The Shennong River is one of the tributaries to the Yangtze River in China. It is a sleepy river valley with farm houses nestled along the valley floor and its surrounding mountains. Farmers in this community must terrace the surrounding hills to have sufficient acreage to cultivate. This means laborious work by hand, bringing buckets of water up and down the mountains every day to make sure their precious crops are sustained.

This image submitted by Vicki Drake offers a picturesque visualization for some of the rural landscapes of the Chinese interior.  The Shennong River, or Shen Nong Stream, is one of the tributaries to the Yangtze River just miles upriver from the Three Gorges Dam.  The Shennong valley blends from agricultural landscape to geological landscape as its stream grade cuts one of the lesser gorges leading to the Yangtze in this high relief area.  The image can suggest the “sleepy” quality of the area, but can also foster recognition of the potential for natural disasters and difficulty in providing emergency services in such relatively remote, but populated area, as mentioned in the post Chinese Environmental Problems and the Potential for Change.

Concept Caching: Haiti and Dominican Republic political boundary

Fly along the political boundary between Haiti and the Dominican Republic, and you see long stretches of the border marked by a stark contrast in vegetation: denudation prevails to the west in Haiti while the forest survives on the Dominican (eastern) side. Overpopulation, lack of governmental control, and mismanagement on the Haitian side combine to create one of the region's starkest spatial contrasts. (c) H.J. de Blij

This image submitted by Harm de Blij reveals a striking landscape of deforestation and hints at the differing impacts of local politics and governance that is behind such a difficult global problem.  The image provides a pertinent partner for the discussion of deforestation in the post, Hopes for World Forests.

Hopes for World Forests

Deforestation has long been a troubling global trend that has affected most of Earth’s arboreal environments.  Discussions of this topic may often focus on the economic and agricultural reasons for the destruction of forestlands.  Juxtaposed are the greedy corporations and illegal loggers against indigent subsistence farmers desperate for land.  Either way, the discussion ends as so many talks of 21st century environmental problems often do: disheartened and despondent.  However, there has been much recent buzz in the media related to deforestation, and some of it actually hopeful.

A Newsweek article believes that Haiti’s economic recovery may be contingent upon the recovery of its forest lands.  Haiti’s trees have long been mowed down by colonizers, plantations, industry and locals alike.  It is hoped that reforestation will ultimately help to minimize the impact of natural disasters, like hurricanes and floods, and to restore nutrients to overworked agricultural lands.

On a global scale, recent policies of developing countries have made a concerted effort to remove illegally logged wood from world markets.  The New York Times Green blog reports on the European Parliament’s bill cracking down on timber from illegal logging.  Other countries from the developing world like Nigeria and Ghana to the developed world like the United States have previously contributed to fining or banning wood logged illicitly.

In particular, it is the Amazon that many environmentalists lay their hopes on.  The New York Times Dot Earth blog reports on the optimism that comes with Brazil’s current demographic and economic development trajectories and with restoration and preservation efforts of environmentalists on the ground.  The Amazon has also been the subject of a year-long study conducted by Brazil’s National Institute for Space Research (also reported with accompanying images at Surrey Satellite Technology LTD’s Space Blog).  They analyzed satellite images of the region which revealed a slowing of deforestation rates as compared with previous years.

The link between the world’s forests and possible climate change should also be discussed in any deforestation dialogue.  Earth scientists have long been studying the carbon cycle and tracking the ways that carbon is found in active and inactive stores throughout the biosphere, atmosphere, hydrosphere, and lithosphere.  One of the global scale puzzle pieces to this study has now been provided by NASA satellites as they mapped world tree heightsCNN argues that this will aid in tracking world forest carbon and study the ability of world forests to continue to take up atmospheric carbon. This map will also help to produce models to understand forest fires, ecosystems, and more.

A succinct article provided by the New York Times Green blog titled, “Is the tide turning on deforestation?” is suitable for most undergrad students and sums up these hopeful developments well.  Combine that with a recent BBC News article that reports the findings of the London-based think tank Chatham House observing a marked decline in illegal logging and discusses the major contributions to that trend.

However hopeful, this deforestation discussion should also end with a sobering dose of reality:  reiterating that deforestation, especially at the hand of illegal logging, is still a harrowing global problem.

Discussion Questions:

1. How might economic recovery connect to reforestation in the example of Haiti?  Explain the benefits of reforestation and how they will contribute to economic gains.

2. Suggest comparisons or contrasts of the policies against illegal logging between the developing world and developed world.  Think about production/consumption and source/destination streams, as well as underlying motivations at various scales.

3. How will the mapping of world tree heights help scientists to track carbon and understand climate change?

4. What hopeful trend countering deforestation do you think will make the most difference and why?  Do you have any other suggestions for what the global community can do to help save the world’s forests?

