A little while back there was an announcement that anyone who could solve the world’s dead zone problems like we have in the Gulf of Mexico here in the U.S., could win a million dollars. Instantly, I thought my ship had come in, because I knew the answers to the challenge right off the top of my head. It would take me five minutes to do an outline, an hour to write it up, then, bang, a million bucks and I’ve bought my way into New Zealand. But then I caught the clincher “solutions must meet a suite of simultaneous and sometimes conflicting needs – from protecting water resources and near-shore ecosystems to ensuring the capacity and vitality of agricultural productivity” — at which point I gave up without trying. Appropriately, the contest comes out of Tulane University, based in New Orleans, Louisiana.
For starters, how I’d love to see a minimum natural area bordering all waterways, scaled to the size of the waterway. But, why is it that when something makes such obvious sense, then, it just cannot happen? Look at this from George Monbiot excerpted from his lengthy rant against corporate agriculture yesterday over at The Guardian:
We should turn the rivers flowing into the lowlands into “blue belts” or “wild ways”. For 50 metres on either side, the land would be left unfarmed, allowing trees and bogs to return and creating continuous wildlife corridors. Bogs and forests trap the floodwaters, helping to protect the towns downstream. They catch the soil washing off the fields and filter out some of the chemicals which would otherwise find their way into the rivers. A few of us are now in the process of setting up a rewilding group in Britain, which would seek to catalyse some of these changes.
Fifty metres is only 164 feet. Along the mighty Mississippi, we should have at least 2-5 miles of natural forest and prairie land — so George is being really conservative in his baby step plan.
There is good news today in industrial farming practices as they relate to the Dead Zone. There is less overuse of fertilizers, and precision agriculture and cover crops are helping.
But we need a wiser long-term vision, a vision which would bring back a healthy biodiversity to the Midwest. I’d like a lot of shelter belts to return to farming areas, “agroforestry” if you will; and, wildlife corridors which would run up and down the former prairie lands which would be available to the public for enjoyment and help to attract a vibrant younger population back to the Midwest; and let’s throw in a minimum percentage of taxpayer-funded natural land, or buffer strips, on every farm, too. By removing tiling from beneath buffer strips, those areas could actually catch fertilizer run-off. Finally, we could turn more of corn country into grasslands on which to raise large herbivores, and other livestock. All of these things could really help to reduce the Dead Zone… but what will NOT reduce the Dead Zone is the monoculture crop status quo.
The U.S. Midwestern industrial agriculture farmer ails economically today from the monoculture commodity oversupply problem. We have not gained export market share of our major three commodity crops (corn, soybeans, wheat) in fourteen years (see graph). This land which is polluting the Dead Zone due to fertilizer runoff is not, unfortunately, feeding the world. No, it is feeding our cars and the end-points of crony capitalism.
Are these things feasible? Yes, anything is feasible given the right policy support… over time.
Unfarming. Now that’s a word for this century.
