Thanks to Humans, the Great Salt Lake Is Drying Up

Thanks to Humans, the Great Salt Lake Is Drying Up | Geography Education | Scoop.it
Diverting more water could pose serious health and economic threats to Utah.
Seth Dixon's insight:

Follow-up: The drying up of the lake can't be blamed on the current drought, this is a human-induced modification of the environment.  This lake is not exceptional, even if the imagery is startling.  Like many lakes in dry climates with growing populations, the people are using the freshwater flow into the lakes more extensively than they have in the past.  The Great Salt Lake, the Aral Sea, Lake Chad, Lake Urmia, and the Dead Sea are all drying up.

Teagan M's curator insight, April 21, 9:13 AM
Date: April 21think that we should stop using up the lake and keep it as is because any more damage could cause it to be totally destroyed and potentially bad for the economy. Protecting the lake is the best thing they could do right now, but Any more damage and they might never be able to make it go back to the way it was, and it could stay dry forever.
Mary Grace Bunch's comment, April 21, 10:21 PM
The Great Salt Lake in Utah is drying up which will lead to an unpromising future for the environmental health of the area. This is occurring due to the consistent reductions from rivers feeding into the lake that have been taking plays for 150 years. This past year the Great Salt Lake reached record low levels, dropping 11 feet. As a result of this increase in salinity and loss in half the volume of the lake, there is going to be trouble involving the economy and ecology of the state of Utah. This can be seen by dust storms or pollution.

The agglomeration of these rivers and gateways into the lake for human use are leading to the backwash effect. The backwash effect can be seen as the drained/dried out of water, an important resource to Salt Lake City, being drained in its regions. The impacts of the rivers outside of the lake are affecting the resources of the lake, even though it may not seem direct. Primary Economic Activities such as fishing will be impacted by the drying up of the Great Salt Lake. As a result of this, the development of Utah will be threatened. Utah is very reliant on the lake for it’s valuable resources that help them develop. A solution may be found through ecotourism. If the city is motivated in solving this problem, they could very well promote ecotourism in order to preserve the lake since Salt Lake City is very popular and many people travel there.

This article was relative to the Development Unit we are in now. It made me aware of what is going on in Utah. I never would have known this issue was occurring until I took the time to read it. I look forward to following along with this issue in the future and to see how the state of Utah will deal with it.

Utah's Great Salt Lake is shrinking

Utah's Great Salt Lake is shrinking | Geography Education | Scoop.it
Human activity is playing a role in the dwindling size of Utah's Great Salt Lake, according to new research.While the research group acknowledged the role that climate fluctuations, such as droughts and floods, have played in the shift of the lake's water levels over time, the decrease in the lake's size is predominantly due to human causes. According to the report, the heavy reliance on consumptive water uses has reduced the lake level by 11 feet and its volume by 48 percent.

Seth Dixon's insight:

The railroad causeway that creates the color difference between the northern and sotuhern portions of the Great Lake is as the Union Pacific plans to change the causeway; the proposed bridge would allow for the two distinct salinities to intermingle more.  Environmentally, this lake is not exceptional.  Like many lakes in dry climates with growing populations, the people are using the freshwater flow into the lakes more extensively than they have in the past.  The Great Salt Lake, the Aral Sea, Lake Chad, Lake Urmia, and the Dead Sea are all drying up.

Living Bridges

"In Northeast India just north of Bangladesh is the province of Meghalaya."

Seth Dixon's insight:

The living bridges of Meghalaya are truly sights to behold; these astonishing bridges are a natural way that local people have adapted to an incredibly flood-prone environment.  The organic building materials prevent erosion and keep people in contact during times of flood.  Here is another video and articles (BBC, Atlas Obscura, Inhabitat, and MNN) with more ecological and cultural context on these living bridges.

