YALE ENVIRONMENT 360

In its quest to find new sources of energy, China is increasingly looking to its western provinces. But the nation’s push to develop fossil fuel and alternative sources has so far ignored a basic fact — western China simply lacks the water resources needed to support major new energy development.

For decades, farm bills in the U.S. Congress have supported large-scale agriculture. But with the 2012 Farm Bill now up for debate, advocates say seismic shifts in the way the nation views food production may lead to new policies that tilt more toward local, sustainable agriculture.

From the rainforests of central Africa to the Australian outback, indigenous people armed with GPS devices are surveying their territories and producing maps they can use to protect them from logging and other outside development.

For four decades, Amory Lovins has been a leading proponent of a renewable power revolution that would wean the U.S. off fossil fuels and usher in an era of energy independence. In an interview with Yale Environment 360, he talks about his latest book, which describes his vision of how the world can attain a green energy future by 2050.

The long-held contention that rural forest communities are the prime culprits in tropical forest destruction is increasingly being discredited, as evidence mounts that the best way to protect rainforests is to involve local residents in sustainable management.

Twenty years ago, an historic environmental summit in Rio de Janeiro produced groundbreaking treaties and high hopes that pressing issues would be addressed. But as organizers prepare for the Rio+20 conference in June, there is little on the agenda to suggest any substantive action will be taken.

While U.S. action on climate change remains stalled, four south Florida counties have joined forces to plan for how to deal with the impacts — some of which are already being felt — of rising seas, higher temperatures, and more torrential rains.

The Japanese government is launching a large-scale cleanup of the fields, forests, and villages contaminated by the Fukushima nuclear disaster. But some experts caution that an overly aggressive remediation program could create a host of other environmental problems.

More than a billion people worldwide lack access to electricity. The best way to bring it to them — while reducing greenhouse gas emissions — is to launch a global initiative to provide solar panels and other forms of distributed renewable power to poor villages and neighborhoods.

The language in Journey of the Universe is something that is deeply dependent on scientific discoveries. It’s not using any kind of overt religious language. But it is suggesting, what are the grounds for environmental concern and ethics and action? We are not naming it from any particular perspective — it’s an evocation more than a preachment.
