Rose Goslinga: Crop insurance, an idea worth seeding


Across sub-Saharan Africa, small farmers are the bedrock of national and regional economies—unless the weather proves unpredictable and their crops fail. The solution is insurance, at a vast, continental scale, and at a very low, affordable cost. Rose Goslinga and the Syngenta Foundation for Sustainable Agriculture pioneered an unconventional way to give farmers whose crops fail early a second chance at a growing season.

TED Fellow Aziza Chaouni recounts her 20 year effort to restore this river to its former glory, and to transform her city in the process.

Tim Berners-Lee: A Magna Carta for the web


Sir Tim Berners-Lee invented the World Wide Web 25 years ago. So it’s worth a listen when he warns us: There’s a battle ahead.

Eric Liu: Why ordinary people need to understand power


Far too many Americans are illiterate in power — what it is, how it operates and why some people have it. As a result, those few who do understand power wield disproportionate influence over everyone else. “We need to make civics sexy again,” says civics educator Eric Liu. “As sexy as it was during the American Revolution or the Civil Rights Movement.”

Joi Ito: Want to innovate? Become a "now-ist"


“Remember before the internet?” asks Joi Ito. “Remember when people used to try to predict the future?” In this engaging talk, the head of the MIT Media Lab skips the future predictions and instead shares a new approach to creating in the moment: building quickly and improving constantly, without waiting for permission or for proof that you have the right idea. This kind of bottom-up innovation is seen in the most fascinating, futuristic projects emerging today, and it starts, he says, with being open and alert to what’s going on around you right now. Don’t be a futurist, he suggests: be a now-ist.

Paul Bloom: Can prejudice ever be a good thing?

Simon Anholt: Which country does the most good for the world?


It's an unexpected side effect of globalization: problems that once would have stayed local—say, a bank lending out too much money—now have consequences worldwide. But still, countries operate independently, as if alone on the planet. Policy advisor Simon Anholt has dreamed up an unusual scale to get governments thinking outwardly: The Good Country Index. In a riveting and funny talk, he answers the question, "Which country does the most good?" The answer may surprise you (especially if you live in the US or China).
