Eco Kids Column: Laundry Scoop Wheelbarrows


(Idea and image from StorkNet Kids' Crafts)

What can do you with all the laundry scoops that come with each new box of laundry detergent? Here is a simple craft idea that repurposes laundry scoops into seed starter kits that you could give out as gifts or party favours.

1. Laundry scoops
2. Acrylic paints, permanent markers or stickers.
3. Buttons or round wooden or metal discs. (Two for each laundry scoop)
4. Glue
5. Potting soil
6. Tiny plants, e.g. ferns, or seeds.
 8. A corkscrew for drilling a hole with.

1. Drill a hole at the bottom of your laundry scoop to allow excess water to drain out. You may need an adult's help for this.
2. Decorate your laundry scoops with paint or markers to make them resemble wheelbarrows. A gardening or floral theme would work well with this craft idea.
3. Decorate the buttons or discs with a black marker or paints to make them look like wheels.
4. Wait for the paint or ink to dry. Then, glue the "wheels" of your wheelbarrow in place. Let the glue dry.
5. Fill three-quarters of the laundry scoop up with potting soil.
6. If you are using seeds, push a few seeds gently into the soil. Mung bean (or green bean) seeds will work for this project. Space the seeds out so that they have room to grow.
7. If you are using live plants, make a shallow indentation in the soil with your fingers and gently put the plant into the soil. Cover the soil around the roots of the plant but do not pack the soil in too tightly.
8. Sprinkle water onto your plant or seeds. Ensure that the soil is damp but not wet or flooded. If the roots are waterlogged, the plant may die. Try making several wheelbarrows and putting them in different parts of your home to see under what conditions will the plants thrive. Does your plant like direct sunlight? Or does it prefer the damp coolness of the bathroom window?

The Challenges Ahead: Safe & Sustainable Vegetable Farming

Once every few years, the media will report of rampant land clearing, water pollution, use of banned pesticides and environmental degradation in the Cameron Highlands as a result of intensive agricultural activity (Cameron Highlands in terrible shape due to land clearing and water pollution, The Star, Dec 11 2012).

This draws attention to the challenges of reconciling food security with environmental integrity. In their research paper published in 2009, Drs. CJ Barrow, Chan Ngai Weng and Tarmiji Masron had pointed out that the expansion and intensification of farming in the Cameron Highlands had seriously polluted streams and groundwater with sediment, manure-enriched runoff, agrichemicals and sewage. The same report found that large numbers of vegetable growers were reported to be using banned pesticides imported from Thailand and other countries, as illegal agrichemicals are seen by the farmers to be cheaper and more effective. In addition, the preference for uncomposted chicken manure over chemical fertilisers by the vegetable farmers of Cameron Highlands has resulted in an increase of pathogens, veterinary pharmaceuticals and faecal pollution in streams, groundwater and produce.

It is acknowledged that stronger enforcement is necessary to monitor illegal land-clearing activities and mitigate environmental damage caused by the vegetable farmers in Cameron Highlands (Uphill task to ensure farmers do what’s right, the Star, Dec 11 2012). Yet there is so much more that consumers, retailers and policymakers could do to improve environmental quality and food health and safety standards.

In the aforementioned 2009 research paper, it was averred that media and legislation have had “less effect” in reducing agrichemical use than supermarket checks of produce. Supermarkets and major food retailers have a high level of influence and control over food quality and safety. Major retailers are therefore urged to ensure that their vegetable supply comes from farms which reach accepted health and safety standards and is checked for pesticide use and residues. Certification schemes such as the “Assured Produce” scheme practiced in the United Kingdom would help promote safer and more environmentally responsible methods of vegetable farming among major vegetable farms in Malaysia. Supermarkets should prohibit the use of banned pesticides by vegetable farms that supply produce to them, and make public the results of their own microbial and pesticide residue testing in a way that is accessible to the average consumer to enable consumers to make informed choices, bearing in mind that not everyone has the advantage or leverage of choosing organic over conventional produce.

Vegetable farms should be given incentives (such as accreditation) for employing responsible practices, such as drip irrigation to conserve water use and crop rotation to improve soil quality, and for meeting best management practices for pesticide storage and use. All manure used should be properly composted and incorporated into soil to prevent microbial contamination. To minimise pest damage, farmers could be educated on methods such as constructing protective barriers, encouraging biological pest control, choosing pest-resistant crop varieties and the use of “trap crops” to lure pests away from main crops. Regulations must be implemented to minimise pesticide drift to other crops and off-site areas and to halt pesticide applications during rainy and windy seasons.

Measures taken by the authorities apart from enforcement measures against farmers could include creating sediment traps to capture contaminated runoffs before they flow into streams, perhaps by way of constructing reed or water hyacinth beds. Buffer zones should be demarcated around sensitive zones. All potential sources of contamination should be identified and eliminated, or at least managed.

Food security and safety are public policy issues, and sound public policy decisions require an understanding of long-term social, environmental as well as economic consequences. Rising environmental literacy, changing consumer preferences, legislation and enforcement are all powerful forces that have the potential to create advances in agriculture that do not compromise human or environmental safety.