Climate Change Is Here

Climate Change Is Here | Geography Education | Scoop.it
Record heat, fading ice, and rising seas show how climate change is affecting us. But there’s new hope we can cool the planet. Here’s how.
Seth Dixon's insight:

The National Geographic Magazine has recently created this interactive to accompany the magazine article on climate change (for those worried that the editorial direction would not be as environmentally focused because of the recent changes for the National Geographic Society, I think this is a resounding way for them to emphatically declare that they are committed as ever to their core values and mission).  This interactive is richly-laden with videos, images and case-studies, showing the tangible impacts of climate change and lays out what the future implications of these changes.  The interactive is organized to answer these main questions:

  • How do we know it’s happening?
  • How do we fix it?
  • How do we live with it

Sarah Cannon's curator insight, November 25, 2015 10:15 AM

There is too much talk about helping the climate and environment. All politicians do is talk about cleaning the environment and having less pollution. Even Al Gore is big talk. I've only heard of little change. I want to see a difference. I want to see people actually doing things to help the environment. Enough talk. What should happen is a world wide clean up. Jobs should be created where people should clean in their own community. Its a simple job. Get a trash bag, get off your lazy butts, get out of the house, get a group together (who would be paid by the state) to pick trash up off the streets, beaches, trails in the woods, baseball fields, parks. This isn't hard to do. Not just one person, but if a group of people can come together and be employed by their state to clean their community, at least four days a week. There should also be a group of people, even fisherman to clean the ocean, go out and get what ever trash you can find. Using nets, and if fish are caught, throw them back in the ocean. Also, Trash Island has to be eliminated. It boggles my mind that who ever passed the law on trash being dumped into the ocean an Okay to do. Are you kidding me?? What is wrong with you? Our Earth is dying because of humanity. Also the oil spill that happened in 2012, I believe, I saw a man on the news that created a way to capture the oil floating on the surface of the ocean with a blanket like material, sure it would take a lot of those "blankets" but at least it would be helping to rid the ocean from oil. What are people thinking?? that the oil will just disappear?? Are you serious? So many people really have to open their minds. Look at what's happening you ignorant selfish fools. I will finish my rant right here.

When China Rules the Sea

When China Rules the Sea | Geography Education | Scoop.it
The United States is no longer the world’s only global naval power.


Why would China go to the trouble and expense of mounting an expedition to the northern climes in the Western Hemisphere? Because it sees value in staging a presence in distant waters. And because it can: Beijing no longer depends completely on its oceangoing battle fleet to ward off threats in China’s seas. It can now rain long-range precision firepower on enemy fleets from land. Ergo, the People’s Liberation Army Navy (PLAN) fleet can cruise the far reaches of the Pacific and Indian oceans or even beyond, without forfeiting China’s interests in waters close to home.  For China, the upsides of far-ranging maritime strategy are many and compelling, the downsides fewer and fewer.

Mark Hathaway's curator insight, November 24, 2015 7:07 AM

The nation that controls the seas, controls the world. Throughout history the leading Naval powers have always been the worlds most dominate nations. The greatest land forces, are no match for the supremacy of the seas. Not even Napoleon could beet back the power of a supreme navy( The British Royal Navy). Since the end of the Second World War, The United States navy has dominated the seas. That domination has made the U.S the worlds greatest nation over the course of the past 75 years. For China to displace the U.S atop the nations hierarchy, they most out due us on the seas. China is ware of this history, and that is why they are heavily investing in their naval technology. The key to the future, as it has been in the past, will be what nation can dominate the worlds seas.

Benjamin Jackson's curator insight, December 13, 2015 8:23 AM

the growing strength of the Chinese navy is worrying from a military perspective, as during the cold war one of the main reasons they were not considered as big a threat as the Russians was because of their inability to project force beyond mainland china. with their navel improvements this is no longer the case. what this will hold for the future, we can only wait and see.