Disastrous Playlist (Redux)

Pursuant to my posting from last week concerning My Disastrous Playlist, I am posting the whole list of songs that I have put together for use during the breaks in my Natural Hazards class. I have added a couple of the suggestions provided by commentators, too – thanks!

James, I’m saving your suggestions for my Environmental Science playlist – stay tuned for that, or maybe you can post yours…? But I also like the idea of using songs to introduce specific lecture topics. How about this one for your insolation lecture: Why Does the Sun Shine? (The Sun is a Mass of Incandescent Gas) by They Might Be Giants, which I discovered while researching one of the other suggestions. I haven’t actually listened to it yet, but the lyrics start out:

The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where hydrogen is built into helium
At a temperature of millions of degrees

Yo ho, it’s hot, the sun is not
A place where we could live
But here on earth there’d be no life
Without the light it gives

Again my disclaimer for using the playlist – you need to actually LISTEN to all of these before you play any of them in your classroom. I have vetted them fairly thoroughly for overtly objectionable language, but everyone has different levels of tolerance. The range of musical styles represented here is very broad – everything from punk to alternative, hip-hop, reggae, inspirational, jazz, and traditional music. You have to decide what to play based on your own level of comfort and your students’ sensibilities.

But they’re all fun! So here’s my complete Disastrous Playlist – so far – along with the name of the album in parentheses; it’s in some kind of semi-alphabetical order, as per iTunes. By the way, so far Bob Dylan and Sufjan Stevens are tied for the most songs on the list:

Concept Caching: Soybean Agriculture in Presho, South Dakota

From our Concept Caching image cache that hopes to promote student spatial awareness by relating specific features on the Earth’s surface with their visual character and GPS coordinates. Through the site photographs and GPS coordinates demonstrate core concepts in geography.  Images are “cached” for viewing by core concept and by region.  Images are certainly useful for introducing visual content to students in all  Geography classes.

Soybeans growing in the semiarid ranchlands of western South Dakota.

This image submitted by Erin Fouberg provides a visualization of the scale and landscapes of crop agriculture in the United States.  The companion image description offers insight into this landscape and details over the two types of crop agriculture in this region.  It is also an interesting visual companion to some of the issues raised in the post, “Geographies of Green Diets.”

“Driving across the semiarid ranchlands of western South Dakota, I noticed the presence of a crop in the landscape that was recently found only in the eastern, moister region of the state: soybeans.

I called a colleague who works in agriculture at South Dakota State University to ask, “When did the cattle ranchers of western South Dakota start growing soybeans?” He replied, “When the soy biodiesel plants started popping up in Nebraska and Kansas and when genetically modified soybeans made it possible to grow the crop here.” He explained the development of Roundup Ready soybeans, a particular genetically modified soybean that can grow in more arid regions of the country. First, you plant the soybean; then you use an airplane to spray Roundup, a common weed killer that is manufactured by the company that produces the Roundup Ready soybeans, over the field. The application of Roundup over the entire field saves a lot of time and energy for the farmers because the genetically modified soybeans are resistant to the Roundup, but the weeds are killed. Monsanto, the company that produces Roundup, has developed soybeans, corn, cotton, and other crops that are resistant to Roundup.

Counter to the genetically modified Roundup Ready crops, organic agriculture —the production of crops without the use of synthetic or industrially produced pesticides and fertilizers—is also on the rise in North America. In wealthier parts of the world, the demand for organic products has risen exponentially in recent years. Sales of organic food in the United States, for example, went from under $200 million in 1980 to $1.5 billion by the early 1990s to over $10 billion by 2003 and $17.8 billion in 2007. Organic foods are now about 3 percent of all food sales in the country. The growth rate is so strong that some predict organic sales will approach 10 percent of total U.S. food sales within a decade. Parts of western Europe are already approaching that figure—notably Denmark, Sweden, Finland, and parts of Germany.”

Geographies of Green Diets

With the discursive onset of “global warming” in the global lexicon, seemingly inconsequential personal choices are subject to questions of ‘Greenness’ (Green indicating an alternative that is better for the environment than the status quo).  In a world that is increasingly linked technologically, economically, and culturally in a complicated web of globalization, your diet (what you eat, not your weight loss plan) raises convoluted issues of scale, politics and environment that are not always so easy to comprehend.

Perhaps the most interesting characteristic of the questions behind a “Green Diet” is how geography is implicated in all aspects.  Whether this is a question of agricultural and land-use practices, of environmental problems or solutions, of scale from the local to global, or of socio-economic, culture or politics, each has a spatial component and consequence.

