Learning Landscapes: Adapting to Change Through Collective Creativity

Use Creativity and Adapt to Change

We are in the midst of change as spring has sprung. Many people are adapting to this change in the natural landscape by spending more time outside, watching the bees emerge to begin pollinating trees and plants, or perhaps planning or even beginning to plant spring crops. Experienced gardeners often reflect over last spring’s results in order to creatively adjust their plans for this year.

Shouldn’t we do something similar in the learning landscape or even in our personal and social landscapes? With this in mind, how can we use the framework of permaculture, a whole systems thinking framework, to work with our children to consciously and creatively make regenerative learning landscapes that reflect the inherent balance, stability and harmony of nature? How can we use this to help us work with our children to use creativity and adapt to change?  Read the rest of this entry »

Entomology: Lessons from the Garden

Multivotines vs. Univoltines: Adapting to Climate Change

I have just returned from a horticultural conference in Boston. One of the more interesting workshops was given by Michael Raupp, Ph.D, Professor at University of Maryland on climate change and plant pests. Thankfully, at least in this area, we are no longer talking about, “is the climate changing?” But what are the implications of climate change, and how does it affect families in western Massachusetts?

For insects, climate change is much more serious than just a bad hair day. There are many environmental factors that influence insects, but the primary one is temperature. As the environment gets warmer, some are winners and others are losers. Within the realm of insect pests – a major concern for farmers and gardeners of any scale – there are clear winners and losers due to the ways in which each species reproduces. The winner in the climate change war are multivotine insects, species who are able to reproduce multiple generations each year. On the losing side are univoltines , whose reproductive cycle makes it impossible to produce more than a single generation in a year.

Multivoltines have historically been hard to control as their ability to adapt to environmental conditions and pesticides is legendary – pesky aphids are a prime example of such a species. Because they have so many generations per year, adaptation of the species happens very quickly – hence an insect with the ability to persist, even as the conditions in its environment change. Univoltines such as the gypsy moth, on the other hand, reproduce slowly and, therefore, evolve slowly as well – making populations more susceptible to climate change-related damage.

While it’s impossible to see aphid and gypsy moth populations for yourself during the winter, it’s still possible to learn about this phenomenon as a family while the ground is covered with snow. Instead of aphids and moths, think about dandelions and apple trees. During the summer, dandelions pop up everywhere and go to seed fairly quickly. The seeds, blown by the wind, grow more and more generations of dandelions before the warm weather ends. Apple trees, on the other hand, take years and years to begin producing apples. Instead of reproducing quickly, multiple generations of apple trees can take a century or more to exist. Which of these species do you think might be more easily affected by a climate in which the temperature continues to rise? The one that takes longer to reproduce, of course. And which one is generally considered to be more desirable and valuable? The slow, slow apple, of course.
