Evaluating ‘Just Transition’ policies for coal workers in Alberta, Canada
I do not have current funding for additional graduate students or post-doctoral scholars but am generally interested in modeling of energy access in developing countries, assessment of socio-ecological linkages in energy use, household choice and welfare implications related to energy use, and synergies and tradeoffs in meeting sustainable development goals in forestry, energy and land-use.

Almost 40% of the global population relies on fuelwood to meet their daily cooking energy needs, accounting for over 50% of all wood extracted in many developing countries. This dependency can have negative impacts on forest stocks and climate change, and is not expected to decline without a major change in current polices. Consequently, there is a need for improved understanding of fuelwood dependency to both inform the transition to cleaner cooking solutions and for sustainable management of local forest resources to ensure supply for dependent communities in the interim. This requires a careful analysis of the long-term management of local forest and agroforestry resources, the particular fuel collection habits of local populations, and the impact of new cooking technologies and fuels on fuelwood consumption. However, understanding biomass extraction and its impacts on forest resources remains under-developed in comparison to demand-side issues of fuelwood consumption. I fill these gaps by first tracking household fuelwood collection behavior in two regions of India. The patterns indicate that fuelwood collection is a function of both socio-economic drivers and the resource base, and collection is not evenly spread out among villages. Next, I demonstrate the need to develop local level estimates of biomass renewability to isolate household fuelwood collection impacts on local forest resources. Then, I estimate the impact of cooking solutions on fuelwood consumption behavior and the circumstances under which households move away from forest fuelwood sources. Finally, I examine a national level transition to clean cooking in India over ten years, and conclude that it reduced pressure on forests and achieved modest climate change mitigation benefits with some uncertainty due to the extent of biomass renewability and inclusion of differing climate-forcing emissions. Overall, the dissertation elucidates the need for local level estimates to isolate household fuelwood extraction impacts on forests and climate change, and the need to carefully consider spatial scale and included emissions in future analyses and policy-making.

Producer participation in markets, including modernized food value chains (MFVCs) and conservation programs like payments for environmental services (PES), is promoted for both human development and environmental sustainability. Participation can benefit farmers but there are concerns that limiting producer choice and concentrating power with intermediaries could have negative consequences for wellbeing and sustainability. PES and MFVCs have similarities for participating producers, suggesting scope for cross-pollination and insight. However, the literatures remain largely separate, tend to consider a narrow set of indicators, and produce mixed results.This dissertation explores the following questions in the case of dairy farmers in Costa Rica: (1) How and when can producer participation in intermediary-driven food and environmental value chains lead to positive outcomes for wellbeing and sustainability? (2) How and when is it useful to consider PES and food value chains together? Using statistical and qualitative methods with 217 household surveys and 23 key informant interviews, this dissertation assesses how indicators of human wellbeing, broadly conceived, and agricultural practices differ between farms supplying MFVCs versus traditional dairy value chains, and between those who are and are not participating in PES. Chapter 2 uses an adaptive capacity framing to show that Costa Rican producers selling in MFVCs were likely better equipped to manage change than those selling in traditional markets. Chapter 3 provides evidence that wellbeing in MFVCs also varied between value chains: those selling via a multinational cooperative appear substantially better off than those selling to a private processor. Chapter 4 presents evidence that PES participants experienced limited material wellbeing benefits from participation; rather, values appeared to be an important motivator for many. Chapter 5 examines correlations between the use of more sustainable agricultural practices and participation in MFVCs and PES. MFVCs appear to be a stronger force than environmental values in shaping farm management choices. This dissertation highlights the value of a broad approach to wellbeing that considers non-material benefits and motivations alongside material ones. Considering Costa Rican PES and dairy market participation together highlights intermediaries and producer-intermediary relationships as important in influencing human and environmental outcomes when farmers participate in MFVCs and PES.
More than one-third of the world’s population has inadequate access to modern energy services and suffers as a consequence. A better understanding of energy transition is vital for improving future programs. This thesis investigates the challenges of transitioning to modern energy services with the goal of informing policy-making. Chapter 2 is a review of the literature on energy analysis and energy system uptake by the households with a particular focus on rural regions. Building upon the findings in the literature, a new conceptual framework is developed that can act as a basis for developing new empirical and theoretical models of household energy system uptake and use. In Chapter 3, the private sector based approach to rural energy provision (i.e. electrification and Improved Cookstove (ICS) dissemination) is investigated by examining two enterprises in India. Results indicate that the private sector based approach to rural energy provision cannot be a universal solution. It further shows that enterprises are facing many challenges that are beyond their capacity to address, necessitating alternate approaches to private sector involvement.Chapter 4 and 5 investigate the uptake of ICS by commercial kitchens in Bangalore and its potential health implications. The attributes of ICS and Liquefied Petroleum Gas (LPG) stove, as perceived by stove users and owners, are explored and the reasons for purchasing ICS are assessed. Results indicate that both groups mostly prefer LPG stoves and that ICS uptake is mainly motivated by economic factors. The potential health implications of this switch in the commercial kitchens are explored by investigating the stove’s emission characteristics (based on both secondary data and direct emission measurements), the stoves smokiness (as perceived by users and owners); and some health symptoms associated with stove smoke. Uptake of ICS by these commercial kitchens is found to potentially have adverse health implications. In brief, this thesis concludes that rural energy provision policies can be improved through a greater emphasis on the human dimension, comprehensive assessment of the target population, and ongoing evaluation of the programs’ outcomes given the major challenges in improving rural energy access and possibilities for spillovers into other market segments.
