Public participation as a factor in the development of policy : a case study pf the KwaZulu-Natal Waste Management Policy process, 1996- 2001.

January 2002 (has links)
This study reviews some of the trends in the theory and practice of public participation processes as an element of policy development. It attempts to locate public participation within a theoretical framework for policy development based on the work of Kingdon (Agendas, Alternatives and Public Policies, 2nd ed. 1995) on policy streams, and that of Roe (Narrative Policy Analysis. 1994) on the use of discourse analysis. It uses the KwaZulu-Natal Waste Management Policy process as a case study and shows that it is possible to combine these two theories to come to a better understanding of the way in which policy is arrived at. The policy streams proposed by Kingdon are identified in the case study and the 'crisis', which moved the issue of waste management onto the decision agenda, is described. Two dominant narratives that emerge from a series of interviews are discerned, together with two counter narratives. By comparing and contrasting these a metanarrative is developed that meets Roe's criteria for telling a better story and so becomes the basis for the final policy. Public participation is shown as being a useful way of ensuring that alternative 'stories' are included in the shaping of policy and so allowing a metanarrative to emerge. Some conclusions about the implications of the analysis for future processes are drawn. / Thesis (M.A.)-University of Natal, Pietermaritzburg, 2002.

Waste management through recycling and composting : a case study of some schools in greater Edendale, Pietermaritzburg, KwaZulu-Natal.

Nxumalo, Felix Thembinkosi. January 1999 (has links)
The study investigated the involvement of primary and secondary schools in waste management through recycling and composting, and the perceptions of teachers and pupils with regard to waste management. It also investigated the local municipality's attitude towards using schools to inculcate the culture of own waste management. It further investigated some of KwaZulu Natal's recycling industries/agents' attitudes toward using schools as "mini" depots for collection of recyclable materials. It was found that according to teachers perceptions most of the primary schools are engaged in waste management practices through recycling and composting, while secondary schools are less involved in waste management practices through recycling and composting. The results revealed that 53% of primary schools are involved in recycling projects, while only 10% of secondary schools are involved. It was also found that both primary and secondary school teachers are willing for their schools to be involved in waste management practices. Primary school pupils are more enthusiastic in collection of recyclable materials and composting projects as means of waste management as compared to secondary school pupils who are less interested. The results further revealed that there are no educational programmes that are initiated by the Pietermaritzburg-Msunduzi Municipality to inculcate the culture of waste management among the school pupils. There are a few industries that collect recyclable materials from schools in Greater Edendale by putting paper banks in some of the schools. It was also found that the Keep Pietermaritzburg Clean Association has an educational programme for waste management with some of the schools in Greater Edendale. This programme is called Environmental Award System for Youth (EASY), whereby schools receive awards for activities that they are involved in to manage waste. It is recommended that organisations such as the Greater Edendale Environmental Network be encouraged to establish educational programmes to help motivate and make pupils aware of the value of waste management. Recycling industries should also target primary and secondary schools for collection of recyclable materials, rather than only focusing on tertiary institutions. If this is done children will gradually become aware of the concept and value of recycling. Through the involvement of schools in waste management the public can be educated more to the role of responsible waste disposal and management. / Thesis (M.Env.Dev.)-University of Natal, Pietermaritzburg, 1999.

A solid waste pilot study and proposed management recommendations for Ezemvelo KwaZulu-Natal wildlife protected areas.

