鈥淐hina is building roads right up to the border and we have to follow suit.鈥� There is an urgency in the road building activity on India鈥檚 borders. These roads, we are told, will secure the nation and bring development to its peripheral areas. In this paper, I go deeper into...

In what sense is the 21st century world "urban"? In this lecture, Neil Brenner critiques contemporary ideologies of the "urban age," which confront this question with reference to the purported fact that more than 50% of the world's population resides within cities. Against such demographic, city-centric understandings, Brenner excavates Henri...

Assessments of the sustainability of smallholder agriculture in Africa have focused on soil fertility decline. The forms in which these scientific assessments take are shaped by disciplinary traditions, development prerogatives, and assumptions about the social 鈥渄rivers鈥� of environmental change. The dominant approach in Africa today creates nutrient budgets for land...

The Colorado Rockies span an elevation range of more than 2000 m, extending from the foothills with limited winter snow up to high mountain slopes, where snow lasts most of the year. This talk will cover catchment to regional-scale research that addresses questions about where, when, and how tributary streams...

Stable isotopes of carbonate have long been used to reconstruct past climate and environmental conditions. The recent development of the clumped isotope paleothermometer has expanded the range of possible applications of these isotopic techniques to cover more environments and time periods. My research uses these isotopic tools to reconstruct past...

The physical and biological architecture of the Earth鈥檚 Critical Zone controls hydrologic partitioning, storage, and chemical evolution of precipitated water. The Critical Zone Observatory (CZO) network is a consortium of field sites that provides an ideal platform to research linkages between catchment structure and hydrologic function across a gradient of...

British Columbia: 2017 Wildfire Index* Total number of fires: 1217 Ignitions by lightning on July 7: 138 Days in a provincial state of emergency: 69 Number of temperature records 'shattered' this summer: 85 Percent of province in moderate to extreme fire danger on August 10 and 11: >99 Size in...

Throughout history, humans have always valued the view from above, seeking high ground to survey the land, find food, assess threats, and understand their immediate environment. The advent of aircraft early in the 20th century took this capability literally to new levels, as aerial photos of farm lands, hazards, military...

The availability of water and nutrients in soil and weathered rock influences the distribution of vegetation and its vulnerability to land use and climate change. We explored these relationships by combining geochemical and geophysical measurements at three mid-elevation sites in the Sierra Nevada, California, where a recent historic drought killed...

Over the twentieth century, it became more difficult for children born to poorer parents to climb the socioeconomic ladder. Declining upward mobility in the United States is now understood as a local problem, which could be addressed through place-based policy. Relatively little is known, however, of the malleability or historical...
