The final assignment for a recently piloted "Climate Resilience Course for Farmers" from the MESA organization is for all participants to create a Climate Resilience plan for their farm. This is a proactive approach to minimizing effects of climate change (rather than just reacting to effects), and one option for students to undertake as a final assignment for the schoolyard or school garden. For examples of climate resilience plans, contact the MESA course organizers via their website.
Check out the University of California’s “Bending the Curve” report for a 10-step outline for mitigating climate change; could be shared with students to provoke ideas for school climate action projects.
Do Now: As a class, complete the carbon footprint calculator for the teacher on“CoolClimate Calculator” and write down 3 ways you could reduce your carbon footprint. At least 1 should focus on food consumption/production.
*Requires basic sense of electric bill/monthly utility consumption; teacher should bring in bill if possible
What are three ways an individual can reduce their contribution to climate change (by reducing carbon emissions)?

What percentage of your carbon footprint relates to food?
Mini Lesson: Explain the difference between adaptation (adjusting to the changes that are happening/going to happen) vs. mitigation (making efforts to reverse or decrease impacts of climate change). Mitigation can happen at many levels, from individual to international. And, we're all going to have to adapt!
Optional activity: Pacala and Socolow Stabilization Wedges game (see supplementary materials).
Activity 1: Solutions circle- post examples and explanations of climate change mitigation activities around the room (soil carbon sequestration/carbon farming, agroecology, permaculture, intercropping, composting, crop diversity, urban agriculture/rooftop gardens) and have students do a gallery walk.
Famous farms who are leading the charge here: Shelburne Farms (VT), TomKat Ranch in CA, Marin Carbon Project Farms (CA), Midnight’s Farm on Lopez Island, Peter Donovan’s Soil Carbon Coalition farm participants… many others

Carbon Farming resources, videos, podcasts (for teacher prep or sharing with students).
Activity 2: Compost activity! [Option: Discuss/prep for garden work next day] Go over compost’s specific role in enhancing soil carbon sequestration (see Marin Carbon Project website), then go out into the garden and apply some compost, rehabilitate the compost bin, etc. Talk about carbon sequestration while composting; feel the difference between carbon-rich and carbon-poor soil
Extension 1: Add a thermometer to compost pile to measure temp, or apply compost somewhere it has never been applied before to start a “field trial” of effects of composting. Measure the temperature daily for a week, and chart the temperature changes on a graph.
Extension 2: Start soil monitoring project: Collect soil sample from garden, once composted, to send in for soil testing analysis. Doing this annually can allow your school garden to measure change in soil carbon over time, hopefully demonstrating net carbon increase. Soil test kits are available for purchase at local nurseries, and from lab-certified test kits such as this (if funding is available).
Close: Brainstorm in groups of 2-3 about the best solution that could be implemented here to mitigate climate change. Solution can incorporate school garden, cafeteria, classroom, and surrounding community. (Bonus: include in your brainstorm solutions that also adapt to climate change, noting the difference between adaptation and mitigation).
Optional discussion prompt: What other benefits do you notice about climate-related solutions that farms can adopt? Are the benefits of these activities limited to reducing climate impacts, or are there benefits in other areas?
