include forgetfulness by some people to spray ash after defecating, misplaced water entering the toilet vault during cleaning, children playing with the urine container etc. The provision for anal cleansing for Muslims, squat hole covers, closed urine chamber among others were suggested for system improvements. The study recommends more awareness campaigns through social marketing of toilet and reuse of nutrients, modification of design, government’s commitment and household change of behaviours are fundamental for encouraging more adoption and replication of the toilets.</p>

Perception on Support Provided to Orphan Children in Foster Care Placement in an Urban City of Windhoek (Namibia)Nshimyimana, Brigitte January 2008 (has links)
<p>Zambia is a highly urbanized country with 60% of its urban population residing in low cost areas also called peri-urban, slum or informal settlements. The increase in urban population attributed to rapid migration and urbanization due to political and economic changes has taken a toll on service provision as the infrastructure development and service provision has failed to meet the demand. For the 33 peri-urban areas in Lusaka, the water supply and sanitation has been poor, inadequate and unreliable with the coverage being slightly above 50% for water while 90% of the urban population does not have access to the much needed sanitation. The low coverage is a result of lack the financial capacity on the part of the service providers to extend services to un served areas.</p><p>This research focuses on the strategies to provide sustainable water and sanitation services to peri-urban areas to ensure improved accessibility through the expansion of infrastructure and attainment of full cost recovery. In this era of increasing migration to unplanned settlements where the services are inadequate, alternatives to public provision of water and sanitation services need to be put in place. One of the alternatives is the public-private partnership which encompasses the society, private and the civil society. As has been found in the study the best alternative should not only be completely bottom up but should also be more demand driven and be able to provide for greater contributions from the affected communities.</p><p>The hypothesis of the study is to ascertain if provision of water supply to the Peri-Urban Areas (PUAs) can be achieved through the partnership between the water utility and the small scale water providers. Therefore, the objectives of the research are to: evaluate and compare the current service provision to the peri-urban areas by the utility and small scale providers in terms of technical, social and institutional arrangements and determine the best way of ensuring sustained service provision to peri urban areas and show how partnership can be the best solution to improving service delivery to these areas.</p><p>Service provision in PUAs can not be achieved without the involvement of all the stakeholders especially the community who are also the users and whose major role is paying for the service to enhance sustainability. In this study the Small Scale Water Providers (SSWP) users were found to be satisfied with the service provided than the utility users who felt that more needed to be done. The two providers are found to have different strengths which when combined would enhance service provision. The collaboration between utility with its competence in water supply, technical installations, water quality testing and SSWP with theirs in community involvement, cost recovery, effective operation and maintenance and demand driven water schemes have to be merged to achieve the intended goal and it is also an indication that the two can complement each other. Utility should therefore consider opening investment accounts for all the areas so as to detach PUAs needs from the general plan and eventually budget as they would be self sustaining and enhance willingness to pay for the users. The SSWP should therefore be viewed as partners by all and licensing should be considered by the government for the benefit of the urban poor.</p>

Previous issue date: 2012-08-31 / Contemporary the process of global urbanization is notable for the intensity of its expansion, also in Brazil, where the great majority of the population lives in urban areas, with a vibrant aspect of the dynamics of this occupation the configuration of a space called peri-urban. From this overview, this paper aims to analyze the consequences of the interaction between the land market and public interventions, in the formation and orientation of the dynamics of occupation of peri-urban areas, in the west region of the city of Juiz de Fora (Minas Gerais), also known as Cidade Alta (Uptown) in almost all its entirety, seeking to understand the role and influence of market land and public interventions in the process of its expansion, passing their socioeconomic characteristics, their occupation and the growth of the main neighborhoods that comprise it. For this purpose, besides the analysis based on a mixed methodology data of the market value of their land and their peculiar housing market, I sought to compare the numerical data with an analysis of features supported by observations of its main components and causes of the phenomena analyzed.The corpora related to the object of research are coming from data from the Territorial Urban Property Tax - a property tax, between the years 2000 to 2010, in each neighborhood and its subdivisions, as well as listings of the two largest newspapers in circulation of Juiz de Fora: Tribuna de Minas and Diário Regional. The result is an empirical analysis of the vectors of expansion in the region studied, addressing different forms of land use, especially for the installation of condominiums and discussion of socioeconomic and growth features, which in turn, show a highly speculative real estate in the region. It is intended to provide information to better understand this specific type of expansion, as well as the causes of the rise of areas similar to this locus, as a basis for the study of alternatives in terms of public policies in support of a concept of right to housing in their broadest sense of equity of access to public equipments and basic infrastructure in peri-urban areas. / Contemporaneamente, o processo de urbanização global destaca-se pela intensidade de sua expansão, também no Brasil, em que a grande maioria da população vive em áreas urbanas, sendo um aspecto pujante da dinâmica dessa ocupação a configuração de um espaço denominado periurbano. A partir desse panorama, a presente dissertação tem como objetivo analisar os reflexos da interação entre o mercado de terras e as intervenções públicas, na formação e orientação da dinâmica de ocupação de áreas periurbanas, da região Oeste da cidade de Juiz de Fora (Minas Gerais), também denominada como Cidade Alta , em quase toda a sua totalidade, buscando compreender a atuação e a influência do mercado de terras e das intervenções públicas no processo de sua expansão, perpassando suas características socioeconômicas, a sua ocupação e o crescimento dos principais bairros que a compõem. Para tanto, além da análise baseada em uma metodologia mista dos dados do valor venal de seus terrenos e o seu mercado imobiliário particular, buscou-se confrontar os dados numéricos com uma análise apoiada em observações de características de seus principais componentes e causas dos fenômenos analisados. Os corpora relacionados ao objeto da pesquisa são advindos de dados do Imposto Predial Territorial Urbano - IPTU, entre os anos de 2000 a 2010, em cada bairro e seus loteamentos, bem como anúncios dos dois jornais de maior circulação de Juiz de Fora: Tribuna de Minas e Diário Regional. O resultado é uma análise empírica sobre os vetores de expansão da região estudada, abordando as diferentes formas de ocupação do solo, com destaque para a instalação de condomínios e a discussão de aspectos socioeconômicos e de crescimento, que por sua vez, apontam para um mercado imobiliário altamente especulativo na região. Pretende-se fornecer subsídios para se melhor entender esse tipo específico de expansão, bem como as causas do surgimento de áreas semelhantes a esse lócus, como base de estudo para alternativas em termos de políticas públicas em prol de um conceito do direito à moradia em sua acepção mais ampla da equidade do acesso a equipamentos públicos e infraestrutura básica nos espaços periurbanos.

