Adaptation to climate change is a core sustainability challenge across the Global South. Development and government organizations conceptualize and govern climate adaptation by creating national and sub-national action plans and implementing projects. This dissertation confronts the inherent tensions that arise when formal planned adaptation interventions encounter the complex, often messy realities of the implementation context. In doing so, this research examines how planned adaptation—with its incentives, provisioned resources, prescribed behaviors, and expectations of commitment from target beneficiaries —interacts with individuals and communities already balancing diverse risks while pursuing their livelihood aspirations. Two broad questions guide this dissertation: 1) how is adaptation envisioned by planners and practitioners? and, 2) how do project beneficiaries engage with, and experience planned adaptation interventions? The research employs an exploratory and inductive qualitative research design. Using Foucault’s lens of governmentality, this research utilises document analysis to examine how the first wave of Indian adaptation projects envision goals, conceptualize problems, delineate roles, and frame expectations of intended beneficiaries. Next, using a case study of an adaptation project implemented in Uttarakhand, India, the study examines the motivations and associated trade-offs behind the engagement and disengagement of the intended beneficiaries: smallholder farmers. Insights from gender-differentiated focus group discussions guide this analysis. Both inquiries are supplemented with findings from semi-structured interviews with Indian adaptation experts and project implementers. The analysis finds that: 1) project reports construct identities of the climate vulnerable beneficiary, implicitly assigning roles and transferring responsibilities for sustaining adaptation efforts beyond project timelines, 2) project participants are not default beneficiaries, but instead exercise agency in decision-making by either opting-in or opting-out of planned initiatives, and 3) the implicit and explicit costs of engaging in planned adaptation interventions are substantial, encompassing significant contributions of time, physical labor, and active participation during and post the project period. This dissertation challenges existing notions of whom planned adaptation serves, and to what end, offering new insights into its design and effectiveness. Furthermore, this research suggests that for planned adaptation to be sustainable, a concerted effort to align with evolving needs, aspirations and livelihood shifts of those on the frontlines of climate change is essential.

Given increasing frequency and intensity of extreme weather events and disparities in socio-economic conditions, managing flood risks has become ever more challenging. Building a community flood resilience becomes an essential strategy to reduce flood risks and achieve sustainable development. However, enhancing community flood resilience presents numerous obstacles and potential downsides. To address such a challenge, this dissertation investigates the interactions among natural, built environment, and actor systems using a case study of flooding in Jakarta, Indonesia, focusing on the Ciliwung river watershed. The study first develops a conceptual framework for community flood resilience by integrating concepts from disaster, flood, and community resilience research to represent how water, structural elements, and actors are connected and can contribute to hazards and vulnerabilities. Building on the framework, the study utilizes a mixed-methods approach, combining stakeholder interviews with network and heatmap analysis to identify the roles and interconnections of relevant actors in Jakarta’s flooding. Next, the study employs a hybrid of agent-based and system dynamics modeling to explore the complex interactions among the watershed’s physical and actor systems. The model evaluates how the level of collaboration among government agencies affects flood management interventions and community resilience under various scenarios concerning weather patterns and land-use change. The research provides an exploratory tool and a strategic guide for enhancing community flood resilience. The stakeholder analysis reveals the complexity of stakeholder relationships and challenges such as imbalance in resource allocation, authority overlap, and low engagement. These insights highlight the need for trust-building, community involvement, and strategic alignment in flood management efforts. Systems modeling to derive policy recommendations bridges the gap between theoretical frameworks and governance challenges, offering empirical evidence of the critical role of governmental collaboration in reducing exposure to floods. The systems modeling results suggest that under conditions of uncertainties, enhancing community flood resilience requires a coordinated approach among stakeholders.

