What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Land- And Water-Grabbing Increasing Worldwide

What's the Latest Development?

A study done by the University of Virginia and the Polytechnic University of Milan is the first-ever assessment of efforts by corporations to "grab" land and water in other countries for agricultural use. Sixty-two countries, most of them in Africa and Asia, have experienced land- and water-grabbing by entities from 41 other countries, most of them in the Middle East, Southeast Asia, Europe, and North America. In most cases, says study co-author Paolo D'Odorico, "there is a switch from natural ecosystems -- such as forests and savannas -- or small-holder agriculture run by local communities, to large-scale commercial farming run by foreign corporations."

What's the Big Idea?

The study attributes the increase in land- and water-grabbing to an increase in global food prices that took place in 2007-2008. While at least one positive aspect is cited -- corporations have the technology to make better use of the land and provide employment opportunities -- many more negatives are mentioned. Most notably, says D'Odorico, "[b]y losing control of part of their land and water...local people are giving up to wealthier nations their most precious natural resources -- resources that could be used now or in the future to enhance their own food security." The study is published in the current Proceedings of the National Academy of Sciences
