Since 1994 fundamental transformation has taken place in South Africa in terms of disaster risk management. The transformation process gave rise to the promulgation of the Disaster Management Act (57/2002) that heralded a new era for disaster risk management in South Africa. Consequently the National Disaster Management Framework, published in 2005, set clear guidelines for the implementing of the mentioned act. The National Disaster Management Framework emphasises the importance of the integration and coordination of disaster risk management activities in all spheres of government. Die Disaster Management Act (57/2002) calls for the establishment or certain disaster risk management structures like interdepartmental commitees, disaster management centers, disaster management frameworks, and disaster management advisory forums. Furthermore the National Disaster Management Framework sets certain guidelines in compliance with the Disaster Management Act (57/2002). Municipalities in South Africa have had time since the promulgation of the act in 2003 to get all the mentioned structures in place. This study tried to deretmine the degree in which municipalities complied with the requirements of the Disaster Management Act (57/2002). The municipalities were handles per procvince and the research is based on a 20% representative sample of all the municipalities in South Africa. A mixed method of research was followed. That means that qualitative (telephonic and semi-structured interviews) and quantitative (questionnaires with Likert scale questions) research was used. The result of this research is that there are big failings in terms of the implementing of the Disaster Management Act (57/2002) across the country. In certain provinces the situation is better than in others, but of none of the provinces it can be said that they comply with all the recuirements of the act. / M.

Socioeconomic study is a procedure that ensures that the likely positive and negative impact of a new project on the socioeconomic life of a community is taken into account. It has become a crucial part of sustainable development process. The understanding of socioeconomic study procedures is an increasing necessity for all those involved in the process. Similarly, proper knowledge of the function of socioeconomic study during the environmental impact assessment (EIA) process is of paramount importance for the mitigation of the likely effects of the new development. Furthermore, as the world is gradually growing into a global village, it has become increasingly imperative that organizations integrate the people in their operations' areas in the overall objective of their businesses. Community engagement (CE) is a partnership process that can be used to assess and manage the problem affecting the well-being of a community because of a new development. This research work used the SWOT matrix technique to develop a management framework that companies can use to manage their weaknesses and threats because of inadequate community engagement strategy. To achieve this, the work evaluated the extent to which socioeconomic study is integrated into the EIA processes. It also assessed the extent to which oil companies are using community engagement as a development strategy. The findings of this dissertation revealed that oil explorations in the Niger Delta area have affected the well-being of the people both positively and negatively. Unfortunately, their negative impact outweighed their positive impact. Although they carry out socioeconomic studies, they have been neglecting the recommendations reported in the socioeconomic study document by experts. The level of community engagements therefore has also been very poor. SWOT matrix technique was used to develop the management framework for each company based on the perceived strengths, weaknesses, opportunities and threats of the companies as revealed in this research. This should serve as a guide for the companies in their CE strategies. / Thesis (M.Ing. (Development and Management Engineering))--North-West University, Potchefstroom Campus, 2009.

Although disaster risk reduction is still not considered a priority by many countries and organisations, there is significant progress made towards the reduction of disaster risk. The experience of the International Decade for Natural Disaster Reduction (IDNDR, 1990–1999) prompted a major conceptual shift from disaster response to disaster reduction underscoring the crucial role of human action (UNISDR, 2001:03). This circumstance led to the adoption of an International Strategy for Disaster Risk Reduction (ISDR) in 1999 by the participants of the IDNDR Programme Forum. The adoption gave emphasis to the importance of a global strategy that encourages and facilitates concerted action to reduce risk and vulnerability to natural and related technological and environmental hazards. This research then focuses on the disaster risk reduction phenomenon and major or international initiatives and forums aimed at improving or raising the disaster risk reduction profile. It also focuses on disaster risk management in the South African context. In recent years, disaster risk reduction has grown in importance on the international agenda. This followed the prevalence of natural hazards such as floods, drought, earthquakes, tsunamis, as well as epidemics, which have had an increasing impact on humans, due to population growth, urbanization, rising poverty and the onset of global environmental changes. Aspects of environmental change include climate change, land degradation and deforestation. Practitioners and researchers widely acknowledge that poor planning, poverty and a range of other underlying factors create conditions of vulnerability that result in insufficient capacity or measures to reduce hazards‘ potentially negative consequences (IISD/UN/ISDR, 2007:01). It is in this light that in 2005 many governments around the world committed themselves to take action to reduce disaster risk, and thereby adopted a guiding document to reduce vulnerabilities to natural hazards, called the Hyogo Framework for Action (HFA). The HFA was adopted in January 2005 at the World Conference on Disaster Reduction, in Kobe Hyogo, Japan by 168 States. The aim of the HFA is to assist the efforts of nations and communities to become more resilient to, and cope better, with the hazards that threaten their development gains with the overriding goal of achieving a substantial reduction in global disaster risk. It also emphasizes that disaster risk reduction is a central issue for development policies, in addition to being of interest to various science, humanitarian and environmental fields. To help attain the expected outcome, the HFA identified five specific priorities for action (PFAs) which are: (i) making disaster risk reduction a priority; (ii) improving risk information and early warning; (iii) building a culture of safety and resilience; (iv) reducing the risks in key sectors; and (v) strengthening preparedness for response. The Global Network of Civil Society Organisation for Disaster Risk Reduction (GNDR) which was launched in 2007 in Geneva, is a major international network of civil society organisations working to influence and implement disaster risk reduction policies and practice around the world. The major programme of the global network is to collect perspective for the local level as to how the HFA is progressing. The Views from the Frontline (VFL) is the first independent assessment project undertaken towards the implementation of the HFA at the local level and is led by the Global Network. The aim of this project is to measure the gap between policy formulation at international level with the realities of policy execution at local level and to deepen the communication and coordination between different stakeholders on disaster risk reduction by involving government organisation and communities at the local level. The VFL perspective is that nationally formulated policies are not generating widespread systematic changes in local practices. There is a concern that the current approach is top–down and engages minimally with affected communities and fails to address their needs and capacities (GNDR, 2008:01). The main objective of this research was to provide an overview of progress made in the implementation of the HFA at local level particularly in the Kabokweni Location. The approach adopted in this study is called 'the Views from the Frontline', and explores the extent of the actual progress made toward the implementation and impact of the HFA priorities at local level, namely the Kabokweni community in the Mbombela Local Municipality (MLM) situated in the Mpumalanga Province of South Africa. / Thesis (M.

