Three essays in applied economics

Tesei, Andrea 12 July 2012 (has links)
This thesis investigates different social and political aspects of modern economies. The first chapter contributes to the natural resource curse debate, by showing that the impact of resource windfalls is different among democracies and autocracies. The results also point to the existence of a large heterogeneity in the response to resource shocks among autocracies. The second chapter focuses on metropolitan areas in the US, and deals with the issue of social capital formation. I examine one important aspect of social capital, trust, and argue that it is lower when income inequality between different racial groups in the metropolitan area is higher. The third chapter studies the relation between media influence and electoral voting in Italy. I relate electoral outcomes at the municipal level to differences in signal reception of Silvio Berlusconi's private TV network. The results show that greater exposure to commercial television increases support for Silvio Berlusconi's party. / Aquesta tesi investiga diferents aspectes socials i polítics de les economies modernes. El primer capítol versa sobre el debat a l'entorn dels recursos naturals, mostrant que l'impacte dels guanys imprevistos dels recursos és diferent entre democràcies i autocràcies. Els resultats també indiquen l'existència d'una àmplia heterogeneïtat entre autocràcies en la seva reacció davant a variacions dels recursos. El segon capítol se centra en les àrees metropolitanes dels EUA i tracta el tema de la formació de capital social. He examinat un aspecte important del capital social, la confiança, i, argumento que és baixa quan, en la mateixa zona metropolitana, hi ha una gran desigualtat en les rentes dels diferents grups racials. El tercer capítol estudia la relació entre la influència dels mitjans de comunicació i el vot electoral a Itàlia. He relacionat els resultats electorals a nivell municipal amb les diferències en la recepció del senyal dels canals privats de televisió de Silvio Berlusconi. El resultat mostra que una gran exposició a la televisió comercial incrementa el suport polític al partit de Berlusconi.

Fair access to environmental justice in poor nations: case studies in Bangladesh

Ahmed, Farid January 2009 (has links)
The thesis is about environmental values that we encounter in our everyday life. The thesis also talks about environmental justice dialogues and tensions that play in Bangladesh. The thesis, in the first place, explores how an environmental planning and resource management approach causes a particular type of environmental injustice; i.e., non-recognition of access to the decision making process of local ethnic communities, which identifies them as adivasi meaning indigenous, poses a threat to their livelihood and culture, and obstructs the process of environmental protection in Bangladesh. / The existing theories of environmental justice and four case studies conducted in Bangladesh have been used to interrogate the research findings. I argue, along with Low and Gleeson (1998) that for environmental justice, recognition of environmental needs for every entity as an ingredient of human dignity should be basis of the planning process. The research findings also suggest that , at all levels of decisions, fair access to decision, information and justice for all entities should be an integral part of environmental planning and resource management. / The thesis explores avenues for fair access to justice, meaning redress and remedy of environmental injustice, in the context of Bangladesh. I argue that capillaries of justice such as Salish, a process and institution for public interest negotiation (PIN) embedded in Bangladesh culture, can be reinvented. In addition, access to information should be a prerequisite for meaningful deliberation at all levels of decision making and dispute resolving processes.

Soil erosion, deforestation and rural livelihoods in the Central Rift Valley area of Ethiopia: a case study in the Denku micro-watershed Oromia region

Kassu Kebede Beyene 06 1900 (has links)
This research was conducted in one of the districts in the Oromia region located in the Central Rift Valley to assess the problem of soil erosion and deforestation and to determine how these drivers of land degradation affect the livelihoods of farmers. The research was a case study undertaken in an identified micro-watershed making use of the questionnaire interview method. A household sample was obtained using a simple random sampling technique; Information interviews were conducted with community representatives, district level experts and development agents who worked in the community. The objective of the research was to assess the levels of soil erosion and deforestation and the impact on the livelihoods of the community. Research methods were questionnaire and direct observation. The results of the study indicated that the effects of soil erosion and deforestation on land productively, agriculture and livestock production at large, had a negative effect on livelihoods of the community members. Recommendations based on the research affirm the necessity to undertake large-scale natural resource management starting with community-based watershed management thereby reducing the impact of land degradation on livelihoods of farmers and ensuring food security and sustainable land management. / Agriculture, Animal Health and Human Ecology / M.A. (Human Ecology)

