Climate Food and Agriculture

This one will hit harder in the global south

Climate change is affecting the oceans in any number of unpredictable ways. For example, under pressure from rising ocean temperatures (and toxic waste), coral reefs — those glorious engines of biodiversity — are degrading. I knew that. But this one was new to me: They also become breeding grounds for poisonous algae. And that poison […]

Fisheries biologist’s work revealed extent of loss of oceanic fishes

From the Washington Post:

Ransom A. Myers, 54, the world-renowned fisheries biologist whose research showed that the number of large fish in the world's oceans has dropped by 90 percent in the past 50 years, died of a brain tumor March 27 at a hospital in Halifax, Nova Scotia.

The journal Science has just published a major paper co-written by Dr. Myers, "Cascading Effects of the Loss of Apex Predatory Sharks from a Coastal Ocean," about the importance of sharks in marine ecosystems. There is an abstract of the paper on the Science website.

More than any other scientist, Ransom's work has alerted us to the full extent of the rapid decline in fish populations in recent years, particularly large pelagics and other predators.

Not — yet, anyway

I know there are Gristmill readers with high hopes for algae-based biofuels. They will enjoy this piece in Popular Mechanics. Here’s the hope: Solix addresses these problems [algae’s finicky growing habits] by containing the algae in closed “photobioreactors” — triangular chambers made from sheets of polyethylene plastic (similar to a painter’s dropcloth) — and bubbling […]

We need to rethink all food based biofuels

The lion's share of biofuel bashing on Grist deals with corn ethanol, because we Americans primarily use gasoline for our cars and ethanol runs fine in them, with few modifications. However, our pals in Europe drive a lot of diesel cars and the biofuel crisis over there revolves primarily around biodiesel. I think it is time we recognize that their problem is also our problem. A comment from Pcarbo alerted me to Monbiot's latest take on biofuels. He has now gone so far as to propose a ...

... moratorium on all targets and incentives for biofuels, until a second generation of fuels can be produced for less than it costs to make fuel from palm oil or sugar cane.

The Daily Show on cloned meat:

The perils of cooking with greenhouse gas.

The BBC has issued a pretty clear-eyed report on food production and climate change, the podcast of which you can download here. The report makes no brief for sustainable ag, but it does cogently question industrial ag’s ability to “feed the world” as climate change saps water tables and population continues to grow.

Now’s the time to discover the myriad pleasures of growing food

“A natural diet lies right at one’s feet.” — Masanobu Fukuoka, The One-Straw Revolution It’s springtime here on my mountain farm, and that means an explosion of activity. We’re starting seeds in one greenhouse, and finishing construction on another. Fields are being tilled, and we’re putting in the very first sugar-snap peas and spring onions. […]

Don’t Make Me Pull This Cargill Over

Amazon soy export plant shut down in win for environmentalists Greens did a victory dance this weekend as Brazil forced U.S. agribiz giant Cargill to close a soy export terminal in the country’s Amazon region. The facility has long been the focus of a targeted Greenpeace campaign protesting rapid deforestation of the tropical rainforest — […]
