Description
Haiti has witnessed high deforestation rates in recent decades, caused largely by the fuel needs of a growing population. The resulting soil loss is estimated to have contributed towards a decline in agricultural productivity of 0.5% -1.2% per year since 1997. Recent studies show the potential of biochar use through pyrolysis technology to increase crop yields and improve soil health. However, the appropriateness of this technology in the context of Haiti remains unexplored. The three objectives of this research were to identify agricultural- and fuel-use-related needs and gaps in rural Haitian communities; determine the appropriateness of biochar pyrolyzer technology, used to convert agricultural biomass into a carbon-rich charcoal; and develop an action-oriented plan for use by development organizations, communities, and governmental institutions to increase the likelihood of adoption. Data were collected using participatory rural appraisal techniques involving 30 individual interviews and three focus-group discussions in the villages of Cinquantin and La Boule in the La Coupe region of central Haiti. Topics discussed include agricultural practices and assets, fuel use and needs, technology use and adoption, and social management practices. The Sustainable Livelihoods framework was used to examine the assets of households and the livelihood strategies being employed. Individual and focus group interviews were analyzed to identify specific needs and gaps. E.M. Rogers' Diffusion of Innovations theory was used to develop potential strategies for the introduction of pyrolysis technology. Preliminary results indicate biochar pyrolysis has potential to address agricultural and fuel needs in rural Haiti. Probable early adopters of biochar technology include households that have adopted new agricultural techniques in the past, and those with livestock. Education about biochar, and a variety of pyrolysis technology options from which villagers may select, are important factors in successful adoption of biochar use. A grain mill as an example in one of the study villages provides a model of ownership and use of pyrolysis technology that may increase its likelihood of successful adoption. Additionally, women represent a group that may be well suited to control a new local biochar enterprise, potentially benefiting the community.

Description
With increasing interest in sustainability and green building, organizations are implementing programs such as Leadership in Energy and Environmental Design for Existing Buildings: Operations and Maintenance (LEED-EB) in order to focus corporate sustainability goals on the operations of a facility and the practices of the building occupants. Green building programs help reduce the impact of a facility and bring about several environmental benefits including but not limited to energy conservation, water conservation and material conservation. In addition to various environmental benefits, green building programs can help companies become more efficient. The problem is that organizations are not always successful in their pursuits to achieve sustainability goals. It frequently take years to implement a program, and in many cases the goals for sustainability never come to fruition, when in the mean time resources are wasted, money is spent needlessly and opportunities are lost forever. This thesis addresses how the Six Sigma methodologies used by so many to implement change in their organizations could be applied to the LEED-EB program to help companies achieve sustainability results. A qualitative analysis of the Six Sigma methodologies was performed to determine if and how a LEED-EB program might utilize such methods. The two programs were found to be compatible and several areas for improvements to implementing a LEED-EB program were identified.

Description
During the months from June to November 2012, the city of Bangalore was faced with a serious solid waste management (SWM) crisis. In the wake of the upheaval, the state court declared source segregation to be mandatory. Yet, while the legislation was clear, the pathway towards a course of action for the transition was not clear and hence, Bangalore was stuck in a state of limbo. The objectives for this thesis spiraled organically from this crisis. The first objective was to examine the gaps in Bangalore's transition to a more sustainable SWM system. Six particular gaps were identified, which in essence, were opportunities to re-shape the system. The gaps identified included: conflicting political agendas, the exclusion of some key actors, and lack of adequate attention to cultural aspects, provision of appropriate incentives, protection of livelihoods and promotion of innovation. Opportunities were found in better incentivization of sustainable SWM goals, protecting livelihoods that depend on waste, enhancing innovation and endorsing local, context based SWM solutions. Building on this understanding of gaps, the second objective was to explore an innovative, local, bottom-up waste-management model called the Vellore Zero Waste Model, and assess its applicability to Bangalore. The adaptability of the model depended on several factors such as, willingness of actors to redefine their roles and change functions, ability of the municipality to assure quality and oversight, willingness of citizen to source segregate, and most importantly, the political will and collective action needed to ensure and sustain the transition. The role of communication as a vital component to facilitate productive stakeholder engagement and to promote role change was evident. Therefore, the third objective of the study was to explore how interpersonal competencies and communication strategies could be used as a tool to facilitate stakeholder engagement and encourage collective action. In addressing these objectives, India was compared with Austria because Austria is often cited as having some of the best SWM practices in the world and has high recycling rates to show for its reputation.

