Andean Civilization and the US Food System

This semester I am taking South American Archaeology as one of my four classes. Right now, we are discussing pre-Incan Andean civilizations, some of which inhabited the area of Peru that we will be visiting on our upcoming trip. While developments in pre-Incan cultures might not be directly related to climate change, the topic of climate comes up often in the study of pre-Incan cultures, as it plays an important role in societies that are so connected to the Earth and the environment. There was, of course, no anthropogenic climate change during the pre-Incan period, but climate affects civilizations nonetheless. In fact, the collapse of the Tiwanaku was caused in part by a changing climate.
The Tiwanaku, a civilization present during the Middle Horizon period of Peruvian history, from about AD 500-1000, was already seeing fragmentation in their society near the late 11th century, as evidenced by the defacing of ritualistic monoliths– representing a ritual “killing” of the monolith’s ritual and power. But, beginning in the late 11th century and continuing for a few hundred years, a drought hit the altiplano region of the Andes, the location of the Tiwanaku capital. At the time, the Tiwanaku had a centralized food economy, and the drought put stress on this, exacerbating fragmentations in an already disjointed culture. Local production systems came under the control of local corporate groups exercising local autonomy over their region, taking power away from the elites of the society (Janusek). Tiwanaku civilization was really an alliance of many different ethnic groups, which probably made it easier for it to break apart.

Obviously, a development such as the one seen with the Tiwanaku can inform our current situation with global warming. For instance, the US, similar to the Tiwanaku, has a centralized food economy that could be damaged by the effects of current climate change. Because all areas of the country depend on a centralized production center, the whole country will feel the effects of climate change, as a decrease in crop yield in one part of the country will affect the quantity and quality of food shipped to the whole of the country. We are not only facing at long-term drought, as the Tiwanaku did, but also rising oceans, more extreme weather, and hotter global temperatures. While we might have a better infrastructure than the Tiwanaku did, if we don’t do anything, at some point we will not be able to deal with the fallout from current climate change. Further, even if the US can deal some of these effects, the same cannot be said for less developed countries. These changes will not only have damaging effects on human populations, but might even modify economic and government systems. Already, and as Michael Pollan hints at in his book, The Omnivore’s Dilemma, we are seeing, in some areas of the US, movement towards supporting locally sourced food (Pollan). Could this represent regions of the US starting to exhibit more local autonomy, due to the stresses put on the world’s economic and political systems by climate change? Furthermore, private corporations and subnational governments are working together to form transnational governance networks, for the purpose of working to mitigate and adapt to climate change below the realm of international negotiations, as they realized some of the failures of the UNFCCC and Kyoto Protocol. I’m not saying our whole civilization is going to collapse due to climate change, but climate change will definitely affect more than just our daily everyday life. It will affect the whole of human civilization.

What Actually Is Nature?

In addition to our mosaic courses, Global Climate Change and Global Environmental Challenges and Governance, I am taking an elective course, History of the Environment. This course takes us way back to the original hominids and the beginning of human interactions with the environment.

Contrary to popular belief, humans have been altering the Earth’s natural landscapes from centuries before the industrial revolution. If you feel bad about your environmental footprint, your ancestors are to blame. Our ancestors have been exploiting Earth’s resources since their existence, and yes that includes Native Americans. Even when humans aren’t transforming the land, natural occurrences and other organisms do. One of the debated topics in class is questioning What is nature? Is there such thing as “pristine” wilderness? Well, I hate to break it to you but there is no such thing as pristine wilderness, there are no places that remain untouched. Some people identify nature as a getaway from urban centers to the country or forests. However these “natural” places were created by humans. Most of the species that exist now did not exist before our time. Do you have a dog? Well, dogs did not always exist until humans selectively domesticated wolves. And that is just one example. The primitive hunter and gatherer societies caused the megafaunal extinction, and we will never get to meet any of the large species once served on a dinner plate…or rock. Since the discovery of fire, one of human’s greatest accomplishments, Earth’s landscapes have been forever transformed. Slash-and-burn methods, or fire-stick farming, have been a major part of human interaction with the land. The aboriginals in present day Australia were complete pyromaniacs and actually burned the land so intensely that today’s existing landscapes are a product of it. Some primitive civilizations exploited their land so badly it resulted in their own self-destruction.

So, the history of the environment has made me aware that the transformation of Earth’s landscapes is not at all a new phenomenon. Will history repeat itself? Is our present day society on its way to self-destruction?

As I now know nature is not defined as “pristine wilderness” I am still looking for a new definition. How would you define nature?

