Urban agriculture holds great promise for Boston.

This post was coauthored by Melissa Hoffer & Jo Anne Shatkin.

We are excited to share with you the news that today CLF and CLF Ventures released a report that, for the first time, details the economic development potential for urban agriculture in Greater Boston, assesses its environmental and health co-benefits, and examines current market and policy barriers to expanded food production in Greater Boston. The report‘s findings confirm that urban agriculture can play an important role in creating a more livable, carbon resilient, healthier, economically vibrant, and environmentally sustainable city—if we put smart policies in place and encourage market development for Boston grown foods.

The City of Boston has taken important steps over the past two years to advance urban agriculture, and new businesses are taking root, including City Growers, a Mattapan-based farming business that is featured in this report. There is a palpable sense of excitement about the potential of this new urban vision for agriculture for communities; possibilities abound. But CLF and CLF Ventures believe it is more than possible— it is a necessity, and an urgent one at that as we face the challenges of climate change, an obesity epidemic, lack of availability of healthy foods in many communities, and a fragile economy.

The report found that converting as few as 50 acres of vacant or underutilized land around Boston into agricultural production would spur job creation, improve access to healthy, local, fresh food, and reduce environmental harms. Key findings of the report include:

• Land is available. 50 acres – an area the size of Boston Common – is a small portion of the vacant or underutilized land available in Boston.
• Urban farms would stimulate the economy by creating jobs. 50 acres of urban agriculture in Boston will likely generate at least 130 direct farming jobs and may generate over 200 jobs depending on actual business characteristics and revenue.
• Healthy, local and affordable food. 50 acres in agricultural production would provide enough fresh produce to feed over 3,600 people over a six-month retail season. If the produce is used to prepare healthy school lunches in Boston Public Schools, 50 acres could provide more than one serving of fresh produce for each lunch served to a student eligible for free or reduced school lunch over a six month period. If 800 acres of potentially available City-owned land were put into agricultural production, the food needs of approximately 10 percent of Boston’s total population could be fully satisfied during a six-month retail season.
• Significant environmental impacts. Urban agriculture in Boston will result in a net reduction of greenhouse gas (GHG) emissions. 50 acres of properly managed soils would sequester about 114 tons of cabon dioxide (CO2) per year and may result in an additional CO2 reduction of up to 4,700 tons per year.
• Community adaptation. No less than 6,000 new temperature records were set during the recent March 2012 heat wave, and more than 40,000 have been set for the year-to-date. Meanwhile, the July 2011-June 2012 period was the warmest 12-month period of any 12-months on record for the contiguous U.S., with the first half of 2012 being the hottest ever recorded. The International Energy Agency’s recent projection of a 10.8 degree F temperature increase over pre-industrial levels by the end of this century underscores the fact that a more decentralized food system will be necessary to enable our communities to better adapt to changing climate conditions, including the impacts of more frequent severe weather. Urban agriculture is a part of this solution.

As Jo Anne said in the press release announcing Growing Green, it’s clear that even 50 acres of sustainable agriculture on available land would be an economic stimulus and environmental resource for Boston. While we focused on a 50 acre test scenario, these conclusions are scalable across New England. Imagine how vibrant New England would be like with a robust and sustainable regional food system.

In addition to the potential benefits, the report also considers the policy and market barriers to fully realizing the potential of urban agriculture, examining the ways in which promoting urban agriculture will require city and state involvement and key needs for such involvement. Such barriers include the need for policies that provide affordable access to land, one of the key market barriers for both new and experienced farmers; strategies to reduce the risks associated with the Commonwealth’s hazardous material cleanup law; improved access to high quality compost; and better financing options to overcoming prohibitive capital and operating costs, amongst other findings.

Our ongoing work seeks to link urban agriculture to the larger regional food system, and focuses on how to overcome some of the barriers we have identified.

Boston is ideally positioned to play a lead role in coordinating with the Massachusetts Food Policy Council, other New England states, and cities around the region to build a vision for a New England regional food system and make it happen. Boston is emerging as a national leader in urban agriculture innovation, and can be a voice for the benefits of urban agriculture and as one of the region’s largest consumers, help to build the market for regionally grown food.

An urban garden -- precisely what we need more of. Photo courtesy of Tony Fischer Photography @ flickr.

It began with our tomatoes. As I’ve written before, my wife and I are avid gardeners and have grown tomatoes many times before but these – these tomatoes were proving difficult to grow. This was not due to the plants, but due to me and to the setting in which we were growing them: the rooftop of our apartment building in the city of Somerville, MA.

My wife and I had decided to grow tomatoes in containers on our roof for the same reasons many do: we wanted to continue our hobby after moving to the city, and we wanted fresh vegetables we had grown our selves. Much like catching a trout on a fly you yourself have tied, there is something immensely gratifying about this sort of self-reliance. The tomatoes just taste better.

But they did prove difficult. Growing tomatoes in plastic buckets on a black roof under the summer sun requires mastering the art of properly irrigating your plants. First we watered them too much. Then we watered them too little. I remember at one point standing over my plants, wondering at what I had done wrong, and looking enviously at the elaborate, automatic watering system my engineering neighbor had constructed and perfected for her tomatoes. Finally, we got it right.