Périurbanisation et Modernité à Hô Chi Minh-Ville. Etude du cas de l 'arrondissement Binh Tân. / Suburbanization and Modernity in Hô Chi Minh City. Case study of the district Bình TânNgo, Thi Thu TrangVincent 13 March 2014 (has links)
La croissance de l’urbanisation, par son importance et sa rapidité, pose des problèmes considérables dans beaucoup d’endroits du monde, en Asie du sud-est et notamment au Vietnam où le potentiel d’accroissement urbain est extrêmement fort. Au Vietnam, dans les grandes agglomérations de ce pays, le processus d’urbanisation est encadré dans des limites territoriales définies par l’Etat et collectivités locales. Mais il se fait en outre de façon spontanée en réponse aux besoins de nombreuses populations qui viennent de la campagne et travaillent dans les zones industrielles. Le problème de définition du périurbain à HCM Ville est abordé dans notre recherche de façon à tenir compte du contexte local mais surtout des enjeux théoriques que pose le périurbain en tant que phénomène sociogéographique. L’interrogation sur les liens d’interdépendance entre périurbanisation et modernité traverse nos réflexions. La recherche vise à comprendre comment émergent dans les zones périurbaines de nouvelles formes d’urbanité que l’homme tisse avec son milieu de vie et qui sont marquées par la modernité. Plus particulièrement, il s’agira d’examiner comment certains types d’habitats lient diverses catégories de population et diverses formes d’urbanité en milieu périurbain, afin de dégager la dimension sociale et culturelle de l’adaptation à la nouvelle situation et du développement durable. La thèse se concentrera sur trois types de population dans des types d’habitats différents, qui sont parmi les plus affectés par l’expérience de la confrontation à la modernité : les jeunes, les femmes et les personnes âgées. Notre approche géographique consiste à caractériser la zone périurbaine par les outils de télédétection, statistiques et cartographiques, et aussi au moyen de méthodes d’observation participante et d’entretiens approfondis, grâce auxquelles on peut voir comment les gens construisent leurs lieux et vie et leur donnent du sens. Ils font preuve d’adaptations personnelles importantes qui se traduisent par de nouvelles façons de vivre et de participer à l’émergence de nouveaux lieux d’urbanité. / Peri-urban areas, with their landscapes of closely mixed rural and urban activities represent a form of urbanization that is emerging a question on the traditional urban - rural duality. The suburban Hô Chi Minh-City ( HCM-City ) is dealt in our thesis in the local context taking into account the theoretical issues raised by this socio-geographical phenomenon. Three types of inhabitant were identified in our study and are characterized by their different way of living the suburban space in HCM-City. They participate in the construction of very revealing field interactions between the countryside and the city, between tradition and modernity. Representations and actions revealingthe modernity which is distancing itself from traditions, can affect all residents. However, they are more easily identifiable in certain population groups, more specifically those three which are the most affected by the experience of confrontation with modernity: women, youth and the elderly. Their social roles are more likely to be modified by the peri-urban context, which results in some aspects of lifestyle where high pressure to change the behavior of their daily life including their mobility is observed. The analysis of new livestyles both in their positive and negative aspects allows us to understand the changes that affect social relations, religious practices, the role of women and family conflict, mobility and behavior of youngand older people as well in the studied peri-urban areas. The analysis also shows that the geographic distribution of the three types of habitathas conditioned the emergence of a new tissue of socio- spatial relations in peri-urban areas of HCM-City.