This thesis examines in-stream tidal energy (ISTE) generation technology and its potential for development, underwater within Discovery Passage, a narrow channel ocean environment near Campbell River, British Columbia, Canada. The study took place in the summer of 2014 and measured levels of support and opposition towards two separate investigative license (IL) ocean energy sites held by a BC developer. The primary approach was to interview expert marine stakeholders and First Nations persons based on their commercial, recreational and cultural usage of the Discovery Passage waterway and its foreshores near the ILs. The study measured subjects’ risk and benefit perceptions of the technology and the projects, levels of support for its development, willingness to pay for it, and any specific conflicts with the developments, both on and under the water. Interactive marine spatial planning (IMSP) and geographic information systems (GIS) were used to elicit respondents’ principle areas of marine usage within the study area, levels of value associated with these areas and seasons of usage. In addition, at the end of the interview, subjects were shown the IL sites on a map and were given the opportunity to indicate areas of perceived conflict between their organizations’ operations and the sites. Results found respondents to be initially strongly in favour of developing tidal energy in BC, with 88% indicating a high levels of support for its development and willingness to pay small amounts for it as part of BC Hydro’s rate increases. However, once the IL sites were shown to the interviewees specifically on a map, levels of support declined and specific opposition to the sites was identified amongst 72% of respondents, indicating highly localized risk perceptions towards the projects. Perceived risks identified by stakeholders included marine traffic interference stemming from installation operations, high costs, cumulative impacts of many turbine installations and tugboat towlines and fishing gear potentially snagging underwater turbines. Identified benefits of tidal energy included local reservoir water conservation from tidal energy generation displacing hydropower water use, local economic development, displacing regional area off-grid diesel generation and achieving more localized electrical generation on Vancouver Island.
Land scarcity and food insecurity are critical concerns for billions of individuals worldwide; voluntary resettlement, as a type of land reform, offers governments and aid agencies a controversial approach to address these concerns. This thesis examines the case of a US$38-million World Bank-funded voluntary resettlement scheme in southern Malawi known as the Community Based Rural Land Development Project, through which 15,000 low-income farming households moved internally from densely populated areas to underutilized plantations between 2004 and 2011. The project and its explicit goals (to increase participant income and agricultural productivity) have been the subject of several studies, but the wider range of indirect outcomes and possible unintended consequences are lesser known, which this thesis works to address. The first analytic chapter assesses the extent to which the project was ‘voluntary’, and considers the real versus perceived land tenure claims established by the programme. To enhance understanding this analysis, this chapter also considers factors influencing household participation and withdrawal in the resettlement. Quantitative and qualitative analysis of surveys (N=203), focus group discussions (N=5) and interviews (N=20) suggest that participants did not have a clear understanding of the project conditions, and that they perceived their new ownership rights to be more secure and individual than they were by law. Additionally, attrition rates were analyzed: despite numerous influences factoring into participant decisions to withdraw and return ‘home’, availability of land in the district of origin and access to infrastructure in the district of resettlement played significant roles. The second analytic chapter assesses the effectiveness of voluntary resettlement in improving food security, including its effects on dietary diversity. Regressions and statistical analyses of Dietary Diversity Scores indicate that participants had statistically significant lower levels of food security and dietary diversity than former and non-beneficiaries, possibly due to a lack of infrastructure and access to markets. These findings highlight the importance of participatory holistic planning for voluntary resettlement, particularly to ensure participant understanding of future living conditions, and ultimately challenge the utility of voluntary resettlement as a policy tool to improve the well-being of subsistence farmers.