As an Earth Sciences major at Dickinson College I am well aware of the seminars that we host as a department in order to foster an open platform to share student-faculty research, relevant geoscience news, geologic field excursions, and more. I have personally participated in two seminars in which I helped present student-faculty research in Iceland and a field excursion in Baffin Island, Canada.

Today, I attended a seminar of this sort but the Physics department hosted it. What attracted me most about this seminar was the topic of discussion in lieu of all of my studies so far within my courses, ERSC 204: Global Climate Change and ERSC 331: Chemistry of Earth Systems. Additionally, Professor of Meteorology at Pennsylvania State University, Kenneth J. Davis, presented his talk in a way that was readily accessible to the non-physicist.

This Physics Colloquium was officially called “The Breathing of the Earth and Fires of Industry: Measuring Greenhouse Gas Sources and Sinks at Regional Scales”. I found this talk compelling, because Davis spoke passionately about human activity increasing the greenhouse gas concentration in the earth’s atmosphere, resulting in an irreversible greenhouse effect. I especially appreciated his position on the matter because he was proving anthropogenic climate change with physics equations that I had never even heard of before! As a budding Earth scientist I found this talk to be extremely conducive to my climate change background as a whole, because I had never seen the information presented in that way and everyday I am realizing that this is truly an interdisciplinary field of study.

Davis spoke about the distinct methods for data collected like tower-based turbulent flux measurements, extrapolation of ecosystem fluxes across space using space-based remote sensing, and atmospheric budgets that utilize weather forecast systems combined with tower-, aircraft- and satellite-based greenhouse gas concentration measurements. Overall, I am happy to say that this talk has prompted me to look into reaching a stronger background in physics within my Earth Sciences major.

Discounting the Future

globe

Many of the possible effects that climate change poses have a temporal component to them: they will be realized and compounded over time.  Thus, the actions and inactions of today’s generation will have significant effects on those that come afterwards.  This compounding effect has a fair amount of consensus among environmental economists; however, there is not consensus on how much we should take those future effects into account during current decision-making processes for policies that might effect climate change.  This disagreement revolves around the discount rate, defined by the National Oceanic and Atmospheric Administration (NOAA) as the “rate at which society as a whole is willing to trade off present for future benefits.”  Because investment is inherently productive (that is to say, money is interest-bearing), resources on hand today are more valuable than resources available later; the difference in the values placed upon money today and in the future is where the disagreement lies.  

Take, for example, a future benefit of $1000 to be accrued in ten years: how much would I need to put in the bank now in order to have that $1000 at the end of the decade?  At a discount rate of 5%, it would be $613.90; at a discount rate of 8%, it would be lower, at $463.20.  Thus, the higher discount rate signals that society is more focused on present benefits than future benefits.

Let’s look at this in the context of climate change.  As a society, how much are we willing to spend now in order to protect the climate system from further “dangerous anthropogenic interference,” as is the UNFCCC’s stated objective, and to avoid future costs and damages?  At a lower discount rate, we place a higher value upon the maintenance of the climate system and pay a higher premium now in order to protect future generations.  At a higher discount rate, we place a higher value upon the current energy consumption patterns and are not willing to pay as high of a premium.

In Environmental Economics, my “wild-card” elective course for the Mosaic this semester, we discussed the argument that a near-zero discount rate is the most appropriate response to the effects of climate change.  We need to take aggressive action now and invest as much in climate mitigation and adaptation as possible in order to stay below the 2 degree Celsius threshold put forward by the UNFCCC.  If we do not do so, the costs borne upon future generations will be greater, as will the damages and level of disruption to our lifestyle that will occur from climatic change.  A discount that is higher than zero or near-zero could jeopardize the 2 degree threshold, undercut the international negotiations of the UNFCCC, and threaten the generations that will come after us.

Trash Talk in America

from U.S. EPA and http://www.wec.ufl.edu/extension/gc/harmony/waste.htm
from U.S. EPA and http://www.wec.ufl.edu/extension/gc/harmony/waste.htm

Tonight at Sociology Professor Barnum’s Soup and Bread discussion in Dickinson’s Treehouse: The Center for Sustainable Living, we covered a variety of issues, one of them being trash. In a consumer society where items are created to last no more than three years, trash has become a much bigger part of American society than most Americans realize. According to Forbes, the U.S. is responsible for producing ¼ of the world’s waste, meanwhile making up only 5% of the world’s population. That’s way too much trash, and too much trash too responsibly remove from society.

