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
The proliferation of plastic has created a wicked global sustainability challenge. From the extraction of fossil fuels to end-of-life management and pollution, plastic imposes significant negative impacts to human health, economic well-being, and the environment. One proposed solution is to replace conventional plastic with biomass-based plastics and plastic alternatives (BBPAs), such as paper or bio-based plastics. While these products may have advantageous properties, they require biomass as a feedstock. Given the scale of the plastics problem, this biomass demand may be significant. In my dissertation, I evaluate the magnitude of biomass required, and assess the potential impact of this biomass demand on global land use. After examining the scope and the scale of the problem in chapter one, I evaluate the assumptions that have been made regarding the land-use impacts of BBPAs in chapter two. In chapter three, I use a global land-system model (CLUMondo) to evaluate the potential land-use change of large-scale production of BBPAs. In chapter four, I evaluate how certification schemes could be used as a policy tool to mitigate the land-use impacts of bio-based alternatives. I find that the current studies evaluating the land-use impacts of these products make optimistic and unrealistic assumptions regarding land-use. Using a global model, I show how high production scenarios of BBPAs could induce significant land-use change at the global level. Finally, I demonstrate that reliance on certification schemes would likely be insufficient to prevent negative impacts from this scale of land change. Overall, this dissertation suggests that large-scale replacement of plastic with BBPAs could incur significant land-use impacts. Policies designed to mitigate the impacts of plastic need to account for this impact to land-use, lest they risk substituting one global problem for another.
