Its main objectives are guarantee that the future public hea1th and safety are not compromised; environmental resources are not subject to further physical and chemical deterioration; the post-mining use of a site is beneficial and sustainable in the long-tenn; and any adverse socio-economic impacts are minimized. The concepts and principIes surrounding mine closure are rapidly evolving in tenns of the supposed scope and responsibility of the major interested groups, among them government, industry, impacted communities and other stakeholders such as non-governmental organisations (NGOs), financial institutions and other components of civil society. The Law - as a social science - has highlighted the society conscious and preoccupation with the proper and safe mine closure and intemalized the best practices to achieve its purposes. This thesis focuses in the study and analysis of the evolution of mine closure art - under its several aspects. Highlight the economic and social importance of mining, through the analysis of positive and negative aspects of this human activity. Mine closure is introduced as new stage of the mining project. It is presented the concepts of some tenns usually employed in studies related to mine closure. Emphasize the main causes that can direct to closure, the types of closure that can occur and the steps part of this processo The main environmental, economic and social impacts from the mine closure process are analysed. Deal with technical, legal, social and environmental aspects in the law of some selected countries. Synthesize mine closure regulation in the Brazilian Law. Approach the programmes in course for closure of some small, medium and large size Brazilian mines. At the end recommends some points inherent to mine closure as suggestions to future researches and presents, as an appendix, a proposal of guidelines as a contribution to the study and the progressive regulation on mine closure in Brazil / Doutorado / Administração e Politica de Recursos Minerais / Doutor em Ciências

Carbon Offsetting, a new form of CO2lonialism? : Local implications of tree-planting projects in East Africa / Klimatkompensation, en ny form av CO2lonialisering? : Sociala effekter av trädplanteringsprojekt i östra Afrika

Larsson, Cecilia, Orvehed, Moa January 2021 (has links)
Carbon offsetting has a growing presence on the global climate action agenda where it is promoted as a triple-win for the environment, business and development. However, the opinions on carbon offsetting are divided. Projects with agroforestry and participatory methods are highlighted as having more positive aspects, but critics emphasize that carbon offsetting can become an excuse for the Global North to continue business as usual while using the Global South as a carbon dump. Carbon offsetting can reproduce unequal power structures where countries, while formally decolonized, are still affected by coloniality. This study examines carbon offsetting through tree planting projects and the potential discrepancies between discourse and documented effects in East Africa with focus on Uganda. Four projects are compared with each other, focusing on documented social effects and impacts on land access. We analyze how power structures are expressed in carbon offsetting generally and in the projects. This is a literature study with a combined theoretical framework of political ecology and the decolonial approach. Findings imply that there, to varying degrees, are discrepancies between rhetoric and reality for the projects. Differences between the projects’ outcomes mainly boil down to their planting method, degree of participation and operating logic. All the projects are to varying degrees based on a coloniality, permeated by power structures and have some level of exclusion. However, findings also imply that best practices involve the local communities in a bottom up approach with an agroforestry method and carbon offsetting as a co-benefit.

Ekonomické a sociální dopady kulturního cestovního ruchu v ČR / Economic and social impacts of cultural tourism in the Czech Republic

Raabová, Tereza January 2006 (has links)
The work observes the positive relationship between culture and tourism and quantifies the economic and social (or socio-economic) impacts of cultural tourism in the Czech Republic. The first part showcases successful cultural projects in the Czech Republic and abroad, which attract tourists and provide destinations with financial resources and create new jobs. The author characterizes these positive economic and social impacts and benefits on the development of the region and analyzes existing studies of socio-economic impacts, normally processed abroad for cultural organizations and attractions. While in the Czech Republic, these studies are not yet very widespread, they represent a a useful document for the organization itself, but also for providers of grants and financial contributions, or for agencies and authorities designing concepts of culture and tourism. The work presents the basic methodologies used by the economic impact studies and further elaborates the most accurate and also the most demanding method of calculating the impacts, input-output analysis. Using this method, the author proposes a comprehensive model for calculating the economic and socio-economic impacts and benefits. The model uses statistical data of Czech national accounts and is intended for Czech cultural organizations attracting visitors. After using financial data of the surveyed organization and the expenditure of visitors, the model can easily determine the impacts of the organization to increase production, gross value added, employment and income of workers in the Czech Republic. The work builds on a lot of foreign findings, which seeks to apply in domestic conditions while using local data.

