In a project that will be watched by engineers and biologists across the nation, construction crews today will begin a three-year, $84 million project to tear down the hulking San Clemente Dam in Californias largest dam-removal project ever.
Imagine if one day the power goes out on a nationwide scale, the water stops running and becomes scarce. How will you survive? Start thinking about collecting water from the atmosphere, there is over three quadillions of it floating around the...
Water has become a risk rather than an opportunity in our cities and that must change.
At Ecobuild, Professor Tony Wong, chief executive of the Cooperative Research Centre for Water Sensitive Cities, spoke about the steady progression up the agenda of water sensitive urban design (WSUD) in Australia. Successive years of flooding and some of the worst droughts in history have threatened the health and wellbeing of the population and nearly brought industry grinding to a halt, prompting the government to think differently about water.
A new report published in March reinterprets the WSUD concept and its concludes: for too long, we have been designing water out of our cities when we should have been designing it in.
For example, sustainable drainage systems (SuDS) – the creation of ponds, wetlands, swales and basins that mimic natural drainage – can be a cost-effective way to prevent surface flooding while creating valuable public amenities. But we need to go further and join the dots between flood risk management and water resource management, and put water at the heart of discussions about what makes places great to live...
Not only will you learn about hurricanes but you can also watch videos about lighting, tornadoes, volcanoes, and overall everything about the weather. These are great videos to use in class when teaching units about natural disasters. These videos are full of great engaging facts.
I absolutely loved watching these videos. I believe they would be a fantastic resource to show students or for students to use for research when exploring natural disasters. This site provides multiple videos on multiple different disasters. Each video provides great information and facts including, causes, when and where they are most likely to happen, the amount of damage, different sizes and speed and past examples. Each video provides such great visuals and explanation for these natural disasters. Students would be able to gain deep knowledge and understandings to support their research and/or investigation. I am currently in the middle of creating a task for my students using digital technologies such as this and incorporating collaboration through Wikis and blog. I plan to use these videos to further my students knowledge and encourage further exploration on these videos for their research.
Located entirely within the Atlantic Ocean, is the only sea without a land boundary (nice little trivia tidbit--Its shifting borders are defined by ocean currents). So if these waters are a part of the Atlantic Ocean, then why do these waters deserve their own name? What is distinct about the Saragasso Sea?
Fearing that climate change could wipe out their Pacific archipelago, the leaders of Kiribati are considering an unusual backup plan: moving the population to Fiji.
How urgent is the issue of climate change? That question is not only geographic in content, but the response might also be somewhat contingent on geography as well. If your country literally has no higher ground to retreat to, the thought of even minimal sea level change would be totally devastating.
This shows one of the worst consequences of climate change, large scale migration. If sea levels continue to rise, millions of people will be displaced and other countries will have to take in these environmental refugees. Climate change will directly and indirectly impact the geography of the world. Population geography will be drastically altered when areas like Kiribati are wiped off the map.
The people of Kiribati are facing trouble with their archipelago and are considering moving their population to Fiji. Kiribati straddles the equator and is facing severe climate change with many areas rising about sea level. Many of the population has already moved and the increase in sea levels has contaminated the fresh water supply. Kiribati is close to Fiji but there is a major concern on where all of their population will live if making the move. Kiribati is relatively poor and government is trying to purchase land in Fiji to secure their people's safety.
Do you think that you have problems? Review the problem that the people on the Island of Kiribati have right now. Their paradise island is slowly sinking into the ocean, and will leave these people without homes, and livelihoods. Imagine you entire world as you know it slipping below the waves one tide at a time. This is the very real problem that the citizens of this island paradise has right now. The good news is that the people of the Island of Fiji have invited the people from this and other islands to migrate to their island. At a time in our world when refugees from Syria are being turned away from being allowed to escape from the murder machine known as ISIS, this is a welcome sign. I hope the peaceful people of the Island of Kiribati find new safe homes and occupations in Fiji. Fred Issa,
Environmental degradation, seasonally high rainfall, a low elevation profile and climate change combine in a very bad way for Bangladesh. Flooding, given these geographic characteristics, is essentially a regular occurence. For a more in-depth look at these issues from the same media outlet, see: http://www.youtube.com/watch?v=Wj0iZiivYJc&feature=player_embedded#!
The "socio-economics of flooding" is a side of the natural disaster we don't normally think about. People most affected by floods tend to live in areas with poor infrastructure and large populations. Their displacement to cities, like Dhaka, has incredible cost. For both the family and the new place they relocate to.

