Henry Lovejoy Assistant Professor, Department of History University of Colorado Boulder Abstract: While scholars have amassed large amounts of data related to the transatlantic slave trade, a more pressing question lingers: Where did those 12.7 million people come from within pre-colonial West Africa before boarding slave ships destined for the...

Sharon Bywater-Reyes Department of Earth and Atmospheric Science University of Northern Colorado Abstract: The strength of interactions between plants and river processes is dependent on plant traits such as stem density, plant frontal area, and stem bending properties. In many rivers, the composition of riparian vegetation communities has changed because...

April 26 is the last colloquium of the semester. It features three different graduating PhD students doing short presentations of their theses. Spaces of Diaspora Policy by Aaron Malone This paper examines the transnational / translocal landscapes of migrant organizing and state diaspora policies. Examining early diaspora engagement practices, Smith...

Earth鈥檚 鈥渃ritical zone鈥�, the zone of the planet from treetops to base of groundwater, is critical because it is a sensitive region, open to impacts from human activities, while providing water necessary for human consumption and food production. Quantifying water movement in the subsurface is critical to predicting how water-driven...

Colloquium is co-sponsored by the Center for Asian Studies 40 years ago, upon announcing the 鈥淩eform and Opening-up鈥� of China, the Communist Party called for 鈥渟ocial forces鈥� to 鈥渟ubsidize and fill gaps in state services鈥�. This, combined with the dramatic environmental and public health implications of China鈥檚 rapid economic development,...

A vast literature establishes the importance of social capital to neighborhoods. Jane Jacobs famously argued that this capital is maintained through "cross-use of space," and James Coleman formalized it as the "closure" of human interactions. Many of these interactions require human mobility, so neighborhoods with higher social capital should be...

This colloquium discusses the air quality impacts of western U.S. wildfires and introduce the Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption and Nitrogen (WE-CAN). The WE-CAN project deployed the NCAR/NSF C-130 research aircraft in summer 2018 (22 July 鈥� 31 August) to sample wildfire smoke during its first day...

Lake Poop贸 was once Bolivia鈥檚 second-largest lake. Located at roughly 3700m in the semi-arid central Altiplano, shallow and saline Lake Poop贸 has long been recognized for its ecological importance and in 2002 was added to the list of internationally important lakes and wetlands included under the Ramsar Convention. In late...

In view of modern anthropogenic impacts, forecasted changes in climate, and resulting shifts in the frequencies and magnitudes of surface processes such as wildfires, landslides and large floods, reliable models are needed to monitor and predict the short-term evolution of the Earth's surface. Models generally consider climate and tectonics to...

Land-cover change from forest to agriculture is widely recognized as a primary cause of accelerated soil erosion. Floodplains in agricultural watersheds represent fluvial archives for understanding anthropogenic erosion and downstream sedimentation. These agricultural legacy sediments may be used to construct watershed sediment budgets and can help reveal pathways of hydrologic...
