Does Urban Agriculture Improve Food Security?

>

A newly published literature review in the Journal of Sustainability conducted by a team of Berkeley Food Institute researchers has found that while many studies cite the potential food security benefits of urban agriculture (UA), there are few that robustly measure the impact of urban farms on improving food security in low-income communities. Results of this review are guiding a three-year research project, funded by the Foundation for Food and Agriculture Research and the Berkeley Food Institute to investigate and address urban food access challenges in the eastern region of the San Francisco Bay Area, where interest in UA abounds, yet levels of gentrification, food insecurity, and income inequality are growing.

Without understanding the actual links between UA and food security or which specific characteristics, models or approaches reduce insecurity, urban policymakers and advocates risk backing policies that could have unintended consequences or negative impacts on vulnerable individuals and communities. We argue that in addition to more robust analyses that measure the actual social, economic, and health impacts of urban agriculture, and how they impact food security, it is important to understand which approaches to policy, governance and civic engagement support UA models that are effective in reducing food insecurity.

In general, we see three trends in current scholarship on UA in relation to community food security: (1) a focus on the production potential of urban lands, (2) individual case studies highlighting various nutritional, health, and other community benefits or outcomes from urban gardening initiatives, and (3) more critical analyses of UA through food justice and equity lenses. To this latter point, robust theoretical analyses have emerged critiquing the risks of UA when approached without an equity lens, potentially reinforcing structural injustices and racism and negatively impacting communities that ideally should benefit the most.

Deeper historical and structural challenges including poverty, racism, and divestment in specific communities and neighborhoods are increasingly being recognized as the root causes of the problem of unequal access to sufficient supplies of safe, nutritious, affordable, and culturally acceptable food facing cities. Designating land for agricultural use in urban areas may conflict with other city planning priorities around affordable housing, community economic development, or smart growth approaches associated with reducing urban sprawl and mitigating climate change, such as transit-oriented development. Because of the persistent legacy of systemic discrimination, it is neither inevitable nor guaranteed that urban agriculture will redress food system inequities; in fact, urban farms can sometimes lead to displacement through eco-gentrification. This is a particularly acute concern in areas experiencing housing pressures and population growth, such as the San Francisco Bay area and New York City.

Analyzing the intersection of food access and food distribution literatures reveals three key factors mediating the effect of UA on food security in the urban food system:

(1) the economic viability of urban farms (to sustain the provisioning of affordable urban produced foods)

(2) the role of city planning and policies in advancing racial equity through UA such as secure land tenure and public investment, and

(3) the importance of civic engagement to advocate for and hold cities and counties accountable to the needs of low-income communities.

We highlight examples from both the scholarly and gray literatures that demonstrate how UA can improve food access, distribution, and justice, in a way that supports both consumers and producers of food in cities. The gray literature in particular reveals many emerging and informal distribution networks for urban produced foods that would benefit from further academic study, such as gleaning networks, distribution apps, and online platforms.

The review concludes with a set of recommendations for researchers, practitioners, and policymakers who seek to create spaces in cities for food justice, equity, access, and sovereignty. Most notably we acknowledge that urban farms are producing a lot more than food; and that equitable planning, public investment and civic engagement are crucial elements in securing the long-term viability of urban farms. More robust analyses documenting the multifaceted benefits and risks of UA such as public health, food security, youth development, food literacy, eco-gentrification and environmental justice can help inform more equitable public policy and planning efforts.

Home is where the habitat is: This Earth Day, consider installing insectary plants

>

Help the environment this Earth Day, which falls on Sunday April 22 this year, by installing insectary plants! These plants attract natural enemies such as lady beetles, lacewings, and parasitic wasps. Natural enemies provide biological pest control and can reduce the need for insecticides. Visit the new UC IPM Insectary Plants webpage to learn how to use these plants to your advantage.

The buzz about insectary plants
Biological control, or the use of natural enemies to reduce pests, is an important component of integrated pest management. Fields and orchards may miss out on this control if they do not offer sufficient habitat for natural enemies to thrive. Insectary plants (or insectaries) can change that—they feed and shelter these important insects and make the environment more favorable to them. For instance, sweet alyssum planted near lettuce fields encourages syrphid flies to lay their eggs on crops. More syrphid eggs means more syrphid larvae eating aphids, and perhaps a reduced need for insecticides. Similarly, planting cover crops like buckwheat within vineyards can attract predatory insects, spiders, and parasitic wasps, ultimately keeping leafhoppers and thrips under control.

