Food Economics: Where in the World… and Why?

Food EconomicsThe harvest stage of a school garden provides an ideal setting to observe interdependence of producers and consumers: harvesting food in the garden vs. buying produce in a store or a restaurant.  This is when Social Studies benchmarks can be supported in the garden and students can gain an understanding of how consumer choices affect food sustainability on Maui.

Discussion Points

Limited Resources and Choice: Explain scarcity and effects on daily life. Discuss water scarcity in Hawaii and how it affects farmers / gardeners. What happens when there is less rainfall on the island? How does it affect farmers? What happens if local farmers stop producing a fruit or vegetable? How does it affect the price? What happens when consumers buy imported produce instead of local produce? How does it affect a local farmer’s ability to grow more?

Role of Government: Discuss responsibility of government to provide goods and services – ie. In supplying water to areas where needed.

Economic Interdependence / Role and Function of Markets:  How do people benefit from trade (exchange of goods and services)? Discuss relationships between buyers (consumers) and sellers (producers) and how they depend upon each other. Why do farmers need customers? Why do customers need farmers?

ActivitiesFood Economics

  • Display imported produce: a tomato (from California), banana (from Ecuador), eggplant (from Philippines), cabbage (from Mexico) and ask the students to find where these items are growing in the garden. Have students search for “local” produce bring a sample of each back to circle (or a leaf from the plant if fruit or vegetable is not ready to harvest).
  • Locate origin of each imported produce item on the globe and estimate how many miles / amount of time each one traveled before being sold to the consumer here on Hawaii.
  • Discuss all the human resources involved in delivering that food (farmers, truckers, shippers, store clerks, etc.). Which ones require gas/fuel to do their jobs? Students act out each stage of delivery and exchange.
  • Compare the imported food chain to how many steps / people / how much energy or fuel it took to deliver food from the garden to the table.
  • Ask students if they know someone who grows food on Maui. Discuss the concept of local vs. imported. What is local? Are you local? Why?
  1. If you bought a local banana from a store that sells your uncle’s / auntie’s bananas, who would get the money?
  2. If you bought an imported banana from Ecuador, who would get the money?
  3. If a local farmer gets money for their bananas, can they grow more local bananas? Why?
  4. How can you tell where something comes from when shopping in a store? Show examples of food labels that list the origin of produce.

Final Observations / Questions
Why do stores in your neighborhood import food from other countries? Not enough supply? Not enough demand? Do imported bananas taste better?

  • Taste testing: Sample and compare slices of a banana from Ecuador or other country to an apple banana from Maui. Samples are divided on two plates with no identification on origin.
  1. Which tastes better? Then, reveal which bananas are imported vs. local.
  2. How does supply and demand affect a store owner’s decision to carry local vs. imported bananas?
  3. Which consumer choice supports farmers who live on Maui?
  4. Which banana would you choose? Why?

World Class Chefs + 1,000 Students Celebrate School Garden Harvest Fest

kihei elementary school students prepare stir fry ingredients with garden grown veggies For three full days, April 24-26, world-class chefs led garden recipe workshops with more than 950 students in nearly a quarter-acre of garden space in the heart of the Kihei Elementary School campus. Kindergarten through 5th grade students and chefs prepared Asian stir-fry and gourmet veggie pizzas using ingredients grown and harvested from the school’s Pizza Garden and Gardens of the World. Students chopped, peeled and spiced their garden delights before chefs tossed them into a giant wok and wood-fired pizza oven and served it up in a pop-up café to celebrate the school’s annual Harvest Fest.

Soil Building with Cover Crops

The hottest summer months in Kihei are tough on most garden plants, but it’s a great time to introduce cover crops for improving soil health and preparing for the next planting season. These crops also serve as great tools to teach students about nitrogen and its role in the life cycle.

All plants need nitrogen to make amino acids, proteins and DNA. Approximately 80 percent of the air surrounding the earth is nitrogen gas. However, nitrogen in gas form is not usable by most plants. First, nitrogen needs to be converted from its atmospheric gas form to ammonium compounds to become available to plants. To achieve this, many organic farmers use nitrogen-fixing cover crops. Cover crop benefits and tips include:

Boosting Soil Fertility & Nitrogen Fixing

Cover crops, also known as green manures, recycle nutrients and add organic matter to the soil.  The nutrients are absorbed and stored inside plants. When nutrients are needed for the next crop, the old plants are dug into the soil or used as mulch on top of the soil. We always explain to students, “old plants make food for new plants.”

