An analysis of hazardous waste across different land use zones in Musina Local Municipality, Limpopo Province, South Africa

Nematshavhawe, Happy Andani January 2021 (has links)
Thesis (M.Sc. (Geography)) -- University of Limpopo, 2021 / Hazardous wastes (HW) refer to wastes that may or tend to cause adverse health effects on the ecosystem and human beings. These wastes pose present or potential risks to human health or living organisms, due to the fact that they are: (i) non-degradable or persistent in nature, (ii) can be biologically magnified, (iii) are highly toxic and even lethal at very low concentrations. Various types of production activities in South Africa generate many by-products, which are usually discarded but often turn out to be sources of acute environmental hazards. If not contained and handled appropriately, waste, including HW can cause significant problems. Unattended HW lying around leads to unhygienic conditions resulting in health problems. Increasing population growth, accompanied by rapid urbanization and industrialization, increases the volume of HW generated in the country. Improper waste management is aesthetically unattractive and impacts negatively on tourism by creating blight on South Africa’s beautiful landscape. The aim of the study is to assess how HW is discarded across different land use zones in the Musina Local Municipality in order to reduce and manage the negative impacts that they exert to the environment and human health. The objective was to: (i) analyse the state and management of hazardous waste discarded by beauty salons of the central business district of Musina; (ii) Elucidate the state and management of hazardous waste discarded by households located in the suburbs of Musina; (iii) Document the state and management of hazardous waste discarded by automotive workshop located in the Industrial zone of Musina and (iv) Develop tailor-made recommendations for the safe management of hazardous waste in the town of Musina, Limpopo Province, South Africa The study was conducted in Musina Local Municipality in Limpopo province, South Africa. Musina is the northern town in the Limpopo Province of South Africa. The study sites were divided into three land use zones; central business district (CBD), suburban area, and industrial zone. In terms of methodology observations, a datasheet and a semi-structured questionnaire were used to collect data on HW management across three different land use zones. A total of 73 semi-structured questionnaires (55 in suburban area and 10 in industrial zone and 8 in the Central Business District) were employed to document quantitative and qualitative data. Observations were used to identify the types and document quantity of HW discarded by all participants. The researcher opened the weekly municipal refuse bags that stored discarded products to list and count HW products. The information was captured on a datasheet, which recorded data on type, quantity and separation of hazardous waste from general waste. Data was analysed via descriptive statistics. Results from Central Business District (Salons) shows that nail varnish bottles were the most discarded HW product with 250 discarded per week by all eight salons. Other HW products discarded include artificial nails, hair dye containers, plastic combs, vinyl gloves and disinfectant containers. All salons practice the same disposal method; making use of municipal refuse bags for temporary storage, which is then transported to the municipal landfill site for final disposal. None of the participants separate waste; reasons being lack of awareness of separation management. Shop owners and employees’ attitude towards HW management was neutral while their level of knowledge on the environmental and human health impact was rated low. Seventy-five percent of the respondents were not aware that the products they discard are hazardous. Results from Suburban area (household hazardous waste) shows that home cleaning products were the most discarded Household Hazardous Waste (HHW) product with 237 discarded per week by all 55 sampled households. Other HHW products discarded include personal cleaning products, miscellaneous items, automotive maintenance and gardening products. The 50 households practice the same disposal method; making use of house bin (usually pedal bins). Once the bin is full, they dispose it to the outdoors wheelie bins. The remaining five household dispose of their waste directly to the outdoor bin. None of the participants separated waste; main reasons being lack of awareness of separation management. Participants’ attitude towards HW management was neutral while their level of knowledge on the environmental and human health impact was rated medium. Seventy-three percent of the respondents were aware that the products they discard are hazardous. Results from Industrial Zone (hazardous waste) shows that plastic components were the most discarded hazardous waste (HW) product with 31 discarded per week by all 10 sampled automotive workshops. Other HW products discarded include lead-acid batteries, automotive used oil and paint containers. Automotive workshops practice different storage and disposal method; making use of drums, large containers and old scrap car as a temporary storage place. Once the temporary storage is full, 50% opted for recycling while 30% dispose of their waste to the landfill site; the remaining 20% burn their waste in their premises. A large majority (80%) did not separate their waste; main reasons being a lack of awareness of separation management. Participants’ attitude towards HW management was positive while their level of knowledge on the environmental and human health impact was rated low. Half of the respondents were aware that the products they discard are hazardous. Many studies have looked at the comparison between wastes discarded in the rural versus urban area with little attention on specific enterprises. It is more realistic to consider other enterprises because different activities generated different waste. This study was able to assess how waste is discarded in different enterprises such as salons and automotive workshop with an addition of residential waste. To the best of our knowledge this is the first study of this kind. Future research can look at other enterprises such as HW from restaurant or as far as HW discarded by mining sector. The study recommends that the salon enterprise obtains a HW certificate prior to operating a salon, this will increase awareness and make employees more knowledgeable on issues relating to the management of HW. Most of the wastes discarded by sub-urban area were recyclable materials. The municipality can look into collecting recyclable materials separately and taking it to the recycling facilities. It was shocking to find out that there are automotive industries that burn their waste (without even separating). This poses a serious danger in terms of air pollution and the possibilities of containers exploding; therefore, there is an urgent need to educate people in the automotive industry.