Hatton, Irene. January 2002 (has links)
Ezemvelo KwaZulu-Natal Wildlife (KZN Wildlife) needed to develop a solid waste management policy and strategy for their protected areas, as well as specific solid waste management plans for existing and new developments within these areas. These had to be in keeping with the principles of sustainable development, protected area conservation objectives, best practice and legislative requirements. A pilot study was thus undertaken at two large KwaZulu-Natal protected area visitor facilities, Hilltop Rest Camp in Hluhluwe Game Reserve and Sodwana Bay Rest Camp, to investigate the types and amounts of solid waste generated . In addition, the solid waste disposal methods employed in 1984 and 2000, the disposal options available and the constraints and impacts of solid waste disposal throughout the protected area system were investigated. A comparison was made with solid waste production and management at Skukuza Rest Camp in the Kruger National Park as well as with various international waste sources. The information was presented in the form of histograms for comparison and tree cluster analysis was used as a heuristic tool to discuss the results. Hilltop and Sodwana Bay Rest Camps produced similar waste although its composition varied according to the specific source of production within the visitor facility . The waste produced at KZN Wildlife protected area visitor facilities had a similar composition to that produced at Skukuza Rest Camp. Audits of waste management practices at Hilltop, Sodwana Bay and Skukuza indicated that KZN Wildlife was not adequately managing the solid waste at their two protected area visitorfacilities. However, solid waste was being responsibly disposed of at Skukuza Rest Camp. The type of waste produced at protected area visitor facilities in a number of other African countries and Australia, was similar in composition to that produced in South African protected areas; all were similar to that produced in developed, westernised countries. A survey in 1984 of waste disposal methods in 32 KZN Wildlife protected areas, indicated that disposal to municipal landfill was only practised by protected areas less than 5 000 ha in size and less than 30 km from a municipallandfill. The current (2000) survey showed that disposal directly to landfill without reduction within protected areas had been discontinued, and that there was an increased proportion of waste disposal to municipal landfill. Such disposal was primarily limited to areas of less than 10000 ha and less than 40 km from such a landfill. The main constraints on the choice of waste disposal method were the cost of transport and limited budgets. A draft solid waste management policy and strategy were developed. The policy set out the legal requirements , ecological objectives and constraints of solid waste disposal in protected areas and also the preferred disposal options. The strategy set out the waste disposal methods available and their associated risks, likely impacts, opportunities and implications for management. The use of a simple matrix, that combined transport costs (represented by distance to a municipal landfill site); the size of the protected area (assumed to reflect the amount of solid waste generated); and the environmental risk of leachate production (as indicated by the climatic water balance), with suitable waste disposal options, was recommended. This matrix was designed to assist in the objective implementation of the draft waste management policy and in selection of an appropriate waste disposal method for each protected area. The draft policy and strategy were applied to produce a solid waste management plan for a new development in Umfolozi Game Reserve. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2001.

Informal recycling and resource recovery at a municipal open dumpsite : a case study of Hulene dumpsite.

Domingos, Leonor Joaquim. January 2001 (has links)
Poverty in its many guises - poor housing, no employment, indifferent health and hunger is a driving force for scavenging. In most developing countries, the informal recovery of material from waste is a common survival strategy for the poor. In fact, up to 2% of populations in developing countries depend on recovering, re-using and selling waste materials from streets, dumpsite or landfills for their livelihood. The aim of this study was to develop an understanding of the socio-economic conditions affecting the scavengers and scavenging activities at the Hulene dumpsite in Maputo. This study set out to develop a conceptual framework depicting scavenging, its problems and opportunities. This was used to structure the research. The main issues addressed were: • The driving forces of scavenging where poverty is the major factor. • The organization of scavengers and scavenging activities showing that there is no formal organization of scavengers, which leads to exploitation of vulnerable groups. • The reaction from the national and local authorities, with the prevalence of a repressive policy and absence of support. • The gender dimension on scavenging activities; and • The perception of health risks. The findings are that scavenging constitutes a means of livelihood for poor people. These activities respond to the market demand and not to environmental considerations. However, in performing scavenging activities which results in informal recycling and resources recovery, people generate environmental benefits, economic benefits and social benefits. Other findings are that the informal organization of scavengers increases the exploitation and the health risk of scavengers. Thus, organization is a key to the success of scavengers and indirectly to the municipal economy. It is concluded that the framework set out in this thesis is useful in the sense that it illustrates the factors which influence scavenging activities. This framework can be used for further research in similar situations. It is also concluded that prohibition of scavenging activities would have undesirable consequences for the economy of Maputo in particular and of Mozambique in general. Thus, since this activity brings benefits to scavengers and to society, the government should support and stimulate this activity and not persecute those who provide this service. Consequently, as a recommendation, government, local communities and NGOs are called upon to support scavengers. The formation of scavenger co-operatives can promote sustainable grassroots development in this sector of the population. / Thesis (M.Env.Dev.)-Unversity of Natal, Pietermaritzburg, 2001.

The regulation of the removal of hazardous shipwrecks in South African waters and a discussion on the adoption of the Nairobi International Convention on the Removal of Wrecks, 2007.

