Classification of deltas by environmental stress

Posted on March 22, 2016 in News • Tagged with Research, Papers

A new paper was published online today: A global empirical typology of anthropogenic drivers of environmental change in deltas. In this paper, we develop a methodology to classify coastal river deltas by major anthropogenic drivers of environmental change. This will be published as part of a special issue in Sustainability Science later this year, titled Sustainable Deltas: Livelihoods, Ecosystem Services, And Policy Implications.

Abstract: It is broadly recognized that river delta systems around the world are under threat from a range of anthropogenic activities. These activities occur at the local delta scale, at the regional river and watershed scale, and ...

Upcoming AGU Talk - Delta risk metrics

Posted on December 04, 2015 in News • Tagged with Conference

My talk at AGU is scheduled on Thursday, December 17, 4:00-4:15, and titled The Geophysical, Anthropogenic, and Social Dimensions of Delta Risk: Estimating Contemporary and Future Risks at the Global Scale (GC44C-01). I'll be speaking in the Sustainable Deltas: Multidisciplinary Analyses of Complex Systems III session. Looking forward to sharing our recent work and hearing what others have been working on. I'll make sure to post the presentation here after the talk.


New delta risk research in Science

Posted on August 06, 2015 in News • Tagged with Research, Papers

My collegues and I have a new research paper being published in the August 7, 2015 edition of Science, titled Profiling risk and sustainability in coastal deltas of the world. We have incorporated relative sea-level rise (RSLR, the combination of oceanic sea-level rise and land subsidence) into a risk framework that account for varying exposure to hazardous events, as well as the vast differences in socio-economic vulnerabilty across the world's deltas. We've developed proxies for these risk components based on global remote sensing and numerical modeling, and estimated how risk is changing due to RSLR in 48 deltas ...

Science paper companion piece

Posted on August 06, 2015 in News • Tagged with Research

I've written a piece on TheConversation.com, to provide a shorter summary of the research recently published in Science. This should provide more context about what and why we did this work than one usually finds in academic papers. Please let me know what you think!

Those interested in more details about the global delta risk research being published today can find information, data sets, and delta maps developed for the study at www.globaldeltarisk.net. Thanks to Tian Luan, Fabio Corsi, and Anthony Cak at the CUNY Environmental CrossRoads Initiative for their help getting this site off the ground!


Invited AGU Talk - Delta risk metrics

Posted on July 20, 2015 in News • Tagged with Conference

I'm pleased to note that I've been invited to present a talk at the AGU Fall Meeting session Sustainable Deltas: Multidisciplinary Analyses of Complex Systems. My talk will be about recent research on delta risk and vulnerability metrics: "The Geophysical, Anthropogenic, and Social Dimensions of Delta Risk: Estimating Contemporary and Future Risks at the Global Scale". More details about this research and a forthcoming publication will be posted here soon!


AGU 2015 Session - River Fluxes Under Environmental Change

Posted on June 15, 2015 in News • Tagged with Conference

This year at AGU I will be co-convening a session on river fluxes and their response to environmental change with co-convenors Sagy Cohen (U-Alabama), Albert Kettner (U-Colorado), and Christopher Hackney (U-Southampton). The full title is "Numerical Modeling and applications of river fluxes in large basins under changing environmental conditions" (Session ID 8280). Here's the description:

Large river basins, extending from headwater sources, through the river system, to lakes, estuaries and coastal seas, are key components of the global (bio)geochemical cycles that couple the atmosphere, continents and oceans. Aquatic fluxes of carbon, nutrients and sediment from river systems play ...

Data workflows with SCons

Posted on March 05, 2015 in News • Tagged with Research, Tools

tl;dr: Using SCons for data workflows has its quirks, but can be very effective. And with a little upfront work, easy parallelism.

Recently I set to work updating an analysis of Mekong and Ganges surface water inundation trends that I was working on last year. In the time since then, my colleagues at City College have developed a new version of the global inundation product, SWAMPS (Surface Water Microwave Product Series, R. Schroeder et al., publication in prep). This analysis workflow involves importing inundation, precipitation, wave model output, and hydrological model output data, reprojecting to a common map projection ...

Post-AGU - Thanks!

Posted on December 22, 2014 in News • Tagged with Conference

Thanks to all the people who submitted abstracts to our Deltas and Coastal Wetlands session, and in particular our invited speakers, David Mohrig, Irina Overeem, and Houjie Wang. I even learned from Fedor Baart and collegues at Deltares and Delft University of Technology that the three inmates who escaped from Alcatraz in 1962 may have indeed made it to shore [pdf].


AGU 2014 Deltas Session

Posted on November 28, 2014 in News • Tagged with Talk, Conference

With co-convenors Yoshiki Saito (Geological Survey of Japan/AIST), Wenhong Li (Duke University) and Ge Sun (USDA Forest Service), we are convening oral and poster sessions on "Impacts of Global Change on Deltas and Coastal Wetland Ecosystems: Scientific Advances in Support of Socioecological Resilience." The poster session is on Tuesday morning, Aug 16, in Moscone West. The oral session is Tuesday afternoon, 1:40-3:40, in Moscone West 3007. We had a good number of very interesting abstracts submitted to the session. The oral talks were chosen to span both a range of delta and wetland systems (Wax Lake, Mekong ...

Mekong surface inundation talk

Posted on October 20, 2014 in News • Tagged with Talk, Conference

I'll be presenting a talk showing recent results on our development of an empirical surface inundation model. Key to this work is a new remote sensing inundation product out of Kyle McDonald's group here at CCNY.


Deltas in Times of Climate Change

Posted on September 10, 2014 in News • Tagged with Talk, Conference

I'm co-organizing a workshop, Science-to-Action, at the Deltas in Times of Climate Change conference at the end of the month, in Rotterdam. Hoping for a good crowd of scientists, stakeholders, and practitioners.