The four pollutants — black carbon, methane, ozone and hydrofluorocarbons — all cycle through the atmosphere more quickly than carbon dioxide, which lasts for centuries in the troposphere, the part of the atmosphere we live in and breathe. Carbon dioxide is the main culprit in Earth's warming temperatures, which impacts sea level rise both by the expansion of water as it warms and by the melting of glacial ice.
Cutting the air pollutants, which all also act to trap heat in the atmosphere and last anywhere from a week to decade, worldwide by 30 to 60 percent over the next several decades would lower predicted sea level rise by 22 to 42 percent by 2100, according to the study, published April 14 in the journal Nature Climate Change.

Pressure on the world's resources is becoming so great the situation could trigger a proliferation of hunger and warfare hugely damaging to the global economy, according to an analysis published today.
ALBUQUERQUE — The muddy Rio Grande isn't much to look at as it meanders through southern New Mexico to the Texas border, but its waters are a high-stakes prize in a new legal row unfolding between the neighboring states.
The collapse of the Aral Sea ecosystem is (arguably) the man-made environmental disaster of the 20th century. Soviet mismanagement, water-intensive cotton production and population growth have all contributed the overtaxing of water resources in the Aral Sea basin, which has resulted in a the shrinking of the Aral Sea--it has lost more of the sea to an expanding desert than the territories of the Netherlands, Belgium and Luxembourg combined. The health problems arising from this issues are large for the entire Aral Sea basin, which encompasses 5 Central Asian countries and it has profoundly changed (for the worse) the local climates.
This has to be one of the most telling video of an environmental disaster I have even seen. A whole sea, 26,000 square miles, bigger than the state of West Virginia, is bascially gone due to Soviet mismanagement. This is an environmental disaster now that the Russians do not have to deal with as it is now located in the independant country of Kazakhstan. It effects them as well as the new countries that have come to be withthe collapse of the USSR. Seems Russian dodged this just like Chernobyl. This is something we need to lean from, on how not to use a natural resource until it literally has dried up.
The Aral Sea, located in Central Asia is a very important water source for the entire region. Unfortunately, the Soviet Union designated this water sources as one which would provide water to rice and cotton crops, which are both very water-intensive crops. This has resulted in desertification of the area due to the cyclical shrinking volume of the lake. Sands and chemicals are now free to blow around, affecting people's health. This is one of the best examples on earth of environmental exploitation due to a lack of environmental planning. When the lake dries up, the inhabitants of the surrounding countries will be in huge trouble.
The Aral Sea was a source of food for the residents, as it was home to thousands of fish and water was used to irrigate crops.Also acted as a climate regulator. Therefore, its virtual disappearance has caused winters and summers are extreme.Today the drought is considered one of the greatest ecological disasters caused by man. scientists estimated that the Aral sea will disappear before 2020. A plan to expand the cultivation of cotton throughout Central Asia and thus a system of canals for irrigation that significantly decreased the amount of water reaching the Aral Sea. It angers me to see that the human has being causing many natural disasters.
"Competition for increasingly scarce water in the next decade will fuel instability in regions such as South Asia and the Middle East that are important to U.S. national security, according to a U.S. intelligence report."
Geographic thinking is about uncovering the spatial connections between issues that on the surface might not seem related. Multinational river basins are a perfect example of environmental resources that demand international cooperation for successful management, and it regions of scarcity and population growth, it is easy to envision clashing viewpoints on how to fairly share such resources.
Discussion questions: What geographic themes are evident in this article? What geographic problems could exacerbate the problem? What could alleviate these issues in the future?
Water is a huge resources and obviously something that we use everyday and in the US take for granted because there are many countries suffereing from sortages such as this nation. Which of the following it is threatening not just the stability of the nation but the stability of the people and the society that make up that nation.
A community in Bonsaaso, Ghana learns that their local water supply contains unsafe mineral concentrations. See how they implement a filtration system design...
Ghana is one of the more stable nations in the region, and yet even it has serious issues with fresh water. This video shows how low-tech solutions can combat the tainting of water by environmental factors such as mineral contamination of water sources. The $5,000 price tag for such technology seems high, but is very affordable considering the benefits given. Another organization working on this issue is: http://waterwellsforafrica.org/
This video shows a water filter created by an engineer from Ghana and members of the community talking about how much the filter has helped them. The chemicals in the water made it unsafe to drink but this filter purifies the water to make it safe.