Food waste is one of the most significant food system inefficiencies with environmental, financial, and social consequences. This waste, which occurs more at the consumer stage in high income countries, is often attributed to consumers’ behavior. While behavior is a contributing factor, the role of other contextual factors in influencing this behavior has not been systematically analyzed. Understanding contextual drivers of consumer food waste behavior is important, as behavior sits in a matrix of technology, infrastructures, institutions and social structure. Hence designing effective interventions will require a systems perceptive of the problem. In paper 1, I used Socio-ecological framing to understand how personal, interpersonal, socio-cultural, built, and institutional environments contribute to food waste at the consumer stage. In paper 2, I explored the perception of stakeholders in Phoenix on the effectiveness and feasibility of possible interventions that could be used to tackle consumer food waste. In paper 3, I examined the impact of knowledge and awareness of the environmental consequence of food waste in terms of embedded water and energy on the cognitive factors responsible for consumer food waste behavior. Across these three papers, I have identified three findings. First, the most influential factor responsible for consumer food waste is meal planning, as many decisions about food management depend on it. However, there are many contextual factors that discourage meal planning. Other factors identified include the wide gap between food producers and consumers, the low price of food, and marketing strategies used by retailers to encourage food purchases. Systems level interventions will be required to address these drivers that provide an enabling environment for behavioral change. Second stakeholders in the city overwhelmingly support and agree that education will be the most effective and feasible intervention to address consumer food waste, 3) there is need to carefully craft education materials to inform consumers about other resources, such as water and energy, embedded in food waste to stimulate a personal norm that motivates change in behavior. In this study, I emphasize the need to understand the root causes of consumer food waste and exploration of systems level interventions, in combination with education and information interventions that are being commonly used.

Producing, transforming, distributing, and consuming food requires a multitude of actors, from the microbes in the soil to the truck drivers, from the salesperson to the bacterial life that supports digestion. Yet, the global food system – far from being neutral – unequally provides and extracts resources around the globe to serve and protect the needs of some, while excluding and/or oppressing others and producing trauma in the process. Drawing on feminist scholarship and permaculture research – two fields that discuss the importance of care but only rarely work together – and using social science methods, I explore how to integrate care into food systems, and what are the outcomes of such an integration. I first bring together the voices of 35 everyday experts from Cuba, France, and the United States (Arizona) and perspectives from ethics of care, creation care, indigenous scholars, and permaculture specialists, and I use grounded theory to develop a definition of care in food systems context, and a conceptual map of care that identifies motives for caring, caring practices and their results. I then discuss how caring practices enhance food systems’ adaptive capacity and resilience. Next, I study the relationship between a subset of the identified caring practices – what is recognized as “Earth care” – and their effect on well-being in general, and Food Well-Being more specifically, using three case studies from Arizona based on: (1) interviews of school teachers, (2) interviews of sustainable farmers, (3) a survey with 96 gardeners. There, I also discuss how policies and cultural transformations can better support the integration of Earth care practices in food systems. Then, I examine how urban food autonomy movements are grassroots examples of integration of care in food systems, and how through their care practices – Earth care, “People care” and “Fair share” – they can serve as a catalyst for social change and contribute to the achievement of the United Nations Sustainable Development Goals. Lastly, I conclude with recommendations to strengthen a culture of care in food systems, as well as limitations to my research, and future research directions.

Women’s contributions to agriculture are an essential factor in achieving food security in developing countries. In rice production, women’s involvement is usually limited to their labor participation. Differences in gender roles within the household hinder women from accessing productive resources and services compared to their male counterparts, leading to a gender gap in rice productivity. With the steady growth of rice productivity experienced in eastern India, it is essential to reduce the gender gap by providing women equal access to resources. However, there is little information on how the gender gap can be addressed between married couples in a patriarchal family structure like India. This dissertation analyzes the potential impact on rice productivity and input use when the spouse (wife) in the household has given access to resources (e.g., rice variety and credit). The first chapter analyzes the impact of a married couple’s decision-making strategy in choosing rice varieties on rice productivity and input use using an endogenous switching regression. The second chapter estimates the effect of access to financial services on technical efficiency using a stochastic production frontier framework. The last chapter evaluates how joint decision-making strategy influences the inverse relationship between farm size and rice productivity following a yield approach and quantile regression. The findings show that joint decision-making strategy choice leads to a higher rice yield and fertilizer usage while lower labor requirements. Regarding spouse access to financial resources, results show a significant difference in technological and managerial gaps. However, that households with access have a lower predicted rice yield than households without access. The last chapter shows that joint decision-making in the family still left the inverse relationship unchanged in examining the inverse relationship. The dissertation provides two significant implications. First, results provide evidence of gender-differentiated preferences for rice variety within the household that can affect rice productivity and input use. Second, the spouse’s access to credit does not necessarily lead to an increase in rice productivity. Thus, determining the primary purpose of why households avail financial services would be essential in analyzing its impact on productivity to avoid misleading results.