The Ogallala Aquifer

The Ogallala Aquifer | Geography Education | Scoop.it
Hidden beneath the 245,000 square miles that make up the Great Plains, resides a lake that’s one of our greatest water assets: The Ogallala Aquifer. Haven’t heard of it? Farming the plains would be unprofitable at best without it, as shown by the Dust Bowl of the 1930s. At the time, the aquifer’s existence was known, but the technology to tap into it wasn’t.
Seth Dixon's insight:

Portions of the High Plains Aquifer are rapidly being depleted by farmers who are pumping too much water to irrigate their crops, particularly in the southern half in Kansas, Oklahoma and Texas.  This podcast explores the environmental and economic impacts of this unsustainable situation.

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake | Geography Education | Scoop.it

"It's difficult to comprehend the ridiculous amounts of water that have fallen in such a short time in a state that, until recently, had been in the grip of a historic drought. But one place to start would be to look at reservoir levels in the state. In the past 30 days, Texas reservoirs have gone from being 73 percent full to 82 percent full, according to data maintained by the Texas Water Development board. All told, about 8 million acre-feet of water have flowed into the state's reservoirs."

Seth Dixon's insight:

Just how much of water is 8 million acre-feet?  It's almost impossible for most people to visualize that, but this series of graphics is designed to put the scale of the recent flooding in Texas into perspective (and yes, I love that Rhode Island is almost a unit of measurement).

How to fix California's drought problem

How to fix California's drought problem | Geography Education | Scoop.it
California has enough water—that's not the problem, says Terry Tamminen. So here's how you solve the drought crisis.
Seth Dixon's insight:

There is no easy fix to a complex problem such as the water shortage in California.  Some coastal cities are considering desalinization projects while others want to reduce environmental regulations that protect wetland ecosystems to harness all of the freshwater available.  One of the issues is that most of California's precipitation occurs during a very short time frame.  Before the water crisis, these potential flood waters were diverted into concrete management canals but this article advocates to build more underground cisterns to capture excess rainfall before it flows to the ocean.

Eden Eaves's curator insight, May 24, 2015 5:50 PM

The sunny state of California does in fact get enough rain fall each year but because storm sewers were built after continuous flooding, all of this rainfall is pushed into the Pacific Ocean rather than where it it needed now.

A solution to the insane drought taking California by storm is to use simple rain barrels to collect water at a typical home and a graded lawn to capture and retain water, allowing it to seep into the ground rather than run off into the streets and eventually into the ocean. 

Lydia Tsao's curator insight, May 25, 2015 2:20 AM

The article relates to irrigation and the conservation efforts discussed in Unit 5. Irrigation has a lot to do with the drought in California because massive amounts of water are being used for agriculture in California, which consists of water-needy fruits and vegetables. There are efforts to try to conserve water by installing rainwater collectors to reuse water instead of just draining usable rainwater to the ocean and rivers. There have also been installations of grey water pipes to reuse for irrigation. Grey water is any water that is flushed down the drain that isn't sewage, such as water from showers or water from washing machines. This way water wouldn't have to be wasted and can be reused.

This is always amazing to me when countries create these islands in the middle of the sea.  I remember when Dubai was doing this a few years back thinking that something like this was crazy and would never keep up.  China is smart by doing this because it feels it can control the S. China Sea if they have areas set up all over it.  I can see why surrounding countries that share the Sea's borders are pissed off at China because they should not have more right's to the Sea than any of them.  But what are/can they do about it?  If you mess with China, you are asking for trouble.

Brian Wilk's curator insight, April 30, 2015 8:43 AM

My research paper is on China and I'm adding topical China stories to it. This is just another example in an endless procession of questionable land grabs by the Chinese. They should not be allowed to play poker, they are really bad at hiding what they really want. China wants to add land for a simple reason; extending their military reach so they can dominate the region. It pushes out their boundaries to enable them to strike their enemies with relative ease. Missiles that fly 400 miles, planes that need refueling after 300 miles are now strategically placed on these islands to form a sphere of commanding  influence in Asia and beyond. If they were to use it to extend their fishing rights to feed their burgeoning population that would be almost diplomatic. China bears watching....

