Ecological drought in the 21st century [Wed. June 29]

Drought is often defined in meteorological, agricultural, hydrological, and socioeconomic terms, but recent hot, dry conditions worldwide and associated impacts to ecosystems, call for expanded consideration and a clear definition of ecological drought. The need to define ecological drought and include it in drought planning and mitigation efforts is a pressing concern because hotter ‘global change-type droughts’, multi-decadal ‘mega-droughts’, and human alterations of climatological, hydrological, and ecological processes increase ecosystem vulnerabilities and threaten human communities that depend on healthy, functioning ecosystems for critical services. Our working group is attempting to establish this much needed definition of ecological drought offer a “call to action” to operationalize ecological drought in the 21st century.

Green infrastructure on the ground: The politics of aquifer replenishment in Los Angeles

Sayd Randle, Doctoral Candidate in Environmental Anthropology from Yale University, will be presenting the roundtable for May 20th, 2015. Come learn about green infrastructure contributions to groundwater, an increasingly important issue in our drought-stricken state.

Abstract: The City of Los Angeles imports roughly 90% of its potable water supply from beyond city borders, and relies on local groundwater for the remainder. Environmentalists have long advocated for increased groundwater augmentation through rainwater capture and infiltration around the city homes, streets, and parks the sit above the basins. Recent drought conditions and surface water adjudications have turned policymakers’ attention to these techniques for producing an increased, “more secure,” in-city water supply. This paper uses a political ecology framework to examine the politics of reconfiguring quotidian city spaces to restock groundwater stores, drawing on fieldwork among city bureaucrats, environmentalists, and homeowners undertaking retrofits.