Climate change is a serious global problem that will have a disproportionate impact on developing countries. The ability of these countries to cope depends, at least in part, on the strength of their human capital and institutional capacity related to climate science. This thesis begins by examining the extent to which developing country scientists are participating in global climate science, and then evaluates international efforts to build the capacity of developing country scientists to address the climate change problem. A quantitative analysis of authorship data of the United Nations Intergovernmental Panel on Climate Change (IPCC) assessment reports (1990, 1995, 2001 and 2007) reveals that developing country scientists and institutions remain grossly under-represented – even after normalizing for a number of factors. The IPCC has recently acknowledged this ongoing problem, while the international community has resolved through the United Nations Framework Convention on Climate Change (UNFCCC) process to prioritize capacity building in developing countries. Extensive open source research and interviews with key informants at leading international organizations were used for qualitative purposes to identify, analyze, and evaluate such capacity building efforts. While several impressive initiatives were identified at the regional level, most capacity building activity was isolated and likely to be of limited effectiveness in advancing concerted global action to mitigate and adapt to climate change. The overall conclusion is that the existing international approach to building scientific capacity in the developing world to address climate change is inadequate. Several significant obstacles to achieving sustainable, long- term scientific capacity to address climate change in developing countries are explored, including: institutional barriers, financial issues, the “brain drain” phenomenon, data access and quality, technology and research resource limitations, complexities with downscaling/up-scaling of climate modeling, the interdisciplinary nature of climate change, navigating the science-policy interface, and issues related to operating across culture, language, and gender. Finally, this thesis concludes that the largely ad hoc approach to individual capacity building activities should give way to a more comprehensive, integrated, strategic approach to more effectively build scientific capacity in the developing world to meet the climate change challenge.
‘Improved’ cooking technologies, which in general are cleaner burning with higher levels of complete combustion, greater efficiency and better heat transfer then less-efficient cooking technologies, have been generally understood in the global community to be a ‘win-win’ development intervention creating a multitude of benefits. Yet as in most environment-development efforts there are many unacknowledged tradeoffs that exist under the all-encompassing ‘win-win’ claims. In this study tradeoffs made between two co-benefits of cookstove projects, climate and health, are examined under the framework of carbon financing mechanisms. Two methodologies used to calculate carbon credits for cookstove projects are compared, the Gold Standard method and the Clean Development Mechanism method. Different carbon credit scenarios are evaluated for how they compare to estimated health impacts when switching from a traditional biomass stove to each of the other ten alternative stove-fuel combinations including three basic improved biomass stoves, two gasifying biomass stoves, two coal stoves, one charcoal stove and two liquid fossil fuel stoves. Tradeoffs between the maximization of co-benefits were found to exist, with carbon credits inherently accounting for climate benefits, but not health.The three stove types achieving the highest levels of co-benefits were the two liquid fossil fuel fueled stoves included in the analyses, kerosene and liquid petroleum gas, and a more technologically advanced gasifying biomass stove with a battery powered fan. Yet they were also the most expensive and the fossil fuel stoves were treated very differently in the two methodologies, creating a diffusion barrier to achieve the highest maximization of co-benefits.The Gold Standard methodology consistently calculated more carbon credits than the Clean Development Mechanism, largely due to its inclusion of methane emissions in its calculations. Including black carbon emissions in theoretical carbon credit calculations also significantly increased the number of credits calculated. If accounted for in such equations this could greatly increase the amount of income earned per project as well as change how such projects are designed and approached due to the large increase in potential credits calculated. As health and other development benefits are not inherently included in carbon credit calculations, in order to achieve ‘win-win’ outcomes, deliberate decisions about project design need to be made to ensure such objectives are actually met and not simply assumed.
There has been a growing interest in land-use change and forestry activities for advancing the global goals of climate change mitigation and rural development. Because of its links to agriculture, the main livelihood activity of the rural poor in most developing countries, one particularly promising land-use is agroforestry, the use of land for both agricultural and silvicultural activities. The potential for agroforestry to deliver rural development and climate change mitigation benefits is well documented. There is considerable hope and expectation that agroforestry will be able realize co-benefits, where projects seek simultaneous goals of improving human welfare and mitigating climate change. However, it is less clear how and whether both goals might be accomplished in practice. Through an analytical literature review of rural development and carbon forestry literature, and a qualitative case study of participant experiences and understandings in smallholder tree planting initiatives in Uganda, this thesis explored the following overarching research questions:1. What are areas of likely tension and synergy when smallholder agroforestry projects in developing countries attempt to realize co-benefits for rural development and climate change mitigation?2. How should smallholder planting projects be designed to effectively maximize the delivery of benefits for both development and carbon goals?Both the case study and review of the literature suggest that projects seeking co-benefits from smallholder tree planting initiatives will encounter substantial tension between practices best suited to realizing development versus carbon benefits. These projects have considerable potential to fail in meeting expectations. Explicitly seeking ancillary benefits in projects that have primary goals of development or climate change mitigation may be a more effective way to more quickly expand the use of smallholder planting projects and attain both types of benefits, while concurrently providing opportunities to learn from experience and move towards the development of best practice for delivering returns for carbon and development on the ground. Alternative approaches to project design and pathways to deliver development benefits may be more appropriate in smallholder carbon projects to overcome expected tensions in projects attempting to deliver both development and climate benefits.