The food-energy-water (FEW) nexus refers to the interactions, trade-offs, and relationships between the three resources and their related governance sectors. Given the significant interdependencies, decisions made in one sector can affect the other two; thus, integrated governance can reduce unintended consequences and lead towards increased resource security and sustainability. Despite the known benefits, many governance decisions continue to be made in “silos,” where stakeholders do not coordinate across sectoral boundaries. Scholars have begun to identify barriers to the implementation of integrated FEW nexus governance, yet there is still minimal understanding of the reasons why these barriers exist and no theoretical framework for evaluating or assessing FEW nexus governance. Integrating the theory of collaborative governance with the concept of the FEW nexus provides an opportunity to better understand the barriers to and structures of FEW nexus governance and to propose solutions for increased collaborative FEW nexus governance in practice. To investigate this governance system, I examined the collaborative governance of the FEW nexus in the context of extreme urban water challenges in two urban case cities: Phoenix, Arizona, USA and Cape Town, South Africa. First, I performed a media analysis of the 2018 Cape Town water crisis to understand the impact of the water crisis on the FEW nexus resource system and the collaborative governance employed to respond to that crisis. Second, I conducted a systematic case study of FEW nexus governance in Phoenix, Arizona to understand barriers to collaborative governance implementation in the system and to identify opportunities to overcome these barriers. Finally, I presented a framework of indicators to assess the collaborative governance of the local FEW nexus. This dissertation will advance the sustainability literature by moving the concept of FEW nexus governance from theory and conceptualization towards operationalization and measurement.

The science community has made efforts for over a half century to address sustainable development, which gave birth to sustainability science at the turn of the twenty-first century. Along with the development of sustainability science during the past two decades, a landscape sustainability science (LSS) perspective has been emerging. As interests in LSS continue to grow rapidly, scholars are wondering what LSS is about and how LSS fits into sustainability science, while practitioners are asking how LSS actually contributes to sustainability in the real world. To help address these questions, this dissertation research aims to explore the currently underused problem-driven, diagnostic approach to enhancing landscape sustainability through an empirical example of urbanization-associated farmland loss (UAFL). Based mainly on multimethod analysis of bibliographic information, the dissertation explores conceptual issues such as how sustainability science differs from conventional sustainable development research, and how the past, present, and future research needs of LSS evolve. It also includes two empirical studies diagnosing the issue of urban expansion and the related food security concern in the context of China, and proposes a different problem framing for farmland preservation such that stakeholders can be more effectively mobilized. The most important findings are: (1) Sustainability science is not “old wine in a new bottle,” and in particular, is featured by its complex human-environment systems perspective and value-laden transdisciplinary perspective. (2) LSS has become a vibrant emerging field since 2004-2006 with over three-decade’s intellectual accumulation deeply rooted in landscape ecology, yet LSS has to further embrace the two featured perspectives of sustainability science and to conduct more problem-driven, diagnostic studies of concrete landscape-relevant sustainability concerns. (3) Farmland preservationists’ existing problem framing of UAFL is inappropriate for its invalid causal attribution (i.e., urban expansion is responsible for farmland loss; farmland loss is responsible for decreasing grain production; and decreasing grain production instead of increasing grain demand is responsible for grain self-insufficiency); the real problem with UAFL is social injustice due to collective action dilemma in preserving farmland for regional and global food sufficiency. The present research provides broad implications for landscape scientists, the sustainability research community, and UAFL stakeholders.

The past decades have seen major changes with globalization, increased trade, digital technologies, and the increased threat of climate change consequences. These changes in trends have changed how the world communicates, travels, produces, manufactures, and develops. Yet despite having the most advanced technologies and the most connected world to date, other aspects of development and quality of life have not kept up the pace in adapting and changing based on these trends. Specifically in developing countries, while the outside environment may be changing, the systems, structures, and societal values in place have not fully adapted. These aspects of society are naturally slower to change which can be dangerous when dealing with the current issues the world faces, for example the proven increase in climate change consequences. The consequences of slow or no changes at all in systems, structures, and societal values fall disproportionately on women who are often now bearing more responsibility without the benefits due to outdated structures that were developed based on other environments and priorities. This gap between the formal structures and the rapidly changing environments and its effect on women can be seen through analyzing specific common trends in developing countries, such as the feminization of agriculture and climate change. Analyzing this gap from these specific trends can give insight into possible solutions to both speed up the closing of the gap and lessen the burdens for women in the meantime. The role of informal or community networks should be considered as a possible way to do this. The case of St. Lucia and its experience with both the feminization of agriculture and the threat of climate change will be analyzed to understand how informal or community networks could serve to help close the gap and lessen the burdens for women.
