In April, I attended the Growing School Gardens Summit in Denver, Colorado, thanks to support from UCCE San Bernardino. The conference was promoted as “a gathering to inform, inspire, and invigorate the school garden movement” and was hosted by the Sprouts Healthy Communities Foundation in partnership with LifeLab and the School Garden Support Organization (SGSO) Network. It was so exciting to meet school garden educators and influencers from across the country and return home with a suitcase full of seeds, handouts, business cards, and healthy snacks to motivate me for months to come! In this blog, I want to share my most memorable moments from the conference and give you an update on the Upland High School waste audit.
Growing Garden Leaders
Monthly webinar topics included planting with students, culinary connections, garden maintenance, seed saving, and composting. To keep trainees engaged remotely, a variety of tools and techniques were used: guest speakers, school and teacher spotlights, live demonstrations, breakout rooms, interactive group platforms, activity kits, Q&A sessions, and a social media group. I'm always looking for more tools to add to my environmental education toolbox! In addition, this type of “train the trainer” framework could be useful for our Master Gardener School Garden Committee.
Providing Effective Support to School Gardens
The “Growing Garden Leaders” workshop dovetailed nicely with another workshop held on the last day of the conference. “Providing Effective Support to School Gardens in Your Region” showed how to increase the impact and effectiveness of garden-based activities with limited capacity. Presented by the United States Botanic Garden and the Office of the State Superintendent of Education (both in Washington, D.C.), the session introduced the Multi-Tiered System of Supports (MTSS) framework. This approach advocates building a strong foundation of “tier 1” activities that are available to everyone and disseminated widely. About 80 percent of those served will get what they need from tier 1. Two examples are a school garden guide and a monthly newsletter. The remaining 20 percent will need more support from tiers 2 and 3 such as group training or a site evaluation. This concept resonated with me because our School Garden Committee just finished adding school garden resources to the Master Gardener website, a tier 1 activity. Now we have a place to refer those who contact us for help.

Edible Schoolyard New Orleans
Staff from Edible Schoolyard New Orleans gave two excellent short talks. Sasha Solano-McDaniel discussed how a Spanish cooking club enabled language acquisition in the kitchen classroom. Both English language learners and native English speakers benefitted from sharing their cultures and building community. Brian Tome outlined how he created a resilient, undemanding, and educational garden at the Phillis Wheatley Community School. He accomplished this by planting cover crops and perennials and creating a food forest using plants common in the tropics and subtropics such as taro, ginger, turmeric, papaya, and lemongrass.
Food Forests for Schools
My favorite presentation of the conference was “Food Forests for Schools” presented by The Education Fund, a non-profit organization that provides leadership and support for public education in Miami-Dade County, Florida. Food forests are multi-layered food growing systems consisting of trees, bushes, herbs, vines, and ground covers. In Miami-Dade County, 26 of the 51 elementary schools have perennial, edible landscapes that provide food for students to take home and eat in the cafeteria.
Through the Edible Outdoor Eco-Labs to Accelerate Learning program, The Education Fund installs food forests and shows schools how to use them as outdoor classrooms to teach science and nutrition lessons. The main design elements of the food forest are a defined entrance, walking paths, an outdoor classroom, and a compost circle surrounded by banana trees. I would love to see this type of design used in more school gardens in Southern California. Many tropical plants that grow in South Florida can also grow here at lower elevations.
Building a Sustainable School Garden Program
In “Building and Institutionalizing a Sustainable School Program”, Dan Brown, a junior/senior high school teacher in rural Northern California, described how he and his students started with an existing greenhouse to build a garden program that now sells about 2000 pounds of organic produce each year. In 2007, he began applying for grants and used the Ag Mechanics shop to build raised beds, cold frames, shade frames, and high tunnels. Over the years, the garden program has sold many types of plants and produce, saved seeds, and run a CSA (Community Supported Agriculture) project.
Green Bronx Machine
Green Bronx Machine started as an after-school, alternative program for high school students and has evolved into an organization that serves more than 50,000 students with an interdisciplinary, project-based curriculum. Green Bronx Machine also supports the Food for Others Garden on a decommissioned city street in the Bronx, a wheelchair-accessible urban farm and culinary training kitchen for special needs students, and an outdoor Learning Garden at Community School 55 among many other projects and partnerships. Truly amazing!