The Marshall Islands Are Disappearing

The Marshall Islands Are Disappearing | Geography Education | Scoop.it
Most of the 1,000 or so Marshall Islands, spread out over 29 narrow coral atolls in the South Pacific, are less than six feet above sea level — and few are more than a mile wide. For the Marshallese, the destructive power of the rising seas is already an inescapable part of daily life. Changing global trade winds have raised sea levels in the South Pacific about a foot over the past 30 years, faster than elsewhere. Scientists are studying whether those changing trade winds have anything to do with climate change.

Mark Hathaway's curator insight, December 12, 2015 6:21 AM

Climate change is a controversial issue in the United States. The debate over climate change in our current political environment is stuck in a denial or belief stage.  It is foolish to deny that our climate is changing. The overwhelming majority of scientists have provided the world with data, that proves that man is altering the climate. Those who deny climate change, probably do not really believe that it is not occurring.  They are denying climate change, because they do not favor altering our economic system in an attempt to stop the phenomenon. To really effect climate change, major changes are going to have to be made in the way we consume our energy. Our current political environment cannot and will not implement these changes. As with most problems, nothing will be accomplished until a large swath of Florida is underwater.

China's Maritime Claims

ONE reason China’s spectacular rise sometimes alarms its neighbours is that it is not a status quo power. From its inland, western borders to its eastern and southern seaboard, it claims territory it does not control.
Seth Dixon's insight:

Many of the geopolitical conflicts in the East Pacific have their roots in the territorial disputes over islands that at first glance seem as if they wouldn't be worth the trouble; how did this become a tense situation?  Since the UNCLOS agreement gives countries 200 nautical miles off their coasts to be an Exclusive Economic Zone, that greatly enhanced the strategic value of controlling these islands and the shipping lanes.  The United States, to counter Chinese claims, has used the Navy to go near some of the claimed (and reclaimed) islands recently.  This interactive map briefly highlights some of the details behind the conflicts with links for further readings. 


Questions to Ponder: Why do countries care so much about some minor islands?  Why would other countries not want to accept China's territorial assertions?

Chris Costa's curator insight, November 25, 2015 3:06 PM

Chinese expansion into the South Sea has been a longtime coming, and China's actions in the region are both a reflection of its growing strength and a huge diplomatic headache for the US and every other nation in the region. China's construction of artificial islands allows it to claim autonomy over a larger body of water, challenging the maritime power of every other nation in South East Asia, many of whom have economies reliant on the waters China now claims as its own, some 500 miles away from the Chinese mainland. With the emergence of the Chinese economy as a global power, its ambitious leaders have made plans to transform China from a regional military force to a new superpower- one that the established order, the US included, is entirely unsure of. Which of these nations can truly challenge China's decision to make these waters it's personal pond? It would be economic and political suicide, as China is an enormous global trading power, and has the potential to crush any of these nations in a military engagement. Could Japan? Perhaps, but the Chinese have already pressed ahead with their plans, regardless of Japanese political pressure. Involvement of the US is perhaps the last thing anyone wants- particularly both the US and China- but it is perhaps the only way China will heed pressure from abroad and cease  Chinese expansion in the region. The US and China must be allies, for the sake of global prosperity, but actions like these cannot be tolerated, by either party.

Gene Gagne's curator insight, December 1, 2015 7:51 PM

One reason to care about minor islands is the 200 nautical miles off the coast for the EEZ. This would give china more water territory for drilling of oil which I believe is there in those waters. Flexing more muscle for their navy to grow. Strategically the Chinese could take over these small islands and build air strips for future which would give them a chance to reach places they wouldn't be able to before and this would be good supply transactions during war, fueling, maneuver of man power. The other small countries also would lose their independence and would have to fall under china's rule. With the building of the man made islands and the Chinese navy protecting their people while they continue to build these islands and daring anyone to try and stop them is a sign that china is trying to dominate and expand with muscle. It is their time they have the economic, and military power to do so. Of course they don't want to deal with the u.s. and their allies militarily but it doesn't benefit the u.s. either. I don't believe u.s. wants to get involved in a battle with china and their allies.