A Baseline for Downtown Transit-Oriented Development: Planning for Success in the Loyola Corridor

Bennett, Peter 01 October 2011 (has links)
Transit-Oriented Development (TOD) in downtown areas is a distinct form of new development, creating walkable districts and 24-hour neighborhoods. A new streetcar on Loyola Avenue in the New Orleans Central Business District was planned to encourage new development in the area. By analyzing the current land uses and values, projections of future change predict over $500 million in added value. For this development to become a successful TOD, policies must encourage uses that generate ridership and increase walkability. Although the Loyola corridor has many historic attributes of a transit-oriented downtown, it currently lacks neighborhood identity. The new development associated with the Loyola streetcar has the potential to become a downtown TOD.

Historic Preservation Leading to Heritage Tourism as an Economic Development Strategy for Small Tennessee Towns.

Justice, Robert A. 15 December 2007 (has links)
Historic preservation has been a successful economic development tool that has led to heritage tourism in some Tennessee towns but not in others. The problem studied was to determine if there was a set of tangible attributes a town must possess to be successful in using historic preservation as an economic development tool. Through an extensive literature review, 59 predictor variables were identified and arranged into 6 research questions looking at the tangible attributes related to town demographics, geography, organizational structure, historic preservation organizations, heritage tourism organizations, and town financial structure. Data were collected from a mailed survey of 32 town managers. The response rate was 68.8% (N = 22). Secondary sources, such as U.S. Census data, were used to collect data when those sources appeared consistent and mandatory. The study used logistic regression analysis to compare successful towns, defined as those towns in the upper third of study towns for tourism expenditures per capita, with less than successful towns. The 32 study towns met the criteria of having a 2003 population of fewer than 10,000 and a nationally-recognized historic district that coincided with the towns' central business districts. The results of the logistic regression analysis on the individual predictor variables indicated that 5 were statistically significant--median age, distance to a major city, restaurant beer sales, Grand Division, and merchants' association. Constraining the final predictive model (Garson, 2006) to no more than 1 variable per 10 cases 3 led to the inclusion of median age and merchants' association as the 2 predictor variables that provided the highest predictive value of correctly classified towns (95.8%). In summary, this study is inconclusive in determining whether historic preservation leads to heritage tourism and can be used as an economic development tool by small Tennessee towns. However, it has been established that 5 attributes or characteristics of small towns does contribute to the probability of success and that median age and the existence of a merchants' association proved to be the best predictive model.

