Safe drinking water disappearing fast in Bangladesh

Safe drinking water disappearing fast in Bangladesh | #georic | Scoop.it
Extreme weather increases salinity of water in coastal areas while excessive demand in Dhaka leaves dwindling supply

Via Seth Dixon
Tony Aguilar's insight:

too much salt in water and little technology to desalinize can be an issue caused by poor resources and natural conditions. Another issue is industrializastion and how that can increase polution to local waters as little regulations increase there and globalization is a factor that has opened up many jobs in bangledesh.

For over 20% of the population, finding safe drinking water in Bangladesh is a daily struggle that is only expected to worsen in the coming decades.These Bangladeshis live in "hard-to-reach" areas of the nation, along the swampy marshlands of the inlands and coastal outlets, where access by roads is severely restricted. This makes it difficult to transport the necessary aid to these regions, placing them disproportionately at the peril of natural disasters and other such catastrophes. The increasing salinity of the water in these areas- the result of acid rain and other man-made climate changes- has made it extremely difficult for the people of these regions to find the drinking water necessary to replenish their exploding population. With the effects of climate change only worsening, the plight of these people can be expected to get worse and worse. Millions of people face increasing health risks and even death as we move forward into the 21st century; I hope that the powers that be are able to find a solution to help these people receive the aid they so desperately need. 

Mark Hathaway's curator insight, November 10, 2015 6:34 AM

Water is essential to human survival. Contaminated water is a detriment to human survival. Extreme weather has caused a dwindling of the safe drinking water supply in Bangladesh. The consequences of this dwindling are catastrophic.  A lack of safe drinking water will inevitably lead to the demise of many people. Warfare is often a consequence of a lack of precious resources. No resource in the world is more precious than water. This issue was caused by extreme weather increasing the salinity of water in the costal areas. Physical geography plays a huge role in the availability of safe drinking water. Areas more prone to extreme weather are far more likely to experience these same kinds of issues. Unfortunately, Bangladesh in one of those areas that is effected by this type of scenario.  

Sarah Cannon's curator insight, December 14, 2015 10:04 AM

Access to safe drinking water is a physical and human geography issue because it all depends on location. For example, in Dhaka, a heavily populated area, fresh water is limited. Besides waters/rivers in Dhaka being polluted, this is a poverty filled area and government funds can only get so much for people. Dhaka is a poor, urban, and populated community.

'Absolute Bedlam' In The Philippines After Typhoon Haiyan

'Absolute Bedlam' In The Philippines After Typhoon Haiyan | #georic | Scoop.it

The news from the Philippines, where it's feared that last week’s powerful Typhoon Haiyan killed more than 10,000 people, isn’t getting better as hundreds of thousands of people struggle to survive and authorities struggle to get help to them.

 

"Its absolute bedlam right now," says Richard Gordon, head of the Philippine Red Cross.  “There's an awful lot of casualties, a lot of people dead all over the place, a lot of destruction.”

 

According to the BBC, a huge international relief effort is underway, but rescue workers have struggled to reach some towns and villages cut off since the storm.

Tony Aguilar's insight:

people have  not slept normally for days. There hasnt been one person who hasnt lost someone in the devastation. THe government of the Phillipines is doing all they can for help. one woman is asking for international help to come not tomorrow but as soon as they possibly can. It is absolute chaos. There are villages that have been cut off from public assistance, and the international community is pulling together now to help bring relief. People are with signs asking the world for help.

Even though the death toll resulting from Typhoon Haiyan is around 1,000, it is expected to reach 10,000.  International aid will hopefully help cities such as Tacloban City recover from this storm.

Jack Born's curator insight, November 14, 2013 9:16 PM

This is insane. It has affected millions of people and and even killed people. Its good that so many people are going to help though.

Tracy Galvin's curator insight, May 3, 2014 7:05 PM

With so many of the citizens living on the coast, a large typhoon like this completely destroys most of the country. When this much devastation happens all at one time it takes a very long time to recover.

Inside the Colorado deluge

Inside the Colorado deluge | #georic | Scoop.it

"Two things that helped make this rainfall historic are breadth and duration. Colorado can get much higher rainfall rates for brief periods and over small areas."


Via Seth Dixon
Tony Aguilar's insight:

      What was interesting about this particular deluge was how much rain fell and how it happened in such a short time. Meteroligist high wet density levels of vapor that rose to high altitutdes and was able to condense into water and help in a perfect combination of weather to create a powerfully dangerous flash flood.

    The article recounts a former major colorodo flood that occured in 1978 and had killed over 150 people during a centenial celebration.