The Lower Athabasca Water Management Framework limits water extractions by the oil sands industry near Fort McMurray, Alberta. To increase water-use efficiency and minimise the cost of water restrictions, several policy and technology options were developed and assessed using quantitative and qualitative methods. Selected options were the policies of water trade and pricing with refund, and the technologies of storage, and consolidated tailings and increased recycling. Options were designed based on year 2020 demand and assessed relative to prior allocation. Using linear programming and static optimisation, it is shown that an off-stream storage sized to avoid water restrictions, in combination with efficient water allocation (e.g. water trade), is most cost-effective, although provides no ongoing incentive to increase water-use efficiency. Only the policy options provide equal incentives across firms to increase efficiency. To achieve both objectives of increased water-use efficiency and minimised costs, a combined policy and technology approach is recommended. / Agricultural and Resource Economics

The effective use of GPUs for accelerating applications depends on a number of factors including effective asynchronous use of heterogeneous resources, reducing data transfer between CPU and GPU, increasing occupancy of GPU kernels, overlapping data transfers with computations, reducing GPU idling and kernel optimizations. Overcoming these challenges require considerable effort on the part of the application developers. Most optimization strategies are often proposed and tuned specifically for individual applications. Message-driven executions with over-decomposition of tasks constitute an important model for parallel programming and provide multiple benefits including communication-computation overlap and reduced idling on resources. Charm++ is one such message-driven language which employs over decomposition of tasks, computation-communication overlap and a measurement-based load balancer to achieve high CPU utilization. This research has developed an adaptive runtime framework for efficient executions of Charm++ message-driven parallel applications on GPU systems. In the first part of our research, we have developed a runtime framework, G-Charm with the focus primarily on optimizing regular applications. At runtime, G-Charm automatically combines multiple small GPU tasks into a single larger kernel which reduces the number of kernel invocations while improving CUDA occupancy. G-Charm also enables reuse of existing data in GPU global memory, performs GPU memory management and dynamic scheduling of tasks across CPU and GPU in order to reduce idle time. In order to combine the partial results obtained from the computations performed on CPU and GPU, G-Charm allows the user to specify an operator using which the partial results are combined at runtime. We also perform compile time code generation to reduce programming overhead. For Cholesky factorization, a regular parallel application, G-Charm provides 14% improvement over a highly tuned implementation. In the second part of our research, we extended our runtime to overcome the challenges presented by irregular applications such as a periodic generation of tasks, irregular memory access patterns and varying workloads during application execution. We developed models for deciding the number of tasks that can be combined into a kernel based on the rate of task generation, and the GPU occupancy of the tasks. For irregular applications, data reuse results in uncoalesced GPU memory access. We evaluated the effect of altering the global memory access pattern in improving coalesced access. We’ve also developed adaptive methods for hybrid execution on CPU and GPU wherein we consider the varying workloads while scheduling tasks across the CPU and GPU. We demonstrate that our dynamic strategies result in 8-38% reduction in execution times for an N-body simulation application and a molecular dynamics application over the corresponding static strategies that are amenable for regular applications.