Description
Widespread human rights abuses have been documented in global fisheries, prompting governments, intergovernmental organizations, non-governmental organizations, and businesses to reconsider human rights as a key tenet of seafood sustainability. New and existing approaches are aiming to integrate human and labor rights into sustainability initiatives. These efforts encompass the development of new tools for conducting human rights due diligence and the modification of market-based approaches like third-party certifications, fishery improvement projects, and buyer sourcing commitments to include criteria for social responsibility. It is critical to evaluate these approaches to better understand their efficacy and areas in need of improvement. This dissertation explores how approaches for seafood sustainability are being adapted to protect and respect human rights of fishers and fishworkers. First, I examine the efficacy of a recognized human rights risk assessment tool: the Social Responsibility Assessment Tool for the Seafood Sector (SRA). Through a preliminary assessment of human rights risk in Guyana’s artisanal fishery, I determined that the SRA is an effective approach to identify visible and potential risk, though it must be supplemented with engagement with fishers and fishworkers through interviews. Next, I evaluated labor conditions in the shrimp and groundfish fishery of the Guianas-Brazil Shelf using a novel evaluative framework for decent work. I uncovered cross-jurisdictional challenges including trafficking and limited worker representation. My evaluative framework enabled a holistic analysis of decent work, identifying linked concerns such as widespread illegal fishing and threats to food security. Finally, I conducted an analysis of market-based approaches that include criteria for social responsibility. Interviews with experts highlight that market-based approaches, particularly fishery improvement projects, hold great potential as strategies to improve human rights in fisheries. However, concerns around market-based approaches include a lack of strong enforcement mechanisms, limited worker representation, and the voluntary nature of initiatives hinder effective change on the ground. Overall, my research suggests that efforts to improve human rights in fisheries are nascent and need further development. By encouraging mandatory due diligence, improved worker representation, and stricter accountability, interventions can more effectively address risks and ensure rights of fishers and fishworkers are protected and respected.

Description
Development is a compelling, but imprecise goal. Although the concept can motivate action and mobilize resources, fundamental questions about what it means to ‘develop’ and what actions are required to achieve that goal remain the subject of intense debate. Faced with this uncertainty, development actors can look to two sources of guidance: other disciplines, or the practice of development itself. This dissertation explores the origins of the theories which guide development action and argues that in order for development to deliver on its mandate it must reject supposedly universal theories borrowed from other disciplines (‘exogenous’ theories) and instead must develop contingent, local theories based in the on-the-ground experiences of those doing development (‘endogenous’ theories).
This argument is demonstrated using the case of innovation theory in Guyana. Innovation and development are both popular ways to make sense of change and in recent decades they have become conflated, with innovation being presented as a near-universal fix for development problems. This discourse has taken root in Guyana, where the recent discovery of oil has made the questions of development increasingly urgent and the promise of innovation increasingly attractive. The argument proceeds in four phases:
Chapter one explores how and why certain theories become influential in development, then discusses the implications of doing development work based on ‘exogenous’ versus ‘endogenous’ theory. It then proposes four guidelines for the use of theory in development.
Chapter two traces how innovation came to become understood as a solution to development problems, and assesses whether and under what conditions it can be expected to contribute to development.
Chapter three turns to Guyana, and builds on interviews and participant observation to present an endogenous theory of innovation in Guyana. The chapter also explores the practical and methodological challenges of building such a theory.
Chapter four compares the endogenous theory of innovation presented in the previous chapter to several dominant exogenous theories, exploring the policy implications of each and demonstrating why the endogenous theory provides a superior source of guidance for development action in Guyana.

Description
Although Saudi Arabia is moving towards a sustainable future, Existing residential buildings in the country are extremely unsustainable. Therefore, there is a necessity for greening the existing residential building. Mostadam green rating systems was developed by the Saudi ministry of housing in 2019 to address the long-term sustainability vision in residential buildings in the country. By setting Mostadam requirements as an objective of the retrofit process, it will ensure that the building achieve sustainability. However, Mostadam is new and there is a lack of knowledge of implementing its requirements on existing buildings. The aim of this research is to develop a framework to green existing residential buildings in Saudi Arabia to achieve Mostadam energy and water minimum requirements. The framework was developed based on an extensive keyword-based search and an analysis of 92 relevant research. The process starts with assessing the building against the minimum requirements of energy and water of Mostadam. After that, optimization phase is conducted. Building information modelling is used in the optimization phase. Energy and water efficiency optimization measures are identified from the analysed literature. Revit is used in the base model authoring and Green building studio cloud is used to simulate the energy and water efficiency measures. Then, payback period is calculated for all the efficiency measured to assess the decision making. A case study of a villa in Riyadh, Saudi Arabia is provided. result shows that the implemented efficiency measures led to an increment of 37.5% in annual energy savings and 26.1% in the annual water savings. Results shows that the application of the proposed framework supports evaluating energy and water efficiency measures to implement it on the buildings to achieve Mostadam minimum energy and water requirements. Recommendations were made for future work to bridge the knowledge gap.

