The global south has seen a rush in large-scale land acquisitions (LSLA), recently leading to an overarching need for advanced understanding of its effects on sustainability of the environment and human systems. LSLA has been considered an engine for stimulating economic growth and reducing rural poverty for many developing nations. With a total of 2.6 million ha assigned to economic land concessions (ELCs) in 2012, Cambodia is an exemplar country in terms of LSLA in Southeast Asia. In this study, we plan to test whether LSLA produces a truly significant direct and indirect land use change that exacerbates environment degradation of forests in Cambodia. We will explore about to what extent LSLA affected forested areas, facilitated forest loss, and caused forest carbon emission in Cambodia during 2000-2016. We will employ a new archetypical analysis framework, a propensity score method, and a set of remote sensing time series data at the communal scale to empirically estimate the temporal-spatial effects of LSLA for forest carbon emissions associated with forest loss inside and outside ELC boundaries. Based on a suite of empirical estimates, we will recommend and/or propose some desired national and international policies to control and/or minimize LSLA-induced environmental degradation in Cambodia and beyond.