Ramsakkan, Yinita. 12 August 2014 (has links)
International trade in large amounts of commodities resulted in the recent growth of the shipping industry. With larger ships being constructed to meet land based demands for various types of commodities combined with the unpredictable and often perilous conditions at sea, the risk of a shipwreck arising becomes more likely. Not only do these wrecks pose a danger to the environment and to navigation but also, in the event of the shipowner escaping liability by abandoning the wreck for instance, the state affected by the wreck finds itself financially burdened by the costs involved in having the wreck removed. Moreover, an affected state cannot intervene and impose conditions to the shipowner to have a wreck removed if it occurred in its exclusive economic zone because the state’s jurisdiction is limited to preserving natural resources. Thus, despite drifting cargo and the ship itself posing a hazard to coastal states, they had no authority to intervene and issue a wreck removal notice. Recognising these safety concerns and lacunae in international law, the International Maritime Organisation formulated the Nairobi International Convention on the Removal of Wrecks, 2007, (“Nairobi Convention”) which was aimed at governing the regulation of removing wrecks whilst imposing strict liability on the shipowner, subject to the other liability Conventions and limitation of liability. However, after a survey was conducted by the Comitè Maritime International it was also established that national laws of many states such as the United Kingdom (“UK”) and South Africa were inadequate to enforce liability claims for costs incurred in removing a wreck. As a result, the Convention allows contracting states to apply the provisions of the Convention to their territorial sea. This dissertation will discuss relevant provisions of the Nairobi Convention and illustrate how it has been implemented and consequently reformed the law of the United Kingdom. The dissertation will then analyse the implementation strategy which enforces the Convention in the UK, with the aim of providing a suggestion of how South Africa should enforce the Convention into its national laws. This will lead to an assessment of the current legislative framework governing wreck removal in South Africa with the aim of establishing whether the law is need of reform and how this should be facilitated. / Thesis (LL.M.)-University of KwaZulu-Natal, Durban, 2013.

Timber supply and economic impact of mountain pine beetle salvage strategies

Moreira-Munoz, Simon 05 1900 (has links)
To address the scale mountain pine beetle (MPB) outbreak in British Columbia, salvage has become fully integrated with timber supply strategies. The objective of this thesis is to assess the economic impact of different salvage strategies depending on different attack levels, decay rates, and stakeholder discount rates. The study area is located in N.E. British Columbia where the MPB has not yet reached its peak and where susceptible to attack stands account for 40% of the area. Salvage strategies were modelled with a timber supply model (Woodstock) which uses a linear programming type II optimization approach. Performance of the model was assessed over a range of indicators such as NPV, profit, salvage proportion, species composition, inventory levels, and non-recoverable volume. Sensitivity analyses were conducted on harvest flow, discount rate, and ending inventory. The model was very sensitive to the intensity of attack and less sensitive to the decay level. The high level of attack resulted in large volume losses, mostly as un-salvaged inventory. Although allowable annual cut (AAC) uplifts have an economic benefit, they do not necessarily maximize the salvage of pine. Non-pine species are an important component of the salvage and these species are also essential for the future timber supply. If the objective is to ensure quality and quantity of the future forest, policies have to complement AAC uplifts by strongly encouraging the salvage of mainly pine-leading stands and management options that minimize the “by-catch” of non-pine species and minimize destruction of advanced regeneration during salvage. However, this has an opportunity cost for the private industry where the objective is to maximize profit. If the salvage strategy focuses on decreasing the impact on cash flows, achieving desirable ending inventory levels, avoiding salvage of stands after shelf-life, and reducing impact on non-attack species, then the current harvest level will likely lead to a mid-term timber supply fall-down. Using the fibre for bioenergy production is an alternative if managing for bioenergy can be integrated into harvest operations. However, unlike mill residues, the bioenergy supply has to fully account for harvest and transportation costs of dead wood to the mill.

