Happy Earth Day. I'm John Ciorciari and I teach mostly about international politics and policy here at the Ford School. And environmental issues come up often in my work. I'm looking at a variety of post-conflict or fragile states and how international interventions can help or hurt in the process toward building a lasting peace. And very often, environmental management or mismanagement is a key factor in that process. A country I work a lot on is Cambodia and so I'll use that as an example of a few of the ways that I think the environment is so relevant to the study of international politics and peace-building. In that country, you have a government in power that has moved in a more authoritarian direction in recent years and has also gotten closer and closer to, to China. In spring it's national development. And the mode of development that Cambodia is chosen is one that has a lot of adverse environmental effects. In particular, large-scale investment and hydro power along the Mekong river. Cultivation of huge tracts of land for palm oil plantations and deforestation of large areas of the Northwest near the Thai border. And each of those three areas of economic activity have resulted in considerable environmental harms that have affected nearby communities and in the downstream parts of the Mekong, where people have relied on the flow of that river for generations, for their livelihoods, for fishing. And, and now find that the river's course is altered and that their livelihoods are destroyed and sometimes they have to move away to, to other places. In the palm oil context where some of that chemical runoff and, and just the taking of land itself displaces communities that have lived there for, for hundreds of years. And in the case of deforestation, you have the destruction of flora and fauna and in ways that again, have, have caused a real hardship for communities who lived in the upland areas of Cambodia for as long as anyone can remember, all of those problems have, have fed into broad, popular dissatisfaction with the government, which in turn has meant that they haven't been as willing to vote for the incumbent regime. And the incumbent regime seeing less need for, sorry, seeing less prospect, they would win at the polls as resorted more to, to bribery and violence to be able to maintain its position and power. And so a peace process that's existed in Cambodia for about a quarter of a century is under serious challenge in no small part because of environmental issues and the human consequences thereof. So I'm really excited about the initiative that you have here for Earth Day and to look at all of the intersections that the environment has across policy domains. I look forward to speaking with any of you who are interested about this topic. And again, wish you a happy Earth Day.