Poverty and environment : a case study of stone crushing as a sustainable livelihood in Lusaka

Nyumbu, Mutande Elizabeth 06 1900 (has links)
Poverty and the environment are closely linked, as people use environmental resources to support livelihoods. Illegal stone quarrying evident in Lusaka, Zambia is symbolic of the use of environmental resources by the poor. Stone crushing provides income yet it is characterized by land degradation, large-scale excavation and dumping of waste materials. This study provides an analytical account of stone crushing as a livelihood in Lusaka and makes recommendations for improving the livelihoods of stone crushers to become sustainable. Using a livelihoods approach, a qualitative study collected data from various role players in Lusaka. Assets (physical, natural, human, social and political capital) for stone crushers were assessed, revealing that stone crushers lack livelihood assets, key options and are exposed to various shocks due to seasonal shifts. Increasing access to key livelihood assets, reducing vulnerability, improving infrastructure, access to justice and tackling social exclusion and gender inequality will enhance their livelihoods. / Development Studies / M.A. (Development Studies)

Perceptions of local communities on legislation governing the use of natural resources in Coffee bay and Hole in-the wall, Mqanduli, Eastern Cape, South Africa

Mahlangabeza, Neliswa Joyce 03 1900 (has links)
The study was aimed at assessing perceptions of local communities on the use of coastal natural resources in Coffee Bay and the “Hole in-the Wall” area. The environmental impact caused by non–compliance with environmental legislation was also assessed. Data was obtained through interviews conducted with members of 50 households chosen randomly and questionnaires that were distributed to government departments in charge of the resources. The study found that due to high illiteracy and unemployment in the area, people were compelled to use the available coastal natural resources to satisfy their basic needs. About 70% of them were aware of the legislation but felt they could not comply with it since they had not been consulted. The study’s recommendations are that the community should be consulted on legislation, more environmental awareness campaigns should be conducted and government plans should be aligned in terms of service delivery / Environmental Sciences / M.Sc.

An evaluation of the potential for implementing adaptive co-management in the Waodani social-ecological system in the Ecuadorian Amazon

Bryja, Malgorzata Anna January 2015 (has links)
Adaptive co-management (ACM), one of the most prominent management approaches to emerge in the recent years, combines iterative learning, flexibility, and adaptation promoted by adaptive management with the principles of nurturing diversity and fostering collaboration among different partners that underpin co-management philosophy. ACM has been proposed as an approach to address the deficiencies of centralized management in ensuring sustainability of social-ecological systems (SESs) in face of future uncertainties. This thesis aims to evaluate the readiness of resource users (the Waodani) as well as external actors (the Ecuadorian State and NGOs) for future implementation of ACM and thus enhancing the long-term social-ecological sustainability of the Waodani SES located in the Yasuni Biosphere Reserve in the Ecuadorian Amazon. Qualitative data obtained by means of focus groups with the Waodani and individual interviews with external actors and Waodani leaders revealed different levels of readiness for ACM. Firstly, in the case of the Waodani, the insufficient fulfillment of some conditions required for successful ACM as well as intercommunity differences in regards to these conditions can complicate the implementation of ACM, unless sufficient external assistance is offered to the SES. The analysis of NGOs demonstrated, on the other hand, a relative readiness for ACM, providing that such aspects as sufficient funding, long-term commitment to collaboration, and inter-institutional linkages are strengthened. The study also found that the Ecuadorian government’s potential to contribute to ACM is hindered by the lack of readiness to work with the indigenous society as well as by funding and communication challenges. Furthermore, the resource based economy supported by the State limits the scope of innovation and adaptation. Still, as in the case of other actors, overcoming the challenges and transitioning towards adaptive governance and thus ACM could be possible in the long-term, if recent legal and political changes are truly implemented.