Flowering insectaries also provide food for bees and other pollinators. There are both greater numbers and more kinds of native bees in fields with an insectary consisting of a row of native shrubs planted along the field edge (called a hedgerow). Native bees also stay in fields with these shrubs longer than they do in fields without them. Therefore, not only do insectaries attract natural enemies, but they can also boost crop pollination and help keep bees healthy.

Insectary plants may attract more pests to your crops, but the benefit is greater than the risk
The possibility of creating more pest problems has been a concern when it comes to installing insectaries. Current research shows that mature hedgerows, in particular, bring more benefits than risks. Hedgerows attract far more natural enemies than insect pests. And despite the fact that birds, rabbits, and mice find refuge in hedgerows, the presence of hedgerows neither increases animal pest problems in the field, nor crop contamination by animal-vectored pathogens. Hedgerow insectaries both benefit wildlife and help to control pests.
 
How can I install insectary plants?
Visit the Insectary Plants webpage to learn how to establish and manage insectary plants, and determine which types of insectaries may suit your needs and situation. If you need financial assistance to establish insectaries on your farm, consider applying for Conservation Action Plan funds from the Environmental Quality Incentives Program (EQIP) offered by the Natural Resources Conservation Service.

August 19th is National Honey Bee Day: Dr. Elina NiƱo reminds us to help honey bees cope with pests

>

National Honey Bee Day is celebrated on the third Saturday of every August. This year it falls on Saturday the 19th. If you use integrated pest management, or IPM, you are probably aware that it can solve pest problems and reduce the use of pesticides that harm beneficial insects, including honey bees. But did you know that it is also used to manage pests that live inside honey bee colonies? In this timely podcast below, Dr. Elina Niño, UCCE apiculture extension specialist, discusses the most serious pests of honey bees, how beekeepers manage them to keep their colonies alive, and what you can do to help bees survive these challenges.

Urban Farming and Water Conservation: A Way of Life on the City Farm

>

Reyna Yagi (ryagi@ucanr.edu), Northern California Urban Agriculture Program Coordinator, University of California Cooperative Extension - Alameda and Contra Costa Counties

Raised Bed Irrigation - Treasure Island Job Corps Farm
It has been a banner year for water in California. The above-average precipitation and snowpack in 2017 have ended a five-year drought spell, leading Governor Jerry Brown to officially end the drought state of emergency last April for the majority of California counties. However, Californians know that this refreshing watery reprieve does not mean our conservation efforts stop here. With a draft plan in the making by the State Water Board appropriately dubbed “Making Water Conservation a California Way of Life,” the long term trend from this point on is efficient water use and drought preparedness, especially as we face climate change challenges.

How can we as urban farmers do our part to conserve water? Turns out there are a lot of ways that not only will help to save our beautiful state's water, but also help you build a healthier farm or garden with less work on your hands!

The Challenge of Water Access
It's hard to talk about water conservation when many urban farmers run into issues of reliable access to water and affordability of municipal water. Increasingly though, municipalities are working with urban farms and community gardens to offer discounts or grants for water meter and service line installation, help calculate a water budget, and provide a plethora of trainings and resources on efficient irrigation practices and technology. Talk with your local water municipality to see if they have discounted water pricing or special programs (San Francisco is a good example) aimed at assisting urban farms and community gardens.
 
Start with Healthy Soils
We know building healthy soils is key for the production and longevity of our crops, but it also allows plants to use water more efficiently and saves you water in the long run. Adding organic matter to your soil increases soil nutrition which helps plants produce better yields and bountiful blossoms without adding more water. Whether sandy or clayey soils, compost reduces the soil's need for water by 30% on average. Top it off with 3-4 inches of straw mulch to further your conservation efforts by keeping soil cool, preserving moisture and reducing weed germination.

