Description
This dissertation investigates the long-term consequences of human land-use practices in general, and in early agricultural villages in specific. This pioneering case study investigates the "collapse" of the Early (Pre-Pottery) Neolithic lifeway, which was a major transformational event marked by significant changes in settlement patterns, material culture, and social markers. To move beyond traditional narratives of cultural collapse, I employ a Complex Adaptive Systems approach to this research, and combine agent-based computer simulations of Neolithic land-use with dynamic and spatially-explicit GIS-based environmental models to conduct experiments into long-term trajectories of different potential Neolithic socio-environmental systems. My analysis outlines how the Early Neolithic "collapse" was likely instigated by a non-linear sequence of events, and that it would have been impossible for Neolithic peoples to recognize the long-term outcome of their actions. The experiment-based simulation approach shows that, starting from the same initial conditions, complex combinations of feedback amplification, stochasticity, responses to internal and external stimuli, and the accumulation of incremental changes to the socio-natural landscape, can lead to widely divergent outcomes over time. Thus, rather than being an inevitable consequence of specific Neolithic land-use choices, the "catastrophic" transformation at the end of the Early Neolithic was an emergent property of the Early Neolithic socio-natural system itself, and thus likely not an easily predictable event. In this way, my work uses the technique of simulation modeling to connect CAS theory with the archaeological and geoarchaeological record to help better understand the causes and consequences of socio-ecological transformation at a regional scale. The research is broadly applicable to other archaeological cases of resilience and collapse, and is truly interdisciplinary in that it draws on fields such as geomorphology, computer science, and agronomy in addition to archaeology.

Description
Large-scale land acquisition (LaSLA), also called "land grabbing" refers to the buying or leasing of large tracts of land, especially in Sub-Saharan Africa (SSA) by foreign investors to produce food and biofuel to send back home. Since 2007, LaSLA has become an important development issue due to the opportunities and threats for SSA countries. LaSLA has the potential to create local jobs, transfer technology, build infrastructure, and modernize SSA's agriculture. Nonetheless, it can also aggravate food insecurity, perpetuate corruption, degrade ecosystems, cause conflicts, and displace local communities. What drives LaSLA, what are its impacts on local people, and under what circumstances can we consider it as just and ethical?
To examine what drives LaSLA, I used country level data from 2005 to 2013 on economic conditions, natural resources, business practices, and governance to estimate LaSLA models. I find that LaSLA increases with increasing government effectiveness, land prices, and the ease of doing business, and decreases with stronger regulatory regimes. To assess LaSLA's impacts on local people, I conducted a comparative case study in Tanzania. I compare changes in peoples' livelihood between treatment villages (those experiencing LaSLA) and control villages (those without LaSLA projects). The results show that under current practices, the risks of LaSLA outweigh the benefits to local livelihoods, yet there are potential benefits if LaSLA is implemented correctly.
To philosophically examine whether LaSLA can be considered just and ethical, I apply John Rawls' theory of justice. The analysis indicates that from both procedural and distributive justice perspective, LaSLA currently fails to satisfy Rawlsian principles of justice. From these analyses, I conclude that if implemented correctly, LaSLA can produce a win-win outcome for both investors and host countries. I suggest that strong governance, rigorous environmental and social impact assessment, and inclusion of local people at all levels of LaSLA decision making are critical for sustainable and equitable outcomes.

Description
This dissertation explores how practices and interactions of actors at different scales structure social networks and lead to the emergence of social complexity in middle range societies. To investigate this process, I apply a complex adaptive systems approach and a methodology that combines network science with analytical tools from economics to the three sub-periods of the Prehistoric Bronze Age (The Philia Phase, PreBA 1 and PreBA 2) on Cyprus, a transformational period marked by social and economic changes evident in the material record. Using proxy data representative of three kinds of social interactions or facets of social complexity, the control of labor, participation in trade networks, and access to resources, at three scales, the community, region and whole island, my analysis demonstrates the variability in and non-linear trajectory for the emergence of social complexity in middle range society. The results of this research indicate that complexity emerges at different scales, and times in different places, and only in some facets of complexity. Cycles of emergence are apparent within the sub-periods of the PreBA, but a linear trajectory of increasing social complexity is not evident through the period. Further, this research challenges the long-held notion that Cyprus' involvement in the international metal trade lead to the emergence of complexity. Instead, I argue based on the results presented here, that the emergence of complexity is heavily influenced by endogenous processes, particularly the social interactions that limited participation in an on-island exchange system that flourished on the island during the Philia Phase, disintegrated along the North Coast during the PreBA 1 and was rebuilt across the island by the end of the period. Thus, the variation seen in the emergence of social complexity on Cyprus during the PreBA occurred as the result of a bottom-up process in which the complex and unequal interactions and relationships between social actors structured and restructured social networks across scales differently over time and space. These results speak more broadly about the variability of middle range societies and the varying conditions under which social complexity can emerge and add to our understanding of this phenomenon.