Evaluation of the performance of community-based natural resources management (CBNRM) projects along an aridity gradient in Botswana

Mpofu, Khulekani January 2013 (has links)
The Botswana Community Based Natural Resources Management (CBNRM) programme started in 1989. Its aims were to promote sustainable development through sustainable natural resources management and utilisation to improve rural livelihoods. The country CBNRM programme has recorded mixed outcomes and this has raised questions on the programme performance throughout the country. Since the programme has been recognised as one of the eight main livelihood strategies for rural communities in Botswana, there was a need to evaluate the programme performance and determine the factors that influence it. This thesis therefore evaluated the performance of CBNRM projects along an aridity gradient in Botswana and by so doing answered the two research questions of: (1) What factors influence the performance of CBNRM? And (2) how does aridity influence the performance of CBNRM programmes? Performance was determined in terms of financial benefits generated by CBNRM projects and the projects adherence to the CBNRM principles. Data were collected from seven selected CBNRM projects covering three aridity zones (wet, medium rainfall and dry areas) in the country. Data were also collected from key informants and community based organisations (CBO) project managers. Research findings have indicated differences in the performance of CBNRM projects across the identified three aridity zones. Factors that influenced the performance of CBNRM projects varied among the three aridity zones. These factors included: existence of complimentary rules and regulations for managing CBNRM projects; literacy levels of communities involved in CBNRM; ethnic composition of the project communities; historic and current socio-economic trends within communities; collaboration between CBNRM institutions and other local level institutes; amount of benefits generated through the projects; ability of institutions to resolve outstanding issues in time and type of CBNRM project. Research results also indicated that there was variation in the performance of CBNRM projects across the three aridity zones. Aridity was found to directly influence the performance of CBNRM projects through its influence on the amount of revenues that projects generated.

Stewardship in an urban world : Civic engagement and human–nature relations in the Anthropocene

Enqvist, Johan January 2017 (has links)
Never before have humans wielded a greater ability to alter and disrupt planetary processes. Our impact is becoming so noticeable that a new geological epoch has been proposed – the Anthropocene – in which Earth systems might no longer maintain the stable and predictable conditions of the past 12 millennia. This is particularly evident in the rapid expansion of urban areas, where a majority of humans now live and where environmental changes such as rising temperatures and habitat loss are happening faster than elsewhere.  In light of this, questions have been raised about what a more responsible relationship between humans and the rest of the planet might look like. Scholars in sustainability science employ the concept of ‘stewardship’ in searching for an answer; however, with multiple different applications and definitions, there is a need to better understand what stewardship is or what novelty it might add to sustainability research. This thesis investigates stewardship empirically through two case studies of civic engagement for protecting nature in cities – Bengaluru, India and New York City, USA. Further, the thesis also proposes a conceptual framework for how to understand stewardship as a relation between humans and the rest of nature, based on three dimensions: care, knowledge and agency. This investigation into stewardship in the urban context uses a social–ecological systems approach to guide the use of mixed theory and methods from social and natural sciences. The thesis is organized in five papers. Paper I reviews defining challenges in managing urban social–ecological systems and proposes that these can more effectively be addressed by collaborative networks where public, civic, other actors contribute unique skills and abilities. Paper II and Paper III study water resource governance in Bengaluru, a city that has become dependent on external sources while its own water bodies become degraded and depleted.Paper II analyzes how locally based ‘lake groups’ are able to affect change through co-management arrangements, reversing decades of centralization and neglect of lakes’ role in Bengaluru’s water supply.Paper III uses social–ecological network analysis to analyze how patterns in lake groups’ engagements and collaborations show better fit with ecological connectivity of lakes.Paper IV employs sense of place methods to explore how personal bonds to a site shapes motivation and goals in waterfront stewardship in New York City. Finally,Paper V reviews literature on stewardship and proposes a conceptual framework to understand and relate different uses and underlying epistemological approaches in the field. In summary, this thesis presents an empirically grounded contribution to how stewardship can be understood as a human–nature relation emergent from a deep sense ofcare and responsibility, knowledge and learning about how to understand social–ecological dynamics, and theagency and skills needed to influence these dynamics in a way that benefits a greater community of humans as others. Here, the care dimension is particularly important as an underappreciated aspect of social–ecological relations, and asset for addressing spatial and temporal misalignment between management institutions and ecosystem. This thesis shows that care for nature does not erode just because green spaces are degraded by human activities – which may be crucial for promoting stewardship in the Anthropocene. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript. Paper 4: Manuscript. Paper 5: Manuscript.</p>