   After this occurence warning signs were put up beside the roads to warn travelers of flash flood possiblities and to promote safety. These floods do not happen in Colorado often and are usually a surprise. They do not when the nextmajor flash flood may occur in the boulder region but they know through historical patterns that it will happen again. 

This article stood out to me because I have friends that live in these areas and had to run for safety and move their cars to prevent damage in these same areas. The good thing is that the people that I know from this area are doing ok.

Our thoughts are with our colleagues and friends in Colorado as they are dealing with the impact of this historic weather event.  The geographic factors that contributed to this flooding are explained in this article from the University Corporation for Atmospheric Research (UCAR).  Some are calling this a millennial flood, as it is well past the 100-year stage of flooding.  You may view the areas impacted on an ESRI storymap. and in this NASA imagery

The devastating flooding in Colorado has impacted so many. The rainfall Colorado has experienced makes it the most on record. The massive amounts of flooding and devestation in areas like Boulder are caused by the highly populated valley areas.  

Al Picozzi's curator insight, September 17, 2013 4:13 PM

Almost seems like a perfect storm scenario.  Large amouts of rain over a long perod of time over a large area.  This combined with a late summer/early fall heat wave and tons of moisture in the air, with climate change all contributed to the disater in Colorado.  They also believe the changes made by people to the physical geography over the last hundred years or somade have contributed to teh flooding in the area.  Development can effect the way a place floods.  Where there were once open fields and trees, there are now parking lots and houses which just can't absorb rainfall.  Makes you ask the question, shouldn't there be more study of where we exapnd our cities and what effect this will have in case of a major rainfall, earthquake, blizzard, etc?

The Philippines' Geography Makes Aid Response Difficult

The Philippines' Geography Makes Aid Response Difficult | #georic | Scoop.it

Via Seth Dixon
Tony Aguilar's insight:

The phillipines is made up of many islands, it is difficult to bring aid quickly and promptly. Disease may be an issue for the still unreached. Aid has come from all over world. and it was also stated that China was a bit stingy in it contribution to the disaster. Again this an important opportunity to increase effecient strategies in dealing with natural disasters and working together with the world at large in improving the speed and manner in which aid is distributed.

This is a devastating time for the people of the Philippines. All they have to worry about is staying alive and being close to there family members. Help is on the way. Everyone in the world should pitch in and try to help them in anyway they can. But what I would like to find out is why this has happen when it has not before in this country. This country I have not seen in the news before this big devastation had happened. I am also curious to find out how come the help aid is taking so long to arrive when people are dying because they have no food available for them because it has been destroyed or it is trapped under all the debris from all the buildings that have collapsed because they were not structured properly. this situation is a repeat of hurricane Katrina in the united states were all the house were not hurricane proof and were built in places known for disaster.

Joseph Thacker 's curator insight, April 19, 2014 10:37 PM

Due to the fact the Philippines is made up of over 7,000 islands, it makes aid response very difficult. When natural disasters such as typhoons occur in the Philippines it can negatively affect hundreds of islands, making it difficult to help the people on every island. It can takes days for supplies to arrive on some of the islands, and sometimes people do not even receive necessary supplies such as food and water. Countries, which are composed of numerous islands, face many challenges.  

Tracy Galvin's curator insight, May 3, 2014 7:09 PM

Fortunately, the Philippines has a relatively stable infrastructure so even though lots of areas were hit, the human fatalities and issues are not as bad as they could have been. Unfortunately, these are many islands and getting from one to the next is very difficult when all communications and landing areas are compromised.

Submarine Canyons

Submarine Canyons | #georic | Scoop.it

"Submarine canyons were identified by the pre-SONAR mappers, but it wasn’t until this technological advancement that we realized how common a feature they are. We now know that there are hundreds (perhaps thousands depending on your definition) of submarine canyons incising into continental shelves and slopes all over Earth."

Tony Aguilar's insight:

submarine canyons are a natural underwater phenomenon with no clear explainable cause. They are located in parts of the world sush as New Zealand and off the coast of Santa Monica california. These canyons at the bottom of the ocean may have been ancient rivers from before prehistoric times, and the erosion and subduction of the tectonic plates over millions of years leave the remains of channels of rivers from the past. Another theory is that they are caused by water forces that caused the sea bed to erode and make way for an actuall canyon. With the use of Sonar technology we are still discovering phenomons of the submarine world as sciene progresses. These canyons are common and are found all over the Earth and give is an understanding of what the world may have looked like long ago.