How did Americans become so unaware of their waste habits? After all, according to Edward Humes, author of Garbology, per capita waste levels have doubled in the U.S. since 1960. Think of the phrase “out of sight, out of mind”. Once an American puts the garbage out on the side of the curb each week, the trash is no longer their problem and they can move on to collecting waste for the next week. The rest of the world, however, is not so ignorant toward the U.S.’s trash problem. Just take the floating trash island in the Pacific- an “island” made of plastic debris deposited into the ocean which will never fully decompose.

[youtube_sc url=”https://www.youtube.com/watch?v=fKBWNVNzaPo”]

When there were no municipal waste programs (granted there were, however, major health problems), people were reminded constantly of their trash- by its smell and its appearance. With American’s desire for homes to look pristine and neat, trash could definitely get in the way of this. If American’s were forced to deal with their trash for more than seven days at a time, actions and attitudes might be different. Disposable toothbrushes, Brillo Pads, and excessive paper handouts would feel more threatening once they needed to be stored for more than a week, making them no longer out of sight and so hopefully no longer out of mine. With a more “in your face” approach to America’s trash, the disgusting and greedy extent of its waste products could possibly decrease.

The Trillion Tonne Communique

imgres

Where does change happen? This is a very common question at Dickinson. The general answer is that it starts with yourself, spreads through your community, and then through the globe. For the purposes of what I want to discuss, change can happen with businesses too. In terms of climate change many look to business and the market as a significant factor to where GHG concentrations are currently. This is a large of debate and an entire separate discussion. What I am going to focus on is how businesses can make change happen by being vocal activists.

The Prince of Whales Climate Leadership Group (CLG) provides a forum for businesses around the world to come together and make their collective voices heard about the urgency of climate change issues. The CLG communiques are the outlet for this voice. Six have been released thus far, with the seventh not far from release. At first they followed significant COP decisions, but recently have been focused on broader issues. For instance, the most recent was in support of a global carbon price.

The next communique is nearly ready and firms have already begun to sign it. This seventh communique, the Trillion Tonne Communique, is for those who support the idea of a trillion tonne cap on carbon emitted. This is the number that was put, as a limit, to the 2 degrees Celsius maximum. It was brought to the attention of the mosaic a few weeks ago and immediately we acted on it. A letter was drafted to the President of the College and the Chair of the Board asking them to support Dickinson signing on to the Communique. The next day we had a meeting with the President, who then told us to pursue it through the chain of committees that would have been traditionally followed. It is now under review and we hope to have an answer in time for COP20.

Now, you may be thinking, Dickinson College is not a business. It is not, but it is a registered non-profit and therefore able to sign on. Why do this? For one, it is a simple gesture- as no real pledge needs to be made. On another level this could ignite an entirely new conversation and network. Imagine businesses and institutions of higher education collaborating and using their very different voices to demand action on climate change at an international level.

We will see what happens as we approach a meeting of the Dickinson Board and as we near COP20 in December. Let me know your thoughts on this below!

 

Have your cake and eat it too with the “Mixed-track” Approach

 

The Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP) has two objectives taken on by two different workstreams. The goals of the ADP are to develop a new framework that will govern all parties under the UNFCCC by the COP 21 in 2015 and to close the ambition gap by ensuring the highest mitigation efforts by all parties. Keeping in mind the golden number, 2 degrees Celsius, is the limited amount of global temperature rise. The complexities of climate change involve multilevel governance. Finding the best approach towards climate governance is a heavily debated topic, given the difficulty of reaching a global agreement. Two opposing approaches are a top-down approach and a bottom-up approach. These approaches are used to link the economy and greenhouse gas emissions.  Top-down involves a, “contractual approach favoring binding targets and timetables” (Bodansky, 1). While bottom-up involves, “facilitative approach favoring voluntary actions defined unilaterally”(Bodansky, 1). David Bodansky argues that an effective international agreement relies on multiple variables: stringency, participation, and compliance. However, “weakness along any of these three dimensions will undermine an agreement’s effectiveness” (Bodansky, 2). Which is why he argues both models should be merged in order to cumulate an effective agreement.

The Kyoto Protocol was expected to lead a long-term top-down approach for mitigating climate change. Developed and developing countries could not come to a consensus in the negotiation process. Instead, countries have taken on their own climate obligations through a bottom-up approach. The failure of the top-down approach through the Kyoto protocol allowed for alternative approaches to take way, such as the Cancun Agreements.  At Cancun, “the Brazilian government declared it would halt all deforestation in Brazil by 2025” (King, 2011).  A bottom-up approach essentially implements policies at the lowest level of organization. Thus, proposing the idea that action can be taken at every level. There are numerous municipal initiatives and cities that are the centers of innovation for more sustainable practices. While a top-down approach focuses its attention on mitigation, a bottom-up approach concentrates on adaptation and the notion of vulnerability. Local approaches tend to have more short-term results, whereas top-down methods involve long-term impacts.

