In 1989, a large earthquake destroyed part of a San Francisco freeway that ran by the ocean.

The local community, however, managed to find a silver lining in the rubble — all thanks to a seemingly unassuming development: a farmers market.

Just a few years after the quake, they took what had once been a roadway in front of the historic Ferry Building and turned it into the Ferry Plaza Farmers Market.


Today, it's one of the top farmers markets in the country.

Aside from that, what makes the market particularly special is the organization that backs it — the Center for Urban Education about Sustainable Agriculture. They're all about cultivating a sustainable food system through community-based events, such as farmers markets and educational events.

And these local efforts are addressing a major, lesser-known challenge: food accessibility, particularly for those living in food deserts.

Farmers markets like the one at Ferry Plaza bolster communities by bringing together those who actually make and grow food and the people who buy it. That, in turn, helps us learn more about where our food comes from and what it takes to keep it coming.  

These markets also offer Market Match, which helps make fresh fruits and vegetables more affordable for low-income families by doubling their food stamp benefits at the farmers market. This may act as extra incentive for families living in food deserts to make the trip for healthier, locally sourced food.

But for CUESA, saving the planet starts with educating the next generation about sustainability.

"Education is at the heart of our work," writes communications director Brie Mazurek in an email. "We aim to inspire and empower people of all ages to become informed eaters and co-creators in a healthy food system."

They offer market-to-table demonstrations at their markets as well as farm tours where people can learn from the growers themselves and discover cool new recipes.

And if you're a kid, you can get even more involved with two awesome programs.

Students in the Schoolyard to Market program.

Foodwise Kids is a free experience for elementary students where they go on a field trip to a farmers market. They get to meet farmers, taste local foods, and prepare a meal together, picking up basic kitchen skills along the way.

Meanwhile, high schoolers have Schoolyard to Market — a semester-long garden and youth entrepreneurship program. They start a garden at their school, learning about the importance of sustainability and nutrition and how to run a successful food business. At the end of the semester, they actually sell their garden produce at a farmers market.

Kids leave the program with a much better understanding of how food systems work, and growing their own produce reminds them that fruits and vegetables can actually be delicious.

CUESA's certainly done their part for sustainable food systems over the last 25 years. Now it's time for every one of us to step up.

Some grocery retailers are already ahead of the curve. The Kroger Family of Companies, for example, makes it a priority to source locally, reducing their carbon footprint. They're also working on reducing waste with the Food Waste Reduction Alliance and helping improve the food supply chain, which has an overwhelmingly positive impact on the economy and environment.

And there are many ways that you can support the growth of this vital food movement, even if you don't own a grocery store or like digging in the dirt.

You can support local farmers and growers by doing your research and knowing where your food is coming from. Or you can go political and put pressure on your policymakers to support programs like the Supplemental Nutrition Assistance Program.

SNAP brings nutrition assistance to millions of low-income individuals and families. It also provides economic benefits to communities and works with educators and state agencies to make sure people are aware of the food benefits available to them.

If communities everywhere start supporting the sustainable food movement, our world's food future will look much brighter.

The next time you're planning a big dinner — or just a Tuesday night family dinner, for that matter — take a moment to consider where you're getting your food. Deciding to choose a place that supplies products from local farmers may not sound that heroic, but over time, it absolutely makes a difference.

Whether it's farmers markets or sustainability-conscious grocers that get your business, you'll be putting money toward better food for future generations and a better life for food producers today.

For as long as most people can remember, horizontal farming has been the only way to go.

But now, farmers are discovering that while horizontal fields of crops are beautiful, they might not be the best use of space.

As roots spread out across the ground, they leave a lot of unused real estate overhead. So what's stopping us from stacking our crops like densely-packed cities? Well, sunlight, for one. And gravity. Soil too.


But once that's all figured out? Perpendicular planting could be a much more efficient way to grow food.

What does vertical farming look like? Here are nine farms that are going above and beyond with their indoor produce systems:

1. VertiCrop

VertiCrop was the first big company to kick off the vertical urban farming trend, stacking shelves upon shelves of delicious greens that could produce up to 20 times the crop yield with only about 8% of the water of a comparable horizontal garden setup. Time magazine even named it as one of the world's greatest inventions in 2009.

Though the company had some financial trouble, they definitely set a high bar for the power of this kind of sustainable farming.

2. Growing Power Aquaponic System

This aquaponic system takes advantage of the existing symbiotic relationship between plants and animals.

The pump pulls water from a five-foot-deep pool to feed multiple layers of plants — in this case, watercress and tomatoes — then drips back down into the pool again, where the fresh oxygen helps to feed the tilapia in the tank below. It's like a little self-contained and portable ecosystem! (Also, the fish poo works as fertilizer.)

3. Wigan UTC Hydroponic Vertical Farm

This is believed to be the world's first educational vertical farm, where curious students can study, train, and experiment in farming progress.

At Wigan, a British university, the setup boasts a rotating soilless conveyor belt system, temperature and lighting controls, and even a state-of-the-art kitchen where students can actually start to develop recipes for the future (which may or may not include the delicious aquaponic fish they're raising as well — mmmm, space salmon).

4. DIY Windowfarms

These vertical windowfarms are catching on in major cities where everything is already stacked up tall and tight — 'cause hey, if it works for people in a city, why can't it work for plants? There are plenty of online communities offering tips, tricks, and instructions, but the basic idea is that you can set up rows of recyclable drip-water systems in the comfort of your own home. All you need is a window, some old plastic bottles, and string.

5. The Land at Epcot Center

That's right, even the mouse himself is getting in on the vertical farming action. And they're actually doing lots of cool research and experiments too! Plus, sometimes they make hydroponic mouse-shaped pumpkins.

6. Bright AgroTech Zip Farm

These innovators found a cool new way to make their vertical farming even more vertical. They're not just stacking horizontal flowerbeds upright: They use zip ties to create vertical planes that grow crops outward.

7. Green Sense Farms

Whoa, is that pink?!Green Sense Farms uses specially-made red and blue diodes to amplify the actual light rays that help plants grow. 'Cause who needs a full spectrum of colors when two of them can do the job even better?

8. Pasona Group Urban Farm

While vertical farms are great for making optimal use of space, what do you do in a place as densely-packed as Tokyo, where there's no room to build from the ground up? Simple: Start growing food in office buildings, like the folks at Kono Designs have done.

Not only does it produce some delicious crops, but employees are generally happier with the fresh oxygen in the air and the affective lighting. It's like being outdoors, but in an office!

9. AeroFarms

Last but not least, built inside a former laser tag arena just outside New York City, AeroFarms is known as the planet's largest indoor vertical farm to date, with the ability to grow 75 times more crops per square foot while using 95% less water.

Their system relies on an aeroponic mist instead of standard soil and uses concentrated LED lights, and — oh yeah — it's also being used to provide affordable food to underserved communities. Win.

Vertical farming doesn't just look cool — it's solving some serious planetary problems, and not a moment too soon.

This kind of urban agriculture is innovative and beautiful, which is great. But it's also a major step forward in addressing our impending food and population crises.

Between climate change and our rapidly increasing influx, some estimates suggest farmers will need to nearly double their crop output by 2050 if our civilization expects to survive — all while more than a quarter of our available farmland is already falling apart.

And while that sounds like a scary situation, these vertical farms are making sure we move upward and onward, so these kinds of problems can go right over our heads.
