How the rise of the megacity is changing the way we live

How the rise of the megacity is changing the way we live | DSODE HSC Geography | Scoop.it
The rapid increase in the number of cities home to more than 10 million people will bring huge challenges … and opportunities... 

 

It's not just that more people now live in cities than in the rural countryside (for the first time in human history).  It's not just that major cities are growing increasingly more important to the global economy.  The rise of the megacities (cities over 10 million inhabitants) is a startling new phenomenon that really is something we've only seen in the last 50 years or so with the expectation that the number of megacities will double in the next 10 to 20 years (currently there are 23).  This reorganization of population entails wholesale restructuring of the economic, environmental, cultural and political networks.  The urban challenges that we face today are only going to become increasingly important in the future.

Kenny Dominguez's curator insight, December 12, 2013 12:26 AM

It is a good thing that there is more megacities being created because you can see more people move in which will help the city function better economics wise. When it comes down to the population that is a different story because there is more people to worry and deal with. The increase of people could go both ways because it can be good but at the same time it can go bad because people will start arguing in which it can get physical which means city ratings going down.

Ecotourism in Australia

Ecotourism in Australia | DSODE HSC Geography | Scoop.it

"Ecotourism strives to protect the native cultures and environments of destinations while entertaining and informing tourists of all ages. For many years people within the tourism industry have debated what destinations and practices truly qualify as ecotourism without reaching a definitive consensus."

The trend for Ecotourism is presented in this article with questions raised about what practises fulfil the requirements of truly ecotourism. Appropriate to the future directions of Tourism as a global economic activity.

Seth Dixon's curator insight, May 16, 5:04 PM

Ecotourism is an important aspect of Australia’s success. The Australian Government produced a website, that is dedicated to the tourism and ecotourism industry.  There is a debate of land claims between the Australian Government and indigenous people. The cultural difference plays a significant role in the success of ecotourism because tourists enjoy the cultural heritage. The separation has created social, political, and economic reasons to be involved or not in ecotourism. The Australian Government has developed certificates and policies to allow aborigines rights of their land.

Chris Costa's curator insight, December 1, 2015 4:27 PM

I have enjoyed the emphasis on the human aspect of geography in this course, and how geography impacts us. However, as much as the world influences us, we do have a substantial amount of influence on the composition of the planet, oftentimes for the worse. The Great Barrier Reef is one of the greatest wonders of the world, home to some of the most spectacular sights one can see; as someone who has been scuba diving a handful of times, I can only imagine what it must be like to explore such a world below the surface, seeing all the life that surrounds me. I would love to be able to at some point in my life, but there is a great probability that I might never get the opportunity, as the reef is dying- fast. 50% of the reef has been lost over the past 3 decades, and while Australia has pledged to reserve over a billion dollars to fund conservation efforts, it might be a case of too little, too late. Man-made climate change as a whole is taking a toll on one of nature's greatest treasures, and it might be out of the hands of the Australian damage to reverse the damage that has already been done. I would love to have the opportunity to see this one day, and I hope I get to, but I don't know if I ever will if current rates of reef loss continue. Here's to hoping humanity gets it act together and tries to save the geography we often take for granted; we won't like the ugly landscapes that will follow if we don't.

100 African Cities Destroyed By Europeans

100 African Cities Destroyed By Europeans | DSODE HSC Geography | Scoop.it

"When tourists visit sub-Saharan Africa, they often wonder 'Why there are no historical buildings or monuments?'  The reason is simple. Europeans destroyed most of them. We only have a few drawings and descriptions by travelers who visited the places before their destruction. In some places, ruins are still visible. Many cities were abandoned when Europeans brought exotic diseases (smallpox and influenza) which started spreading and killing people. Most of those cities lie hidden. In fact the biggest part of Africa history is still under the ground."

Chris Costa's curator insight, October 27, 2015 4:27 PM

The issues with poverty and hunger that grip certain parts of Africa- particularly the sub-Sahara- find their roots in the utter subversion and destruction of African societies and states during the Trans-Atlantic Slave Trade and the subsequent colonization of Africa. European traders placed significant strain of existing African states during the 14th and 15th centuries, as the emergence of "slave states" and the extent of the trade completely changed the demographics of much of Africa. Labor shortages lead to technological shortfalls as well as the dissolution of many African states, as predatory states continued to destroy many civilizations and cultures. By the time that the majority of the West had banned the trade in the 19th century, the damage had already been done; many of the great civilizations of Africa had regressed or been entirely wiped out under the pressure of Europe's demand for slaves. The subsequent colonization of the continent only worsened matters for the Africans, as major hubs of civilization were captured, raided, and destroyed. Traditional societies were subjected to European influences and religion and eventually lost, and yet Europeans looked at the destruction and the lack of economic and political progress their actions had caused and blamed it on the inferiority of the Africans themselves. History has not been kind to Africa, and it is important to remember that that is not her fault. Many civilizations, cities, and states were lost as a direct result of contact with Europeans during the slave trade and the subsequent colonization of the continent. 

Mark Hathaway's curator insight, October 30, 2015 6:34 AM

Before European contact, Africa had a number of great urban cities. European arrival foresaw the destruction of those once grand cities. The Europeans brought diseases such as smallpox and influenza to the African continent. Those diseases would hamper the previously unexposed African population. Slavery also drained Africa of millions of people as well. Great African civilizations were brought down by these various calamities. European  arrival was the death knell of the great African civilizations. Africa is still living with this legacy of destruction. Africa is the most rural region in the world, because of this legacy.

Gene Gagne's curator insight, November 4, 2015 4:07 PM

Just another way to eliminate any African culture or customs.

Living in the Age of Airplanes

Living in the Age of Airplanes | DSODE HSC Geography | Scoop.it

LIVING IN THE AGE OF AIRPLANES is a story about how the airplane has changed the world. Filmed in 18 countries across all 7 continents, it
renews our appreciation for one of the most extraordinary and awe-inspiring aspects of the modern world. The documentary is produced and directed by Brian J. Terwilliger (“One Six Right”), narrated by Harrison Ford, and features an original score by Academy Award-winning composer James Horner
("Avatar," "Titanic").

Sally Egan's insight:

This trailer for the film provides a wonderful overfiew of what aviation has done to chnage the world in which we live. Great stimulus for discussion relating to tourism as well as other aspects of globalisation. Encourage you to watch this trailer and then to see the entire film.

Mijnbouw en aardverschuivingen, een goede combinatie ...... 

PIRatE Lab's curator insight, April 7, 2014 11:48 AM

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough). 

 

View the impact in ArcGIS online: Before and After Swipe, LiDAR I and II, and Imagery.

 

Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?