Archaeology of the iron barque Sepia : an investigation of cargo assemblages

Souter, Corioli January 2007 (has links)
The Western Australian Museum houses a large collection of artefacts from late nineteenth century iron sailing vessels, wrecked en route from Britain. The bulk of this collection comprises cargo objects, destined for sale in the Swan River colony. The protection afforded artefacts, due to the integrity of these shipwrecks, presents new research opportunites for identifying particular classes of commodities which were considered either necessary or desirable for colonial consumers. This thesis examines the notion of material consumption as reflected in shipwreck assemblages in Western Australia for the later nineteenth century, prior to Federation. The research is concerned with the notion of cultural continuity from Britain through specific product selection, as demonstrated by the archaeological assemblages of iron barques importing general merchandise into the colony. Focusing on the Sepia (1898), the objectives include an appraisal of shipwreck cargo artefacts and their applicability to questions relating to consumer behaviour. While the primary objective of this study is on the identification of cargo assemblages, it presents an opportunity to study taphonomic processes and provide a method of relating the vessel to its cargo contents in order to answer broader questions about shipping practices, with a particular focus on stowage. This research also critiques shipwreck collections comprised of selectively recovered, unprovenanced artefacts and suggests appropriate methods for using such material.

Záchranné práce při požáru plavidla na vodní ploše s ohledem na vybavenost stanic JPO HZS Jihočeského kraje / The Rescue Operations at Fire of the Watercraft on Water Surface Considering the Equipment of Fire Station on the South Bohemia.

BOUBAL, Vojtěch January 2013 (has links)
At the beginning of thesis I want to describe few primary characteristics of the South Bohemia Region. It is a region with unique characteristics, which is frequently visited by domestic and foreign tourists. It is popular for its clean environment, historic monuments and especially for sport and recreational activities near water areas, which South Bohemia region has plenty of. Tourists are also frequently seeking recreational boating activities as ferry services for their travel and recration. The development of this economic phenomenon means more employment opportunities for the region, but it also increases chances of accidents and emergencies due to an unforseen accidents which can threaten the lives and wellbeing of the crew and the environment. Fire protection units should be fitted for an emergencies such as: drowning, drowned person search, icy water search and rescue and rescue in stream waters. The thesis is divided into the theoretical and the practical parts. The theoretical part deals with the definition of basic terms describing the issue of fire of the vessels as well as the tasks and procedures during fire fighting operations. It also presents a possible danger to rescuers exposed during operations such as rescue from the vessel burning on the water. There is a listing of the basic terms related to the complex vessel shape and the aquatic characteristics of the vessel. The practical part deals with the study of publications and current legislation, analysis of the Fire protection Units equipment and their readines for rescue work in case of a vessel fire. The enclosed data map illustrates a water area with ferry service in the South Bohemia Region and selected boarding platforms for fire protection units. It describes the use of container technology; modern and economical way of transportation used by the Fire and Rescue Service of South Bohemia Region since 2004. The proposed fire vessel, mounted on a standardize container frame and equipped with special container with stored technical equipment will be transported to the location of event by container carrier from FRS of South Bohemia Region. My theosis also describes the fire protection, fire equipment, personal protective equipment, equipment for working with hazardous substances, rescue tools, communication and portable emergency equipment which is normally used by the fire units of FRS of South Bohemia Region. To achieve the objective of the thesis and to answer the research questions, I did rely on the reference material obtained via search of the professional literary sources relevant to the Fire Fighting equipment and carrying out rescue work. To process the diploma thesis I did use the following: controlled interview with the station sergeants of various fire stations of FRS of South Bohemia, a collection of internal acts of the Ministry of Interior - General Directorate of Fire Rescue Service of the Czech Republic, a collection of internal acts - Regional Directorate of FRS of South Bohemia, Regulations of Mechanical services of FRS of CR and the methodological aids of the Ministry of Interior of CR. In conclusion I am describing the container of fire vessel and its use for rescue and fire-fighting work on water, as well as places where the terrain does not allow the use of mobile fire fighting equipment.

Ressecção abdominoperineal do reto após falha do tratamento radioquimioterápico do carcinoma anal / Abdominoperineal resection of the rectum after failure of chemoradiation therapy for anal carcinoma

