In a move that will benefit the environment, farmers are placing increased emphasis on the quality of their soil and cutting back on ploughing. It took a kind of soil evangelist to create the revolution.

Erica Goode has the story at the NY Times.

“Gabe Brown is in such demand as a speaker that for every invitation he accepts, he turns down 10 more. …

“Mr. Brown, a balding North Dakota farmer who favors baseball caps and red-striped polo shirts, is not talking about disruptive technology start-ups, political causes, or the latest self-help fad.

“He is talking about farming, specifically soil-conservation farming, a movement that promotes leaving fields untilled, ‘green manures’ and other soil-enhancing methods with an almost evangelistic fervor.

“Such farming methods, which mimic the biology of virgin land, can revive degenerated earth, minimize erosion, encourage plant growth and increase farmers’ profits, their proponents say. And by using them, Mr. Brown told more than 250 farmers and ranchers who gathered at the hotel for the first Southern Soil Health Conference, he has produced crops that thrive on his 5,000-acre farm outside of Bismarck, N.D., even during droughts or flooding.

“He no longer needs to use nitrogen fertilizer or fungicide, he said, and he produces yields that are above the county average with less labor and lower costs. ‘Nature can heal if we give her the chance,’ Mr. Brown said.” More here.

Sounds like wisdom that even a backyard farmer could embrace.

There’s been a lot in the news lately about water shortages in the West. In the search for any help they can get, some concerned citizens are turning to the oft-maligned beaver.

Living on Earth‘s Steve Curwood gets to the bottom of the story with Sarah Koenigsberg, the filmmaker behind The Beaver Believers.

“In the drought-ridden West, some people are partnering with beavers to restore watersheds, where, before trappers arrived, the large rodents once numbered in the millions. Filmmaker Sarah Koenigsberg captures various efforts to reintroduce beavers to their former habitat in her documentary The Beaver Believers and tells host Steve Curwood why beavers are essential for a healthy ecosystem. …

Koenigsberg: We feature the stories of a biologist, a hydrologist, a botanist, an activist, a psychologist and a hairdresser. So these are all very different people who share the common passion of restoring beaver to the west. Some work within the federal agencies, the forest service, others are just average citizens who stumbled upon to the cause accidentally …

“What struck me with all of these beaver believers is that they are working on the problem of water, which is one of the biggest problems of climate change, but is very tangible. They’re working at the level of their own watershed. And while they do work very hard, they’re finding great joy and satisfaction in this work. …

Curwood: There’s a finite supply of water in the drought-ridden American west. Beaver can’t increase that water supply. What can beaver do to help the water situation? …

Koenigsberg: What they do is they redistribute the water that does fall down onto the landscape, so if you picture spring floods — all that water that comes rushing down in March or April just goes straight through the channels and out to the ocean — what beavers do is they almost act like another snowpack reserve, whether it’s rain or snow runoff, all of that water can slow way down behind a beaver pond and then it slowly starts to sink into the ground. It stretches outward making a big recharge of the aquifer and then that water ever so slowly seeps back into the stream throughout the rest of the spring and summer as it’s needed so that we end up with water in our stream systems in July and August when there is no longer rainfall in much of the west.” More here.

“How will the world find the water to feed a growing population in an era of droughts and water shortages?” asks Fred Pearce of Yale Environment 360 by way of the Christian Science Monitor.

“The answer, a growing number of water experts are saying, is to forget big government-run irrigation projects with their mega-dams, giant canals, and often corrupt and indolent management.

“Farmers across the poor world, they say, are solving their water problems far more effectively with cheap Chinese-made pumps and other low-tech and off-the-shelf equipment. Researchers are concluding that small is both beautiful and productive.

“ ‘Cheap pumps and new ways of powering them are transforming farming and boosting income all over Africa and Asia,’ says Meredith Giordano, lead author of a three-year research project looking at how smallholder farmers are turning their backs on governments and finding their own solutions to water problems. …

“Such innovations are becoming a major driver of economic growth, poverty reduction, and food security, says her report, “Water for Wealth and Food Security,” published by the International Water Management Institute (IWMI), a research center based in Sri Lanka.

“The report says better support for this hidden farmer-led revolution could increase crop yields threefold in some places …

“But such help could be a while coming, because much of the revolution is happening out of sight of governments and international organizations. In Ghana, the study found, small private irrigation schemes cover 185,000 hectares – 25 times more land than public irrigation projects. ‘Yet when I asked the agriculture minister there about these schemes, he hadn’t even heard of them,’ says Colin Chartres, director of IWMI.”

Living on Earth, a radio show based in Somerville, Massachusetts, and distributed by Public Radio International, recently did a story on East Africa and the worst drought in 60 years. Bobby Bascomb interviewed musicians who decided to do something about it, letting their voices be heard in the way they know best.

They call themselves the Caravan of Hope, says Bascomb. “More than 25 bands from 11 different African nations are traveling across the continent to raise awareness about climate change … as international climate talks begin in Durban, South Africa.”

Singer Angella Katatumba of Uganda explains, “We use our voices to get people fired up and educate people about climate change in Africa. Uganda usually has an amazing climate. It’s usually warm and just perfect. These days, when it’s hot it’s way too hot. When it’s cold it’s way too cold. When it’s wet, it’s storming. We’re seeing things like landslides, which we’ve never had before.” So she’s taking her concern on the road. Read more here.