Adapting to growing a garden on an urban roof, not a field in Vermont, proved to be a challenge. And I learned some lessons that help me to understand some of CLF’s work better.

We need to grow food in areas we don’t think of as farmland. As I hear more about urban agriculture growing in our cities, the more I am convinced that our cities are fertile ground for growing food. Cities are not only sites of consumption, but also of production, and are essential to a strong regional food system. Just as we support traditional New England farms, so too should we support community gardens, rooftop gardens, porch and patios plantings, and other urban horticulture. To eat in the city, we need to grow in the city.

As I look around, I see plenty of evidence that we’re on the way to making this happen.

Many of the staff at CLF are growing their own food: a few have plots in community gardens, one works for a CSA in Concord, MA, many have gardens, one raises goats, another a slew of barn animals, while plenty others have small porch or window plantings at their apartments and homes.

I know we’re not alone, either. Young people are turning to farming not just as avocation but as vocation. They’re tilling rural soil, certainly, but also planting new beds amongst our city streets. It’s a new generation, in more ways than one.

I also see more CSAs now than I ever noticed before. My wife and I have been members of several CSAs for a number of years, in Burlington, VT, and Boston, MA. Now, I see more access, in more areas, to the kinds of food provided by these CSAs than ever before.

We participate in food systems whether we choose to or not, by virtue of the fact that we all eat. And, as the old saying goes, you are what you eat. Phrased slightly differently, food is at the heart of many of our problems: our thirst for fossil fuels, our polluting farm infrastructure, economic inequity and the obesity epidemic. If we fix our food problem, we make it easier to fix some of these other problems as well.

In the current issue of Conservation Matters, there is an article about how CLF and CLF Ventures are working to improve our regional food system. As I said in my president’s letter, “sustainable agriculture, when applied to cities, makes them more resilient, economically vibrant and livable.”

Standing on my rooftop, viewing my tomatoes, this struck me as true: we need to grow more food in areas we don’t think of as farmland. We will be more vibrant as a region, stronger as communities, and healthier as individuals.

A couple of weeks ago I met a young farmer near Rutland, VT who was stunned to be out plowing his fields in the month of March. At that time the fields are usually knee-deep muddy, if not still covered in snow, ice or the slow-melting crust of the long winter. He was stunned:  if he plows and plants now, what’s going to happen next? How will his crops respond? Should he wait, for something more like a “normal” planting season to return?

These are questions that thousands of us gardeners across New England have been struggling with lately, in the wake of an unseasonably warm spell, and a winter that broke records first for early snowfall, and then low overall snowfall and high temperatures. Looking out our windows when the weather warms, we are drawn to one place: the soil – we long to get our hands in the dirt, and smell the wonderful scents of spring. For the farmer I mentioned above, the decision wasn’t just recreational or therapeutic; the crops for the CSA he recently founded with his partner were at risk. He had to plan carefully, not knowing what lies ahead.

In Vermont, where my wife and I have tended our garden for years, you start your seeds on Town Meeting Day and plant on Memorial Day. But this year, that timeline is way off.

Recently, for the first time in 22 years, the U.S. Department of Agriculture released an updated version of its Plant Hardiness Zone Map. The map charts average winter minimum temperatures, or cold intensity. What this map confirmed in VT is what we have observed anecdotally across New England and the United States: that our world is warming, as this map by the Arbor Day Foundation shows vividly. For the first time in VT, for instance, zone 5b has crept into the southern edges of our state. And the south coast of Connecticut, Rhode Island and Massachusetts includes zone 7a, which is also found in Northern Alabama. The commentary on the new map carefully avoids concluding the shifts are the results of climate change; most gardeners will draw their own conclusions.

For me, the question of whether or not to plant returned me to a question about my greenhouse. Previous owners of our house built a small, traditional greenhouse that helped with the slow and wet transition from winter to spring, with consistency and in the same place for 15 years. It succumbed to the elements recently, and we decided to try smaller, portable hoop houses over our raised beds. They’re more suitable to highly variable temperatures. Where once a rigid structure suited our weather and our needs, that’s no longer the case. We need to be more flexible. More adaptable.

This winter ranks as the 4th warmest nationally since the late 1880s, when climatologists began keeping records. People still consider Memorial Day as a safe time to plant, but the average last frost day is 10 days prior, as Vern Grubinger, University of Vermont Extension vegetable and berry specialist, said in this Brattelboro Reformer article.

What happens when you plan according to tradition, but the seasonal calendar is out of kilter? What happens when convention no longer suits our contemporary reality? These are questions of adaptation, and they apply to backyard gardens – and also flood zone mapping, transportation, and almost everything we do in the natural world. We have to start building differently, for a different world.

And so I wanted to ask you – CLF members, and members of the public alike – how are you adapting? What have you done with your garden this spring?  Are you anticipating odd weather in the months ahead? How will you respond? Please share your comments here and share your photos with us on our Facebook page.

I look forward to hearing from you. And happy planting.