This study sets out to address problems caused by the lack of an integrated tourism management framework that would give a strategic direction to the delivery of tourism services in the Kruger National Park (KNP). The lack of tourism management plans and capacity in protected areas can be traced back to the classic management approach that concentrates exclusively on biodiversity conservation while paying superficial attention to other equally important management elements such as tourism, community participation, financial viability and governance matters. As a result of such management deficiencies, protected areas are unable to raise sufficient revenue from their tourism business to adequately meet obligations of their conservation mandate, community expectations and maintenance of the tourism facilities. Financial problems lead to over-dependence on diminishing and inflation-eroded state subsidies, thus compromising the effective management of parks. A management approach that does not balance the elements that constitute the management function of a protected area has the potential to destroy the resource base on which the attractiveness of a protected area as a holiday destination hinges and risks alienating tourists. The practice of 'fortress conservation' with protected areas treated as distinct units from their surrounding communities is being challenged worldwide. Protected area managers are now constantly looking for management paradigms that can harmonize the fundamental functions of conserving biodiversity, delivering tourism services and ensuring financial viability whilst contributing to the socio-economic development and benefits for local people balancing conservation and socio-economic needs. This is the situation in which the KNP finds itself. The study recommends the adoption of an integrated tourism management framework based on adaptive tourism management principles to enable the Park to cope with continuous uncertainties, conflict management, dynamic systems of societal changes, economic changes, changes of ecosystems and bridging the gap between conservation and tourism. / Thesis (PhD (Tourism Management))--University of Pretoria, 2005. / Tourism Management / unrestricted

With population growth and climate change issues, cities will face social, economic and environmental challenges. They are accountable for most of the energy consumption and GHG emissions, and the building sector represents roughly 40% of the final energy consumption worldwide. Still, cities transform by renewing or creating districts, which design comes with specific engineering and management methods. Simulations tools at district scale might lead to more sustainable urban development by considering phenomena at such scale. Energy, microclimate and aeraulic simulations are performed on two study cases from real estate projects in France. This thesis investigates whether the tools allow to unlock new development strategies, and which engineering and management frameworks they require. The benefits for urban planners and architects are discussed, and the replicability of the tools is assessed. The studies also provide academic knowledge, beneficial to the actors for qualitative analyses. The energy needs and potential of energy sharing are assessed. Sensitivity analyses on design characteristics such as windows or insulation provide insight on their respective impacts on energy needs and sharing. The microclimate and heat island effects in the district are investigated, thanks to the evolution of air temperature and comfort index PET, bringing knowledge on the effects of trees and buildings. The winds within several urban plans are also simulated, providing insight on comfort in the district as well as academic experience on the relations between architecture and winds. Those studies therefore provide assessment and recommendations for the district, as well as knowledge for future qualitative and quantitative analyses. Plus, modeling and management issues and their resolutions help to construct a framework to improve the efficiency of such studies in terms of time, and therefore cost. Eventually, a simplified aeraulic study tests the engineering and management frameworks. Finally, conclusions present the design strategies and the management requirements to replicate such studies. / Med befolkningstillväxt och klimatfrågor kommer städerna att möta sociala, ekonomiska och miljömässiga utmaningar. De är ansvariga för de flesta av energiförbrukningen och växthusgasutsläppen, och byggsektorn utgör ungefär 40% av den slutliga energiförbrukningen. Ändå, transformerar städerna genom att förnya eller skapa distrikt, vilken design kommer med specifika ingenjörsmetoder och hanteringsmetoder. Simuleringsverktyg i distriktskalan kan leda till en mer hållbar stadsutveckling genom att överväga fenomen i sådan skala. Energi, mikroklimat och aerauliska simuleringar utförs på två studiefall från fastighetsprojekt i Frankrike. Denna maggisteruppsats undersöker om verktygen tillåter att låsa upp nya utvecklingsstrategier, och vilka tekniska och ledande ramar de behöver. Fördelarna för stadsplanerare och arkitekter diskuteras, och verktygets replikerbarhet bedöms. Studierna ger också akademisk kunskap som är till nytta för aktörerna för kvalitativa analyser. Energianvändningen och potentialen för energidelning utvärderas. Känslighetsanalyser på designegenskaper som fönster eller isolering ger insikt om deras respektive inverkan på energibehov och delning. Mikroklimat och ”värme ö effekter” i distriktet undersöks tack vare utvecklingen av lufttemperaturen och komfortindex PET, vilket ger kunskap om effekterna av träd och byggnader. Vindarna inom flera stadsplaner simuleras också, vilket ger insikt om komfort i distriktet samt akademisk erfarenhet av relationerna mellan arkitektur och vindar. Dessa studier ger därför bedömning och rekommendationer för distriktet, samt kunskaper om framtida kvalitativa och kvantitativa analyser. Dessutom, modellerings- och hanteringsfrågor och deras resolutioner bidrar till att konstruera en ram för att förbättra effektiviteten av sådana studier i form av tid och därmed kosta. Så småningom tester en förenklad aeraulisk studie av konstruktions- och förvaltningsramarna. Slutligen presenterar slutsatserna designstrategierna och förvaltningskraven för att replikera sådana studier.