Description
This research will utilize the energy and poverty alleviation framework to investigate a sustainable energy ecosystem for the Wakapoa indigenous community of Guyana. Five questions guide the research – 1) Is there an energy access-development nexus? 2) Can the relationships and trends between key development indicators and electricity access guide policymakers on development activities? 3) Can small-scale concentrated solar and biomass systems provide adequate electrical power to meet the Wakapoa community's domestic and commercial loads economically? 4) What added social value could be generated from the energy system as per Wakapoa context? and 5) What governance systems can be considered to facilitate a sustainable energy ecosystem? In addressing questions 1 and 2, the research collected secondary data on selected countries' key development indexes from the World Bank and Our World in Data. Datasets include the human development index, human capital index, gross domestic product per capita, gross national income per capita, and electricity access. In addressing questions 3 to 5, the research utilized the convergent research design methods, where an inclusive data collection process targeted fifty (50) community residents as survey participants. Statistical analysis of the survey data proved useful in identifying the community needs for the renewable energy system design options utilizing system advisor model (SAM) software, identifying key economic activities that can add social value to the community, and giving key insight into governance practices preferred by the community. Key findings reveal that electricity access exerts a strong and moderate influence on key development indicators, the concentrated solar power and biomass hybrid system can satisfy the electricity demand of the community at the Tier-5 level that can support many traditional and non-traditional economic activities, while key governance support functions such as the community financial aid fund and community management committee can enhance the sustainability of the various operations as well as residents' well-being and livelihood. Future research can address project financing, community productive capacity, and the marketing of goods and services to promote a sustainable energy ecosystem.

Description
The United States building sector was the most significant carbon emission contributor (over 40%). The United States government is trying to decrease carbon emissions by enacting policies, but emissions increased by approximately 7 percent in the U.S. between 1990 and 2013. To reduce emissions, investigating the factors affecting carbon emissions should be a priority. Therefore, in this dissertation, this research examine the relationship between carbon emissions and the factors affecting them from macro and micro perspectives. From a macroscopic perspective, the relationship between carbon dioxide, energy resource consumption, energy prices, GDP (gross domestic product), waste generation, and recycling waste generation in the building and waste sectors has been verified. From a microscopic perspective, the impact of non-permanent electric appliances and stationary and non-stationary occupancy has been investigated. To verify the relationships, various kinds of statistical and data mining techniques were applied, such as the Granger causality test, linear and logarithmic correlation, and regression method. The results show that natural gas and electricity prices are higher than others, as coal impacts their consumption, and electricity and coal consumption were found to cause significant carbon emissions. Also, waste generation and recycling significantly increase and decrease emissions from the waste sector, respectively. Moreover, non-permanent appliances such as desktop computers and monitors consume a lot of electricity, and significant energy saving potential has been shown. Lastly, a linear relationship exists between buildings’ electricity use and total occupancy, but no significant relationship exists between occupancy and thermal loads, such as cooling and heating loads. These findings will potentially provide policymakers with a better understanding of and insights into carbon emission manipulation in the building sector.

Description
For decades, load shifting control, one of the most effective peak demand management methods, has attracted attention from both researchers and engineers. Various load shifting controls have been developed and introduced in mainly commercial buildings. Utility companies typically penalize consumers with “demand rates”. This along with increased population and increased customer energy demand will only increase the need for load shifting. There have been many white papers, thesis papers and case studies written on the different types of Thermal Energy Storage and their uses. Previous papers have been written by Engineers, Manufacturers and Researchers. This thesis paper is unique because it will be presented from the application and applied perspective of the Facilities Manager. There is a need in the field of Facilities Management for relevant applications. This paper will present and discuss the methodology, process applications and challenges of load shifting using (TES) Thermal Energy Storage, mainly ice storage.

Description
Without scientific expertise, society may make catastrophically poor choices when faced with problems such as climate change. However, scientists who engage society with normative questions face tension between advocacy and the social norms of science that call for objectivity and neutrality. Policy established in 2011 by the Intergovernmental Panel on Climate Change (IPCC) required their communication to be objective and neutral and this research comprised a qualitative analysis of IPCC reports to consider how much of their communication is strictly factual (Objective), and value-free (Neutral), and to consider how their communication had changed from 1990 to 2013. Further research comprised a qualitative analysis of structured interviews with scientists and non-scientists who were professionally engaged in climate science communication, to consider practitioner views on advocacy. The literature and the structured interviews revealed a conflicting range of definitions for advocacy versus objectivity and neutrality. The practitioners that were interviewed struggled to separate objective and neutral science from attempts to persuade, and the IPCC reports contained a substantial amount of communication that was not strictly factual and value-free. This research found that science communication often blurred the distinction between facts and values, imbuing the subjective with the authority and credibility of science, and thereby damaging the foundation for scientific credibility. This research proposes a strict definition for factual and value-free as a means to separate science from advocacy, to better protect the credibility of science, and better prepare scientists to negotiate contentious science-based policy issues. The normative dimension of sustainability will likely entangle scientists in advocacy or the appearance of it, and this research may be generalizable to sustainability.
