From plastic to pavement: Another example of creative waste management

You cannot imagine my surprise while reading a BusinessWeek article last July about an innovative way to transform India’s litter into partial substitute for bitumen in asphalt to build roads!

Well, this transformative method arguably holds larger potential than the “garbage to music” recycling approach I recently wrote about in my first post about creative ways to manage waste. “Garbage to roads”  was pioneered by an Indian chemist called Vasudevan, and it could help not only in getting rid of tons of plastic litter- thick acrylics and bottles, grocery bags and wrappers-- but in building roads at the same time. It’s a win-win solution for all.

Have Humans Evolved to Manage Megacities?

The growth of large metropolitan areas around the world has been very recent and very rapid, particularly when measured against the duration of human beings’ existence as a species. For the first 95% of our time on earth, we built no settlements at all. Cities of a million people arose during only the last 1% of homo sapiens’ time on earth, and there are already 500 such cities in the world today.

If we have spent most of our existence as small wandering bands, does that mean we are ill-equipped to manage urban settlements of this vast size? The key to success in our current urban transformation may in fact be the same as the key to mankind’s earliest origins - our ability to cooperate.

It’s Not the How; It’s the Why

Hardly a week goes by without my hearing the statement, “It’s not the What; it’s the How.”  On the reform of energy subsidies in the Middle East and North Africa, for instance, the discussion is focused not on whether subsidies should be reformed (everyone agrees they should be), but on how the reform should be carried out.  Similar points are made about business regulations,educationagriculture, or health. I confess to having written similar things myself.  And there is no shortage of such proposals on this blog
 
Reforms are needed because there is a policy or institutional arrangement in place that has become counterproductive.  But before suggesting how to reform it, we should ask why that policy exists at all, why it has persisted for so long, and why it hasn’t been reformed until now.  For these policies didn’t come about by accident.  Nor have they remained because somebody forgot to change them.  And they are unlikely to be reformed just because a policymaker happens to read a book, article or blog post entitled “How to reform…”

 Requests and Appeals

More than 95 countries have laws that grant citizens right to information held by public bodies.These laws are commonly referred as the right to information (RTI) or freedom of information (FOI). The international community recognizes citizens’ ability to access public information as a human right.

Quote of the Week: Raghuram Rajan

Central bankers have had enormous responsibilities thrust on them to compensate, essentially, for the failings of the political system. And my worry is we don’t have sufficient tools to do that, but we’re not willing to say it. And, as a result, we push as hard as we can on the existing tools, and they may create more risk in the system.” 

- Raghuram Rajan, Governor of the Reserve Bank of India since 4 September 2013. Prior to his post at the Reserve Bank of India, Rajan was chief economic adviser to India's Ministry of Finance in 2012 and chief economist at the International Monetary Fund from 2003 to 2007.
 

Open Government Contracts Platform is now live!

More than 60 governments have committed to the Open Government Partnership (OGP), making their government data available to enable public scrutiny and citizen monitoring, and enhance government accountability. The Open Contracting community is devising Open Contracting Data Standard to enhance disclosure and participation in public contracting processes. In the U.S., the GovLab at New York University developed an OpenData500 project that has an interactive visualization of how U.S. companies are using government data for new business opportunities. It’s all a good start.

Despite all these developments on opening up data interaction, a critical question remains: how can we make sure that governments disburse public resources to those that need it most, and that public contracts are allocated in a transparent, accountable and efficient manner?
