School gardens improve health and academic performance, reduce discipline problems

\"\"

Nature Deficit Disorder, a term coined by Richard Louv in Last Child in the Woods, refers to the constellation of problems that occur when children become disconnected from nature. Nature deficit disorder can be prevented by creating green spaces on school grounds.

Having a school garden transforms a barren schoolyard into an attractive space that reconnects students to the natural world. Gardens not only make school grounds more appealing, they can also produce tangible benefits in the form of better health, enhanced academic performance, and reduced disciplinary problems.

Green spaces provide health benefits

The National Environmental Education Foundation (2010) summarizes a number of research studies on the health benefits of time spent in green spaces:

School gardens encourage kids to eat healthier foods

Many of the problems students face, ranging from ADHD to obesity, originate with unhealthy eating. Dr. Alan Greene (2010) reports that ADHD diagnoses have tripled over the past 20 years, and the incidence of depression and anxiety disorders has increased as well due in part to mass consumption of junk food. Dr. Greene notes that taking supplements won’t address the problems associated with poor diet because many nutrients found in whole foods, particularly fresh produce, work synergistically.

Replacing foods made from refined sugar and flour with produce is beneficial, as simple carbohydrates quickly enter the bloodstream, causing a fluctuation of glucose levels that can have negative effects on mood, memory, judgement, learning, and behaviour. According to Dr. Kathleen DesMaisons (1993), people who are sensitive to refined sugar are more likely to suffer from depression, poor impulse control, anger, aggression, fatigue, moodiness, concentration difficulties, and low-self-esteem. Children are particularly susceptible to these problems.

Studies have shown the benefits of eliminating artificial colours and preservatives and having children eat more fresh produce and complex carbohydrates. For example:

School gardens can potentially bring about these benefits by showing students where food actually comes from and encouraging them to eat lots of fresh produce. Studies and teacher observations of school gardens have shown that young people are far more likely to eat fruits and vegetables that they’ve grown themselves. For example, of the 4th through 6th graders at a “Delicious and Nutritious Garden” YMCA summer camp who had the opportunity to grow their own produce, 98% enjoyed taste testing the produce and 93% enjoyed cooking it.

Academic and behavioural benefits of environmental education

School gardens enable teachers to provide on-site environmental education, and studies have shown that environmental education has positive effects both on both student behaviour and academic performance. A national study conducted by the State Education and Environmental Roundtable (2000) found that environmental education students scored higher than their traditional education counterparts in:

They also scored higher in 84% of all assessments of attendance and discipline, largely because students in environmental education programs tend to be more engaged and enthusiastic about learning, and take more pride in their accomplishments.

Both behavioural and academic improvements are often dramatic. According to the National Environmental Education Foundation (2010):\"\"

  1. This is a very interesting article, unfortunately there's not always enough space for a garden, and not enough money, too!