A hybrid, or “mixed track,” approach will be necessary in order to establish absolute commitments. Both approaches have different strengths and weaknesses, but together the weaknesses are compensated. For example, bottom-up attracts participation and implementation but does not effectively enact regulations. On the other hand, top-down results show the opposite. Mitigation and adaptation are both equally important in combating climate change and can both be reached through a mixed track approach of governance. We must not only rely on global agreement and regulation, but also on local implementations and participation. A legally binding treaty would ensure compliance but in addition we need local projects and governance in order to take fast action. The combination of both top-down and bottom-up approaches will be the most effective route in achieving the post-2020 goals of the Ad Hoc Working Group on the Durban Platform on Enhanced Action.

COP21 calls for Momentous Mixin’

By Elizabeth Plascencia

A match was lit at COP17 in Durban, South Africa. The supplementary body known as the Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP) was established that December. The inclusive nature of this platform is proposed to ignite change at COP21 in Paris. The mandate of the ADP calls to “…develop a protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties, which is to be completed no later than 2015 in order for it to be adopted at the twenty-first session of the Conference of the Parties (COP) and for it to come into effect and be implemented by 2020” (UNFCCC, 2014). “Bottom-up” and “top-down” are two predominant approaches to climate change policy within the two decades of the work under the Convention. This seemingly urgent call of action as per the ADP requires a symbiotic relationship between the two. A “mixed-track” approach is better suited to achieving the post-2020 goals of the Ad Hoc Working Group on the Durban Platform on Enhanced Action under the balanced dimensions of stringency, compliance, and participation for all Parties.

The international climate regime exhibits both approaches working well independently to a certain extent. Therefore it is proposed that a combination of the two will facilitate a more efficient and effective global combat on climate change by 2020. Within the article The Durban Platform: Issues and Options for a 2015 Agreement, Bodansky clarifies the range of confounding variables to international agreements, historic context relating to the Convention, and options to possible Durban outcomes. I initially gravitated towards the “bottom-up” approach as better suited on the basis of personal optimism regarding local grass-roots movements and voluntary national programs. Upon reading the article I soon realized that there are hard to ignore pros to the “top-down” method and that solely voluntary programs do little when brought in a global context. I found that the policy informs and enforces to a further extent in which “International law can serve a number of catalytic and facilitative functions. Gathering such as the annual meeting of the UNFCCC Conference of the Parties can focus attention, help raise public concern, and prod states to do more” (Bodansky, 2012). Legal agreements, legislation, and recommendations remain crucial in terms of maintaining stringency. However, it is important to be mindful of all Parties’ capacity in order to balance compliance and participation.

Working towards the cooperation of 195 countries with distinct agendas and interests may seem like a nearly impossible task but in order to achieve equitable, efficient, and effective international policy a new approach must be considered. A “mixed-track” combining both “top-down” and “bottom-up” approaches is better suited to achieving the post-2020 goals of the Ad Hoc Working Group on the Durban Platform on Enhanced Action under the balanced dimensions of stringency, compliance, and participation for all Parties.

The Best of Both Worlds for 2015

eiffel tower paris

After negotiations floundered at COP15 in Copenhagen to produce a broad-based and aggressive agreement to succeed the Kyoto Protocol, the Durban Platform was created to direct and motivate such an agreement for COP21 in Paris next year. It called for an “agreed outcome with legal force” that falls within the UNFCCC’s framework and principles. David Bodansky stated that, in order for an international agreement to succeed, it has to include three criteria (stringency, participation, and compliance), and outlined possible approaches that could stem from the work of the Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP), either a top-down or bottom-up approach. From the information and framings provided by Bodansky, neither option is adequate as a viable solution by itself; rather, a mixed-track approach, which hybridizes both aforementioned approaches, would maximize the criteria and would provide a solid foundation for an international agreement to take effect after 2020.

The top-down approach, which could be seen as a continuation and expansion of what was seen in the Kyoto Protocol, places the main focus of climate governance and negotiations upon the international regime of the UNFCCC and other such institutions. These negotiations would focus upon an overarching emissions reductions target and how to delegate it among the Parties, and would present a take-it-or-leave-it type of agreement; nations would have to agree to the agreement as a whole, and would be legally bound to it and the prescribed actions within it. This, however, scares many nations within the UNFCCC, especially those key to any effective agreement (e.g. the United States, China, India, etc.) and could either jeopardize participation because it’s too stringent or stringency because countries would only sign on to an agreement that was not as aggressive as it could have and/or should have been. While it has produced success in the Kyoto Protocol, there are also hindrances inherently built into the approach that limit its effectiveness.

