The True Size Of Africa

The True Size Of Africa | Ana Célia Vieira |

This is another old classic image that I might have shared earlier but it merits repeating. As Salvatore Natoli (a leader in geography education) once said, "In our society we unconsciously equate size with importance and even power." This is one reason why many people have underestimated the true size of Africa relative to places that they view as more important or more powerful.

Just a reminder

It is incredible big, but unfortunately most of the north area is cover by the big Sahara and most of the are is typically unfertilized.

As we can see, there's a little overlapping here and some empty spots but it's pretty accurate. The United States and China are in the top 5 largest countries of the world list and they still fit in the 2nd largest continent of the world, Africa. I'd like to see the size comparison between Africa and Russia. I did some research on that and it turns out that Russia is a little over half the size of Africa, maybe the size of the combination of the United States and China.

Education - EarthWatchers video tutorial (HD)

Students can participate in monitoring the forests of Borneo by signing up for Earthwatchers.  Each student is assigned a parcel of land, and through the use of satellite imagery, identify and mark changes in land patterns over a period of time. These changes are shared with relevant local authorities, who will then investigate any deforestation in that area.

Here's how it works: 

Each Earthwatcher is allocated a piece of land to monitor (hexagonal 1.6km2) Periodically new image is provided by radar satellite data providers allowing Earthwatchers to compare images and look for changes / disturbances. Earthwatchers report disturbances from within the program and collaborate with their neighbours, who hold the land around their hexagon, to explore whether or not the disturbance is related to illegal activity. Intelligence is sent directly back to the data center and information is shared with local authorities.......