A complex systems perspective on communities and tourism : a comparison of two case studies in Kaikoura and Rotorua

Horn, Chrys January 2002 (has links)
This thesis analyses research into the evolution and adaptation of the communities in Rotorua and Kaikoura by using a complex systems perspective. This perspective requires that the analyst look beyond the obvious impacts of tourism such as employment, crowding, and congestion, to the processes that underlie the experiences of local people in relation to tourism. The configuration of the destination, the flows of people in the area, the visitor types and the ratio of hosts to guests all influence a community's interactions with tourists. In small destinations, the effect of host interactions with guests is potentially much greater than is the case in larger destinations. However, in using a complex systems perspective to analyse the effects of tourism on these two destinations, it becomes clear that the impacts of tourism are more than just the impacts of tourists. The impacts of tourism are intertwined with the processes of trust, leadership and decision making occurring both within the community and within the wider regional and national socio-economic systems. As such, local perceptions of tourism are associated with history, geography, local politics and local social processes. As concepts, the meanings of both 'tourism' and 'community' emerge from the experiences people have, and the associations that they make with the two terms. Thus, the meaning of both 'tourism' and 'community' are idiosyncratic and locally defined. Each term means different things to residents in Rotorua and Kaikoura, and each affects how residents perceive tourism in their respective towns. For example, the associations that people make between historical events and processes such as restructuring are quite different in each of the two communities. In Rotorua, tourism is seen as a source of stability, as a phenomenon that confers a higher level of perceived control on the community. In Kaikoura, tourism is seen as a source of change and it confers a lesser sense of perceived control on the community overall. Likewise, the relationship between the local council and the community underlies the sense of security people feel about local decision making processes. This relationship is mediated by a range of processes including the effort that the council put into communicating with community members, the leadership shown by the council, the way in which they facilitate community visioning processes, which then provide a basis for both leadership and decision making. Underlying these processes are community processes of rivalry, competition, cooperation, labelling and stereotyping that all affect the levels of trust that the community have in those around them. Community cohesion (which is not the same as community agreement) underlies a community's ability to work together to manage tourism. Thus using a complex systems approach to analyse the impacts of tourism in two destinations has shown that there is much more to tourism than the impacts of tourists and their activities. Instead, the way the community system interacts with the tourism system gives rise to the impacts of tourism. Tourism can be usefully conceptualised as a process that is inextricably interwoven with history, politics and community interaction processes at the destination level. Perceptions of tourism reflect these processes and the understanding that local people have of them, and the level of control that they feel they have over tourism development. With little trust in local decision making processes, people have a low sense of control over how tourism development affects them. In tourism planning, therefore, it may be more effective to focus primarily on the processes by which tourism development and management occurs in the local area and to look at mitigating the effects of tourists only after building community capacity to adaptively manage tourism in their area. Communities need a sense of control over their world, and this is only undermined when experts and institutions try to advise courses of action without involving a range of community players in the process of managing tourism. Thus, government and other organisations and institutions at local level must focus on working with communities to build local capacity to manage tourism, without imposing on those communities to convince them to 'treat tourists well' or to manage their environment better, so they become more attractive as a destination.

Is the salmon farming industry externalizing its social and ecological impacts?: an assessment using the Global Aquaculture Performance Index.

