Is the threat of regulation enough to incentivize cooperation from nitrogen polluters?

Posted 01 Jun 2015 / 0

National Public Radio All Things Considered “It’s Raining Nitrogen In A Colorado Park. Farmers Can Help Make It Stop” What I find interesting about this example is how the local nature of this problem creates greater incentives for “voluntary” measures taken by polluters to reduce the impacts of their polluting activities. Because the effects of Read More

My ecological footprint for 2014-2015

Posted 06 Apr 2015 / 0

Every year in my ecology courses I have my students complete an ecological footprint analysis of their own lifestyle and the lifestyle of an older relative. I have been asking my students to do these for each of the eight years that I have taught at Pratt Institute, so I have accumulated a lot of Read More

Review of What We Made by Tom Finkelpearl

Posted 13 Aug 2014 / 0

I study cooperation. I can say this honestly only with some caveats. I am very interested in what allows cooperation to evolve in biological systems, as cooperation seems to defy the Darwinian imperative to serve the needs of self-replication and yet is unexpectedly prevalent in nature. In particular I am interested in human cooperation, which Read More

Water, Alfalfa, China, and a modern Tragedy of the Commons

Posted 12 Aug 2014 / 0

NPR Morning Edition “In Time Of Drought, Arizona’s Alfalfa Exports Are Criticized” There are so many interesting aspects to this story. First and foremost, it illustrates that “tragedies of the common” are entirely, well — common — in modern economies. The rules of resource use dictate whether that resource will be over-exploited: if there are Read More

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

CNN tackles climate change by explaining public goods games!

Posted 15 Jan 2014 / 0

I almost fell out of my seat when I found this video while searching for a concise source explaining why we don’t have an international climate change agreement. This short television piece is basically trying to explain the dynamics of climate change agreement as depicted by Milinski and colleagues (2008) in their PNAS paper “The collective-risk Read More

US EPA’s EnviroAtlas project promises to give researchers, students new insights into the geography of ecosystem services

Posted 13 Aug 2013 / 0

At the 2012 Annual Meeting of the Ecological Society of America, I first learned about a really interesting initiative of the U.S. Environmental Protection Agency. The project –now dubbed EnviroAtlas — is dedicated to creating a free, interactive online tool for exploring the geography of ecosystem services. I had the opportunity to check out a beta version Read More

“Earth Hour” seeks to re-focus our attention on all the earth provides

Posted 11 Feb 2013 / 0

World Wildlife Fund Earth Hour Will an hour of darkness give us the time to contemplate both the importance of ecosystem services and how our voracious energy consumption threatens those services? It is certainly worth a try.

Governor Cuomo makes the connection between natural disasters and climate change, calls for building in resilience

Posted 01 Nov 2012 / 2

In an election season when global climate change has been a subject that neither Obama nor Romney seem interested in discussing (see reports by The New Yorker and The Huffington Post), along comes Hurricane Sandy. With the arrival of the second “100 year storm event” to hit the State of New York in as many Read More
