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
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
The governance of natural resources often gets implicitly or explicitly shaped by the knowledge systems that are invoked for making decisions. These knowledge systems reflect the underlying notions of how human-nature relationships are conceived and operationalized by different stakeholders in the governance system. Conflicts in the science-policy interface in environmental governance arise when specific conceptions of nature dominate over other ways of knowing, when stakeholders with representing different knowledge systems have disproportionate degrees of influence in policymaking spaces, or when certain stakeholders are deracinated from their resources and long-held knowledge traditions. This dissertation examines the epistemic conflicts that exist in the Indian forestry that have led to a situation of policy stalemate in the governance system and continue to perpetuate colonial systems of scientific forestry and marginalize local knowledge traditions. To do so, this dissertation analyzes three datasets to understand the extent and consequences of this conflict in the forestry sciences in Indian academia. First, scientific discourses on the Indian Forest Rights Act are examined to understand the normative and epistemic practices that lead to differences in perspectives and scientific positions on forest governance. Second, the forest policy literature is analyzed using bibliometrics techniques to identify the intellectual and social silos in forestry sciences in India. Third, interview data from Indian forest scientists is analyzed to understand the inequalities within the science-policy interface in Indian forestry and how these perpetuate colonial legacies of forestry science. This dissertation concludes with recommendations and future pathways for knowledge integration and policy deliberations to make more decolonial, inclusive, and sustainable policies in Indian forestry.

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
Infrastructure systems are facing non-stationary challenges that stem from climate change and the increasingly complex interactions between the social, ecological, and technological systems (SETSs). It is crucial for transportation infrastructures—which enable residents to access opportunities and foster prosperity, quality of life, and social connections—to be resilient under these non-stationary challenges. Vulnerability assessment (VA) examines the potential consequences a system is likely to experience due to exposure to perturbation or stressors and lack of the capacity to adapt. Post-fire debris flow and heat represent particularly challenging problems for infrastructure and users in the arid U.S. West. Post-fire debris flow, which is manifested with heat and drought, produces powerful runoff threatening physical transportation infrastructures. And heat waves have devastating health effects on transportation infrastructure users, including increased mortality rates. VA anticipates the potential consequences of these perturbations and enables infrastructure stakeholders to improve the system's resilience. The current transportation climate VA—which only considers a single direct climate stressor on the infrastructure—falls short of addressing the wildfire and heat challenges. This work proposes advanced transportation climate VA methods to address the complex and multiple climate stressors and the vulnerability of infrastructure users. Two specific regions were chosen to carry out the progressive transportation climate VA: 1) the California transportation networks’ vulnerability to post-fire debris flows, and 2) the transportation infrastructure user’s vulnerability to heat exposure in Phoenix.

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
The crafting of cultural goods and ethnic arts have been stable means for making a living within many Indigenous communities throughout the world. In order to understand how crafting can be an avenue towards sustainable entrepreneurship, an analysis of the relationships between Indigenous crafting, Indigenous community life, sustainable agency, Indigenous concepts of wellbeing, and sustainable entrepreneurship is needed. Through three-papers focused on an extensive literature review (aggregate to all three papers) and ethnographic field research (semi-structured interviews, verbal surveys, and ethnographic observation) this dissertation examines how the act of Indigenous crafting as carried out by individuals within families and by families within Indigenous communities, link with social relationships, making a living, gender roles, and cultural identity and how these aspects of community life intersect with sustainable forms of agency, Indigenous concepts of wellbeing, and small-scale social entrepreneurial activities in the context of Indigenous crafting in a bid to indigenize the concept of sustainable entrepreneurship. This dissertation proposes a series of conceptual frameworks that depict the discussed linkages between Indigenous crafting, Indigenous community life, sustainable forms of agency, sustainable livelihood, and Indigenous concepts of wellbeing, in the context of sustainable entrepreneurship along with the relevant literature associated with each element in the frameworks. This dissertation draws from a qualitative ethnographic study on Mazahua artisans and their communities in Mexico in an attempt to understand and expand sustainable entrepreneurship from Euro-Western perspectives to Indigenous perspectives in order to better apply SE concepts in the development of an Indigenous fashion goods venture called Vitu™. This Indigenous venture, through the Indigenized sustainable entrepreneurship concept of Adaptive-Transformative Agency, will more deeply address justice, equity, and inclusion for Indigenous peoples and their communities pursuing community development through entrepreneurial activities.

Description
Machine learning (ML) and deep learning (DL) has become an intrinsic part of multiple fields. The ability to solve complex problems makes machine learning a panacea. In the last few years, there has been an explosion of data generation, which has greatly improvised machine learning models. But this comes with a cost of high computation, which invariably increases power usage and cost of the hardware. In this thesis we explore applications of ML techniques, applied to two completely different fields - arts, media and theater and urban climate research using low-cost and low-powered edge devices. The multi-modal chatbot uses different machine learning techniques: natural language processing (NLP) and computer vision (CV) to understand inputs of the user and accordingly perform in the play and interact with the audience. This system is also equipped with other interactive hardware setups like movable LED systems, together they provide an experiential theatrical play tailored to each user. I will discuss how I used edge devices to achieve this AI system which has created a new genre in theatrical play. I will then discuss MaRTiny, which is an AI-based bio-meteorological system that calculates mean radiant temperature (MRT), which is an important parameter for urban climate research. It is also equipped with a vision system that performs different machine learning tasks like pedestrian and shade detection. The entire system costs around $200 which can potentially replace the existing setup worth $20,000. I will further discuss how I overcame the inaccuracies in MRT value caused by the system, using machine learning methods. These projects although belonging to two very different fields, are implemented using edge devices and use similar ML techniques. In this thesis I will detail out different techniques that are shared between these two projects and how they can be used in several other applications using edge devices.

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.
