Artifacts, including ceramics, ground stone, and soil samples, as well as dental calculus, recovered from sites in the eastern North American central Plains were submitted to multiple laboratories for analysis of microbotanical remains. Direct accelerator mass spectrometer (AMS) dates of 361–197 cal BC provide evidence for the earliest use of maize (Zea mays ssp. mays) in this region. Squash (Cucurbita sp.), wild rice (cf. Zizania spp.), and palm (Arecaceae sp.) microremains were also found. This research adds to the growing evidence of the importance of microbotanical analysis in documenting plant use and in the identification of early maize. The combined data on early maize from the eastern Plains adds to our understanding of the timing and dispersal of this crop out of the American Southwest. Alternative explanations for the adoption and early use of maize by eastern central Plains communities include its value as a secondary resource, as an addition to an existing farming strategy, or as a component of Middle Woodland rituals.
This article examines the management and instrumentalisation of migration and mobility as an area of contested governance in civil wars. Building on work in migration studies and rebel governance, it shows how migration and mobility regimes form part of the structure of violent armed conflicts, as both states and non-state actors seek to control processes and consequences of mobility and migration to their advantage. Governance of migration during conflict involves the strategic use of mechanisms of migration governance for the purposes of achieving conflict aims. This article develops a framework for understanding how migration governance is instrumentalised in civil war as a means of managing and controlling populations. The framework is then applied to the case of the Kurdish conflict in Turkey and beyond through an analysis of three areas of migration governance that have played significant roles in this extended regional conflict: forced migration and refugee governance; border management; and diaspora engagement. The analysis provides a challenge to dominant state-centric, securitisation and humanitarian approaches to migration and security by pointing to the political and spatial complexity of contested migration governance in situations of protracted conflict.
Stratospheric Aerosol Injection (SAI), is often referred to as a ‘Plan B’ if mitigation strategies to reduce emissions fail and the need to rapidly reduce global temperatures becomes urgent. In theory, SAI would help buy more time to bring carbon and other emissions down while also cooling or keeping the planet below the threshold for dangerous warming, though it is not a solution to the problem of climate change in itself. What little attention it has received in International Relations (IR) is usually focused on the need for governance of the technology and assumes that development and use of the technology will be driven primarily by vulnerability to climate impacts. Through an analysis of common security assumptions and preemptive security framings the article shows that while current assessments of SAI focus on the technology’s environmental impact, broader political and security dynamics, particularly the desire to render climate change more intelligible as a security problem with a solution may have substantial influence on how the technology is used and by whom.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
