Roads to ruin: The devastating impacts of the global infrastructure explosion

From an environmental perspective, we may be living in the most frightening times since a giant meteor wiped out the dinosaurs and many other species some 65 million years ago.

But rather than extraterrestrial devastation, today's tsunami of change is entirely of our own making.  And perhaps no change is of greater importance than the astonishingly rapid explosion of roads and other infrastructure globally. 

As ALERT director Bill Laurance highlights in two hard-hitting editorials this week -- one in the International New York Times and another in New Scientist -- the pace and magnitude of change is truly unprecedented.

For example, in the next few decades, we can expect to see some 25 million kilometers of new paved roads, some 3,700 additional hydroelectric dams, and tens of thousands of new mining and fossil-fuel projects.

In just the next 15 years, investments in new infrastructure projects could approach 70 trillion US dollars -- more than doubling infrastructure investments globally.

Many of these projects will penetrate into the world's last surviving wilderness areas, opening them up like a flayed fish.  Since 2000, for instance, the Congo Basin has been crisscrossed by over 50,000 kilometers of new logging roads.  This has opened up the Basin to poachers armed with rifles and cable snares, who in turn have killed off two-thirds of the global population of forest elephants.

We urge you to read the two brief editorials above, and share them with your friends and colleagues.  There is still time to avoid a global calamity -- but only if we act with a true sense of urgency.

ALERT scientists tell G20 leaders to stop the 'infrastructure insanity'!

This has been a big week for ALERT. 

In the Amazon, 95% of all deforestation occurs within 5 kilometers of a road  (Google Earth).

On March 5, the top-ranked journal Current Biology published a hard-hitting paper -- led by ALERT director Bill Laurance and including ALERT member Tom Lovejoy, former environmental advisor to three U.S. presidents -- that the G20's plan for infrastructure expansion bordered on ecological insanity.

In case you haven't been following this story, during its meeting late last year in Australia, the G20 leaders -- who lead the world's 20 biggest economies -- pledged to invest $60-70 trillion US dollars globally in new roads, hydroelectric dams, power lines, gas lines, mines, fossil-fuel projects, and other infrastructure over the next 15 years.

To put that number in perspective, the current value of all infrastructure across the entire planet today is roughly $50 trillion

So, we're talking about more than doubling the amount of global infrastructure in a very short period of time.

Nobody is denying that the world needs better and more infrastructure -- especially developing nations trying to improve their economic and social conditions.

But to subject the planet to an unprecedented tsunami like this is almost unfathomable.  The environmental consequences -- the impacts on nature and native ecosystems -- simply boggle the mind

One bit of good news is that the Current Biology paper is being used as the scientific foundation -- by scores of the world's top scientists, environmental leaders, and other luminaries -- to lobby the G20 leaders to back down from their pledge to hyper-drive global infrastructure

The paper lays out nine specific recommendations to help make infrastructure projects environmentally safer and more sustainable.  It's no magic bullet, but if taken seriously these recommendations could make a real difference.

Let's hope the G20 listens.  If they don't, they'll be guilty -- and this is no exaggeration -- of promulgating the worst environmental calamity in human history.