The United Nations International Panel for Sustainable Resource Management argues in a June 2010 report that, “Current patterns of production and consumption of both fossil fuels and food are draining freshwater supplies; triggering losses of economically-important ecosystems such as forests; intensifying disease and death rates and raising levels of pollution to unsustainable levels.”  The report calls for a controversial shift in global diets to reduce such environmental pressures.  This shift would be away from those including a large amount of animal-based products to those including more vegetable-based foods.  This report was certainly not the first to call for such a dietary shift, another contribution came from well-known author and activist, Michael Pollan who challenged readers to eat whole fresh foods, a little meat, and avoid processed foods.

Yet, after the UN-backed report, there seems to be a resurgence of dialogue over the greenness of our diets.  An author from the Atlantic asks, “Can Meat Eaters be environmentalists?” arguing that the two are not a contradiction.  She has also authored the New York Times article “The Carnivore’s Dilemma” researching the connection between meat and global warming.  An excellent Mother Jones article tackles the “merits of vegetarianism” by taking the question to a panel of experts and to readers, cheekily poised as “Bacon Lovers vs. Soy Huggers.”  This article is an outstanding source for both sides of the debate and includes plenty of interesting, albeit covert, geographical references from trophic structures to cultural preferences.  Another aspect of greening diets comes from the Local Foods movement, dubbed by the USDA as “Know your Farmer, Know your food”, which focuses more on where your food comes from rather that what you eat.  An NPR program and article offers a very interesting once over of the movement, but also of the economic and logistical challenges, combined with the overall reluctance of food distributors to make the change.

Overall, the underlying issues behind these questions have to do with various ‘costs’:  energy costs, food supply costs, economic costs, and environmental costs.  Each of these costs indicates difficulties that can be best understood in a holistic, interconnected way.  Indeed, geographers best understand the human-environment connections behind our diets:

-  How fossil fuel use may be translating into warmer climates;

-  How most crop agriculture is devoted to animal agriculture, creating fossil fuel and economic entanglements in between, and then topping it all off with the addition of more heat-trapping methane into the atmosphere;

-  How the economic networks associated with status quo crop and animal agriculture mean jobs, taxes, and livelihoods to large populations of Midwestern and Central United States;

-  How environmentally costly, both looking back and forward, commercial agriculture has been for native grassland ecosystems and rainforest ecosystems, freshwater supplies, and perhaps for climates throughout the globe.

Discussion Questions:

  1. Do you know where your food comes from or how it is produced?  When you are out at your local grocery store, favorite restaurant, school cafeteria, café, farmer’s market, etc. look for clues about where food products come from, how they are produced, and how they are delivered.
  2. What do you think about the arguments made in the “Bacon Lovers vs. Soy Huggers” article?  What conclusions can you draw about which diet is greener?  What are some further questions you might have?
  3. Think about the connection between food production (meat, vegetables, and processed foods) and climate.  List the various ways that production, distribution, and consumption contribute or neutralize effects on climate.

Concept Caching: Energy Needs in Japan

This image submitted by H.J. de Blij, exemplifies the great technological, economic, and environmental investment and consideration of global energy security.  A fitting complement to the news stories and Geography Compass article discussed in the post Geography Directions: Energy security.

Geography Directions: Energy Security

From our Geography Directions site reviewing Wiley-Blackwell’s Geography Compass review journal covering the entire discipline.  Keep up with cutting edge academic geography.  These articles may be useful for introducing students to the discipline or may be appropriate for upper division Geography classes.

Our dependence on energy is increasingly fragile. In the US, oil companies are drilling deeper and taking more risks in response to the demand for cheap oil. In April, a Transocean/BP oil rig in the Gulf of Mexico exploded and sank, resulting in a massive oil spill. Regardless of how the situation has been managed, it was the demand for oil that meant that the oil rig, with all its associated risks, was there in the first place. Energy supplied by fossil fuel is becoming more risky to obtain.

Meanwhile, on the Isle of Eigg, off the west coast of Scotland, residents have been urged to use household appliances less as a lack of rain has reduced the amount of electricity generated through hydro-power schemes. Energy supplies are becoming more difficult to sustain.

In Belarus recently, piped gas supplies from Russia were reduced in response to a disagreement over payment for gas and the use of transit pipelines. Energy security is therefore not just a case of the geographical distribution of supply and demand, but is also dependant on complex social processes and international relations.

Michael Bradshaw deals with these themes in an article in Geography Compass, published in 2009. Bradshaw illustrates the multidimensional nature of energy security. For example, climate change policy is driving a reduction in reliance on carbon-based fossil fuels. At the same time, China and India’s rapidly developing economies are increasing their demand for energy, reshaping the challenges of energy security as they add their voices to the debate.

Geographers are well placed to understand the interface of the physical and political drivers of changing energy supply and demand. A key challenge remains in translating this into an understanding of energy security and the policies needed to sustain affordable and sufficient energy supplies.