On the other hand, the Cancun architecture was born in response to the top-down approach taken with the Kyoto Protocol and advocated a bottom-up approach that placed national governments as the vanguards against the effects of climate change. Rather than having the international regime dictate what each country must do, this alternative approach empowers each nation to decide their best way to individually take action in mitigation and adaptation, which builds national buy-in and ownership of the country’s efforts. However, this produces an incentive for a nation to understate their capacity to mitigate/adapt or produce conservative and non-aggressive targets, thus imperiling the ultimate purpose of the UNFCCC to stem warming to two degrees Celsius.

As explained above, both approaches have their strengths and weaknesses, but neither fully maximizes the three criteria that are key to a successful international agreement. Together, however, a viable middle ground could be reached that synthesizes the strengths of both approaches and that fulfills the stringency, participation, and compliance criteria. The bottom-up portion of a mixed-track approach allows countries to make commitments in areas that are both most effective and within its capacity to achieve, producing what Bodansky called a “variable geometry.” It provides enough freedom in action that each nation may find and take the course of action that works best for them, without imposing a one-size-fits-all solution that is unrealistic and incongruent with the political, economic, and developmental realities of a particular nation. Also, it satisfies the voluntary “pledge and renew” actions most nations are now interested in, as flexibility is the new mantra, so to say, of climate negotiations post-Kyoto; participation would be maximized with these types of actions rather than legally-binding commitments because most nations are not willing to take that step, as seen in the Kyoto Protocol. Within this flexible structure, the top-down portion provides enough incentive and enforcement/oversight to motivate aggressive and directed action, essential if the UNFCCC is going to keep warming below the two degree target. Through oversight and recommendations, the international regime can make sure that nations aren’t shirking their “common but differentiated responsibilities” while still motivating each nation to find the best solution that fits within that responsibility and capacity.

An aggressive and broad-based agreement is absolutely essential in order to meet the two degree target set by the UNFCCC at its conception in 1992. The best way to achieve this is not through a single mechanism or approach, or through a small group of nations; a wide array of options and avenues for action is necessary in order to gain the participation of a wide base of countries. Finding the colloquial sweet spot where an agreement is stringent enough to be effective at taking action and meeting the two degree target but not too stringent that there is insufficient participation. Therein lies the challenge for the UNFCCC and its individual member-states, but, with the best of both worlds, success is within our grasp.

Leisure or Consumption?

In tonight’s Clarke Forum lecture with Mark Price, Ph.D. entitled, Fighting the Runaway Inequality: The Minimum Wage Controversy, a little light bulb went off.

When discussing the increased productivity of American workers occurring alongside the fall in the minimum wage adjusted for inflation. Thus, people are producing more while simultaneously making less money in wages. This extra time they have, Dr. Price pointed out, low-wage workers could either increase consumption or increase leisure time. As can be assumed in an American culture defined by consumerism, most chose more consumption and thus their activities in their free time require them to make even higher wages. This raises a predicament putting low-wage workers into further and further debt.

Going off of this, I started to think about what would happen if we consumed less? Our industrialized European peers got the message, pairing up industrialization and leisure, but America took the consumption road, leading to even more overworked members of society wanting more and more. To see what I mean, check out the “Story of Stuff” below.

[youtube_sc url=”https://www.youtube.com/watch?v=9GorqroigqM”]

So what does this have to do with global climate change? Imagine if Americans started to spend their free hours enjoying low-cost leisure time instead of consuming and working extra hours to fuel their consumption. First of all, if society really changes its ways from consumption, the amount of “low-quality” products requiring endless amounts of greenhouse gas emissions. Secondly, most low-cost leisure activities involve the outdoors in some way, whether in the form of hiking, a free concert in the park, swimming, walking, running, playing pick-up games, having picnics, gardening, biking, and I could go on forever. As we talked with James Balog in the Treehouse the morning of his lecture, his and many others’ environmental ethic comes from their love for spending time outdoors. Thus not only could more leisure time lead to less greenhouse gas emissions, but it could boost people’s environmental ethics as well, making it more likely for them to take action against climate change and urge others to do the same.

The tricky part is figuring out how to change a key component of society in place for 200+ years. Any ideas? I know I will start by spending my free time doing things outside.