Gee, Jennifer L. M. 29 April 2010 (has links)
Neoliberal economists argue that the market provides the most efficient mechanism to address externalities. Theoretically then, the market value of a commodity should show a correlation with any changes in social and ecological performance. Alternatively, if the social and ecological costs of production are being externalized (not addressed by the market) then it is expected that the social and ecological costs of production would not be reflected in the market price. This study examined the extent to which social and environmental costs are externalized by the salmon farming industry and, by extension, to what level social and ecological impacts are reflected in the market, if at all. The salmon farming industry represents a classic example of how a relatively new industry functions within the confines of the current economic climate and was assessed to examine whether social and ecological impacts are reflected in the market. A novel tool called the Global Aquaculture Performance Index (GAPI) has been developed that addresses both the need for a quantitative measure of social and ecological performance and a tool that informs where policy is best directed to alleviate the impact of externalities. In applying the GAPI method, the market price for farmed salmon was not found to be correlated with changes in social and ecological performance and it may be assumed that these costs are externalized. GAPI provides a quantitative, performance based assessment of the salmon farming industry while the indicators of social and ecological performance provide clear starting points to improve salmon farming through a policy based context.

Sustainable Renewable Energy Policy on Energy Indicators, Electric Power and Renewable Energy Supply Chains. A study of renewable energy policies, energy indicators and electrical power distribution

Owaka, Smart O. January 2020 (has links)
Due to the result of the sudden fossil fuels over-night price rises of 1973/1974, coupled with the depletion of the traditional energy resources, many initiatives globally have addressed the efficient use of these resources. Since then, several renewable energy sources have been introduced as alternatives to traditional resources to protect environmental resources and to improve quality of life. Globally, there are more than a quarter of the human population experiencing an energy crisis, particularly those living in the rural areas of developing countries. One typical example of this is Nigeria. This is a country with approximately 80% of her population consistently relying on combustible biomass from wood and its charcoal derivative. Nigeria has an abundant amount of both renewable and fossil fuel resources, but due to the lack of a reasonable energy policy (until recently), it has concentrated on traditional fossil fuels alone. Renewable energy is now Globally considered as a solution for mitigating climate change and environmental pollution. To assess the sustainability of renewable energy systems, the use of sustainability indicators is often necessary. These indicators are not only able to evaluate all the sustainability criteria of the renewable energy sources,1 but also can provide numerical results of sustainability assessment for different objective systems.

The social sustainability of the Table Mountain cableway

Deysel, Valencia 08 May 2014 (has links)
Social sustainability provides a meaningful approach for industry practitioners wishing to establish a platform to engage communities within enterprise development. It can be said that sustainability requires much more than environmental and fiscal achievements and, with an increased awareness of issues such as equity and power sharing, more corporates are incorporating their strategies in line with social responsibility values. This study therefore takes a closer look at how the Table Mountain Aerial Cableway Company, integrates this important concept of social sustainability in its business practices. The tourism industry has in fact grown to such an extent that global economists estimate the progress of international growth at between three and six percent annually. However, this growth can only be measured when businesses take social responsibility factors into consideration. According to the UNWTO (2011, p 1) UN Secretary-General, Ban Ki-Moon, opened the Fourth UN Conference on Least Developed Countries stating that the majority of: “…least developed countries (LDCs) are rich in resources. All have young and vibrant populations. These men and women need decent jobs, education, training, so they can make the most of their country’s assets - minerals and other commodities, farmland, rich stores of biodiversity and tourism potential”. This study therefore focuses on current and future issues pertaining to socially sustainable tourism at the Table Mountain Aerial Cableway Company in Cape Town, South Africa. In addition, it presents solutions for reducing the negative impacts of tourism, whilst at the same time embracing the benefits of tourism for the area and its local communities. The outcome of the study found that the Table Mountain Aerial Cableway Company added little value to social responsibility objectives. The company has made a significant effort in marketing their product through the mass media. However, there is an overall corporate responsibility barrier. Much still needs to be done to ensure accountability for social responsibility issues, not just within this particular company, but also throughout the tourism industry. / Environmental Sciences / M.
