Anthropogenic land use has irrevocably transformed the natural systems on which humankind relies. Understanding where, why, and how social and economic processes drive globally-important land-use changes, from deforestation to urbanization, has advanced substantially. Illicit and clandestine activities--behavior that is intentionally secret because it breaks formal laws or violates informal norms--are poorly understood, however, despite the recognition of their significant role in land change. This dissertation fills this lacuna by studying illicit and clandestine activity and quantifying its influence on land-use patterns through examining informal urbanization in Mexico City and deforestation Central America. The first chapter introduces the topic, presenting a framework to examine illicit transactions in land systems. The second chapter uses data from interviews with actors involved with land development in Mexico City, demonstrating how economic and political payoffs explain the persistence of four types of informal urban expansion. The third chapter examines how electoral politics influence informal urban expansion and land titling in Mexico City using panel regression. Results show land title distribution increases just before elections, and more titles are extended to loyal voters of the dominant party in power. Urban expansion increases with electoral competition in local elections for borough chiefs and legislators. The fourth chapter tests and confirms the hypothesis that narcotrafficking has a causal effect on forest loss in Central America from 2001-2016 using two proxies of narcoactivity: drug seizures and events from media reports. The fifth chapter explores the spatial signature and pattern of informal urban development. It uses a typology of urban informality identified in chapter two to hypothesize and demonstrate distinct urban expansion patterns from satellite imagery. The sixth and final chapter summarizes the role of illicit and clandestine activity in shaping deforestation and urban expansion through illegal economies, electoral politics, and other informal transactions. Measures of illicit and clandestine activity should--and could--be incorporated into land change models to account for a wider range of relevant causes. This dissertation shines a new light on the previously hidden processes behind ever-easier to detect land-use patterns as earth observing satellites increase spatial and temporal resolution.

In Latin America food insecurity is still prevailing in those regions where extreme poverty and political instability are common. Tseltal communities are experiencing changes due to religious conversions and the incursion of external political institutions. These changes have diminished the importance of traditional reciprocal and redistributive institutions that historically have been essential for personal and community survival. This dissertation investigated the impact that variations on governance systems and presence of reciprocal and distributional exchanges have on the food security status of communities. Qualitative data collected in four communities through 117 free lists and 117 semi-structured interviews was used to elaborate six scales that correspond to the traditional and civic authority system and to inter-community and intra-community reciprocity and redistribution. I explore the relationship that the scores of four communities on those scales have on the food security status of their inhabitants based on their results on the National Health and Nutrition Survey 2012. Findings from this study suggest that in marginalized communities that many scientists would described as experiencing market failure, participation in inter-community reciprocal, intra-community reciprocal and intra-community redistribution are better predictors of food security than enrollment in food security programs. Additionally, communities that participated the most in these non-market mechanisms have stronger traditional institutions. In contrast, communities that participated more in inter-community redistribution scored higher on the civic authority scale, are enrolled in more food aid programs, but are less food secure.

Institutional factors are rarely examined in disaster risks in the Himalayan region, as much of the focus so far has been on improving the scientific understanding of the natural hazards and risks. This is particularly true for glacial lake outburst floods (GLOFs), which are natural hazards endemic to high mountain ranges such as the Andes, Alps, and Himalayas. While these have put mountain communities at risk for centuries, vulnerability is viewed to be increasing due to climate change. While the science behind the causes and characteristics of these hazards is now better understood, there is an absence of research understanding the social, cultural and institutional drivers behind creating effective strategies to mitigate risks from GLOFs. This is more so for the Himalayan region, where institutions have recently started to address this risk, but contention between local communities and external organizations can hinder mitigation efforts. To better understand how people’s perception towards disaster risk, a study conducted by Sherpa et al. (2019) examined the socio-economic and cultural perceptions surrounding GLOF hazards.

This research highlighted gaps in how scientific knowledge is disseminated to local communities, and the resulting distrust in government mitigation projects such as lake lowering and Early Warning Systems. A clear need developed to conduct an institutional analysis of the governance systems responsible for disaster risk management and their interaction with local communities. This study examines the institutional conditions under which mountain communities create effective adaptation strategies to address climate induced hazards. We use a mixed-methods approach, combining: a) quantitative analysis of household surveys collected in 2016-2017 and b) qualitative analysis that maps out the various factors of institutions that influence the success of community-based adaptation efforts. Additionally, GLOF case studies from Nepal are compared to those in Peru, where institutions have a longer history of managing GLOF risks. The research finds that there are several considerations including: lack of cross-scalar communication networks, lack of local knowledge and participation in policy processes, and ineffective interorganizational coordination of knowledge sharing and funding streams for local projects. This disconnect between external versus local and informal institutions becomes an inherent issue in projects where agenda setting by external organizations plays prevalent roles in project implementation.
