"The International Database at the US Census Bureau [provides] population estimates broken down by country, age and year for essentially every country. [With this data we can track] shifts in population makeup over time. I’ve created a few interesting graphs to show the expected shifts over the next 35 years, including the dependency ratio."
The Landsat Data Continuity Mission is now Landsat 8, and that means images are now public (woohoo!). NASA handed control of the satellite to the USGS earlier this year (May 30, 2013), and calibrated imagery is available through the Earth Explorer. Unfortunately, the Earth Explorer interface is a bit of a pain, so I’ve put together a guide to make it easier.
Earlier this summer the T3G participants had an informal lightning talk session with many people sharing their favorite educational, geospatial or professional development tools. I was amazed as some of the incredible projects these fantastic educator are involved with and I didn’t have time to properly credit all the speakers, but this was the best I could do to capture some incredible projects. Below are some of the links:
UNHCR has been attempting to count the world's refugees since it was created. If you want to find out which years resulted in the worst displacement, which were the biggest countries of origin and which were the biggest countries of asylum, use the interactive map.
"By 2025, the developing world, as we understand it now, will be home to 29 megacities. We explore the latest UN estimates and forecasts on the growth of these 'cities on steroids', and take a look at the challenges and opportunities megacities present for the tens of millions living in Lagos, Mexico City and Dhaka."
"By 2030, two out of three people will live in an urban world, with most of the explosive growth occurring in developing countries. For a preview of the future, the last in the Challenges for Humanity series explores São Paulo, Brazil; Lagos, Nigeria; Bangkok, Thailand; and Hyderabad, India."
Humans have gained unprecedented supremacy over the seas in a short space of time, thanks to potent technological advances such as satellite tracking devices and engines so formidable they can drag nets big enough to engulf a cathedral. Add in the impact of pollution, from the likes of fertiliser run-off or discarded plastic, and the oceans have changed more in the past 30 years than in all of human history.
In most places, the oceans have lost more than 75 per cent of their “megafauna” – large creatures such as whales, sharks, dolphins, rays and turtles. Numbers of some species – oceanic whitetip sharks; American sawfish – are down by as much as 99 per cent. For every 20 leatherback turtles in the Pacific 50 years ago, only one remains...http://www.ft.com/cms/s/2/9601c144-9dcd-11e1-838c-00144feabdc0.html#axzz1vqzpHIBt
The Connected Smart Cities Portfolio Network has been established to provide an open and collaborative framework for smart cities to cooperate, network and share their experiences. This is a result of the FIREBALL project, which brought together three key communities, the Living Labs, the Future Internet research community and cities. This is supported by the European Network of Living Labs and EUROCITIES so please get involved by producing content, participating in events and active networking.
