Six months after the explosions at the Fukushima nuclear plant and the release of radiation there, Professor Jim Al-Khalili sets out to discover whether nuclear power is safe. He begins in Japan, where he meets some of the tens of thousands of people who have been evacuated from the exclusion zone. He travels to an abandoned village just outside the zone to witness a nuclear clean-up operation.
Professor Iain Stewart uncovers the mysterious history of Australia, and shows how Australia's journey as a continent has affected everything from Aboriginal history to modern day mining, and even the evolution of Australia's bizarre wildlife, like the koala.
All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.
In the shadow of Italy?s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. An eruption could endanger the millions of residents of the city of Naples. Scientists gain new insights into what happened in nearby Pompeii, and dig into the unique geology of Campi Flegrei. How will they know if the ever-shifting ground is reaching a breaking point? And can an innovative eruption warning system prevent Naples becoming the next Pompeii?
The semantics of the model I'm working from use common goods/common property/ common pool resources (resources used by multiple people) and common property regimes (the institutions or social arrangements between people, the property rights regarding common pool resources).