José Humberto Simões Corrêa 11 May 2012 (has links)
INTRODUÇÃO: O tratamento padrão do Carcinoma Epidermoide do Ânus (CEDA) é a quimiorradioterapia ou radioterapia exclusiva. Os pacientes em que a terapêutica conservadora falha são tratados com Ressecção Abdominoperineal do Reto (RAP) de resgate. OBJETIVOS: Avaliar a sobrevivência com a RAP de resgate no CEDA, identificando os descritores favoráveis para sobrevivência maior e as características do agrupamento de variáveis relacionadas a descritores independentes de risco para mortalidade. MÉTODOS: Foram levantados dados através de 111 prontuários de portadores de CEDA, tratados inicialmente com quimiorradioterapia combinada ou radioterapia exclusiva e submetidos à RAP no período de outubro de 1982 a janeiro de 2011. RESULTADOS: A média de idade foi de 58 anos, 93 (83,8%) pacientes eram do sexo feminino e 80 (72,1%) da raça branca. O estadio cT3-4 compôs 66,7% e cN0 39,6% da casuística. A RAP foi indicada por persistência da doença (PD) em 61 (55%) pacientes e por recidiva (RD) em 50 (45%) pacientes. A ressecção cirúrgica sem resíduos tumorais (R0) foi realizada em 86 (77,5%) pacientes. O tempo médio de permanência hospitalar pós-operatório foi de 14 dias. A morbidade cirúrgica foi de 64,9%, sendo 78,3% dela devida às complicações da região perineal. Recidiva após RAP ocorreu em 68 (61,2%) pacientes, sendo 40 (58,8%) no primeiro ano do pós-operatório, a maioria locorregional (78%; 53/68). A mediana do seguimento foi de 16 meses (1,2-60 meses). Na análise multivariada, cirurgia R0 (p<0,001), invasão perineural vascular e/ou linfática negativa (p<0,0001) e linfonodo negativo na peça cirúrgica (p=0,03) foram estatisticamente associados à maior sobrevivência. CONCLUSÕES: A taxa de sobrevivência global estimada em cinco anos foi de 24,5%, com mediana de sobrevivência de 32 meses. O subgrupo de pacientes submetidos a cirurgias R0 em cujas peças cirúrgicas não foram encontrados invasão perineural vascular e/ou linfática nem linfonodos comprometidos apresentou taxa de sobrevivência estimada em três e cinco anos de 74,4% e 55,0%, respectivamente, com mediana de sobrevivência de 87 meses. Não houve diferença significativa entre pacientes que evoluíram com PD ou RD. Identificou-se a cirurgia R1-2, invasão perineural vascular e/ou linfática e linfonodo positivo na peça cirúrgica como fatores preditivos independentes de mortalidade / INTRODUCTION: The standard treatment for epidermoid carcinoma of the anus (ECA) is the association of chemotherapy (QT) and radiotherapy or exclusive radiotherapy (RT). When conservative treatment fails, patients are submitted to abdominoperineal resection of the rectum (APR). OBJECTIVES: To assess survival with salvage APR in ECA, identifying the most favorable independent descriptors for longer survival and the characteristics of the group of independent variables for mortality risk. METHODS: Data were collected from the medical records of 111 patients with ECA, initially treated with QT/RT or exclusive RT and later submitted to APR, from October 1982 to January 2011. RESULTS: Their mean age was 58 years, 93 (83.8%) patients were female, and 80 (72.1%) were Caucasian. The cT3-4 stage represented 66.7% of the case series and cN0, 39.6%. The APR was indicated due to persistence of disease (PD) in 61 (55%) patients and recurrence of disease (RD) in 50 (45%) patients. Surgical resection without residual tumor (R0) was performed in 86 (77.5%) patients. The mean postoperative hospital length of stay was 14 days. Surgical morbidity was 64.9%, of which, 78.3% related to perineal infection. Recurrence after APR was observed in 68 (61.2%) patients, 40 (58,8%; 40/68) of whom in the first postoperative year, mostly locoregional (78%; 53/68). The median follow-up was 16 months (1.2 - 60 months). On multivariate analysis, R0 surgery (p<0.001), absence of perineural and/or lymphovascular invasion (p<0.0001) and negative lymph node status in the surgical specimen (p=0.03) were associated with increased survival. CONCLUSION: Estimated overall survival rate in 5 years was 24.5%, with median survival of 32 months. There was no significant difference in survival after APR in patients who had PD or RD after conservative treatment. The subgroup of patients who underwent R0 and whose surgical specimen showed absence perineural and/or lymphovascular invasion and negative lymph nodes had an estimated survival rate at 3 and 5 years of 74,4% and 55,0%, respectively, with a median survival of 87 months. The following were identified as independent predictors of mortality: R1-2 surgery; presence perineural and/or lymphovascular invasion; and positive lymph node in the surgical specimen
