Local responses to disasters in Peru and Puerto Rico: An approach from zero-order responders
by Fernando Briones, Consortium for Capacity Building, Institute of Arctic and Alpine Research

This talk will be available via webcast here.

Abstract: During disasters there is a window of time before official and/or external support arrives. During this period, citizens must act unsupported by first responders – devising self-coping strategies in order to survive.  In the days, weeks and months following a disaster, local populations are still facing recovery with creativity.  The actions and experiences of citizens pro-acting to pave fruitful futures is valuable experience on improvements for disaster risk reduction and management.  Here we introduce the notion of Zero Order Responders (ZORs); they are the first to the unfolding events of a disaster, because they live at ground zero. In order to support this concept we review two extreme hydrometeorological events illustrating how local populations cope with disasters during the period before external support arrives. The data was collected by direct observations during the 2017 El Niño Costero-related floods in Peru, and by the review of press following 2017 hurricanes Irma and Maria destruction in Puerto Rico. The ZORs  testimony about  how they survived and their perception of preexisting preventative programming is likely the truest compass on the clearest path to improvements and the rethinking of measures developed dominantly from the top down.

BrionesFernando Briones is a Research Associate at Consortium for Capacity Building (Institute of Arctic and Alpine Research) of the University of Colorado, Boulder. He holds a PhD in Social Anthropology from The School for Advanced Studies in Social Sciences (École des Hautes Etudes en Sciences Sociales), Paris, France.

He has been consultant and researcher in Mexico, collaborator and lecturer of international organizations in Latin America such as FAO, UNDP and ECLAC. He is a member of the Scientific Advisory Committee for National Coordination of Civil Protection of Mexico, and a member of the National System of Researchers of The National Council of Science and Technology of Mexico.

His work focuses on disaster risk reduction, the understanding of risk perception, social vulnerability, resilience and the applicability of public policies on climate change adaptation. His articles, books and scientific reports have been mainly developed with research in Mexico, Brazil, Argentina, Peru and Central America.

McMurdo Dry Valleys: Ecosystems waiting for water by Dr. Diane McKnight, Professor

ABSTRACT:  The McMurdo Dry Valleys region in Antarctica is comprised of alpine and terminal glaciers, large expanses of patterned ground, and permanently ice-covered lakes in the valley floors, which are linked by glacial meltwater streams that flow during the austral summer. These valleys were first explored by Robert Scott and his party in 1903. In 1968 the New Zealand Antarctic Program began a gauging network on the Onyx River, a 32 km river that is the longest river in Antarctica. As part of the McMurdo Dry Valleys Long-Term Ecological Research project, our research group has continued to monitor streamflow in the Onyx River and 15 other first-order streams in adjacent valleys. We studied the linkages between hydrology, biogeochemistry and microbial community ecology in stream ecosystems through a period of climatic extremes. In the 1990’s, a cooling period continued that was driven by atmospheric changes associated with the ozone hole. In the summer of 2001/002, this cooling period was interrupted by several warm and sunny summers that created "flood events" in the valleys and caused much greater ecological connectivity. Further, we found that flow regime strongly influences the composition of the diatom community in the algal mats that are abundant in many of the streams. Many of the diatom taxa are endemic to the region, with a few endemic taxa being most abundant in wetland systems that only become active during flood events. During floods, the microbial mats are scoured from the streambed and mat material is transported to the closed basin lakes. Thus, understanding the relationship between mat communities and hydrology is useful for interpretation of the record of the stream diatoms preserved in lake sediments and perched deltas to reconstruct the hydrologic record beyond the limited instrumental record of the Dry Valleys.

Exploring multi-source remote sensing approaches to evaluate ecosystem dynamics

Melanie Vanderhoof, Geoscience and Environmental Change Science Center, USGS

As diverse sources of satellite imagery become increasingly available, so do opportunities for multi-source remote sensing analysis. M. Vanderhoof plans to share an overview of several recent and diverse projects including analyses focused on post-fire regeneration, wetland connectivity, and riparian condition in which multiple imagery sources were either integrated or used in a hierarchical manner. She welcomes discussion of the challenges and opportunities of integrating diverse satellite data sources.

Please join us from 1-2 pm on Wednesday, October 17th in SEEC S225!
