Border Walls

Border Walls | Chris' Regional Geography |

"Geographer Reece Jones discusses his recent book Border Walls, examining the history of how and why societies have chosen to literally wall themselves apart.  He gives a brief history of political maps, how international lines reshape landscapes, and how the trend towards increased border wall construction contrasts with the view of a “borderless” world under globalization."

chris tobin's insight:

This broadcast states how advances in cartography over time maps borders of territory that became public in europe since the 180's, before that places to travel to were only by memory.  After WWII orders were recognized and redrawn.  Maps and borders organizes land around us as fixed territories to control.  It allows territories control over their land and authority.  Less than 5 borders or fences shortly after WWII existed and now there are at least 50 ,75% which are within the last 70 years.  Physical walls being built slows human travel, borders wealthy from poor--US/Mexico has one of the largest gaps where US GDP is greater by 4 to 1 compared to Mexico (US$40,0000

Mexico $10,000 us dollars)  India/Bangladesh border also illustrates this.  They share the same Bengali languge, with 15 million Bangladeshis living and working in India.  This border is 4000 km long with 200,000 border agents employed.  The border fence is about 10 ft high doubled barbed with many gates and flood lights (no camerastation in space because of the flood lights).  Bangladesh cross into India to visit relatives living there, and work.  Bangladesh has poor standards of living and India has increased standards of living.  Bangladesh has over 160 million people , 1238 people per sq km (dense population) in the comparable size of US state of Iowa, is a low lying area with floods, (Ganges River empties into Bay of Bengal) and as sea levels rise one meter flooding occurs.

The future of borders between $$wealthy and poor and world trade capital movement ,investments of US in other countries and trade of other countries into the US, and the poor becomes a threat to the territories (states, countries) sine they cannot move around in the world.  Morre walls and fence borders are to com.  In the last 15 years walls and fences has increased between countries to protect resources and control their area and even used strategically to their own advantage for resource control, political control and military advantages while affecting the environment, economics and peoples way of life.

This is a must read book which has won Geography awards and very insightful.

listening to some of the podcast you can get an in-depth synopsis of this. the walls that divide our countries and even towns over time have all the criteria and/or reasoning. Great Wall of China to keep invaders from starting war, Berlin Wall to divide german supporters of war, America/Mexican boarder is to keep illegal immigrants from coming, fence in your moms backyard is to keep neighbors/animals out of yard. Walls all have the same concept of avoiding war, trespassers and privacy. this is seen in not only everyday living but in military use as well.