Upland High School Waste Audit Update
As a follow-up to the waste audit, the UUSD Nutrition Services Department is evaluating ways to collect and recycle food waste, increase education on school meal requirements, provide share buckets for unwanted items, switch to bulk condiments and sauces, and make more sustainable purchasing choices. Changes such as these will help UUSD meet the Senate Bill 1383 requirements for organic waste reduction and edible food recovery.

Ever since Senate Bill 1383 took effect earlier this year, local governments and organizations across California have been scrambling to develop strategies to recycle organic waste. Schools are no exception. As I discussed in my February blog, SB 1383 requires our state to reduce organic waste disposal by 75% and increase edible food recovery by 20% by 2025 (relative to 2014 levels). California schools and universities generate over 560,000 tons of waste per year according to CalRecycle.[1] While implementing programs to reduce and recycle waste, schools are in a unique position to teach youth about a wide variety of environmental topics including resource conservation, composting, and food rescue.
A good way for schools to start developing a waste handling strategy is to conduct a waste audit. The main goal is to characterize the type, quantity, and source of materials being discarded. An audit is often part of a more comprehensive assessment to evaluate school district policies and procedures that affect waste generation. In 2014, CalRecycle performed a waste characterization study using 45 samples from K-12 schools.[2] The study showed that the largest components of the waste stream were organics (50.8%), paper (31.4%), and plastic (12.7%). The organics category included food, plant material, and some textiles.
I recently helped Cassidy Furnari, the Upland School District Farm to School Program Manager, conduct a lunchtime cafeteria waste audit at Upland High School. The Farm to School Program is part of the Nutrition Services Department, which is concerned about food waste and cost. Cassidy and I recruited members of the school garden club, GRO (Grow Recycle Organize), to participate in the audit to empower them to promote change on campus. The students are currently preparing to present their results at an upcoming Board of Education meeting.
The first step we took in planning our waste audit was to write a brief project plan. To keep the project manageable, we decided to perform an audit during a typical 30-minute lunch period. Upland High School has over 3000 students who all eat at the same time. Only seniors are allowed to leave campus during lunch.
To avoid influencing student behavior, we didn't make any major changes to the meal service or trash disposal. Rather than asking students to sort their own waste, we placed distinctive purple liners inside existing trash containers shortly before the lunch period. The week before the audit we counted over 90 trash containers in the areas where students eat lunch.
During the planning process, we informed and consulted with the school administration, cafeteria staff, custodial staff, and parents of the garden club members. We also asked for help from our friends at the Community Composting for Green Spaces Grant Program to tap into their experience with waste audits.
To design our data collection sheets, we considered what questions we wanted to answer. What is the total weight of the waste? How much of the waste is food, paper, plastic, aluminum, and glass? How much can be composted or recycled? How much uneaten cafeteria food can be recovered? By answering these questions and others, we can help the Nutrition Services Department make more sustainable and economical food purchasing and packaging decisions.
After a month of planning, the big day of the waste audit finally arrived on March 9th. Our team consisted of nine people from Upland Farm to School and Community Composting for Green Spaces. Our first tasks were placing purple bags in the trash receptacles and setting up a staging area to sort the waste. Before we knew it, the lunch period had come and gone, and the hard work of collecting the bags and sorting the waste began. Sorting was much messier and more tedious than I had expected, especially since we had over 30 waste categories. The garden club members joined us after school to help count, weigh, and record the items in different waste categories. We eventually finished tallying the results and cleaning up six hours after we started. It was a long day!
What did we learn from our waste audit? Although we're still analyzing the results, we've already answered our initial questions. The total waste generated in a single lunch period was 370 lbs. The two largest types of waste material by weight were food (63%) and paper (19%), and more than 80% of the waste was compostable or recyclable. Students threw away over 200 pieces of uneaten whole fruit and 40 unopened cartons of milk, which potentially could have been recovered. Every question we answer gives rise to new questions and new ways to examine the data. We're already thinking about performing a waste audit at an elementary school to see how the waste profile compares.
I hope this story inspires you to support waste reduction, recycling, and recovery efforts in your local schools. Stay tuned for an update on my journey into school waste auditing in a future blog!
