My posts about agriculture tend to lean one of two ways. The first is to advocate for a dramatic, rapid increase in indoor food production. That includes the various forms of indoor farming, as well as efforts to cultivate edible bacteria and microalgae. The second is that for the land that’s currently being used for farm, we shift to a form of ecosystem management much closer to what Native Americans did prior to the European invasion. Land Back should be part of that, of course, but the basic idea is to cultivate an ecosystem that’s full of useful and edible organisms, and to treat it as a community resource, owned in common by everyone, for everyone’s benefit. As always, the exact specifics of this approach will vary depending on regional and local conditions.
I get that just swapping over would feel like a big change to most people. We’re very used to what “farming” looks like, and it can be hard to trust that something like bacterial flour or rows of plants under LEDs would be able to feed humanity in our billions. Fortunately, while I’m more interested rapid, radical change, my philosophy for making the world better is one where every step along the way should come with its own improvements. My favorite example is probably the use of plant life to mitigate air pollution. There’s ample evidence that being around greenery improves both our mental and our physical health (not that those are really separate things). We’d get pretty immediate benefits from adding plants to the urban landscape. Those improvements to our health and wellbeing give us more power, through better health and saved money, to fight for the next step up.
That’s why, while the vision in my head may be some sort of solarpunk permaculture utopia, there are actually much smaller steps that we could take, which would have measurable benefits, both in terms of dealing with climate change directly, and in terms of improving ecosystem health. For example, this study lays out what seems to be a sort of intermediary step, designed to capture carbon, improve ecosystem health, and reduce dependence on pesticides and herbicides, with relatively little effort:
The researchers conducted two independent experiments at the University’s research facilities at the Ruissalo Botanical Gardens in Turku. In the greenhouse and common garden studies, the research team showed that the intensity of mowing has a great impact on pastures. By reducing the intensity of the mowing and cutting the plant higher, the overall yield of the pasture increased and the plants developed bigger roots. This indicates a higher atmospheric carbon sequestration into belowground storage.
What was surprising, Fuchs emphasises, is that the researchers found a detrimental effect of herbicide residues in soil on root growth regardless of the intensity of the yield harvest.
“This demonstrates a tremendous limitation to the potential carbon binding and storage belowground when soils are polluted by pesticide. Considering the vast amount of pesticides applied to agricultural fields yearly, we can conclude that the impact on soil quality is a major driver of limited root growth, carbon sequestration, and consequently plant resilience and productivity,” Dr Fuchs says.
The authors propose additional field studies to extrapolate their findings onto a field scale. Both studies conclude that climate change mitigation via optimising carbon sequestration and storage in soil can be achieved by reducing pesticides, which will facilitate root growth and improve plant resilience.
All over the world, cultivated grasslands are used as grazing pasture as well as for growing fodder that is turned into hay and silage. They cover large parts of the world’s agricultural land and have a tremendous potential for climate change mitigation through carbon storage. The plants use carbon dioxide as they grow, and some of this atmospheric carbon becomes bound in the soils.
“Consequently, understanding how pesticide pollution in soil and intensive management limit plant productivity is the key to optimising intensive grassland-based agriculture in a sustainable and climate-friendly way,” Fuchs concludes.
Oh yeah, it means better crops, too. Did I bury the lede? Maybe a little. They don’t really talk about ecosystem health, but I think it’s pretty easy to see how less intensive mowing, and less pesticide use would both have a “side effect” of improving the general health of the area.
I think we should be ending most of our animal agriculture, which would eliminate much of the need for grasslands as fodder, but we’re not going to get there overnight, and anything we can do to improve things now will make our lives just a little bit easier down the line. Of course, that only matters if this research actually leads to a change in practice. It always comes back to that, doesn’t it? There’s something we could try to make the world better, but nobody in the aristocracy seems to feel like investing in it. That’s why I keep coming back to collective power and political change.
As I said at the beginning, the steps we take now can be both immediately beneficial to us, and beneficial to our ability to get bigger changes down the road. We’re not capitalists here at Oceanoxia, so don’t think in terms of “political capital”. The kind of power we on the left want to build isn’t something that’s lost when used. Each victory brings more people and power to the cause, and sets us up for an even bigger victory.
I think many of us are accustomed to witnessing a political and economic “ratchet” effect, in which Republicans use their power to damage things like the social safety net, and Democrats stabilize things, but don’t actually reverse the damage, or guard against further damage. I mean, the Dems do plenty of damage themselves, but we’re talking generalities. While we’ve made great advances in terms of civil rights (hence the current reactionary backlash), 9/11 ushered in a new era of authoritarian government power in the United States, coupled with a dramatic increase in the concentration of wealth and power in the hands of the ruling class. It’s discouraging, and often horrifying to watch.
The one bit of hope I’m offering today is that we can, by working together, create our own ratchet effect, whereby we can increase our own power and happiness, and lay the foundations of a much better future than what currently looms on the horizon.