Adam Deneault's curator insight, December 14, 2015 8:17 PM

Claiming territory it does not control, causes a lot of controversy with other country. The main problem here now is China is having a dispute with Japan about some islands. There could possibly be oil or natural resources.Japan says that the land was always theirs. China clearly likes to just put itself out there and make claims or place oil rigs wherever. This could be a big problem for them because if someone gets too offended by their actions there could end up being a war or some sort of conflict. Especially since they like to use military forces such as navy and air guarding "territory."

The world’s largest dam was created to generate more energy for China’s ever-expanding economy and to increase the interior economic development by increasing the navigability of the river.  The dam also can control downstream flooding and protect important industrial centers such as Shanghai.  This ambitious hydroelectric dam produces the same amount of energy as 18 nuclear power plants.  This dam also displaced over 1 million people as the reservoir flooded properties upstream.  The Three Gorges Dam prevents the nutrient-rich sediments from being deposited downstream; this heightens Chinese farmers’ need for fertilizers, this has led to drought downstream and limits residents’ water access. The dam also disrupted the local ecology (part of the reason the Yangtze River Dolphin went extinct), preventing fish to migrate to upstream breeding grounds. 

For good and ill, the dam has profoundly modified the environment and this video animation from NASA is a powerful demonstration of the changes.

Inland water - environmental change 

Benjamin Jackson's curator insight, November 9, 2015 5:40 PM

The impact of the Three Gorges Dam on the residents upstream is amazing. I cannot imagine anything like this happening in the US, mostly because of the impact on the people both upstream and downstream. Ecological damage from this dam may not phase the Chinese government, but I think any North American or European government would shudder at the thought of the backlash among their citizens this would create.

Matt Ramsdell's curator insight, December 14, 2015 9:27 PM

Three Gorges damn in China is the largest dam ever constructed. This was created to save on power by creating hydroelectric power for the people of the land. One of the issues with this was the the flooding of the land up streams displacing millions of people. It created a larger up stream area and very small down stream. A lot of the people that lived up stream had to be relocated further inland and faced changing climatif weather. The banks of the river are carved out between what seems like mountainous regions so as you move more uphill the weather and temperature will be a whole new category of life (Depending on how far you relocated).

How being surrounded by water made the Dutch different

How being surrounded by water made the Dutch different | Geography Education | Scoop.it
While researching a book on ‘Why the Dutch are Different’, Ben Coates realised that an amazingly large number of the things which an outsider might think of as ‘typically Dutch’ could be explained at least in part by a single factor: water.
Seth Dixon's insight:

Cultural, political and economic patterns of a region are heavily influenced by the environmental settings.  Occasionally though, geographers can get overly-cautious when discussing how the environment can shape culture, worried about straying into realm of environmental determinism.  However, environmental factors can profoundly influence cultural attributes.  This article shows how Dutch cultural attributes such as diet, history, politics and landscape are influenced by their maritime physical setting.

Tsunami Animation

"The largest earthquake ever recorded by instruments struck southern Chile on May 22, 1960. This 9.5 magnitude earthquake generated a tsunami that crossed the Pacific Ocean, killing as many as 2000 people in Chile and Peru, 61 people in Hilo, Hawaii, and 142 people in Japan as well as causing damage in the Marquesas Islands (Fr. Polynesia), Samoa, New Zealand, Australia, the Philippines, and in Alaska's Aleutian Islands.  To see how this tsunami compares with two recent tsunamis from Chile, please watch http://youtu.be/qoxTC3vIF1U "

Seth Dixon's insight:

In 1700, Japan was hit by a tsunami; they knew that tsunamis were caused by earthquakes, but there was no earthquake of that magnitude in Japan that could have caused it.  They called it the Orphan Tsunami, and it puzzled everyone.  Centuries later, data confirmed that a massive earthquake in the Pacific Northwest occurred in 1700 and it's tsunami traveled across the ocean much like the this computer simulation of the 1960 Chile earthquake.

