Benno Hansen - Sieg heil, Homo sapiens: Eradicating lesser species with biodiversity loss and climate change
by Benno Hansen in Climate Change - TH!NK ABOUT IT - Benno Hansen
2009 was the year of COP15 and climate change. But 2010 is the United Nations International Year of Biodiversity. These two subjects are inextricably linked, however.
And when promoting the biodiversity cause change makers can just build on their nice experiences from COP15 in communicating an abstract subject that calls for societal changes going against current economic dogma, right?
This article looks at the problems and what can be done about them. We have the know-how and some opportunities - we just have to start using this knowledge... Read more »

Indigenous Peruvians and police in deadly clashes at oil and mining protests

Sometimes researchers are blamed of being alarmists stirring up fears of a fictional dystopia by the business-as-usual crowd. But it seems a forewarning of conflict over oil in Peru is proceeding according to exactly such a warning. The news first...... Read more »

Opinion: Nations don't go to war over water
by Benno Hansen in Ecowar
Writer Wendy Barnaby has written an essay for academic journal Nature in stead of a book for her publisher as the conclusion on "water wars" wouldn't sell. Some facts...There are 263 cross-boundary waterways in the world. Between 1948 and 1999, cooperation over water, including the signing of treaties, far outweighed conflict over water and violent conflict in particular. Of 1,831 instances of... Read more »

Ecowar: The political ecology of war
by Benno Hansen in Ecowar
So far this blogging project has been characterized by the Google News Alert I set up way back when I first got the idea and whatever inspiration I got studying for my bachelor's and master's degrees in horticulture, a natural science. But I just did a search using both regular Google (doh!) and Scholar using all fields of science not just the exact ones. There is a lot of texts out there... Read more »

Three cases of migration and conflict: Hurricane Katrina, Bangladesh and The Dust Bowl
by Benno Hansen in Ecowar
"Environmental change can trigger large out-migration, which can cause violent conflict in areas receiving migrants."
A peer reviewed article on environmental migration would fit right into my little project here, right? As I realized Reuveny's Ecomigration and Violent Conflict: Case Studies and Public Policy Implications was a look at only three incidents and that two of these were from the USA... Read more »

Environmental degradation kills 62 million people each year
by Benno Hansen in Ecowar
Do you think the headline figure sounds a little bit too high? Perhaps you are right because the year 2007 study I just read includes such causes of death as AIDS and second hand smoking. But rather than being just a look at the body count it's actually an assessment of the relationship between population growth and escalating degradation of the environment and how both factors kill people.

Natural resources and civil war
by Benno Hansen in Ecowar
My third research blogging post takes a real quick look at What Do We Know about Natural Resources and Civil War? by Michael Ross, year 2004. It is a review of several other studies; work by Paul Collier, Anke Hoeffler and James Fearon seems to have been among the most influential and the work of Le Billon - which I blogged about this March - is reviewed too.
The studies vary widely in scope and... Read more »

Climate change and conflict frequency
by Benno Hansen in Ecowar
The cornerstone of this blog here is a peer reviewed correlation of climate and war in historical China: see my first post from July 2007. I just wrote a thorough summary of the article at Shvoong.com; here's a shorter version and my own take on it.
Short summary
Zhang's study is a thorough mathematical correlation from climate to war frequency done on a macro-historical level. Warfare has... Read more »