An exploration of the role of social systems in urban renewal : an urban planning perspective / Gert Hendrik Meiring

Meiring, Gert Hendrik January 2013 (has links)
Cities, as complex social systems within society, are the most complex of all human systems. An increase in this complexity is anticipated since projections estimate that two-thirds of the world’s population will be urbanised by 2030. Cities are “melting pots” of cultures and systems that share the same spatial environment. In South Africa this challenge is exacerbated by one of the highest urbanisation rates in the world. Urban growth implies tremendous change. City centres are especially at risk to structural changes of urban growth and consequent urban decay. Governments commonly adopt urban renewal to cope with changing urban environments. However, the long term sustainability of current urban renewal practices is questioned as they tend to over-emphasise economic revival and physical intervention. The focus on people is often missed and misunderstood, even though social dynamics are the driving forces in cities. Urban renewal is complex and multi-dimensional. In theory it moved away from the linear top-down approach that focused on the physical environment towards a more inclusive, integrated and socially oriented process. This is reflected in paradigm shifts in planning thought from a physical planning and design based product orientated discipline (as reflected in historical and modernist planning approaches), to a socio-political process in which the communicative planning paradigm is the most recent post-modern theory. Understanding cities as social systems and exploring their role in central business areas to include them in urban renewal are important starting points when urban planners work with urban renewal initiatives. As research about social systems and their role in urban renewal is limited in South Africa, this study provides a step towards acknowledging and including urban social systems proactively in urban renewal initiatives. This is especially relevant in central business districts of medium sized cities such as Potchefstroom (Tlokwe Municipality) that experience urban decay and where urban renewal initiatives have not yet been implemented. The Mission Statement of the Tlokwe Municipality emphasises the need for social understanding in the economic sphere, as this enjoys a high priority in the development choices made. A qualitative ethnographic research approach was followed to explore the role of social systems in this context. This allowed the research to capture social dynamics in its natural setting where no extraneous influences occur. This resulted in rich textual descriptions of how people experience social interactions and the physical environment. Unstructured and non-participant field observations and face-to-face, in-depth, semi-structured interviews were used as methods to identify social systems within the research context and to understand interactions and behaviour patterns that emerge from this context. Findings from the observations expose a dynamic and cyclical network of inter- and intrarelationships that culminate in continuous intense interaction amongst three social systems, namely the private sector, community groups and the general public. Pro-social behaviour patterns (behaviour that promotes good social relations) were observed, including cultural relativism and social awareness. Findings from the interviews provided insight into how social systems interact with one another and with the physical environment. Themes that emerged for the data to describe interactions among social systems include material support, friendliness, cooperativeness, comfortableness, accommodativeness, fixed and established relations and respect for one another. This creates a vibrant, synergetic environment conducive to sustainability and describes an environment of hope. The counter-experience includes forced flexibility and adaptiveness (due to unmet physical needs), feelings of being unsafe, limited choices and a general dissatisfaction with the physical environment in terms of its support. This describes an urban environment of fear. The role of social systems in terms of urban renewal is inclusive, participating and socially sensitive. They should be catalysts for socio-economic functions, contribute to maintenance and act as stakeholders. Based on the above, the study offers recommendations to include social systems in urban renewal in terms of the research process and method to be followed, how and where to include social systems in urban renewal projects and suggestions for physical change to make the area more supportive to the social dynamics. Practical guidelines are offered related to the practice of observations and interviews for the identification and exploration of social systems. The following suggestions are made regarding the urban renewal process: pro-active inclusion of social systems throughout the process in the pre-project stage, during the urban renewal project and post-project stage. Interventions to enhance the physical environment include provision of special requests, access to open space, application of green construction and local distinctiveness. As planners play a proactive role in urban renewal they may contribute to enhancing the sustainability of urban renewal initiatives by understanding urban social systems and their role in city centres in order to acknowledge and include them as important partners. / MArt et Scien (Urban and Regional Planning), North-West University, Potchefstroom Campus, 2013

Intra-metropolitan agglomerations of producer services firms: the case of graphic design firms in metropolitan Melbourne, 1981-2001

