Day 2: Nature catches and stores every drop of sunlight
When we observe nature what we see is plants reaching out in all directions to trap the energy of the sun. Only plants (except some odd exceptions) can do this, using chlorophyll to turn sunlight into sugars and starches; stored forms of energy, photosynthesis.
Simply put they use the energy of sunlight to join CO2 and H20 together, forming sugars, starches and carbohydrates. When we digest these sugars we break the bond, releasing the energy and the CO2 and H2O becomes available to the environment again.. it’s a simple system and pretty amazing in its power when you think about it. This idea of catching and storing available energy is the backbone of the second of David Homgren’s permaculture principles.
Here at Sector39, as a training enterprise we are developing an ambition to evolve our teaching processes into a permaculture academy. If we are to reach more people and spread permaculture wider we will need to train more teachers.
Permaculture is all about learning by experience, so in this PDC we are trying to create the opportunity for new teachers to learn and gain experience. Along with 43 participants we have 6 trainee teachers and three experts as well developing practical tasks relatiing to the course content. Early days maybe but we are reciving invitations to teach in more and more places and this is driving us to think more seriously about this proposition. So in some ways we have the aim of catching and storing the experience of the course by providing learning experiences that will in turn create new teachers.
What we human do in the next 50 years dictates what will happen in the next 10,000 for planet earth.
Professor Johan Rokstrom
On the evening of day one we watched the WWF climate change lecture from Dec 2015 led by Johan Rokstrom. We are confronted with the stark reality that humans have passed the carrying capacity of the planet. Human activity is now the most significant factor affecting the atmosphere and climate of planet earth. This new era of human driven global change is to be known as the ‘anthropocene’.
The upside of reality is that if we humans are the most significant force for destruction on the planet, then we can also be a force for repairing it. Catching and storing energy means building soils, adding carbon via humus, compost, mulches, biochar, low tillage and no dig systems, working with the biology of the planet to heal at least some of the damage we have done. It was only in about 1990 that humans became this dominant presence, and over the coming 30 years we will have to fix it, if we wish to preserve any semblance of the world we evolved to be part of.
Permaculture is fun, a PDC generates a huge amount of positive energy but underlying the work we do are huge challenges and potentially terrifying threats. Facing these challenges will take a great many people working together towards common goals and with a common vision, I honestly believe permaculture is the best tool we have to achieve this.