Know What You Grow
Did you know it takes 33 gallons of water to produce a carrot while almonds require 1,280 gallons (find more facts here)? Follow seasonal crop patterns - cool season crops will take much more water in the heat of the summer. Once you decide what to grow, choose varieties that are labeled “drought-tolerant” or “widely adapted.” Be sure to group plants by similar plant watering requirements.

You Can't Manage What You Can't Measure
Do you know how much water your farm or garden uses? If you use a garden hose, you can estimate your flow rate by timing how long it takes to fill a five-gallon bucket. If it takes five minutes to fill, your flow rate is 1 gallon per minute. If you have an irrigation system and a water meter, it's easy to read your meter to find out your usage. There are also water gauges one can buy at your local hardware store as well. Keep a record; you may need it later.
 
Drip Irrigation is Your Best Friend
Drip irrigation is a worthwhile investment that not only reduces your workload, but conserves water by applying it where it is needed most and at a rate conducive to a plant's use. Another benefit for the farmer: it reduces weed growth, helps control mildew plus reduces fungus problems! Drip tape, soaker hoses, micro-sprinklers are among various types of efficient irrigation products you can use. Install shut-off valves to turn off areas that are fallow. Add an irrigation timer to automate your watering schedule. Controllers can also connect with rain and soil moisture sensors which shut the system off when enough water is applied.

Other Water Saving Techniques
  • Rainwater Harvesting allows you to capture rainwater from roofs, collect it in a cistern for diversion to your landscape for supplemental irrigation. You should also observe your site's water runoff patterns and see how you can manage and maximize your runoff to deal with large rain events, stormwater runoff and infiltration around your site. Consider a rain garden!

  • Dry Farming depends on the water stored in the soil from winter rains that plants can use in the spring as the weather warms. Plants rely on good soil moisture and deep roots to seek out this extra water without needing much supplemental irrigation. Grapes, potatoes, tomatoes, winter squash, fruit trees and grains can be dry-farmed.

And Remember:

  • Deep watering wets entire root zones which promotes deeper root growth.
  • Always water early in the morning to prevent daytime water loss through evaporation.
  • Keep an eye on the weather! A refreshing rain or cool, cloudy day will extend the time between watering.
  • Maintenance, maintenance, maintenance. Visually inspect your drip system regularly for breaks, leaks and missing pieces. If you don't, your plants will certainly let you know with plant diseases.

California's agricultural industry is the largest in the nation and abroad, carrying with that a great responsibility to protect and conserve our resources. Urban farmers are highly cognizant of this. They are some of the most innovative and conservation-minded folks out there who understand the fragility of our water supply and their role in being model stewards of our lands and waters.

Urban Farm Spotlight: GrowGood

>

In the most unlikely of spots, surrounded by warehouses, trains and light industry, GrowGood sits on a 1.5-acre site across the parking lot from the Salvation Army Bell Shelter. As you walk through the front gate, you find yourself amid hundreds of native plants and dozens of fruit and vegetable crops.

GrowGood is a Los Angeles-based non-profit urban farm with a mission to create urban agricultural programs that empower people and transform communities. Created in 2011 by Brad Pregerson and Andrew Hunt, GrowGood has worked with The Salvation Army's Bell Shelter to convert the vacant site adjacent to the shelter into an urban farm. The Bell Shelter is the largest homeless shelter west of Mississippi that provides a comprehensive transitional care program for up to 350 homeless men and women, many of them veterans.

GrowGood accomplishes its mission through three main strategies: (1) supplying a variety of nutritious, fresh produce to the Shelter's kitchen; (2) providing job training and meaningful resume-building employment opportunities for homeless and other vulnerable populations with the greatest barriers to employment; and (3) managing a therapeutic green space for spiritual and emotional healing.

Despite having been neglected for many years, GrowGood's soil biology has improved remarkably with time, patience, and beneficial cover crop seed mixes. GrowGood maintains organic practices without using chemical fertilizers, pesticides, or herbicides. The farm enriches its soil with compost and worm tea made on-site.

Most of what GrowGood produces goes to the shelter, including vegetables, herbs, and fruit, but you can also find their bounty in local Los Angeles restaurants.

Whether it's providing employment, providing nourishment, or hosting a community workshop – GrowGood has it all, and proves you don't need much space to “grow good.”