Lawn Order

Lawn Order | Geography Education | Scoop.it

"In communities across America, lawns that are brown or overgrown are considered especially heinous. Elite squads of dedicated individuals have been deputized by their local governments or homeowners’ associations to take action against those whose lawns fail to meet community standards."

Seth Dixon's insight:

This is a great podcast from 99 Percent Invisible that shows not only the environmental aspects of America’s obsession with well-manicured lawns, it also nicely explored the cultural norms that police our behavior to create the stereotypical suburban landscape.  This is my favorite quote from the podcast: “There’s a paradox to the lawn. On the one hand, it is the pedestal on which sits the greatest symbol of the American Dream: the home, which people can ostensibly govern however they wish. And yet—homeowners often have almost no control over how they should maintain their lawn. Grass may be a plant, but a lawn is a designed object.”

What the Earth would look like if all the ice melted

We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century.

Digging In: Land Reclamation and Defenses in the South China Sea

Digging In: Land Reclamation and Defenses in the South China Sea | Geography Education | Scoop.it
The U.S. Department of Defense’s latest assessment of the Chinese military provided new detail on China’s land reclamation efforts on several of the islets that it occupies in the South China Sea. These include Fiery Cross Reef, Gaven Reef, Johnson South Reef, Mischief Reef, and Subi Reef in the Spratly archipelago. By December 2014, the report estimated that China had reclaimed as much as 500 acres of new land, creating full-fledged islands where only coral reefs or sand spits existed before. Since then, China has only accelerated its efforts, expanding the total land area that it has reclaimed to 2,000 acres and building military facilities, ports, and at least one airstrip on the islands.
Seth Dixon's insight:

We've heard in the news recently that China is reclaiming land from the South China see to presumably construct an air strip to strengthen their claims in the region.  China is not alone in this...

By doing so, China is not only digging land, but also preparing futur heavy discord. It's so strange : China critisize US hegemony and try to balance it. As result, China is having the same agressive attitude that US Bush era. Of course, not using bombs, but "pacifically" invading south China Sea.

Gene Gagne's curator insight, December 1, 2015 8:15 PM

I was wondering with the world being 80% ocean how much ocean can be transformed into land with these man made islands. Once again creating military strategic posts.

Kiribati and Climate Change

You might not be feeling the effects of climate change, but Kiribati, a small country in the Pacific, is actually drowning because of rising sea levels. Check out how the government there is trying to run a country that might not exist in a few years.
Seth Dixon's insight:

The impacts of climate change might feel far off or something that will affect other places...not so for the citizens of Kiribati.  This video is the 1 minute version of the political/environmental situation, and this is the 15 minute version.

The people who do not agree that Climate change is real, need to look further than their own neighborhoods for proof that it is real. This really blew me away. Entire island populations that have to relocate to other islands, as their home island of Kiribati continues to sink lower and lower until you are walking in water when the high tide comes in? Imagine that the highest reference point on your island or chain of islands is your town's dump? What is positive about these people's plight is that they are being trained professionally in much needed fields, and second is that they are openly welcomed to other nearby islands. Fred Issa,

Benjamin Jackson's curator insight, December 14, 2015 12:15 PM

this is an example of a small, innocent nation being hit harder by something caused by large nations which are having no negative impact on them. these large nations will not take responsibility until they must face the same results as Kiribati.

Adam Deneault's curator insight, December 14, 2015 10:07 PM

The video explains how the volcanic island will eventually disappear. The reason that the island will disappear is because of erosion and the sea is eating away at it. What makes them so easy to erode is the fact that the volcanoes are no longer active. Soon, coral reefs that are created will be the only thing holding the island together. Most of the island will be destroyed eventually and what is left behind will be in the shape of a caldera.
