A GM & Pesticide Free Rice Growing Revolution

Rice farmers have been growing their crop in the same way for hundreds of years and most people have assumed the most efficient way to grow rice has been figured out. That is until some farmers in India decided to change how they grow their bounty and now scientists have take note of their success.

What happened in Darveshpura has divided scientists and is exciting governments and development experts. Tests on the soil show it is particularly rich in silicon but the reason for the “super yields” is entirely down to a method of growing crops called System of Rice (or root) Intensification (SRI). It has dramatically increased yields with wheat, potatoes, sugar cane, yams, tomatoes, garlic, aubergine and many other crops and is being hailed as one of the most significant developments of the past 50 years for the world’s 500 million small-scale farmers and the two billion people who depend on them.

Instead of planting three-week-old rice seedlings in clumps of three or four in waterlogged fields, as rice farmers around the world traditionally do, the Darveshpura farmers carefully nurture only half as many seeds, and then transplant the young plants into fields, one by one, when much younger. Additionally, they space them at 25cm intervals in a grid pattern, keep the soil much drier and carefully weed around the plants to allow air to their roots. The premise that “less is more” was taught by Rajiv Kumar, a young Bihar state government extension worker who had been trained in turn by Anil Verma of a small Indian NGO called Pran (Preservation and
Proliferation of Rural Resources and Nature), which has introduced the SRI method to hundreds of villages in the past three years.

Video Games to Help the World

A game based on the story Half the Sky puts players into a perspective usually different than their own: a young girl in the developing world. It teaches young gamers in the developed world empathy and what it’s like to be a young girl trying to make a living in the majority world. It’s always nice to see games being used to make the world a little better.

If you succeed at certain tasks, the game triggers donations through partner charities. For example, the game has donated a quarter-million books. Players can also use real money to purchase virtual items — and that money has brought in more than $450,000 in charitable donations.

Since it launched nearly a year ago, more than 1.1 million people have played Half the Sky. Though that’s nothing compared to a game like Farmville, still it makes Half the Sky one of the most successful advocacy games.

The Hanging Gardens of Singapore

The Hanging Gardens of Ancient Babylon was known for it’s amazing vertical garden and to this day it’s not clear how the gardens functioned (or how it was built). That hasn’t stopped enterprising architects in Singapore from creating a modern version of the hanging gardens in skyscraper form!

Designed by WOHA, the block-long “hotel and office in a garden” sits on a narrow plot that opens onto Singapore’s central business core and is situated across from a verdant parkland and near the riverbank. Slab-like towers, which echo those rising in downtown just in the distance, are suspended above a green zone of tangled flora and palm trees that thrive in the tropical climate. The vegetation is rooted to curved terraces that are themselves fixed to the towers’ glass facades. “The project is a study of how we can not only conserve our greenery in a built-up high-rise city centre but multiply it in a manner that is architecturally striking, integrated and sustainable,” the architects say.

Nifty Looking Glow in the Dark Paths

Saving energy is always a good thing, and sometimes that means turning out the streetlights. As a result, pathways go unlit and this can be problematic for cyclists and pedestrians. Enter a new surface treatment that glows in the dark for free night time illumination known as Starpath.

Seeing that local city councils were increasingly shutting off park lights at night to save money, Pro-Teq developed Starpath to maintain public safety without the financial and environmental costs of overhead lighting. It’s a common problem; in the U.S. for instance, cities generally count streetlights as their first or second biggest energy drains.

But the glow-in-the-dark spray also comes with additional benefits: Its non-reflective surface doesn’t seem to contribute to light pollution, which not only inhibits views of the nighttime sky, but can have dire consequences for local wildlife due to the constant illumination.

Overhead street lighting does provide one important benefit to urban parks, however, and that’s the deterrence of crime. It’s not yet known if Starpath would provide enough light to do the same.

Changing Car-Based Infrastructure for Walkable Communities

The suburbs are designed for cars as opposed to people and this is a problem that has surprising side effects from personal health issues to an increase in violent deaths. So how do we modify the suburbs to stop these side effects? In this TED talk, Jeff Speck explores what can be done.

How do we solve the problem of the suburbs? Urbanist Jeff Speck shows how we can free ourselves from dependence on the car — which he calls “a gas-belching, time-wasting, life-threatening prosthetic device” — by making our cities more walkable and more pleasant for more people.