Elliott, Peter Vincent Unknown Date (has links) (PDF)
Graphic Design is one part of the producer services sector of the modern metropolitan region. It is a sector that has experienced considerable development in terms of number of firms through demand created by the expansion of advertising and multi media. To date research has established that producer services, particularly finance related ones, agglomerate in the central city to take advantage of the agglomeration economies available in large metropolitan areas. This thesis argues that one of the key factors for the agglomeration of graphic design is the need for face-to-face communication with clients and other firms. There has been some work undertaken looking at the location of non-finance producer services, such as design, although these have been presented as snapshots at a point in time.This thesis extends this understanding through an analysis of agglomerations of graphic design firms over a twenty year time horizon. Using details of firm location in Melbourne every five years from 1981 to 2001 the thesis uses a geospatial analytical technique to identify agglomerations and explores the change in the size, location and density of agglomerations of firms. This research shows that the initial agglomeration of 1981 was still present by 2001 and had been joined by a number of new agglomerations ringing the Melbourne CBD while at the same time there has also been a dispersal of firms to the middle suburbs. In order to provide some insight in to the agglomeration of graphic design firms this research also examines the geography of two industries allied to graphic design: advertising and printing. This research shows that graphic designers and advertising agencies tend to locate in similar parts of inner Melbourne which may be due to the need for face-to-face contact between fims in these two industries.

都市商圈土地混合使用自治管理模式-以師大商圈為例- / The model of autonomous management in mixed use of land of urban business area : the case study of Shih-Da business district

趙元瑞, Jao, Ruan Ruzy Unknown Date (has links)
土地使用分區是否允許夜市相關業別的存在,是否違反土地使用分區規定,一直以來存有疑慮。現行臺灣法律中不論是土地法或都市計畫法,針對土地使用分區已訂定相關的規則與規章,主管機關亦頒布有管制準則及函令以資遵循,諷刺的是,夜市周邊的住戶與該夜市所撐起的商圈,為了個別的利益,爭吵、訴訟甚至於鬥毆的情況屢見不鮮。 本研究利用Ostrom (2014)所建立的自主管理理論,探討商圈內部在集體選擇過程,如何有效選擇管理既有住商混合商圈對環境的負面衝擊,並提出建立住商混合商圈街區管理模式之建議。透過文獻回顧、個案研究、與深度訪談,本研究成果顯示,師大商圈未來管理模式的策略有四個可能性:因地制宜模式的採用、社區居民與商圈商家共存共榮的期待、商圈組織自主管理運作機制的建立、以及公部門與商圈組織之間的協調溝通。 本研究在師大商圈土地分區管理機制上,為了同時增加土地使用效率及考慮社區居民的權益,平抑破壞商圈整體利益的個人利益,應可使用具彈性調整機制的土地分區管理,而彈性調整的依據,係可透過政府公部門、商圈內商家組織、社區組織三方面共同研擬,制定相關施行辦法。 / It is questionable for a long time that whether the permission of the business of night market within land zoning violates the regulations of zoning. Albeit relevant regulations of land zoning have been established and on acted, and enforced ironically, for pursuing individual profits and personal benefits, the residents and the vendors who inhabit in the business area have to face abundant disputes and litigations. The self-governance on common pool resource from Ostrom (2014) would be utilized to discuss the process of collective selection within business area, and to see how the effective management to deal with the negative impacts of mixed-use business area could be selected and eventually to raise a management model to cope with mixed-use business area. By literature review, case study, and interview, the four possible management models for NYNU commercial Area are: the management with local conditions, the collaborations between residents and vendors, the mechanism of self-governance in business organization, and the coordination and communication between the public and business organizations. Furthermore, basing upon the mechanism of the management of land zoning within NTNU Commercial Area, the elastic land zoning should be adopted to increase the effectiveness of land use and the rights and interests of residents. The basis of elastic management of land zoning can be established through the collaboration among the governments, business organization, and resident organization then.

L'historique du quartier de la Défense et ses représentations dans la presse : l'évolution de la perception d'un grand quartier d'affaires / History of La Défense district and its representations in the press : the evolution of the perception of a big business district

