How to practice sustainable agriculture
Lots of people confuse sustainable agriculture with organic farming. Both are aimed at using more ecologically sensible practices, but they are judged by a distinct set of standards. If you want to farm sustainably, there are certain measures you need to undertake in order to move toward that goal. And if you're looking for a farm that practices sustainable methods, then you can use these steps as your criteria.
Sustainable agriculture integrates three main goals:
- Environmental stewardship
- Sustainable farm profitability
- Prosperous farming communities
These goals have been defined by a variety of disciplines and may be looked at from the vantage point of the farmer or the consumer. Sustainable agriculture refers to agricultural production that can be maintained indefinitely while causing little to no harm to the environment, workers, and community.
- Understand that being certified organic doesn't guarantee sustainable practices. What an organic label means is that the food was grown or raised without the use of synthetic chemicals (but there ARE exceptions). Organic farming, especially when carried out on a large, industrial scale, can still damage the environment and threaten public health in a variety of ways: Ecosystems can still be ruined by widespread monoculture; pesticides can still be applied; soils can still be depleted of nutrients and organic matter; pollution can still be created; and exorbitant amounts of fossil fuels can still be spent (and wasted), all under an organic label.
- Become familiar with how sustainable agriculture is defined: Farming a single area so that it produces food indefinitely. In order to move in this direction, a farm has to avoid irreversible changes to the land (e.g. erosion), withdraw no resources from the environment that cannot be replenished (e.g. not using more water than can be replaced regularly by rainfall), and produce enough income to remain a farm in face of worldwide farm consolidation and infrastructure development.
- Consider the source. Where are your resources and inputs coming from? Think specifically about water, energy, soil amendments, and feed (if you have livestock). Also think about long-term, capital investments, such as structural building materials, tools, etc. Determine where your resources come from and whether you're taking more than can be replaced, either through natural processes or your own practices. Keep in mind that no farm is an island: complete self-sufficiency is not a requirement of sustainable agriculture. Long-term stability and productivity is. The more renewable and varied your resources are, the longer your farm will last.
- Eliminate waste. The three "R"s apply here more than ever: reduce, reuse, recycle. It'll not only be more sustainable, but it's cheaper, too. Examine every bit of garbage and waste that your operation produces and ask "What else can I do with this?" If you can't do anything to do with it, try to think of ways someone else in the community can use it. Be creative.
- Diversify ecologically. Choosing "polyculture" over "monoculture" results in less waste and often, reduced fossil fuel consumption.
- Encourage diversity within the farm.
- Use varieties and breeds that are well-adapted to the conditions in your locale, rather than bred for maximum productivity and storage (with a sacrifice in hardiness and flavor).
- Rotate crops and pasture. Use companion planting and green manures to keep the land perpetually fertile and to prevent topsoil loss. Don't let any one piece of land lose an irreplaceable amount of nutrients.
- Keep plants and animals around that indirectly benefit the farm's stability and productivity (e.g. plant extra basil to serve as an insecticide, keep guinea fowl around to keep ticks at bay).
- Raise both livestock and crops, and set up a mutually beneficial relationship between them. The simplest way to do this is to use manure from your livestock to fertilize crops, and use some of your crops to feed the livestock. If you are unable to raise both, find a neighbor who's specializing in the opposite and set up an exchange.
- Encourage the surrounding diversity.
- Plant trees around the farm that act as windbreaks and also provide habitat for local birds (which can prey on insects that prey on crops).
- Tolerate natural predators that keep pests at bay (e.g. snakes that feed on gophers, ladybugs that feed on aphids, spiders that feed on insects which spread diseases to crops)
- Encourage diversity within the farm.
- Diversify financially. An ecologically sustainable farming operation won't do anybody much good if it can't generate a profit and keep itself running. Unless you or someone else is willing and able to sponsor the farm with an off-farm day job or another external source of income, you're going to have to crunch the numbers until you're in the black.
- Take advantage of the options available to you as far as direct marketing is concerned. That includes: CSA/subscriptions, farmers markets, roadside stands, and even the Internet.
- Adding value to products is a smart way to differentiate this farm's lettuce from that farm's lettuce. When you take your lettuce and make it part of delicious burger made from healthy meat that was pasture-raised in your own fields and top it with a slice of tasty, red tomato that grew in your own soil, you stand to appeal to a wider audience and rake in more profits. In other words, don't just grow a wider variety of stuff--do a wider variety of things with the stuff you grow, and consider selling it from an on-farm store or restaurant (as well as the Internet).
- Cater to every economic level and ethnic group in the community. People of varying wealth seek different things from a farm. Certain ethnic groups value farm products that the mainstream community has no interest in (e.g. many Caribbean immigrants seek male, uncastrated goats for meat as well as amaranth, a widespread weed, which they use to make a dish called calalloo).
- Publicize. Talk to everyone about what you're doing at the farm. Provide educational tours and workshops. Keep your farm looking nice, because if it ever comes down to it, the local community may fight development proposals because they perceive your farm to be a haven of agricultural heritage.
- Find good, reliable labor. This is the most important and quite possibly your most difficult task. A reduced dependence on fossil fuels means an increased dependence on human labor, and not just physical, manual labor--you're going to need knowledgeable workers who understand the complexity of the system you're running and can enhance it with every decision they make. Find people who are committed to sustainable agriculture (not just dabbling in it) and who aren't afraid to get their hands dirty as they apply their minds.
- Enjoy your life. Farming is hard work, but the most successful farmers know when to call it a day and circumvent burn-out. Remember why you're farming and why, in particular, you're aiming for a sustainable operation. For most people, it's because they like knowing they're leaving land in better shape than they found it.
- Practicing sustainable agriculture information on a large scale calls for a very different approach than on a smaller scale. Tailor your sustainability practices accordingly. Don't try and produce 20 kinds of vegetables and raise 7 kinds of livestock over a plot of 30 acres unless you have the labor, knowledge and experience to manage it sustainably. Many farmers and ranchers who operate more than 50 acres mimic natural grazing systems that build soil and animal health through carefully thought-out rotational systems.
- The farmers who are most successful at applying the ideas discussed are those who can incrementally observe, experiment, observe, adapt, and repeat. It’s their farms that somehow overcome various challenges and, slowly but steadily, continue to grow in both complexity and stability.
- If you've found a great worker but you can't afford to pay them enough for them to make a living, be flexible and creative. Consider profit-sharing and/or equity building.