Legumes – such as alfalfa, peas, beans, clover and vetch – are particularly beneficial to replenish nitrogen available to plants. During the process, called “nitrogen fixing,” rhizobial bacteria take residence in root nodules of legumes and convert biologically unavailable atmospheric nitrogen gas to a plant-available ammonium compound.

Inoculating Seeds for Better Nitrogen Fixing

There are multiple strains of nitrogen-fixing rhizobia, and each is specific to a certain type of legume. For instance, the rhizobia strain associated with vetch will also work with peas, but not alfalfa. When legumes are inoculated with the proper strain of rhizobial bacteria, they produce large, pink nodules on the roots of the host plant. The pinkish color indicates the presence of a hemoglobin-like molecule that is necessary for nitrogen fixation to occur.

Rhizobia live naturally in the soil. However, the strains already present may not always be compatible for your cover crop or in the amount necessary for effective nitrogen fixation. To increase the odds, many gardeners inoculate their cover crop seeds by lightly dusting them with the appropriate rhizobial bacteria strains prior to planting. Rhizobial bacteria powder may be found in or near the seed section at your local nursery. Check the label to ensure the inoculant matches your cover crop seed of choice. We’ve had difficulty finding inoculant on store shelves on Maui, so ordering online is the best option here. Peaceful Valley has a great selection of seed inoculants with instructions on proper use of each strain.

Improving Soil Structure & Habitat

Cover crops strengthen soil structure, letting more air into the soil, improving drainage, maintaining viable living space for beneficial microorganisms and insects. Cover crops can also help the sandy soils found in Kihei hold more water. While some cover crops are drought resistant, beneficial bacteria generally fare better with moisture.

Preventing Soil Erosion and Compaction

Cover crops help prevent soil from being carried away by wind and rain. The roots penetrate the soil and hold it in place. Having plants constantly growing in your gardening spaces also gives a visual cue to help deter kids from marching through and compacting the soil.

Controlling Weeds

Bare soil can become quickly overgrown with weeds, which can be difficult to remove once they’ve become established. A good ground cover can prevent weeds from growing by competing for nutrients, space and light.

What and When To Plant in South Maui

Here are a few pieces that we’ve gotten from various sources that may help others decide what to plant and when to plant it.

This one page summary tells what to plant by elevation.  (Source: Master Gardeners)

Vegetables in South Maui Chart  – This list was prepared and presented by Susan Wyche at a South Maui Sustainability session on growing in South Maui.

A few tips for beginners:

  • One of the easiest things to grow here is basil.  It works year round, sun or shade, in a container or in the ground.  Pinch off flowers to keep sweet flavor. Plant different types for culinary delight.  Take cuttings if plant starts looking tired, put them in water and plant the “new plant with roots” in about a week.
  • Cherry tomatoes are the easiest to grow here.
  • One issue during the summer is transpiration.  With our hot winds and sandy soil a plant may wilt in just hours. With watering they may actually perk up but if you see this happening, you may have to water twice a day!  Mulching helps as does adding more compost to the soil.
  • When plants “go to seed” before they are even ripe or full grown, it is often because our soil temperatures are high.  Spread mulch thick and recognize that some things just won’t grow during our hot seasons.

Garden Tip: Treating Slugs with Coffee

Garden Tip: Treating Slugs with Coffee
For an all natural, good for your soil and plants slug treatment, use your leftover morning coffee and coffee grounds around your vegetable garden plants. While different studies have shown varying degrees of success using coffee sprays and coffee grounds to treat for slugs, we’ve had great success using coffee in the Kihei Elementary School Garden project. It really works. Read more about the University of Hawaii study on treating slugs with caffeine.

Powdery Mildew and Other Fungal Diseases

Not many gardeners have gone a season without some powdery mildew. Even in dry areas, a sprinkler gone awry can cause this fungus to seemingly creep over a garden and destroy it in days. We got this tip for keeping powdery mildew under control from the keynote speaker Tane Datta at CTAHR’s  Organic Gardening Workshop.