Pac, Bertrand 27 June 2016 (has links)
C’est entre 1960 et la fin des années 1980 que se situe en France la grande période du bouleversement architectural qui donne naissance au quartier d’affaires de La Défense. L’histoire de cette monumentale opération d’aménagement de « l’Ouest Parisien » vue par les journalistes révèle trois étapes dans l’évolution de ce projet qui vise à doter la capitale d’un « Manhattan français », ou mieux trois états forts constitutifs d’opinion successifs : celui de l’enthousiasme qui a présidé à la présentation par l’EPAD en 1964 du premier plan de masse de l’opération et à ses premières réalisations sur le terrain, celui du doute et de la contestation liés à l’histoire agitée qu’a connu durant les années 1970 ce chantier gigantesque alors en proie aux turbulences d’une crise économique qui en hypothèque l’avenir et en trouble le dessein final, celui de l’indéniable adhésion à la réussite d’un projet qu’a illustré l’érection en 1989 de la « Grande Arche de La Défense ». Savoir ce que les journalistes ont pensé pour comprendre l’évolution de « La Défense » est ainsi la première raison de l’investigation historique menée à propos de ce quartier à l’urbanisme révolutionnaire. Mais il en est une seconde, car l’histoire n’est pas seulement une pourvoyeuse du présent ; elle est aussi génératrice de représentations dont le retentissement joue de concert avec l’évènement objectivement établi. Et, à ce titre, l’étude de « La Défense » comme phénomène historique de cristallisation de l’opinion de la presse offre un exemple particulièrement net de l’apport qu’un pôle d’attraction aussi efficace que le quartier de « La Défense » fournit à l’histoire contemporaine de l’urbanisme. Ainsi, après avoir décrit le processus historique révélé par le regard de la presse, l’interprétation des représentations de la ville nouvelle sera l’occasion de démontrer que la réalisation du quartier de La Défense a été davantage concernée par la conscience de l’évènement que par l’évènement lui-même dès lors que cette opération constituait, par sa nature propre, un phénomène médiatique de première grandeur. / It is between 1960 and the end of the 1980s that lies in France the great period of the architectural shift that gives birth to the La Défense business district. The history of this monumental “Ouest Parisien” planning operation seen by journalists reveals three stages in the evolution of this project which aims to establish the capital of a “French Manhattan”, or better three strong constituent states of opinion successive : one of enthusiasm which presided over the presentation by EPAD in 1964 of the first mass of the operation plan and its first achievements on the ground, that of doubt and contestation related to the turbulent history that has experienced during the 1970s this construction giant while embroiled in the turbulence of an economic crisis that threatens the future and disorder the final design, one of the undeniable accession to the success of a project that illustrated the erection in 1989 of the “Grande Arche of La Défense”. Know what journalists thought to understand the evolution of “La Défense” is the first reason for the historical investigation about this revolutionary urban district. But it is one second, because the story is not just a purveyor of the present ; it is also generator of representations which the impact play in conjunction with the objectively established event. And, as such, the study of “La Défense” as a historical phenomenon of crystallization of the opinion Press provides an example particularly net of the contribution as a pole of attraction as effective “La Défense” district provides to the contemporary history of urbanism. Thus, after describing the historical process revealed by the gaze of the press, the interpretation of the representations of the city new will be an opportunity to demonstrate that the achievement of “La Défense” headquarters was more concerned by the awareness of the event by the event itself as this operation was, by its very nature, a media phenomenon of the first magnitude.

Morfologinės struktūros transformacijos centriniame miesto rajone (Lietuvos pavyzdžiu) / Transformations of Urban Morphological Structure in the Central Business District (On the example of Lithuania)

Alistratovaitė, Inesa 23 February 2005 (has links)
As urban development in the 20th century has become the issue of global concern, more and more new territories have been occupied due to high intensity of the development. International conferences devoted to the regulatory issues of city development held within the current decade (such as HABITAT II held in Istanbul, 1996, ATHENS’98 – in Athens, 1998, URBAN 21 – in Berlin, 2000, and a conference in Brussels, 2001, etc) emphasized the majority of developmental aspects including the great focus on the necessity to further form urban structures with the priority of internal city development looking for more effective and more universal functional uses of the territories, restoration of the existing downtown areas and preservation of their original character. As other post-soviet countries, Lithuania has been also facing the need to reorganize various spheres including urban development. Urban territories have been dangerously expanded, especially during the soviet period, due to the increased general city building-up areas, mostly expressed by the territorial expansion rather than gradual and consistent development (by the use of internal reserves of the city). After the restoration of Lithuanian independence, privatisation, changed character of housing construction, return of land and real estate to the previous owners and increasing value of land under the free market conditions remarkably modified the nature of urban development in Lithuania, at the same time revealing the...