Remember that powdery mildew is a fungus that usually appears as a white or gray powder on tops of leaves. The first sign is usually twisting and curling of young leaves on the lower part of the plant. You usually see it on beans, cucumbers, melons, mangos and squash but we’ve seen it on tomatoes and many ornamentals too. Although it rarely kills a plant, it causes poor growth and lower yields.

Prevention is the easiest way to manage any fungi by ensuring plants are healthy, get enough sunlight and have good air circulation. If you have had problems before, choose mildew resistant varieties. Make sure not to overfeed your plants as this severely stresses them.

Fungi spreads from the spores being flown around by wind or from just growing from one plant to another. Spores can live in the soil for a long time.

Always make sure to sanitize (remove) really bad areas. Be careful to not shake the foliage as that will spread the spores. It is ok to put plants with powdery mildew in your compost pile as long as the pile gets hot. Otherwise, discard in a sealed plastic bag.

So here’s the big tip — don’t try to treat Powdery Mildew the same way each time. Mix up different types of treatments and you’ll have a lot more success! Here are a few of the organic methods people report having success with.

  • Spray liquid seaweed onto your plant’s leaves. Research has shown that this has a powerful “booster” effect to your plant’s health and it helps fight off the powdery mildew.
  • Sulphur sprays are quite effective at stopping the spread of powdery mildew. They also destroy beneficial soil fungi as well so don’t spray too much.
  • Mix 1 heaping tablespoon of baking soda, 1 tablespoon of dormant oil, and ½ teaspoon of insecticidal or dish soap in one gallon of water.
  • Mix cow’s milk at a ratio of one part of milk to nine parts of water and spray weekly.
  • Pour one part of standard 3 percent-strength hydrogen peroxide with three parts water. Spray on plants daily until mildew subsides.
  • Kaligreen® is an organic solution with potassium Bicarbonate. Mix according to instructions.
  • SERENADE® is another organic product that comes in both a powder and liquid.
  • There are also fungicidal products on the garden center shelves featuring jojoba oil and neem oil.
  • Here a new one… one of the most effective measures in preventing and treating powdery mildew is to spray the foliage of your plants daily with plain water from the hose. Powdery mildew hates water! The only caveat with this method is to be sure you do it early in the day so that the foliage completely dries before cooler evening temperatures arrive, otherwise you may invite other fungal diseases, such as black spot, into your garden.

Today we explored the 5 Senses in the Garden with Kihei Elementary School kindergarteners and turned nitrogen-fixing and phosphorous-rich cover crops into the soil for a final round with all grades before planting new fruits and vegetables for the year.

To start the adventures, Chef Kristin Etheredge gave each student gardener a taste of fresh apple bananas from her home and juicy strawberry papayas, then collected compost scraps to feed the soil. As we sampled the harvest, students talked with Kathy and Kris about similarities between soil health and human health, plant parts, decomposers in the compost, then discovered a bright red ladybug on a tour with Gadener Kirk, learned about beneficial insects and brainstormed describing words to write in their journals.

Mahalo to all for sharing mana’o and helping to inspire a new generation of chefs, teachers, scientists, farmers and urban gardeners on these islands!

Why Care About Pollinators?

Pollination — the transfer of pollen grains to fertilize the seed-producing ovaries of flowers — is an essential part of a healthy ecosystem.  And pollinators play a significant role in the production of over 150 food crops in the United States.In this introductory curriculum educators have purposely chosen to focus on just two of the many pollinators as a means for teaching basic concepts about the process and importance of pollination.

Bees were chosen due to their primary importance among pollinators and butterflies were chosen because of the interesting and distinctive stages of their life cycle and their intrinsic appeal.

Find out more about butterflies, bees and other pollinators through activities designed to provide a systematic exploration of the topic using  scientific thinking processes at the Pollinator Partnership’s website.  This SERIES curriculum was funded through a grant from the United States Department of Agriculture.

The Nature’s Partners curriculum contained here is designed to be a highly adaptive and flexible resource for teachers and youth leaders.   Here’s a link to one of the learning modules if you’re ready to buzz and flutter into the world of pollinators.
